Open BillKit GST, go to the paywall or Settings, and tap Unlock BillKit Pro. If you already paid (for example on another device or after reinstalling), tap Restore Purchase to recover it. Pro is a one-time payment — there is no subscription.
This usually means the App Store couldn't load product details (often a brief network hiccup). Make sure you have an internet connection, fully close and reopen the app, and try again. If it persists, email us and we'll help right away.
BillKit GST works fully offline. Your business and document data stays on your device — there is no account, no server, and no analytics. Data leaves your device only if you choose to export or share a PDF yourself.
No. BillKit GST is a record-keeping and document-creation tool only. It does not file returns and is not a substitute for professional tax advice. Please verify all figures with your CA or tax advisor before filing.
