Compare the scope before comparing the price
When you compare a London agency with a remote development team, start with what each proposal includes. An app with a few screens and one user role is a different project from a marketplace with payments, live updates and an operations dashboard.
65Seven Labs is a remote team working through a UK registered company. The figures below come from our own MVP calculator. They are planning estimates for our delivery model, not a survey of London agency prices or a quote for a named client.
Where our estimates start
The calculator starts with a base build based on screen count:
| Screen count | Base build before additional features |
|---|---|
| Up to 8 | €6,000 |
| 9 to 12 | €13,000 |
| 13 to 20 | €20,000 |
| More than 20 | €30,000 |
Web, iOS and Android each use the base platform multiplier. A shared iOS and Android build adds 15% to the base and feature work in this model. A design sprint is added separately because the same design work supports both platforms.
The screen count is a starting point. Accounts, payments, maps, search, integrations and staff tools change the total. Read the calculator methodology for the full calculation.
A worked mobile MVP example
Consider a product with nine to twelve screens, iOS and Android support, user accounts, payments and an admin dashboard. Assume a design sprint, a standard schedule and no regulated-sector multiplier.
| Item | Amount |
|---|---|
| Base build | €13,000 |
| Accounts | €750 |
| Payments | €1,500 |
| Admin dashboard | €2,500 |
| Build subtotal | €17,750 |
| Build subtotal after the 1.15 platform multiplier | €20,412.50 |
| Design sprint | €2,500 |
| Total after rounding to €250 | €23,000 |
The calculator shows a planning range of €18,500 to €27,500 around that point estimate. This is an illustrative scope, not a past client's invoice. The scope and price are fixed in writing after the two week-one scoping sessions.
For the same example on web alone, the point estimate is €20,250, with a range of €16,250 to €24,250. You can start a web estimate or start the mobile example and adjust the inputs.
The work that screen counts can hide
In Good Way, the product includes location tracking, different ride options and a driver payment workflow. Those requirements affect backend behaviour and integration testing as well as the screens.
Dash includes a customer loyalty experience and business tools. If your product needs staff to manage customers, rewards or reports, include that dashboard in the brief from the start. Calling it an “admin panel” does not make its workflows automatic.
The same principle applies to web products: permissions, data imports and third-party systems can create more work than the visible page count suggests.
Questions to put beside every agency estimate
- Which user journeys and screen states are included?
- Does the price cover backend APIs, data storage and staff tools?
- Who supplies the design, copy, data and external-service accounts?
- Which devices and browsers will be tested?
- What happens if an integration does not support the proposed flow?
- Who owns the repositories, credentials and deployment setup?
- How are scope changes, hosting, third-party usage and ongoing support priced?
Ask for exclusions as well as inclusions. Compare the total cost of reaching and operating the same release, including the time your own team must spend managing it.
Turn a planning number into an agreed scope
Use the MVP calculator for an initial range. We then work through the screens, roles, integrations and launch requirements before fixing the price and delivery date. If you are comparing whole teams rather than one product, the savings calculator shows an immediate EUR estimate at €25–€40 per total project hour, alongside sourced agency rate benchmarks.
