Answers to common questions

Is an Inkbill invoice an official tax document?

No. Inkbill creates commercial invoices and quotes. Where your country requires official e-invoicing (for example NFS-e in Brazil), issue that through your government's system.

How are invoice numbers assigned?

When you mark a document as sent. Change the format in Settings › Numbering; existing documents keep their numbers. If two devices ever create the same number while offline, Inkbill shows a banner with a Renumber action.

How do I sync between my devices?

With Inkbill Pro, turn on Settings › Sync on each device, signed in to the same iCloud account. Your data stays in your private iCloud.

I bought Pro but it isn't active

Open Settings › Pro and choose Restore Purchases while signed in to the Apple Account you used to buy it. Family Sharing members get Pro too.

What happens if Pro ends?

Nothing is locked or deleted. Sync pauses and your data stays on the device; only creating beyond the free limits needs Pro again.

How do I back up my data?

Settings › Data › Back Up saves everything to a JSON file. Restoring adds missing items and updates matching ones; it never deletes.

How do I cancel a subscription?

Settings › Pro › Manage Subscription, or in your Apple Account subscription settings.
