I meet owners who cannot change a phone number because “the developer has the access”. That is not a technical problem. That is a hostage situation with extra steps.
Three things that must be in your name
The domain (yourname.fr) at a registrar you can log into. The hosting or the export of the files. The Google Business Profile with you as owner, not a contractor who left in 2019.
If any of those bounce to someone else’s inbox, you are renting visibility. Ask for a screenshot of the owner list this week, not when you are angry.
How lock-in usually looks
A random subdomain on the agency brand. A builder you cannot export. “We keep the Google account for security.” Monthly fees that quietly include a threat: leave and the site goes dark.
None of that is required to run a shop website. It is required to keep you paying.
How I run it — and how you leave anyone
On bardin.me work, you keep the site, the Google account, the code and the deployment. The 25€/month is for hosting and updates, not for owning your name. You can walk.
If you are stuck elsewhere: request the domain transfer, request owner invite on Maps, download the site files. Do it while you still pay them. After the fight, they are slower.
