Implementation and migration

From source systems to one reliable number.

A new EPM system, or moving from Oracle HFM to OneStream? I translate what finance needs into a solution that works: data model, consolidation, reporting and the link with your ERP. No thick stack of requirements that ends up in a drawer, but building together and showing results early.

Application management and support

A calm close,
every single month.

An EPM system is never finished. New entities, a different chart of accounts, an acquisition, an auditor with questions. I keep your application healthy and I am there during the month-end close, exactly when it matters.

Track record

From London to Zaandam. Always at the table.

Head offices and group reporting teams in retail, animal nutrition, logistics and telecom. Since 2021 directly as Lemofa, before that through consulting partners.

Before Lemofa: projects in FMCG, banking, insurance and fashion during my time as a senior EPM consultant at inlumi, Infratects and The Hackett Group.

"I like to sit next to the client."

Fifteen years of EPM, from Sara Lee to Ahold Delhaize. Some consultants prefer to build once you hand them a stack of requirements. I belong to the other group: the people who sit at the table, translate what the client needs into a solution and advise along the way. And when things get stuck, I am the oil that keeps the team running.
