Assisty vs. Supremo
Assisty is a tiered AI/ML forecasting and replenishment app for Shopify, where advanced features unlock as you move up four pricing tiers. Supremo is a transparent, formula-based reorder point and purchase order app where every feature is included on every plan, priced only by product count.
Both apps offer a permanently free plan, but what's actually included in "free" differs sharply. This comparison covers pricing, every major feature dimension, six real merchant scenarios, a migration path, and 21 frequently asked questions — using publicly listed data from the Shopify App Store and each vendor's own pricing pages, verified July 2026.
Quick answer
Choose Assisty if you want AI/ML-driven demand forecasting, a dynamic replenishment engine, or an advanced buying calendar — especially on Shopify Plus, where its $239/month Enterprise tier unlocks the full feature set. Choose Supremo if you want a transparent, auditable reorder formula and a complete purchase order and vendor workflow on every plan, including a genuinely full-featured Free tier under 100 products.
Who Should Choose Each
Choose Assisty if...
- You want AI/ML demand forecasting and are willing to pay for the Enterprise tier

- You want a dynamic replenishment engine layered on top of your sales data
- You want unlimited custom reports and hourly data updates on a mid-tier plan
- You're comfortable choosing among four pricing tiers to reach full functionality
Choose Supremo if...
- You want your free plan to include real purchase order and reorder automation, not just reports
- You want to see the exact formula behind every reorder point, not a black-box AI score
- You need cycle counts and stocktake tools alongside purchasing
- You want multi-location tracking without upgrading to a $39+/month tier

Detailed Feature Analysis
Forecasting & reorder logic
Assisty: Offers AI/ML-driven demand forecasting, but only on its Enterprise tier ($239/month, Shopify Plus). Lower tiers provide reporting, dashboards, and — from Professional upward — a "dynamic replenishment engine," which sits between basic reporting and full machine-learning forecasting. As with most ML tools, the exact model weighting isn't published to merchants as a formula.
Supremo: Calculates a reorder point per SKU using a published formula: sales velocity x lead time + safety stock buffer, based on actual Shopify order history, recalculated hourly, on every plan including Free. There's no machine learning layer and no tier to unlock it — every number can be traced back to the inputs that produced it.
Purchase orders & receiving
Based on Assisty's published plan comparison, a full purchase order creation, sending, and receiving workflow sits in its Enterprise tier ($239/month). Supremo includes full PO lifecycle management — create, assign to a vendor, send as PDF by email, mark received in full or partially, close, cancel, duplicate, or export to CSV — on every plan, including Free.
Free-tier depth
This is the sharpest difference between the two apps. Assisty's Free plan (6 months of data, 3 custom reports, 1 dashboard) is a reporting and visibility tool, not a replenishment tool — there's no reorder automation or purchase order workflow until at least the Basic tier ($19/month), and full functionality requires much higher tiers. Supremo's Free plan is feature-complete: the same reorder formula, PO workflow, vendor management, and stocktakes available on the $99/month Scale plan, just capped at 100 products and 2,000 variants.
Supplier / vendor management
Supremo lets you maintain a full supplier list with contact details and lead times, and assign multiple vendors to a single product with individual lead times per vendor, feeding directly into that product's reorder point calculation. Assisty's public plan comparison does not detail per-vendor lead time management as a distinct, granular field the way Supremo does; its supplier workflow is bundled into the broader Enterprise-tier PO and receiving feature.
Dynamic replenishment engine
Assisty markets a "dynamic replenishment engine" starting at its Professional tier ($39–99/month depending on Shopify plan), positioned as more adaptive than a fixed formula. Supremo doesn't use this specific term; its equivalent is the transparent reorder point formula, recalculated hourly from live order data on every plan — always current, but rules-based rather than adaptive in the machine-learning sense.
Multi-location support
Supremo tracks inventory levels and reorder points across every Shopify location on every plan, including Free, and supports tracked transfer orders between locations. Assisty lists multi-location tracking as a Professional-tier feature and above, meaning stores on its Free or Basic plans do not get this functionality without upgrading to at least $39/month.
Reporting & data history
Assisty's Free plan includes 3 custom reports and 6 months of historical data; Basic and above unlock full history, hourly data updates, and unlimited custom reports. Supremo ships with 8 standard, CSV-downloadable reports — Inventory Valuation, Dead Stock, ABC Analysis, Stock Movement, Vendor Performance, Purchase Order History, Reorder Analysis, and Stocktake Variance — covering full Shopify order history, on every plan.
Data export & spreadsheet tools
Assisty adds data export starting at its Basic tier ($19/month), and spreadsheet integration specifically at Enterprise ($239/month). Supremo includes CSV export for every report on every plan, including Free, without a spreadsheet-integration layer beyond that.
Ease of use & onboarding
Supremo is built for self-serve setup: install, and reorder points start calculating immediately from existing Shopify order history, with no tier decision required to get core functionality working. Assisty requires selecting among four pricing tiers to determine which features you get, and its more advanced tools (dynamic replenishment, AI/ML forecasting, buying calendar) require more configuration, particularly at the Enterprise tier.
Customer support
Both vendors offer support through the Shopify App Store's standard review and messaging channels. Assisty's higher tiers, particularly Enterprise, are more likely to involve support contact for configuring AI/ML forecasting and buying calendar setup correctly. Supremo's simpler, flat feature set means most support questions are answerable directly from in-app help text and documentation.
Scalability
Assisty's pricing scales with feature tier and, for Professional, with the merchant's underlying Shopify plan — meaning two stores with the same catalog size can pay different amounts depending on which Shopify plan they're on. Supremo's pricing scales purely with product and variant count, regardless of Shopify plan level, which makes cost more predictable as a catalog grows but doesn't offer a path to machine-learning forecasting at any price point.
Shopify integration depth
Both apps embed directly in the Shopify admin and read from Shopify's native product, variant, and order data rather than requiring a separate product catalog. Supremo additionally writes stocktake adjustments directly back into Shopify's inventory levels, keeping Shopify as the single source of truth for on-hand quantities. Assisty's forecasting and replenishment layers read from the same underlying Shopify data to generate their reports and recommendations.
Merchant Scenarios
Six real-world Shopify merchant profiles and which app fits better, based on the feature differences above.
New Shopify store, under 50 products
Better fit: SupremoA brand-new store with a small catalog gets more functional value from Supremo's Free plan, which includes full reorder point calculation, purchase orders, and vendor management at zero cost. Assisty's Free plan at this stage is limited to 3 reports and a single dashboard — useful for visibility, but without the replenishment automation this merchant likely wants at launch.
Shopify Plus brand wanting AI/ML forecasting and a buying calendar
Better fit: AssistyThis is exactly the use case Assisty's Enterprise tier ($239/month) is built for: AI/ML-driven demand forecasting, an advanced buying table and calendar, and spreadsheet integration, all suited to Plus-level operational complexity. Supremo has no equivalent ML forecasting layer or buying calendar, making Assisty the stronger fit here.
Budget-conscious multi-location retailer, 3 Shopify locations
Better fit: SupremoSupremo includes multi-location tracking and stock transfers on every plan, including Free (under 100 products) or Starter ($19/mo up to 500 products). Assisty gates multi-location tracking behind its Professional tier, which costs $39–99/month depending on the merchant's Shopify plan — a materially higher cost for the same core capability.
Seasonal business needing accurate safety stock buffers
Better fit: Depends on budgetA seasonal brand benefits from Supremo's transparent formula, where the safety stock buffer is an explicit, adjustable input the merchant controls per SKU going into each season. Assisty's lower tiers don't include forecasting at all, and its AI/ML forecasting only appears at the $239/month Enterprise tier, which may be worth it if the brand specifically wants a model to learn seasonal patterns automatically rather than set safety stock manually.
Growing brand that outgrew basic sales reporting
Better fit: SupremoA brand that started on either app's free tier and now wants real replenishment automation faces a similar decision: Assisty's next step up (Basic, $19/mo) still doesn't include full PO automation or multi-location tracking — those require Professional ($39–99/mo) or higher. Supremo's next step up (Starter, $19/mo) includes every feature Supremo offers, just at a higher product/variant ceiling, making the upgrade path simpler to reason about.
Cost-sensitive startup wanting to test AI forecasting before committing
Better fit: AssistyAssisty offers a 14-day free trial on its paid tiers, letting a startup test AI/ML forecasting risk-free before paying. Supremo doesn't offer AI forecasting at any tier, so a merchant whose primary goal is evaluating machine-learning demand prediction should trial Assisty directly; a merchant who decides they don't need ML forecasting can fall back to Supremo's permanently free plan afterward.
Pros & Cons
Assisty
Pros
- • AI/ML demand forecasting available at the top tier
- • Dynamic replenishment engine on Professional and above
- • Advanced buying table & calendar for Shopify Plus (Enterprise)
- • 14-day free trial on every paid tier
- • 4.8-star rating from 345 reviews (July 2026)
Cons
- • Free plan is reporting-only; no reorder or PO automation
- • Full PO & receiving workflow gated behind the $239/mo Enterprise tier
- • Multi-location tracking requires at least the Professional tier
- • Professional-tier pricing varies by Shopify plan, adding complexity
Supremo
Pros
- • Free plan includes every feature, not just reporting
- • Transparent, auditable reorder point formula on every plan
- • Full PO, vendor, and multi-location workflow at every tier
- • One flat price per catalog size, regardless of Shopify plan level
- • Cycle counts and stocktakes included on every plan
Cons
- • No AI/ML demand forecasting at any price point

Neither list of cons is a dealbreaker in isolation — they reflect different product philosophies rather than execution gaps. Assisty's cons matter most to merchants who want full functionality without climbing through four pricing tiers or without a Shopify Plus budget. Supremo's cons matter most to merchants who specifically want machine-learning-driven forecasting or an advanced buying calendar and are prepared to pay for it.
Migrating From Assisty to Supremo
Because Assisty's reporting and forecasting sit on top of Shopify's own product and inventory data rather than owning that data exclusively, switching apps doesn't put your core inventory at risk. On install, Supremo automatically imports your current Shopify catalog: products, variants, vendors, inventory levels, and order history — the same import behavior used for any new installation, documented in Shopify's own inventory management guidance.
What does not carry over automatically is Assisty-specific configuration: saved custom reports, any buying calendar setup, and forecast history. If you rely on any of these, export or document them from Assisty before switching, since they're specific to Assisty's platform rather than to Shopify's underlying inventory records. As noted above, do not assume supplier records will migrate automatically from either app — verify and, if needed, manually re-enter vendor details regardless of which system you move to or from.
- Export any Assisty-specific reports, saved forecasts, or buying calendar data you want to keep for reference.
- Install Supremo; it imports your live Shopify catalog, vendors, and inventory levels automatically.
- Re-enter per-vendor lead times if you want Supremo's reorder point formula to reflect them precisely.
- Run a test purchase order and a test stocktake before fully retiring Assisty.
- Uninstall Assisty once you've confirmed reorder points and PO workflows behave as expected in Supremo.
Plan for a short overlap period rather than an instant cutover. Running both apps in parallel for one to two reorder cycles lets you compare Assisty's replenishment suggestions against Supremo's formula-based reorder points on the same SKUs, which builds confidence in the new numbers before you commit fully. This is especially worthwhile for your highest-velocity SKUs, where a reorder timing mistake has the largest revenue impact.
If you're on Assisty specifically for its AI/ML demand forecasting or advanced buying calendar, note that Supremo has no equivalent feature. In that case, either keep Assisty active for forecasting while using Supremo for the transparent reorder/PO workflow, or confirm you're comfortable moving to a formula-based system before uninstalling Assisty's Enterprise-tier tools.
Frequently Asked Questions
Is Assisty free?
Assisty has a permanently free plan, not just a trial: 6 months of historical data, 3 custom reports, and 1 dashboard, aimed at small stores. Its AI/ML demand forecasting, purchase order & receiving workflow, and dynamic replenishment engine are gated behind paid tiers starting at $19/month (Basic) and reaching $239/month (Enterprise, for Shopify Plus stores). Supremo's Free plan, by contrast, includes every feature — full reorder point calculation, purchase orders, vendor management, and stocktakes — for stores under 100 products, with no feature gating.
What is the main difference between Assisty and Supremo?
Assisty is a tiered AI/ML forecasting and replenishment platform where advanced capabilities (AI forecasting, full PO & receiving, multi-location tracking, a dynamic replenishment engine) unlock progressively as you move up four pricing tiers, topping out at $239/month for Shopify Plus stores. Supremo is a transparent, formula-based reorder point and purchase order app where every feature — including the formula itself — is available on every plan, including Free, with pricing gated only by product and variant count up to $99/month.
Does Assisty show how it calculates reorder recommendations?
Assisty's top-tier AI/ML demand forecasting (available on its $239/month Enterprise plan) is a machine-learning model; like most ML-based forecasting tools, the exact internal weighting isn't published to merchants as a formula. Supremo instead publishes the literal calculation for every SKU on every plan: reorder point = sales velocity x lead time + safety stock buffer, recalculated hourly from live Shopify order data.
What does Assisty's free plan actually include?
As of July 2026, Assisty's free plan includes 6 months of historical sales data, 3 custom reports, and 1 dashboard — useful for basic visibility into sales trends. It does not include AI forecasting, dynamic replenishment, or a full purchase order and receiving workflow; those require the Basic ($19/mo), Professional ($39–99/mo depending on Shopify plan), or Enterprise ($239/mo) tiers.
What does Supremo's free plan include?
Supremo's Free plan includes every feature the app offers — reorder point calculation, purchase order creation and tracking, vendor management, multi-location inventory, stock transfers, stocktakes, and all 8 built-in reports — for stores with up to 100 products and 2,000 variants. Nothing is held back for a paid tier; the Free plan is feature-complete, just capacity-limited.
Which app is cheaper for a small store under 100 products?
Supremo, in most cases. A store under 100 products qualifies for Supremo's fully-featured Free plan. The equivalent functionality on Assisty — AI forecasting and a full replenishment workflow — requires at least the Basic tier ($19/mo) and, for true AI/ML forecasting and PO automation, the higher Professional or Enterprise tiers ($39–239/mo). Assisty's own Free plan is more limited: reporting and dashboards only, without forecasting or PO automation.
Does Supremo do AI/ML demand forecasting like Assisty's Enterprise tier?
No. Supremo uses a transparent, rules-based reorder point formula (sales velocity x lead time + safety stock) rather than a machine-learning model. Assisty's Enterprise plan ($239/month, Shopify Plus only) includes AI/ML-driven demand forecasting, an advanced buying table and calendar, and spreadsheet integration. Merchants who specifically want machine-learning-based demand plans at that price point should evaluate Assisty's Enterprise tier directly.
At what price does Assisty include full purchase order automation?
Based on Assisty's published plan comparison, its most complete purchase order and receiving workflow, alongside an advanced buying table and calendar, sits in the Enterprise tier at $239/month (Shopify Plus stores). Lower tiers (Free, Basic, Professional) are weighted toward reporting, dashboards, and — starting at Professional — a dynamic replenishment engine and multi-location tracking, rather than a full PO lifecycle. Confirm current tier-by-tier feature gating on Assisty's own pricing page before deciding, as SaaS pricing pages change.
Does Assisty's Professional plan cost the same for every store?
No. Assisty's Professional tier is priced differently depending on the merchant's underlying Shopify plan: it runs roughly $39/month for a standard Shopify plan, $59/month for Shopify Advanced, and up to $99/month for Shopify Plus stores on that tier. This is a different pricing model than Supremo, where every plan has one fixed price regardless of which Shopify plan the merchant is on.
How many reports does each app include?
Assisty's Free plan includes 3 custom reports; paid tiers unlock unlimited custom reports starting at Basic ($19/mo). Supremo ships with 8 standard, CSV-downloadable reports — Inventory Valuation, Dead Stock, ABC Analysis, Stock Movement, Vendor Performance, Purchase Order History, Reorder Analysis, and Stocktake Variance — included on every plan, including Free.
Which app has better multi-location support?
Supremo includes multi-location inventory tracking and stock transfers on every plan, including Free. Assisty's plan comparison lists multi-location tracking starting at its Professional tier ($39–99/mo depending on Shopify plan), meaning stores on Assisty's Free or Basic plans do not get multi-location functionality without upgrading.
Can I run cycle counts or stocktakes in Assisty?
Assisty's public plan comparison does not list a dedicated stocktake or cycle-count feature with variance review across any of its tiers; its focus is reporting, forecasting, and replenishment. Supremo includes stocktakes on every plan: run a full or partial inventory count, review variance between expected and actual quantities, then apply adjustments directly back to Shopify.
What is Assisty's Shopify App Store rating?
As of July 2026, Assisty holds a 4.8-star rating from 345 reviews on the Shopify App Store, with 92% of reviews at 5 stars. It has been listed since June 2021. Ratings and review counts change over time, so check the current listing before deciding.
Does Assisty claim to auto-migrate supplier data from Stocky?
Assisty's marketing describes itself as a Stocky replacement with migration support for suppliers and purchase orders. This claim should be verified directly with Assisty before relying on it: Shopify's own Stocky documentation states that supplier records cannot be exported from Stocky to any third party in any format, which would make a fully automatic supplier migration technically difficult. Whichever app you choose, plan to manually verify and, if needed, re-enter supplier details rather than assuming an automatic migration will be complete.
Which app is easier to set up for a first-time user?
Supremo is designed for install-and-go setup: install, and reorder point calculations start immediately from existing Shopify order history, with no onboarding call required and no tier to select first. Assisty requires choosing among four pricing tiers to access its full feature set, and its more advanced forecasting and replenishment tools are more involved to configure correctly, particularly at the Enterprise tier.
Do both apps track inventory across multiple Shopify locations?
Supremo tracks inventory levels and reorder points across every Shopify location on every plan, including Free. Assisty lists multi-location tracking as a feature of its Professional tier and above ($39–99/mo depending on Shopify plan), so multi-location merchants on Assisty's Free or Basic plans would need to upgrade to get this functionality.
Is Assisty or Supremo better for a brand doing under $50,000 in annual revenue?
Supremo is generally the more cost-effective choice at this stage, since a brand this size is also likely under 100 products and qualifies for Supremo's fully-featured Free plan. Assisty's free plan is more limited (reporting only, no forecasting or PO automation), so a fast-growing small brand wanting real replenishment automation on Assisty would likely need to move to at least the $19/month Basic or $39+/month Professional tier.
How do the two apps price as a store grows?
Assisty's price increases in tiered jumps tied to feature access and, for the Professional tier, the merchant's Shopify plan level: Free, $19/mo (Basic), $39–99/mo (Professional, varies by Shopify plan), and $239/mo (Enterprise, Shopify Plus only). Supremo's price increases in steps tied purely to catalog size: Free under 100 products, $19/mo under 500 products, $49/mo under 2,000 products, and $99/mo for unlimited products, with every feature included at every tier. A merchant wanting AI/ML forecasting and a buying calendar at any cost will pay more on Assisty than Supremo ever charges; a merchant who never needs AI forecasting will likely spend less on Supremo long-term.
Can I migrate from Assisty to Supremo?
Yes. Assisty's forecasting and reporting layer sits on top of Shopify's own product and inventory data rather than owning it exclusively, so switching doesn't put your core inventory at risk. On installing Supremo, it automatically imports your current Shopify catalog, variants, vendors, and inventory levels. What doesn't carry over automatically is Assisty-specific configuration — saved forecasts, custom report definitions, and any buying calendar setup — which would need to be manually reviewed and, if needed, replicated in Supremo's simpler formula-based system or documented separately.
Which app should a Shopify Plus merchant choose?
It depends on whether the merchant specifically wants AI/ML demand forecasting and an advanced buying calendar. Assisty's Enterprise tier ($239/month) is built for exactly that use case on Shopify Plus. A Shopify Plus merchant who instead wants a transparent, auditable reorder formula with a full PO/vendor workflow at a fraction of that cost — Supremo's Scale plan is $99/month flat, regardless of Shopify plan level — may find Supremo the more cost-effective and operationally simple option even at the Plus tier.
Does either app offer a mobile app for stocktakes or receiving?
Neither Assisty's nor Supremo's public documentation currently describes a dedicated native mobile app; both are used primarily through the Shopify admin embedded interface on desktop or mobile browser. Merchants who specifically need a barcode-scanning mobile stocktake app should evaluate that requirement separately from this comparison.
Which app is better for a brand that wants a dynamic replenishment engine?
Assisty explicitly markets a dynamic replenishment engine, available from its Professional tier upward ($39–99/mo depending on Shopify plan). Supremo doesn't use that term; its equivalent is the transparent reorder point formula recalculated hourly on every plan. If "dynamic replenishment engine" specifically means an algorithmic, self-adjusting model beyond a fixed formula, Assisty's paid tiers are the closer match; if it means an always-current, automatically recalculated reorder trigger, Supremo provides that on every plan including Free.
Final Recommendation
Assisty and Supremo both start free, but "free" means very different things on each app. If you specifically want AI/ML demand forecasting, a dynamic replenishment engine, or an advanced buying calendar — particularly on Shopify Plus — Assisty's paid tiers, up to $239/month, are built for that. If you want a fully-featured free plan, a transparent and auditable reorder calculation, and a complete purchase order and vendor workflow without climbing through pricing tiers, Supremo is the more cost-effective and operationally simple choice.
The lowest-risk way to decide is to try both. Assisty offers a 14-day free trial on its paid tiers, and Supremo's Free plan has no time limit for stores under 100 products, so you can run Supremo at zero cost indefinitely while trialing Assisty's higher tiers in parallel to compare forecast quality and replenishment fit against your own sales data before committing to a paid subscription.
