Agency finance · Credits & adjustments

Track client credits and billing adjustments cleanly

When an agency issues a credit note or adjusts an invoice — a scope was cut, a deliverable slipped, a client was overbilled — that change needs to be traceable back to the original invoice. Recording each credit with its reason, amount, the invoice it references, and the attached credit document keeps a clean audit trail in the client folder. Cash Workspace gives you one place to record adjustments and attach the credit document beside the original.

The problem

Why credits and adjustments get lost

Credits are issued ad hoc and rarely linked back to the invoice they change, so the client's true balance becomes hard to reconstruct.

  • A credit was issued but you can't tell which invoice it applied to.
  • The reason for an adjustment — a cut deliverable, a goodwill credit — isn't written down anywhere.
  • The original invoice still shows the full amount, with no note that it was credited.
  • When a client disputes their balance, you can't show the adjustment trail.
  • At year-end, billed totals don't reconcile because credits weren't recorded against invoices.

The workflow

Record each credit against its invoice

For every credit or adjustment, note the reason and amount, reference the original invoice, and attach the credit document in the client folder.

  1. 1

    Open the client folder

    Go to the client's folder where their invoices already live, e.g. 'Lumen Brands'.

  2. 2

    Record the credit

    Create a credit record with the credit note number, amount, and date issued.

  3. 3

    Note the reason

    Write down why — overbilled, scope reduced, deliverable delayed, goodwill — in plain language.

  4. 4

    Reference the original invoice

    Link the credit to the invoice number it adjusts so the trail is clear.

  5. 5

    Attach the credit document

    Attach the credit note or adjusted invoice PDF beside the original invoice.

  6. 6

    Update the invoice note

    Note on the original invoice that a credit was applied, with the credit's reference.

Record structure

What to record for each credit or adjustment

A consistent record keeps every adjustment traceable to the invoice it changes.

Credit note number
A reference for the credit, so it can be cited later.
Client
Whose account the credit applies to.
Original invoice referenced
The invoice number this credit adjusts.
Reason
Why the credit was issued — overbilling, scope reduction, goodwill, error.
Amount
The credited amount and currency.
Date issued
When the credit was issued, so the trail is dated.
Credit document (attached)
The credit note or adjusted invoice attached to the record.
Applied note
A note on the original invoice that a credit was applied.

Common mistakes

Mistakes to avoid

  • Issuing a credit without recording which invoice it adjusts.
  • Leaving the reason blank so the adjustment can't be explained later.
  • Not attaching the credit document, so only the amount exists with no proof.
  • Failing to note on the original invoice that a credit was applied.
  • Recording credits inconsistently so year-end totals don't reconcile.

FAQ

Credit and adjustment records FAQ

How do I link a credit to the right invoice?
Record the original invoice number on the credit and add a note to that invoice that a credit was applied, so the two are connected from both sides.
Does Cash Workspace issue credit notes for me?
No. You create the credit document yourself; Cash Workspace records its number, reason, amount, and referenced invoice and stores the attached document for the audit trail.
Why record a reason for every adjustment?
A plain-language reason — overbilled, scope cut, goodwill — means anyone reviewing the account later understands why the balance changed.
