Your transaction fee percentage is a per-business setting that gets applied to every card revenue entry. Updating it is a thirty-second edit that takes effect immediately — but only forward-looking, in keeping with the snapshot pattern.
01 Where do I change my transaction fee?
Open Settings → Business profile, where the Transaction fee % field sits right below the tax rate. Type the new percentage as a decimal — for example 1.75 for 1.75% — with no percent sign, then click Save, and a green toast confirms. The fee is a per-business setting that applies to the card portion of every revenue entry from that moment forward, so a thirty-second edit is all it takes.
02 What does changing the fee touch?
The new rate applies to every future revenue entry from the moment you save, and only to the card (EC) portion of each entry — never to cash (BAR). There's no backdating, no recomputation of historical data, and no impact on your past P&L. The fee on yesterday's entries was computed with yesterday's rate; today's entries forward use today's rate.

03 What happens to my past entries?
Past entries are untouched. Each revenue entry stores its own fee snapshot at the moment it was logged, so changing the rate today never backdates onto them. If you genuinely need to correct an old entry — say your acquirer billed you the wrong rate and you discovered it later — open that individual entry and edit its fee field directly. For an ordinary rate change going forward, you never need to touch the past.
04 When does a fee change happen in practice?
There are three common triggers. An acquirer renegotiation — you hit a new volume tier or switched providers and your effective rate drops, say from 2.0% to 1.7%. An FX surcharge revision — your acquirer added or removed an FX margin on non-domestic cards. Or you discovered your old rate was wrong — the figure you typed at signup was the advertised rate, not the effective one. The list below works through each.
- Acquirer renegotiation. You hit a new volume tier or switched providers. Your effective rate drops from 2.0% to 1.7%. Update the field, future entries use the new rate.
- FX surcharge revision. Your acquirer added or removed an FX margin on non-domestic cards. Effective rate climbs from 1.8% to 2.1%. Update.
- Discovered your old rate was wrong. You finally read the statement carefully and realised the "1.5%" you typed at signup was the advertised rate, not the effective one. Update to your real effective rate.
