Switching Card Payment Providers: Costs and Break-even
Know what it costs to leave, what the new offer includes and when the change starts to pay for itself.
The short answer
Before switching, confirm every existing agreement, obtain a complete alternative quotation and calculate cumulative costs over your intended period. Include exit, setup, migration and overlap charges. Plan the changeover and confirm the old contracts are closed; installing a new terminal does not do that automatically.
In this guide
1. Find every agreement you need to deal with
List the payment processor, terminal supplier, EPOS software provider, gateway and any finance company. Record the legal entity on each agreement, the minimum term, notice requirements, renewal wording and equipment return process.
Ask for a written cost to leave on a specific date, broken down by agreement. Check whether it covers notice, rental, outstanding services and equipment. A supplier’s general sales explanation is not a substitute for the terms of your own contract.
If a charge or renewal is disputed, resolve it separately. This guide explains comparison and planning; it does not determine your legal right to terminate an agreement.
2. Confirm the new offer and switching budget
Obtain the standard tariff, promotional terms, installation scope and new commitments. Check whether your existing software and equipment work with the proposed service. Include training, menu or stock migration, new hardware and any period when both systems must be paid for.
For a contribution towards exit charges, establish the amount, qualifying conditions, evidence required, payment date and any repayment clause. Treat an unconfirmed contribution as uncertain, not as cash already received.
Use a comparable written quotation. Structured pricing information can help you collect the inputs, but a full service and contract check still matters.
3. Calculate cumulative savings, including promotions
The current package costs £500 a month. The alternative costs £300 a month for the first three months, then £450. Switching costs total £600 at the start. Assume all other relevant charges are included.
| Month | Current | Alternative | Saving |
|---|---|---|---|
| 1 | £500 | £900 | −£400 |
| 2 | £1,000 | £1,200 | −£200 |
| 3 | £1,500 | £1,500 | £0 |
| 4 | £2,000 | £1,950 | £50 |
| 12 | £6,000 | £5,550 | £450 |
Cumulative savings reach zero in month three and remain non-negative through month 12. The standard recurring saving is £50 a month. Without the promotion, the same £600 switching cost would take 12 months to recover.
A promotion can also create an early saving that later disappears. The calculator reports lasting break-even within the selected period, not merely the first positive month.
4. Look beyond the comparison period
A 12-month comparison does not erase an 18- or 24-month agreement. List committed fixed payments remaining after the chosen horizon. Show them separately from the period total and make clear which costs they cover.
For example, if a £30 monthly rental is included in the monthly cost and six committed months remain after the comparison, that is a further £180 of fixed payments. Do not add it into the 12-month total or assume it covers future processing and every other obligation.
Only count an old obligation as settled where the settlement actually covers it. Avoid adding both an exit settlement and the same remaining payments.
5. Plan the operational handover
- Confirm approval, delivery, installation and the date the new charges begin.
- Check the payment, refund, receipt and reporting workflows you need, following the provider’s testing instructions.
- Train staff and establish a fallback for connectivity or device problems.
- Retain access needed for outstanding settlements, refunds and disputes.
- Give valid notice, return equipment as required and keep evidence.
- Check final old-provider bills and the first new-provider statement against the agreed terms.
Keep the quotation and your comparison report together. The first actual bill is the opportunity to check that the change delivered the expected pricing.
Common questions
Should I cancel before the new system is ready?
Plan the sequence around continuity and your notice requirements. Confirm dates and overlap costs with both suppliers rather than assuming immediate activation or cancellation.
What if break-even is outside my comparison period?
The change has not recovered its entered costs within that horizon. Consider a longer realistic period, a revised offer or retaining the current arrangement.
