Wholesale Demand Planning That Stops Inventory Panic

Wholesale demand planning often feels like predicting the weather: everyone wants certainty, nobody gets it, and retail buyers change their minds faster than a Midwestern forecast. Search trends show operators asking why is my wholesale forecast always wrong or how do I stop inventory shortages, usually after a retailer submits a surprise PO or cancels one without warning.

If you have ever felt like your demand plan was built on optimism instead of data, you know how fragile wholesale forecasting can be.

Why wholesale demand planning is so difficult

Wholesale demand is lumpy, uneven, and tied to decisions brands cannot control. Retailers place orders in bursts. Distributors reorder unpredictably. Inbound manufacturing cycles shift with delays, supplier hiccups, or freight constraints. The result is a planning puzzle that is never solved the same way twice.

Joel Malmquist, VP of Customer Experience at G10, sees the consequences firsthand. "If you do not do it right, you get those massive chargebacks." Poor planning spills into poor performance.

Where wholesale demand planning usually fails

Most failures begin with inaccurate warehouse data. If inventory counts are wrong, any forecast built on that foundation collapses immediately. Many brands discover this too late, after a retailer questions a short shipment or rejects a partial delivery.

Connor Perkins, Director of Fulfillment, explained the pattern. "One of the pain points our clients have experienced with previous 3PLs is inventory accuracy. Maybe their previous 3PL was not great at picking the orders accurately. So they were losing money by shipping wrong items or wrong quantities of items." Without accurate inventory, demand planning is guesswork.

Why D2C-first systems break wholesale planning

D2C demand is fairly predictable. It follows seasons, ads, promotions, and customer patterns. Wholesale demand does not. Retailers may order large quantities without warning. They may pull back suddenly. They may expedite delivery windows. D2C-first systems cannot support the planning complexity required to maintain wholesale service levels.

Bryan Wright, CTO and COO, highlighted the root issue. "A bad WMS will not track inventory 100 percent. A good WMS tracks inventory through the warehouse at every point you touch it." Demand planning needs that visibility to function.

The communication breakdown that wrecks forecasting

Many 3PLs treat forecasting questions as low priority. They route them through ticket queues, where responses take days. Brands ask when stock will arrive, whether inventory is adequate, or if purchase orders should be staggered. Meanwhile, retailers expect commitments quickly.

Joel described the contrast. "At some 3PLs you get thrown into a ticketed queue, and you get different people replying every time. It can take days, if not weeks, to get a resolution." Forecasts fall apart when answers arrive late.

At G10, forecasting questions get immediate attention. "You call one person. That is it. And things get done," Joel said.

What strong wholesale demand planning looks like

A healthy wholesale demand process has three pillars: accurate data, structured forecasting cycles, and operational readiness. Inventory must be accurate. Inbound timelines must be clear. Retailer patterns must be studied, not assumed. Purchase orders must be aligned with supply lead times, not stacked arbitrarily.

Connor explained why planning begins in onboarding. "When we onboard a client who sells into places like Amazon or Walmart, the process changes depending on where they are selling. We work through all of their routing guide requirements and make sure the warehouse is ready before the first order ever drops." Planning is proactive, not reactive.

How demand planning holds during high-pressure seasons

The true test of wholesale planning comes during peaks: holiday surges, retailer resets, early reorders, and promotional spikes. Weak planning buckles. Strong planning flexes.

Joel shared a moment when a Target-bound order arrived at the ports late. "Our supervisor, warehouse manager, and several employees worked the entire day into the night, then came back at 5 a.m. to make sure we had the routing completed." Good planning made fast execution possible.

Another moment came during a viral spike. "The client asked, Can you help us? And we said, Yeah, we gotcha. Then we sent a truck to the carrier at midnight." Planning and execution stayed aligned even through the chaos.

The bottom line for wholesale brands

Wholesale demand planning is not prediction. It is preparation. It depends on reliable data, responsive communication, and a warehouse that builds workflows around retail realities. When planning works, retailers see a steady, dependable supply chain. When it fails, they see inconsistency and risk.

If you want demand planning that protects your inventory, your margins, and your retailer relationships, reach out to G10. You will get forecasting support that adapts to the real world instead of wishing it were simpler.
