Book Guardian
to-the-minute accounting
Bookkeeping for Auto Repair & Auto Shops — you fix cars, we track the money
Auto shops run on parts mark-up, labour hours, and customer loyalty — but the ones that stall do so because they can't see their true margin job by job. Book Guardian keeps your shop books current, GST/HST-ready, and parts-to-labour accurate at a flat price — so you can stop being your own back-office and get back on the floor. You approve every dollar; your accountant stays for the tax return.
Parts-labour
split & margin
Per-job
costing & profitability
Construction bookkeeping is its own beast. It kills more shops than bad workmanship.
Materials on credit, subs to pay on schedule, retainage sitting in the receivables, change orders
that never got coded, GST/QST or sales tax that has to be exact. Generic bookkeeping drops the ball
here. We build the books around the job — materials, labour, subs, and equipment tagged to the
project they belong to — so you can see which jobs carry the business and which ones quietly lose it.
Does this sound like you? The signs are clear.
You can't tell parts from labour marginacross the month — you're pricing in the dark.
Parts inventory is a guessand shrink or write-offs vanish from the records.
GST/HST is a scrambleevery filing, and you dread the deadline.
You don't know your true hourly costagainst what you bill for labour.
Tech pay & jobs don't tie outand the month-end is a mess to untangle.
Your office or the bookkeeperis buried under it and it's still behind.
If two or more are true, the fix isn't a busier office manager — it's a job-costed system that runs
itself, flat monthly, without a payroll line.
How it works. Hands-free, job-costed, CPA-grade.
