VirtoSoftware has the ability to thoroughly study the case and then create a road map and plan to assist and developing a Migration Solutions to move to SharePoint Online.
I am very grateful to all the Virto Team for their help and support throughout this process.
Implementing Virto Calendar for SharePoint Online was a no brainer for my team. After a free trial, we quickly saw what an amazing solution it is. We have been able to extend SharePoint's out of the box calendars with this app to create beautiful, interactive calendars. We even developed a conference room booking system for one of the premier sporting facilities in the US, based on the features available with Virto Calendar. The Virto team is also very quick to add new features to the application. I have seen it evolve over the past 2 years into an app we just can't live without. It seems they listen to their customers and implement the features that are needed most and lacking in the default SharePoint calendaring experience. I could not recommend a better app for SharePoint online calendaring.
We were looking for Sharepoint solution and we came across VirtoSoftware. While testing it, they provided great support and eventually we went ahead with the purchase. There are many SharePoint vendors out there but one of the things we look out for is before & after-sales support, VirtoSoftware provided a great product and delivered good service. They would come to mind if we need any sharepoint solutions again.
