Sent invoices
Each invoice with its send channel, address, and date noted.
Receivables · Delivery proof
'I never received your invoice' is the most common stall on a late payment — and if you can't show otherwise, the clock effectively restarts. The fix isn't chasing harder; it's recording, at send time, how and when the invoice went out and what confirmed it arrived. A reply, a read receipt, or a client-portal upload timestamp all count. Cash Workspace lets you note the delivery details on each invoice and attach the confirmation so the answer is ready before you ever need it.
The problem
When delivery isn't recorded, a client can claim non-receipt and you have nothing to point to. The dispute isn't about the money — it's about proof.
The workflow
Record the delivery the moment you send, and add the proof of receipt as soon as it appears.
Note the channel (email, client portal, shared link), the address or location, and the exact date and time you sent it.
Look for a reply, a read receipt, or a portal 'viewed' timestamp that shows the client received or opened it.
Save the reply email, read-receipt notice, or portal screenshot to the invoice record as the delivery confirmation.
Note whether it's sent, confirmed received, or bounced, so you can see at a glance which invoices have proof.
If you have to send it again, record the new date and keep the original send on file so the history is clear.
Record structure
A short, consistent delivery record turns a he-said-she-said into a documented fact.

Attach the reply, read receipt, or portal screenshot to the invoice as your proof of receipt.

FAQ
Cash Workspace is a free workspace for organizing invoices, expenses, receipts, clients, and documents. This page is organizing guidance only — not tax, accounting, legal, or bookkeeping guidance. Cash Workspace does not connect to your bank, does not scan or read your receipts for you, and does not move or collect payments. Whether an expense is deductible depends on your situation, so confirm it with a qualified accountant or tax professional.
Start a free workspace and record how, where, and when each invoice was sent, with the confirmation attached, so non-receipt claims have an answer.
