Volume rebate
A volume rebate is a payment or credit that a supplier gives a buyer after the buyer has bought a certain quantity or value over an agreed period. It is worked out afterwards, on the total, rather than taken off each invoice.
Suppliers use rebates to reward loyalty and to encourage a customer to buy more from them than from competitors.
Rebate versus discount
A discount lowers the price on the invoice. A rebate is paid or credited later, once the buyer reaches the target. The buyer pays the full price during the period and gets money back at the end.
That timing is the main difference. A rebate leaves the invoice price unchanged and ties the reward to the buyer's total over time.
How a volume rebate works
An agreement usually sets out:
- The period, such as a quarter or a year
- The measure: units, weight or sales value
- The thresholds, and the rebate rate at each one
- Which products count
- How and when the rebate is paid, such as a credit note or a payment
Some rebates are a single rate once a target is met. Others are tiered, with a higher rate for each higher threshold. Some apply to everything bought in the period once the threshold is reached, often called retrospective. Others apply only to the amount above the threshold, often called incremental. Some agreements reward growth over the previous year rather than a fixed volume. The wording matters, so check which one you are agreeing to.
This is a general explanation, not tax or accounting advice. How a rebate is recorded depends on your accounting rules.
Why suppliers offer them
A rebate gives the buyer a reason to concentrate purchases. It also lets the supplier hold list prices steady. A seller may not want to cut the invoice price for everyone, but is happy to reward the customers who bring the volume.
An example from product sales
Say a plastics distributor agrees a yearly rebate with a moulder: 2% on purchases above 100 tonnes, 3% above 150. By the end of the third quarter, the moulder has bought 90 tonnes. The rep sees that the customer is close to the first threshold, and mentions it in the next review call. The customer decides to move more of its volume.
Say the moulder ends the year on 120 tonnes at $1,500 a tonne, $180,000 in all. If the 2% is retrospective, the rebate is 2% of $180,000, which is $3,600. If it is incremental, it covers only the 20 tonnes above the threshold: 20 × $1,500 × 2% = $600. Same volume, very different payment, which is why the wording matters.
The made-up figures are only an example. Real rates depend on the agreement.
Related terms

How PromptLab handles it
In PromptLab, prices and line discounts go on quotes, and customer price lists hold the agreed prices. For a rebate, write the terms in a note on the account, track progress against the target using the account's sales orders, and add a task for the review. The rebate itself is settled in your finance system.
Frequently asked questions
What is the difference between a rebate and a discount?
A discount reduces the price on the invoice. A rebate is returned after the period, once the buyer reaches the target.
Is a volume rebate paid in cash?
It can be paid by bank transfer or given as a credit note against future invoices. The agreement should say which.
What is a tiered rebate?
It is a rebate where the rate rises as the buyer passes higher purchase thresholds.
Does a rebate reduce the seller's margin?
Yes. Because it is paid after the sale, it is easy to forget when quoting. Include it when you work out the margin on a customer.
Are volume rebates the same as price breaks?
No. A price break lowers the unit price for a larger single order. A rebate looks at total purchases over a period and pays afterwards.
