Web agency accounting has layers of complexity that standard small business tools handle imperfectly. Revenue arrives from multiple models at once: fixed-price project fees, monthly retainers, time-and-materials billing, and pass-through hosting costs billed at a markup. Labour costs span full-time employees, part-time staff, and a rotating roster of freelance contractors with 1099 reporting obligations.
Client P&L needs to be visible at the individual engagement level — not just rolled up into total revenue. A retainer that looks profitable at the top line may be losing money on hours actually worked.
The five tools in this guide cover the range from accessible mid-market accounting platforms to enterprise-grade project accounting systems, matched to typical web agency growth stages.
What Web Agencies Need from Accounting Software
Web agency accounting centres on five operational needs that generic small business tools do not fully address.
- Project-based billing — invoicing clients for fixed-price projects, milestones, time-and-materials, and retainers from the same accounting system, with revenue allocated per project
- Retainer revenue tracking — recurring monthly retainer revenue needs to be tracked as deferred revenue until the month’s work is performed, ensuring accurate month-to-month P&L
- Per-client and per-project P&L — understanding whether each client engagement is profitable requires allocating all associated costs (team hours, contractor fees, software, hosting) against that client’s revenue
- Contractor and subcontractor payment tracking — agencies routinely use freelance developers, designers, and copywriters; every payment must be tracked for 1099 reporting and COGS allocation
- Markup on pass-through costs — hosting, domain registration, plugin licences, stock photography, and third-party services billed to clients at a margin need to appear correctly as revenue and COGS
- Multi-client financial reporting — agency principals and financial directors need to see total revenue, gross margin, and net profit broken out by client or project, not just consolidated

QuickBooks Online
QuickBooks Online is the most common accounting platform in US web agencies. Its broad ecosystem compatibility — bookkeepers, accountants, and tax preparers in the US are trained in QuickBooks by default — makes bringing in financial support straightforward. For agency-specific accounting, the critical plan is Plus ($65/month) or Advanced ($235/month).
Plus adds project profitability tracking, inventory management, and up to five users. The 1099 contractor workflow is native: mark a vendor as a 1099 contractor, track all payments through the year, and generate 1099-NEC forms at year-end. Time tracking for billing is available through QuickBooks Time as an integrated add-on. For agencies managing 5 to 30 active clients with mixed billing models, QuickBooks Online Plus is the most practical all-around choice.
Xero
Xero is a strong alternative to QuickBooks for agencies that need unlimited user access, prefer Xero’s bank reconciliation interface, or bill clients internationally. All Xero plans include unlimited users at a fixed price. The Projects module adds time tracking, expense allocation, and per-project profitability reporting — directly relevant for agencies tracking margin per engagement.
Multi-currency handling is stronger than QuickBooks at comparable price points, which matters for agencies billing in EUR, GBP, AUD, or CAD. Xero does not generate 1099 forms natively, a material gap for US agencies with multiple contractors. Gusto and third-party 1099 tools fill the gap but add cost. Plans start at $20/month.
FreshBooks
FreshBooks is the most accessible entry point for small web agencies — typically three to eight team members, a handful of active clients, and a billing model centred on retainers and project work. Its time tracking is native and among the best in the category: team members log hours against clients or projects, and those hours convert directly to invoice line items with one click. Recurring invoice automation handles retainer billing without manual monthly sends.
The limitations appear at scale: FreshBooks is less comprehensive than QuickBooks or Xero on accounting depth, 1099 tracking requires manual record-keeping outside the platform, and multi-entity consolidation is not supported. For agencies up to $2M in revenue that prioritise ease of use and client billing, FreshBooks is the most accessible option. Plans start at $19/month.
Sage Intacct
Sage Intacct is a cloud ERP designed for mid-market businesses with advanced project accounting needs. For agencies above roughly $5M in revenue or with 20+ concurrent projects, it delivers capabilities the other platforms do not. These include revenue recognition automation (ASC 606), WIP accounting, multi-dimensional reporting (by client, department, project, and geography), and multi-entity consolidation for agency groups with multiple brands.
AICPA has recognised Sage Intacct as the preferred financial management platform for professional services firms. Implementation requires more setup time and a larger budget — pricing is custom and typically starts at several hundred dollars per month. Sage Intacct is not appropriate for agencies under $3M in revenue; it is the right long-term platform for agencies scaling beyond what QuickBooks Advanced or Xero can handle.
Zoho Books
Zoho Books is the strongest value option for cost-sensitive agencies or those already using Zoho CRM, Projects, or Desk. It covers the core agency workflow: project billing, time tracking, expense categorisation, bank feeds, recurring invoices, multi-currency, and financial reporting. A free plan is available for businesses with revenue under $50 000.
Integration with Zoho CRM connects client billing data to your sales pipeline; Zoho Projects links time entries to invoices. The platform is weaker on per-project profitability analytics compared to QuickBooks Plus or Xero Projects, and 1099 generation requires an add-on or third-party tool. For agencies seeking QuickBooks-level functionality at lower cost, Zoho Books is the most practical value option. Plans start at $20/month.
How to Choose
Step 1: Determine your team size and multi-user requirements.
If multiple owners, a project manager, a bookkeeper, and an external accountant all need simultaneous access, Xero’s unlimited-user pricing ($47/month flat) is often cheaper than QuickBooks. QuickBooks charges per seat on all plans beyond the base tier.
Step 2: Prioritise project profitability tracking if it is currently a blind spot.
Agencies that do not know their gross margin per client operate with a significant financial blind spot. QuickBooks Online Plus, Xero Projects, FreshBooks, and Sage Intacct all provide per-project P&L. Test each platform’s project reporting against your actual data before committing.
Step 3: Confirm your 1099 contractor workflow.
US agencies with multiple contractors need a clear 1099-NEC path. QuickBooks Online is the cleanest native solution. If you choose Xero or FreshBooks, plan for a third-party 1099 filing service (Track1099, Tax1099, or similar) at year-end.
Step 4: Match platform to revenue stage.
Under $500K revenue: FreshBooks or Zoho Books. $500K to $5M: QuickBooks Online Plus or Xero with Projects. Over $5M with complex multi-project accounting: Sage Intacct. Match the platform to your current complexity, not your aspirational size.
