Specialist Agency Accountant vs General Accountant

Your accountant should understand retainers, media passthrough, and project-based revenue without you having to explain it every quarter. Here’s how a specialist agency accountant differs from a general practice.

Understanding Agency Revenue Models

Agencies don’t operate like most businesses. Revenue comes in multiple forms — monthly retainers, one-off project fees, and media passthrough (where you collect ad spend from clients and pass it through to platforms like Google or Meta). Each has different implications for cash flow, VAT treatment, and profit recognition.

A general accountant may treat all incoming funds as revenue, inflating your turnover and potentially your tax liability. A specialist agency accountant understands the distinction between revenue you’ve earned and money you’re holding temporarily on behalf of clients.

Tax Planning for Agency Directors

Most agency owners are also directors of their limited company. The way you extract profits — salary, dividends, pension contributions, or a combination — has a significant impact on how much tax you pay.

A general accountant will typically advise on the standard salary-plus-dividends approach. A specialist goes further: they understand the seasonal nature of agency cash flow, can advise on timing dividend declarations around project completions, and help structure director remuneration to reflect the reality of running a services business.

  • Optimal salary and dividend split based on current tax bands and NI thresholds
  • Pension contribution planning to reduce Corporation Tax liability
  • Timing of dividend declarations to manage personal tax across tax years
  • R&D tax credit claims for agencies developing proprietary tools, processes, or technology
  • Capital allowances on equipment, software, and office fit-outs

Industry-Specific Knowledge

Agency accounting involves nuances that general practices rarely encounter. Contractor and freelancer management (including IR35 considerations), scope creep affecting project margins, the impact of client payment terms on cash flow, and the challenge of scaling a team when revenue is project-based rather than guaranteed.

A specialist agency accountant has seen these patterns before. They can advise on structuring contractor agreements to manage IR35 risk, help you understand your true cost per head (including bench time), and flag when your debtor days are creeping up before it becomes a cash flow problem.

  • IR35 compliance for contractors and freelancers your agency engages
  • Understanding utilisation rates and their impact on profitability
  • Client payment terms and debtor management strategies
  • Scaling decisions: when to hire permanently vs use contractors
  • Navigating scope creep and its effect on project margins

Proactive Advice vs Reactive Compliance

The traditional accountant relationship is reactive: you send your records, they file your returns, you hear from them once a year. For an agency navigating growth, hiring decisions, and fluctuating cash flow, that’s not enough.

A proactive agency accountant provides regular management information, flags issues before they become problems, and helps you make informed decisions about hiring, pricing, and investment. They’re a finance partner, not just a compliance function.

Feature
Reactive (General)
Proactive (Specialist)
Reporting frequency
Annual accounts only
Monthly or quarterly management reports
Cash flow
Discussed when there’s already a problem
Forecasted and monitored continuously
Tax planning
Calculated at year end
Planned throughout the year with quarterly reviews
Business decisions
Not typically involved
Supports hiring, pricing, and investment decisions with data
Communication
Responds when contacted
Regular check-ins and proactive alerts

Technology and Xero Expertise

Cloud accounting software like Xero has transformed how agencies manage their finances. But the software is only as good as the setup behind it. Chart of accounts, tracking categories, bank rules, and integrations all need to be configured for how an agency actually operates.

A general accountant may use Xero but configure it generically. A specialist sets it up to give you the reporting you actually need: revenue by client, profitability by project, and a clear picture of your cash position at any time. They’ll also integrate it with your project management and invoicing tools where possible.

  • Xero setup tailored to agency workflows with proper tracking categories
  • Integration with project management tools and time-tracking software
  • Automated bank feeds and reconciliation rules configured for agency transactions
  • Custom reporting dashboards for revenue by client, project profitability, and team cost
  • Receipt capture and expense management through Xero’s ecosystem
