FAQ

Common questions

How do I get my template after buying? +
You'll receive a download link by email immediately after payment. You can also re-download any time from your order confirmation.
Do I need a specific version of Excel? +
Templates work with Excel 2016 and newer, as well as Google Sheets (free). If you run into any issues, just reach out and I'll help you get it working.
Can I edit and customize the templates? +
Yes — all templates are fully editable. You can change colors, add your logo, rename categories, and adjust formulas to suit your business.
What if I need something custom? +
Head to Services or Contact and tell me what you need. Custom spreadsheets start from €150.
Can buyers share their license with others? +
Each license key activates on 2 devices maximum (for example your PC and laptop). After that, the key cannot be activated elsewhere. Keys are validated on our server, not in the browser alone. Sharing a key beyond your own devices will hit the limit quickly.
What do I get when I buy a Pro app? +
Both formats in one purchase: the Windows .exe desktop app and the HTML browser version. After checkout you receive a license key by email. Enter it on the unlock page to access both. Pro HTML pages and .exe downloads stay locked until then. Free apps (Cash Flow, Rate Estimator, Invoice AI) stay free with no key.
Windows warned me about the .exe — is there another option? +
Yes. Unsigned .exe files often trigger a one-time SmartScreen warning (More info, then Run anyway). After you buy a Pro app, you can use the HTML version in your browser instead of downloading the .exe — both are included in your purchase. Free tools also have open HTML versions on the Free apps page.
Is there a refund policy? +
Yes, 100% money-back guarantee. If a template doesn't work for you, email [email protected] within 14 days for a full refund.
