Billing turns the paper bills you get anyway into a private, searchable one
expense log — without sending your data to anyone.

Scan the QR code from any Serbian fiscal account and the Expense Calculator takes over everything
data directly from the Tax Administration portal (suf.purs.gov.rs): seller, date,
items, taxes and total amount. Everything is stored locally, in an encrypted database at
your phone. No account, no cloud, no tracking.

WHY COST BUDGET

• Privacy first — all data stays on your device, encrypted
(AES-256). We don't have a server and we don't collect anything.
• Quick capture — scan the QR and you're done; manual entry as backup.
• You never lose your receipt — even if the seller hasn't posted the item yet
Taxes, the bill is saved, and the items are automatically replenished later.

KEY FUNCTIONS

PRIVACY

Billing has no ads, analytics, or third-party tracking. The only one
the internet connection it makes is directly to the official portal of the Tax Administration
readings of the bill you scan. Privacy Policy:
