Parwise vs Forstock (2026)

Short answer: Both apps do the core Stocky job (reorder points, safety stock, and purchase orders for Shopify). They differ on two things that actually matter. Pricing model: Parwise is flat ($0 / $39 / $79, never tied to your revenue, and reorder points are on the free tier), while Forstock is revenue-banded ($39 up to ~$250K, $79 up to ~$1M, $159 up to ~$5M) with no permanent free plan. Forecasting: Parwise shows you transparent velocity math you can edit; Forstock uses AI demand forecasting that factors in trend and seasonality. Pick Parwise if you want a predictable bill and math you can see; pick Forstock if AI forecasting is worth a price that grows with your store. Details and the cost math below.

What they have in common

It's a genuinely close call on the basics, so start with the overlap. Both are independent Shopify apps built for the post-Stocky world, and both give you:

• Reorder points and safety-stock planning: a per-SKU level that tells you when to restock.
• Purchase orders you can create, send, and track through receiving.
• Suppliers and lead times as first-class inputs.
• A focus on the small-to-mid Shopify store that found the $200/mo demand-planning platforms (Inventory Planner, Cogsy) far more than it needed.

If all you compare is the feature checklist, they look interchangeable. They aren't. The difference is in how they price and how they forecast.

The core difference #1: how each one prices

This is the big one, and it's the question merchants keep raising: "apps look reasonable until you realize they scale by orders or locations, then suddenly you're in ERP pricing territory."

• Parwise is flat. You pick a tier for the features you want, and the price stays put as you grow. Reorder points are free, on the free tier alongside low-stock alerts and an on-hand dashboard. If you want purchase orders and a receiving lifecycle, that's a flat $39. Never any revenue penalty.
• Forstock is revenue-banded. The entry price is $39, but it's tied to annual revenue: cross roughly $250K and you step to $79; cross ~$1M and you step to $159. The features are the same across bands. You're paying more because you grew, not because you unlocked anything new. Forstock has a 14-day trial but no permanent free plan.

Neither model is wrong. Revenue-banding lets a vendor charge a tiny shop little and a big one more, which is fair in principle, and it's the standard model for AI-forecasting tools. The thing to know is what it feels like as you grow: a tool that cost $39 when you adopted it becomes $79, then $159, for the same job, whereas a flat plan is a number you can put in a budget and forget.

The core difference #2: transparent math vs AI forecasting

The other real difference is how each decides when and how much.

• Parwise shows the math. Its reorder point is plain velocity: average daily sales (trailing 30 days) × lead time + safety stock. It's displayed, not hidden, and you can override any SKU you disagree with. The trade-off, stated honestly: it's a trailing average, so it won't anticipate a holiday spike on its own. You'd raise that reorder point by hand going into a known peak.
• Forstock uses AI demand forecasting. Its pitch is an AI model that factors in trend and seasonality to predict demand. When your sales have real seasonal shape, a good forecast can beat a flat trailing average. That's a legitimate reason to choose it.

So this isn't "transparent good, AI bad." It's a real choice: see-and-edit-it simplicity versus a model that tries to predict the curve. Against the common "most apps just mention AI a bunch of times" fatigue, some merchants specifically want math they can audit; others want the forecast to do more of the thinking. Both are valid.

Side-by-side

Verified against the Shopify App Store on June 20, 2026. Re-check both listings before relying on specific numbers, since pricing moves.

Two honest reads of that table. At a flat $39, Forstock's Starter band bundles AI forecasting you won't get on Parwise, and it has a genuine track record while Parwise is the newer listing. Where Parwise pulls ahead: reorder points are free (Forstock has no tier below $39, no permanent free plan), and the price doesn't climb with your revenue no matter how much you grow.

The math: what each costs as you grow

Say you want reorder points and purchase orders, and you track one store across three sizes.

• At $200K/year: Forstock Starter is $39/mo. If you only want the reorder decision (not POs), Parwise is $0 (free). Forstock has no tier below $39 and no permanent free plan. If you want purchase orders too, Parwise Pro is $39/mo, a tie on price for that feature set, and Forstock does throw in AI forecasting at this level.
• At $1.2M/year: you've crossed Forstock's $1M band, so it's now $159/mo (Scale). Parwise is still $0 for reorder points or $39 with purchase orders, flat. On reorder alone, that's a $159/mo gap, or nearly $1,900 a year.
• At $3M/year: Forstock stays $159/mo; Parwise is $39 (Pro) or $79 if you add supplier-feed automation and multi-location (Scale). The gap stays wide.

The pattern is consistent: at the entry level, Forstock's $39 includes AI forecasting that Parwise's free tier doesn't, so if you're under $250K and want the forecast, that's a genuine trade-off worth making. Above that, the flat plan's advantage grows with every dollar you earn, because one price is pinned to features and the other to your revenue.

When Forstock is the better choice

Said plainly, because pre-empting the objection is the honest thing to do, and there are real cases where Forstock is the right buy:

• Your sales are strongly seasonal or trending, and an AI forecast that anticipates the curve is worth paying for. Parwise's trailing velocity needs a manual nudge ahead of a known peak; a forecasting model is built for exactly that.
• You're under ~$250K in revenue and want forecasting in the entry tier. At $39, Forstock's Starter band includes the AI layer.
• You want a track record today. Forstock is already live with a 5.0-star rating (a small number of reviews so far); a brand-new listing, including Parwise's, has yet to accumulate that social proof.

One merchant in an r/shopify thread put it simply: "Forstock. Already made the switch... haven't had any stockouts since." That's real traction, and it's fair to weigh it.

When Parwise is the better choice

• You want a predictable bill that doesn't grow with your revenue. Flat $0 / $39 / $79: the price you see is the price as you scale. For a store crossing $1M, that's the difference between $0 or $39 and $159 a month.
• Reorder points cost you nothing. Parwise's free tier covers low-stock alerts, the on-hand dashboard, and reorder points with no order cap. You can get the everyday "when and how much" decision for free and only pay when you want purchase orders.
• You want math you can see and override: average daily sales × lead time + safety stock, shown per SKU, lead time and safety stock editable per SKU or store-wide. Not a forecast you have to take on trust.
• You care about data minimalism. Parwise reads orders for SKU, quantity, and cost only. It never reads or stores customer names, emails, or addresses.

Where Parwise fits

If you're leaving Stocky and your sales are reasonably steady, Parwise gives you the everyday reorder decision for free and purchase orders for a flat $39. If your business lives on forecast accuracy through strong seasonal swings, Forstock's AI forecasting is a fair reason to pay a revenue-banded price. Both replace what Stocky did; the right pick comes down to free-and-transparent versus AI-forecast-and-revenue-scaled.
