How to set up Afterpay for your small business in Australia (2026)
Afterpay drives 20–30% higher average order values and reaches a customer demographic that wouldn't otherwise shop with you. Setting it up as a small business is straightforward — if you know which of the three routes to take.

Afterpay has done to Australian retail what GCash did to the Philippines — built rails that a whole generation of customers expect at checkout. The merchants who offer it see measurably higher AOVs (20–30% average), more repeat visits, and access to the 18–35 demographic who don't carry credit cards.
If you run a small business in AU and don't offer Afterpay, you're leaving revenue on the table. Here's how to set it up properly in 2026.
The three ways to accept Afterpay
1. Direct Afterpay merchant account
Apply directly through afterpay.com/au/business. Best for high-volume retailers. You'll need:
- ABN registered for at least 6 months
- Business bank account in your registered business name
- Expected monthly sales of at least $5,000 AUD
- Physical address (no P.O. Box merchant accounts)
- 5–10 business day approval timeline
2. Through a payment gateway (recommended for most SMBs)
Payment gateways like Airwallex, Stripe AU, and Till Payments all offer Afterpay as a one-click enablement once you're onboarded with them. Benefits:
- Single dashboard for cards, Afterpay, Zip, PayPal
- Faster approval (1–3 business days typically)
- No separate Afterpay contract to manage
- Automatic reconciliation with your POS / e-commerce
3. Via a POS / e-commerce platform
If you run Shopify, Wemu, BigCommerce, or Magento, Afterpay is a built-in checkout option once you connect your payment processor. Easiest route — no separate application, no gateway management.
Afterpay fees in 2026
Afterpay charges merchants — not customers — for each transaction:
| Monthly volume | Merchant rate | Fixed fee |
|---|---|---|
| Under $10K | 6% + GST | $0.30 |
| $10K – $50K | 5% + GST | $0.30 |
| $50K – $250K | 4.5% + GST | $0.30 |
| $250K+ | 4% + GST | $0.30 (negotiable) |
Why the rate is higher than cards
Afterpay bears the full risk if a customer defaults — you're paid immediately, they chase late payers. The merchant rate is essentially an insurance premium that's always worth it if the demographic is your target customer.
Common Afterpay setup mistakes
- Using a personal ABN-less account — Afterpay requires a registered business ABN with trading history
- Hiding Afterpay at checkout — display the Afterpay badge on product pages and in the cart for the AOV lift
- Not enabling the Afterpay order-minimum — set a floor ($20–$40) so you don't lose margin on tiny transactions
- Skipping refund flow training — Afterpay refunds are unique (the customer's payment schedule adjusts), so brief your staff
How Wemu integrates Afterpay
Wemu plugs Afterpay into your booking and shop checkout natively through Airwallex. One payment-processor onboarding, and every sale — card, Afterpay, Zip, PayPal — lands in the same dashboard with GST-compliant tax invoices auto-generated. The Bookkeeper Agent reconciles the Afterpay settlement dates (typically T+2) against your revenue automatically.
