Custom Software Development Company for US and European Businesses

Your team copies the same data between three systems, takes bookings through a tangle of emails and messages, or runs part of the business from a spreadsheet that has outgrown itself. Off-the-shelf tools get you most of the way, then force your process into their shape. And the agencies offering to build something custom rarely show you anything they have built and kept running.

We map how the work actually happens, recommend whether to buy, connect or build, and if building is right, deliver it in milestones you can test. You deal directly with the people writing the code, we choose technology the next team can maintain, and we recommend the system runs in accounts and hosting your business controls.

Buy, when a tool already does the job

If a subscription product covers how you work, it is almost always cheaper to buy it than to build it. We will tell you which one, and stop there.

Connect, when good tools do not talk to each other

Often the problem is the copying between systems, not the systems. A small integration that moves data between the tools you already pay for is usually the cheapest custom software there is.

Build, when the way you work is the advantage

A booking flow your customers prefer to a marketplace's, a tool that removes hours of manual work each week, or data nobody else has. That is where custom software earns its cost.

Time zones

India Standard Time is UTC+5:30 all year, with no daylight saving. That puts us 3.5 to 4.5 hours ahead of Central Europe, 4.5 to 5.5 hours ahead of the UK and 9.5 to 13.5 hours ahead of the mainland US. European mornings overlap our afternoons. With US teams we agree a regular call window at the start and keep everything else in writing, so work never waits on a meeting.

How you see progress

As installable test builds and private staging sites rather than slides: TestFlight for iPhone and Mac, Google Play testing tracks for Android, test builds for desktop software and a staging site for web projects. Decisions are written down, so nobody has to remember what was agreed on a call.

Scope, quote and changes

Before work starts you get a written scope and a fixed quote, with milestones agreed alongside it. If the scope changes, we price the change before doing it, so the final invoice holds no surprises.

Ownership and accounts

The contract sets out who owns the code, the designs and the store listings. We recommend that everything lives in accounts your business controls from the first day: your Apple and Google developer accounts, your code repository and your hosting.

Privacy law

If your product offers goods or services to people in the EU or UK, or monitors their behaviour, the GDPR and UK GDPR generally apply. Where we process that data on your behalf we do it under a written data processing agreement, with Standard Contractual Clauses, or the UK equivalent, covering access from India. US state laws such as California's CCPA may apply too. We collect as little as the product needs: Kapy Notes keeps notes on the device unless the user turns on end-to-end encrypted sync.

Accessibility

The European Accessibility Act has applied since 28 June 2025 to many consumer products and services sold in the EU, including e-commerce and banking. In the US, ADA claims regularly cover websites and apps. We plan for screen readers, larger text and colour contrast from the first design, because retrofitting them late costs far more.

Users and roles

A tool for one team with one way of working is simpler than a system with customers, staff and managers who each see and do different things.

Integrations

Every system the software talks to, whether payments, calendars, a CRM or an accounting package, needs building, testing and keeping working when the other side changes.

Existing data

Moving years of records out of spreadsheets or an old system takes cleaning and checking, and it is often the part people underestimate.

Security and compliance

Personal data, payments and regulated industries bring extra design, testing and paperwork, including GDPR obligations for anyone in the EU or UK.

Platforms

A web application reachable from any browser costs less than the same system with dedicated desktop and mobile apps, though some work genuinely needs them.

Life after launch

Hosting, security updates, backups and small improvements continue after release. We agree that rhythm with you before launch rather than after.

A defined project

A new app, a rebuild or a piece of software with a clear goal. We scope it, quote a fixed price and deliver it in milestones you can test, through to the store release or the handover.

A product that keeps shipping

Most software needs a steady rhythm after launch: fixes, new operating system versions and new features. We plan releases with you and keep a changelog your users can read, as Strata, Maintainly and Kapy Notes each do.

Taking over an existing product

If another team built your app or software, we start by reviewing the code, the build setup and the accounts it depends on, then tell you plainly what to keep, fix or rebuild before you commit to anything.
