Frequently asked questions
- Are these business and finance tools really free?
- Yes — every tool on this page is free, with no signup, trial or watermark. Hosting and time are paid for by unobtrusive ads.
- Do my invoices and customer details get uploaded?
- No. The whole cluster runs 100% in your browser. The invoice generator stores your business profile (logo, name, bank details) in localStorage on your own device only — nothing is sent to our server.
- Can I export an invoice as a real PDF?
- Yes — the invoice and quote generators use your browser's print engine. Click "Download as PDF" (or Print) and save as PDF from the print dialog. The result is a clean A4 document with no toolbox4free branding.
- How accurate are the financial calculators?
- All formulas are deterministic and unit-tested. Margin = (sale − cost) / sale, markup = (sale − cost) / cost, break-even = fixed / (price − variable), ROI = (gain − cost) / cost, ROAS = revenue / spend, MRR = sum(plan.price × subscribers).
- Does the UTM builder save my campaigns?
- No — UTM links are generated locally in your browser and not stored anywhere. Copy the link, save it in your campaign tracker of choice, then close the tab.
