# Custom Software Development > We build custom software: backend, integrations with your internal systems, proprietary APIs and admin panels built for your business. - Source: https://maxdev.ro/en/services/software-development/ - Romanian version: https://maxdev.ro/servicii/dezvoltare-software/ - Site index for AI: https://maxdev.ro/llms.txt --- **Software built around the exact logic of your business.** We design and build custom software end to end: backend, integrations with your internal systems, proprietary APIs and admin panels built for your process, not for a generic plugin. From automating a process that today runs in a spreadsheet, to a platform that connects ERP, invoicing and sales into a single flow. ## It does not matter how specific the problem is. Maybe you have a process that still runs manually, in a spreadsheet or on paper. Maybe you need to connect two systems that were never meant to talk to each other. Maybe you are looking for a module no plugin offers. In every case, we write the code that is missing. **[Automating internal processes](https://maxdev.ro/en/services/ai-automation/)** We replace manual workflows built on spreadsheets, email or paper with applications that run on their own, without depending on someone copying data from one place to another. **[Integration with existing internal systems](https://maxdev.ro/en/services/api-integration/)** We connect the new software with the ERP, CRM or other applications you already use, through an API, so data flows automatically between them. **Proprietary APIs** We build secure, documented APIs so other applications or partners can safely connect to your data. **Custom admin panels** Interfaces built for your team, not generic ones: exactly the data and actions you need, without menus designed for developers. **Complex business rules** Pricing, discounts, commissions or approval flows that do not fit into a standard plugin become tested, predictable code. **Bidirectional sync between systems** Data that flows automatically in both directions, in real time, without manual spreadsheet exports and without the risk of systems falling out of sync. **Modules that do not exist as a plugin** Where the market does not offer a ready made solution, we write code from scratch, sized exactly for the problem you are solving. **Migration from legacy systems** We take the logic out of a legacy system, document it and rebuild it on a modern architecture, without losing your historical data. **Scalable architecture from day one** We design the system to withstand growth, not just to work correctly at launch, so a full rebuild is not needed a year in. **Accounts, roles and permissions** Fine grained control over who can see and who can change each part of the application, by department or by user type. **Custom reports and dashboards** Views built around the decisions you actually make, using your real data, not generic charts with no relation to your process. **Ongoing support and development** The application grows with your business: we add new modules or integrations without rebuilding what already works. ## What a custom software project includes. We do not just ship code. Every piece is designed to integrate with the rest of your business and to hold up over time, not just at the demo. DISCOVERY & ARCHITECTURE ### We start from the real process, not from a template. We analyze how the process works today, manually or inside a legacy system, and design the application architecture around it, not the other way around. We map the current data flow and the decisions behind it We choose the right architecture for the volume and speed you need We document technical decisions so your team understands the system BACKEND & BUSINESS LOGIC ### Business logic written exactly to your rules. Pricing, discounts, approvals, calculations: the complex rules of your business become tested code, not fragile formulas in a spreadsheet. Pricing and discount rules per client or per volume Approval flows involving multiple roles Validations and calculations that do not depend on manual work INTEGRATIONS & SYNC ### Your systems start talking to each other. We connect the new application to your ERP, CRM, invoicing or any other internal system, through a custom API where no ready made connector exists. Bidirectional data sync between systems Webhooks and real time events Authentication and security on every integration ADMIN PANEL & ROLES ### An interface built for your team, not for developers. We build the admin panel around the tasks your team performs every day, with clear roles and permissions for each type of user. Roles and permissions separated by department Reports and dashboards with the data that actually matters Documentation and walkthroughs, so your team knows exactly how to use it ## Companies that chose us as their technology partner.

Code written specifically for your process, not a generic product you just configure. It makes sense when a plugin or a standard SaaS does not cover the specific rules of your business: complex pricing, approval flows, integrations with internal systems. ### How long does a custom software project take? It depends on complexity. A single module or integration can be ready in a few weeks. A platform with multiple integrations and complex business logic usually takes 3 to 6 months. ### Can you integrate the application with the ERP or CRM we already use? Yes. We work with the APIs your system already exposes, or we build a custom connector where none exists yet, [for example for SoftOne ERP](https://maxdev.ro/en/services/erp-integration/) or other internal systems. ### What happens if requirements change during the project? We work in stages, with intermediate deliveries you can test. That way we can adjust direction as we go, without rebuilding what already exists. ### Who owns the source code at the end of the project? The source code belongs entirely to you. You receive it in full when the project is finished, or along the way if we agree on that from the start. ### Do you offer maintenance and development after launch? Yes. The application grows with your business: you can add new modules or integrations without redoing what already works. ### What technologies do you use for custom software development? We choose the stack based on the project. [We frequently work with Next.js for applications and admin panels](https://maxdev.ro/en/services/web-app-development/), API integrations, and ERP systems such as SoftOne when there is a sync component with an internal system. --- ## Contact - Phone: +40 735 343 355 - Email: contact@maxdev.ro - WhatsApp: https://wa.me/40735343355 - Book a call: https://cal.com/daniel.maxdev - Address: 66A Theodor Pallady Blvd, District 3, Bucharest, Romania
