Switching card reader provider without losing a trading day

A practical UK switching plan: when it is worth moving, how to overlap providers safely, what to check in your contract, and how to keep bookkeeping clean across the change.

Short answer

Short answer

Run both providers side by side for a couple of weeks. Order the new reader, take real payments on it, confirm a payout has landed, then cancel the old one — and keep the old account reachable until your refund window has closed.

First, check it is worth moving

Begin by taking a meticulous approach to evaluating your current expenses. Gather three months of detailed statements from your current card reader provider. Calculate what you actually paid by dividing the total fees by your total card turnover; this will give you your real effective rate. It’s essential to compare this with the effective rate the alternative would yield based on the same financial data, rather than its advertised headline rate. This step ensures you gain an accurate perspective of the potential savings.

Next, consider all potential costs associated with the switch itself. This includes the expense of new hardware, any exit fees from your current provider, and the value of your own time — typically, a switch might take several hours. If, after all calculations, the savings amount to less than fifty pounds a year, it might be wiser to remain with your current setup and focus on more profitable activities. However, savings in the range of two to three hundred pounds annually signify a compelling financial incentive to proceed with the switch.

Cost savings aren’t the only reason to consider switching. Factors such as slow settlement times, lack of printed receipt options, subpar reporting tools, or customer support that is difficult to access can all justify a move, even if cost savings are minimal. Always run your figures through our fee calculator to ensure you make an informed decision.

Read the exit terms before the entry terms

Prioritize understanding your current provider's exit terms before you are dazzled by a new provider's terms. Pay close attention to minimum contract durations, early termination fees, whether hardware was purchased or rented and must be returned, and any cancellation notice periods. These details can significantly impact your decision-making process.

It’s also vital to ascertain what happens to your funds during the transition. Most providers manage the settlement of outstanding balances as usual after closure, but some may retain a reserve to cover potential chargebacks over a specified timeframe. This step is particularly important if your business often processes high value transactions or has a high return rate.

Get the closure terms in writing

Request a written confirmation via email from your current provider's support team detailing any exit fees, hardware return requirements, and the expected date of your final payout. An email provides a tangible record that can resolve potential disputes months later, unlike verbal assurances over the phone.

The overlap plan, step by step

A low-risk switching sequence for a small business. Timings are indicative.
StageWhat you doOld provider
Week 0Apply, verify identity, order hardwareLive as normal
Week 1Set up the app, add staff, test a £1 sale and refund itLive as normal
Week 1–2Take real payments on the new reader; confirm a payout landsLive as backup
Week 2–3Move takings fully to the new readerIdle, kept open
Week 3+Export historic reports, then request closureClosed after refund window

The most crucial step in this process is verifying the new provider can process payouts reliably, not just sales. Many card readers may accept payments seamlessly yet encounter issues such as wrong bank account details, identity verification problems, or ongoing reviews only when the first payout is due. As a rule of thumb, never cancel your old provider until you see actual funds deposited into your bank from the new one.

Keep refunds possible

Refunds must typically be processed through the provider that managed the original transaction. If you prematurely close your old account the same week you transition to a new provider, a customer requesting a refund two weeks later could result in complications. You would need to handle refunds manually via bank transfers without the convenience and security protections offered by your card reader provider.

To safeguard against this, keep your old account open for at least the duration of your return policy. Extended account activity may be necessary if you sell goods with warranties or deposits. For pay-as-you-go accounts, leaving them dormant incurs no cost. If your previous provider charges a monthly fee, inquire if it's possible to cancel the active subscription while retaining refund functionalities.

Protect your records before you close anything

Ensure access to all historical transaction data before closing any accounts. Once an account is closed, the retrieval of records may become incredibly challenging, if not impossible, as providers are not always obliged to assist with this. Prior to cancellation, export all essential documents like monthly transaction reports, settlement summaries, fee invoices, and VAT documentation for the entire period you were operational with them.

Store these files in a reliable location, such as a secure cloud storage service or your business's accounting system, marking them with clear dates for easy reference. This foresight is crucial, especially for compliance and audit purposes, as your business could be required to furnish such documents several years down the line, and claiming that the provider deleted your records does not suffice.

Tell the people it affects

Communication with affected parties is crucial during any transition. Employees must be informed about which card reader is active, how to operate it, and who to contact if issues arise. A brief training session held during a quiet schedule can avert potential chaos during busy times. It's also an opportunity to allocate individual logins to employees to enhance accountability and security.

Your bookkeeper should be informed of the switch and provided with reports from both the old and new providers. Pay particular attention to the transition month as it spans two providers, increasing the likelihood of errors, especially if there are discrepancies in how providers manage fee settlements.

Additionally, update all references to the old provider, such as bank feeds, accounting software rules, integrations with booking or invoicing tools, and any published payment links. A broken link could result in lost sales, affecting your bottom line.

It is crucial to compare potential new providers accurately on all fronts, not just price. How card reader fees work is an invaluable resource for understanding why a lower advertised rate might actually result in higher costs when all fees and settlement methods are taken into account. Utilize the fee calculator to break down and compare the comprehensive effective rates of competing offers.

Be aware of two common challenges during switching: discrepancies in payout schedules, which are outlined in settlement times, and ongoing compliance obligations. Transitioning providers does not absolve responsibilities such as PCI compliance, which is essential for securing cardholder data. Information about these requirements can be found in the PCI compliance guide. When considering new providers, visit the comparison page, and if Tide is an option, explore the Tide Card Reader hub and their latest offer conditions to fully understand their offerings.

Frequently asked questions

Will switching interrupt my ability to take payments?
Not if you overlap. Keep the old reader live until the new one has completed a real sale and a real payout, then retire the old account. The only businesses that lose a trading day are the ones that cancel first.
Am I locked into a contract?
Most small-business card readers are sold without a minimum term, but not all. Check for a minimum contract period, an early termination fee, and whether the hardware is owned or rented before you commit to leaving.
What happens to refunds for old sales?
A refund normally has to be issued through the provider that processed the original sale. Keep the old account open, with a small balance or a valid card on file, for at least as long as your returns window.
Do I have to tell HMRC or my accountant?
There is nothing to tell HMRC, but your accountant or bookkeeper will thank you for a heads-up and the changeover date. Two payment sources in one month is a common cause of reconciliation errors.
Can I keep my old hardware?
Only with the original provider. Card readers are locked to the provider that issued them, so a SumUp reader will not work with Tide and vice versa. Budget for new hardware as part of the switch.
How much do I actually need to save to make it worth it?
As a rough rule, if the annual saving after hardware costs is under about £50, the disruption is rarely worth it. Above a few hundred pounds a year, switching pays for an afternoon of admin many times over.
