Founder · Billingz
Dr. Radovan Vitosevic.
I’m building Billingz, a financial control system for freelancers and small businesses. Before that, more than eighteen years in finance and corporate leadership, at executive and board level. I have worked directly in a dozen countries, leading big international teams.

Founder thesis
Why I’m building this.
The people closest to the money had the least clarity about it.
I have worked directly with hundreds of independents and small businesses: promoters, creators, e-commerce brands. The money is real, but it is variable, and the niche sells a luxury life as the whole point. Time and again I watched people earn well and still lose control, spending against an unpredictable future with no financial discipline and no clear read on where they actually stood.
On the other side, I worked hands-on with hundreds of small and medium businesses, building loyalty programs and customer-management tools, running key account management and sales.
The same gap showed up everywhere I looked. Tools were built for accountants, not operators. Spreadsheets demanded discipline no one had time for. And the one question that actually matters - am I safe right now - never had a clean answer.
Billingz is the answer. Keep earning, and finally have clarity and control over your finances and your financial future. Not another invoicing tool, not another dashboard, but one place that turns scattered money events into one clear picture and shows the next step before it costs you.
