Edinburgh (Edinburgh Daily) July 13, 2026 – AMS Accountants Group has appointed a new Edinburgh partner to spearhead its outsourced accounting offering as the fast-growing firm accelerates its expansion across Scotland. Sean Dunn has joined the Manchester-headquartered accountancy and advisory business as partner and head of outsourced accounting, leading the firm’s Edinburgh operation from its new base at Lochrin Square in the city’s Exchange District.

How is AMS building a £20 million Scottish business?

The appointment comes as AMS looks to build a £20 million Scottish business following its expansion north of the border. The firm said it had already secured agreements with three clients ahead of its formal Edinburgh launch, including one Edinburgh-based business, generating annual revenue of more than £200,000. AMS is also in discussions with two UK-wide businesses, one of them headquartered in Edinburgh, over outsourcing their finance functions and said it has a further pipeline of 10 potential clients.

As reported by the firm’s own announcement, Steven Fraser, regional managing partner for Scotland, added: “When we launched in Scotland, we made a commitment to build something meaningful – not simply plant a flag and move on. What we did in Aberdeen with Infinity Partnership showed exactly what that looks like in practice, and Edinburgh is the next chapter of that story.”

What roles will Sean Dunn perform at AMS?

Alongside leading the Edinburgh team, Dunn will establish and head a new national outsourced accounting service for AMS, providing financial compliance, operations, planning and strategic finance support to businesses across the UK. The Edinburgh office marks the latest stage of AMS’s Scottish growth strategy following its acquisition of Aberdeen-based Infinity Partnership, which established the firm’s Scottish headquarters.

AMS said it plans to replicate that model in the capital, with further senior hires expected across audit, tax and advisory. Sean Dunn said: “Too many businesses still treat finance as a cost centre, something to be managed down rather than invested in. The reality is that poor financial control creates real risk, and the cost of getting it wrong almost always outweighs the cost of getting it right. What we’re building at AMS is different. It’s not about parachuting in a resource and stepping back – it’s about being a genuine partner to the businesses we work with.”

How many jobs does AMS plan to create in Scotland?

The growth plans have prompted recruitment, with two Edinburgh-based roles currently being advertised as part of a wider ambition to create around 200 jobs across Aberdeen, Edinburgh and Glasgow. The firm’s public communications indicate that the Edinburgh launch is being treated as a strategic scaling point rather than a one-off office opening, with the expectation that senior hires will follow across core service lines.

Steven Fraser noted that “Sean’s appointment gives us a strong, senior presence in Edinburgh while also adding a capability the wider AMS business has not had before. The fact we already have clients signed, revenue generating and a strong pipeline ahead of our formal launch shows how the market is responding.” This suggests that the firm views the Scottish market as a core growth area rather than a peripheral extension.

What is Sean Dunn’s professional background?

He joins the firm after more than a decade in outsourced accounting and advisory, having previously held senior roles including head of operations at a boutique firm and director at a top-five accountancy practice. His experience spans both specialist boutiques and larger, established practices, giving him exposure to different operational models and client expectations.

According to the firm’s announcement, Dunn’s track record includes leading operations teams, managing complex client finance functions, and working on advisory projects that support strategic decision-making. This background aligns with AMS’s stated emphasis on treating finance as a strategic investment rather than a purely transactional service.

How does the Edinburgh office fit into AMS’s Scottish strategy?

The Edinburgh office marks the latest stage of AMS’s Scottish growth strategy following its acquisition of Aberdeen-based Infinity Partnership, which established the firm’s Scottish headquarters. AMS said it plans to replicate that model in the capital, with further senior hires expected across audit, tax and advisory.

As reported by the firm, the Infinity Partnership acquisition allowed AMS to establish a foothold in Aberdeen and build a regional presence before expanding into other Scottish cities. The Edinburgh base at Lochrin Square is intended to follow the same pattern: a central location in the Exchange District, a partner-led team, and a focus on outsourced accounting as a core offering.

What do early client results suggest about market demand?

The firm said it had already secured agreements with three clients ahead of its formal Edinburgh launch, including one Edinburgh-based business, generating annual revenue of more than £200,000. AMS is also in discussions with two UK-wide businesses, one of them headquartered in Edinburgh, over outsourcing their finance functions and said it has a further pipeline of 10 potential clients.

These early results indicate that Scottish businesses are already responding positively to AMS’s outsourced accounting model, particularly in the capital. The firm’s public statements suggest that the Edinburgh launch is being treated as a strategic scaling point rather than a one-off office opening, with the expectation that senior hires will follow across core service lines.

Background of the Edinburgh Partnership Development

AMS Accountants Group is a Manchester-headquartered accountancy and advisory firm that has been expanding its presence across the UK over recent years. Its entry into Scotland began with the acquisition of Aberdeen-based Infinity Partnership, which became the firm’s Scottish headquarters and provided an established local platform for growth.

The Edinburgh partnership, announced in July 2026, is designed to replicate the Aberdeen model in the capital. Sean Dunn’s appointment as partner and head of outsourced accounting is central to this strategy, as is the establishment of a new national outsourced accounting service that will operate across the UK. The firm’s stated ambition is to build a £20 million Scottish business, supported by a pipeline of clients and a recruitment plan that aims to create around 200 jobs across Aberdeen, Edinburgh and Glasgow.

What could this development mean for Scottish businesses and professionals?

For Scottish businesses, the expansion of AMS’s outsourced accounting service could increase the availability of high-quality finance support, particularly for firms that do not wish to maintain large in-house finance teams. Sean Dunn’s emphasis on treating finance as a strategic investment rather than a cost centre may encourage more companies to engage external providers for compliance, operations, planning and strategic finance work.

For accountants and finance professionals in Scotland, the plan to create around 200 jobs across Aberdeen, Edinburgh and Glasgow suggests new career opportunities in audit, tax, advisory and outsourced accounting roles. The firm’s model of partner-led teams and long-term client partnerships may also influence how local practices structure their own service offerings, potentially raising the bar for client engagement and strategic support.

Over time, if AMS succeeds in building a £20 million Scottish business, the firm could become a significant player in the Scottish accountancy market, with the potential to influence pricing, service standards and the availability of specialised outsourced accounting services across the region.
