Join the Linnworks and Shopify sellers who've already made the switch to smarter, faster, better inventory planning.

Ready to See the Difference?

Replenagise was born in 2026 from two simple frustrations: Linnworks sellers deserved better inventory planning, and Shopify sellers were tired of juggling multiple stores with no real control. Better channel intelligence. Better multi-store management. Better speed. So a leading e-commerce industry expert built exactly that — for both.

Most platforms take months to ship a feature request. We take days. We listen to what our customers need, we build at speed, and we deploy fast. Our roadmap isn't a wish list collecting dust — it's a live pipeline that moves at the pace our users demand.

We aren't scared to explore. We aren't scared to break new ground. If a feature will make your life easier, we'll find a way to build it — and we'll do it before anyone else.

We Listen. We Build. We Ship.

Every inventory planning system out there was doing some of the job — but none of them were doing all of it. For Linnworks sellers, channels were synced as warehouses, not as actual channels. You couldn't see which locations were linked to which channels, compare what needed transferring vs what didn't, or raise POs instantly. For Shopify sellers, running more than one store meant juggling stock across them with no single view, no easy way to move inventory between them, and no way to automate the busywork. You certainly couldn't see what needed moving from warehouse to FBA, which store or channel was overstocked, or compare Channel A vs Channel B year on year.

Replenagise changed all of that. Now you can raise transfers straight into Shopify, automate those transfers, and automate your purchase orders — across both Linnworks and Shopify. Built by someone who lived and breathed e-commerce operations, this platform was designed from the trenches — not from a boardroom. Every feature exists because a real Linnworks or Shopify seller needed it.

Planning Depth, Multichannel Breadth

Cogsy Alternative — FAQs

Cogsy is demand planning built for single-store DTC brands on Shopify and Amazon, priced at $199/month. Replenagise delivers the same planning jobs — demand forecasting, replenishment alerts, automated purchase orders — across multiple Shopify stores and every channel connected to Linnworks, with pricing built for growing sellers.

Cogsy launched in 2020, founded by WooCommerce co-founder Adii Pienaar and backed by a $5M Accel-led seed round. It built a loyal following among direct-to-consumer brands with demand forecasts up to 12 months out, replenishment alerts, purchase orders, backorder and pre-order workflows, and “growth plans” that tie inventory decisions to cash flow. It connects to a Shopify store, Amazon, and a set of 3PL and inventory systems such as ShipBob, ShipHero and Cin7 Omni, on a single all-in-one plan at $199/month (as of July 2026).

That is a strong toolkit for a single-brand DTC operation. But Cogsy is built around one Shopify store plus Amazon: there is no native eBay or other marketplace integration, and no support for running multiple Shopify stores in one account — its “multi-location” features cover the warehouses behind one store, not several storefronts. Replenagise was built for the sellers on the other side of that line: demand forecasting on every SKU across every store and channel, automated purchase orders and stock transfers, connected directly to Shopify and Linnworks.

What Cogsy does — and where it stops fitting

Cogsy deserves credit: it brought genuinely fresh thinking to DTC inventory planning, and its Shopify App Store listing still holds a 4.9-star rating. If you run one Shopify store plus Amazon, plan purchasing around cash flow, and lean on pre-orders and backorders, Cogsy remains a credible option for your shortlist.

Two things belong in any 2026 evaluation, though. First, fit: Cogsy is deliberately DTC-shaped — one store, one brand — and no amount of configuration adds eBay, other marketplaces or additional Shopify stores. Second, momentum: Cogsy was reportedly acquired in 2023, founder Adii Pienaar has since moved on, and the newest of its 13 public App Store reviews dates to mid-2023 — so it is worth asking about the current team and roadmap in a demo before you commit.

Replenagise is the multichannel equivalent of the planning depth Cogsy offers: forecasts on every SKU across every store and channel, safety stock and reorder points, and purchase orders and transfers raised automatically in Shopify and Linnworks — priced for growing sellers rather than funded DTC brands.

1. Every channel, not just Shopify + Amazon

2. Multiple Shopify stores, one plan

Best Shopify Inventory Management — FAQs

Looking for the best inventory management software for Shopify? We ranked the top Shopify inventory apps for 2026 on demand forecasting, automated purchase orders, multi-store support and value. Replenagise comes out on top, with strong options from Inventory Planner, Cogsy, Prediko and Shopify’s own tools.

Shopify is brilliant at selling — but on its own it only tells you what stock you have right now. It will not forecast what you are about to sell, tell you when to reorder, or move stock between your stores and locations. That gap is exactly what a dedicated Shopify inventory management app fills.

When you compare the best inventory management software for Shopify, five things matter most: accurate demand forecasting, automated purchase orders, multi-store and multi-location support, real-time API sync (no CSV exports), and price. The right pick depends on your size and how many stores and channels you run — so below we rank the leading Shopify inventory apps for 2026 and explain who each one is best for.

How to choose the best Shopify inventory management app

We assessed each app on the jobs Shopify itself does not do: demand forecasting accuracy, automated purchase orders, multi-store and multi-location transfers, real-time API sync, and value for money. Apps that only sync or mirror stock levels scored lower than those that actually forecast demand and tell you what to order and move.

Replenagise ranks first because it covers all five — forecasting, automation, multi-store transfers, live sync and affordable pricing — in a single platform, and backs it with the same engine trusted by Linnworks sellers. Your own shortlist should still start with your store count, channel mix and budget.

How we ranked these Shopify inventory apps

The 6 best Shopify inventory management apps in 2026

1. Replenagise — Best overall

2. Inventory Planner by Sage — Best for established brands

5. Stocky by Shopify — Being retired in 2026

6. Shopify’s built-in inventory tools — Best free baseline

Enterprise-Grade Planning, Minus the Enterprise

Slimstock Alternative — FAQs

Slimstock’s Slim4 platform is enterprise supply chain planning built for ERP-driven wholesalers, distributors and manufacturers. Replenagise delivers the planning jobs you would buy Slim4 for — demand forecasting, safety stock, automated replenishment — connected directly to Shopify and Linnworks, live in minutes with transparent pricing.

Slimstock is one of Europe’s best-known supply chain planning companies, founded in the Netherlands in 1993. Its platform, Slim4, covers demand forecasting, inventory optimisation and sales & operations planning (S&OP) for wholesalers, distributors, manufacturers and large retailers — typically integrated with an ERP such as NetSuite, SAP or Sage, and rolled out as a consultant-supported implementation project.

That is exactly right for an enterprise supply chain team. But if you sell on Shopify, Amazon or eBay and run your operations through Shopify or Linnworks, an ERP-first enterprise platform brings cost, complexity and a sales cycle you do not need. Replenagise was built for that gap: the same core replenishment intelligence — demand forecasting on every SKU, reorder points and safety stock, supplier lead times, automated purchase orders — connected directly to your ecommerce platform via API.

What Slimstock does — and where it stops fitting

Slimstock has three decades of supply chain heritage, and Slim4 is a capable platform in the world it was built for: ERP-driven wholesale, distribution and manufacturing, with dedicated planning teams who live in S&OP cycles. If that describes your operation, Slimstock deserves a place on your shortlist.

Replenagise is the equivalent intelligence for ecommerce operators. It assumes your stack is Shopify or Linnworks rather than an ERP, prices for growing sellers rather than enterprises, and closes the loop from forecast to purchase order automatically. If your business runs on an ecommerce platform, you should not have to buy — and implement — an enterprise supply chain suite to get world-class replenishment.

Slimstock vs Replenagise: an honest comparison

Why ecommerce sellers choose Replenagise over Slim4

1. Built for Shopify & Linnworks, not ERPs

2. Live in minutes, not months

4. Automation that executes

5. Transparent, affordable pricing

6. Multi-store & multichannel by default

Demand forecasting on every SKU, automated purchase orders and stock transfers, multiple stores and channels in one plan — connected directly to Shopify and Linnworks.

Forecasts That Become Purchase Orders

Stockful Alternative — FAQs

Stockful is a promising new Shopify inventory analytics and forecasting app — but it stops at recommendations, leaving purchase orders to you. Replenagise pairs the forecasting with execution: automated purchase orders and stock transfers, multiple Shopify stores in one view, and Amazon and eBay coverage through Linnworks.

Stockful launched on the Shopify App Store in March 2026, squarely aimed at merchants losing Stocky when Shopify retires it in August 2026. It is a Shopify-native analytics and forecasting layer: real-time stock tracking, daily inventory snapshots retained for up to two years (versus Shopify’s native 180 days), a dozen-plus scheduled reports, self-tuning per-SKU demand forecasts, reorder points and safety stock, Slack alerts, and an AI assistant — with every feature on every plan, from $19.99/month scaling on SKUs and locations. Early reviews are excellent: a 5.0-star rating at the time of writing.

Where it stops is deliberate: Stockful recommends, and you execute. It does not create or manage purchase orders or suppliers — its own comparison page points Stocky users back to Shopify admin for POs and stocktakes — it covers a single Shopify store per install, and it has no Amazon, eBay, Linnworks or 3PL integrations. Replenagise closes that loop: the forecast becomes a purchase order or stock transfer raised directly in Shopify and Linnworks, across all your stores and channels.

What Stockful does — and where it stops

Stockful is genuinely impressive for a product this young. The forecasting is thoughtfully built — out-of-stock days are excluded from velocity, promotion spikes are filtered out, models are backtested per SKU — the two-year snapshot history beats Shopify’s native 180 days, and flat all-features pricing from $19.99/month is refreshingly simple. A single-store Shopify merchant who wants sharper analytics and alerts than Shopify provides, and is happy raising purchase orders by hand, will get honest value from it.

But that is the design: a planning and analytics dashboard, not a replenishment platform. It launched in March 2026, its 5.0-star rating rests on a handful of early reviews, and it deliberately leaves purchase orders, supplier management and everything beyond one Shopify store out of scope. If your operation spans marketplaces, multiple stores, or simply more purchase orders than you want to key in by hand, Replenagise does the whole job: forecast, reorder decision, and the purchase order or transfer itself — raised automatically in Shopify and Linnworks.

Stockful vs Replenagise: an honest comparison

Why Shopify sellers choose Replenagise over Stockful

Inventory Forecasting Software — FAQs

Replenagise is AI-powered inventory forecasting software for ecommerce. It forecasts demand on every SKU using stockout-adjusted velocity, seasonality, and trends — then turns the forecast into reorder points, order quantities, and automated purchase orders for Shopify and Linnworks.

Most inventory forecasting tools stop at a trend line. You still have to decide what the chart means, how much to buy, and when. Replenagise closes that gap: every forecast comes with a recommended reorder point, safety stock level, and exact order quantity per SKU.

The forecasting engine adjusts for stockouts — so lost sales do not drag your demand history down — and detects seasonality and trend shifts automatically. The result is inventory forecasting that feeds real buying decisions, not another report to interpret.

A forecast you can actually order against

Accuracy only matters if it changes what you buy. Replenagise pairs its forecasting engine with the full replenishment workflow — reorder points, supplier lead times, purchase orders, stock transfers — so better forecasts become fewer stockouts, less overstock, and more cash back in the business.

It works wherever you sell: native Shopify integration for single-store and multi-store brands, and deep Linnworks integration for multichannel sellers across Amazon, eBay, Shopify and beyond.

More Resources

Control who can access your account and what they can do. Replenagise supports two roles: Admin (full access) and Viewer (read-only). Viewers can browse dashboards, forecasts, and reports but cannot edit settings, trigger syncs, raise purchase orders or raise transfers.

User Permissions

Channels represent your sales sources — Amazon UK, Shopify, eBay, Zalando, and any other marketplace connected through Linnworks. You can control which channels appear in your dashboard filters and, more importantly, which ones are included in your sales metrics and forecasting calculations.

Channel Configuration

Locations are the physical warehouses and fulfilment centres where your inventory is held. Replenagise pulls these directly from Linnworks and tracks stock levels at each one. You can choose which locations appear in your dashboard filters without affecting the underlying stock data.

Stock Locations

Properties are the extended attributes attached to your products in Linnworks — things like Brand, Collection, Season, Colour, or any custom fields you've defined. Replenagise uses these as powerful filter dimensions across your dashboard, forecasting, and reporting pages.

Product Properties

Replenagise syncs your order history, stock levels, and product data directly from Linnworks via API. Regular syncs happen automatically and pull in new orders since the last sync. If you notice missing orders or incomplete data, a full re-sync rebuilds your entire order history from January 2019 onwards.

Data Sync

Supplier settings define the key parameters that drive your replenishment calculations. Each supplier can have its own lead time, stock cover period, and minimum order quantity. These values feed directly into the Order Qty formula that determines how much to reorder.

Supplier Settings

Warehouse mapping connects each sales channel to its fulfilment location and sets the minimum stock cover required at that location. This is essential for accurate transfer quantity calculations — the system needs to know which warehouse ships orders for which channel.

Warehouse & Channel Mapping

The forecasting page provides 12-month demand projections for every product group using five statistical models. You can view forecasts in units or revenue, override individual months, compare model accuracy, and export everything to CSV for further analysis.

Switch to Smarter, Simpler Replenishment

Inventory Planner Alternative — FAQs

Inventory Planner by Sage is a capable tool — but many Shopify and Linnworks sellers do not need enterprise-grade pricing to get serious replenishment. Replenagise delivers demand forecasting, automated purchase orders, and multi-store stock transfers at a price built for growing brands.

Inventory Planner (now part of Sage) is a mature forecasting and purchasing tool, popular with larger multichannel retailers. For many growing Shopify and Linnworks sellers, though, it brings more price and complexity than the job requires.

Replenagise covers the jobs you actually buy this software for — demand forecasting on every SKU, reorder points and safety stock, purchase orders, and replenishment reporting — and goes further on automation: POs and stock transfers that do not just get suggested, but raised straight into Shopify and Linnworks, automatically if you want.

Serious planning should not require an enterprise budget

Inventory Planner earns its reputation with established brands: broad integrations, deep reporting, enterprise-grade planning — at a higher price point that can be steep for smaller stores. Replenagise is purpose-built for Shopify and Linnworks sellers who want the same core intelligence with more automation and a friendlier bill.

Switching is straightforward: connect your store via secure API and Replenagise pulls in products, stock levels, and sales history automatically. Forecasts and reorder recommendations are live from day one — no CSV migrations, no implementation project.

Linnworks Inventory Management — FAQs

Replenagise is the leading inventory planning platform for Linnworks. Connect via the Linnworks API, forecast demand on every SKU across Amazon, eBay, Shopify and all your channels, and raise automated purchase orders and stock transfers straight into Linnworks.

Linnworks is brilliant at multichannel operations — orders, listings, shipping, and stock levels across Amazon, eBay, Shopify and more. What it leaves to you is the hardest question in the business: what to buy, how much, and when.

Replenagise answers it. It connects directly to your Linnworks account, forecasts demand for every SKU using stockout-adjusted velocity, seasonality, and supplier lead times, and turns those forecasts into reorder points, safety stock, and purchase orders — raised straight into Linnworks with one click, or fully automated.

Linnworks runs your orders. Replenagise plans your stock.

Replenagise is not another order management system. It is the demand planning and replenishment layer that sits on top of Linnworks — so you keep the operations platform you know, and add the forecasting and buying intelligence it does not provide natively.

And as you grow, it grows with you: the same engine powers Shopify sellers, single-store and multi-store — so if your stack changes, your replenishment process does not break.

Netstock Alternative — FAQs

Netstock is demand planning software built around ERPs. Replenagise delivers the same core intelligence — demand forecasting, safety stock, automated replenishment — connected directly to Shopify and Linnworks, with transparent pricing and no ERP required.

Netstock is a capable demand and supply planning tool, designed to sit on top of ERPs like NetSuite, Sage, and SYSPRO. That is a great fit for distributors and manufacturers — but if you sell on Shopify, Amazon, or eBay, an ERP-first tool adds cost and complexity you may not need.

Replenagise connects directly to Shopify and Linnworks instead. You get demand forecasting on every SKU, reorder points and safety stock, supplier lead-time planning, and purchase orders raised straight into your platform — live in minutes via API, not an implementation project.

Demand planning without the ERP overhead

Netstock shines when your operations run through an ERP and your planning spans wholesale, distribution, or manufacturing. Replenagise is the equivalent intelligence for ecommerce operators: purpose-built for Shopify and Linnworks, multichannel via Amazon, eBay and more, and focused on automating the replenishment loop end to end.

If your stack is an ecommerce platform rather than an ERP, you should not have to pay for — or implement — the ERP layer to get world-class replenishment.

Predictable Pricing, Serious Replenishment

Prediko Alternative — FAQs

Prediko is a capable Shopify inventory app — with pricing that steps up as your store’s revenue grows. Replenagise prices by catalog size instead, includes every feature on every plan, and adds Linnworks multichannel coverage — from $37.99/month.

Prediko is one of the better-known inventory apps for Shopify: AI sales forecasting, purchase order management, and inventory reporting, with plans tied to your store’s revenue — $49/month up to $100k in annual revenue, $119 up to $500K, $199 up to $2M, and a quote-based Enterprise tier above that. There is nothing wrong with that model, but it means your software bill rises with your sales even when your catalog and workload stay the same.

Replenagise ties price to the size of the job instead: how many products you manage. Plans run from $37.99/month for 200 products to a flat, public $249.99/month for unlimited products — every feature on every tier, a 20% discount on annual billing, and a 14-day free trial. Connect Shopify or Linnworks via secure API and forecasts, reorder points, and purchase orders are live in minutes.

Pay for your catalog, not your growth

Prediko is a credible choice if you sell only on Shopify and are comfortable with revenue-based pricing — it is well reviewed and covers forecasting and purchasing well. The differences that matter are the pricing model and platform reach: Replenagise gives you price certainty as you scale, publishes its top-tier price instead of routing large stores to a quote, and extends the same planning to Linnworks-connected channels like Amazon and eBay.

Switching is not a project. Connect your store via secure API and Replenagise pulls in products, stock levels, and sales history automatically — forecasts and reorder recommendations are live the same day, with no CSV migrations.
