InfoPlus vs ShipMonk: Which is best for you?

More modern integrations could really enhance productivity.

The biggest frustration I have run into is that they cannot use certain critical settings for our account without affecting their other customers - i.e. adding the same item twice on an order.

Their fulfillment is quite fast, 1-2 day processing and shipping, we ship a large volume and they are still able to keep up.

Custom projects take forever, ofter months. If you ever want to leave the process to get your goods out of Shipmonk takes 6+ months and they will charge you minimum fees, + storage fees the whole time and will never address any billing issues.
