SumUp, the UK-based fintech widely known for its payment terminals and card readers aimed at small and medium-sized merchants, announced in December 2025 that deposits held in its merchant Business Account product had surpassed €1 billion. The platform simultaneously reached 1.5 million active Business Account users worldwide, a pair of milestones that together underscore the company's deepening and increasingly credible push into embedded banking services beyond the payments hardware that originally defined its brand.
The Business Account product sits at the centre of SumUp's longer-term strategy to evolve from a payments acceptance provider into a fuller financial operating system for its merchant base. Crossing the €1 billion deposit threshold is commercially significant because it signals that merchants are not merely routing card transactions through SumUp's terminals but are also holding meaningful financial balances within the ecosystem — a critical prerequisite for building a durable and diversified banking services business on top of the payments foundation.
REVENUE TRAJECTORY AND EBITDA POSITIVE SINCE 2022
SumUp's underlying financial trajectory provides commercial context for the deposit milestone. The company has maintained a positive EBITDA position since December 2022, demonstrating that its expansion into banking-adjacent services has not been pursued at the expense of basic operational profitability. Research firm Sacra estimated that SumUp reached approximately $600 million in annualised revenue in 2025, a figure that reflects both the breadth of SumUp's product range and the geographic spread of its merchant footprint across Europe and beyond.
Processing over one billion transactions annually places SumUp among the higher-volume payments operators globally within its market segment. That transaction volume base provides two mutually reinforcing advantages: it generates the proprietary data needed to assess merchant creditworthiness and behaviour, and it anchors the daily financial relationship with merchants in a way that makes consolidating banking activity within the same platform a natural and low-friction decision for business owners who already rely on SumUp for their payment acceptance needs.
EMBEDDED BANKING AS THE STRATEGIC PRIORITY
The 1.5 million active Business Account users represent a substantial and meaningful share of SumUp's total global merchant base, indicating that the cross-sell from payments acceptance into banking products has achieved genuine commercial scale rather than remaining a peripheral or pilot-stage feature. For SumUp, growing the deposit base diversifies its revenue mix away from transaction fees, which face competitive pressure and regulatory caps in several European markets, and into interest income and fee-based banking services that carry different and potentially more stable margin characteristics.
The €1 billion deposit figure also carries regulatory significance that SumUp will need to continue to manage carefully. As deposit-taking activity grows in scale, questions about the adequacy of the prudential and consumer protection framework under which SumUp operates become more pressing for European financial supervisors monitoring the expanding role of non-bank entities in mobilising retail and merchant deposits. The company holds payments institution licences across several markets, and the continued growth of its deposit base may intensify scrutiny from national competent authorities responsible for oversight of embedded finance providers operating at this scale. How SumUp navigates that regulatory dimension — and whether it seeks additional licences to bring its growing deposit-taking activities within a more comprehensive supervisory framework — may prove as consequential to its long-term trajectory as the commercial milestones it achieved in December 2025.
