Free diagnostic

Power BI for companies in Serbia

See where your money leaks before your accountant closes the month.

We connect your POS, accounting and payroll into one Power BI report that refreshes itself. You open your phone and see revenue, margin and costs per location today, not on the 20th.

No commitment. The diagnostic is free and stays yours even if we never work together.

For accounting firms

Your clients ask you "how am I doing". You have the data but no tool to answer in three seconds. We are that tool, under your recommendation.

  • A free report for your own firm: clients, revenue, deadlines, who is late with documents.
  • 10 to 15% of every client you refer, for as long as they stay a client.
  • Your client stays yours. We do not do bookkeeping and never will.
Book 20 minutes

What it looks like in practice

A client sends you a question about margin. Instead of building a spreadsheet, you send a link. The report pulls data from your software overnight; you do nothing extra, and your client sees they have the best accounting firm in town.

Who is behind this

Uroš, FP&A and controlling. I have run reporting and analysis for a portfolio of clients ranging from restaurant groups to international insurance, joined POS, payroll and accounting into one picture, and built dashboards that owners actually open. Computer science graduate, RAF Belgrade.

SumiCo Data works from Belgrade for companies across Serbia and the region. Call, Teams or on site, whichever suits you.

What we are not

  • We are not accountants and we do not replace yours.
  • We do not sell software or licences.
  • We do not build dashboards nobody opens: if you are not using it, we will be the first to say so.
