B2B fulfillment operates differently than D2C e-commerce. Instead of shipping single items to consumers, you're shipping cases and pallets to retailers, distributors, and other businesses. The volumes are higher, the requirements are stricter, and the penalties for non-compliance are immediate.
At 3PLGuys, we handle B2B fulfillment for brands selling to retailers from big-box chains to independent stores. EDI integration, pallet building, compliance labeling, and the routing guide expertise that keeps your retailer relationships healthy. Same-day processing for orders before 2 PM PT.
This guide covers how B2B fulfillment works and what to look for in a wholesale 3PL.
B2B vs. D2C Fulfillment
| Aspect | D2C Fulfillment | B2B Fulfillment |
|---|
| Order size | 1-5 items typical | Cases, pallets |
| Recipient | End consumer | Retailer, distributor |
| Order frequency | Many small orders | Fewer large orders |
| Shipping | Parcel carriers | LTL, truckload |
| Requirements | Basic | Routing guides, compliance |
| Penalties | Returns, complaints | Chargebacks, fines |
| Documentation | Invoice, tracking | ASN, BOL, packing list |
Many brands do both — D2C through their website and B2B through retail channels. Your fulfillment partner must handle both models.
Types of B2B Orders
Retailer Purchase Orders
Retailers send purchase orders specifying exactly what they want, when, and how it should arrive.
| Element | Description |
|---|
| PO number | Retailer's order identifier |
| Ship-to location | Specific distribution center |
| Items and quantities | SKUs and case counts |
| Ship date | When order must leave |
| Cancel date | Order expires if not shipped by |
| Routing instructions | How to ship |
Distributor Orders
Distributors aggregate products for resale to smaller retailers.
| Difference from Retail | Implication |
|---|
| Less rigid requirements | More flexibility in shipping |
| Relationship-based | Service quality matters |
| Reorder patterns | Predictable, recurring orders |
| Credit terms | Payment timing varies |
Wholesale Direct Orders
Small retailers, boutiques, or other businesses order directly from your brand.
| Characteristic | Handling |
|---|
| Smaller quantities | May ship parcel or LTL |
| Less formalized | Order via phone, email, portal |
| Varied requirements | Case by case |
| Payment | Often prepay or credit card |
EDI for B2B Fulfillment
Electronic Data Interchange (EDI) is standard for major retailer relationships.
Common EDI Documents
| Document | Code | Purpose |
|---|
| Purchase Order | 850 | Retailer sends order |
| PO Acknowledgment | 855 | You confirm receipt |
| Advance Ship Notice | 856 | You notify shipment details |
| Invoice | 810 | You bill retailer |
| Functional Acknowledgment | 997 | System confirms receipt |
EDI Workflow
- Retailer sends 850 — PO appears in your system
- You respond with 855 — Acknowledge order, confirm availability
- Fulfillment processes order — Pick, pack, label per requirements
- You send 856 (ASN) — Detailed shipment information
- Shipment delivers — Retailer receives and verifies
- You send 810 (Invoice) — Bill for shipped goods
EDI Integration Options
| Option | Description | Best For |
|---|
| SPS Commerce | Leading EDI network | Most brands; broad retailer coverage |
| TrueCommerce | Full-service EDI | Complex requirements |
| Direct connection | Point-to-point with retailer | Large volume, single retailer |
| 3PL integration | Through fulfillment partner | Simplified; 3PL handles EDI |
At 3PLGuys, we integrate with SPS Commerce to receive POs, generate ASNs, and manage EDI documents automatically.
Routing Guide Compliance
Every major retailer has a routing guide — detailed requirements for how shipments must be prepared and delivered.
Common Routing Guide Elements
| Element | Typical Requirements |
|---|
| Carrier | Collect freight vs. prepaid; approved carriers |
| Labeling | GS1-128, UCC-128, store-specific labels |
| Pallet specs | 48x40 GMA, stack height, wrap requirements |
| Carton specs | Weight limits, labeling positions |
| Appointments | Required scheduling, arrival windows |
| Documentation | BOL, packing list, PO copies |
Retailer-Specific Examples
| Retailer | Notable Requirements |
|---|
| Walmart | SQEP certification, specific ASN timing |
| Target | T+ dating, case label placement |
| Costco | Pallet display configuration |
| Amazon (vendor) | Specific carton labeling, appointment scheduling |
Each retailer has unique requirements. Your 3PL must know the details or learn quickly.
Compliance Costs
| Violation | Typical Penalty |
|---|
| Missing or wrong label | $50-150 per carton |
| Late shipment | Percentage of PO value |
| Wrong quantity | Full cost of overage/shortage |
| ASN errors | $100-300 per shipment |
| Pallet non-compliance | $50-100 per pallet |
| Missed appointment | $200-500 per occurrence |
Chargebacks erode margins fast. Compliance expertise is worth paying for.
Case and Pallet Fulfillment
B2B ships in bulk — cases and pallets, not individual items.
Case Picking
| Method | Use Case |
|---|
| Full case picks | Order requires complete cases |
| Inner pack picks | Order requires partial case (if allowed) |
| Mixed case building | Multiple SKUs per case |
Pallet Building
| Element | Specification |
|---|
| Pallet type | GMA 48x40 wood standard |
| Pallet grade | A or B quality |
| Stack configuration | Ti x Hi (cases per layer x layers) |
| Maximum height | Usually 48-60" product height |
| Stretch wrap | Clear, 3+ wraps top and bottom |
| Corner boards | Often required for stability |
| Pallet labels | Four sides, matching content |
Weight and Dimension Limits
| Limit | Typical Standard |
|---|
| Pallet weight | 2,000-2,500 lbs maximum |
| Pallet height | 48-60" product + 6" pallet |
| Carton weight | 40-50 lbs maximum |
| Stackability | Floor-loaded vs. stackable |
LTL and Truckload Shipping
B2B shipments often require freight shipping rather than parcel.
Shipping Mode Selection
| Mode | When to Use |
|---|
| Parcel | 1-10 cartons, under 150 lbs total |
| LTL | Pallets, over 150 lbs, under full truck |
| Truckload | Full trailer, 10+ pallets |
| Pool distribution | Multiple retailers, consolidated |
LTL Considerations
| Factor | Impact |
|---|
| Freight class | Determines pricing |
| Dimensional weight | Size vs. weight pricing |
| Accessorial charges | Lift gate, appointment, inside delivery |
| Transit time | Varies by lane, carrier |
| Claims | Damage/loss resolution |
Appointment Scheduling
| Requirement | Process |
|---|
| Lead time | Usually 48-72 hours advance |
| Window assignment | Specific arrival time range |
| Must-arrive-by | Missing window = rescheduling or rejection |
| Documentation | Appointment number on BOL |
Invoice and Payment Processing
B2B payment differs from D2C's instant payment.
Payment Terms
| Terms | Meaning | Cash Flow Impact |
|---|
| Net 30 | Pay within 30 days of invoice | Standard |
| Net 60 | Pay within 60 days | Common for large retailers |
| Net 90 | Pay within 90 days | Large retailers, long float |
| 2/10 Net 30 | 2% discount if paid in 10 days | Incentive for early payment |
Invoice Requirements
| Element | Purpose |
|---|
| PO number | Matches to retailer's order |
| Invoice number | Your reference |
| Line items | Products, quantities, prices |
| Ship date | When order left |
| Payment terms | When payment due |
| Remit-to address | Where to send payment |
Deduction Management
Retailers often take deductions from payments:
| Deduction Type | Cause |
|---|
| Compliance chargebacks | Routing guide violations |
| Shortage claims | Quantity discrepancies |
| Damage claims | Products arrived damaged |
| Pricing discrepancies | Price doesn't match agreement |
| Promotional allowances | Agreed marketing contributions |
Tracking and disputing invalid deductions is part of B2B operations.
Inventory Management for B2B
B2B inventory management has different considerations than D2C.
Safety Stock Calculation
| Factor | Consideration |
|---|
| Lead time | Retailer PO to ship date |
| Order variability | Promotional spikes |
