The workflow, the users and the success measure on one page.
Screens and the data model, a clickable prototype.
Two-week sprints, a working release in each.
Automated tests, acceptance on real data.
Go-live, monitoring and maintenance.
Roicool's custom software development service covers discovery and requirements analysis, fixing the scope, building web apps, AI and API integrations, testing, launch and documentation, and a maintenance agreement. The source code is kept in the client's repository.

Four problems we solve.
Spreadsheets and email fill the gaps.
Data moves between systems by hand.
Customers can't see their order status.
Experiments never reached your processes.
Cases
We connected SESTEK's Webflow forms not straight to the CRM but to a Webflow Cloud app on the site's domain; only this server layer talks to Microsoft Dynamics 365, and the browser never does. The forms are React code components managed from the Designer, on a bilingual CMS whose folder and item slugs are largely translated.

Customer and partner portals, internal operations tools and calculators: web apps where users log in and get things done.

We connect large language models to your CRM, support and content processes: classification, summarization, knowledge assistants that cite sources.

We connect CRM, ERP, website, ad and analytics systems through APIs: no more moving data by hand, just monitored flows with error handling.

Custom software development is the work of designing and building applications, integrations or AI solutions for business processes that off-the-shelf software doesn't cover. The goal is to stop the team working around its tools: data isn't moved by hand, and the process runs in one system.
Not every need calls for custom software; the right choice depends on how specific your process is.
| Situation | Off-the-shelf software | Custom software |
|---|---|---|
| The process is standard in your industry | Usually enough | An unnecessary cost |
| The process is your own and a competitive edge | Hard to adapt | The right choice |
| Several systems need to be connected | Ready-made integrations can fall short | An integration layer is built |
| Customers need their own portal | Limited | A portal that fits your brand |
We first separate what existing tools can solve, and recommend custom software only where it is really needed.
For simple flows, ready-made automation tools may be enough: Make vs n8n vs Zapier.
Custom software often touches customer and company data, so security is handled at the start of the design, not afterwards. We set role-based permissions, store data only where it is needed, log access and plan privacy requirements as part of the scope. After launch we keep dependencies and security updates current, and put a backup and recovery plan in place.
The team uses spreadsheets and email to work around the tools.
Data is moved by hand between the CRM, ERP, website and ad platforms.
Customers should be able to see the status of their quote, order or project themselves.
There have been experiments, but they were never connected to your processes.
Web applications, customer and partner portals, internal operations tools, AI integrations and API integrations between systems. Our focus is software that touches marketing, sales and customer operations.
Fixed scope and price for work whose scope is clear after discovery; a team-per-period model for work with high uncertainty. We spell out the difference between the two in the proposal.
Unless the contract says otherwise, the delivered source code and documentation belong to the client; the code is kept in the client's repository.
Yes. We set up a maintenance agreement for bug fixes, security updates and small improvements.
At the start of the project we decide which data goes to which model provider, whether it is stored, and how personal data is protected; the KVKK (Turkish data protection law) assessment is done with your legal counsel.
