Why brands are switching now

Fashion inventory has never been this complex — or this costly to get wrong

Industry days inventory outstanding hit a record 168 days in 2024 (McKinsey State of Fashion 2026). US apparel tariffs swung from 13% to 54% to 36% within twelve months. TikTok Shop overtook Target in apparel GMV for the first time. And 78% of fashion executives now rank consumer confidence as their top growth risk. The brands adapting fastest aren’t buying more stock — they’re buying smarter, at the variant level. For brands balancing a fashion ecommerce platform, marketplaces, POS data, clothing fulfillment partners, and apparel ERP records, planning has to be just as connected as the sales model.

Analytics report

Merchandising & Sell-Through Analytics:

See which colors and styles are selling — and which are draining margin. Option-level insights show sell-through by color, size, and style at each discount tier. Range plans stop repeating last season’s mistakes.

Supply chain

Multi-Location Inventory Tracking:

One stock view across every warehouse, store, and marketplace. Unified allocation logic across Shopify, Amazon, eBay, Walmart, brick-and-mortar, and 3PL nodes. Hot SKUs stop going out of stock in one channel while sitting idle in another.

Truck icon representing faster replenishment

Shelf & Shipping Optimization:

Cut the stock sitting on Amazon’s shelves for 365 days. Transfer order recommendations move inventory to where demand is highest — so FBA stock turns fast instead of tying up working capital for months.

Suppliers

Supplier Management:

Know which suppliers are costing you margin before you commit. Track lead times, fill rates, and supplier performance natively. Factor actual lead time into every replenishment recommendation — critical when Asia sourcing runs 60–120 days.

Built for fashion. Not retrofitted for it.

Your ERP tracks inventory. Inventory Planner tells you what to buy next.

Most inventory management systems were built for generic retail. They track stock levels. They process purchase orders. But they weren't designed for variant-level fashion complexity: cut, size, and color combinations that multiply your SKU count by 10x; new styles with no sales history; seasonal trend cycles that shift demand in weeks; or open-to-buy budgets that need to align to gross profit, not just units. Inventory Planner was.

Your ERP / IMS

Tracks what you have

Tracks inventory. Processes orders. But wasn't built to forecast by variant, plan open-to-buy by season, or account for fashion trend cycles — those gaps are where brands lose margin.

Spreadsheets

Can't scale to 10K+ SKUs

At 10,000+ SKUs across sizes and colors, Excel becomes the bottleneck. Manual replenishment takes weeks. Errors compound. Stockouts cost revenue that spreadsheets can't prevent.

Inventory Planner

Tells you what to buy next

Variant-level demand forecasting. Automated PO creation. Open-to-buy planning. Option-level sell-through analytics. 30+ native connectors. Works alongside your ERP, not instead of it.

"Even if you have an inventory management system, you still need Inventory Planner. Your IMS tracks what you have. Inventory Planner tells you what to buy next and how much."

Easy integrations

Connects to everything your fashion brand runs on

Fashion brands don't run on one platform. You're on a fashion ecommerce platform like Shopify plus Amazon FBA plus a 3PL for clothing fulfillment plus/or an ERP — and you need one planning tool that sees all of it. Inventory Planner connects natively to 30+ platforms across ecommerce, marketplaces, warehouse management, and ERP, so your demand forecasts and buying recommendations reflect your real, multi-channel demand. No CSV exports. No manual reconciliation.

Frequently asked questions

What is inventory planning for fashion brands?

Inventory planning for fashion brands is the process of forecasting demand at the variant level — by size and color— setting open-to-buy budgets by season and generating purchase orders and replenishment recommendations across every sales channel. Unlike standard clothing store inventory software or generic retail inventory management, fashion inventory planning must account for trend cycles, new style buying with no sales history, and stock allocation across Shopify, Amazon, brick-and-mortar, and wholesale simultaneously.

How is Inventory Planner different from an ERP or apparel inventory management software?

An ERP or fashion inventory management system tracks what stock you have and processes orders. Inventory Planner tells you what to buy next, how much, and when — at the variant level. It works alongside your ERP (NetSuite, Cin7, Brightpearl, Acumatica, and more), pulling sell-through data and pushing purchase orders, so your planning layer handles the fashion complexity your ERP wasn’t built for.

Can Inventory Planner handle multi-channel fashion brands?

Yes. Inventory Planner connects natively to 30+ platforms including Shopify, Amazon, eBay, Walmart, Square, BigCommerce, and Adobe Commerce, plus 3PLs like ShipBob, ShipHero, and ShipStation. It aggregates demand across every channel into one forecasting view, so stock allocation decisions reflect your real multi-channel demand.

How does Inventory Planner forecast demand for new styles with no sales history?

Inventory Planner borrows sales data from comparable existing styles to build opening-order recommendations for new SKUs. Buyers can configure which reference styles to use and adjust the model by category, season, or channel — so new style buys are informed by actual performance data, not gut feel.

What is open-to-buy (OTB) planning, and does Inventory Planner support it?

Open-to-buy (OTB) is the budget a fashion buyer has available to purchase new inventory in a given period, after accounting for existing stock commitments. Inventory Planner’s OTB module aligns buying recommendations to your OTB budget by category, season, or supplier — so commitments stay within plan and carry-over stock doesn’t crowd out next season’s buys.

How does Inventory Planner help with aged stock?

Inventory Planner’s aged-stock alerts flag SKUs at risk of becoming non-replenishable before they reach mandatory markdown or write-off. Sharp Attire flagged 5,000 SKUs as non-replenishable within three months of onboarding, reclaiming ~$430K in profit.

Is Inventory Planner right for Shopify fashion brands under $50M GMV?

Yes — Inventory Planner is specifically built for fashion brands at $5M–$100M GMV on Shopify or Shopify Plus. Onboarding is designed for brands that have outgrown inventory spreadsheets but aren’t ready for a six-figure enterprise ERP implementation. Sparkle In Pink, Freedom Rave Wear, Caden Lane, and MaxColor are all in this range.

How long does implementation take?

Most Shopify-native fashion brands are up and running within days, not months. Inventory Planner installs directly from the Shopify App Store and connects to your existing sales channels, ERP or IMS via native connectors to create a cohesive fashion ecommerce platform for your brand. No custom development is required.

Does Inventory Planner connect with other fashion ecommerce software?

Yes. Inventory Planner connects with fashion ecommerce platforms and marketplaces including Shopify, Shopify Plus, BigCommerce, Adobe Commerce, Amazon, eBay, Walmart, and more. It brings sales and demand data into one planning view, so buying recommendations reflect performance across every channel.

Can stores using POS systems use Inventory Planner?

Yes. Clothing stores using a clothing POS system can use Inventory Planner to combine store sales, ecommerce data, marketplace performance, and warehouse inventory into one forecasting view. This helps buyers plan replenishment based on real demand instead of disconnected retail and online reports.

How does Inventory Planner fit into a fashion supply chain software stack?

Inventory Planner complements your fashion supply chain software by turning sales, supplier, inventory, and fulfillment data into planning recommendations. Instead of only tracking supply chain activity, it helps teams decide what to reorder, where to place stock, when to buy, and how to protect margin across channels.

Is Inventory Planner clothing store inventory software?

Yes. Inventory Planner works as clothing store inventory software for fashion and apparel brands that need to plan stock across retail locations, ecommerce channels, marketplaces, and warehouses. But it goes beyond basic store inventory tracking by helping teams forecast demand, plan replenishment, manage open-to-buy budgets, and decide what to buy next by size, color, style, channel, and location.
