You did the work. You asked the hard questions, checked references, and signed with a firm that said all the right things. Now they're in your codebase, in your Slack, on your standups. So how do you know - quickly - whether you made the right call?
The truth is, the first 30 days tell you almost everything. Vendors and partners behave identically in the sales process. They behave very differently once the contract is signed and the real work begins.
Here's what to watch for.
Week 1: Do They Ask, or Do They Assume?
A vendor opens a ticket and starts building. A partner spends the first few days asking questions you didn't think to answer in the scoping call - about your business model, your users, your three-year plan.
If nobody on the technical side has asked you "why" in the first week, they're executing a spec, not building your company.
Week 2: How Do They Communicate Blockers?
Every project hits friction in week two - an unclear requirement, a third-party API that doesn't behave as documented, a dependency that wasn't accounted for. A vendor quietly works around it or lets the timeline slip without telling you. A partner flags it immediately, explains the tradeoff, and gives you a decision to make.
Look for proactive, specific updates - not vague status reports that say "on track" every week regardless of what's actually happening.
Week 3: Do They Push Back on Scope?
By week three, you'll likely have a new idea, a feature you want added, a pivot you're considering. This is where the distinction becomes obvious. A vendor says yes and quietly extends the timeline. A partner says, "That's going to affect the launch date - here's by how much, and here's what I'd recommend instead."
You're not looking for resistance. You're looking for honesty about tradeoffs.
Week 4: Is Documentation Already Happening?
By the end of the first month, ask to see what's been built - and how it's documented. A rushed vendor relationship produces code with no comments, no README, no architecture notes. A partner relationship produces a system that's explainable from day one, because they're building for the team that inherits it later, not just for the deadline in front of them.
Red Flags to Watch in the First 30 Days
- Status updates that are vague or always positive, even when deadlines slip
- No questions about your business goals - only about technical requirements
- Scope creep accepted silently, with the timeline quietly absorbing the cost
- Code delivered without documentation, tests, or explanation
The Bottom Line
You don't have to wait six months to find out if you hired the right partner. The signals are there in the first 30 days - in how they ask questions, how they communicate problems, and how they handle the inevitable scope changes. Pay attention early, and you'll never be surprised later.
