From Reykjavik to London: How Prysm Financial Supported Tommi’s UK Expansion

By 07/10/2026No Comments2 min read

Tommi’s Burger Joint is an Icelandic-founded burger chain famously credited with keeping global fast-food giants out of Iceland.

Founded by Tomas “Tommi” Tómasson following a trip to America, the original joint became an instant success, selling an average of 1,000 burgers a day to Reykjavik’s population.

The Challenge: Navigating UK Expansion

Following a successful pop-up in Marylebone, Tommi’s launched its first permanent UK location on Thayer Street, London. While the brand had ambitious plans for further expansion, the directors lacked the clear financial visibility required to scale sustainably.

Streamlining the Finance Function

When Tommi’s partnered with Prysm Financial, their UK finance operations were completely re-engineered. Prysm eliminated slow, manual processes and clunky workflows, replacing them with a modern, automated system.

Leveraging deep expertise in the hospitality sector, Prysm implemented a suite of leading cloud accounting software—anchored by Xero as the central data hub. By integrating automated invoice processing and data extraction technology, manual data entry was minimized, drastically cutting bookkeeping time and ensuring real-time financial transparency.

Strategic Insights Driving Sustainable Growth

Tommi’s now receives comprehensive monthly management accounts shortly after month-end, providing an accurate, up-to-date picture of performance and profitability.

Beyond core accounting, Prysm delivers CFO-level strategic support. Regular director meetings focus on reviewing performance, benchmarking key operating metrics against hospitality industry standards, and identifying actionable opportunities to maximize revenues and margins.
