PreviewExactly what gets sent

Send invoice

A separate email is sent to each recipient, with the PDF attached, from your Gmail.

Gmail isn't connected

Connect once and it stays connected.

Send me a copy (BCC)

Invoice history

Every invoice you've sent, with who received it and whether it's been paid.

Settings

Logo, signature, company details, Gmail connection and backup.

Logo on this client's invoices

No logo

Signature on every client's invoices

No signature

Signed by Title

Right-aligned under the payment details. A transparent PNG looks best; a name alone prints as a signed line.

Company registration printed on every invoice

Company reg. no. (EMBS) Tax no. (EDB)

Shared by every client profile. Some invoices are legally required to carry both — leave blank and they simply won't be printed.

Gmail connection

Send from your Gmail

Disconnect Gmail

Revokes the stored connection. You can reconnect any time.

Rebuild history from Gmail

Reads the invoices this app has sent from your Gmail and restores any missing records. Line items aren't in the email, so those come back empty.

Payments from Wise

Looks in the connected Gmail for Wise's "You got paid by …" emails. A payment for a month with no invoice yet is offered on the Invoice card; a payment for a month already invoiced marks it paid. Checked on each load and after six hours away.

Google OAuth Client ID

Only needed for the in-browser sign-in — see SETUP-GOOGLE.md. This ID is not secret; it only lets the app ask you to sign in. Sending always goes through your own Gmail.

Backup your data

Every client's defaults, recipients, logo & history live in this browser.

Start over

Restore this client to its built-in defaults.

Client

Everything below — numbering, currency, terms, recipients and history — belongs to the client you pick.

Numbers with no prefix can't be told apart from another client's when history is rebuilt from Gmail, so this client would sit that out.
