Keep one accurate stock position across Shopify DTC, wholesale, and marketplaces, so the same unit is never promised twice.
Shopify is built to track inventory for direct-to-consumer storefronts, and it does that well. The problem starts when the same stock has to serve wholesale buyers, B2B pre-orders, and marketplaces at the same time. Those commitments live outside Shopify, so the brand ends up reconciling availability by hand.
The cost shows up at peak. A wholesale allocation and a DTC checkout draw down the same physical units, but neither system knows what the other promised, so the brand oversells, scrambles to fulfill, and explains the shortfall to a retail buyer.
Shopify wholesale inventory sync is the problem of keeping one accurate stock position across Shopify DTC, wholesale and B2B orders, and any marketplaces, so the same unit is never sold twice. Shopify tracks DTC stock well, but wholesale pre-orders, allocations, and partner shipments live outside it, so brands reconcile by hand and oversell at peak. Uphance holds one inventory pool across Shopify DTC, the B2B portal, and marketplaces, reserves wholesale pre-orders against production, and syncs in real time so a wholesale commitment and a DTC sale draw from the same stock.
For an apparel brand running Shopify DTC alongside a wholesale book, inventory is the seam that breaks first. Shopify holds the DTC stock position. Wholesale orders, pre-orders, and allocations are tracked somewhere else, often a spreadsheet, sometimes a separate B2B tool. A sync app can push a single available number into Shopify, but it cannot reason about what wholesale has already committed against production that has not landed yet.
This is breakpoint three of the 6 Breakpoints framework, inventory truth, compounded by breakpoint four, order flow. When the wholesale and DTC channels do not share one live inventory pool, the brand cannot trust any single availability number. Teams add manual holds, pad buffer stock, and stop selling the last units of fast movers to avoid the oversell, which leaves real demand on the table.
Uphance closes the seam by holding one inventory pool that Shopify DTC, the B2B portal, and marketplaces all draw from in real time. Wholesale pre-orders reserve against production and incoming stock, so available-to-promise reflects what can actually ship. A DTC sale and a wholesale allocation cannot both claim the same unit, because there is one record, not two systems guessing.
One live stock position across Shopify DTC, wholesale, marketplaces, and every warehouse or 3PL location.
DTC, wholesale, and marketplace orders allocated against the same inventory pool, with no double-promising.
Wholesale ordering with live availability, pre-orders, and allocations that reserve against real stock and production.
Real-time inventory sync with Shopify so the DTC storefront reflects the one true stock position.
Incoming production and stock dates feed available-to-promise, so pre-order commitments are grounded.
Amazon, Mirakl, and Rithum/DSCO draw from the same pool, so a third channel does not reintroduce oversells.
If your brand runs Shopify DTC and wholesale from stock that two systems track separately, the oversells and the manual reconciliation are not a discipline problem, they are an architecture problem.
