Custom web application development
Customer portals, custom CRM systems, internal tools and SaaS products, built around how your business actually works.
StackTypeScript, React and Go for the web and back end; REST and GraphQL for integrations.
What we build
Customer portal development
A personal account where your clients see orders, documents, invoices and statuses, and stop asking your team the same questions by email.
Custom CRM development
A CRM that follows your sales and service process instead of forcing the process into a ready-made product. Pipelines, roles, reports and integrations with the tools you already use.
Internal tools and dashboards
Back-office systems for orders, inventory, scheduling or dispatch that replace spreadsheets and manual copying between programs.
SaaS product development
A web product you sell by subscription: workspaces for each client, roles, billing integration and an admin panel. Our own platform, Octan Tech, is built this way.
How we work
Estimate in one business day
Send a short brief. A developer replies with a budget and timeline estimate within one business day, so you can compare offers on facts.
Two-week stages with a demo
We build in two-week stages. After each stage you see a working result, not a status report, and we agree on the next stage together.
Source code and docs are yours
You receive the source code, access to all services and documentation together with the project. Another team can pick it up at any time.
Support after launch
After launch we can keep the application running: monitoring, fixes and new features.

How much does custom web application development cost?
It depends on the scope: the number of roles, screens, integrations and how complex the business rules are. After a short brief we send a budget and timeline estimate within one business day.
How much does a custom CRM cost compared with a ready-made one?
A ready-made CRM is cheaper to start, but you pay for licences and adapt your process to the product. A custom CRM costs more upfront and fits your process exactly. We help you decide honestly, including when an off-the-shelf CRM with a few integrations is enough.
What is custom CRM development?
Building a CRM around your own sales and service process: your stages, roles, documents and reports, connected to your accounting system, telephony and messengers.
What is SaaS development?
Developing software that customers use in the browser by subscription. Beyond features, it needs separate data for each client, roles, billing and reliable updates without downtime.
Who owns the code?
You do. Source code, access and documentation are handed over with the project.
