Auto Shop Invoicing: Stop Wasting Hours on Paperwork

Auto Shop Invoicing: Stop Wasting Hours on Paperwork


You didn't become a mechanic to do paperwork.


Yet the average shop spends 10-15 hours per week on invoicing, record-keeping, and chasing payments. That's 2-3 hours every working day not spent on cars.


It doesn't have to be this way.


The True Cost of Manual Invoicing


Let's break down what manual invoicing costs you:


Time Spent:

  • Writing up each job: 10-15 minutes
  • Calculating totals: 5 minutes
  • Creating invoice: 10-15 minutes
  • Emailing/printing: 5 minutes
  • Filing records: 5 minutes

  • Total: 35-45 minutes per job


    With 5 jobs per day:

  • Daily: 3+ hours on paperwork
  • Weekly: 15+ hours
  • Monthly: 60+ hours
  • Yearly: 720+ hours = 18 work weeks

  • In Dollars (at $75/hr labor rate):

  • Monthly: $4,500 in lost productivity
  • Yearly: $54,000

  • You're paying yourself $75/hour to do data entry.


    What Modern Invoicing Looks Like

  • Labor time tracks automatically

  • When Done:

  • Tap "Done"

  • Invoice sent before customer leaves
