Shopify Wholesale Fulfillment: How Brands Grow Into B2B Without Breaking Their Operations

Shopify brands often start with D2C momentum. Orders are small, workflows are simple, and customer expectations are manageable. Then a wholesale opportunity appears. A specialty shop wants to carry the product. A regional chain places a test order. A major retailer shows interest. Suddenly fulfillment becomes more complex. Cartons must follow retailer rules. Orders must ship on pallets. Labels must follow strict placement guidelines. ASNs and EDI files must be perfect. At this point, Shopify wholesale fulfillment requires a 3PL built for B2B operations.

Many founders assume wholesale orders are just larger Shopify orders. They are not. Wholesale introduces compliance requirements that can overwhelm an unprepared warehouse. Incorrect labeling creates chargebacks. Wrong carton counts lead to rejected shipments. Inaccurate inventory causes delays. Connor Perkins, Director of Fulfillment, sees these struggles often. "One of the pain points our clients have experienced with previous 3PLs is inventory accuracy; maybe their previous 3PL wasn't great at picking the orders accurately. So they were losing money by shipping wrong items or wrong quantities of items." In wholesale, those mistakes create cascading financial consequences.

Why Shopify Brands Need Wholesale-Ready Fulfillment

Wholesale orders require a level of precision beyond what D2C demands. Retailers expect suppliers to follow detailed routing guides that outline how pallets are stacked, how cartons are labeled, and how ASNs must be transmitted. Failure to follow these rules results in chargebacks that quickly erase profit margins.

B2B Orders Require Strict Compliance

Retailers issue routing guides that dictate every detail of the shipment. Bryan Wright, CTO and COO, explains what is required. "They have routing guides that make you specific labels on and put them in a specific place on the box, and you have to send EDI, ASN, electronic information in a timely fashion. All of those kinds of things were built into our software from day one, and we have all of those capabilities for our customers." This is why Shopify brands expanding into wholesale need a 3PL with built-in retail compliance features.

A 3PL built only for D2C cannot execute the workflows needed for B2B shipments. That gap becomes expensive fast.

The Warehouse Management System Determines Wholesale Success

B2B fulfillment relies on a warehouse management system capable of tracking inventory by location, pallet, and carton. Without detailed tracking, wholesale shipments become error-prone. ASNs do not match physical shipments. Retailers issue penalties. Orders get rejected.

Inventory Accuracy Is Non-Negotiable

Bryan explains why system accuracy matters. "A bad WMS system will not track inventory 100 percent as it should. A good WMS tracks inventory through the warehouse at every point that you touch it." For wholesale, this traceability prevents mislabeled pallets and mismatched cartons.

System flexibility matters too. Bryan continues, "We can make that change extremely quickly because we have our own development staff. We have our own support staff. I know the software inside and out." Retailers update requirements often, and the 3PL must adapt quickly.

How Wholesale Fulfillment Fits Into Omnichannel Operations

Most Shopify brands expanding into wholesale also continue selling D2C and through marketplaces. This creates operational tension. A wholesale PO may require hundreds of units. Marketplace orders may spike on the same day. Without strong systems, one channel steals inventory from another.

Unified Inventory Prevents Channel Conflict

All orders must pull from the same accurate inventory. This is why Shopify wholesale fulfillment depends on real-time data. Joel Malmquist, VP of Customer Experience, describes how orders should flow. "There's a direct integration with Shopify where orders come in and flow directly into G10. We fulfill those, push back tracking to Shopify to show that the order hits, has been completed, which then fires an email out to the customer saying, your order's on the way." For wholesale, the fulfillment steps are more complex, but the inventory foundation remains the same.

When inventory accuracy is strong, wholesale becomes scalable instead of stressful.

Geography and Speed Influence Wholesale Performance

Retailers expect deliveries during exact appointment windows. Missing a delivery window can result in rejected shipments or large penalties. A multi-location fulfillment network improves delivery times and helps brands meet retailer deadlines.

A Distributed Network Supports Wholesale Growth

Holly Woods, Director of Operations, explains the advantage of G10's footprint. "We currently have locations in South Carolina, a couple in Wisconsin, Nevada, Arizona, and Texas. And we're always talking about new locations. This allows inbounds to come in faster, which means we can get it distributed faster." Faster inbound processing enables faster wholesale order prep.

When inventory is closer to retailers, shipping costs fall and delivery window accuracy increases.

Peak Season Tests Wholesale Fulfillment

Q4 brings massive demand across channels. Retailers issue large POs. Marketplaces surge. Shopify D2C orders spike. A wholesale-ready 3PL must scale without losing accuracy.

Agility Is Essential When Deadlines Are Non-Negotiable

Holly shares an example of the pressure wholesale shipments create. "We had inventory come in and it was delayed at the ports. Target has a deadline for delivery and that's it, no exceptions. Our team worked that entire day into the night, came back in the morning at 5 a.m. and got it ready." Wholesale fulfillment requires that level of execution every time.

Support Makes Wholesale Expansion Manageable

Wholesale creates new questions for founders: how to prep pallets, how to package cartons, how to read routing guides, how to avoid chargebacks. A wholesale-capable 3PL must provide clear, direct guidance.

Joel explains G10's support model. "If you're working with G10, your experience for getting help is that you can either email or call your direct point of contact. It's that simple." Quick access matters when working with retail partners.

Trust also matters. Jen Myers, Chief Marketing Officer, describes the emotional side of outsourcing. "If you're outsourcing your service and logistics you're putting the heartbeat of your company in the hands of someone else. I wouldn't do it unless I know who's on the other end, someone I can call and talk to, who I feel cares about my business almost as much as I do." Wholesale fulfillment requires that level of confidence.

When Shopify Brands Know They Need Wholesale Fulfillment

Most brands feel the pressure before recognizing the need. Retailers request detailed shipment requirements. Carton labels get rejected. Delivery windows get missed. Inventory becomes hard to track. Chargebacks appear. At this point, wholesale fulfillment becomes a priority.

Connor captures the decision point clearly. "As a growing business, the goal is to scale over time. Entrepreneurs need to look at their 3PL provider and say, can I scale with these guys and grow my business?" Wholesale requires a partner built for scale.

If your Shopify brand is stepping into wholesale or expanding retail relationships, now is the time to adopt wholesale-ready fulfillment. With the right systems and support, wholesale becomes a stable, profitable growth channel instead of an operational challenge.
