Xero
Xero is the strongest challenger to QuickBooks and the favorite of many small business owners who find Intuit's pricing games tiresome. Its killer feature: unlimited users on every plan — a five-person team pays the same as a solo founder, while QuickBooks charges by seat. The interface is clean and friendly for non-accountants, and it handles invoicing, bank reconciliation, sales tax, 1099s, and reporting with ease, backed by a marketplace of 1,000+ app integrations. US plans run $25/month (Early), $55 (Growing), and $90 (Established). Just know the Early plan is tight — it caps you at 20 invoices and 5 bills per month, so most active businesses land on Growing. The main trade-off: payroll runs through a partner (Gusto, from $49/month) rather than being built in, and fewer US accountants know Xero than QuickBooks. Best for teams of 3–15 people who want predictable pricing without per-user fees.
