How to write a rate difference debit note
A rate-difference debit note charges the gap when the rate on the invoice turns out to be lower than the agreed or applicable rate — a contract rate applied late, a tier corrected, or a wrong unit rate. It adds just the difference.

Frequently asked questions
When do I use a rate difference debit note?
When the invoice used a lower rate than agreed — a late-applied contract rate, a corrected tier or a wrong unit rate. You charge only the difference against the original invoice.
How is it different from a price increase?
A rate difference corrects a rate that should have applied all along; a price increase reflects a new, higher agreed price. Both add the difference via a debit note.

What is the difference between a debit note and a credit note?
A debit note increases the amount owed on an invoice already issued — for an undercharge, additional charges or interest. A credit note does the opposite: it reduces or cancels what is owed. Buyers also raise debit notes to notify a supplier of a return or a claim.
