At CSG, we’re proud to be at the forefront of helping accountancy firms make the most out of their AI strategy through the power of Microsoft Copilot, helping them transform tax compliance and audit workflows. Embedded within familiar Microsoft 365 apps like Excel and Teams, Copilot automates repetitive tasks, accelerates data processing and strengthens regulatory adherence, all of which are key priorities for our clients operating in high-pressure financial environments.
Transforming tax advisory with ai

Tax teams face relentless legislative changes and rising client expectations. That’s why we support firms in deploying AI-powered solutions like PwC UK’s tax assistant, which uses Microsoft Copilot to deliver real-time updates on tax rules and case law. This tool supports over 2,000 staff by cross-referencing internal databases to ensure accuracy and transparency, capabilities we help our clients replicate and scale.
Our consultancy has also supported firms adopting EY’s tax Copilot, which uses Azure OpenAI and Power Platform to build low-code solutions. These tools have improved efficiency across tax reporting and payroll operations, an approach we actively promote to help our clients stay ahead of regulatory complexity and deliver superior client service.

Security, oversight and integration: our approach
Security is crucial when handling sensitive financial data. Copilot operates within Microsoft 365’s secure framework, offering encryption, multi-factor authentication and detailed audit trails. At CSG, we ensure these protections are fully integrated into your environment.
It’s important to also emphasise the importance of human oversight. AI should augment, not replace, professional judgement. We help firms like yours strike the right balance between automation and expertise.
Integration with legacy ERP and accounting systems is another critical success factor. Our team ensures seamless deployment of cloud-native Copilot solutions that support scalability and hybrid work. We also provide tailored staff training to ensure AI outputs are interpreted correctly and used effectively.
Driving competitive advantage with ai
Copilot is continuing to grow as a key driver of digital transformation. At CSG, we help our clients lead this change through automating tax filings, expediting audit documentation and embracing regulatory knowledge to meet rising expectations.
