Ask HN: Quickbooks Alternative?

All businesses run on Quickbooks. And so the company keeps massively raising its prices each renewal cycle even though functionally nothing has changed. I am tired of this and looking to move to another provider. I am comfortable self hosting but my CPA and tax team will need access to all the files for my multiple businesses. Has anyone found an actual viable solution that doesn’t end in a complete dumpster fire for the accountants?
