Map: https://g.co/kgs/6Lt2hQB business systems built around how you actually work. we design and build custom software for internal tools, client portals, and operations systems, when spreadsheets and off-the-shelf tools stop fitting the job. ## Overview not every problem is a website or a mobile app. many teams need software that encodes their process: approvals, inventory rules, partner portals, scheduling boards, or admin tools that only make sense for their business. fossasoft builds those systems from real workflows: clear screens for the people who use them every day, and structure that can grow without turning into a fragile pile of scripts. this is practical software that replaces chaos with a system your team owns. ## What we do - **internal tools and admin systems:** dashboards, back-office apps, and staff tools that replace spreadsheet-driven operations. - **client and partner portals:** logged-in experiences for customers, vendors, or franchisees to request, track, and manage work. - **workflow and rules engines:** approvals, statuses, assignments, and business rules that match how decisions really happen. - **data models that fit the business:** entities, permissions, and history designed for your domain, not forced into a generic saas shape. - **integrations with existing stacks:** connect accounting, crm, ecommerce, or hardware so the custom system is the hub, not another silo. ## How we work - we map the real process with the people who run it before we draw screens. - we ship usable slices early so operators can steer the product. - we prefer clarity over cleverness: tools staff can learn in a day matter more than novelty. - handoff includes who owns data, access, and the next improvements. ## Typical projects - operations portals for multi-location businesses - custom admin systems replacing shared spreadsheets - partner extranets and dealer portals - internal request and approval platforms - domain-specific tools that commercial saas cannot cover ## Deliverables - working custom application for web (and mobile where needed) - roles, permissions, and core workflows - integrations as agreed - admin documentation and training - a path for ongoing changes after launch ## Outcome software that matches your process instead of forcing your process to match a generic product. teams spend less time fighting tools and more time doing the work the system was built to support. ## Contact - https://fossasoft.com/contact/ - info@fossasoft.com - +30 2352 031 337 - https://fossasoft.com/company/
