A claim that is a number in an email gets queried. A claim that is a number with the lines behind it gets paid, and usually without anybody reading the lines.
Key takeaways
Submit the line detail even though nobody asked for it.
Expect a difference, and expect it to be about definitions.
Reconcile before submitting, not after being queried.
A credit note is cleaner than a deduction. Take the credit note.
Submitted is halfway. Chase to received.

Their format, if they have one
Larger suppliers have a portal or a template, and a claim submitted any other way joins a queue that is measured in months. It is worth the twenty minutes of finding out what the format is, once, and storing it against the agreement.
Smaller suppliers have no format at all, and for them a one-page statement with a spreadsheet attached is more than they normally receive. Both cases are handled by the same rule field: how this supplier wants to be claimed from.
Why the figures differ
Fig 2. Three views of the same year’s purchases. The first gap is your own exclusions; the second is timing, and it is small enough to settle by email.
A business that claims on gross spend arrives at that conversation ten thousand pounds apart from the supplier and looks either careless or opportunistic. A business that has already applied the exclusions arrives fifteen hundred apart, which reads as two competent parties with a timing difference.
Reconcile before you submit
If the supplier publishes a statement of your purchases, compare it to your own figure before the claim goes out rather than after it comes back. The differences are almost always the same handful: a credit posted in the wrong period, a delivery invoiced after period end, one range you thought qualified and does not.
Each of those is resolvable in one email when you raise it. Each of them is an argument when they raise it, because by then you have asserted a number you cannot support.
Credit note, not deduction
Two ways to get paid, and why one is much better
A credit note is issued by the supplier, references your claim, and settles cleanly against your account.
A deduction is you short-paying an invoice by the rebate amount and telling them why.
Deductions feel faster and are, for about six weeks, until their credit control system treats you as being in arrears.
Then it becomes two problems: an unresolved rebate and a payment dispute, and they are now handled by different people who do not talk.
Take the credit note, and chase it like an invoice. It is the same money with none of the second problem.
The exception is a supplier who has ignored three claims and two chases, where a deduction with a clear explanation is a legitimate escalation. That is a decision by a person, taken deliberately, and it should never be something the system does on its own.
The claim is not the end
The average gap between a submitted rebate claim and a received credit note is measured in months, and the most common reason for a claim never being paid is that nobody followed it up after the first submission.
Which is why the claim record carries a chase clock from the day it is submitted, exactly like an unpaid invoice, and why the reporting counts received rather than claimed.
