How to Procure Custom Machinery

1. Define the requirement in performance terms

Specify the outcome — throughput at defined product characteristics, yield, uptime, changeover time, energy per unit, quality tolerances, footprint and utility limits — rather than dictating a design. Prescriptive design specifications transfer responsibility for performance from the supplier back to you.

2. Technical preparation

Provide representative product samples and data, upstream and downstream interface details, ambient and utility conditions, and the applicable standards (CE, UL, hygienic design, ATEX). Ambiguity here becomes a variation order later.

3. Budget considerations

Budget total cost of ownership: machine, installation, integration, spares package, training, freight, duties, and the engineering hours your own team must contribute. First-of-a-kind machinery should carry a higher contingency than catalogue equipment.

4. Timeline

Custom machinery typically requires 6–14 months from order to site acceptance: design freeze, manufacture, factory acceptance testing, shipping, installation and commissioning.

5. Qualification, tendering and contract structure

Qualify before you compare prices. Reference installations of comparable duty, in-house engineering capability, financial stability, aftersales presence in your region and spare-parts policy should filter the field before commercial evaluation.

• Advance payment secured by an advance-payment guarantee
• Milestones tied to verified progress, not to calendar dates
• Performance bond and retention until SAT completion
• Liquidated damages for delay and for performance shortfall
• Documentation, source code and spare-parts availability commitments

6. Risk management

Principal risks: specification ambiguity, supplier financial failure mid-build, performance shortfall at real product mix, and aftersales absence in your region. All four are managed contractually before signature — not afterwards.

7. Documentation

Specification, tender comparison, qualification evidence, contract with annexes, FAT/SAT protocols, conformity declarations, manuals, spare parts list and training records.

8. Financing and payment security

Letters of credit, ECA-backed buyer credit and supplier credit are all common. Match payment security instruments to the supplier's country risk and to your exposure at each milestone.

9. Acceptance and handover

Run FAT on your product before shipment, then SAT under production conditions for a defined continuous period. Release retention only after sustained performance, not after mechanical completion.
