Bookkeeping for machine shops
A machining order consumes stock, setup time, outside finishing and sometimes rework before parts ship. Deposits bring in cash before final margin is known. Connect direct costs to the work order so completed jobs, work in process and shipments still waiting for billing remain separate. Mispar organizes the agreed monthly bookkeeping in your QuickBooks or Xero file. Plans start at $229/mo.
Best for: Independent precision machining and job shops producing parts to customer orders.

Shipped not billed
Where machine shop books usually go wrong
- Job costs lumped together, so a profitable part and a money-losing part look alike.
- Material bought for several jobs on one invoice with no job coding.
- Machine purchases and financing recorded as expenses instead of equipment and debt.
- Outside processing like plating or heat treat not tied to the job it belongs to.
- Setup and programming time ignored when comparing quote to actual.
What the books need to show
Industry-specific accounts and categorization, with the reporting scope agreed before work starts.
Order revenue
Match deposits, progress billing and final invoices to purchase orders and shipment records.
Material use
Connect stock purchases, issues and scrap records to jobs under the accountant-approved inventory policy.
Setup and run labor
Separate setup from production hours where time records support it. Short runs should show preparation cost.
Outside processing
Assign heat treatment, plating and outsourced inspection to the work order that used them.
Tooling and machines
Separate consumable tools, repairs, leases and equipment purchases with asset-review documents.
Work in process
Review open jobs and rework with operations. Paid supplier bills alone do not prove completion.
Reports a machine shop can use
- Job profit comparing quoted price with actual material, labor and outside processing.
- Machine and equipment list with loan balances and monthly payments.
- Work in progress and unbilled jobs at month end.
- Customer concentration, showing how much income depends on your top few accounts.
A simple, predictable process
From kickoff to your first clean close, here is exactly what happens.
Start from the operating records
Review purchase orders, work orders, time logs, material issues and shipments. Confirm the financial exports and references available before agreeing scope.
Agree the account mapping
Set categories for open work orders, outside processing, setup labor. Confirm inventory, advance-payment and asset policies with your accountant where needed.
Reconcile the activity
Check completed shipments against work-order billing. Match bank and card activity to the supporting records and keep unresolved differences on an exceptions list.
Close with open items visible
Deliver the agreed monthly statements and review missing documents, unpaid balances and unresolved items. Tax, legal and operational decisions remain with the relevant advisers.
Illustrative example
A short run looks profitable until its heat-treatment bill is attached to the work order. The job view now includes a direct cost previously hidden in a general supplier category. This is an illustration of the method, not a customer case or a guarantee.
Machine Shops bookkeeping — your questions
Can setup hours be separated from machine run hours?
Yes, when the shop records both against consistent work-order codes.
How are outside finishing costs attached to a parts order?
Use the work-order reference on supplier bills or receiving records. Unmatched costs stay on the exception list.
Can bank transactions alone give exact part costs?
No. Useful costing also needs quantities, time, materials and an agreed overhead method.
How do open machining jobs affect the close?
Review them with operations and apply the accountant-approved work-in-process policy rather than guessing from cash movements.
Can you track profit by job?
Yes. Material, labor and outside work are coded to each job so the margin is visible while the next quote is being written.
What affects the bookkeeping quote for machine shops?
Plans start at $229/mo. Transaction volume, account count and the records and reporting needed determine the agreed scope and final quote. Catch-up work is discussed separately.
