Inventory Planner vs Cogsy in 2026: which demand-forecasting tool earns its keep at your revenue band

Disclosure: Eightx engages clients on both platforms. No vendor sponsorship for this post.

If you are running a Shopify DTC brand and weighing demand-planning software, the Inventory Planner vs Cogsy question gets framed online as a feature shootout. It is not. The right answer depends on your revenue band, your SKU count, and how much of your revenue runs through channels and warehouses Shopify does not own. We help brands at $5M, $15M, and $30M make this call several times a quarter. The crossover is consistent, the math is consistent, and the trap is the same: operators picking on UI rather than on where their business will be in 18 months.

The decision is not features, it is revenue band plus channel mix

Both tools forecast demand, surface reorder points, automate purchase orders, and integrate with Shopify. The reason one wins over the other in a specific brand is rarely about a missing feature. It is about who the tool was built for.

Cogsy was built for Shopify-first DTC brands running launches, promos, and pre-orders, with a founder or ops lead driving the inputs. The UI is opinionated, the pricing is flat (you know what you are paying), and the implementation runs in days, not weeks. Inventory Planner was built for multi-channel brands with at least one warehouse or 3PL, real PO volume, and a planner or buyer on staff. The UI surfaces more knobs, the pricing scales with your revenue and complexity, and the implementation runs in weeks.

That framing carries the rest of the post. If your revenue is under $10M and your stack is Shopify with a light Amazon connection, Cogsy wins almost every time on total cost of ownership. If you are above $10-15M with Amazon, wholesale, a 3PL, or more than one warehouse, Inventory Planner's depth on POs, suppliers, and multi-location forecasting earns the higher sticker. The crossover band is where a feature-by-feature comparison matters; outside it, the channel mix decides for you.

Cogsy: where it wins

Cogsy's pitch is simple: Shopify-native demand planning, $199 per month, 14-day free trial, set up in a day. The Shopify App Store listing confirms the $199 entry plan with all features included, and cogsy.com/pricing carries the same number. There are no surprise add-ons for the entry band.

The places Cogsy is hard to beat: a Shopify DTC brand at $1-10M with under 1,000 active SKUs (the documented threshold where operators we work with start looking elsewhere), monthly or quarterly product drops, and a founder or ops lead doing the planning. Cogsy's launch and promo logic was designed for that workflow. It handles pre-orders cleanly, surfaces stockout risk by SKU and variant, and triggers POs with enough lead-time logic to keep peak demand in stock. For brands that grew up on Stocky, the UI muscle memory transfers in an afternoon.

Where Cogsy starts to strain: above $10M with Amazon as a real channel, more than one warehouse, or wholesale orders that need separate allocation logic. The product supports those use cases, but it was not built for them in the way Inventory Planner was. Founders we work with describe this as a feel-of-the-tool problem more than a specific missing feature.

Inventory Planner by Sage: where it earns the price tag

Inventory Planner's public floor is $249.99 per month on BigCommerce's app marketplace, and the listing explicitly notes pricing is "based on your annual revenue." Recent 2026 reviews (revenuegeeks.com, getply.com) report quote-based pricing scaling to $10,000+ per year for $10M+ brands and into low five figures annually for $20M+ brands. The product was acquired by Sage Group in 2022 and now sells under the "Inventory Planner by Sage" brand across every distribution surface.

What the higher price buys you: native integrations to Shopify, Amazon, BigCommerce, WooCommerce, Walmart, eBay, plus QuickBooks Online and Excel. Strong multi-warehouse forecasting with per-location reorder points. Deep PO automation that handles supplier MOQs, payment terms, and multi-PO scenarios. The kind of depth a planner or buyer needs to drive a $15-50M operation without falling back to a spreadsheet for the edge cases.

The Capterra rating sits at 4.4/5 across 65 reviews with 94% positive sentiment. The most common praise is forecast accuracy and PO automation. The most common criticism is pricing opacity at scale, which is the trade-off you sign up for when you move from a flat-tier SaaS to a revenue-based enterprise model.

The chart above shows how the fit shifts. At $1-10M Shopify-first, Cogsy scores 5 of 5 and Inventory Planner scores 2-3. At $10-20M with Amazon plus a single warehouse, both score 4 of 5 (this is the crossover band where the decision is genuinely contested). Above that, with multi-warehouse, wholesale, or pre-PE-diligence complexity, Inventory Planner scores 5 of 5 and Cogsy drops to 1-2.

The working-capital math: why either tool pays for itself

The Shopify and BigCommerce 2026 inventory-management guides both cite 15-25% reduction in average inventory on hand as a typical outcome when a brand moves from Stocky or spreadsheets to a real demand planner. The mechanism is the same for both tools: better forecasts let you carry less safety stock without taking stockout risk, and PO automation catches reorder points you would otherwise miss.

We model this assuming COGS is 40% of revenue and a pre-optimization inventory position of 4 months of supply on hand. These are directional assumptions, not universal: 40% COGS is closer to premium DTC apparel and beauty than to food, CPG, or supplements where COGS runs higher, and 4 months on hand is the lower end of where brands typically realize they have a problem (many sit at 5-6+ months when the conversation starts). The chart and numbers below scale linearly with both inputs.

At $5M revenue, a 15% reduction frees $100K and a 25% reduction frees $167K. At $10M, the range is $200K to $333K. At $30M, it is $600K to $1M. At $50M, it is $1M to $1.67M. Cogsy at $199 per month costs about $2,400 per year. Inventory Planner at $10K+ per year for a $20M brand costs more. In both cases, the cash freed in year one is two to three orders of magnitude larger than the subscription. The tool is not the expensive line item; the inventory you are carrying is.

This is also why the "should we just stay on Stocky" conversation usually ends quickly when we lay out the numbers with a founder. The downside of paying for the wrong tool is a few thousand dollars. The downside of running a $15M brand on spreadsheets is hundreds of thousands of dollars sitting in a 3PL.

The crossover signals: when you have outgrown Cogsy

The crossover is not a hard revenue number. It is a set of signals. Once two or three of these show up together, Inventory Planner usually starts to make sense.

Signal	Threshold to watch	Tool implication
SKU or variant count	1,000+ active SKUs or complex size curves	Inventory Planner
Warehouse or 3PL nodes	2+ locations needing per-location forecasts	Inventory Planner
Channel mix	Amazon, Walmart, or wholesale over 20% of revenue	Inventory Planner
Annual PO spend	$2-3M+ with dozens of POs per month	Inventory Planner
Supplier complexity	MOQ, multi-currency, multi-payment-term	Inventory Planner
Lead-time variance	60-120 day lead times with seasonality	Inventory Planner
ERP roadmap	NetSuite implementation in 12-24 months	Inventory Planner (or ERP-native)
Below all of the above	Single warehouse plus Shopify-first DTC	Cogsy

The Inventory Planner vs Cogsy debate is not really about features. Cogsy wins under $10M Shopify-first because it was built for that operator. Inventory Planner wins above $10M with channel and warehouse complexity because that is who it was built for. The tool decides itself once you list your SKUs, your locations, and your channel mix on a single page.

What we would actually do in your seat

If you are under $5M with a single warehouse and Shopify is your only meaningful channel, stay on Stocky and a tight spreadsheet for another quarter. The tool is not the constraint at that scale; your forecast inputs and reorder discipline are.

If you are $5-15M Shopify-first with Amazon as a secondary channel, run the Cogsy 14-day free trial and decide on day 10. The implementation is short enough that you can have it forecasting your fall buy by the time the trial closes. Plan for roughly $2,400 per year in tool cost (the $199 monthly floor annualized) and, in our experience, a quarter or two before the working-capital reduction shows up cleanly in the cash position.

If you are $15M+ with Amazon as a primary channel, wholesale orders, multiple warehouses, or a NetSuite implementation on the roadmap, start the Inventory Planner conversation. Get two quotes (one from Inventory Planner direct, one from a Sage reseller if applicable), and bring your SKU count, location count, and annual PO volume to the call. Public secondary reporting puts pricing at $10K+ per year at scale and low five figures annually for $20M+ brands (directional, vendor quotes vary). The two-week implementation buys you the multi-channel forecasting that Cogsy cannot match at this scale.

If you are mid-crossover (around $10-12M with mixed signals), pilot Cogsy first. Migration from Cogsy to Inventory Planner is straightforward if you outgrow it; over-buying the tool you do not yet need is a worse mistake than under-buying the one you can replace in 18 months.

A side note worth mentioning: this is not a two-tool universe. Netstock, Prediko, Forthcast, Fabrikator, and StockDesk all show up in the 2026 buyer's-guide comparison set. They serve narrower segments (Netstock for distributors, Prediko for fast-fashion, Fabrikator for emerging Shopify brands) and are worth a 30-minute look if your business does not fit cleanly into either Cogsy or Inventory Planner. But for the canonical DTC Shopify brand at $5-50M with Amazon and one or two warehouses, the binary is real.

Sources and methodology

We pulled the public pricing floors directly from the vendor distribution surfaces on 2026-06-02. Cogsy's $199 per month appears on cogsy.com/pricing and the Shopify App Store. Inventory Planner's $249.99 per month appears on BigCommerce's app marketplace listing, which is the most explicit public floor the vendor publishes. Pricing above the floor is quote-based and we did not get net-net pricing data from either vendor for this post; the "$10K+ per year at scale" figure is sourced from secondary reporting (revenuegeeks.com, getply.com) and should be treated as directional.

The Capterra rating for Inventory Planner (4.4/5 across 65 reviews, 94% positive sentiment) was pulled from capterra.com/p/151776/Inventory-Planner/. We did not surface a clean consolidated G2 star rating for Cogsy in the 2026 search snippets, so we omitted a Cogsy social-proof number rather than quote a stale one. Operators evaluating Cogsy should check the live G2 page at publish time.

The Sage acquisition is confirmed by the "Inventory Planner by Sage" branding across the Shopify App Store, G2, Capterra, and LinkedIn. Secondary sources date the acquisition to 2022. We did not confirm the exact month against a Sage press release for this post; the writer should verify before stating a specific date in any future refresh.

The working-capital math (15-25% inventory reduction) is sourced from Shopify's overstocking guide and BigCommerce's 2026 inventory-management article. The dollar figures assume COGS is 40% of revenue and a starting position of 4 months of inventory on hand, which is a directional DTC assumption (premium apparel and beauty trend lower on COGS, food and supplements trend higher). These are not vendor-guaranteed outcomes.

Operator observations in this post ("founders we work with describe this as a feel-of-the-tool problem," "operators we work with do not report a product-quality drop") are triangulated from our internal founder-call library across the DTC brands Eightx engages at $5-50M GMV. No client names disclosed.

This page is part of our Group A living-index series. We refresh it quarterly: pricing floors, ratings, ownership status, and the integration list are the fields most likely to shift between refreshes. The next refresh target is September 2026.

Frequently asked questions

is cogsy cheaper than inventory planner for a $5m shopify brand?

Yes, materially. Cogsy publishes a $199 per month floor on its pricing page and the Shopify App Store. Inventory Planner's public floor is $249.99 per month on BigCommerce, and the revenue-based scaling pushes a $5M brand toward the higher end of the entry band. For Shopify-only DTC at $5M, Cogsy wins on sticker and on setup time.

did sage actually buy inventory planner and does it still feel like the same product?

Yes, Sage acquired Inventory Planner in 2022, and the product is now branded "Inventory Planner by Sage" across the Shopify App Store, G2, and Capterra. The core forecasting and PO logic stayed intact. The commercial side feels more enterprise (longer sales cycles, quote-based pricing above the floor) but operators we work with do not report a product-quality drop.

does cogsy work for amazon or is it shopify only?

Cogsy supports Amazon, but it is lighter than Inventory Planner's Amazon integration. If Amazon is 10-20% of revenue and operationally simple, Cogsy handles it. If Amazon is a primary channel with FBA replenishment, multi-marketplace SKUs, and Vendor Central exposure, Inventory Planner's deeper Amazon support is worth the price difference.

when should i stop using stocky and pay for inventory planner or cogsy?

When you start losing money in two places at once: stockouts on launches plus overstock on aged SKUs. Practically, that hits most brands between $3-5M revenue. The trigger is not revenue, it is whether you can still hold the forecast in your head. Once you cannot, the planner pays for itself fast through inventory reduction alone; time-to-impact depends on how aged your current stock position is.

how much cash can i actually free up by switching from spreadsheets to a planner?

Shopify and BigCommerce 2026 guidance puts the range at 15-25% reduction in average inventory on hand. At $10M revenue with 40% COGS and 4 months of supply, that is $200K-$333K of cash freed up. At $30M it is $600K-$1M. Neither vendor publishes a guaranteed outcome, but the directional math is consistent across the operators we work with.

does inventory planner integrate with netsuite out of the box?

No. Neither Inventory Planner nor Cogsy has a documented native NetSuite connector in 2026. Both rely on middleware (Celigo, Patchworks) for the NetSuite handshake. If NetSuite is on your 12-24 month roadmap, factor in the middleware cost and timeline before you sign either contract.

can either of these handle pre-orders and launches for a dtc brand?

Both do. Cogsy was built around the DTC launch loop and handles pre-orders, drops, and promo-driven demand spikes with less configuration. Inventory Planner handles the same flows but assumes you have a planner or buyer driving the inputs. For a founder-led DTC brand running monthly drops, Cogsy is the lower-friction choice.

what happens to inventory planner pricing once i cross $10m in revenue?

It moves to a quote-based conversation. Public secondary reporting (revenuegeeks.com, getply.com) cites $10K+ per year at scale, with low five figures annually for $20M+ brands. Vendor reps will negotiate. Bring your SKU count, location count, and PO volume to the call, and in our experience there is usually room to negotiate the first quote if you push on contract length or annual prepay.
