Why payment automation is the highest-ROI operational investment for contractors
Contractors are in the business of delivering skilled labor and materials. Every hour spent chasing invoices is an hour not spent running jobs, building relationships, or managing the business. Payment automation turns the billing and collections workflow into a background process — one that runs reliably without human intervention while you focus on the work.
The ROI is measurable. Most contractors see a 15-20% improvement in paid-on-time rate within 60 days of implementing payment automation. For a $2M contractor, that's $300,000-$400,000 in cash flow improvement — money that was always owed to you but sitting in accounts receivable instead of your bank account.
Step 1: Get your invoice data into a single system
The foundation of payment automation is having all your invoices in one place. If you're on QuickBooks, connect it to your collection tool — overdue invoices sync automatically. If you're using ServiceTitan, Jobber, or another field service management platform, check whether it has direct integration or whether CSV export is the path.
For contractors not on any system (paper invoices or spreadsheets), start with a CSV upload. The minimum data required: customer name, mobile phone number, invoice amount, and due date. Add these four fields and you have everything needed to run an automated reminder sequence.
Step 2: Configure your reminder sequence
The optimal reminder sequence for most contractors: SMS on the due date with a payment link, SMS at +7 days ('just checking in'), AI voice call at +14-21 days for still-unpaid invoices, formal email demand at +30 days. Each stage escalates slightly in urgency without becoming aggressive.
Configure your business name and phone number so reminders appear to come from your company. Customize the script tone to match how you'd speak to customers (professional and direct, or warm and relationship-focused, depending on your market). Add any customers you don't want automated to the protected list.
Step 3: Set up your payment infrastructure
Every reminder should include a direct payment link. Connect Stripe to your Surety account, and a unique payment link is generated for each invoice automatically. The customer clicks, pays, and the transaction records against the invoice in real time. No manual reconciliation, no checks to deposit.
For contractors with both residential and commercial customers, Stripe Connect lets you accept payments directly to your connected account at standard Stripe rates. Commercial customers who need to pay by check or ACH can still do so — just note that option in your reminder template.
Step 4: Monitor and iterate
After the first 30 days, review your attribution dashboard. How many invoices were contacted by Remi? What percentage paid within 24 hours of first contact? What percentage are still outstanding? How does payment velocity compare between contacted and uncontacted invoices?
Use this data to tune your sequence. If the day-7 SMS has a low response rate, try adjusting the message. If voice calls at day 14 have high resolution rates, consider moving them earlier. Payment automation is not a 'set it and forget it' system — it improves with iteration based on your specific customer base.
