Overview

Stop spending hours chasing payments

You run a business, not a collections agency. Let Surety handle the follow-ups while you focus on your work.

AI Calls Your Customers

Remi is an AI voice agent for invoice collection - she calls your overdue customers professionally so you don't have to. No more awkward "where's my money?" conversations.

SMS First, Calls Second

Text reminders go out first - with a one-tap payment link. If they don't respond, the AI calls. Polite, professional, TCPA-compliant.

Protected Client List

Your $400K referral source never gets a robot call. Add any client to the Protected List and they're permanently excluded from all automation - you stay in control.

Attribution Dashboard

See exactly which calls moved money and which invoices paid on their own. Called vs. uncalled payment velocity - so you can prove ROI to yourself.

One-Tap Payment via Stripe

Customers get a secure Stripe payment link. They tap, they pay. Funds go directly to your connected bank account.

QuickBooks Sync

Connect QuickBooks Online and overdue invoices sync automatically - no manual entry. Using QB Desktop? Export to CSV and import in 2 minutes.

FAQ

Frequently asked questions

Common questions from service business owners like you.

Who is Surety built for?

Surety is built for small service businesses: contractors, landscapers, plumbers, cleaners, consultants, and anyone who invoices customers and is tired of chasing late payments manually.

How does it work?

Add your overdue invoices (manually or via CSV), and Surety automatically sends SMS reminders with payment links. If they don't respond, our AI voice agent calls them with a polite, professional reminder. You track everything from your dashboard.

Do I need any special software or integrations?

No mandatory ERP migration is required. Surety can sync overdue invoices from QuickBooks, and you can still use CSV/manual entry as a fallback for quick pilots.

How does the 14-day money-back guarantee work?

We use a 14-day money-back guarantee instead of a free trial. Start on a paid plan, use Surety in real workflows, and if it does not help you collect faster in the first 14 days, we will refund you.

How quickly can I get started?

Under 5 minutes. Sign up, add your first invoice with a customer name, phone number, and amount owed. The first reminder goes out automatically.

Is it compliant? Will my customers be annoyed?

Surety follows TCPA guidelines: we only contact during business hours, respect opt-outs, and keep messages professional. Your customers get a polite reminder, not a harassment campaign.

How do I know Remi actually made a difference, not that they'd have paid anyway?

That's the right question. Your Attribution dashboard shows called vs. uncalled payment velocity: the same invoice aging buckets, one group contacted by Surety and one not. If the called group pays 2-3x faster, that's your delta. We show you the data so you can make the call, not take our word for it.

What if I have a client I absolutely cannot risk calling?

That's exactly what the Protected List is for. Any client you add is permanently excluded from all automated calls and SMS. They never hear from Surety. You control exactly who gets contacted. Period.

What does the 12% fee actually apply to?

The fee applies only to invoices that Remi actually collects. If a customer pays on their own without any Surety contact, there's no fee. You pay 12% of the money Remi moves for you. Nothing more.
