Web Application Development in Berlin
Your Berlin business runs on workarounds. Customer data lives in spreadsheets. Orders are tracked in email threads. Your team copies information between five different apps because none of them do exactly what you need. GridArray builds the custom web applications that replace all of it, shaped around how your business actually works.
Berlin's business landscape spans from early-stage startups to established Mittelstand companies going digital. Both ends share a common frustration: the tools available on the market were built for someone else's workflow. Custom web applications close that gap, giving Berlin businesses exactly the operational backbone they need without paying for features they will never use.
Off-the-shelf tools that never quite fit
Berlin's SMEs and scaleups are caught between SaaS tools that cover 80% of the workflow and the remaining 20% that requires manual duct-taping. The monthly subscription fees add up, the integrations are fragile, and your team spends more time working around the tool than working in it.
Critical business logic trapped in spreadsheets that break when someone edits the wrong cell
SaaS subscriptions costing thousands per month for features you barely use
Manual data entry between systems that should talk to each other
Customer-facing processes that feel clunky because the tool was not built for your workflow
Web apps built for exactly how your team works
We design and build custom web applications that fit your workflow, not the other way around. Every project starts with understanding the real process, the edge cases your team handles daily, and the bottlenecks that slow everything down. You get software that eliminates manual work and scales with your business.
Customer portals that reduce support tickets by letting clients self-serve
Internal dashboards that unify data from CRM, payments, and logistics
Scheduling and booking systems your team will actually use
Inventory management without the spreadsheet chaos
