Machine Shop Quotations to Job Cards: Control the Handoff

Manage machine-shop quotations and job cards by carrying the accepted order and specification into approved shop instructions, with explicit revision and change control. The quotation describes the commercial offer; the job packet tells production which approved part, quantity and operations to execute.

An accepted customer purchase order or sales order may sit between those documents. Confirm that handoff in the actual ERP workflow instead of assuming every quotation converts directly into a job card.

Capture the drawing and commercial assumptions

Record the customer, part number, drawing/model reference, revision, quantity, material grade and delivery requirement. Clarify customer-supplied material, outside processing, inspection reports, packaging and any work excluded from the quote. Resolve missing specifications before they become assumptions on the shop floor.

Estimate material, setup, cycle time, tooling/fixtures, outside services, inspection and dispatch on a consistent quantity basis. Retain the source and date of rates. Separate setup effort from per-part effort so a change in order quantity can be reviewed correctly.

ERPNext's quotation documentation illustrates the commercial document. Its work-order documentation covers the production instruction. Keep their purposes and approval states distinct in your own process.

Review the accepted order before releasing work

The operator needs the approved work and inspection instructions, not every internal pricing calculation. Retain the estimate for commercial and cost review while exposing the appropriate production information to each role.

Handle a drawing revision as an explicit change

Consider an illustrative order accepted against drawing Rev B. Its job packet should reference Rev B. If the customer later sends Rev C, record who reviews the change and whether it affects material already bought, parts in progress, outside work, inspection or the delivery commitment.

Do not silently replace the attachment on active work. Obtain the required commercial and technical approval, identify the affected jobs or quantities, and issue the approved instruction to the relevant teams. Retain the old revision and decision history so completed work remains explainable.

Prepare the route and capture actual work

Use the approved material list and operation sequence when preparing the job. ERPNext's BOM documentation gives an example of materials and operations linked to production planning. Verify how your system handles revisions and job-specific changes before release.

Record starts, completions, good quantity, rejection, rework, waiting reasons and outside-process movements against the job or operation. Link the relevant inspections and release decisions. A total produced quantity without its accepted or held status is incomplete information for dispatch.

Compare the estimate with actual records

After the job closes, compare planned and actual material use, setup, operating time, outside cost and approved rework. Keep scope changes separate from estimation errors. A later drawing change should not make the original quotation appear inaccurate without an explanation.

Use that evidence to review the next estimate and process plan. For the commercial document itself, see the sales quotation guide; for execution, use the work-order checklist. The CNC ERP evaluation guide helps turn this handoff into a software demo. Ask Optiwise to trace one accepted revision through its job, inspection and completion records.

Questions from manufacturing teams

Does a quotation always become a job card directly?

No. An accepted purchase order, sales order, production plan or work order may intervene. Confirm the document flow and approval points in the ERP being used.

What belongs on a machine-shop job card?

Include the job/order reference, part and approved revision, quantity, material, operation sequence, required instructions, inspection references and due date. Give each role access to the information needed to perform the work.

What should happen when the drawing changes after work starts?

Review the affected material, WIP, outside work, quality and delivery commitment. Obtain the required approval, issue controlled revised instructions and retain the original revision and change history.
