The invoicing problems
every service business faces
If any of these hit close to home, you're losing time and money that field service invoicing software was designed to fix.
Invoices created 2-3 days after the job are forgotten by customers — payment delay beyond 48 hours drops same-day payment probability from 82% to 31%.
Paper work orders that need to be re-entered at the office cause 11% data-entry errors — wrong line items, wrong totals, disputes with customers.
Manual payment follow-up calls take 35-45 minutes daily — chasing invoices that are 7, 14, and 30 days overdue eats into your billable hours.
Customers dispute charges they don't remember — without job photos, technician notes, and a signed approval attached to the invoice, you lose.
End-of-month invoice creation from memory means you forget billable items — most technicians undercharge by $200-$400/month just from missing add-ons.
Every day without field service invoicing software costs your business real money.

in 4 simple steps
Most teams are fully operational with Fixlify AI invoicing in under one business day.
Job Complete — One Tap to Invoice
When the technician marks a job complete in the mobile app, a draft invoice is auto-created from the job's service codes, parts used, and labor time. They review and send in under 60 seconds.
Customer Pays Online Instantly
The invoice arrives by SMS and email with a secure payment link. Customers pay by card, ACH, or Apple/Google Pay — no account needed. Average time to payment: 14 minutes.
Automatic Payment Reminders
Unpaid invoices trigger an automated reminder sequence: friendly nudge at Day 3, firm reminder at Day 7, and escalation notice at Day 14. Most overdue invoices are recovered by Day 7.
Revenue Auto-Syncs
Every payment automatically updates your revenue dashboard, technician performance reports, and monthly P&L. No manual reconciliation, no accounting re-entry.
How different service businesses
use invoicing
Real results from real businesses across trades. See all 14 industries we serve.
Electrician On-Site Invoicing
A solo electrician was invoicing from his laptop every Sunday evening, often 5-7 days after completing jobs. Customers who paid promptly were the exception. He had $8,400 in outstanding receivables 30+ days overdue.
Cleaning Company Recurring Billing
A cleaning company with 45 recurring clients was manually creating 45 invoices at month-end. 11 clients consistently paid late, requiring follow-up calls that consumed Friday afternoons.
Roofing Deposit and Final Invoice
A roofing contractor needed deposit collection at contract signing and final invoice on completion. Without automation, collecting the 40% deposit before ordering materials was a chase each time.
Flooring Multi-Phase Project Billing
A flooring company billed in phases: materials delivery, installation, and final walk-through. Tracking which customers owed which phase was a spreadsheet nightmare with a 20% error rate.
