ReplenishRadar vs Monocle: Beyond Shopify Only

The short version. Monocle and ReplenishRadar both turn sales history into forecasts and purchase orders. Monocle is built for Shopify stores. Its pitch is a forecast that does not mistake a stockout for low demand. ReplenishRadar puts Shopify and Amazon in one forecast, shows the model behind each tip, and plans the FBA send. Pricing differs too. Monocle prices by your revenue. We price by stores and SKUs.

What Monocle does

This section comes from Monocle's Shopify App Store page and its own site, read on November 3, 2026 (apps.shopify.com/forecast, monocleapp.co). It lists:

• Forecasts that "clean the stockouts out of your sales history," with reorder dates and stockout dates.
• One-click purchase orders with lead time, safety stock and coverage built in.
• ABC-XYZ analysis and market basket analysis.
• Several locations, low-stock alerts, custom reports and a link to ChatGPT or Claude.
• Free data moves from Stocky.

The site says it fits stores with 20 or more SKUs and at least 12 months of order history. It is Shopify only. Its App Store page shows 4.5 stars from 29 reviews.

What it costs

There are four plans. Each has a 14-day free trial. Tiers follow yearly revenue.

Plan	Monthly	Yearly revenue	Adds
Starter	$47	Up to $360k	AI forecasts, purchase orders, ABC-XYZ
Premium	$67	Up to $720k	Faster forecasts, better reorder tips
Elite	$89	Up to $1.44M	Concierge setup, custom analytics
Ultimate	$129	No cap listed	Priority support, roadmap voting

ReplenishRadar Standard is $99 a month at launch pricing through December 31, 2026. It is $119 after that. It covers 2 stores and 2,000 SKUs. Growth is $199 ($249 after) for 5 stores and 20,000 SKUs. Scale is $499. See the pricing page. Monocle is cheaper at the start. Above $1.44M in revenue, its Ultimate plan is $129 a month. Our price does not follow your sales. Standard stays $99 if you fit 2 stores and 2,000 SKUs. Growth is $199 if you do not.

What ReplenishRadar does

• We read Shopify and Amazon sales for each SKU and plan the total demand.
• We sort each SKU by demand pattern: steady, seasonal, patchy or variable. We pick a method that fits. You can see the model and inputs behind each tip.
• We set reorder dates from supplier lead times and minimums. Draft purchase orders wait for your approval.
• On Growth and up, we create the FBA inbound shipment plan in Amazon through the SP-API. On Standard, we prepare an upload file.

We do not offer market basket analysis or a Stocky data move.

Where Monocle fits better

• Shopify is your only channel, and you want the lowest start price at $47 a month.
• Your history has stockouts in it. You want the forecast to fix them by design.
• You want market basket analysis for cross-selling.

Where ReplenishRadar is the better fit

• You sell on Amazon. Monocle's site never mentions it, so Amazon demand stays out of its forecast.
• Stock goes to FBA, and you want the shipment plan built for you.
• Your revenue is growing, and you do not want your software bill to grow with it.
