Where documents come from

Every source, one inbox.

Peppol is the spine. WhatsApp and manual entry fill the gaps. Each source is colour-coded so you know what's trustworthy at a glance.

Peppol

Invoices in, invoices out — UBL 380 & 389.

Upload

Snap a receipt on WhatsApp, it lands here.

Manual

Old-school entry, flagged for review.

Software-assisted, not tax advice.

Accounticus's answers are software-assisted information about your own books — never sold as tax advice. The accounting engine stays Odoo/OCA; the compliance logic stays pure-Python under the AGPL boundary. Your books remain yours.
