I manage multiple stores, can Adjusto handle that?

Both customer database and user accounts can be shared across multiple stores (ship to address) within the same organisation, (GDPR compliant). Only specific users can access sales information from another store.

Are updates to the App paying?

No, our pricing model is a yearly subscription that includes all new features included in your plan.

New features and fixes are published in the change log

Will it cost me more if  I have many users?

No. Our pricing is per store only (ship to address).

Does Adjusto run on Mac & Windows?

Currently Adjusto is only available on the mac, but please get in touch with us if you would be interested in a Windows version.

Does Adjusto run in the browser?

No, Adjusto is a native, lightweight and high-performance macOS application that communicates with with a secured database sever in a cloud managed by us. Your database sever is dedicated, which means your data is physically separated from other Adjusto customers.

Can I import my customers data from my old system?

If you're a GestioTech user, yes, at no charge.
If you're using another system, let's see what you've got. Contact us.

How long will GestioTech be supported?

GestioTech and GestioTech mini will be supported until December 31st 2020. After that, GestioTech mini APIs will cease to work. GestioTech mini will still launch but will not be able to communicate with GestioTech anymore.
GestioTech will keep working if your license is valid but will not be supported anymore.


About Us

From GestioTech to Adjusto

1-more-thing is a Belgian and French company based in Brussels and Paris, specialized in digital transformation and bespoke software development, as well as Business Intelligence.
In 2018 we hired an amazing developer, Yann Trauchessec, who had a great product, GestioTech, already deployed at a number of Apple Authorized Service Providers (AASP) across France, Switzerland and Belgium.
It was good, but not perfect, so we decided to rewrite it from scratch so it's much faster, much easier to use and update, and works seamlessly with new GSX APIs.
You'll never believe how much time Adjusto can buy you.


Thank you!
