Zoho Books comes first because it keeps proper double-entry books free while revenue stays under $50K a year, then charges $15 a month for up to 3 users. Odoo is second for teams of any size: its Accounting app alone is free for unlimited users, but adding a second app makes everyone pay. Zoho Invoice is third and has the higher grade, but it only sends invoices and keeps no books. Xero narrowly missed: every plan includes unlimited users, but there is no free plan and Early stops at 20 invoices. QuickBooks Online does the whole job but costs $38 a month for one user.

   Teams of any size that want to pay nothing 向け

AI bill scanning uses credits bought separately, and implementation services are not included.
