FAQ
Expert Accountancy & Financial Reporting FAQ
What is the difference between IFRS and UK GAAP?
IFRS (International Financial Reporting Standards) are used globally, whereas UK GAAP (Generally Accepted Accounting Practice) is the body of accounting standards used in the UK. AcumenAGC provides expert guidance on which framework is most appropriate for your entity.
Do I need management accounts if I already do annual accounts?
Yes. While annual accounts are a statutory requirement, management accounts provide real-time data throughout the year, helping you manage cash flow and make strategic pivots before year-end.
How do I switch to AcumenAGC from my current accountant?
Switching is seamless. We handle the entire professional clearance process and request all necessary historical data from your previous firm.
Can you help with emergency accounting support?
Yes. If you have missed deadlines or have a backlog of records, our emergency accounting support team can quickly reconcile your books and bring you back into compliance with HMRC.
Are your services HMRC compliant?
Absolutely. All our processes are designed around current UK tax legislation and Making Tax Digital (MTD) requirements.
