A lot of 3PL relationships start well and quietly fall apart over the same issue: the brand does not actually know what is happening with their own inventory once it leaves their hands. Not necessarily because the 3PL is doing a bad job, but because nobody set expectations upfront about what information the brand would get, how often, and in what format.
This is not a small or rare problem. The 2025 Third-Party Logistics Study, conducted by NTT Data, Penske Logistics, and Penn State University, found that shipper satisfaction with their 3PL relationships dropped to 89 percent, down from 95 percent the year before. A separate industry survey from Inbound Logistics found that concern about supply chain visibility jumped 12 points in a single year, and that failed expectations have become the single biggest reason 3PL partnerships fall apart, cited by 29 percent of shippers, up sharply from 17 percent the year prior.
Read together, those numbers point to the same root cause. It is not usually a catastrophic failure that breaks a 3PL relationship. It is the slow accumulation of not knowing what is going on.
What good reporting actually looks like
Real-time inventory visibility, not a weekly export. You should be able to check current stock levels whenever you need to, not wait for a scheduled report or send an email and wait for a reply. If checking your own inventory requires contacting your 3PL directly, that is a visibility gap that will eventually cost you.
Order status at the individual order level. You need to know where a specific order stands, whether it is received, picked, packed, or shipped, without having to ask. This matters most when a customer contacts you asking where their order is, and you have no way to check without going through a middleman.
Shipping and fulfillment accuracy metrics. On-time ship rate, order accuracy rate, and any recurring error patterns should be visible to you on an ongoing basis, not something you have to request after a problem already happened.
Returns processing detail. How quickly are returns processed once they arrive at the warehouse, and how is that inventory handled? Is it restocked, inspected, or written off? A 3PL that cannot answer this clearly is probably not tracking it closely either.
Receiving and inbound shipment confirmation. When new stock arrives at your 3PL, you should know it has been received and counted within a reasonable window, not discover a discrepancy weeks later when you go to check stock levels.
Storage and billing transparency. You should be able to see what you are being charged for and why, tied to actual activity, not a lump invoice you have to take on faith.
Questions worth asking before you sign
- How do I access my inventory and order data, and how often is it updated?
- What happens if there is a discrepancy between what I think I have and what you show?
- Can I get this data through an API or dashboard, or only through email requests?
- How quickly are receiving discrepancies reported back to me?
- What does your standard reporting package include, and what costs extra?
If any of these questions get a vague answer, that is worth paying attention to before you sign a contract, not after you are locked into one.
Why this matters more as you scale
At a smaller volume, gaps in reporting are annoying but survivable. You can usually catch a problem by manually checking or asking. Once you are running larger order volume, or selling across more than one channel, a lack of real-time reporting from your 3PL becomes one of the direct causes of the multi-channel inventory chaos covered in an earlier post. You cannot keep your own numbers straight if the 3PL holding your physical inventory cannot tell you accurately and quickly what is actually there.
Good reporting is not a nice-to-have add-on. It is the foundation that everything else- buffers, reorder points, multi-channel sync- is actually built on top of.
