Most failed vendor relationships show warning signs during the sales process, not after delivery starts. Here's what we tell readers to watch for before signing.
Vague answers about team composition
If a vendor won't confirm who specifically will work on your project — names, seniority, tenure at the company — that's a strong signal your work may be handed to whoever is free, not who's qualified.
No process for handling scope change
Every real project's scope shifts. A vendor with no defined change-request process either hasn't run enough projects to hit this problem, or absorbs scope creep by quietly cutting quality.
Reluctance to share reference clients
A healthy vendor can point to multiple clients willing to take a reference call. Hesitation here, especially paired with only very recent case studies, is worth probing directly.
Pricing that's dramatically below market
Unusually low rates are usually paid for later — through junior staffing, high turnover, or corners cut on testing and documentation. Compare quotes against the ranges published in our cost guides before assuming a low bid is simply efficient.
