QuickBooks bookkeeping for mechanics

Routine services come and go quickly, while an engine rebuild or a restoration can tie up parts, labour and sublet work for much longer. We keep both kinds of work straight in your QuickBooks file, with the big jobs followed from deposit to final invoice.

Workshop jobs, big and small, in QuickBooks

Everyday jobs are followed through to payment, and the larger repairs are tracked as jobs in their own right.

  • Engine rebuilds, gearbox overhauls and restorations kept as projects for the customer, if your plan has the projects feature, so every part and labour line on that vehicle can be reported on together.
  • Deposits taken before parts are ordered for a big job matched to the customer's project, and recorded under your accountant's treatment for customer deposits.
  • Sublet work, such as machining, auto electrical or windscreen jobs sent to another business, recorded as a supplier bill against the vehicle's job and checked against what was recharged on the customer's invoice.
  • Servicing, mechanical repairs and tyre sales given separate classes, if classes are available on your plan, so the reports show which side of the workshop earns its keep.
  • Hoists, diagnostic scanners and tyre machines recorded when they're bought, with the invoice kept on each purchase so your accountant can choose its treatment, and their finance repayments matched to the lender's statements.
  • Waste oil collection, rags, cleaning supplies and other shop consumables kept apart from the parts charged to jobs, so parts costs on each job stay clear.
  • Statements for the bank account, cards and equipment loans reconciled monthly, with each gap followed up, whether it's a payment still clearing, a wrong entry, or a mistake by the bank for you to query.

Mechanics' questions about QuickBooks

Can I follow a big repair from start to finish?
Yes, on a plan that has projects. The rebuild becomes a project under the customer, and the parts bills, sublet work, labour on the invoices and any deposit are added to it. The project's report then shows what the job has earned and cost so far.
How do you record work I send out to another shop?
The other business's invoice goes in as a supplier bill against the vehicle's job. We check it against what you recharged on the customer's invoice and let you know about any sublet that hasn't been passed on.
A customer paid a deposit before I ordered the engine. Where does it go?
We match it to that customer and their project. Your accountant settles how it's carried in the books until the final invoice, and we record it to match.
Can I tell whether tyres are worth the space?
If classes are on your plan, tyre sales and the cost of the tyres can sit in their own class, which a class report puts next to servicing and repairs. Agree which classes to use with your accountant before you begin.
Do I need to change QuickBooks plans for this?
Projects and class tracking aren't part of every QuickBooks plan, so we start by checking what yours includes. If the big jobs or the tyre side would be easier to follow on a different plan, we'll raise it, and you can decide with your accountant whether to switch.
