Issues with a 3PL (Third Party Logistics) company you've had?

[BlackRabbit_TX]

Hello everyone, I'm new to this group and excited to learn more from fellow business owners.

I have a Third Party Logistics company called Black Rabbit 3PL that has grown a lot in our first year, but I'm trying to learn more about common issues that seem to arise with ecommerce companies that use 3PL's. So far so good for us, but obviously scaling up will expose some types of issues that share commonality between companies.

So my questions are:

- What negative issues have you have experienced with a 3PL? Were they ultimately solved? 

- Are there any services your current 3PL provides that you feel do not provide value? I know a lot just do straight fulfillment with no other additional services.

I'm just looking for some feedback to take forward and any and all input is greatly valued beyond words.

A million thank you's to you all for your time!
