What Agencies Need That Other SMBs Don't
Five capabilities that separate agency-ready accounting software from generic SMB tools:
- Project profitability tracking. Tie billable hours + expenses + invoices to a specific client engagement to see margin per project. FreshBooks leads; QBO Plus and Xero Standard support it; Wave doesn't.
- Retainer + project hybrid billing. Retainers billed in advance consumed against time + deliverables, plus discrete project billing. FreshBooks handles this natively; others typically need add-ons.
- Utilization reporting. Billable hours / total hours per team member. Agency-essential KPI. FreshBooks Plus+ tracks natively; QB Time integration covers QBO; Wave is too basic.
- Multi-currency invoicing. International agency clients need to be invoiced in their currency. QBO Essentials+, Xero Growing+, FreshBooks Premium handle this cleanly.
- 1099 contractor payments at scale. Most agencies pay 10+ freelancers annually. IRS e-file mandate requires automated 1099-NEC generation. All major platforms support this.
FreshBooks — Best Overall for Agencies
FreshBooks is purpose-built for service businesses, and agency workflows are the canonical use case. Project profitability tracking ties time + expenses + invoices to client engagements; utilization reporting is native on Plus and Premium; retainers + project billing both supported; client portals streamline approvals; integration with Slack, Google Calendar, and Asana support modern agency operations.
Pricing: Lite ($17/mo, 5 clients — too few for most agencies), Plus ($30/mo, 50 clients — typical agency tier), Premium ($55/mo, unlimited clients — for established agencies). The client caps bite high-client agency models; Premium removes the cap. Read our FreshBooks review.
QuickBooks Online Plus — When You Need Inventory
Some "agencies" are actually product-and-service hybrids — design studios selling branded merchandise, marketing agencies running ecommerce side-businesses, creative shops with print-on-demand operations. QuickBooks Plus's inventory management beats FreshBooks here, and the ecosystem (750+ integrations) covers retail-adjacent workflows. Also relevant for agencies whose US accountant only knows QBO.
Trade-off: project profitability + utilization tracking aren't as polished as FreshBooks. QB Time add-on partially closes the gap. Read our QuickBooks review.
Xero — For Multi-User International Agencies
Xero wins for creative shops with 5+ users, international client roster, or strong UK/AU/NZ market presence. Unlimited users on every plan eliminates the per-seat math for collaborative teams. Multi-currency on Growing tier handles agency clients invoicing in USD/EUR/GBP/AUD. The 1,000+ app marketplace has stronger agency-specific PSA integrations (Workamajig, FunctionFox, BigTime).
For US-based agencies with US accountants, Xero is harder than QBO/FreshBooks — accountant network is smaller. Read our Xero review.
Zeni — For VC-Backed Tech Agencies
Agencies that are themselves venture-backed (rare but real — e.g. agencies serving startup clients, agency-as-a-product models, agencies operating embedded inside accelerators) benefit from Zeni\'s startup-specific dashboards (cash, burn, runway) + investor reporting. Less relevant for traditional bootstrapped agencies.
Wave — For Solo Agency Founders
Wave Starter is free forever and works for solo agency founders just starting out — invoicing, expense tracking, basic categorization. Limitations: no real project profitability, basic time tracking, weak utilization reporting. Use Wave for the first 6-12 months; graduate to FreshBooks Plus once you have 3+ clients or hire your first contractor. Read our Wave review.
When to Add a PSA Tool
Past ~$1M revenue, dedicated Professional Services Automation (PSA) software starts earning its keep. Productive, Workamajig, Mavenlink, Forecast, and BigTime all combine project management + resource scheduling + utilization tracking + invoicing — with accounting integration to QBO/Xero for the general ledger. Pricing typically $30-80/user/month.
The decision factor: when you spend more than 4-6 hours/month reconciling between project management software (Asana, Notion, Linear) and accounting software (FreshBooks, QBO), a PSA that does both pays for itself. Below that threshold, generic accounting + project management tools work.
Verdict
For most marketing and creative agencies in 2026: FreshBooks is the default unless you have inventory needs (QB Plus), international + multi-user needs (Xero), or solo-founder simplicity (Wave). The cost of getting agency accounting wrong shows up as invisible scope-creep losses; the cost of upgrading to better software is typically $200-600/year.
