Illustrative example
Example invoice email you can adapt
- Subject
- Invoice 1042 — September support — due October 5
- Message
- Hi Alex, attached is invoice 1042 for September support and the approved migration work. The total is $1,380 USD, due October 5, 2026. Please use the payment instructions on the invoice and include reference 1042. Let me know if your billing team needs anything else. Thank you.
- Attachment check
- Invoice number 1042; support $1,200; migration work $180; total $1,380 USD; matching deadline and payment instructions.
- After dispatch
- Check Sent and the recorded send time. Review any archive error separately; record confirmed receipts against the invoice.

See the recorded product workflowFrom invoice details to an attached PDF
InvoiceAgent prepares the PDF and email when an eligible invoice is processed. The attachment is generated from the invoice record, so you do not need to export a document and manually attach it to an email draft. If connected time imports or currency conversion are enabled, review those inputs because dispatch can use newer values than an earlier preview.
Write a subject that identifies the invoice and a short message explaining the work, amount, deadline, and payment instructions. Confirm the client recipient in the saved invoice. Owner tests arrive at your own account address; receiving one does not confirm the client address or deliver the production invoice.
After processing, inspect the status. Pending is waiting work; Processing may mean a send is underway or delivery needs investigation; Sent records completed dispatch. Failed needs an error review. Payment and Drive archiving have their own checks, so a sent invoice with an archive error should not be resent just to create a file copy.

Use this page to move from general research into a calmer, more repeatable invoicing process.
Prepare, send, and reconcile the result
1. Make the message match the invoice
Compare invoice number, amount, currency, deadline, and payment reference across the email and PDF. Remove old client names or service periods from reused wording. Avoid typing a fixed total into a reusable message if synced hours or currency conversion could change that total.
2. Test before scheduling becomes due
Open the saved-invoice test attachment and read the message on a small screen. Check recipient spelling in the saved record, then confirm the send date and due date separately. Scheduled time makes the invoice eligible for processing; it does not guarantee inbox arrival at an exact minute.
3. Act on the specific result
For Sent, continue with payment follow-up and archive checks. For Failed, read and resolve the stated cause. If the invoice says delivery needs review and automatic retries stopped, investigate whether the provider accepted the message before arranging another send. This helps avoid duplicate client emails.

Avoid this
Processing can require attention
An uncertain provider result can leave the invoice in Processing with a delivery-review error and automatic retries stopped. Do not assume every Processing invoice is simply waiting or that copying it into a new invoice is a safe retry.
Avoid this
Archive failure does not undo email
Drive sync runs after a successful send and records its own error. Fix the folder or connection and retry eligible archive work. Resending the client invoice is not the recovery step for a missing Drive PDF.
Avoid this
A payment link does not confirm settlement
A hosted link offers a way to pay. It does not by itself synchronize every provider's payment status. Confirm receipts through the supported payment workflow and record the balance before treating the invoice as Paid.
Move from reading about the workflow to running it.
InvoiceAgent is designed for the last mile of getting paid: scheduled invoice delivery, reminder timing, professional PDFs, and send-time FX conversion when global billing is involved.

Questions people usually have before changing the workflow.
Does InvoiceAgent attach the invoice PDF automatically?
Yes. Scheduled dispatch generates the PDF from the invoice record and includes it in the invoice email. Review a saved-invoice test before the scheduled send.
Does Sent mean my client opened the email?
No. Sent records dispatch through the email service. It does not establish that the client opened the message, approved the invoice, or paid.
Should I resend an invoice when Google Drive sync fails?
No. Check the invoice's delivery status first. A Drive archive error can occur after successful email dispatch; recover the archive separately instead of sending another client email.
What does delivery needs review mean?
The send outcome is uncertain or an error occurred after the provider accepted the email. Automatic retries stop. Review the recorded error and provider delivery evidence before attempting another send.
