Hardware planning
How to compare hardware manufacturing quotes
Compare quotes only after matching the revision, quantity, material, finish, inspection, and delivery scope. Separate one-time costs from recurring charges, price missing work, and record exclusions before deciding which offer fits your build.

Build your project brief →1. Establish one quote baseline
Create a dated request package and send corrections to every candidate. Ask suppliers to acknowledge which files and specifications they priced. Resolve conflicts between the CAD model, drawing, and quote configuration before ordering.
- List the drawing and CAD revisions, units, quantity, material grade, and finish.
- Specify the critical dimensions, reporting needs, packaging, and destination.
- Ask suppliers to identify assumptions, substitutions, and excluded operations.
2. Separate the cost buckets
Record recurring part or assembly charges separately from setup, tooling, fixtures, programming, and engineering. Include inspection, finishing, packaging, and freight only where they are priced. Leave an unquoted item unresolved rather than assigning it a zero cost.
- Show one-time charges and whether they recur after a design change.
- Confirm whether tooling storage, maintenance, and transfer are included.
- Record quote validity, payment milestones, and cancellation conditions.
- Request a separate repeat-order quote instead of assuming the pilot unit price will scale.
3. Compare deliverables and timing
An inspected part and a part shipped with a dimensional report are different deliverables. Xometry describes several inspection options, including a build-and-hold first article option for acceptance before the remaining order. That is an example of a service to request, not a default offered by every supplier.
- Specify the features measured, sample quantities, report format, and acceptance owner.
- Ask when lead time begins: order, file approval, material arrival, or another milestone.
- Record dispatch date separately from expected arrival and any customer approval hold.
Worked example: the lower unit price
Illustrative figures, not market prices: Quote A is $40 per part for 50 parts plus $600 setup, totaling $2,600 before freight. Quote B is $48 per part plus $100 setup, totaling $2,500 before freight. If B excludes the required inspection report, its comparable total is still unknown. Request that price before declaring either quote cheaper.
Decision checklist
- Same files, revision, quantity, material, and finish
- One-time and recurring charges separated
- Inspection and acceptance deliverables matched
- Exclusions priced or explicitly unresolved
- Timing, quote validity, and repeat-order assumptions recorded
