DUESPARROW / HOW IT WORKS0401

See who owes you money and write the next reminder.

DueSparrow helps freelancers and small agencies track unpaid invoices. Record payments and promised dates, then prepare a polite message to check and send yourself.

01

Add the invoice and any payments

Enter an invoice or import a list. Record payments you have checked in your accounting records so you can see how much is left.

  • Invoice amount and due date
  • Payments already received
  • The amount the client still owes
02

Note what the client has said

Record when they promised to pay. If there is a question about the bill, keep it on hold while you discuss the issue.

  • Promised payment dates
  • Agreed payments split into parts
  • A separate list for bills being discussed
03

Prepare a reminder and send it yourself

Get a draft using the remaining amount. Read it, send it from your own email and note the client’s response.

  • A polite draft for you to check
  • Notes of your contacts and next dates
  • An eight-week view of expected payments
