Part of the Lockstep Suite, Self-Service is a free product. Companies can give customers access by sending an email containing a Self-Service Link, which allows them to see statements, individual invoices, past history and make payments.  Lockstep, which was purchased by Sage last year, is described as a connected accounting network for automating accounting workflows between companies. Those interested can sign-up for Self-Service for Free. The service integrates a user’s ERP with the Lockstep inbox.
