5 criteria for good suppliers in procurement

5 Criteria For Good Suppliers: High Achievers of Purchasing

Good suppliers tend to share five traits: consistent quality, reliable delivery, fair pricing, clear communication, and financial stability. This guide explains how to weigh each criterion during supplier evaluation, and why the cheapest quote often costs more once you count the rework.

Before we begin reviewing the attributes of good suppliers, let's fly high with fighter jets.

These aircraft have very specific capabilities: they're designed with powerful jet engines, lightweight fuselages, and are able to perform tight maneuvers in a split second. When flying in an airshow, aerial acrobatics are precisely controlled and coordinated in unison with other jets, a visual testament to each pilot's skill. A huge amount of technical expertise, leadership, effective communication, and safety is required.

Now let's pretend these jets never leave the tarmac. How could spectators ever realize their performance potential? The simple answer is they wouldn't. To extend this logic, suppliers should be evaluated by both their pending capabilities and how they perform after they've caught your attention. Avoid limiting your considerations to hypothetical abilities and include expectations of quality, efficiency, and compliance.

In no particular order, here are the top 5 criteria to evaluate when determining the caliber of your suppliers. Keep in mind that high-quality suppliers will enable companies to achieve improved product consistency, lower inventory levels (minus inconvenient out-of-stock issues), lower overall costs, less stress, greater process efficiency, and ultimately a more respectable brand.

1) INFRASTRUCTURE
Suppliers must have the required technical expertise to meet your corporate needs. It's wise to determine each supplier's certification of quality - the International Organization for Standardization provides ISO ratings that will signify a vendor's capabilities. A supplier's facilities, equipment, and financial statements must be in optimal form if they intend to facilitate your organizational success.
2) LEADERSHIP
Suppliers at the front of the pack will employ best management practices without hesitating. All policies & procedures are documented and Business Continuity Planning (BCP) tactics such as risk management & mitigation are well-established. Suppliers with strong leadership typically use the DMAIC approach for optimizing processes - Define, Measure, Analyze, Improve, and Control - which is a technique that can also drive innovation.
3) COMMUNICATION
The ideal supplier will follow market trends while deciphering product quality specifications & appropriate delivery terms with ease. Communicative suppliers are also more likely to adhere to laws and regulations, as they understand the consequences of failing to meet legal requirements.
4) ETHICS & VALUES
When selecting your suppliers it's important to consider their ethics and values for several reasons. This will set the bar for interactions with both customers and the community, which ultimately affects buyer transactions and the quality of materials. Additionally, a supplier that has their ethics and values aligned with yours is easier to trust. Heightened trust creates a stronger buyer-supplier relationship and could even lead to product discounts.
5) HIGH PERFORMANCE
Do your suppliers meet, or exceed, expectations of quality? What about promptness? Have they exhibited compliance with documentation requirements? Can they efficiently resolve conflicts when they arise? All these questions must be answered favorably in order for your suppliers to meet performance criteria.

These five categories will allow companies to identify suppliers that are ready to take off and elevate procurement to its cloud-worthy status.

Frequently Asked Questions

What criteria should you use to evaluate a supplier?
Five criteria cover most situations: consistent quality against specification, reliable delivery against agreed dates, fair and transparent pricing, clear and responsive communication, and financial stability sufficient to meet commitments. Weight them according to what the purchase demands, since a critical production input requires more emphasis on reliability and stability than a routine office purchase does. The important discipline is evaluating both demonstrated performance and claimed capability, because suppliers are generally assessed on what they say during selection and then never reassessed against what they actually delivered.
Why is the cheapest supplier often not the best choice?

Because unit price is only one component of what a purchase costs. Late deliveries create production delays or expedited shipping. Quality variation produces inspection work, rejections and rework. Poor communication consumes buyer time chasing updates. A financially unstable supplier may fail partway through a commitment, leaving you to resource urgently at whatever price is available. Total cost of ownership captures these, though it takes effort to calculate. A practical shortcut is asking what would have to go wrong for the price difference to be erased, and how likely that is with this supplier.

How do you assess a supplier before placing a first order?

Before the first order you are working with claimed capability, so focus on what can be verified. Request references from customers with similar requirements and actually contact them. Review financial information where available. Check certifications and confirm their current status rather than accepting a certificate at face value. Where practical, visit the facility or request samples against your specification. Then start with a smaller trial order that lets you observe delivery, quality and communication before committing significant volume, which is generally more informative than any amount of pre-qualification paperwork.

How do you evaluate a supplier you are already using?

Evaluate existing suppliers on recorded performance rather than impression, which means having delivery dates, quantities received and quality issues captured consistently across the period under review. Useful measures include on-time delivery percentage, order accuracy, quality rejection rate, responsiveness on queries, and the number of invoice or pricing disputes raised. Reviewing these on a set schedule rather than after a problem changes the nature of the conversation, because the discussion is about a trend both sides can see. It also produces the evidence needed if a relationship eventually has to end.
