Square will happily switch on Afterpay for your café, and a rep might frame buy-now-pay-later as free extra sales. Before you flip it on for your latte menu, it’s worth a clear-eyed look at what it actually costs and where it fits. The honest answer for a coffee shop is nuanced: BNPL is a terrible fit for a $5 drink and a genuinely useful tool for a $400 catering order — and knowing the difference is the whole point.
This guide breaks down what Afterpay costs a café on Square, how it works in Canada and the US, and the specific situations where it earns its fee versus where it just bleeds margin. It’s written for independent café and restaurant owners on Square.
What Afterpay actually is
Afterpay is a buy-now-pay-later service Square offers as a payment method. The customer splits a purchase into four interest-free installments over six weeks, with the first payment due at the time of purchase. There’s no cost to the customer for paying on time.
For you, the merchant, the mechanics are the important part:
- You get paid the full order amount upfront, at the time of purchase — you don’t wait for the installments.
- Afterpay takes on the risk of collecting the remaining payments. If the customer misses one, that’s Afterpay’s problem, not yours.
- In exchange, you pay a merchant fee of roughly 6% + 30¢ on the total order, with no fees on the installments, no monthly charge, and no activation fee.
So for cash flow, an Afterpay sale behaves like a normal card sale that settles in full. The catch is entirely in that fee.
The fee is the whole story
A standard card payment on Square costs you somewhere around 2.6%–2.9% + a fixed fee. Afterpay costs about 6% + 30¢. That’s roughly double your normal processing rate. Everything about whether BNPL makes sense for a café flows from that single fact.
On a $5 latte, a 6% + 30¢ fee is 60 cents — about 12% of the sale gone to fees, versus roughly 44 cents (about 9%) on a normal card. Paying that premium so someone can finance a coffee in four payments is, bluntly, absurd. No one needs an installment plan for a flat white, and you’re torching margin on your lowest-ticket item.
On a $400 catering order, that same 6% + 30¢ is about $24.30 — still more than a card, but now a small share of a large, healthy-margin sale, and potentially the thing that let a customer say yes to the bigger order. That’s the entire distinction: BNPL’s fee is only justified when the ticket is big enough and the installment option actually closes a sale you’d otherwise lose.
| Order type | Order total | Afterpay fee (~6% + 30¢) | Fee as % of order | Verdict |
|---|---|---|---|---|
| Single latte | $5 | ~$0.60 | ~12% | No — fee too high for the ticket |
| Lunch for two | $28 | ~$1.98 | ~7% | Rarely — small ticket, thin benefit |
| Bulk beans / merch | $120 | ~$7.50 | ~6.3% | Maybe — if it converts a bigger basket |
| Catering platter | $400 | ~$24.30 | ~6.1% | Yes — installments can close the sale |
| Bulk gift-card purchase | $500 | ~$30.30 | ~6.1% | Maybe — weigh against normal card rate |

Where Afterpay actually fits a café
Reframe the question from “should my café offer BNPL” to “which of my sales are big and occasional enough to justify a 6% fee.” That short list is where it can pay off:
- Catering and large pre-orders. A tray of sandwiches, coffee boxes for an office, an event order — these are exactly the higher-ticket, planned purchases where paying in four helps a customer commit. If you take catering, this is the clearest fit; pair it with our guide to accepting pre-orders and catering on Square.
- Bulk beans, equipment, and merch. Selling retail bags, a grinder, branded gear, or a subscription box online is a real basket where installments can lift conversion and average order value.
- Bulk or corporate gift-card orders. A company buying $500 in gift cards is a large one-off where the option can help — though weigh it against just taking a normal card. See selling eGift cards on Square.
- Holiday and seasonal spikes. The season when people buy gifts, cater gatherings, and stock up is when a bigger-ticket BNPL option does the most work.
Notice the pattern: none of these are your daily drink business. They’re the occasional high-ticket edges of a café, and that’s precisely where a payment method with a high fee but a real conversion benefit belongs.
Where it makes no sense
Equally important, the honest “don’t bother” list:
- Everyday drinks and pastries. Low ticket, high fee, no financing need. Offering BNPL here just raises your effective processing rate on your bread-and-butter sales.
- Anywhere you’re fee-sensitive already. If you’re actively working to reduce your Square processing fees, bolting a 6% method onto low-ticket orders works directly against that.
- As a headline feature of your ordering flow. BNPL should be an option that appears on qualifying larger orders, not something you push on a $6 checkout.
BNPL is a scalpel, not a banner. Used on the wrong orders it quietly doubles your fees; used on the right ones it can unlock a sale.
How it works on Square in Canada and the US
Availability and surfaces differ by country, so know your setup:
- Canada: Square sellers have offered Afterpay since 2022. It works on your Square Online site, Square Online Checkout links and buy buttons, Square Virtual Terminal payment-by-text, Square Invoices, and the Web Payments SDK — i.e. your online and remote-payment channels. Customers pay four interest-free installments over six weeks.
- United States: Afterpay is available across Square Online and Square’s online/invoicing tools, and Square also supports accepting Afterpay for in-person payments in the US.
- Eligibility controls: You can set a minimum and maximum order amount for when Afterpay appears as an option. This is the single most useful setting for a café — set a minimum high enough that BNPL only shows on the larger orders where it makes sense, and never on a single coffee.
That eligibility range is how you get the upside without the downside: configure it so buy-now-pay-later only surfaces on catering-sized and retail-sized baskets, and your everyday drink checkout is untouched.
The honest bottom line
For the core of a café — drinks, pastries, the morning rush — buy now, pay later is the wrong tool. The 6% + 30¢ fee is roughly double a normal card rate, and nobody finances a latte. Where it earns its keep is the edges: catering, bulk retail, merch, and big gift-card orders, where a higher ticket absorbs the fee and the installment option can be the difference between a yes and a maybe. If you take those orders, turn Afterpay on with a sensible minimum. If you don’t, you’re not missing anything.
Payment options are one lever; the bigger wins in a café usually come from owning your customer relationship — repeat visits, loyalty, and a direct line to regulars — rather than financing individual purchases. For the full picture of what card and online payments cost you, start with our explainer on Square fees for restaurants, and if you’re weighing whether an ordering app is even worth it, see does my coffee shop need a mobile app.
If you do want that direct, loyalty-driven relationship on top of your Square POS, that’s the niche Tany fills — a branded ordering app plus web ordering with self-running loyalty and push, at $99 CAD/month per location. But that’s a separate decision from BNPL: Afterpay is a payment option for your big occasional orders, not a growth strategy for your daily business.
