Tolga EGE

Custom Software Development

Software tailored exclusively to your business processes — end-to-end from discovery to launch.

Custom software development kicks in when your business processes can't be solved with standard package software (SAP, Microsoft, off-the-shelf CRMs); it's software production designed from scratch. Instead of using a SaaS with established product-market fit, you build a custom tool that scales to your processes.

As Tolga Ege we manage all steps in custom software development from discovery call to process mapping, data modeling, architectural design, development, testing and go-live. We use modern stack (Next.js, Node.js, Laravel, PostgreSQL) and DevOps (Docker, CI/CD).

Custom software may seem high in initial investment compared to packages; however, the absence of license fees, 100% process fit and source code ownership make ROI high in the long term.

When Is Custom Software the Right Choice?

When off-the-shelf SaaS doesn't fit your processes, when you have differentiating internal processes, when data control is critical due to regulation/security, when license costs become expensive long-term — custom is the right choice.

Process Mapping and Requirements Analysis

Current workflow mapping (BPMN), user roles and permissions, integration needs (ERP, accounting, e-invoice), reporting requirements are determined in discovery phase.

Architectural Decisions

Monolithic vs microservice, multi-tenant vs single-customer, on-premise vs cloud, which database, which auth system — all decided at project start.

Ownership and Maintenance

All source code transferred to your Git repository. No lock-in; transferable to independent teams anytime. Regular updates with monthly maintenance packages.

Cost and ROI Calculation

Initial investment: $10K-100K range. ROI achieved in 2-4 years compared to off-the-shelf; absence of license costs and full process fit increase operational efficiency.
