The best vendors choose the customers that treat them well. NP **Nupur Patel**Aug 11, 2021 · 4 min read In the 1970s and 1980s, American carmakers lost ground to Japanese competitors and sent teams to Japan to find out why. Part of the answer was in the supply base. Japanese manufacturers worked within keiretsu, networks of long term supplier relationships built on shared investment, joint development and mutual commitment. Their supplier contracts were often far shorter than American ones, yet quality was higher. The lesson still holds in 2026. Contracts matter, but the relationship around them decides much of the outcome. This guide explains what effective vendor relationship management involves and the practical steps that build relationships vendors want to invest in. Key takeaways - Choosing on price alone often costs more over the life of a relationship - Share goals and plans with key vendors so they can invest alongside you - Honor the contract, especially payment terms, as you expect vendors to - Review performance regularly and fairly, against agreed measures - Segment vendors so the closest relationships go where they matter most ## What is vendor relationship management? Vendor relationship management is the practice of managing how you work with suppliers across the whole relationship, from selection and onboarding through performance, development and renewal or exit. It treats key vendors as partners whose success affects yours, not just as sources of the lowest price. See [vendor relationship management](https://aavenir.com/glossary/vendor-relationship-management/). ## What can the keiretsu model teach? In a keiretsu, each part had an established supplier, and each supplier had a long term relationship with the manufacturer, often supported by financial ties and joint research. Quality improvement practices spread through the network because both sides benefited. When American companies tried to copy the supply chain without the relationships, they did not get the same results. You do not need cross shareholdings to apply the lesson. What matters is long term commitment where it makes sense, shared goals, and investment in a supplier’s capability rather than only in negotiating it down. ## Why is the cheapest vendor not always the best? Price is one factor. Quality, reliability, responsiveness, innovation, financial stability and fit with your values all affect total cost and risk. A vendor chosen only on price may cut corners to protect its margin, need more management, or fail when you need it most. Evaluate on weighted criteria that reflect what matters.

Some organizations hold regular sessions with key suppliers to share strategy and invite ideas. Good vendors appreciate being included and can plan capacity and investment around your needs. ### Honor the contract Respect works both ways. Pay on the agreed terms, meet your own obligations and give notice as the contract requires. Organizations that routinely pay late build a reputation, and the best vendors quietly prioritize other customers. See [increasing supplier payment terms](https://aavenir.com/increasing-supplier-payment-terms-who-pays-the-price/). ### Qualify and review fairly Agree performance measures in the contract, review them on a schedule and discuss results openly. Reviews should recognize good performance as well as gaps, and lead to agreed improvement actions with dates. See [vendor performance review](https://aavenir.com/glossary/vendor-performance-review/). ### Segment your vendors Not every vendor needs a partnership. Classify suppliers by spend, criticality and risk, and invest the most relationship effort in the strategic few. Transactional suppliers need efficient processes; strategic ones need joint planning. See [supplier segmentation](https://aavenir.com/glossary/supplier-segmentation/). ### Make working with you easy Onboarding, invoicing and status queries are where vendors feel friction most. A portal for documents, invoices and status, and a fast, predictable onboarding process, show vendors you value their time. [Onboardingflow](https://aavenir.com/solutions/vendor-onboarding-software/) handles registration, document collection and approval, and [Invoiceflow](https://aavenir.com/solutions/accounts-payable-automation/) gives vendors visibility of invoice status. **See vendor onboarding and collaboration on ServiceNow**We will walk through registration, document collection and approval in Onboardingflow, and invoice status for vendors. Schedule a demo ## How do contracts support the relationship? A good contract sets clear expectations on both sides and gives a fair basis for review. Keep every vendor agreement in one place, extract the commitments on both sides, and track them, so reviews rest on facts rather than impressions. See [Contractflow](https://aavenir.com/solutions/enterprise-contract-management-software/) and [Obligationflow](https://aavenir.com/solutions/contract-obligation-management-software/). ## What do strong vendor relationships deliver? Vendors that trust you bring ideas, priority in shortages, flexibility in a crisis and honest warnings when something is going wrong. Over time they help you innovate and stay competitive, and the best of them will want to be part of your supply base because of how you treat them. ## The bottom line Effective vendor relationships rest on a few habits: choose on value, not price alone, share goals with key vendors, honor the contract as you expect them to, review performance fairly, and make working with you easy. Strong vendors will invest in customers like that. ### In this article - What is vendor relationship management? - What can the keiretsu model teach? - Why is the cheapest vendor not always the best? - How do you build better vendor relationships? - How do contracts support the relationship? - What do strong vendor relationships deliver? **See vendor onboarding on ServiceNow**Registration, documents and approvals in one flow, with Aavenir AI checking what vendors submit.
