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.
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.
Frequently asked questions
What is the best accounting software for creative and marketing agencies in 2026?
FreshBooks for most agencies — its project profitability tracking, time tracking, and invoicing UX are purpose-built for agency workflows (billable hours, retainer + project blend, client portal). QuickBooks Online Plus is the alternative when agencies need inventory tracking (product agencies, ecommerce-adjacent operations) or work with US accountants who only know QB. Xero wins for multi-user creative shops with international clients.
Why is project profitability tracking critical for agencies?
Agencies routinely discover that their highest-revenue client is also their lowest-margin one because scope creep ate the profit. Project profitability tracking ties billable hours, expenses, and invoices to a specific client engagement so margin per project becomes visible. FreshBooks is class-leading here; QuickBooks Plus and Advanced support it but with less polish; Xero supports project tracking on Standard+ tiers; Wave does not.
How do agencies handle retainer vs project-based billing?
Modern agency accounting needs both. Retainers are billed in advance and consumed against time + deliverables; projects bill on completion or milestone. FreshBooks handles this natively — set up a retainer with deposit, log time against it, track unused balance. QuickBooks Online + a project-tracking add-on (e.g. Productive, Workamajig) works for larger agencies. Avoid trying to manage retainers manually in spreadsheets — it scales poorly past 5 clients.
Should agencies use specialized PSA software instead of generic accounting?
For agencies past ~$1M revenue, possibly yes. Professional Services Automation (PSA) tools like Productive, Workamajig, Mavenlink, and Forecast combine project management + resource scheduling + time tracking + project profitability + invoicing in one platform, with accounting integration to QuickBooks/Xero for the actual general ledger. Below $1M revenue, FreshBooks alone typically covers agency workflow at meaningfully lower cost.
How do agencies track utilization rates and billable hours in accounting software?
Utilization rate = billable hours / total hours worked. Most agencies target 65-80% utilization for senior staff and 80%+ for juniors. FreshBooks Plus and Premium support utilization reporting natively. QuickBooks Time (formerly TSheets) integrates with QBO for utilization tracking. Toggl + Harvest + Hubstaff all integrate with QB/Xero. Wave's time tracking is too basic for serious agency utilization analysis.
What about agencies that bill in multiple currencies?
Multi-currency matters when serving international clients. QuickBooks Online Essentials+ supports multi-currency with rate auto-update. Xero supports multi-currency on Growing+. FreshBooks supports multi-currency on Premium tier. Wave has basic multi-currency. For agencies with EU/UK clients invoicing in EUR/GBP, Xero or QBO Plus are the cleaner choices.
How do agencies handle 1099 contractor payments?
Most agencies use a mix of W-2 employees + 1099 contractors (freelance designers, developers, writers). All major accounting platforms (QB, Xero, FreshBooks, Wave) handle 1099-NEC generation. For agencies paying 10+ contractors annually, the IRS e-file mandate (T.D. 9972, effective tax year 2023+) requires e-filing — all platforms support this. Bill.com integration adds AP automation for high-volume contractor payments.
