CLUSTER INVOICES-AUTOMATICALLY-SMALL · 12 ENTRIES · EARLIEST ENTRY 2026-02-07

Automated invoice chasing apps

This cluster consists of web apps that help freelancers and small businesses automatically track and follow up on unpaid invoices by sending reminder emails at set intervals. The dated history before the index start is too thin to read a shape from, as only one dated entry exists. Traction leaders, based on activity signals, are dunnit, invoice-escalator, and StripeCashOps, though all currently show zero stars.

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
