The problem

Late payments aren’t a billing problem. They’re a follow-up problem.

Most invoices get paid eventually — the delay comes from inconsistent follow-up. A reminder that never went out, a second nudge that got forgotten. Retenva removes the inconsistency entirely.

The platform

One platform for the entire follow-up lifecycle

From the moment an invoice is issued to the second it's paid — every step automated, observable, and under your control.

Automation engine

Sequences that run themselves

Trigger on due dates, set, and re-run on payment status and reminders across intervals — configured once, executed forever.

Trigger: Invoice overdue Wait 1 day → Send email Wait 3 days → Send SMS

Email reminders

Personalised, on-brand emails sent at exactly the cadence you configure.

SMS reminders

Parallel SMS via Twilio with automatic STOP handling and full opt-in compliance.

Real-time sync

Invoice status synced the moment it changes — no stale data, no duplicate sends.

Stops when paid

The sequence cancels the instant Stripe or your ledger confirms payment.

Architecture

Built on an event-driven engine

Every invoice change, payment, and reply is an event. Retenva reacts in real time — reliably, idempotently, and at scale.

Invoice automation

Reminders before due, escalation after

A gentle heads-up before the due date. A firmer nudge after. An SMS escalation when it matters. Every step timed, professional, and on your terms.
