Salesforce is running an ad claiming 40% off to beat Zoho. We have watched this playbook for years where they give deep discounts to get you in, followed by aggressive escalation once you're locked-in.
Before you switch anything, ask them to show you standardised multi-year pricing. If they don't, that's your answer. Enterprise software is a con-game of "discount" bullshit by vendors like Salesforce. Buyer beware!
As for "old CRM", Salesforce is a garbage bin of acquired enterprise software companies over decades, held together with bubble gum and duct tape.
