Contractors lose an average of 5-10% of revenue to late payments and unbilled work. The problem is not deadbeat clients - it is invoicing too late, not tracking change orders, and sending invoices that do not accept online payment. The right invoicing tool sends the invoice the moment a milestone completes, accepts credit card and ACH payment directly, and chases overdue invoices automatically.

5 Tips to Get Paid Faster as a Contractor
1. Accept online payments on every invoice. Clients who can pay with one click pay 2-3x faster than those who must write and mail a check.
2. Invoice immediately on milestone completion. Do not batch invoices monthly. Send the invoice the same day the work is done or the milestone is reached.
3. Set up automatic payment reminders. Three-touch sequence: 3 days before due, on due date, and 7 days after. Most late payments are forgotten, not refused.
4. Require deposits before starting work. 25-50% upfront deposit protects against non-payment and filters out unserious clients.
5. Offer early payment discounts on large projects. 2-3% discount for payment within 10 days costs less than the carrying cost of waiting 60+ days.
