For any business that buys goods before it sells them, inventory is the largest single use of working capital on the balance sheet. The tools that manage it fall into two camps: those that forecast what to buy next, and those that account for what was already bought badly. Most owners need one of each, and rarely realize the distinction until cash gets tight.
Pricing and features were verified against each vendor’s published material in September 2026.
1. Cash Margin Partners
Cash Margin Partners occupies the second camp deliberately. Rather than forecasting the next order, it measures how much cash is already immobilized in stock that has stopped selling, and returns that figure at the individual product level.
The platform connects to Shopify, Square Point of Sale, or Lightspeed Retail X-Series through read-only authorizations, or accepts a catalog and sales export. It reports cash-at-risk across 30, 60, and 90 day horizons, distinguishing dead stock, meaning inventory with no verified sales history over the measured window, from slow-moving inventory that still sells below a viable rate.
Those numbers are model forecasts built from the business’s own trading history, and the product presents them as forecasts rather than as certainties. A ranked recovery plan follows, covering markdown, bundling, and liquidation, alongside a marketplace for stock leaving the business.
Best for: owner-operated retailers who need to convert immobilized stock back into working capital.
Pricing: free, with no credit card and no time limit. The marketplace charges a success fee only on a completed transaction.
Limitation: it generates no purchase orders and runs no replenishment, so a business whose core weakness is buying discipline needs a planning tool alongside it.
2. Inventory Planner by Sage
Inventory Planner is the most complete buying tool in this group. It forecasts demand with seasonality adjustment, generates purchase orders against supplier lead times, and runs open-to-buy planning against a merchandise budget, which is a discipline most independent operators never formalize.
Its overstock reporting covers units and cost value together, a combination several competitors leave split across two reports.
Best for: multi-channel businesses running a formal merchandise budget.
Pricing: custom, quoted behind a demo request. A lighter Shopify app lists separately at $119.99 per month.
Limitation: pricing isn’t published, so an owner can’t size the decision without a sales call.
3. Prediko
Prediko is a Shopify-native planning app built around a single promise: restock on time. It forecasts demand, builds purchase orders, manages suppliers, and tracks raw materials for businesses that manufacture.
It holds a 4.9 rating across 248 reviews on the Shopify App Store and reports serving more than 2,500 merchants, which is a deeper evidence base than most tools in this category can show.
Best for: Shopify-only businesses whose costliest error is a stockout.
Pricing: banded by annual sales volume, from $49 per month.
Limitation: Shopify only, with no connector for a physical point-of-sale system, and output expressed in units and weeks of cover rather than in currency.
4. Netstock
Netstock brings formal inventory discipline to businesses already running an ERP. It classifies every product by sales value and velocity, recalculates safety stock against demand variability and supplier reliability, and generates replenishment orders that respect minimum order quantities.
Where surplus exists at one site and demand at another, it suggests transfers rather than markdowns, which is a lever only multi-site operators can pull.
Best for: multi-location retailers and distributors with an ERP in place.
Pricing: from $900 per month.
Limitation: every named connector is an ERP, placing it out of reach for businesses running a till and a spreadsheet.
5. Cin7
Cin7 is a full inventory and order management system spanning purchasing, warehousing, wholesale, and multi-channel sales. Demand forecasting arrived through its 2024 acquisition of Inventoro and now ships as a paid add-on called ForesightAI.
The breadth is the point and the cost. Adopting Cin7 replaces several systems at once, which is valuable for a business drowning in disconnected tools and disproportionate for one that isn’t.
Best for: businesses consolidating three or four systems into one.
Pricing: from $349 per month, rising to $1,199 for the top tier, with forecasting priced separately.
Limitation: implementation is a migration measured in weeks, and no physical point-of-sale connector is listed.
6. Toolio
Toolio replaces the merchandising spreadsheet for companies large enough to employ someone who lives in it. Assortment planning, financial merchandise planning, open-to-buy, and allocation all sit in one collaborative model, and its client list includes Peloton, Bombas, and Ariat.
Best for: multi-store or multi-category retailers with a dedicated planning function.
Pricing: custom, with no published rate.
Limitation: no self-serve path and no published price, and every integration logo on the company’s site currently carries a “coming soon” label, so connector availability is worth settling before signing.
7. Streamline
Streamline handles the difficult end of forecasting: intermittent demand, long supplier lead times, and stock moving between echelons of a distribution network. Its 4.4 rating across 263 reviews on G2 is the deepest review base of any planning tool in this list.
Best for: distributors ordering against lead times measured in months.
Pricing: custom, quoted per deployment.
Limitation: parts of the company’s documentation still describe a desktop application while the marketing describes a cloud platform, so the deployment model is worth confirming in writing.
Which camp to buy first
The sequence depends on where the loss is happening. A business that keeps running out of its best sellers has a forecasting problem and should buy a planning tool. A business whose stockroom is full while the bank account is thin has already made the buying mistake, and better forecasting won’t sell what is sitting there.
The financing environment makes the second case more urgent than it used to be. Sixty percent of small employer firms applied for financing in the prior twelve months, and among applicants only forty-two percent received the full amount requested, according to the Federal Reserve’s 2026 Report on Employer Firms. Rising costs of goods, services, and wages was the top financial challenge reported, and among retail firms specifically, sixty-nine percent cited tariff-related cost increases.
When external funding arrives short, the capital already committed to inventory becomes the most available source of cash a business has. Measuring it is the first move, and it doesn’t require a purchase order.
