Really bad service.
PandaDoc suddenly ended service without any prior communication, which caused a major outage for us. We discovered that it is because they required us to renew our subscription. After we signed up, service continued to work but STOPPED WORKING after a couple hours. During this time customer support is basically non-existent. Even when customer support responds (at most once per 24 hours), it's clear that customer support doesn't have any capability to solve any problems. We had to pay the subscription fee a SECOND TIME to unblock ourselves. Now we have to hunt down their billing team to get a refund.
