How Do We Check That Every MOT We Did Was Paid For, and Every Slot Fee Matches a Test?

MOT centres pay slot fees for each test and take payment from customers, but rarely compare the two. We build a check that matches tests, fees and takings.

Quick answer — TL;DR

An MOT centre pays for testing slots in advance, records tests in the official system, and takes money from customers through its own tills and accounts, but the three are seldom compared. We build a regular check that lines up tests done, slot usage and customer payments, and lists any test that was not paid for, any payment with no test, and any discount nobody approved.

A month of tests, and the numbers do not line up

At the end of the month the owner looks at the slot balance, the card machine totals and the invoices. The number of tests recorded does not match the number of MOT payments taken. Some of it is retests, some is account customers who pay monthly, and some is discounts given at the desk. Some of it nobody can explain.

Finding out means printing lists, comparing registrations and asking staff about individual days. It takes long enough that it happens rarely, if at all.

Three records that never meet

The test is recorded in the official MOT testing service. The payment for testing slots is made to the scheme in advance. The money from the customer is taken at the desk, online, or on account through your own systems. Each of these is correct on its own. Nothing joins them.

Retests, partial retests, discounts, trade customers and vouchers all make the comparison harder. A test with no matching payment might be a legitimate free retest, a trade account, or a mistake. Without a way to tell which, the owner has to trust that everything is fine.

Staff changes make it harder still. A desk assistant who knows that the builder's merchant pays monthly and the taxi firm gets a rate may leave, and the next person does not know which unpaid-looking tests are fine. Over time, the only safe assumption becomes that nobody really knows.

What an unreconciled month hides

MismatchPossible explanation
Test done, no paymentFree retest, account customer, or genuinely unpaid
Payment, no testDeposit, cancelled test, or wrong registration
Discount givenApproved offer, or one given without authority
Slot usage higher than tests invoicedRetests, aborted tests, or missing invoices
Account tests not billedTrade customers not invoiced at month end

Most of the time the explanation is innocent. The point is to know, rather than hope, and to catch the occasional real error while it can still be put right.

There is also a planning point. If slot usage and paid tests are compared regularly, you can see how many retests, aborted tests and trade tests you do, which helps when deciding how many slots to buy and how to price your trade accounts.

How we build the MOT fees check

  1. Tests done are taken from the records your centre holds, such as your own test log or reports you can download, by registration, date, tester and result.
  2. Customer payments are read from your till or garage system, card provider reports and accounts package, such as Xero or QuickBooks.
  3. Each test is matched to a payment by registration and date. Retests are matched to the original test so free and reduced fee retests are recognised under the rules you set.
  4. Trade and account tests are matched to the account, and any not yet invoiced are listed for month end.
  5. Discounts are compared with the offers you have approved, and anything outside them is flagged.
  6. A short exceptions list shows only what does not match, with room for a note explaining each one.

We work only with data your centre is entitled to and can export. We do not access official systems on your behalf unless there is a proper, permitted way to do it.

Month end, explained

At month end the check has matched almost everything. Three items remain: a test with no payment that turns out to be a trade customer's van not yet invoiced, a discount that was not on the approved list, and a payment against a mistyped registration. Each gets a note, and the trade invoice goes out that day.

The owner has a clear picture of what was tested, what was paid, and why the two differ.

  • Tests, slot usage and payments compared regularly
  • Retests and trade accounts recognised properly
  • Unapproved discounts flagged
  • Only exceptions shown to a person

Would you know if a test went unpaid?

  • You rarely compare tests done with money received.
  • Retests and trade tests make the numbers hard to follow.
  • Discounts are given at the desk without a record of why.
  • Trade customers are sometimes invoiced late or not at all.
  • Working out the difference takes hours, so it is skipped.

FAQ

Frequently asked questions

The questions readers ask us after this guide.

Still have a question?

Ask us directly — a senior engineer will get back to you.

Ask about your project

Do you connect to the MOT testing service?

Only where there is a permitted way to use the data. Otherwise we work from reports and records your centre already holds and can export.

How are free retests handled?

Using rules you set, retests are matched to the original test so they are not flagged as unpaid.

Does this replace our accountant?

No. It is an operational check. Your bookkeeping and accounts stay with your accountant and your accounts package.

What do you need to start?

A month or two of test records, till or card reports and invoices, and your list of approved discounts and trade accounts.
