Best Automated Inventory Replenishment Software (2026): Pricing Guide

TL;DR: There is no single best automated inventory replenishment system for every Shopify store. The seven systems publish different prices and different combinations of single- or multi-channel planning, location workflows, purchase-order management, raw-material planning, and financial analysis. Match the system to the decisions you need it to support, then validate it with your own products, lead times, and ordering workflow.

Last updated: August 2026

Pricing and product details checked on official vendor pages on August 19, 2026. Prices can change and may exclude add-ons, implementation, usage, or tax.

Disclosure: Forthcast publishes this comparison and is one of the products covered. The seven entries are ordered alphabetically, not ranked, and we did not conduct a hands-on benchmark of competing products. “Best for” below means the clearest fit indicated by the vendor’s public pricing and feature descriptions, not a performance award.

Automated Inventory Replenishment Systems Compared

The seven systems differ most in pricing grain, platform scope, and how far they carry a plan into purchase-order or transfer workflows. This table is a screening guide based on current official vendor pages, not a substitute for a trial with your own data.

System	Public starting price	Planning and replenishment scope	Clearest fit from public information
Cogsy	$199/month after a 14-day trial	Demand planning, replenishment alerts, purchase orders, backorders, multi-location support, subscriptions, and event planning	Online brands that want one published all-in-one plan with event and new-product planning
Fabrikatör	$79/month for the lowest revenue band when billed $950 yearly	Forecasting, stock replenishment, purchase orders, bundles, analytics, backorders, and freight planning	Brands comfortable with revenue-banded pricing that want a broader planning workspace
Forthcast	$19.99/month flat with a 14-day trial	Shopify per-SKU forecasts, reorder points and alerts, safety stock, stockout tracking, and draft purchase orders for review	Shopify merchants seeking a focused forecasting and reorder-review workflow at a flat subscription price
Inventory Planner by Sage	Free to install; current subscription price requires a quote	Forecasting, replenishment, multi-location planning, multi-channel reporting, cash-flow and profitability analysis, and purchase orders	Retailers that need broad planning and financial analysis and are willing to request pricing
Prediko	From $49/month for stores below $100,000 in annual revenue, with a 14-day trial	Demand and supply planning, buying alerts, purchase-order management, transfers, bundles, multiple stores and locations, and an optional raw-material add-on	Shopify brands that want revenue-scaled planning across purchasing, locations, or raw materials
StockTrim	From $39/month with a 14-day trial	Variant and new-product forecasts, order recommendations, purchase orders, multi-location planning, minimum-order quantities, and container constraints	Merchants that want ordering constraints and scenario inputs alongside demand forecasts
Sumtracker	$119/month for the Replenish plan up to 2,500 orders per year, with a 14-day trial	Reorder suggestions, 12-month forecasts, purchase orders, stock transfers, bundles, and multi-channel inventory sync	Merchants that want replenishment planning and inventory operations across channels

The prices are not directly equivalent. Cogsy publishes an all-in-one monthly plan, Fabrikatör and Prediko vary pricing by revenue, StockTrim varies plans by catalog or business scale, and Sumtracker ties the displayed Replenish tier to annual order volume. Inventory Planner’s Shopify listing says free to install but does not publish the ongoing subscription price. Forthcast publishes one flat Shopify subscription. Compare the total price at your actual revenue, SKU count, order volume, locations, users, and required add-ons.

How We Compared the Seven Systems

This comparison uses only public first-party vendor pricing pages, official product pages, and official Shopify App Store listings checked on August 19, 2026. We recorded what each source explicitly says about price, trial, forecasting, replenishment, purchase orders, integrations, locations, and plan limits.

We did not assign numerical scores because the public descriptions do not establish comparable forecast accuracy, implementation effort, support quality, or realized financial results. Vendor claims about saving time, reducing stockouts, or improving cash flow are not treated as independently verified outcomes here.

A listed feature also does not prove that two systems implement it in the same way. “Purchase orders,” for example, can mean a draft, a recommendation, a management workspace, or an automated creation step. Confirm the exact approval, editing, sending, receiving, and accounting workflow in a demo or trial.

Cogsy: All-In-One Planning at a Published Monthly Price

Cogsy’s official pricing page publishes one $199-per-month plan after a 14-day trial. It includes demand planning, replenishment alerts, purchase orders, backorders, multi-location support, subscriptions, growth planning, marketing events, and new-product planning.

That combination makes Cogsy a plausible shortlist option for online brands that want forecasting connected to upcoming events and product launches. Its listed integrations include Shopify, Amazon, ShipBob, Google Analytics, and several operations tools, so it is broader than a Shopify-only forecasting workflow.

The tradeoff is straightforward: the public entry price is higher than the lowest listed prices in this comparison. A trial should test whether the event calendar, backorder handling, integrations, and planning workflow justify that difference for the people who will use them.

Fabrikatör: Revenue-Banded Inventory Planning

Fabrikatör’s official pricing page displays $79 per month for the $0–$500,000 annual-revenue band when billed $950 yearly. The page says pricing supports growth, so a merchant should select its actual revenue band and billing cadence before comparing total cost.

The public plan description includes accurate stock replenishment, unlimited SKUs and users, bundle planning, demand forecasting, and live chat. Fabrikatör’s broader product navigation also covers purchase orders, analytics, backorders, and freight planning.

This structure may suit a growing brand that wants multiple planning functions and prefers a revenue-based tier to a SKU or user limit. Check the price for your current band and expected growth rather than treating $79 as a universal price.

Forthcast: Focused Shopify Forecasting and Reorder Review

Forthcast’s official Shopify App Store listing publishes a flat $19.99 monthly subscription and a 14-day trial. Forthcast provides per-SKU demand forecasts extending roughly 12 months, store-wide reorder points and alerts, safety-stock planning, stockout and lost-sales tracking, anomaly signals, and draft purchase orders.

Forthcast provides per-SKU forecasts, store-wide reorder points, and draft purchase orders for merchant review; it does not place orders automatically. The merchant decides whether to edit and send a draft. It is Shopify-specific and does not provide landed-cost accounting, multi-channel inventory sync, or multi-warehouse netting.

The focused scope and flat price can fit a Shopify merchant that wants forecast and reorder decision support without a broader inventory-operations suite. It is a weaker fit when the required workflow depends on synchronizing several commerce channels, netting inventory across warehouses, tracking landed costs, or sending purchase orders without merchant approval.

Inventory Planner by Sage: Broad Planning with Quote-Based Pricing

Inventory Planner by Sage’s official Shopify App Store listing says the app is free to install, additional charges may apply, and merchants must request a quote for subscription pricing. An older fixed monthly price should not be used as the current price.

The official listing describes demand forecasting, automated replenishment, multi-location stock planning, multi-channel reporting, cash-flow planning, inventory turnover, SKU-level profitability analysis, workflow automation, and purchase orders. It also lists integrations such as Amazon, Cin7, Linnworks, QuickBooks, and ShipBob.

This is the broadest publicly described financial and multi-source planning scope in this group. It may fit a retailer that needs those analytical and integration layers, but the lack of a public ongoing subscription price means the buying comparison must include a current quote and the specific onboarding or service terms offered.

Prediko: Revenue-Scaled Planning with Location and Raw-Material Options

Prediko’s official pricing page starts at $49 per month for stores with less than $100,000 in annual revenue and offers a 14-day trial. Pricing rises across revenue bands, and its annual plans can be billed quarterly or annually.

The published plan includes unlimited users, SKUs, and purchase orders; revenue and inventory forecasting; purchase-order management; buying alerts; multiple stores and locations; and customized reports. Prediko also lists inventory transfers, bundles, and an optional raw-material forecasting and bill-of-materials add-on.

Prediko may fit a Shopify brand that wants a purchasing workspace that can expand into location transfers or raw-material planning. The important cost check is the merchant’s current revenue band plus any add-on, not only the advertised starting price.

StockTrim: Forecasting with Ordering Constraints

StockTrim’s official Shopify App Store listing starts at $39 per month for its Ecommerce Starter plan and includes a 14-day trial. The displayed starter tier covers 1–500 SKUs and up to $1 million in gross merchandise value; other listed plans use different product limits and billing choices.

The official listing says StockTrim forecasts demand, recommends order quantities, and generates purchase orders. It also lists forecasting by variant, new-product simulations, multi-location planning, minimum-order quantities, and container-size constraints.

Those public features make StockTrim worth evaluating when supplier constraints or new-product assumptions matter to the order recommendation. Confirm which pricing track applies to your ecommerce setup and whether its purchase-order automation uses the approval controls your team requires.

Sumtracker: Replenishment with Multi-Channel Inventory Operations

Sumtracker’s official Shopify App Store listing shows the Replenish plan at $119 per month for up to 2,500 orders per year, or $1,199 per year, with a 14-day trial. Higher order volumes use higher pricing, and its lower-priced Manage plan does not include the displayed replenishment feature set.

The Replenish plan lists purchase orders, stock transfers, inventory replenishment, 12-month forecasting, automated reorder suggestions, and sales-velocity calculations. The broader app description includes inventory synchronization for Shopify, Amazon, eBay, Etsy, and Walmart, as well as bundles, partial receiving, and landed costs.

Sumtracker may fit a merchant that wants replenishment and purchase-order work tied to multi-channel inventory operations. Compare the Replenish plan at your annual order volume and verify the channels, locations, bundle logic, and receiving process you need.

Which Replenishment System Fits Which Workflow

The right shortlist follows the operational boundary of the decision. Start with the system of record, the people approving purchases, the locations or channels that must be considered, and the constraints that change an order quantity.

• Focused Shopify forecast and reorder review: Forthcast has a flat $19.99 monthly price and keeps purchase-order sending under merchant control.
• Event, launch, and subscription-aware planning: Cogsy publicly groups these functions with replenishment and purchase orders in one plan.
• Revenue-banded broader planning: Fabrikatör and Prediko both scale displayed pricing by revenue, with different operational features to test.
• Financial and multi-source analysis: Inventory Planner by Sage describes multi-channel reporting, cash-flow, turnover, and profitability analysis, but requires a pricing quote.
• Ordering constraints and new-product scenarios: StockTrim explicitly lists minimum-order quantities, container sizes, and new-product forecasts.
• Multi-channel sync plus replenishment operations: Sumtracker connects its Replenish plan to inventory sync, purchase orders, transfers, bundles, and receiving.

These are shortlist directions, not rankings. A system that offers more functions is not automatically better: unused scope can add cost and process complexity, while a narrowly scoped tool can be insufficient when a required channel, warehouse, accounting field, or approval step sits outside it.

What to Test Before Choosing Replenishment Software

A useful trial reproduces real purchasing decisions rather than only reviewing a dashboard. Test several products with different demand patterns and trace each input through forecast, recommendation, approval, purchase order, and receiving.

1. Reconcile the starting data. Check on-hand inventory, open purchase orders, variants, bundles, locations, stockout periods, and sales history against the system you already trust.
2. Inspect forecast assumptions. Use a stable seller, a seasonal product, a slow mover, and a new item. Confirm the forecast horizon, treatment of stockouts, events, and the way uncertainty is shown.
3. Rebuild a real reorder decision. Enter actual supplier lead time, safety stock, minimum-order quantity, case pack, and any location or channel rules. Compare the suggested quantity with a recent order and investigate the difference.
4. Trace purchase-order control. Determine whether the system recommends, drafts, creates, sends, edits, receives, or accounts for a purchase order. Identify who approves each step.
5. Calculate the actual subscription. Include the correct revenue, order, SKU, location, channel, and add-on bands plus any implementation or service charge.
6. Define a review cadence. Decide who handles exceptions, supplier delays, promotions, launches, low-history items, and changes in forecast bias after the trial.

The output should be a documented fit decision: the required workflows the system covers, the gaps your team will retain, the recurring price at your current scale, and the evidence that its recommendations reconcile to your operational data.

Frequently Asked Questions

What is the best automated inventory replenishment system for Shopify?

There is no universal best system. Forthcast publishes a flat $19.99 monthly Shopify subscription, while Cogsy, Fabrikatör, Inventory Planner, Prediko, StockTrim, and Sumtracker publish different pricing models and combinations of planning, purchase-order, location, channel, and financial workflows. Choose by required scope and validate with your own data.

How much does automated inventory replenishment software cost?

Public starting prices in this comparison run from $19.99 per month for Forthcast to $199 per month for Cogsy. Fabrikatör starts at $79 when billed yearly, Prediko at $49, StockTrim at $39, and Sumtracker’s Replenish plan at $119 for its displayed order band. Inventory Planner requires a current quote for ongoing subscription pricing.

Does replenishment software place purchase orders automatically?

It depends on the product and configuration. Some vendors describe purchase-order creation or management, while others produce alerts, recommendations, or drafts. Forthcast creates draft purchase orders for merchant review and does not send orders automatically. Test the approval and sending steps before buying.

What data should I check during a replenishment software trial?

Check on-hand stock, open purchase orders, sales history, variants, bundles, stockout periods, supplier lead times, safety stock, minimum-order quantities, case packs, locations, and channels. Use actual past orders to see whether recommendations reconcile to the data and assumptions your team uses.

Should I choose replenishment software by its lowest advertised price?

No. Compare the price at your actual revenue, SKU count, order volume, users, locations, and channels, including required add-ons and services. Then compare that total with the exact planning, approval, purchase-order, receiving, and reporting workflows the system must support.
