About Marketing Consultant credit notes

Marketing consultants issue credit notes when a campaign is cancelled after the strategy phase invoice has been paid, when a media budget is reduced and the management fee based on a percentage of spend needs to be adjusted, or when a client terminates a retainer with unused days in the current billing period. These are routine billing adjustments in a project and retainer-heavy profession.

The credit note documents each adjustment against the original invoice and gives both the client and their finance team a formal record. It also keeps your own accounts clean when revenue is recognised by project phase.

When to issue a credit note

Issue a credit note when a product launch campaign is cancelled after the strategy document is delivered and the next phase has already been invoiced. Use one when a client reduces their monthly ad spend significantly and the management fee, charged as a percentage, needs to be corrected for the current month. It also applies when a retainer engagement is terminated early and the remaining prepaid days are to be refunded.

Frequently asked questions

If I charge a percentage of ad spend and the client reduces their budget halfway through the month, do I issue a credit note?

Yes, if you already invoiced at the original budget level. Issue a credit note for the difference between the fee you charged and the fee that corresponds to the actual spend. Calculate it transparently and show both the original and revised budget figures in the credit note description.

A client cancelled a campaign but wants to use the credit for a different project. How should I document this?

Issue the credit note in the normal way. Add a note on it stating that the client has elected to apply the credit to an upcoming project rather than receive a cash refund. When you invoice for the new project, reference the credit note number and deduct the amount from the invoice total. Keep both documents linked in your records.

How do I handle a credit note when the original invoice covered both strategy and media in a single line?

Break the credit down into the components being returned, even if the original invoice did not separate them. Estimate the proportional value of each element based on your proposal or internal rate card. This gives the client a transparent breakdown and avoids disputes about how the credit was calculated.
