The Admin Time-Cost Calculator

Re-typing emailed jobs, double entry into Xero, chasing overdue invoices, the Friday spreadsheet ritual: it all looks free because it never shows up on the P&L. Put rough weekly hours against the four areas below and see what it actually costs a year. Be honest, and use last week, not a good week.

Job intake & quoting Re-typing emailed jobs into the system, chasing missing site details, quotes written from scratch, follow-ups that rely on memory. hrs/wk
Scheduling & job admin Jobs sent by text, calendar and whiteboard updated separately, paper timesheets typed in later, asking around to see if a job is done. hrs/wk
Invoicing & payments Invoices built by hand from job cards, the same job entered twice (job system, then Xero or MYOB), chasing overdue invoices, keying supplier bills. hrs/wk
Reporting & the office The weekly copy-paste into a spreadsheet, "when's the tech coming?" calls, compliance certs assembled job by job, the inbox as the to-do list. hrs/wk
What an admin hour costs you Wages plus on-costs, or your own hourly rate if it's you doing it. $45 is a fair default. $ /hr
Your admin time-cost, per year

Put your hours in above. Most owners who do this honestly land somewhere between 5 and 20 hours a week.
