Multichannel Inventory Management

Inventory becomes chaotic when each channel tracks its own truth

Most brands discover the pain of multichannel inventory the hard way. Shopify says one thing, Amazon says another, Walmart has its own numbers, and retail partners expect perfect accuracy regardless of what your systems claim. At some point the team realizes the problem is not demand. The problem is drift. Every channel acts like it owns the inventory, and none of them agree. That is where multichannel inventory management becomes essential instead of optional.

Search patterns show this stress rising across the industry. People look up terms like fix my multichannel inventory, why channel counts do not match, and unify Shopify and Amazon stock. They are looking for one simple thing: a single version of the truth.

Disconnected channels cause predictable mistakes

When each platform uses its own inventory logic, conflict follows. A large retailer PO might consume stock the D2C channel needed. Shopify may let orders through because Amazon has not synced yet. Amazon may oversell because the system believes stock exists in a location that already shipped product to a retailer. None of these failures are accidental. They all come from the same issue: fragmented stock control.

Maureen Milligan captured this pattern clearly. She said, "Most of the customers who come to us from another 3PL, their challenges have always been access to their data, order accuracy and efficiency, and basically just meeting the committed requirements." Those failures always trace back to poor inventory alignment across channels.

Multichannel inventory starts with one source of truth

Multichannel inventory management begins by pulling every channel into a single shared inventory pool. That means Shopify, Amazon, marketplaces, and retailers all reference the same stock count in real time. When that happens, overselling slows down, backorders shrink, and the brand finally sees what is truly available.

Connor Perkins highlighted why this matters. He said, "Our clients get best-in-class visibility and transparency. They can see their daily orders, they can see KPIs, and they can see historical transactions." That clarity only exists when every channel draws from unified inventory.

The WMS is the anchor for multichannel accuracy

A warehouse management system holds everything together. It must record every movement precisely so that all channels have clean data to work with. Bryan Wright put it plainly. "A bad WMS system will not track inventory 100 percent as it should." Without perfect visibility inside the warehouse, multichannel inventory collapses instantly.

Bryan also explained how G10's WMS was designed around B2B and expanded into D2C. "If they have a Walmart account, we can create the Walmart-specific label," he said. That depth of configuration keeps every channel consistent, even when the requirements differ dramatically.

Robots strengthen inventory accuracy through consistent movement

Physical workflows matter just as much as digital systems. Holly Woods described how Zebra robots improve consistency inside the warehouse by guiding carts along optimized routes. "The robot is round, it looks like an industrial Roomba," she said. Because the robots reduce unnecessary movement, inventory stays accurate, which keeps all channels synchronized.

D2C, B2B, FBA, and marketplaces share the same stock pool

One of the hardest parts of multichannel sales is balancing the demands of different order types. D2C wants speed. Retailers want precision. Amazon wants cartons prepared exactly their way. Marketplaces want immediate availability. Multichannel inventory management solves this by letting every order pull from the same real-time numbers.

Joel Malmquist described how orders flow through the operation. "We are the ones shipping the orders for these brands," he said, explaining how tracking and confirmations route back into Shopify and retailer portals. That accuracy only works when inventory stays unified.

Surges do not break a unified inventory engine

Multichannel inventory management matters most during spikes. When a promotion hits, or Amazon surges, or a retailer demands extra pallets with almost no warning, disconnected systems collapse. Unified inventory systems stay steady because they see everything at once.

Joel shared an example of this. A merchant asked whether G10 could fulfill ten Target POs in forty-eight hours. Joel answered, "Yes we can," because multichannel inventory stayed synchronized across all facilities. There was no guessing about where stock lived.

Customer service improves instantly when inventory aligns

Most customer service issues start with incorrect inventory. Wrong counts lead to late shipments, cancellations, and apologies nobody wants to write. When inventory becomes unified, support teams can finally give answers quickly and confidently. Joel emphasized this when he said, "Every single account at G10 has a direct point of contact." That person can solve problems because they trust the data.

Multichannel alignment supports expansion

Brands expand into new channels more easily when inventory is unified. New marketplaces do not introduce chaos. New retailers do not create shortages. Jen Myers explained why alignment matters. She said, "You want to make sure your inventory is tracked across those two different systems," especially when Amazon wants pallets and D2C customers order at the same time.

Unified inventory removes the fear of launching new channels.

A system built for builders

Founders need systems that grow with their ambition. Mark Becker summarized the mindset behind G10's approach. He said, "At the end of the day, all we are is builders. The two of us love to build." Multichannel inventory management supports that mindset by giving brands room to scale without losing control.

The future belongs to brands with unified multichannel inventory

Multichannel inventory management is more than a tool. It is a foundation. When every channel pulls from the same accurate numbers, brands ship faster, scale smarter, and avoid preventable mistakes. If your inventory feels inconsistent, reactive, or difficult to trust, unifying it can solve the problem at the root.

With one source of truth, your team stops guessing and starts growing.
