Due Note — invoice follow-up desk

Chasing a payment is delicate. A small team needs a clear view of what is due and a reminder that sounds like a person wrote it.

Due Note brings balances, part payments, overdue items and next reminder dates into one view. It prepares an editable follow-up for the owner to check and send from their own email. The app never sends a message.

I built this self-directed sample in Lovable with fictional records. It covers part payments, paused invoices, follow-up notes and CSV export. I added safeguards for storage failures and changes made in another tab.
