Flat fee vs revenue share: the real cost of dunning tools

By Palash Sarker, Founder & Software Architect, Revenue Recovery Labs4 min read Verified by RRLabs

The short answer

Why percentage pricing gets expensive exactly when recovery starts working.

A 9% cut on $40k recovered monthly is $3,600 — 7x the top RRLabs tier. Flat pricing means cost per recovered dollar falls as volume grows. RRLabs charges $100, $250 or $500 per month with no revenue share.

Working through it

Involuntary churn behaves differently from voluntary churn: there is no objection to overcome, only a payment detail and a message that has to arrive.

That means the operating levers are timing, channel and clarity — in that order. Copy polish is the last few points, not the first.
