01 / 07 · Why this matters
A lost receipt costs you twice.
First when you forget to bill the client for materials you fronted. Again at tax time, when you can't prove the deductions you're entitled to.
Loss #1
Unbilled to the client
Materials you fronted and forgot to charge back. 100% out of pocket.
Loss #2
Unprovable at tax time
Fuel, tools, vehicle, meals — deductible only if you can prove them.
