Every project starts with a free call and a fixed quote, so you know the price and delivery date before any work begins. Prices below are typical starting points.
“We rebuild the same report by hand every month.”
Turn a report you rebuild by hand every month into a one-click refresh.
Starting price covers one recurring report built from up to 3 source files.
“My file is broken, slow, or only one person understands it.”
Broken, slow or confusing file? I'll make it reliable again.
Starting price covers fixing what's broken in one workbook. A full rebuild is quoted separately.
“I can't see how the business is doing without digging through sheets.”
See how the business is doing at a glance, without digging through sheets.
Starting price covers one dashboard page with up to 8 KPIs, built from up to 3 source files, data preparation included.
“Our needs change every month and we have no one to ask.”
Up to 5 hours a month for changes, small new reports and questions.
Unused hours don't roll over. Larger new reports are quoted separately.
“My team loses time because they don't know Excel well.”
Hands-on, remote sessions that make your team faster in Excel.
Starting price covers standard practice files. Exercises built on your team's own files are quoted separately.
You get the exact price in writing before any work starts, and it doesn't change unless you change the scope.
Prices exclude VAT. Croatian clients pay 25% VAT; EU businesses with a VAT number are invoiced under the reverse charge; clients outside the EU pay no VAT.
Before NonStopExcel I spent four years at KPMG on financial models, due diligence and procurement reporting, and nearly seven years at Hrvatski Telekom (Deutsche Telekom group). If your team needs a reporting process rebuilt, a model reviewed or data from several systems brought together, I can work within your procurement process: NDA, purchase order and invoicing included.
A typical larger project: for a telecom operator I connected SAP, data-warehouse and Access sources into one consistent management report and cut reporting time by 70%. Projects like this are quoted individually.
How it works
Tell me what's slowing you down. I'll ask about your data, your report and what “done” looks like.
Scope, price and delivery date in writing. You decide, with no obligation.
Fixes in a few days, automations and dashboards in 1–2 weeks, with a check-in along the way.
Short video and notes, a revision round included, and optional support afterwards.
Every project gets a fixed quote after a free 20-minute call, so you know the price before any work starts. No hourly billing, no surprises. The starting prices cover a clearly defined job; more data sources, messy data, complex business rules or extra deliverables raise the quote. Quotes are in euros, or in US dollars for clients outside Europe, and exclude VAT where it applies.
Yes. I'm a CISA-certified information systems auditor and have led IT audits for banks, including a central bank. I sign an NDA on request, work under GDPR from the EU, and delete your files when the project ends. You can also share anonymised or sample data.
We agree on what “done” means before I start, and every project includes a revision round. The job isn't finished until the file does what we agreed.
No. I build in the Excel you already have (Microsoft 365 or Excel 2016 and newer), using built-in tools like Power Query, PivotTables and, where needed, VBA.
Yes. Files are built to be understood, not just to work. You get a short handover video and notes, and as a former IT lecturer I make sure the people using it know how.
Remotely. We start with a video call, you share files by email, OneDrive, SharePoint or Google Drive, and I keep you updated until delivery.
Yes. I spent four years at KPMG and nearly seven at Hrvatski Telekom (Deutsche Telekom group). NDAs, purchase orders and invoicing through your procurement process are all fine.
