Features
One focused tool for the part freelancers hate most.
Collectli does not try to be accounting software. It stays on the overdue workflow: what is unpaid, who needs a reminder, and what has already been sent.
Reminders that send themselves
Set your cadence once. Collectli handles every follow-up from day 0 to day 7 and beyond — no manual sending, no forgotten clients.
See exactly who owes what, right now
One clean table. Every invoice, every status, every next action. No noise, no bloat.
Upgrade when you're ready, not before
Free keeps you moving. Pro unlocks unlimited invoices and Polar billing when your volume demands it.
Workflow
Add the invoice. Collectli does the awkward part.
The workflow stays short on purpose: log the invoice once, let the reminders go out, then close it the moment payment lands.
01
Create and track invoices
Add the invoice number, client email, amount, and due date. That's it. Collectli takes it from there.
02
Watch overdue risk rise
The dashboard surfaces what's unpaid and flags invoices that have crossed each reminder threshold.
03
Send polished reminders
Reminder emails go out automatically — branded subject lines, clean signatures, zero awkwardness.
04
Close invoices fast
Mark as paid, archive the reminder history, move on. No overdue invoice lingers in the queue.
Final CTA
You did the work. Now get paid for it.
Collectli is intentionally narrow. No OCR, no PDFs, no bookkeeping detours. Just reminders that go out and invoices that get closed.
