4invoices — invoicing for Australian businesses
4invoices is the invoicing core of the 4b2b ecosystem, tuned for the Australian tax environment. Validate counterparty ABNs against the ABR live, generate compliant tax invoices with GST line items, export BAS-ready reports, and send Peppol e-invoices for B2B and B2G workflows. Recurring billing, multi-currency support, Stripe, Eway and bank-transfer reconciliation are all built in. For accounting firms, the platform exposes a multi-tenant view that scales from one client to several hundred without the per-seat costs of bigger products.
