Sector experts

We’ve worked with accountancy firms, so we understand the unique challenges accountants face.


Focussed on you

We explore your business needs first, and IT second, so the products and services we provide are tailored to your exact needs.

Working with you to maximise your investment in technology



We’ll help you unearth and understand your current state, challenges, and objectives from both a strategic and tactical perspective. We’ll then share our initial findings and suggest improvements to help you:

• Consolidate and reduce expenditure
• Adapt to and embrace a secure modern workplace environment
• Empower staff productivity through system uptime (availability), knowledge (training), automation, and support.



Taking the outputs from the Discovery session, we’ll work with your strategic and operational teams and the relevant experts across TSG to design your solution and then agree on an implementation and onboarding process that supports a smooth adoption for your organisation and people.



Physical implementation is one thing, however, TSG’s communication onboarding plan helps guide and support your people’s adoption to get the most out of your investment.



Our partnership doesn’t end here. Your dedicated Customer Success Manager will proactively develop the ongoing relationship by:

• Regularly reviewing performance
• Driving continual service development
• Identifying changes in the market

At TSG we have experience with a variety of popular software solutions, including a range of accounting and payroll software. We can help you host and maintain your current applications, or advise on alternative options that might fit your needs better.

Accountants handle a range of sensitive client information, so data security is paramount. We’re well-versed in supporting accountancy firms with cybersecurity, and can help you implement simple processes to keep your clients’ data safe and stay GDPR compliant.

While the right technology is vital (and we’re experts in this), most data breaches happen as a result of human error. That’s why we work closely with you to understand your internal processes, identify potential risk areas, and implement simple changes to keep sensitive data safe.
