Choosing a development partner is a bigger decision than most procurement processes treat it as. The wrong fit doesn't just cost money — it costs the months you spend finding out it isn't working, and the rebuild that usually follows. Here's what to actually check before you sign anything.
Ask how they scope work, not just what they charge
Any vendor can give you a number. What matters is how they got there. A company that quotes a fixed price after a single sales call is either padding the estimate heavily to cover the unknowns, or about to come back to you with change orders once the real scope surfaces. Look for a discovery process that breaks the project into concrete pieces — screens, data models, integrations — before a number gets attached to it.
Find out who actually writes the code
Some firms sell you on a lead architect during the pitch, then staff the project with whoever's available once the contract is signed. Ask directly who will be doing the day-to-day development, what their experience is with the specific type of project you're building, and whether that team stays consistent for the length of the engagement.
Check what "communication" actually means in practice
Every company says they communicate well. The useful question is more specific: how often do you see working software, not a status report? A partner running short iterations should be able to show you something functional on a predictable cadence — weekly is common — rather than asking you to trust a Gantt chart until the big reveal at the end.
Confirm code and IP ownership in writing
This should be uncontroversial, but it isn't always clear in a vendor's standard contract. You want explicit language that source code, design files, and infrastructure configuration become your property on payment, with no ongoing dependency on the vendor to access or modify what you paid for. If a company is vague about this, treat it as a serious red flag.
Ask what happens after launch
A good partner can tell you exactly what post-launch support looks like — monitoring, response times for critical bugs, how dependency updates get handled — before you've asked twice. If the answer is vague, that usually means it hasn't been built into their delivery model, and you'll be negotiating it under pressure the first time something breaks in production.
Watch for how they talk about technology choices
Be cautious of a company that pitches the same stack for every project regardless of what you're building. The right technology choice depends on your team's existing skills, your scaling requirements, and your budget — not on what the vendor happens to be most comfortable selling. A team that explains why a particular stack fits your case, and is willing to say when a simpler option would do, is worth more than one reciting a list of buzzwords.
Get specific about pricing models
Fixed-price and time-and-materials both have a place, but they suit different situations. A tightly scoped feature with a clear finish line is a good fit for fixed pricing. An evolving product without a fixed endpoint is usually better served by a retainer model tied to a dedicated team's capacity. A company that only offers one model regardless of project shape is optimizing for their own convenience, not yours.
