The verdict in three sentences
The real cost of online acceptance is the commission plus fixed fees plus disputes, not just the headline rate. On 30,000 USD/month of volume, a fixed monthly fee and 1% of refunds can add the equivalent of 0.5 to 1 point to the nominal rate. Simulate the full cost before signing, including setup and recurring items.
The real cost items in 2026
2026 order of magnitude for an e-commerce store in Singapore accepting cards and local wallets.
| Item | 2026 range (USD) | Nature |
|---|---|---|
| Commission per transaction | 2.5% to 3.5% | Variable, the main line |
| Fixed monthly fee | 45 to 230 | Recurring |
| Setup / integration | 450 to 2,300 | One-off |
| Fee per refund | 0.8 to 3 | Per case |
| Dispute fee | 8 to 23 | Per case |
| Withdrawal / payout fee | 0.5% to 1.5% | On settlements |
The payout fee is often forgotten: getting the money to your account can cost 0.5 to 1.5% extra depending on the channel.
Simulation by monthly volume tier
Estimated total monthly cost (2026 order of magnitude), 3% commission + 90 USD fixed fee + 1% refunds, 23 USD average basket.
| Monthly volume | Commission (3%) | Fixed fee | Dispute/refund cost | Total cost | Real rate |
|---|---|---|---|---|---|
| 7,500 USD | 225 | 90 | ~75 | ~390 | 5.2% |
| 15,000 USD | 450 | 90 | ~150 | ~690 | 4.6% |
| 30,000 USD | 900 | 90 | ~300 | ~1,290 | 4.3% |
| 60,000 USD | 1,800 | 90 | ~600 | ~2,490 | 4.1% |
| 120,000 USD | 3,600 | 90 | ~1,200 | ~4,890 | 4.1% |
Reading: at low volume, the fixed fee inflates the real rate (5.2% instead of 3%). As volume rises, the fixed fee dilutes and the negotiated commission rate becomes the only real lever.

Mini case study
Wei, owner of an online apparel store in Singapore, processes 30,000 USD/month. Her real cost is ~1,290 USD/month, i.e. 4.3%, while she thought she paid 3%. By negotiating her commission to 2.7% above 22,500 USD and cutting disputes (better product descriptions, order confirmation), she drops to ~1,080 USD/month. Saving: ~210 USD/month, i.e. ~2,520 USD/year, without changing provider.
FAQ
Are local wallets cheaper than cards? Often yes on commission, but watch the payout fees to retrieve funds. Total cost depends on the withdrawal channel as much as the acceptance rate.
How can I cut the real rate without switching PSP? Negotiate commission above a volume threshold, reduce refunds and disputes, and batch payouts to limit fixed settlement fees.
Is the setup cost negotiable? Yes, especially if you commit to a volume. A 2,300 USD setup can often be reduced or spread against a term commitment.
What volume justifies negotiating? From 22,000 to 30,000 USD/month, a 0.3-point renegotiation earns 65 to 90 USD/month. Below that, focus on reducing disputes.
Should I offer multiple payment methods? Yes: offering wallets + cards lifts conversion, but each channel has its own fee structure. Model the weighted average cost by your customers' real mix.
