Case Study: Bumper streamlines close and controls with Stacks

How Bumper Is Upleveling Close & Controls with Stacks

Bumper, the UK’s leading automotive payment platform, faced challenges in maintaining a structured and efficient finance function to keep pace with its rapid scaling across markets, entities, and currencies. Finance Director Alfie Sansom sought better tools to empower his team and ensure finance was an enabler for growth, not a blocker. This led them to partner with Stacks to uplevel their close and control processes.

Stacks implemented a collaborative workspace that brought structure to Bumper’s month-end close and reconciliations, assigning clear owners and due dates. The solution included Stacks' Excel Assistant to streamline journal entries. As a result, over 80% of balance sheet accounts were reconciled in Stacks within the first month, and 90% of journals are now posted via the Excel Assistant. The team achieved full audit readiness with documented evidence and review history for every task.
