How Much Does Inventory Planner by Sage Cost? (2025 TCO)

Inventory Planner by Sage is one of the most capable demand-forecasting tools a Shopify or multi-channel brand can buy. It is also one of the hardest to price. Since Sage absorbed it through the 2022 Brightpearl acquisition, the only number you can find on the open web is the Essentials plan at $119.99/month. Everything above that (Standard, Premium, Enterprise) is a quote you have to ask for. This post breaks down what brands actually pay at each revenue stage, what the real add-ons are, and how to budget the full first-year cost before you sign a 12-month contract.

A quick definition up front: total cost of ownership (TCO) means the all-in number, not the sticker. For software like this, TCO is the annual subscription plus implementation, plus the cost of the tier you get pushed into as you grow. The list price is the smallest part of that picture.

What Inventory Planner actually charges (and what it won't tell you upfront)

Here is the uncomfortable truth about Inventory Planner's pricing: there isn't a price list. The vendor's pricing page says cost is "based on the volume of inventory you manage," gives you unlimited users, and then routes you to a "Request pricing now" button. The single exception is the Essentials plan, which lives on the Shopify App Store at a confirmed $119.99/month for a single-warehouse, Shopify-only store with basic forecasting and a 14-day trial.

For every other tier, the meter runs on two dials: your gross merchandise value (GMV) and your number of replenishable SKUs. Cross a threshold on either and you move to the next band. That matters because the bands are not a smooth slope. They are steps. When I talk to founders running a brand in the $3M to $10M range, the recurring surprise is not the headline price, it is the mid-contract jump: they signed at one tier, added a second warehouse or a wholesale channel, and found the renewal quote came back at a materially higher band than they had modeled.

The opacity is a deliberate sales motion, not an accident. A quote-based model lets the vendor price to your revenue rather than to a public rate card, which is good for them and bad for your ability to budget. The defense is simple: before you ever get on a sales call, write down your GMV, your replenishable SKU count, your warehouse count, and your channel mix. Those four numbers determine your quote, so knowing them lets you sanity-check whatever the rep comes back with.

Plan-by-plan breakdown: Essentials, Standard, Premium, Enterprise

There are four tiers. Only the first has a confirmed price. The rest are reconstructed from aggregated merchant quotes and analyst teardowns, so read every non-Essentials figure below as an estimate, not a published rate.

Essentials ($119.99/month, confirmed). Single warehouse, Shopify only, basic forecasting, unlimited users, 14-day trial. Built for stores under roughly $2M GMV that need replenishment math better than a spreadsheet. At least one reviewer describes it as intentionally thin, a "bare bones" option that exists to make the upgrade look worthwhile.

Standard (roughly $250 to $300/month, estimated). This is the real working tier for most growing DTC brands. Multi-channel (Shopify plus Amazon and others), multiple warehouses, unlimited users, custom annual quote. Independent reviewers have cited base figures from $249.99 up toward $299, which is consistent with the $250 to $300 range. Fits brands roughly $3M to $10M GMV.

Premium (roughly $600 to $900/month, estimated). Adds the Sage Copilot AI assistant and deeper analytics (Option Insights). Positioned for $10M to $25M GMV brands that want AI-assisted forecasting. The Copilot capability is the upgrade trigger here, not a separate add-on.

Enterprise (roughly $1,200+/month, estimated, custom terms). Custom SLAs, a dedicated customer success manager, bespoke integrations, and formal Order Forms with service allocations and overage charges if you exceed them. Direct Sage sales only, for high-volume or complex operations.

The real add-ons: warehouses, SKUs, Copilot AI, and implementation

The word "add-on" is misleading for Inventory Planner, because most of what feels like an add-on is actually a tier change. There is no published per-warehouse or per-SKU surcharge. Add a warehouse, and instead of a tidy incremental fee, you can find yourself pushed up a band. Some independent reviewers have reported rough figures (around $80 per extra warehouse per month, around $15 per 1,000 SKU variants), but Inventory Planner does not confirm these, so treat them as reported estimates rather than a rate card.

Sage Copilot, the AI assistant that surfaces priority replenishments, late purchase orders, and missing cost data, is the same story. It is not a checkbox with a disclosed surcharge. It is bundled into Premium. So "adding AI" means moving from Standard to Premium, which the estimates put at roughly 2 to 3 times the cost. Budget for the tier, not the feature.

Then there is implementation. For Essentials and Standard, light onboarding is usually self-serve and folded in, call it $0 to $1,500. For Premium and Enterprise, where you are wiring up multiple systems and migrating historical data, an independent analyst range of $2,000 to $10,000 one-off is realistic, and it is typically incorporated into or billed alongside the contract rather than as a clean separate line. The pattern we see again and again with brands switching forecasting tools: the subscription gets all the scrutiny and the implementation cost gets discovered late. Ask for it itemized in the quote.

Putting subscription and implementation together gives you the only number that actually matters, the first-year TCO. A $3M brand on Standard with light onboarding lands around $3,500 to $5,600. A $15M brand on Premium with heavier setup lands around $10,200 to $20,800.

What DTC brands are actually paying: user reports and review evidence

Estimates are one thing. What merchants say they paid is another, and the Shopify App Store reviews are blunt. One reviewer in July 2025 reported that their subscription cost "was increased threefold" after the Sage transition. Another, in October 2025, referenced a $4,000 annual fee (about $333/month) in the context of a billing dispute. An Essentials user in January 2025 was sharper still, writing that Sage "took a great product, jacked up the price, and offer a TERRIBLE bare bones option to make you think upgrading is worthwhile."

Hold those against the fact that the product itself rates 4.6 to 4.8 stars. Both things are true: the forecasting is genuinely good, and the post-acquisition repricing genuinely stung a cohort of long-time users. Negative reviewers are also the most motivated to post specific dollar figures, so read the amounts as real data points but not as a representative average.

So what does a real brand spend? When we work through this with founders, the rough shape is consistent. A $3M brand that needs multi-channel forecasting is usually looking at $3,000 to $5,000 all-in for year one on Standard. A $15M brand that wants the Copilot AI layer is realistically in the $10,000 to $20,000 range once implementation is counted. The single most common mistake we see is a brand budgeting the Essentials price in their head, then signing a Standard or Premium contract that is three to five times that, because nobody told them the working tier was never $119.99 to begin with.

Inventory Planner vs alternatives: the true-cost comparison

Inventory Planner's pricing opacity is easier to stomach once you see the field. On entry price and transparency, the alternatives mostly win.

The read is not "Inventory Planner is overpriced." It is that you are paying a premium for forecasting depth and a multi-channel data model, and you are paying it inside an annual contract with quote-based pricing. If your problem is genuinely sophisticated demand planning across channels and warehouses, that premium can pay for itself in avoided stockouts and freed-up working capital. If your problem is simpler, a flat-rate tool like Forthcast or a transparent tiered tool like Prediko clears the same job for a fraction of the cost and lets you leave any month. For a broader look at how this fits into the tool-spend picture for a growing DTC brand, modeling these software decisions before signing is exactly the kind of work a fractional CFO does at the $3M to $15M revenue stage.

Is Inventory Planner worth the cost? A framework for your revenue stage

Strip out the noise and the decision comes down to your revenue stage and how much money sloppy inventory is currently costing you.

A commonly cited rule of thumb in inventory-software benchmarking (source varies across practitioners): a reasonable annual budget for planning software is roughly 0.5% to 1.5% of COGS. At a typical 50% gross margin that translates to about 0.25% to 0.75% of GMV. Inventory Planner sits at the low end of that band for mid-market and above, which is the quiet case in its favor: as a share of GMV, the tool gets cheaper the bigger you are, from roughly 0.48% at $300K GMV on Essentials down under 0.05% at $50M+ on Enterprise.

Here is the staged framework:

Under ~$2M GMV: Essentials or a cheaper alternative. At this size your forecasting needs are modest and the $119.99 Essentials plan, or a flat-rate tool, is plenty. Do not buy Standard's machinery you will not use.

$2M to $10M GMV: Standard, but run the numbers before signing. This is where the tool earns its keep if you are losing real money to stockouts or overstock. When we work through this with operators, the test is concrete: if cleaner replenishment would free even $50,000 of trapped working capital or recover a few percent of lost sales, a $3,500 to $5,600 year-one cost is trivial. If you cannot point to that pain, you are buying overhead.

$10M+ GMV: Premium or Enterprise, evaluate the Copilot ROI. At this scale the AI layer and analytics can be worth the 2-to-3x step up, but only if you have the SKU complexity to feed it. Get the implementation cost itemized and confirm the GMV band you are quoting into, because this is exactly where the step-function jumps bite hardest.

Whatever stage you are at, the move is the same: model the full first-year TCO, not the monthly sticker, and confirm which band your GMV and SKU count put you in before you commit to twelve months.

The mistake is almost never overpaying for the tool. It is signing a quote-based annual contract while still mentally anchored to the $119.99 Essentials price, then discovering at renewal that the working tier was always two or three times that, and the next warehouse pushes it higher again. Price the band you will actually be in a year from now, not the one on the App Store.

Sources and methodology

The only publicly confirmed Inventory Planner price is $119.99/month for the Essentials plan, listed on the Shopify App Store. Every other tier price in this post is a third-party estimate, derived from aggregated merchant-quote data and independent analyst teardowns, and is labeled as such throughout.

Tier estimates (Standard ~$250 to $300, Premium ~$600 to $900, Enterprise ~$1,200+) come primarily from CheckThat.ai's 2026 pricing analysis, which aggregates real merchant quotes and identifies GMV and replenishable SKU count as the two primary cost drivers. These figures are not official and should be read as ranges, not rates.

Different sources publish slightly different structures. Forthcast's 2026 comparison lists tiers at $299 and $599; an ATTN Agency review cites a $249.99 base plus reported per-warehouse (~$80) and per-SKU (~$15 per 1,000 variants) figures and a 12-month mandatory contract. These are not mutually exclusive: they likely reflect different customer profiles, vintage quotes (pre- versus post-Sage), or different plan configurations. We have presented the per-warehouse and per-SKU figures as reported estimates because Inventory Planner does not confirm them.

User-reported spend comes from Shopify App Store reviews: a reported threefold increase (July 2025), a $4,000 annual figure cited in a billing dispute (October 2025), and an Essentials reviewer's "bare bones" complaint (January 2025). Reviews skew toward motivated negative posters, so we have balanced them against the product's consistent 4.6 to 4.8 star rating.

The acquisition history (Brightpearl acquired Inventory Planner in September 2021, Sage acquired Brightpearl in January 2022, rebranded as Inventory Planner by Sage by 2023) and the Sage Copilot description are confirmed via vendor and press sources. No government statistical series (BLS, FRED, Census, SEC) applied to this pricing topic. Competitor prices (Prediko, Cogsy, Forthcast, Fabrikator, Cin7) are drawn from each vendor's published pages and the Prediko and Forthcast comparison posts; verify current pricing before relying on any single figure, as inventory-tool pricing changes frequently.
