Payroll, AP/AR & Bill Pay with AI

Payroll, bill pay, receivables, expense and spend platforms with accountant partner programs and named AI features.

Eighteen tools, nearly all of them with an accountant program, because payroll and bill pay are the services firms run for clients rather than for themselves. Payroll: Gusto (Simple $49 a month plus $6 a person), QuickBooks Workforce Payroll ($50 plus $7 an employee, with Payroll AI on Premium), SurePayroll's white-label resale, Rippling from $8 an employee, Deel for international teams from $49 a contractor, and the quoted enterprise names, RUN Powered by ADP and Paychex Flex, each with an AI assistant for payroll and HR questions. Bill pay and AR: BILL, Melio (free for the firm), Forwardly ($0 platform, pay per transfer), Chaser for collections and Relay's banking with bill pay.

Expense management is the third strand — Expensify, Ramp, Brex, BILL Spend & Expense, Zoho Expense and Sage Expense Management — and most of it is free or close to it at the client level (BILL Spend & Expense and Brex Essentials at $0 per user, Zoho Expense from $3, Expensify Collect at $5), with the AI doing receipt matching, GL coding and fraud flags. Every listing names the ledgers it syncs to and what the partner program gives the firm: revenue share, wholesale pricing, a free subscription for the practice, or a directory listing.

Featured spot open. Put your tool at the top of this category for $149/month.
