The brief
Freelancers lose real money to un-sent and un-chased invoices. Ledgerline's bet: make the entire loop — issue, remind, reconcile — automatic enough that the user's only job is doing the work.
The build
- Recurring invoice engine with timezone-aware scheduling and pro-rating.
- Polite, escalating payment reminders with per-client tone settings (from "gentle nudge" to "final notice").
- PDF generation with a template system; every invoice is archived immutably for audit trails.
- Year-end export bundles income, fees, and VAT into an accountant-ready package.
Transmission log
- Beta users reported invoices paid 9 days faster on average.
- Reminder emails achieve a 61% open rate — politeness engineering works.
