A payment option shoppers love can quietly shave real dollars off a retailer’s margin — and one Australian brand’s $451.70 sale shows how fast it adds up.
Buy now, pay later has become a default checkout button for millions of shoppers. It feels frictionless: split the cost into four instalments, pay on time, and there’s no fee for the customer. That “free” experience is exactly why platforms like Afterpay keep converting carts that might otherwise be abandoned. But for small businesses, the story looks very different behind the scenes.
An Aussie small business owner recently broke down the numbers on a single order worth $451.70. Afterpay’s cut on that sale was $30.14 in fees — money the customer never sees, but the business feels immediately. For brands running on tight margins, the difference between a good day and a stressful one can be measured in those hidden slices taken from each transaction.
Kellie Farley, who runs the streetwear brand Bae Bands, called Afterpay a “double-edged sword” for small merchants. On one hand, she says the platform drives a major share of her sales — as much as 40% of orders. On the other, the same feature that brings buyers through the door can quietly erode profits, especially when your products already carry shipping costs, returns risk, packaging expenses, and marketing spend.
Here’s the part many shoppers don’t realize: Afterpay typically charges businesses a percentage fee that can run up to around 6% per purchase, plus a fixed fee (often around 30 cents) and GST. Those numbers don’t look dramatic in isolation, but they compound fast — particularly on higher-value baskets, or on days when BNPL becomes the dominant checkout method.
And the fees don’t always stop there. Many small retailers process Afterpay through an ecommerce platform and payment gateway, which can mean additional payment processing costs on top. Farley explained that Shopify also charges a processing fee — for Afterpay payments as well as card payments — commonly cited around 1.75% plus another fixed fee. Layer those charges together and a sale that looks healthy at checkout can feel surprisingly thin once the payouts settle.
The $450 order reality check
A $451.70 cart can generate about $30 in Afterpay fees alone. If that same order also carries platform processing costs, packaging, and shipping, the final margin may be far smaller than shoppers assume — even before a business pays for ads or absorbs a return.
This tension explains why BNPL is so polarising among small retailers. Some merchants swear by Afterpay because it lifts conversion rates and increases average order values. Others drop it because the economics don’t work for their category — especially for products with tight margins or frequent returns. Many end up in the middle: they keep Afterpay because they can’t afford to lose the sales, but they watch every fee like a hawk.
Farley said she posted about the fees after realising many customers simply weren’t aware that businesses pay for the convenience. The responses mirrored a common reaction: shoppers were surprised, even a little uneasy, at how much of a purchase is skimmed off the top. Some commenters said they would reserve Afterpay for larger companies going forward, while others argued the option is now part of everyday commerce — especially when household budgets are stretched.
The broader numbers show why this debate keeps growing. Afterpay has more than 4.1 million customers in Australia, with a heavy skew toward Gen Z and millennials, and it’s used by roughly 129,000 merchants. With that kind of reach, opting out can feel risky for a small brand trying to compete for attention in a crowded market.
For shoppers, the takeaway isn’t “never use Afterpay.” It’s that the checkout choice changes who bears the cost. If you love a small brand and want them to keep making the products you buy, paying by card or bank transfer (when available) can sometimes leave more value with the business. If you rely on instalments to manage cash flow, you’re not alone — and many merchants acknowledge that BNPL can be the difference between a sale happening today or not happening at all.
For small businesses, the real challenge is balancing growth and sustainability. The same tool that brings customers back can also become a quiet “tax” on revenue, particularly when more buyers shift toward pay-in-four options during tougher economic periods. Understanding the fee stack — and how it interacts with product margins — is now as essential as choosing suppliers or setting shipping rates.
If you’re a merchant weighing the trade-offs, it helps to review Afterpay’s merchant pricing and fee structure directly on the provider’s site and model it against your real margin per order. You can start with the official details on Afterpay’s business information page and then run your own “worst day” scenario: what happens if 50% of orders shift to BNPL during a promotion, or if your average basket rises but return rates rise too?
