A custom software development company that stays after launch

A custom software development company designs, builds and maintains software made for one business, rather than selling a product many businesses share. Hashlogics does all three with senior engineers, for enterprises and startups, and stays on after launch under an SLA or a trained handover.

Yes. Single sign-on, role permissions at the data layer and an audit trail are designed in from the first milestone. TrialTriage runs with TOTP multi-factor login and a 23-action audit trail, and we integrate with NetSuite, Salesforce, QuickBooks or whatever ERP and CRM you run.

Yes, when a packaged ERP doesn't fit how you work. We build operations platforms around one shared record, like TomoDomo's coliving platform and PeopleMuster, and we integrate with an existing ERP where one already holds the books.

Yes. The price is fixed per milestone, each with written acceptance criteria, and inside each milestone we work in short iterations you can see. A change in direction re-plans the next milestone rather than running up hours.

Yes. The Blueprint is our consulting step: an engineer reads your systems and data and writes the plan with a fixed price per milestone. It is fixed-fee, credited in full against the build, and if the plan isn't one you'd act on, you don't pay for it.

You do. Source code, data model, infrastructure accounts and documentation are yours in writing before work starts, so your own team or another firm could carry it on.

Whoever built it keeps running it, under an agreed service level, or your team takes it over with documentation and training. That choice is made before the build starts, not after something breaks. The first 2 months of support and maintenance are free, with every build. This is the question we get asked last and it should be asked first, because it is where most custom software quietly dies.

Four things drive the cost. How many systems it must integrate with. The state of your existing data. Whether a security review stands between you and launch. Who owns the thing afterwards. Integration count moves the number most. We publish no price ranges, because a figure quoted before anyone has read your workflow is a guess wearing a decimal point. You get a fixed price after scoping.

Buy it if the process is one everybody runs the same way, such as payroll or email. Build it when the process is how you compete, or when no product on the market will agree with the three systems you already run. Our build vs buy software page walks the decision with a table you can take into a meeting.

Both, at the same standard. An enterprise build starts from an existing stack and a security review. A startup build starts from nothing and has to convince an investor's engineers. Neither gets a discounted bar. Early shortcuts are the most expensive thing a young product can carry.

No. Scoping calls are free. Every build starts with a fixed-fee Blueprint: an engineer reads your real systems and writes the plan, with a fixed price for each milestone rather than a guess. The fee is credited in full against the build, and if the plan isn't one you'd act on, you don't pay for it. That is where we go into an existing codebase to work out what is really in there. Reading someone else's system is engineering, not a sales conversation.

Yes, and most of our systems are both. Shift Link runs a Next.js web application for schedulers and a React Native app for workers in the field. Our web application development and mobile app development pages cover each side in detail.
