Three eras, three ways to pay. Drag to see where we stand today.
A decent website meant several thousand euros and months of waiting. Every change went back through a quote. Reserved for companies that could tie up that budget.
Several thousand euros, and months
Online tools billed every month, built on templates everyone recognises. You pay forever for a site you don't really own, and can only shape within the limits of the tool.
A lifelong subscription, a shared template
A client area, accounts with logins, an app to manage your teams, payments wired to your own data: that is where those tools stop. You are back to custom development, and back to the original budget.
Impossible, or back to square one
A developer's bespoke work, without a developer's budget. Website, client area, logins, payments, a business app to run your teams: all built for you, and yours to keep. You pick the all-inclusive subscription or the fixed price, agreed before we start.
