Canonical: https://www.softwareadvice.co.uk/software/558223/K-OS-Billing

> K-OS Billing is AI-powered invoicing and accounting software for SMBs, freelancers and accounting firms in Spain. Upload a photo or PDF and the AI classifies the document, extracts the data and calculates VAT automatically, with no manual entry. It is fully VeriFactu-compliant (Royal Decree 1007/2023): it generates chain-of-custody invoice records and reports to the Spanish tax agency (AEAT), validated and in production. It also includes automatic bank reconciliation, a tax engine that computes VAT, income tax and corporate tax (warning you before each deadline), accounting export, and a fiscal assistant that answers with verifiable citations from official sources. Built for accounting firms, it offers a multi-client dashboard to manage your whole portfolio, while your clients get a subsidised basic plan. Proprietary software, part of the K-OS ecosystem by Kavena Consulting. Plans from EUR 49.95/month + VAT, no lock-in.
