HOW DUESPARROW WORKS

Know what is owed.
Know who to ask.

For freelancers and small agencies that send invoices and need a simple way to keep track of late payments.

01 / ADD THE INVOICE

Check how much is left to pay.

Add an unpaid invoice and any payments already received. Check the amount against your accounting records.

02 / NOTE WHAT THE CLIENT SAID

Did they promise to pay on Friday?

Save the promised date. If the client has a question about the bill, put the reminder on hold while you discuss it.

03 / SEND A REMINDER

Write a polite payment message.

Review the draft and send it from your own email. Save the client’s reply and when you plan to follow up.

What does DueSparrow do?

It helps you keep track of money clients still owe you. For example, if a client has paid $200 of a $500 invoice, you can see the $300 left, note when they promised to pay, and prepare a reminder.

Does it send messages or collect the money for me?

No. It prepares a message for you to review and send. You record payments after checking your accounting records. It does not issue invoices, connect to your bank or take client payments.

What if the client promised to pay, or has a question about the bill?

A future payment promise or a disputed bill keeps the invoice out of the normal reminder list. Wait for the agreed date or discuss the issue, then update the record.
