Automated multi-channel follow-ups via WhatsApp, Email & SMS —
powered by AI that knows how to recover your money professionally.
55% of all B2B invoiced sales in the U.S. are currently overdue. For SaaS companies, failed payment recovery alone costs 9% of ARR. That's not a rounding error — it's a growth killer.
56% of U.S. small businesses are currently owed money. Agencies managing 20+ client invoices can't afford to manually chase each one — and over half must delay hiring or expansion because of it.
Your "friendly reminder" competes with 147 other unread emails. Meanwhile, WhatsApp sits at a 98% open rate. You're using the wrong channel.
Whether you're recovering failed SaaS payments, chasing agency invoices, or getting paid as a freelancer — ProposalCloser adapts to your workflow.
Failed payments silently kill MRR. ProposalCloser's dunning automation catches failed charges before they become churned customers — using WhatsApp and email sequences that actually get opened.
Managing multiple client projects means dozens of outstanding invoices at any time. ProposalCloser handles the follow-ups with professional, escalating reminders — so your team focuses on delivering great work, not chasing payments.
You delivered the project. You sent the invoice. Now silence. ProposalCloser sends perfectly-timed WhatsApp & email reminders so you get paid without writing a single follow-up message.
