Younium is a great service to manage subscriptions, sales, and the invoicing thereof. It is very user friendly, and has great integrations with both our CRM system (Microsoft Dynamics) and our accounting system (PE Accounting). Review collected by and hosted on G2.com.
The downside that I have so far encountered is that it is not possible to credit the same invoice more than once, so when I first had to partly credit an invoice, and then later needed to credit the rest after long discussions between our company and the client, I could not credit the remainder as I had already credited a part of it.
