Illustrative example
A duplicated line after a partial receipt
- Original issued invoice
- USD 1,200
- Confirmed receipt
- USD 500
- Reviewed duplicate line
- USD 100
- Approved corrected charge basis
- USD 1,100, document process confirmed separately
- Remaining amount after reviewed allocation
- USD 600
Fictional arithmetic after an approved USD 100 correction. The example does not select a jurisdiction's required document type.
See the recorded product workflowDecisions to make before billing
Invoice correction starts by establishing which version the client has received. A typo in an unsent draft is a different situation from an amount error on an issued invoice that has already been partly paid. Preserve the relevant original record before deciding the correction method.
Define the error precisely: recipient, billing entity, PO, description, quantity, rate, tax or total. Compare it with the approved evidence and identify any effect on an open balance or received payment. A small rounding difference and a duplicated service line should not be handled as if they were the same problem.
The appropriate document process depends on your system, transaction and applicable requirements. Some corrections use a linked credit or replacement document rather than a silent edit. This guide records the review steps; it does not claim InvoiceAgent issues credit notes or choose a universal tax-document rule.

Outcome
Use this page to move from general research into a calmer, more repeatable invoicing process.
Work through the billing decision
Capture the original and expected value
Save the invoice ID, sent file and delivery reference. Record the field's current value, expected value and supporting agreement or approval. Check whether the client processed or paid the original.
Approve the supported correction
Ask the billing owner to determine the required document process, numbering and references. Separate administrative changes from financial adjustments, and reconcile any existing receipts before approving a new balance.
Close the loop with the recipient
Explain what changed and how the resulting document relates to the original. Save the correction and delivery references, confirm the right recipient, and review queued reminders or duplicate submissions affected by the change.

Deleting history to make records look tidy
A missing original makes it difficult to explain what the client saw and paid. Preserve the relevant document and correction relationship under your process.
Avoid this
Fixing the PDF but ignoring the balance
An amount correction can affect receipt allocation, an overpayment or a follow-up message. Reconcile those records rather than changing only the displayed total.

Questions people usually have before changing the workflow.
Can I simply edit an unsent draft?
Use your supported draft-edit workflow and preview it again. Confirm it has not already been issued or scheduled in a way that could send a stale version.
Does every correction require a credit note?
No universal rule is supplied here. Determine the process appropriate to the transaction and applicable requirements; an administrative reference and an amount correction can differ.
What if the original was already paid?
Keep the confirmed payment visible and review its allocation against the approved correction. Any refund or additional charge needs its own authorized decision.
