The owner asks you before signing up for any system. Start getting paid for that answer.

Partner Accounting Program: the firm refers CertuAI or resells it under its own brand and price. CertuAI bills the client, issues the invoice, handles setup and provides support; the firm gets paid every month for as long as the client pays. You earn 30% to 40% of everything the client pays, every month, for as long as they remain a client. The rate rises with volume: 30% up to 4 paying clients in the month, 35% from 5, 40% from 15. Moving up a tier raises the commission on all of that month's clients, not just the next one. It is not a tax ERP: it doesn't issue invoices or file SPED, and it complements the firm's system.
