We’re Sidekick.
A specialist accounting and CFO advisory firm built entirely for agencies and B2B service businesses. Six years in. Over 100 agencies helped. All focused on one thing: making finance work.
Why we built this.
Most accounting firms are built for businesses in general. We're built for one type: agencies that are growing, that want to grow further, and that keep running into the same financial ceiling.
The ceiling looks different for everyone. For some it's margins that don't reflect the revenue. For others it's decisions made on gut feel because the numbers aren't there. For some it's just wanting an accountant who actually calls, not one you chase at year-end.
Sidekick exists to fix that. We combine clean, compliant accounting with the kind of commercial thinking that moves the needle: pricing, margins, cash, hiring decisions, exit strategy. Delivered by people who've spent years working exclusively with the kind of businesses you're building.
How we work.
We deliberately keep our client list small so we can go deep with each one. This isn’t a high-volume firm.
We only take on clients we can genuinely help.
Every enquiry is reviewed personally. If we don't think we can move the needle for you, we'll say so, and point you somewhere better.
Agencies only. No generalist advice.
Six years working exclusively with agencies means we understand your cost structure, your pricing dynamics, your margin pressure points. We don't explain agency business models to our clients.
We contact you. You don't chase us.
We spot things before they become problems. Tax planning before year-end. Cash flow warnings before they bite. Decisions supported before they're made.
We care about your business, not just your books.
Compliance is the floor. The real work is helping you understand your numbers well enough to make the decisions that build a better, more profitable business.
Regulated. Qualified. Accountable.
Sidekick Accounting Ltd is a registered firm with the Institute of Chartered Accountants in England and Wales. Rayhaan is a fully qualified Chartered Accountant. That means professional standards, regulated advice, and full accountability for everything we do.
