Most people who search for an Inventory Planner alternative are not unhappy with the forecasting. They are trying to find out what it costs, cannot, and want to know whether there is something they can just buy. This page answers both halves of that.
Written 26 August 2026. Everything below about Inventory Planner was checked that day against its Shopify App Store listing, its own pricing page, and its own help centre. Those pages change. Check them yourself before you decide anything, and treat every dated claim as dated.
Inventory Planner by Sage is free to install on Shopify, and the listing's pricing section reads: "Pricing adapts to your business needs. Contact us to get a quote." It also carries Shopify's standard note that additional charges may apply separately from your Shopify invoice, which means the money does not land on the Shopify bill you already get.
Their own pricing page says the same thing in more words. It states that pricing is based on the volume of inventory you manage, that users are unlimited at no extra cost, and that implementation takes about four weeks on average. There is no number anywhere on it. Every button asks you to request pricing or book a demo.
So the honest summary is: nobody outside the company can tell you what Inventory Planner will cost your store. Not me, not a comparison site, not the person in a Facebook group who quoted you their number, because their number was scoped to their inventory.
Worth saying, because the rest of this page is more useful if you believe me here. Volume-based, quoted pricing is normal in software sold to larger retailers, and there are sound reasons for it. When the amount of work the system does varies by an order of magnitude between customers, one published price is either too high for the small end or too cheap for the large end. Implementation with a human attached costs real money and has to be priced. And a company selling to a 40-store multi-channel retailer is having a genuinely different conversation than one selling to a Shopify store with 800 SKUs.
Inventory Planner has been on the Shopify App Store since 15 January 2013 and holds 4.4 stars from 129 reviews as of today. Thirteen years is a long time to be wrong about how to sell your product.
The model has one cost for you specifically, and it is the reason you are on this page: you cannot budget for it without booking a call. If you are a store owner trying to work out whether this is a $60 decision or a $600 decision before spending an hour of your week, a quote-only price is a closed door.
Since I cannot tell you the price, the next most useful thing is what merchants have written down themselves. These are their claims in their own public reviews, not facts I can verify, and I am quoting them as reports rather than presenting them as the price list:
Three unhappy reviews out of 129 is not a portrait of the product. 84 percent of those reviews are five stars, and the recent positive ones name individual support staff and describe the platform as essential to running multi-channel purchasing. Both things are in the same listing and both are real.
What the three do tell you is the shape of the risk: an annual commitment, a price that is set per customer and can be reset, and a company whose ideal customer may be bigger than you. Inventory Planner is owned by Sage — its own help centre describes it as the sister company to Brightpearl, both owned by Sage — and it is sold alongside a retail operating system aimed at established multi-channel retailers. That is a fair description of where the product is pointed.
Here is the whole thing. No quote, no call, no implementation project.
Annual is two months free. Paid plans have a 14-day trial. Everything bills through the Shopify Billing API, so it appears on the Shopify invoice you already pay, and you can cancel any time by downgrading to Free or uninstalling. There is no contract and no per-order fee.
Note what that pricing implies about the target. The top plan is $99 a month. A store where inventory is complicated enough to need a four-week implementation is not the store I built this for, and $99 a month is the honest signal of that.
Proviand launched this summer. It has no review history, and it is built and maintained by one person, which is a risk you should count rather than wave away. It reads Shopify only. It does no stock transfers, no warehouse counts, no multi-channel or marketplace inventory, no cash-flow or open-to-buy planning, and it has no report builder. There are no approval workflows, so if two people have to sign off on a purchase order, it will not model that.
What it does is one thing: read your Shopify sales history and tell you what to order today, how much, and exactly why, then turn that into a purchase order you send to a supplier. If that is the whole job, the surface area is the feature. If it is a third of the job, it is a gap.
If you are mid-way through evaluating Inventory Planner, ask for the quote anyway. It costs you a call, and if your store is genuinely multi-channel you will learn something about what a real implementation looks like. Ask what happens at renewal, and whether the quote is annual.
While you wait for it, install Proviand's free plan. It reads the order history you already have, so the buying table is populated the same day, and it costs nothing to leave running next to whatever you use now. Then compare on the morning you actually have to place an order, which is the only test that has ever told anyone anything useful.
If the quote comes back and it is right for you, take it. You will at least know what you decided between.
