We've just announced support for electronic invoicing on the cloud based Free B2B Trading Gateway AS2Gateway! This allows users to invoice trading partners via EDIFACT INVOIC messages over AS2, using a simple and intuitive web interface
Recurrent invoicing is simplified as any invoice can be saved as a template and re-used multiple times. The AS2Gateway converts all the invoice details into an EDIFACT D93A INVOIC message right now, and soon will support the other versions, as well as X12 based messages such as the 810.
In the near future, the platform will add support for parsing and generation of more message types, which will allow users to easily generate an invoice based on a purchase order received; or an advanced shipping notification (ASN) etc.
The AS2Gateway offers a free tier to support most SMEs that are required to electronically invoice trading partners for payment. For larger users, a premium tier is available with advanced options (to be announced shortly!), and for retailers or large corporations, the AS2Gateway is available for on-premise private deployment.
