The problem nobody was solving
Before we wrote a line of code, we heard the same complaint from finance teams, agencies, and freelancers: sending the invoice was not the hard part. The hard part started after the invoice went out.
The invoice lived in QuickBooks or another billing tool. The client reply lived in Gmail. The note about a promised payment date lived in Slack. The overdue tracker lived in a spreadsheet. When someone asked why an invoice was still open, the answer had to be pieced together by hand.
That setup falls apart as soon as more than one person touches receivables. One teammate sends a reminder without seeing the last client reply. Another assumes the follow-up already happened. A third inherits the account with no idea what was promised. The invoice record exists, but the working context around it does not.
