❓ FAQ
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Q: Does this quote generator also create invoices?

A: Yes — this is the core workflow. Create a quote, track its status (Draft → Sent → Approved), then convert to invoice in one click. All line items and client details carry across automatically. No re-entering anything.

Q: Do I need Excel, Google Sheets, or a Google account?
A: No. This is a standalone HTML file that runs in any modern browser. No spreadsheet software, no Google account, no Microsoft 365 needed.

Q: Does this invoice generator work without internet?
A: Yes — completely offline once downloaded. Open the file, it works. No Wi-Fi, no cloud, no server dependency of any kind.

Q: Can I set my own currency and tax rate?
A: Yes. Choose from USD, AUD, NZD, GBP, CAD, EUR and more. Set your own tax label (GST, VAT, Sales Tax, HST) and percentage in Settings.

Q: Will my data be lost if I close the browser?
A: No. Data saves automatically to your browser's localStorage after every change. Export a .json backup from Settings for extra peace of mind.

Q: Can I use this quote and invoice tool on my phone or tablet?
A: Yes — works on Android, desktop, and iPhone/iPad. Desktop (Chrome, Edge, Firefox) and Android users can open the file directly with no extra steps. iPhone and iPad users need one extra step: Apple restricts how local files save data in Safari, so you'll need a free app like "Discit" or "HTML Viewer Q" from the App Store to run FieldKit with full functionality.

Q: What if I get a new computer?
A: Copy the .html file across, export your backup .json, import on the new device. Everything transfers — clients, documents, settings, all of it.
