fixed quote, in writing
How much does a website, a web system or an app cost?
The honest answer is "it depends" — but it depends on things you can list. Here is what changes the price, what comes after delivery, and how to get a fixed figure before any work starts.
what drives the price
Five things move the price more than everything else.
- Screens and types of user. A five-page company site is a different conversation from a system where client, admin and finance each see different things.
- Integrations. Payments, ERP, invoicing, email, messaging: every connection to another system has its own rules — and some are badly documented.
- Custom design or a template. Designed screens cost more and deliver something that doesn't look like your competitor's site. When it needs a brand or art direction, the design is done with a partner studio, in the same quote.
- What you'll edit yourselves. An admin to change text, products or prices without depending on anyone is more work now and savings later.
- Existing data. Bringing customers, products or history from a spreadsheet or an old system can be simple — or half the project.
types of project
From simplest to most complex.
- Company website. A few pages, a contact form and an admin to edit it.
- Site with a catalogue or publishing. Many pages of the same kind, search and filters.
- Custom web system. Login, user roles, records and reports.
- System with integrations. Payments, ERP and third-party APIs.
- Android and iPhone app. Almost always with a web system behind it, plus store submission.
after launch
The cost doesn't end at delivery.
- Hosting and domain. Paid to the hosting company: a simple site costs little per month; a busy system, more.
- Maintenance. Security updates, fixes and small improvements — in a fixed monthly package or as needed.
- Third-party services. Payment providers charge per transaction; email, maps and AI usually charge per use.
and what about AI?
Has AI made it cheaper?
- Part of the work, yes. Repetitive code and tests come out faster — and on a fixed price, that gain becomes a shorter timeline for you.
- The expensive part is still human. Deciding what to build, designing, checking, and answering for what goes live.
- A site made by AI alone. Fine to get started. The trouble comes when it needs an integration, maintenance, or something the model didn't foresee.
before asking for a quote, answer
- Who will use it, and what do they need to get done in a minute?
- What do you do today without the system — a spreadsheet, a paper notebook, another system?
- What can wait for version two without killing the idea?
