Custom software, built around how you work.

Custom software development for teams that have outgrown spreadsheets and off-the-shelf tools: internal tools, business apps, dashboards and client portals, shaped around your actual workflow. Zynra is registered in Tarbes, France, and works remotely with clients everywhere.

How we approach it

Most small businesses run on a patchwork: a spreadsheet nobody dares to touch, a SaaS that covers 70% of the need, and someone copying data between them by hand every week. Each workaround costs a few minutes. Together they cost a salary, and they break the day the person who knows how it all fits together is on holiday.

01
Map the real workflow
We start with how your team works today: the spreadsheets, the emails, the double data entry, the steps people skip. The goal is to find the few screens and automations that remove the most manual work.
02
Scope v1 and fix the price
We write down what the first version does and what it doesn't. That scope document is what the fixed price is based on, so you know the cost before a line of code is written.
03
Build in weekly increments
A working preview at the end of every sprint week. Your team clicks through real screens with real data and tells us what's wrong while it's still cheap to change.
04
Rollout and handover
We import your existing data, train the people who'll use the tool, and hand over a documented codebase. Thirty days of support after launch cover the edge cases real use always turns up.

What's included in custom software development

Internal tools & back offices

Admin panels for orders, bookings, stock or planning. The screens your team uses all day, designed to be fast rather than pretty.

Business applications

Software built for one specific job in your company: quotes, job tracking, field reports, approvals. Roles and permissions so everyone sees what they need.

Dashboards & reporting

Your key numbers in one place, pulled from the tools you already use, updated automatically instead of rebuilt by hand every Monday.

Client portals

A private space where your clients log in to follow their project, download documents, sign, pay or send requests, instead of chasing you by email.

Automations

Reminders, document generation, notifications, recurring emails. The repetitive tasks someone does by hand today, run by the software instead.

Integrations

Connections to the services you already pay for, such as payments with Stripe, your accounting or CRM tool, or any service with an API, so data is entered once.

Common questions

Most internal tools and business apps fall into our full web application tier, from €2,500 excl. VAT. Platforms with complex workflows or a mobile app start from €6,000. The final price is fixed in writing after a discovery call, based on the agreed scope.

A focused first version is usually scoped to ship in 4 to 8 weeks, like our MVPs. Bigger platforms take longer. You get the timeline in writing with the quote, and a working preview every week along the way.

Sometimes, yes. If an existing SaaS covers your need at a fair price, we'll tell you. Custom software makes sense when your process is what sets you apart, when you're paying for many tools that don't talk to each other, or when the workarounds cost more than building it.

Yes. We import your existing spreadsheets or exports into the new database as part of the project and check the numbers with you before switching over.

You do. We hand over the repository and documentation, so another team can take it over if needed. After the 30 days of included support, we offer maintenance plans if you want us to keep it running and evolving.

Zynra is registered in Tarbes (Hautes-Pyrénées, France). We work remotely, with video workshops and weekly previews, for clients across France and abroad.
