Why Invoicing & Estimates matters for contractors

Most contractors lose 10-20% of revenue to slow invoicing — drafts that never get sent, work that gets billed three weeks late, and clients who pay even later because they forgot what the work was. Field invoicing collapses days-to-pay by 18+ days for the average contractor.

Common use case

An HVAC tech finishes a Texas service call at 3:47 PM. From the truck, he builds an invoice with refrigerant pounds, equipment serial, EPA technician number, and Texas sales tax pre-applied. Client signs on the phone screen. Stripe payment link sent. Paid by 5:30 PM — same-day, before he's even back to the shop.

What Invoicing & Estimates replaces

QuickBooks back at the office, Word templates with broken formatting, and the dreaded "I'll send the invoice Monday" promise.
