Attaching payment confirmations to invoices you mark Paid

When a client pays, you mark the invoice Paid — but six months later, when someone asks 'did invoice #318 actually settle?', a status label alone isn't proof. Attaching the actual confirmation (a transfer receipt, a payment screenshot, a remittance advice) to each invoice the moment you mark it Paid means every settled invoice carries its own evidence. Cash Workspace lets you attach that document to the invoice record and note the date and method, so the proof and the status live together.

The problem

Why a 'Paid' label isn't enough

Marking an invoice Paid records that money arrived in your memory, but the supporting document usually lives in your email, your phone's camera roll, or your messages — disconnected from the invoice.

  • A client disputes whether they paid, and the transfer receipt is buried in an email thread.
  • You marked invoice #318 Paid but can't recall if it was the full amount or a partial.
  • Remittance notes for several invoices arrive in one email, so it's unclear which invoice each line covers.
  • Screenshots of payments sit in your phone gallery, never matched to the invoice record.
  • At year-end you can confirm a status but not produce the proof behind it.

The workflow

Attach proof the moment you mark Paid

Make attaching the confirmation part of the same action as changing the status, so nothing gets skipped.

  1. 1

    Locate the confirmation

    Find the proof of payment: a bank transfer receipt, a payment app screenshot, a remittance advice email, or a cleared-cheque image.

  2. 2

    Open the invoice record

    Go to the invoice that just got paid before you change anything else.

  3. 3

    Attach the document

    Attach the confirmation file directly to that invoice record so they're permanently linked.

  4. 4

    Record date and method

    Note the date the payment arrived and the method (bank transfer, card, cash, app) in the record.

  5. 5

    Set status to Paid

    Only now mark the invoice Paid, knowing its evidence is already attached.

Record structure

What to capture with each payment confirmation

A consistent set of details next to the attached file makes any later question answerable in seconds.

Invoice number
The invoice the payment settles, so the proof is tied to the right record.
Amount received
What actually landed, which may differ from the invoice total if rounded or short.
Date paid
The date the funds arrived, not the date the invoice was issued.
Method noted
Bank transfer, card, cash, cheque, or a named payment app — recorded as a note.
Reference / transaction note
Any reference number the client used, copied from the confirmation.
Confirmation attachment
The screenshot, transfer receipt, or remittance file attached to the invoice.
Full or partial
Whether this confirmation covers the whole invoice or only part of it.

Common mistakes

Mistakes to avoid

  • Marking an invoice Paid without attaching any proof, so the status is unverifiable later.
  • Leaving confirmation screenshots in your phone gallery instead of on the invoice record.
  • Recording the issue date instead of the actual date paid.
  • Not noting whether the confirmation covers the full amount or a partial payment.
  • Letting one remittance email cover several invoices without splitting it per record.

FAQ

Payment confirmation FAQ

Does Cash Workspace confirm payments for me?
No. You attach the confirmation you received and note the date and method yourself. Cash Workspace does not sync with your bank or process payments — it keeps the proof you already have organized against each invoice.
What counts as a payment confirmation?
Anything that evidences the payment: a bank transfer receipt, a payment app screenshot, a cleared-cheque image, or a remittance advice from the client. You attach whichever you have to the invoice record.
Where should I store the proof?
Attach it directly to the invoice it settles, rather than leaving it in email or your phone, so the status and its evidence are always in the same place.
