Xero bookkeeping for mechanics

In a workshop, each job card becomes an invoice, the parts on it were often bought on a trade account, and fleet customers pay on terms rather than at the counter. We keep that chain in order in your Xero file, from invoice to payment and from supplier statement to the parts on each job.

From job card to paid invoice, in Xero

Each job is traced from the workshop system into Xero, and each parts purchase from the trade counter to the supplier's statement.

  • Job cards from your workshop system turned into Xero invoices, with labour and parts on their own lines
  • Card payments taken at pick-up matched to the invoices they settle
  • Parts bought on trade accounts entered as bills, then ticked off against the supplier's statement before it's paid
  • Credits for returned and warranty parts applied to the bills they offset, so they come off the next payment
  • Shelf stock of parts held as tracked inventory items in Xero, apart from parts ordered in for a particular job
  • Fleet and account customers' invoices followed through to payment, with an aged receivables report each month showing who owes what
  • The workshop's bank, card and equipment finance accounts reconciled to each statement, with any differences explained

Not included

Quoting jobs and ordering parts stay in your workshop system. We work from the job cards and supplier invoices it holds.

Questions workshop owners ask about Xero

Can you work from my workshop management software?
Yes. We use the job cards and reports it produces to raise invoices and record payments in Xero, so the workshop keeps running the way it does now.
How do you keep on top of fleet customers who pay on account?
Every invoice to a fleet or business customer is held against that customer in Xero. Run the aged receivables report and you see each customer's balance and how long it has been outstanding. We send you that list each month so slow payers can be followed up early.
My parts supplier's statement doesn't match my bills. What do you do?
We go through the statement against the bills and credits in Xero and list each difference, such as an invoice we haven't received, a credit not yet applied or a payment the supplier hasn't recorded. Anything that needs the supplier's input is passed to you to raise with them.
Should parts be tracked as stock in Xero?
Shelf parts can be kept as tracked inventory items, which record their quantity and cost as you buy them. Which parts to track that way, and which to record straight against the job, is a decision to make with your accountant.
Do you need to be at the workshop?
No. We work in your Xero file, for workshops anywhere in Australia, from the job cards, supplier invoices and bank feeds you share with us.
