QB 2021 was the last version without a subscription, so I've kept that. If I need a new copy (like a new computer) I use a company OCITHUB who sells lots of desktop versions at discounted prices.

Since QBO is so expensive I've transitioned most clients to QBO Ledger. At $10 per month (plus in MD it's now 3% sales tax...) it does everything regular QBO does but (a) a lot cheaper, (b) no A/R, A/P, or inventory. So for most of my write-ups no client has complaned about $120/yr I bill them. For payroll I use ADP and it automatically imports into Ledger.
