Web app cost calculator
Describe your web application — a client portal, a B2B platform, a SaaS product or an internal tool — and the web app cost calculator splits it into modules: roles, screens, integrations, the admin. In about 15 seconds you see hours, a timeline and a price.
A website tells people about you; a web app does work for them. The calculator prices both — describe what users and staff do, not just the pages. The estimate is free; the contract fixes the price.

Price drivers
What moves the price of a web app
Screens are the visible part. The price sits in what is behind them: who may see what, which documents the system produces and what it talks to.
Roles
One role plus an admin is the cheap end; four or more roles with different access to the same data is the expensive one.
Documents
Plain uploads cost little. Generated contracts and invoices, versions and e-signatures are modules of their own.
Integrations
A payment provider and email are routine. Accounting, exports from legacy systems and partner APIs are where budgets grow.
Security
Standard sessions are part of every build. An audit log, a security pass and regulated data add work — and are worth it.
Reports
A CSV export is simple; live dashboards across several data sources need correct data at every step and fast queries.
The SaaS layer
One company is one thing. Many companies with their own workspaces, plans, billing and limits is a product in itself.
Orientation
Typical web app ranges in 2026
An orientation for planning, not a quote. One company often grows through several rows: a dashboard first, a client portal on the same backend next.
| Type | Typical content | Typical range | Timeline |
|---|---|---|---|
| Internal tool or dashboard | One team, one or two data sources, tables, filters, export | $8,000–$25,000 | 2–5 weeks |
| Client portal | Sign-in, orders and statuses, documents, invoices, notifications | $20,000–$60,000 | 4–10 weeks |
| B2B platform | Several roles, document flow, approvals, integrations, audit | $40,000–$120,000 | 2–5 months |
| SaaS product | Accounts for many companies, subscriptions or invoices, onboarding, settings, admin | $40,000–$150,000+ | 2–6 months |
The calculator prices your roles, documents and integrations module by module — and the team review tells you which part to build first. The article behind these ranges: Web Application Development Cost: Internal Tool to SaaS.
Modules
Modules the calculator prices
The parts a web app estimate is usually made of, each with its own hours.
Sign-in and roles
Accounts, strict sessions and permissions, so every role sees the same data from its own side.
Cabinets and screens
Orders, statuses, requests and settings — the screens each role works in every day.
Documents
Uploads, generated contracts, acts and invoices, versions and online signing, with owner checks on every file.
Integrations
Payments, email and SMS, accounting, maps and partner APIs, each with its error handling.
Dashboards and reports
Live data from your sources, filtered and charted for the decisions people actually make.
Admin panel
The back office where your team manages users, content and the rules of the system.
Three formats
Choose how we build it
The format decides who writes the code and how much engineering review goes into it — and with that, the price and the pace.
- AI / build
AI Build
Fastest path · prototypes & internal tools
AI generates the structure and most of the implementation. Engineers review integrations and the release. The lowest cost, for prototypes, internal tools and MVPs that test an idea.
- AI / engOur pick here
AI + DEV
Recommended for most MVPs
AI builds the scaffolding and the obvious parts. Engineers own the architecture, critical logic, integrations and full QA. Balanced pace and review, for customer-facing MVPs and B2B products.
- full / eng
DEV
Maximum quality & control
Senior developers own architecture and implementation end to end. AI is an internal tool for speed, never the final author. For production systems and regulated domains.
Client-facing web apps usually go AI + DEV: engineers own access rules, data and integrations, and AI takes the repetitive screens. Internal dashboards are a good fit for AI Build. Platforms that handle payments, personal data or regulated documents deserve DEV.
How it works
From a brief to an accepted product
The same five steps for every project, whatever we build. You always know what is agreed, what is paid and what is done.
Estimate
Describe the product in your own words, add a link or a file. In about 15 seconds you see the modules, the hours, the timeline and a price.
Team review
Our team reads the brief and the estimate, asks about anything unclear in your cabinet or on a call, and confirms the scope and the price. Nothing starts before that.
Contract
You sign a contract online: a fixed price, the scope split into modules, and a payment schedule — in full or by stages.
Milestones
We build module by module. QA checks each one before it reaches you, and the cabinet shows the work as it moves.
Acceptance
You have 7 days to review each module: accept it or send it back with a list of fixes. Your money stays in the project reserve until you accept.

Questions we get asked
How much does a web application cost?
As an orientation: an internal tool or dashboard $8,000–$25,000, a client portal $20,000–$60,000, a B2B platform $40,000–$120,000, and a SaaS product $40,000–$150,000+. The calculator prices your own roles, screens, integrations and admin.
Website or web application — which one am I pricing?
A website tells people about your company; a web application does work for them — takes orders, calculates, stores documents, shows each user their own data. Many businesses need both, and the calculator prices both: describe what visitors and staff do, not only the pages.
Does the technology change the price?
Less than people think. A mainstream stack — React and Next.js, Python or Node.js, PostgreSQL or MongoDB — keeps both the build and future hiring affordable. Exotic choices raise it, and proven services for sign-in, payments and email cost less than custom code.
What does a web app cost after launch?
Hosting and databases, third-party services such as email delivery, SMS, maps, e-signature or AI models, monitoring and backups, and support and changes as the business changes. Register the accounts in your company’s name.
Will I see the work before it’s finished?
Yes. Each module arrives in your cabinet for review, and you have 7 days to accept it or send it back with a list of fixes. The money stays in the project reserve until you accept.
