Question 1

Is there a Joist alternative that does not lock my old invoices behind a subscription?

Yes. Slap Invoice saves every invoice and estimate as a PDF on your iPhone and iCloud Drive. Your records stay accessible even after you stop paying, unlike Joist where access to past invoices can require an active subscription.

Slap Invoice is a one-time $49.99 purchase for unlimited invoices and estimates. Joist charges monthly and adds higher Elite tiers.
