How to switch payment providers without losing a day of trade

Most merchants stay on an expensive deal for one reason: switching feels risky. In practice, a switch that's sequenced properly means no downtime, no gap in payouts and no nasty exit fee. This guide is the checklist we'd follow.

The 30-second version

• Audit first. Know your effective rate and what a better deal saves before you move.
• Check your contract for lock-in terms and early-exit fees.
• Overlap, don't cut over cold — run the new terminal alongside the old one for a day.
• Move payouts and reconciliations deliberately, not on a busy trading day.
• Keep the old account open until the first clean settlement lands from the new one.

Before you switch: do the maths

There's no point switching to save 0.05%. Pull a recent statement, work out your effective rate, and compare it against the market on a card processing costs basis — our comparison and calculator both do this. A switch is worth the effort when the annual saving comfortably clears any exit cost and a few hours of admin.

Check the contract you're on

Read your current agreement for three things: a minimum term, an early-termination fee, and any terminal lease that runs separately from the merchant facility. Leased hardware is the usual trap — the payments contract may be month-to-month while the terminal lease has 18 months to run. Knowing this up front tells you whether to switch now or time it to the lease end.

The switch checklist

1. Choose the new provider on card processing costs and terms. If you're torn, our head-to-head matchups give a clear verdict.
2. Apply and get approved before touching the old account. Onboarding can take a few days.
3. Set up the new hardware and process a small test transaction.
4. Run both in parallel for a trading day so staff learn the new flow with the old one as backup.
5. Redirect payouts to the correct account and update your bookkeeping/reconciliation.
6. Cancel the old facility only after the first clean settlement from the new provider.

Avoiding downtime

The single trick to a zero-downtime switch is overlap. Never cancel the old terminal until the new one has taken real money and settled it correctly. Do the cutover early in the week and outside your busiest hours, so if anything needs a phone call, support is available and the stakes are low.

Switching around the October 2026 reforms

With surcharging banned from 1 October 2026, acceptance cost lands squarely on the business — which makes an overdue switch more valuable, not less. If you're on flat-rate pricing that won't automatically pass through the RBA's lower interchange cap, switching or renegotiating is how you capture the saving. Check your exposure first with the surcharge calculator.
