Client notes
In their words.
I never expected such a major fix to our order-intake software to be this fast — or this well priced.
We got hacked and had no backups. Jiss Tech rebuilt everything from scratch and had us back up and running in under a week — with stronger security than before.
Identifying and fixing the issues in our software was smooth, and the communication was great throughout.
Things were a mess at my firm — exposed client data, broken software. Jiss Tech came in and lifted everything.
