What it costs and what decides the price
Prices depend on scope, so these answers explain what goes into a quote.
How much does a custom web app cost?
DEDEVS lists $1,000–$25,000 for scoped custom web apps, e-commerce platforms and portals, and from $30,000 for multi-tenant SaaS and larger platforms. Where your project lands depends on users and roles, workflows, integrations, data migration and what must be ready at launch. See the pricing page for the full breakdown.
What makes a project cost more?
More roles — each adds permissions, screens and tests.
Data migration — moving records from spreadsheets or an old system.
Complex integrations — older systems, two-way syncs, poor documentation.
Compliance — audit trails, HIPAA and similar rules.
High volume — many users or large data sets at once.
What does a quote include?
A written scope: the screens and workflows in the first release, the roles, the integrations, the acceptance tests we build against, what is excluded (usually hosting, third-party fees, support after launch and data migration unless listed), the price and the payment milestones. You approve it before work starts.
How are scope changes handled?
A change is written up with its effect on price and timeline, and nothing changes until you approve it.
Are there hidden fees?
No. Every charge is in the approved proposal or in a change you approved.
How do payments work?
Payments are split into milestones set out in the proposal. Each milestone gets an itemized invoice when it is delivered.
How a project runs
From the first call to launch.
How long does a custom web app take?
We give a timeline only after the first release is written down, because time depends on the same things as cost. The proposal splits the work into two-week sprints with a working build to review at each milestone.
How soon can you start?
Usually within one to two weeks of the proposal being signed, depending on current projects.
What happens on the first call?
We walk through what you need to build or replace, who uses it and which systems it touches. If it is a fit, we follow up with a written proposal.
How will I know how the project is going?
Sprint reviews with a working build, a shared project board, and direct contact with the engineers doing the work.
I've never worked with a software company before. How does this work?
You don't need any technical background to work with us. We start with a plain-language conversation about what you're trying to solve, explain your options without jargon, and walk you through every step — from the first call to launch and beyond.
What do you build?
Custom web applications, MVPs, SaaS platforms, customer and partner portals, mobile apps, AI integrations and workflow automation, plus QA and design for those products.
Code, data and life after launch
What you get and what happens once the app is live.
Who owns the code and data?
You retain full ownership of all data and intellectual property related to your project. The details, including when rights transfer, are written into your project agreement before work starts.
Do you sign NDAs?
Yes. We're happy to sign an NDA or confidentiality agreement before you share project details.
Can you migrate data from spreadsheets or an old system?
Yes, as a scoped item. We map the old fields to the new ones, run a trial import, check the results with you, then run the final import when you switch over.
Do you offer support after launch?
Yes. Each project includes a stabilization period after launch. For ongoing work we offer monthly retainers covering monitoring, fixes and new features.
Do you train our team?
Yes. Handover includes a walkthrough of the app for the people who will run it, plus documentation.
How is security handled?
Access is limited by role, inputs are validated on the server, and secrets stay out of the code. If your project needs a formal security audit or penetration test, it is scoped and quoted as a separate item.
