FAQ
Common questions
Everything you need to know about accounting for advertising & media buying agencies in London.
How do I manage cash flow when paying for media upfront?
We model your media float requirements monthly, forecast cash needs 3 months ahead, and help you negotiate better payment terms with media owners. Some agencies also use media financing facilities. We can advise on options.
How should I account for agency commission vs retainer fees?
Commission income (% of media spend) and retainer fees have different recognition timing and VAT treatment. We separate them in your accounts, ensuring correct tax treatment and clearer financial reporting.
What advertising costs are tax-deductible?
Creative development, talent fees, production costs, studio hire, stock footage, music licensing, ad tech subscriptions. All deductible. We ensure proper categorisation and maximize your claims.
Do I charge VAT on media buying services?
If you're buying media as an agent, VAT typically doesn't apply to the media spend itself. If you're reselling media, VAT applies. Cross-border campaigns add complexity. We review your setup and ensure compliance.
What should I look for in an accountant for a digital agency in London?
London digital agencies need an accountant who understands high operating costs, media spend passthrough, commission-based revenue, and the competitive salary landscape. Look for someone with direct experience of agency revenue models — not a generalist who will treat your media float as simple expenditure. Alto works exclusively with digital and creative agencies, so we understand your model from day one.
How can London agencies reduce their tax burden with high overheads?London
London's high costs can actually work in your favour for tax purposes. We ensure all qualifying expenses: office rent, travel between client sites, equipment, and R&D on digital tools are properly claimed, and we structure director remuneration to minimise the combined tax burden.
Should London agencies consider relocating to reduce costs?London
Not necessarily. We help London agencies model the true cost-benefit of relocation vs. hybrid working, factoring in client proximity, talent access, and lease obligations. Often a hybrid model with a smaller London base delivers the best financial outcome.
