The work is done. The invoice is out. The money isn't there. Knock Knock sends polite, persistent payment reminders via SMS โ in your voice, not a collections robot. It stops the moment they pay.
Text your Knock Knock number: "Mike Johnson owes $450, roof repair, 2085551234." That's it. Knock Knock parses the name, amount, job, and customer phone instantly.
Day 1, day 5, day 14, day 30 โ each message escalating slightly in urgency but never aggressive. Claude writes them to sound like you, not a collections agency.
Text "PAID 2085551234" and all reminders stop immediately. If they reply with a question or dispute, Claude handles it โ and alerts you if it needs your attention.
Claude writes every reminder fresh โ using the customer's name, the specific job, and the right tone for where they are in the sequence. Professional, human, effective.
When customers reply โ with excuses, hardship stories, or disputes โ Claude responds appropriately and escalates to you when needed. You stay out of it until it matters.
PAID to close an invoice. LIST to see what's open. That's it. No app to learn, no dashboard to log into. It all works via the SMS number you already have.
Day 1 is friendly. Day 30 is firm. But Knock Knock never threatens, never mentions credit bureaus, never damages the relationship you worked to build.
One flat price, no per-invoice fees. Whether you have 3 open invoices or 50, Knock Knock tracks them all without you chasing anyone manually.
If a customer gets upset or mentions a dispute, you get an SMS alert with the full context. You step in exactly when you're needed โ not before.
