The Salesperson Was Trustworthy. The Supplier Was Not
Sylvia Luchian
Founder & Head of Procurement Practice
The 2025 Edelman Trust Barometer identified a critical shift in how trust operates: trust has moved from institutions to personal networks.1 Your colleague's recommendation carries more weight than the vendor's published testimonials. The sales representative you have met has more credibility than the contract your lawyers reviewed. This is not a problem until you are six months into a contract and the sales representative has moved on to their next account.
The gap between the trust you built with a salesperson and the trust you should have in the supplier organisation is one of the most common and most expensive procurement mistakes a business can make.
This is worth understanding clearly because it’s not a criticism of salespeople. The modern sales process is designed to establish personal rapport, demonstrate expertise, and create a sense of shared interest between buyer and seller. Done well, it’s genuinely useful. It helps buyers understand what they are considering and surfaces questions that formal documentation would never raise.
The problem is that personal trust in a salesperson is not transferable to the organisation they represent. The salesperson who was responsive, transparent, and deeply knowledgeable about your specific situation may have no influence over the delivery team, the account management team, or the billing department.
Procurement exists to close that gap. A proper procurement process doesn’t just evaluate the sales pitch. It evaluates the organisation. It checks references from existing customers who are past the honeymoon period. It asks what happens when something goes wrong and who you call. It tests the delivery capability, not just the sales capability.
Key Takeaway: Trust the person you have built a relationship with. Verify the organisation they represent. Those are two separate evaluations and both are required.
Most businesses approach vendor reference checks as a formality. You call the names provided by the vendor. You ask three questions. You hear positive things because the vendor has pre-selected references who will say positive things. You proceed. That’s not a reference check. That’s a confirmation exercise.
A real reference check asks questions the vendor did not anticipate. It speaks to customers who have been through the full contract cycle, including renewals and disputes. The 2026 Edelman Trust Barometer is relevant here: trust has retreated to personal networks.2 A reference from someone in your industry who you know personally is worth ten times the pre-selected reference on the vendor's approved list. Build your own reference network. Use it.
Key Takeaway: Reference checks from pre-selected vendor contacts tell you what the vendor wants you to believe. References from your own network tell you what you need to know. Invest in building the second kind.
After the contract is signed, the first ninety days of the supplier relationship are the most valuable intelligence you will collect about whether your procurement decision was right. This is when the transition happens from sales mode to delivery mode. The responsiveness changes. The team changes. The level of attention changes.
If you are not structured enough to notice and document those changes, you will miss the signals that tell you whether you have a high-trust supplier relationship or a low-trust transaction dressed up in a long-term contract.
Build a ninety-day onboarding review into every significant supplier engagement. Document what was promised. Measure what was delivered. Have the conversation early, before patterns calcify into problems.
Key Takeaway: The salesperson built trust in the buying process. The onboarding period tests whether that trust was warranted. If you are not reviewing performance in the first ninety days, you are not managing a supplier relationship. You are hoping.
The practical solution to the personal-trust-versus-organisational-trust gap is to make both evaluations explicit in your procurement process. Evaluate the salesperson's knowledge and engagement as an indicator of the organisation's culture. Evaluate the organisation's track record, financial stability, staff retention, and delivery methodology as indicators of what you will actually experience post-signature.
A high-performing salesperson can represent a poorly organised delivery function. A less charismatic salesperson can represent an organisation with extraordinary operational rigour. Your procurement process should be designed to find out which one you are actually dealing with.
Key Takeaway: The sales pitch tells you what the vendor wants to be. The reference checks, the delivery methodology, and the onboarding period tell you what the vendor actually is. Design your procurement process to find out both.

Procurement is trust brokering in commercial form. When done properly, it creates the conditions under which buyers and suppliers can exchange value with confidence.
Small and specialist suppliers are operating in a more economically precarious environment than three years ago. Their costs have risen. Margins have compressed.
When a vendor relationship goes wrong, it rarely feels like a commercial dispute. It feels like a betrayal. You were promised something.
