Frequently asked questions

What does an invoice tracker do?

It records each invoice, client, amount, due date, payment balance and status so you can see what needs attention. An integrated tracker also connects those records to sending and reminders.

Can I track whether a client opened an invoice?

Yes. InvoiceSonic Pro records when an invoice link is viewed, helping you confirm that it reached the client before following up.

Can I track partial payments?

Yes. Record payments against the invoice and keep the remaining balance visible until it is fully settled.

Is the invoice tracker free?

You can create and download an invoice with the free generator. Saved tracking, open status, recurring invoices and automatic reminders are Pro features available during the 7-day trial; a card is required and billing starts unless you cancel.

Know which invoice needs attention next

Keep the original invoice, client, due date and outstanding amount together. Use delivery and view status to guide follow-up, and record confirmed payments against the right invoice.

An opened invoice is not a paid invoice. If the client says payment is on the way, check the payment record before marking it settled or sending another reminder.
