Invoice Chaser

A written product concept for an AR follow-up tool: connect to Stripe/QuickBooks/FreshBooks, and when an invoice goes past due, run an escalating but human-sounding email cadence in the sender's voice until they pay. No code — this is the idea, the wedge, and the pricing thinking, for $9.

At nine bucks this is a cheap head start on a problem that's real and painfully well-documented: freelancers and agencies genuinely won't send the awkward email, and the tone-first framing is the right insight — the product isn't dunning, it's relationship-preserving dunning. What you're buying is a clear thesis, not a moat, so before you build verify two things: how much of this the invoicing tools already do for free (Stripe and QuickBooks both ship basic reminder sequences, so your differentiation lives entirely in tone, escalation logic, and stopping cleanly on payment), and whether the rev-share pricing is workable — taking a cut of recovered receivables edges toward collections territory and may pull in state debt-collection rules, so flat per-seat is likely the cleaner launch. Upside: the OAuth integrations are well-trodden, a scrappy v1 is a weekend or two, and the AR-aging data
