About

Olvatra is a one-person shop run by a software developer in Brno, Czech Republic. I build the spreadsheets I wish existed when I was tracking client work and campaign numbers myself.

How the templates are made

Each template starts with a real job: planning posts, chasing invoices, judging a creator campaign. The formulas are written so you can read them, and every file is recalculated and checked for errors before release. Example rows show you the format, and a "Start here" tab explains the file in one page.

I use AI tools to help draft guides, product text and example data. Every formula is tested and every page is checked before it goes live.

Something broken or missing?

Email [email protected]. If a formula is wrong, you get a fixed file. If a template is missing something you need, tell me: that's how the next version gets planned.
