About

BillingEngine is cloud invoicing and accounting software for freelancers and small businesses. It creates electronic invoices in ZUGFeRD and XRechnung formats compliant with EN 16931, and every plan includes an unlimited email inbox for incoming e-invoices. Accepted quotes can become invoices, reminders can be sent at several dunning levels, and receipt recognition extracts amounts, dates, tax rates and suppliers before matching receipts to expenses. Data exports are available in DATEV, CSV, XLS, XML and PDF formats; listed integrations include DATEV export and a REST API for customers, invoices and payments. The free plan costs 0.00 EUR per free, billed monthly, and allows three invoices, three quotes and three receipts per month for one user. Basic costs 6.00 EUR per month plus VAT and allows 30 of each monthly for two users. Premium costs 12.00 EUR per month plus VAT and provides unlimited invoices, quotes and receipts for five users. BillingEngine says data is encrypted in transit, stored on servers in Germany and archived in a GoBD-compliant manner.
