Should you automate invoicing? A five-minute way to work out what it's costing you
Most businesses underestimate what manual invoicing costs because the time is spread thin. Here's a quick calculation and what automation realistically saves.
Nobody puts "typing invoices" in the budget. It's ten minutes here, a Friday afternoon there, a month-end that takes two days. Spread thin, it looks like nothing. Add it up and it's usually a part-time salary.
The five-minute calculation
Grab last month's numbers and be honest.
- Invoices sent last month: ___
- Minutes per invoice (finding the details, typing, checking, sending): ___ (most businesses land at 8–15 minutes)
- Statements or reminders sent: ___ × minutes each: ___
- Time fixing invoice errors (wrong amount, wrong customer, missing PO): ___ minutes
- Chasing overdue invoices: ___ minutes
Total the minutes. Divide by 60. Multiply by what that person's hour costs the business (wages plus on-costs, or your own hourly rate if it's you). Multiply by 12.
For a business sending 150 invoices a month at 12 minutes each, with a few hours of statements and chasing, that's roughly 40 hours a month — around $25,000 a year at a modest loaded rate. And that's before counting cash-flow cost from late chasing.
What automation actually changes
Invoices generate themselves from the thing that already exists — the accepted quote, the completed job, the delivered order. Nobody types the customer's address again. Errors drop because there's no re-keying.
Statements go out on a schedule. The 1st of the month, every account customer, automatically. The office manager stops building them by hand.
Reminders fire without you. A polite nudge three days before due, another on the due date, a firmer one a week after. Written in your tone, sent by the system. Overdue days fall because the chasing is consistent.
Your bookkeeper still gets Xero or MYOB. The tool hands each invoice to your accounting system; nothing about your accounts changes.
When it isn't worth it
- You send fewer than about 30 invoices a month and they're all different. Do them in Xero and move on.
- Your invoices come from a system that already automates them (some job-management platforms do this well). Check before building.
- The real problem is that jobs aren't being recorded, so there's nothing to generate the invoice from. Fix the job tracker first — often that's the same project.
What it costs
A custom invoice and statement generator built from your jobs or orders is typically $1,400–$4,200, plus a small monthly fee if we host it. Against the calculation above, most businesses are ahead inside the first year, often the first quarter.
A practical first step
Send us last month's numbers from the calculation and a sample invoice. We'll tell you in one email whether automation is worth it for you — and if the honest answer is "just use Xero properly", that's what we'll say.
