How Mathema Replaced a $250 Excel Mistake With Daily Financial Control
“I was lucky with my finances, I always listened to smart people, and they all said: control your finances.”
— Vitalii Shkil, Co-founder, Mathema
Challenge
Mathema is an online math school that today runs more than 20,000 lessons a month for upward of 2,000 students. It didn't start that way, and it didn't start on Finmap either — co-founder Vitalii Shkil built the company's early finances in Excel, the way most founders do. It worked, until scale caught up with it. The spreadsheets that were supposed to give Shkil a complete financial picture never quite delivered one — updates lagged, and the business paid for it in ways that were hard to see coming. In one incident, an error inside an Excel formula lost the business $250, and it took the team two hours of searching just to find where the number had gone wrong.
For Shkil, that kind of gap mattered more than it might have for a first-time founder. He came into the business already carrying financial-accounting knowledge, and he wasn't willing to let a spreadsheet be the ceiling on how well he could apply it. "I was lucky with my finances, I always listened to smart people, and they all said: control your finances," he says.
Solution
Since March 2021, Mathema has run its financial management on Finmap. Shkil connected the company's bank accounts so transactions post automatically instead of being typed in by hand — closing off the manual-entry step where the $250 error had crept in. He also set up role-based access across the team, so people could log and see the numbers relevant to their part of the business without every account holder needing full financial visibility.
The daily habit is cash flow monitoring — a same-day view of what's moving in and out, replacing the delayed, error-prone picture Excel used to give him. On top of that daily check, Shkil reviews a monthly P&L and cash flow statement, and tracks first-lesson payments specifically, since that metric tells him whether new students are actually converting into paying ones rather than just signing up. He uses the same numbers to keep Mathema's cost structure under regular review, looking for categories worth optimizing as the school scales. "I was already applying my knowledge of financial accounting to a new business, making it financially healthy from the start," he says.
Results
Mathema has grown into a school running more than 20,000 lessons a month for over 2,000 students, with financial reporting that no longer depends on someone remembering to update a spreadsheet correctly, or catching an error before it costs real money. Under the daily cash flow discipline Shkil built around Finmap, the company reports it has never fallen into a cash gap — the exact kind of blind spot that cost the business $250 and two lost hours back when Excel was the whole system.
For Shkil, the choice of tool was never purely financial. "I also want to support cool Ukrainian products like Finmap," he says.
