The employer is a user of Sage Businessvision software, which Sage claims to be supporting in exchange for a ~$1500 annual fee. Sage actually doesn't update the software or fix any bugs, they just send out the file needed for tax calculation (which is about 30 mins of work per year on their end). They have said they are discontinuing the software two or three times now, then retracted the statement. They are also pressuring all their on-prem customers to switch to cloud, but offering no porting options.

Very interesting, thank you.
