Industrial Machinery Due Diligence. The Complete Procurement Guide Before Signing A Purchase Order

The Best Machinery Proposal Isn't Always the Lowest Price 

By now you've learned why engineering capability matters and why buyers, suppliers and operators all have important responsibilities. 

Now comes the most important question. 

How do you compare suppliers objectively before committing hundreds of thousands, or even millions, of dollars? 

Many procurement decisions still focus heavily on capital cost. 

Experienced buyers know that's only one part of the equation. 

The better question is: 

Which supplier presents the lowest overall project risk? 

New to the series? 

This article is Part 3 of the Industrial Machinery Buyer's Guide. 

If you're still researching machinery suppliers, we recommend reading: 

Part 1: Before You Buy Industrial Machinery: Why Qualified Engineering Matters More Than Price, which explains why engineering capability should be assessed before comparing machinery suppliers. 

Part 2: Buying Industrial Machinery? Understand Your Responsibilities Before You Sign the Purchase Order, which explains the responsibilities of importers, suppliers, systems integrators and operators, along with the importance of engineering reviews, Safety Requirements Specifications (SRS) and supplier due diligence. 

If you're ready to compare suppliers and make a purchasing decision, continue with this practical procurement guide. 

Build Your Procurement Team Early 

Successful machinery projects rarely involve procurement alone. 

The most effective purchasing decisions include input from: 

  • Operations 
  • Maintenance 
  • Engineering 
  • Safety 
  • Production 
  • Finance 
  • Procurement 
  • Senior management 

Early collaboration helps identify technical, operational and commercial risks before contracts are signed. 

Compare Engineering Capability Before Comparing Price 

When reviewing quotations, compare more than machine specifications. 

Ask each supplier: 

  • Do they employ qualified engineering professionals? 
  • Are Registered Professional Engineers involved where appropriate? 
  • Is engineering completed in-house? 
  • Are engineering reports produced? 
  • Are calculations and stress analysis completed? 
  • Is design verification undertaken? 
  • Are machinery safety reviews completed? 
  • Is an SRS prepared where appropriate? 

Engineering capability is often the biggest differentiator between suppliers offering similar equipment. 

Evaluate the Engineering Evidence 

Rather than accepting broad statements, ask suppliers to demonstrate their engineering process. 

Look for evidence such as: 

  • Engineering calculations 
  • Structural assessments 
  • Stress analysis 
  • Engineering reports 
  • Design verification 
  • Machinery safety reviews 
  • Compliance assessments 
  • Safety Requirements Specifications 
  • Engineering sign-off 

Engineering evidence provides confidence that decisions are based on sound engineering rather than assumptions. 

Assess Documentation 

Good suppliers provide more than machinery. 

They provide documentation that supports the equipment throughout its lifecycle. 

Request: 

  • Operating manuals 
  • Maintenance manuals 
  • Engineering drawings 
  • Electrical documentation 
  • Risk assessments 
  • SRS documentation where appropriate 
  • Commissioning records 
  • Engineering reports 

Review Insurance 

As part of supplier due diligence, ask for evidence of: 

  • Public Liability Insurance 
  • Product Liability Insurance 

This should form part of every procurement process. 

Consider Total Cost of Ownership 

The purchase price is only one component of the investment. 

Also consider: 

  • Installation 
  • Commissioning 
  • Downtime 
  • Maintenance 
  • Spare parts 
  • Engineering support 
  • Future modifications 
  • Productivity 
  • Reliability 
  • Operational life 

A lower purchase price can become significantly more expensive if engineering issues emerge after installation. 

Download: Engineering & Compliance Due Diligence Checklist 

Use our downloadable checklist to evaluate suppliers before making your purchasing decision. 

The checklist includes: 

  • Supplier capability assessment 
  • Engineering capability review 
  • Compliance questions 
  • Documentation requirements 
  • Insurance verification 
  • Commissioning considerations 
  • Procurement sign-off prompts 

Whether you're investing in a single machine or a complete processing facility, this checklist can help structure your evaluation process. 

Procurement Red Flags 

Investigate further if a supplier: 

  • Cannot identify who completed the engineering. 
  • Cannot provide engineering evidence. 
  • Relies solely on overseas documentation. 
  • Cannot explain their compliance process. 
  • Cannot provide evidence of insurance. 
  • Offers little or no post-commissioning engineering support. 
  • Focuses only on price rather than project outcomes. 

The Final Question 

Before signing any purchase order, ask yourself: 

Am I simply buying machinery... or am I investing in an engineered solution supported throughout its lifecycle? 

The answer may determine the long-term success of your project. 

This is Part 3 of our three-part Industrial Machinery Buyer's Guide. 

By now you've explored: 

Part 1: Before You Buy Industrial Machinery: Why Qualified Engineering Matters More Than Price 

Learned why engineering capability, Registered Professional Engineers and documented engineering processes should be evaluated before comparing machinery on price alone. 

Part 2: Buying Industrial Machinery? Understand Your Responsibilities Before You Sign the Purchase Order 

Explored the responsibilities of importers, suppliers, systems integrators, manufacturers, employers and operators, along with the importance of engineering reviews, Safety Requirements Specifications (SRS) and supplier due diligence.
