A Smarter Way to Order: Multiple Pack Sizes in a Single Order

Written by Harmonie Poirier | Nov 24, 2025 7:36:58 PM

Wholesale buying is seldom about “one SKU, one quantity.” Beverage distributors might order pallets and cases, retailers want six‑packs and singles, and manufacturers buy raw materials by weight and sell by piece. Traditional wholesale ordering systems force buyers to pick one unit of measurement per product per order. That meant unnatural workflows (creating duplicate orders for different pack sizes or leaving manual notes) and a lot of data cleanup.

 

OrderEase’s Mixed UoM Ordering

OrderEase lets buyers order any combination of pack sizes for a product in a single line item (3 × 12‑packs, 1 × 6‑pack, 4 singles, etc.). Suppliers define the relationships among units, e.g., 1 pallet = 12 cases, 1 case = 24 units, and buyers simply mix and match. No duplicate SKUs, no separate orders, no manual notes. This is especially useful for industries like beverage, CPG, lawn & garden, food, agriculture and manufacturing where mixed-case ordering is the norm.

 

Understanding UoM: Why It Matters

  • Supply‑chain alignment: Different stakeholders think in different units. Manufacturers produce pallets, distributors stock cases, retailers sell singles. Handling multiple UoMs within a single product ensures everyone speaks the same language and reduces costly misinterpretations.

  • Accurate costing and pricing: Being able to define special pricing per UoM lets suppliers encourage certain pack sizes while still offering singles for trial.

  • Inventory integrity: A robust UoM system prevents SKU duplication (e.g., creating separate SKUs for each pack size). Instead, packaging is metadata on the base item.

Without proper UoM handling in your ERP, companies end up manually converting quantities, creating parallel codes and adjusting inventory in two places. That’s error‑prone. OrderEase’s model centralizes the conversions so every unit change is automatically reflected across the system.

 

How This Sets OrderEase Apart From iPaaS and Traditional E‑Commerce

E‑Commerce Platforms: Built for B2C, Not B2B

B2C e‑commerce tools excel at straightforward transactions: one product, one price, one address. B2B orders, however, involve bulk quantities, multiple decision‑makers, negotiated pricing and custom delivery requirements.

B2B orders are larger and more complex, often tailored to specific customer needs, whereas B2C orders are simple and standardized. B2C platforms usually support simple “variants” (size/color) but not multiple pack sizes of the same product in one order. This limitation forces sellers to either create separate products for each pack size or rely on clunky add‑ons.

iPaaS: Great for Integration, Not Order Operations

Integration Platform as a Service (iPaaS) tools like MuleSoft or Boomi connect disparate systems (ERP, CRM, POS, etc.) but have no commerce domain knowledge. They don’t understand what an order is, how to split it into pick‑pack‑ship workflows, or how to reconcile pack sizes. in contrast, merchant‑friendly order hubs (like OrderEase) come with prebuilt commerce logic for orders, inventory, returns and routing.

OrderEase doesn’t just integrate systems; it manages orders end‑to‑end. It captures order details, validates pricing and inventory, routes orders based on complex rules, handles mixed UoM conversions and syncs data back into ERPs without custom coding.

For example, sellers complain that Amazon’s FBA can’t break a single pack to assemble a multi‑pack order; each bundle needs its own UPC, and many categories don’t allow quantity as a variation theme. The only workaround is to pre‑bundle products or create separate listings.

OrderEase solves these issues by making mixed‑UoM ordering a core feature rather than a hack.

 

Purpose‑Built B2B OMS Is The Solution

A modern B2B Order Management System (OMS) is more than a connector; it’s the nerve center of your operations. B2B order management systems manage order capture, validation, inventory, fulfillment, tracking and invoicing all in one place

An OMS is no longer a “nice-to-have” but a critical feature for B2B businesses, streamlining operations and reducing fulfillment errors by up to 35 %. It connects sales channels, automates manual tasks and ensures that orders move smoothly from purchase to delivery. For businesses handling thousands of orders per day, an OMS reduces manual data entry, improves workflow efficiency and boosts customer experience.

Key OMS Benefits for Mixed‑UoM Ordering

  • Unified Order Capture: Accept orders from portals, EDI, sales reps and e‑commerce sites, then normalize them into a single system.

  • Inventory Synchronization: Track inventory at the base unit and convert quantities across pack sizes automatically.

  • Workflow Automation: Route orders to the right warehouse or supplier based on product, pack size, location and priority.

  • Error Reduction: Automate pricing, discounting and promotions across different UoMs; avoid miscounting and misbilling.

 

Mixed‑UoM Ordering Unlocks True Wholesale Flexibility

Most B2C e‑commerce and integration platforms don’t treat mixed pack sizes as a first-class citizen. Sellers resort to duplicate listings, manual bundling or disconnected spreadsheets. Forum discussions show how frustrating this is. OrderEase’s mixed‑UoM ordering solves the problem by making pack sizes an intrinsic part of the product rather than an afterthought.

By building UoM conversion and management into a full‑fledged B2B OMS, OrderEase eliminates workarounds. Suppliers maintain one SKU with multiple pack options. Buyers order in the quantities that make sense for them. Inventory stays accurate. ERP integrations remain clean. Promotions are applied correctly across pack sizes. And because the logic is built for commerce, not just integration, there’s no need for custom coding when your business evolves.

If you’re ready to streamline wholesale ordering and support the way your customers actually buy, contact OrderEase for a demo. You’ll see how mixed‑UoM ordering and a purpose‑built OMS can transform your B2B operations.
