Client stories
What our clients say
"Pinnacle transformed how we understand our finances. For the first time, we actually know where our cash is going — and where it should go next."
"James and the team saved us over £28,000 in our first year through an R&D claim we didn't even know we were eligible for. Worth every penny."
"After years of muddling through with a part-time bookkeeper, switching to Pinnacle was like turning the lights on. Fast, clear, and always reachable."
Common questions
Everything you need to know
Fees vary by scope. At Pinnacle, annual accounts and corporation tax for a small limited company start from £800/year. Management accounts and bookkeeping are priced monthly from £150–£450/month depending on transaction volume. We provide a fixed-price quote before any work begins — no surprises.
Making Tax Digital is HMRC's programme requiring businesses to keep digital tax records and file using compatible software. MTD for VAT is already mandatory for most VAT-registered businesses. MTD for Income Tax (ITSA) is being phased in from April 2026. We handle full MTD compliance for all our clients using Xero, QuickBooks, and FreeAgent.
Cloud accounting software helps you record transactions — but it doesn't interpret them, spot tax-saving opportunities, or ensure your filings are correct. Our clients use Xero alongside our service: the software does the data entry, we do the thinking.
HMRC's R&D Tax Relief scheme allows UK companies to claim back a portion of their innovation spending — including software development, product testing, and process improvement. Many SMEs qualify without realising it. We assess eligibility as part of our annual accounts process at no extra charge.
Most client handovers are complete within two weeks. We contact your previous accountant directly to request all records and handle the professional clearance process. You don't have to chase anyone.
Yes. Pinnacle Accountancy Partners is a member firm of the Institute of Chartered Accountants in England and Wales (ICAEW). ICAEW membership requires strict continuing professional development, insurance, and compliance with the ICAEW Code of Ethics. Full regulatory details are available on the ICAEW Find a Firm register.
We process payroll on a schedule agreed at onboarding — typically 3–5 working days before your chosen pay date. You receive BACS-ready payment files, employee payslips, and a payroll summary on the same day. RTI submissions to HMRC are made on or before the payment date.
We support Xero (where we hold Platinum Partner status), QuickBooks Online, and FreeAgent. Most new clients use Xero, and we include initial setup and migration at no extra cost. If you use a different platform, speak to us — we're flexible.
We price everything as fixed monthly or annual packages. You agree the price upfront and that is what you pay — no hourly billing, no surprise invoices. If your business changes significantly during the year, we'll talk to you before changing anything.
Yes — and it's one of the most frequent questions we get. The right structure depends on your income level, risk profile, and future plans. We run through the numbers with you as part of your initial discovery call, so you can make an informed decision before committing to anything.
