Open-source freelancer invoicing tools

This cluster consists of open-source invoicing applications for freelancers and small businesses, offering PDF invoice creation and client management. The dated history shows two entries in 2013, then a long pause, followed by several entries from 2025 through mid-2026. Traction is led by Tallyo with 15 stars, while other members have minimal star activity.

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.
