Most invoice-chasing tools (Chaser, Upflow) are built for enterprise AR teams and priced accordingly. Follow-up Invoices is built for small businesses: upload a CSV or sync from Stripe, and 3 pre-written reminder emails (friendly, firm, final notice) go out automatically — only during business hours you set. Real Stripe payment links, a dashboard that leads with "recovered this month," and 5 languages. Free tier included, paid plans start at $15/mo.
