The Challenges Performance Marketing Agencies Face in Cardiff
These accounting challenges are especially relevant for agencies in Cardiff:
Ad Spend vs Revenue Confusion
15-20% of PPC agencies can't clearly answer "What's our actual profit?" Managing £50k-£500k monthly ad spend while tracking true agency margins. Most accountants miss the complexity of media passthrough accounting.
Surprise Tax Bills & VAT Traps
Variable client onboarding = unpredictable revenue. Without quarterly tax planning, you face £5k-£15k surprise bills or miss VAT thresholds. Pro-active forecasting prevents both.
Hidden Unprofitability
You see client margins but not your own. The average PPC agency loses 15-20% of clients annually without knowing. Monthly client profitability analysis reveals which clients drain cash.
Slow-paying Welsh Government contracts
Public sector work from Welsh Government and local councils can take 60-90 days to pay. Cardiff agencies relying on government contracts need robust cash flow management to bridge payment gaps.
Navigating Welsh and UK funding streams
Cardiff agencies can access both Welsh Government grants and UK-wide schemes, but the eligibility criteria differ. Missing available funding because your accountant only knows one system costs agencies thousands annually.

Ad Spend Accounting & Reconciliation
Stop guessing. We separate media passthrough from revenue, reconcile platform APIs (Google, Meta, TikTok), and show your true agency margin monthly. Clarity on what's profit vs. what's client spend.
Quarterly Tax Planning & Forecasting
Monthly profit forecasts + quarterly tax planning = no surprises. We flag VAT thresholds, Corporation Tax liabilities, and payroll planning 3 months ahead. Cash planning becomes predictable.
Client Profitability Analysis
Monthly P&L per client shows which are profitable vs. loss-makers. Adjust pricing, drop clients, or negotiate better terms before margins erode. Data-driven decisions, not guesswork.
