Spreadsheets, disconnected tools and generic software stop working when teams need roles, approvals and shared data. DEDEVS builds the application around the workflow: accounts, permissions, dashboards, integrations and deployment.
Problems a custom web app solves
Work lives in spreadsheets and inboxes
Requests, approvals and status updates are spread across email threads and shared files, so nobody can see who changed what or what is still waiting.
Off-the-shelf software fits badly
The tool you pay for covers most of the job, and your team works around the rest by hand. A custom app is built for the steps your business actually runs.
Different people need different views
Staff, managers, customers and partners each need to see and do different things. Accounts and role-based permissions keep each view correct.
Your systems do not talk to each other
Data is re-typed between your CRM, payments, accounting or an external API. Integrations move it automatically, within limits agreed in the scope.
Three kinds of web app we build
A first product
A founder's first release: sign-up, the one workflow users pay for, and an admin view. Scoped as an MVP so it can launch before it tries to do everything.
Internal operations
A system for your own team that replaces a spreadsheet workflow: intake, assignment, approvals, reporting and exports.
A customer or partner portal
One place where customers or partners submit requests, track orders and see status, while your team works the same records from the inside.
The first-release checklist
Every project starts by writing these down. They become the scope, the price and the tests the finished app has to pass.
Users and roles
Who logs in, and what each role is allowed to see, create, approve or change.
Screens and workflow
The steps a record moves through, from first entry to done, and the screens each step needs.
Data
What is stored, where it comes from today, and whether existing records must be migrated in.
Integrations
Which outside systems the app must read from or write to at launch, and which can wait.
Acceptance tests
The agreed checks that decide when a feature is finished, written before development starts.
What changes the price and the timeline
Scoped web apps are listed from $1,000 to $25,000. Where a project lands depends on these factors, and we confirm the price and timeline in writing before work begins.
Number of roles
Each extra role adds permission rules, screens and test cases.
Integrations
A well-documented API is quick to connect. Older systems, custom file formats and two-way syncs take longer.
Data migration
Moving records from spreadsheets or an old system needs mapping, cleaning and a trial import.
What must exist at launch
The more features that must be ready on day one, the larger the first release. Moving features to a second release is the fastest way to reduce cost.
From first call to handover
01 Scope call
We walk through your workflow, users and systems, and write down the first release and what is left out of it.
02 Written proposal
Scope, price, milestones, exclusions and acceptance tests, in one document you approve before development starts.
03 Build and test
Two-week sprints with a working build to review at each milestone, tested against the agreed acceptance criteria.
04 Launch and handover
Deployment, admin access, documentation and a walkthrough for your team.

What you get that you would not elsewhere
You talk to the people building it
Scope, questions and reviews go directly to the senior engineers writing the code.
Scope before price
The first release, its exclusions and its acceptance tests are written down and approved before a final price is given.
Full-stack delivery
Database schema, API, interface and cloud deployment are handled by one team.
Visible progress
Working builds at each milestone and a shared project board, so you can see what is finished.
