    Frequently Asked Questions

    Answers to questions United States clients ask when building custom software development company with DotLinker.

    Off-the-shelf software is built for the average user across many companies. Custom software is designed specifically around your workflows, data, and integrations, so it fits without requiring you to change how you operate.

    Both — custom software development at DotLinker covers web applications, mobile apps, and the APIs and integrations that connect them, chosen based on how your team and customers will actually use the system.

    We regularly build custom software that integrates with or replaces parts of an existing stack, rather than requiring a full rebuild from scratch.

    You get a working team immediately, without the time and cost of hiring, without the overhead of employment when the project scope changes, and with our existing delivery process already in place.

    We provide a dedicated in-house engineering team in Kolkata with daily working hours aligned with United States business hours. We coordinate via Slack, video standups, and structured sprint reports so you get real-time collaboration with zero timezone friction.

    Yes. During initial discovery, we break down your Custom Software requirements into milestones and clear deliverables, providing fixed-scope or flexible sprint estimates tailored to your timeline.
