Wholesale and retail
B2B and Wholesale Office-Supplies Fulfillment, EDI and ASN Built In
Updated October 2026
Resellers, dealers and big-box retailers each set rules for how freight reaches them. Before a pallet leaves our dock, the ship notice, the labels and the pallet itself all have to match those rules.
To sell office supplies wholesale, each retailer expects three things. You send an EDI 856 advance ship notice that matches the freight. You label every carton and pallet to the GS1-128 standard. And the freight follows that retailer's routing guide. Retailers typically charge back for a miss on any of them. We handle all three, and we build pallets to spec.

Why wholesale is different
What changes when you sell to retailers
A direct-to-consumer order goes well if the right item reaches the customer undamaged. A retailer's purchase order is held to a routing guide, and the guide asks for more. The advance ship notice has to arrive ahead of the freight and match it. Every carton and pallet needs a correct GS1-128 label. The shipment has to arrive on time, packed and stacked the way the retailer asked.
When something is off, the retailer doesn't just complain. It typically deducts a chargeback from what it pays you. A warehouse that has only ever picked single units for consumers isn't a good fit for orders like these.
Retailer requirements
The four parts of retail compliance
Retailers typically check the ship notice, the labels and the routing guide on every shipment, and charge you back when one is missed. The details differ from one retailer to the next.
1. The EDI 856 advance ship notice (ASN)
The EDI 856 is an electronic notice sent ahead of the freight. It lists what is in the shipment and how it is packed, down to each carton and item, and the retailer's receiving dock scans the freight against it. A notice that is late, missing or wrong makes the shipment non-compliant the moment it arrives. We generate the ASN from the same pick that built the shipment, so the notice and the freight describe the same goods.
2. GS1-128 carton and pallet labels
GS1-128 is the barcode label standard for cartons and pallets shipped between businesses. Each label carries a serial shipping container code (SSCC), a number unique to that carton or pallet, plus the contents and routing data the retailer's system reads. The retailer also decides exactly where the label goes and what data it holds. A label that's wrong, missing or won't scan usually turns into a line on a chargeback. We print GS1-128 carton and pallet labels to each retailer's routing guide.
3. The retailer routing guide
Each retailer publishes a routing guide, its rule book for how freight must arrive. A guide covers points like these:
- which carrier to use
- delivery appointment windows
- pallet height and configuration
- carton markings
- the ASN and label details above
Guides differ from one retailer to the next, and retailers rarely bend them. We prep orders to the routing guide and build pallets to its spec. A reseller, dealer or corporate account gets freight set up the way it asked, rather than the way a warehouse would stack it by default.
4. Chargebacks, when something is missed
A chargeback is money the retailer deducts from your invoice when a shipment breaks its routing guide. Common causes include:
- a late or missing ASN
- a mislabeled carton
- a pallet built the wrong way
- a delivery that arrives early or late
- a count that doesn't match the ship notice
Chargebacks are how retailers pass the cost of a broken rule back to the vendor, and they eat into wholesale margin a little at a time. No warehouse can promise to end them. Careful picking and labeling can help keep them rare.
EDI maps
EDI maps are built around the retailers you sell into
Some 3PLs show a wall of retailer logos and imply a map for each one is already waiting. EDI maps aren't made that way. An EDI map translates between one retailer's document format and your order system, and every retailer's map, routing guide and label rules are a little different. We set up maps account by account during onboarding, for the retail and dealer channels you sell into. You send us your list of trading partners, and we build the maps from it.
The prep work stays the same from account to account. ASN generation, GS1-128 carton and pallet labels, routing-guide prep and pallet builds all run in BestOMS, with Deposco behind it. That is the same order system that picks and ships your direct and marketplace orders. Our B2B and retail fulfillment page has more on the prep.
Accuracy
A clean ASN starts at the pick
An advance ship notice helps only when it's accurate. Say the carton holds a different item than the ASN lists, or the count is an inner pack short. The notice that should have sped up receiving now flags a discrepancy, and a chargeback often follows. A label only reports what was picked, so getting compliance right mostly means picking the right units.
A wholesale order can call for inner packs, full cases or full pallets of the same SKU. Every pick is scanned before it goes into a carton bound for a retailer's dock. With the right units in the carton, the label and the ASN describe freight that should scan in cleanly. For more on picking, see breakpack and each-level picking. Recurring wholesale orders are covered in contract and subscription replenishment.
Wholesale orders also lean toward freight: a full pallet of paper, a dealer's furniture order, a machine rollout across a corporate office. We ship those by parcel, LTL or FTL, whichever suits the order, and pack them with dimensional weight in mind. Our warehouses reach 99.77% of the US in 1-3 day ground between them, so if you spread wholesale stock across several, a dealer's order can leave from whichever sits closest to its dock.
Choosing a 3PL
How to vet a 3PL for a wholesale office program
Put three questions to any warehouse you're considering:
- Can you produce the EDI 856 ASN and GS1-128 carton and pallet labels, and build pallets to a routing guide? Can you show me those tied to the actual pick?
- How do you set up EDI maps for the retailers I sell to, and how long does each one take? A specific answer tells you far more than a page of logos.
- How do you check picks? An ASN is only as accurate as the pick behind it.
Our answers: yes, straight from the pick that built the shipment; account by account, starting from your list; and a scan on every unit we pick. Every carton in a wholesale shipment holds product you or your supplier made. The office and school supplies arrive finished and sealed, and as a 3PL we don't manufacture, refill or remanufacture any of it.
Questions about wholesale office-supplies fulfillment
What does B2B and wholesale office-supplies fulfillment require?
Resellers, dealers, big-box retailers and corporate buyers each expect three things from a wholesale shipment. The EDI 856 advance ship notice (ASN) has to match what is physically in the shipment. Cartons and pallets need GS1-128 labels carrying the right SSCC and contents data. The freight has to follow that buyer's routing guide. Get any of them wrong and the retailer will typically charge you back. We handle all three, and we build pallets to each buyer's spec. Your retailer connections are set up when you onboard, around the accounts you actually sell to. Tell us who you ship to and we'll go through what each one requires.
Do you support EDI 856 ASN and GS1-128 labeling?
Yes. The ASN tells a retailer what's coming and how it's packed. The GS1-128 label carries the SSCC and contents data the receiving dock scans to check in each carton and pallet. Between them they cover most of what retail compliance asks for. We produce both, prep each order to the routing guide and build pallets to spec. Your connections are built at onboarding, around the retailers you sell to, so bring us the accounts that matter and we'll take it from there.
Will you keep me out of retailer chargebacks?
No warehouse can promise that. A chargeback is a retailer billing you back when a shipment breaks its rules: a late or missing ASN, a mislabeled carton, a pallet built the wrong way, or a count that doesn't match the ship notice. What keeps that exposure down is careful daily work. We scan every pick so the carton matches the ASN, print GS1-128 labels to the routing guide and build pallets to spec. Each trading partner's routing-guide rules and EDI map are set up at onboarding, so the prep matches what that partner checks.
Which retailer EDI maps do you operate?
We build them during onboarding, for the retailers and dealers you actually sell to, because each one has its own map, routing guide and label rules. Send us your list of accounts and we'll go through each one with you. The prep itself doesn't change from one account to the next: the EDI 856 ASN, GS1-128 carton and pallet labels, routing-guide prep and pallet builds, all run on the same system that picks and ships your direct and marketplace orders.
Can the same inventory ship to retailers, dealers, and direct-to-consumer?
Yes, from one pool of stock. We track inventory by the single unit, the inner pack, the case and the pallet, so the same SKU can go out as a few inner packs to a small dealer, a full pallet with an ASN and GS1-128 labels to a retailer, and a single unit to a consumer. Every channel feeds into BestOMS, so a unit sells only once across wholesale EDI, marketplace and direct orders. Each order is scanned as it's picked and can ship from the warehouse nearest where it's going.
How do you keep accuracy on wholesale pallet orders?
A wholesale order is judged on whether each carton matches the ASN and each pallet matches the routing guide. We scan picks at the unit and case level, which is there to catch the office mix-ups that are easy to make, such as the wrong toner model, pen color or paper weight, before they reach a pallet. Cartons are labeled to the routing guide and pallets are built to spec. That way what the retailer scans in can match what the ASN said was coming.
