Chapter 1 Payment Gateways 101: What to Know Before Choosing a Payment Provider Chapter 2 How to Protect Your Ecommerce Store from Payment Fraud
Chapter 3 How to Prevent, Dispute and Reconcile Chargebacks for Online Businesses Chapter 4 International Ecommerce: 3 Steps to Global Expansion


Figuring out the best ways to accept credit cards online and choosing the right payment processor can be overwhelming at the beginning. It is the lifeblood of your ecommerce operation.

If you can not properly take payments online, you have no business.

Before we dive into your payment options and how to get started, did you know:

5%average revenue loss

The average business loses a 5% of revenue to fraud every year. Resolving fraud costs more than $114,000.

Beyond fees, fraud and conversion, your brand’s ability to expand internationally can be squandered by your credit card processing choice. Do international buyers trust your chosen solution? Does that solution work cross-borders?

Throw in each provider’s fees, contracts and fine print, and you have a wildly complex decision in front of you. You need to consider a myriad of factors, and how they affect your business. There is no right or wrong answer — only what works best for your unique set of circumstances.

Take the time to do some comparison shopping before choosing a solution to accept debit and credit card payments. This guide will walk you through the process, giving you all the information you need to find the right match for your business, including:

  • How exactly your brand gets paid and how to get started
  • How MasterCard, American Express and Discover handle fees –– and how much you can expect to pay
  • The two types of fraud activity, and how a payment processor can help prevent the issue
  • How to handle disputes, and why lowering your risk of fraud reduces your chances of chargebacks
  • How consumer financing can increase conversion –– and which payment gateways offer it
  • Tips to expanding and selling internationally and selecting a payment provider that is globally recognized

Before we begin, know that there are three types of payment processors: merchant account + payment gateway, all-in-one solutions and simplified credit card processors. Here’s a quick overview of each.

Merchant Account + Payment Gateway

The traditional method for accepting payments online has been a combination of a merchant account and a payment gateway. Providers like SecureNet (USA), Authorize.Net (USA) and eWay (Australia and UK) fall into this category.

A merchant account is a special kind of business bank account that lets you accept credit card payments.

An online payment gateway connects your store and your merchant service account, and facilitates the processing of the payment transaction between the various parties involved, including your bank and the card issuer’s bank. Think of it as the digital version of a POS card swipe machine used in brick-and-mortar stores.

There are fees associated with both the merchant account and payment gateway, but there are a lot of options out there, and some have more competitive transaction fees or don’t charge setup fees.

Payment gateways can also offer greater control over security rules and customization; they may be a better fit for large businesses needing a more tailored solution.

One thing to note about using a merchant account/payment gateway combo is that you’ll need to apply for both, usually filling out forms and providing some financial information. Processing your applications can take a few days, so you won’t be able to jump right into accepting payments. After both have been approved, you’ll need to connect your account to the gateway and then your gateway to your store. Usually this involves configuring your store with API keys, shared secrets and tokens.

The benefits to using a payment gateway are that you usually have more handholding and personalized customer service along the way because the providers are large companies with big support organizations. Often you’ll be able to get a person on the phone to answer your questions.

Payment gateways can also offer greater control over security rules and customization; they may be a better fit for large businesses needing a more tailored solution.

All-in-One Solutions

These services, including PayPal and 2Checkout, combine an account and gateway into one solution, which can make setup quicker and easier.

They allow you to take all major credit cards and usually have favorable transaction rates. Plus most don’t charge monthly or setup fees for basic accounts, although you do have to pay a monthly fee for certain added features on some services.

Services like PayPal make setup quicker and easier. They also allow you to take all major credit cards and usually have favorable transaction rates.

In the past, one potential downside was that they didn’t always offer a seamless checkout experience. Depending on how your solution was set up, your customers may have been redirected off your site to pay for an order. This is no longer true. With PayPal powered by Braintree and One-Touch technology, you, the business owner, get to decide what your customer’s checkout experience is like.

And this is important, because PayPal is incredibly popular. It has more than 100 million users and powers 60% of online transactions. We recommend combining PayPal with another service — that way shoppers who prefer it can choose it, and those who don’t can have another option.

Credit Card Payment Processing, Simplified

Services like Stripe have removed much of the complexity out of taking payments online.

From a merchant’s perspective, these are very similar to the all-in-one solutions, but they usually integrate seamlessly with your store’s checkout, meaning the shopper never leaves your site. And they can be much quicker to set up — you can start taking various payment methods in a matter of minutes.

With these simplified payment processors, there’s no need for a merchant service account or payment gateway, and that translates to fewer fees.

With these simplified payment processors, there’s no need for a merchant account or payment gateway, and that translates to fewer fees. Rates are competitive with the all-in-one solutions, and most of these new processors also don’t charge setup or monthly fees. The experience is straightforward: the customer credit card is entered, and the payment processed — simple as that.

One thing to consider before choosing a simplified processor is that you usually don’t get quite the same level of traditional support. They tend to be very easy to use, so you may not need it. But if you do run into a problem with your credit card processing company, most support is done as self service via articles or through email — many of these providers don’t even staff a call center.

10 Questions All Businesses Should Ask a Payment Provider

For those looking for a top-level view of the issue, and a speedier read, here are the most important questions to ask a potential payments processing provider before you choose to use their services.

1. Are there different rates or fees associated with different types of cards?

Some services charge different fees to process different types of card transactions –– e.g. personal, business, debit and rewards cards –– as well as for different transaction amounts. Make sure you know exactly what you’ll be paying to process each type of transaction.

2. Do you charge “billbacks,” or are all charges related to a transaction billed in the same month?

It’s not unusual for a payment processor to entice you by quoting low rates. But sometimes that low rate only applies to certain types of cards (see question one). You may only find out after the fact that many of your transactions during the month didn’t qualify for that low rate.

For example, in January, you think you’re getting a 1.7% rate on your credit card transactions, but you processed several rewards cards. Even though you processed the transactions in January, come February, your processor charges you back, or bills you back, a higher rate. Now you have two different statements with two different rates for the same transaction, which makes it much harder to figure out the actual rate you’re paying.

3. What rates or fees do you charge when I swipe credit cards, enter them manually (key-enter) or accept them online?

To compensate for the risk of fraud, processors charge different rates depending on how you process a payment. Because there is less fraud associated with  cards that are physically swiped in a terminal (after all, you check IDs, right?), there is usually a lower rate. If someone calls you to buy something and gives you their number over the phone, the chance of foul play goes up a bit, as does the processing fee.

Online purchases have the highest incidence of fraud, so payment processors cover their risk by charging a higher rate. Make sure you know what those rates are and then figure out how much of each type of processing you’ll do to get a rough blended rate.

4. Do you charge a separate fee for your gateway?

It’s pretty common for processors to charge a separate fee for their payment gateway, usually on a per-transaction basis. So in addition to the standard transaction fee –– say 2.9% + $0.30 –– you’ll pay a gateway fee for each transaction.

5. When I refund a transaction, do I get back any of the initial fees?

Most credit card processors keep all of the fees for return transactions, and will most likely even charge an additional fee to process the refund. That means you can lose money every time a customer returns something. Be sure you are clear on how this process works, as it should inform your return policy. Many merchants sidestep this cost by issuing store credit for a returned item, rather than a refund.

6. What are the contract terms and are there early termination fees?

Most credit card processors impose a contract term for a specific amount of time, often one or two years. Many times, early termination or cancellation fees are part of the agreement. That’ll make it difficult for you to switch processors if you’re unhappy with how your account is handled.

7. What fees do you charge each month?

This question is deceptively simple since some processors might provide you with a seemingly small upfront monthly fee. But be sure to dig deeper — some additional fees might be hidden in the fine print. These can include fees for batch processing or fund transfers from a merchant account to your bank account, as well as statement fees. Processors might “waive” some of these fees to get your business, but could add them back in after a promotional period.

8. Is there a monthly minimum processing requirement or fee?

Some processors charge a monthly minimum fee, which you’ll pay if your monthly transaction volume falls below a certain amount. This can be a significant financial pain for early-stage businesses with few monthly credit card transactions.

9. Is there a limit on how much I can process?

Many processors limit the amount you can process based on your initial approval with them. Obviously, this can be frustrating if your business grows quickly or has a busy season — not to mention the negative impact that turning down orders will have on your business.

10. What type of support is offered?

When your payments hit a snag, will the processor be there to support you until you’re back up and running? Further, an automated phone system isn’t the same as speaking to a live person, so make sure to ask if they have live customer support. Low rate processing fees don’t mean much if you can’t reach someone to help when you need it most.

  • Online shopping, PayPal, and online payments are on the rise. Providing safe Merchant Account Services that are efficient should be a first priority for any savvy company that wants to not only stay on the pulse of the industry, but also forge ahead.

  • Hi there – Thanks ,

    BigCommerce have sent us a few emails
    confirming that Stripe is a valid payment provider. We were concerned
    about using them due to the many complaints about them “holding” funds –
    Paypal do not hold our funds , our first 2 transactions with Stripe
    resulted in them biling customers’ cards and holding onto their payments
    – which was a bad first impression. BigCommerce have put us at ease
    regarding Stripe’s practices.

  • @audioshopaustralia:disqus, please contact our customer support team and they can escalate your issue with Stripe’s tech support.

  • We’ve used Paypal for years but are looking to open a secondary processor “STRIPE”.

    Stripe , so far , have been very difficult to deal with – the BigCommerce connected successfully with Stripe and their Photo ID verification was completed. We then took 2 test payments and were about to ship them when Stripe “HELD” the payments re-requesting the previous ID verification.

    Why does Stripe bill customers’ cards when an account is not verified – I do not know. I’m currently waiting for Stripe to reply , at this point we are hesitant to add Stripe to our payment options because we have no way of knowing if Stripe can process payments correctly.

    I googled Stripe reviews following this and alot of people are complaining about a huge spike in chargebacks because , apparently , Stripe is very open to fraud etc. Is this true? Our thoughts , if Stripe turns out to process correctly , was to do a small deposit refund for all Stripe transactions and have the figure confirmed before shipping any Stripe transactions. Paypal have the seller protection which is of course a huge advantage.

    Does anyone have any experience with Stripe working correctly and any advice , pros , cons , etc?

    The payment processor “PIN” – Pin payments? – Have offered us a secondary facility but we are currently more interested in pursuing what Stripe have to offer – despite their 7 day settlement timeframe. This 7 day timeframe is actually quite helpful in our case because :

    1. It gives us time to investigate for fradulent transactions
    2. It gives us time to process the small refund to confirm the card holder is the one making the payment.
    3. Allows enough time to refund any suspicious payment without the payment being settled first.

  • Hey Iwein,

    Most payment gateways impose these kinds of limits as a safety measure to prevent fraud orders. So, ifyou’re trying to accept payments of $10k from international countries, that’s a heavy fraud risk.

    You may want to look at one of our high risk payment gateways. And, potentially a fraud app such as Subuno.

    In short, you can’t control your customer’s credit card company. Something like PayPal Bill Me Later would allow them to pay in installments. Or you can accept checks/bank transfers.

  • Iwein Fuld

    For, I’m searching for a solution that allows me to accept large payments (often more than €10.000) from international customers across the globe. CC companies impose limits that are frustrating my customers in non US or EU territory, and that is costly for us.

    Is there even any solution?

    Hi Samora, I would encourage you to look into either Paypal or 2Checkout.

  • Samora

    What online payment options are available to caribbean merchants? I can’t seem to find any.

  • flexsin

    Once we identify the top traffic-driving organic keywords, we test them out in our paid search campaigns (if we aren’t already bidding on them). The same practice can be done from PPC to SEO– identify revenue-generating keywords and then incorporate them into SEO efforts. Great article!

  • Jessica Malnik

    To enable Stripe, just go to Store Setup and Tools–> Payment. Click the “on” button. Then, you should receive an email confirmation.

  • Sounds good! HOW I can start using it? And another question – its possible that my Store will on UK IP ? Please let me know

  • Bill Hoyos

    It sounds great I’ve done my homework I would use google checkout PayPal and stripe but it doesn’t sound like stipe has I am very frustrated that stripe would not offer mobile card swiping like square or intuit etc does why would they NOT want all the mobile off site sales out there…..ITS IN THE BILLIONS OF TRANSACTIONS. ………WHEN THEY DO I’LL SIGN UP……UNTIL THEN ITS A DEAL BREAKER=NO SALE…….sorry:(

  • Simon

    When will you add any South African Payment gateways



  • Jessica Malnik

    You are correct, Chris. Stripe is available for clients in the US, Canada, UK and Ireland.

  • hi, did I just pick up that stripe was now available in the UK?



  • Jessica Malnik

    Hi Steven, unfortunately, that’s not possible. If it’s not mentioned in one of these two support articles, there’s a good chance it’s not supported at this time.

    That being said, if there is a particular payment gateway that you want, we would encourage you to add this to our Ideas site.

  • Can I use another payment gateway that is not listed for my big commerce site?

  • John Shannon

    Thanks, Jessica!

  • Troy Cox

    Hi Paul,

    Yes, that’s true. By requiring much less credit and financial information about your business, they protect themselves by holding money a bit longer. Having said that, they offer a process for reducing the number of days between the charge and the transfer to your bank account. More details are available on their site:

  • Troy Cox

    Hi Alberto,

    I’m sorry to hear about your experience. I can’t really comment on Stripe’s policy but if you are still looking for a payment solution and you are in the US, I recommend looking at SecureNet, which is available now as an option in your store’s admin.

  • Troy Cox

    Hi David, the rates quoted are for US and Canadian merchants. Stripe isn’t yet available in Australia and so the comparison might not be relevant.

  • Troy Cox

    Hi Diane,

    With Stripe (and many of our integrated gateways) your store’s checkout is guaranteed secure and guaranteed to use SSL security. Any of your shoppers can click on the padlock icon in their browser and verify the encryption security.

    Re the seal, you’re welcome to display (and in fact we recommend it!) the ‘Powered by Stripe’ badge on your site and in your checkout. There’s more information on Stripe’s website here:

  • Troy Cox

    Thanks for the feedback!

  • Troy Cox

    Hi Jimmy,

    No, Bigcommerce doesn’t charge you any extra to use Stripe.

    You’re welcome to purchase an SSL certificate for your own domain name but if you don’t, your store will automatically use the Bigcommerce shared SSL certificate. Using the shared certificate however means that the URL of your checkout will look something like

    Re currency, based on what you specify as your store’s default currency, all transactions are processed in that currency. With Stripe, US merchants must use USD and Canadian merchants have a choice between USD and CAD. Having said that, we have a free feature that allows you to display your products prices in any number of currencies and it can detect the shopper’s IP address (and hence country) and then automatically display prices in that country’s currency. However, as mentioned, the transaction in the checkout will be in the store’s default currency.

    I hope that helps.

  • Troy Cox

    Hi, in fact Stripe does support Discover (and JCB and Diners Club) for US merchants. Discover Card is not supported however in Canada.

  • Ben

    If the payment is processed by BC, what name shows up on the customer’s bill?

  • Hi guys,
    Thanks for offering this service and all the work you’ve put in to Stripe! It looks very tempting.

    I’m a start-up and paying $10/m, 20¢ per transaction, where security and Amex are extras; so it would make sense to go with Stripe.

    I would like to know if:
    – you charge extra for security or any other features for Stripe?
    – you’d be offering an SSL certificate to coincide with secure payment pages, similar to a major competitor of yours?
    – you accept payments in any currency?

    I’m looking forward to your response!

  • Hello I have Stripe and I love it my customers that are mostly in Brazil pay so quickly and easily. Most people don’t know or Care to know Paypal. It’s easy no questions about paying. If you dont need Cash Flow for 7 days for your business you will never regret this. Former: Paypal, Authorize, Payleap customer! Try it you can always change over.

  • Diane

    Does Stripe offer a clickable verification seal?
    I briefly switched to Securenet, but because they offer no way for customers to verify that I am a secure merchant during checkout, I went back to

  • Jessica Malnik

    That’s correct, Paul.

  • Jessica Malnik

    Hi Kurt, that’s a great question. The answer is it really depends on your specific business. In general, or Securenet is your best bet for high-traffic stores that are bringing 100,000s in revenue.

  • 2.9% + 30c per transaction is double what it should be. In Australia 1.5% is where I would be simon for new businesses. With CBA, ANZ, Bendigo banks being directly supported with BigCommerce these rates are achievable.

  • We tried to use Stripe and were turned down by them. We are a health food store that includes health supplements as you would find in any Main St., USA health food store. Stipe considers such a store a “pseudo-pharmaceutical” store and will not provide service. When a service company starts to apply its own legal definitions outside of the real legal system, store owners need to be very concerned about what other unreasonable policies lie out there.

    This policy has nothing to do with pharmacies that are in conflict between federal and state laws. After having discussed this absurd policy with their support group, I strongly suggest that stores stay away from this service.

  • Hi all,

    eWAY here, we link to Australian, UK and NZ acquiring banks and we’d love to get full BigCommerce integration. Overnight settlements are standard and we offer enterprise fraud prevention through our new API. Help us get the new API integrated by letting BigCommerce know you want it!

  • So with Stripe when an order is made we have to wait 7 days before we receive the payment for the order?

  • Karl


    I ran my store for a while with just PayPal and added a payment processor and now 50% of my sales are not through PayPal and my sales have went up dramatically. While PayPal is popular, not everyone uses it.

  • Kurt

    How does it compare with Authorize.Net?

  • Jessica Malnik

    Hi Nor, we recommend you use Securenet if you are bringing in more than 100k in revenue.

  • Nor

    Should I turn-off Securenet and go with Stripe? What are the pros and cons between these two?

  • Troy Cox

    Hi Curtis,

    There are many studies which show that you can increase conversion by offering multiple ways for your shoppers to pay. In your favorite search engine, just enter ‘ecommerce multiple payment methods’ to get a selection of studies. As well there are differences between PayPal and Stripe. With PayPal, your shoppers are redirected off site to make payment whereas with a processor like Stripe, you’re not. With PayPal, there is less friction, particularly on mobile, because the shopper doesn’t need to manually enter shipping and payment details. There are pros and cons to both.

  • Troy Cox

    Hi Casey,

    If you’re in the US, SecureNet is a good option. If you’re outside the US, this link will help you choose a payment processor:

  • Troy Cox

    Hi Charles,

    It’s completely safe to agree to the permissions when prompted. Stripe is a new breed of payment processor where the payment is processed by Bigcommerce on your behalf. By doing it this way, it’s much easier to start accepting credit cards. You’re right that traditional processors require you to supply API keys and token to get them working. Both work well but Stripe is much easier to get going.

  • I signed up for Stripe earlier today, but then realized that there isn’t really any advantage of offering both PayPal and Stripe, and so I turned it back off. PayPal seems to be way more flexible. I’m curious to know why Big Commerce has invested in this partnership when it doesn’t seem all that necessary.

  • When you go to the sign up link for Stripe, it says “Bigcommerce will have access to your data, and can create payments and customers on your behalf”. I’m not sure what exactly this means, but it seems different from SecureNet, unless I’m mistaken.

  • casey

    which payment gateway should I use for my client who also has a retail store so it is all in one account?

  • AllofUs

    I agree the information is pretty vague. I noticed that Stripe does not accept Discover. I’ll stick with SecureNet.

  • Have you had any feedback from Stripe users regarding problems they or their customers have encountered when using Stripe? That would be helpful to me in making a decision to change or not.

  • Hi Jessica- You should add Stripe to the linked Knowledge Base article. How does Stripe differ from Big Commerce Payments (powered by Secure.Net)? Both appear to cost 2.9% + $.30 per transaction fee. I assume they are similar, but Stripe is much quicker to set up with less paperwork and hoops to jump through.

  • Jessica Malnik

    Hi Tiger,

  • Jessica Malnik

    Hi Rowena, at this time, Stripe is only available in the US and Canada.

  • Can Stripe be used in UK? If not are there any all in one payment solution for the UK?

  • This is a brillaint idea – can we get it in the UK?

  • Stripe sounds like an reasonable choice, rates appear to be the same as what we currently have with paypal. I can not say I’m very fond of the seven day waiting period for funds to transfer.
    7 days is abnormally long. I would sign on right now if it wasn’t for the fact funds won’t transfer for a whole week.

  • The article was very general,but not any good for making any kind of decision. What we store owners really need to see is a comparison chart with real figures of the different payment options that big commerce has to offer.

  • Lea

    How long does Stripe take to fund an account after processing a payment? Our current processor takes 2 business days.

  • We need a UK Version of this – It takes ages to work through Sage Paperwork and get it integrated seamlessly so having one for us would be a huge benefit.

  • Jon

    Will there be a UK option any time soon?

  • Caroline

    And for Australia..?

  • Grizz

    Is Stripe for US-base stores only?
