How to Pick a Software Development Partner: What to Verify Before Signing

Start with proven experience, not the number of logos on the website. Ask to see two or three projects that sit close to your domain and your stack, and then ask whether those engineers are still with the kotlin web development company. A serious vendor will introduce you to the people who would work on your project. Vague answers at this stage usually mean the demo work came from somewhere else.

The contract needs a slower read than the pitch. Three clauses do most of the work: ownership of the code, the NDA, and termination and handover. All the work product has to transfer to you on payment, including source code, designs and infrastructure as code. Look closely at any clause that leaves reusable components outside the transfer, since that is often exactly the piece that locks you in.

Find out how the estimate was built. An honest estimate arrives with the assumptions behind it, a breakdown per feature and an explicit range. A fixed-bid deal only makes sense when the scope is genuinely frozen; otherwise the provider pads the number and you pay seo agency for saas it anyway. A time-and-materials model moves the risk back to the client, so it needs visible weekly reporting and a spending cap.

Process beats headcount. Ask what happens when the scope changes, who writes the acceptance criteria and how testing is organised. A team should be able to demonstrate a live build at the end of each sprint. Acceptance criteria in writing are your only real protection against the it-was-never-in-scope conversation.

Before signing, think about the end of the engagement before it becomes urgent. Insist that the repository sits in your organisation from the first commit, and that the documentation is refreshed in every sprint. A provider confident in its own work accepts it without argument; a long negotiation over it tells you most of what you need to know.
