Trading partner onboarding
When a new customer or retailer comes on, we set up the connection. We work through their specs, build and test the maps, and get you certified so you can go live without weeks of back-and-forth.
EDI integration & optimization for 3PLs
EDI that keeps your 3PL shipping.
ReliantShip helps third-party logistics companies onboard trading partners, fix failed EDI documents, and connect their WMS to EDI so orders, receipts, ship notices, and invoices go through the first time.
Free, with no obligation. We'll look at where your EDI is breaking and tell you what we'd fix first.

3PL EDI services
Our main work is EDI for 3PLs. We also help with customs and trade compliance, because the two often show up on the same desk.
EDI integration and optimization for 3PLs
Mapping and failed-document cleanup
We find out why your 940s, 945s, 943s, 944s, 856s, and 810s are failing or getting rejected, fix the maps, and clear the backlog. Then we make sure the same errors don't come back.
WMS-to-EDI integration
We connect your warehouse management system to your EDI setup so order and inventory data moves both ways without anyone re-keying it or exporting spreadsheets.
Monitoring and support retainers
For a set monthly fee, we watch your EDI traffic, catch failures early, and handle partner changes and map updates as they come in. You'll have someone to call when something breaks.
Customs and trade compliance support
For 3PLs and their customers who handle imports and exports, we help with:
- Classification: HTS classification of products, with the reasoning written down.
- ACE/ABI: Questions about filing, data quality, and working with your broker.
- Documentation: Commercial invoices, packing lists, and the records you need to keep.
Common 3PL EDI problems we fix
- A big new customer wants to go live and their EDI specs are 80 pages long. We'll read them, build the maps, and get you through testing.
- 945s are failing and your customer is asking where their ship confirmations are. We'll trace the failures, fix the cause, and resend what's stuck.
- Your team is fixing EDI errors by hand every morning. We'll find the patterns behind the errors and fix them at the source.
- Your WMS and your EDI don't talk to each other. We'll connect them so data moves without copy and paste.
- Chargebacks for late or wrong 856s and 810s. We'll tighten your ASNs and invoices so they match what your partners expect.
- The one person who understood your EDI left. We'll figure out what's in place, write it down, and keep it running.
- Classification and import paperwork keep landing on someone who isn't a specialist. We'll take that on or train your people.
Why 3PLs work with ReliantShip
01
We focus on 3PLs.
Warehouse orders, receipts, shipment confirmations, ASNs, and invoices are the documents we work with every day. You won't have to explain what a 940 is.
02
You work directly with the specialist.
We're a small consultancy. The person who reviews your setup is the one who does the work. Your project won't get passed to a junior team.
03
We explain things plainly.
You'll know what was broken, what we changed, and why. We document our work so you aren't dependent on us.
04
EDI and customs under one roof.
Most EDI consultants don't know trade compliance, and most compliance consultants don't touch EDI. We do both, which helps when shipment data and customs data have to agree.
05
We start small.
Every engagement starts with a free 30-minute review. If we can't help, we'll tell you.
About ReliantShip
ReliantShip was founded by an EDI and trade compliance specialist based in New Jersey.
Our work is in the details of EDI and customs: building maps, onboarding trading partners, tracking down failed documents, and handling classification and import paperwork. We kept seeing the same thing at 3PLs. Good warehouse teams were losing hours to EDI problems that could be fixed, and they had no one dedicated to fixing them.
ReliantShip exists to be that someone. We're small on purpose, so we can stay close to the work and give each client direct, hands-on attention.
Common questions
What is a 945?
A 945 is the Warehouse Shipping Advice. The 3PL sends it to the customer after an order ships, confirming what went out, in what quantities, and how. If 945s are late or wrong, the customer's inventory and billing fall out of step with what actually left the building.
Which EDI documents do you work with?
Mainly the warehouse set: 940 (warehouse shipping order), 943 (stock transfer shipment advice), 944 (stock transfer receipt advice), 945 (warehouse shipping advice), 856 (ship notice / ASN), and 810 (invoice). We also handle the 997 acknowledgments that go with them.
How long does an EDI integration take?
It depends on the trading partner's specs, how fast their testing team responds, and what your WMS and EDI platform can already do. A single partner with clear specs can move quickly; a large retailer with strict certification takes longer. After the free review we give you a realistic timeline for your case.
Do you only work with 3PLs?
EDI for 3PLs is our main focus. We also help their customers and other shippers with customs and trade compliance, such as HTS classification and import documentation.
Do we need to change our WMS or EDI platform?
Usually not. We work with the systems you already have and only suggest a change if something truly can't do what your partners require.
What happens in the free 30-minute review?
You tell us what's breaking, we look at it with you, and we tell you what we'd fix first and roughly what it would involve. There's no cost and no obligation.
What is the difference between an EDI 940 and a 945?
They are a pair. The 940 is the warehouse shipping order: the customer tells the 3PL what to pick, pack, and ship. The 945 is the warehouse shipping advice: the 3PL reports back what actually shipped, including quantities, carrier, and tracking. If a 940 comes in and no 945 goes back, something stopped between the two, often an order hold, a mapping problem, or a confirmation tied to the wrong warehouse event.
What is the difference between a 945 and an 856?
A 945 goes from the 3PL back to its customer to confirm a shipment. An 856, the advance ship notice or ASN, goes to the retailer receiving the goods and describes what is on the truck, down to cartons and labels. In many setups the customer builds the 856 from the 945, so a late or wrong 945 can turn into a late or wrong ASN.
Why would a retailer reject an 856 ASN?
The usual causes are an ASN sent after the truck arrives, carton label numbers (SSCC) that don't match the ASN, quantities that don't add up through the hierarchy, a wrong PO or ship-to number, or missing carrier and weight details. Check the 997 first to see whether the file was rejected for its structure, then any 824 or retailer report for business-rule errors.
Do you work with Extensiv (3PL Central) and other WMS platforms?
Yes. We work with the WMS and EDI provider you already use, including Extensiv 3PL Warehouse Manager, and help connect warehouse events like receipts and shipments to the right outbound documents. We're based in New Jersey and work with 3PLs anywhere in the US.
