Stop re-typing job details into invoices and QuickBooks
The work ended at 5. The typing starts at 8. Job notes get copied into an invoice, the invoice gets copied into QuickBooks, and somewhere in there a part or an hour goes missing and you eat the cost.
Why this costs more than the time
Typing an invoice by hand at the end of a long day does two expensive things. It delays the invoice, which delays the payment. And it drops line items - the extra fitting, the second trip, the forty minutes of diagnostics. Those are pure margin walking out the door.
What the fix looks like
The job details you already captured - customer, address, what was done, parts, hours - move into the invoice on their own. You review it, you send it. Same numbers, no second typing. If you use QuickBooks, the invoice lands there too instead of being re-entered a third time.
Get paid sooner
Once invoices go out the same day, you can add the quiet part: an automatic reminder if it is still unpaid after a week. No awkward phone call, no chasing. Most owners see the gap between finishing a job and getting paid shrink by days.
How to start
Write down exactly what you do tonight after the last job - what you open, what you copy, where you type it. That description is enough for me to build the first version.
