Best invoicing apps
The Best Invoicing Apps for Agencies in 2026
An agency needs invoicing that survives multiple clients, projects and team members, not just a single freelancer sending the odd bill. The tools below are ranked on invoicing strength, project and time tracking, how many people can work in them, and price. Auritrack sits fourth on purpose: it is an AI bookkeeping app, not a dedicated billing suite, so we rank it honestly against apps built for the job.
FreshBooks
From ~$21/moFreshBooks is invoicing-first with the extras agencies actually use: estimates, a client portal, and time and project tracking to turn billable hours into invoices. Plans start around $21/month with extra team members about $11/month each, so a growing team adds up, but the client-billing workflow is the most complete here.
QuickBooks
From $35/moQuickBooks pairs strong invoicing with full double-entry accounting, payroll and tax integration, which matters once an agency has staff and real books to keep. It starts around $35/month with no free tier and can feel heavy if all you want is to bill clients.
Xero
From $25/moXero is the pick for a bigger team because every plan includes unlimited users, alongside full accounting and automatic bank feeds. It starts at $25/month, but multi-currency is locked to the top Established plan and the cheapest tier caps invoices and bills, which agencies with many clients hit quickly.
Auritrack
Free tier + AI from $3/moAuritrack ranks fourth here honestly: its invoicing is partial, aimed at small-business records and reports rather than a full client-billing and project workflow like FreshBooks or Xero. It earns its place on the other side of agency admin, using AI to log expenses by chat or statement import in any currency, on a free tier with AI features from $3/month.
The verdict
For most agencies, FreshBooks is the top pick because invoicing, estimates, client portals and time tracking are its whole reason to exist. Choose Xero if you want unlimited team seats with full accounting, QuickBooks if payroll and tax integration matter, or pair a dedicated billing app with Auritrack to let AI handle the expense side of the books.
