4 Best AI Tools for Shopify Wholesale & B2B in 2026

Shopify's wholesale story changed materially in April 2026: native B2B features — company accounts, custom pricing, net payment terms — used to require a Shopify Plus contract starting around $2,300 a month. They're now included on every plan, Basic included, at $39/month. That doesn't make third-party apps obsolete; it changes what they need to justify. The tools worth paying for now are the ones adding something native B2B doesn't do — AI-driven upsells, buyer-facing order automation, pricing flexibility beyond the native catalog limit — rather than the basic mechanics you now get for free. Here's how they compare.
Quick comparison
| Tool | Best for | Starting price | What it adds over native B2B |
|---|---|---|---|
| Shopify B2B (native) | Core wholesale mechanics | Included on all plans (Basic $39/mo+) | Company accounts, 3 catalogs, net terms, volume discounts |
| PortalSphere | AI-driven wholesale upsells | ~$49/mo, full feature set on every tier | AI recommendation engine for upsells/cross-sells |
| SparkLayer | Buyer-facing AI order automation | Free tier; paid from $49/mo | AI Intelligent Cart parses forwarded orders into a cart |
| Kumo | Budget custom pricing rules | $15/mo | Unlimited pricing rules by customer group, CSV import |
1. Shopify B2B (native) — the new free foundation
As of April 2026, Shopify B2B is built into every plan rather than gated behind Plus. On Basic ($39/month), Grow ($105/month), and Advanced ($399/month), you can now build up to three custom catalogs with tailored pricing, set quantity rules and volume discounts, accept net payment terms (Net 7 through Net 90, or due-on-fulfillment), vault buyer credit cards, and use the dedicated B2B trade theme — all without an extra app or a Plus contract. What's still Plus-exclusive: unlimited catalogs beyond three, direct catalog assignment to specific companies, partial payments and deposits, expansion stores for multi-region B2B, and contextual checkout customization. For a store running a single wholesale price list or a handful of customer tiers, native B2B alone now covers the job that used to require either Plus or a paid app. Shopify B2B.
Pros: genuinely free on every plan as of April 2026, covers the core mechanics most wholesale stores need, no app to install or maintain. Cons: capped at 3 catalogs outside Plus, no built-in AI recommendations or upsells, no partial payment/deposit support.
2. PortalSphere — best AI-driven upsell layer
PortalSphere's clearest differentiator is that its AI recommendation engine ships on every plan — there's no locked upper tier gating the feature that actually moves revenue. It predicts what a specific wholesale buyer is likely to add to an order based on their purchase history and surfaces those as upsells and cross-sells at the point of ordering, which matters more in B2B than retail because a single successful upsell on a bulk order is worth substantially more. Pricing starts around $49/month with a free trial, layered on top of whatever native Shopify B2B or your own custom pricing setup already handles. For a store that has the mechanics covered and specifically wants to lift average order value on wholesale orders, PortalSphere is built for exactly that gap. Try PortalSphere.
Pros: AI upsell engine included on every plan, no feature gating between tiers, built specifically for wholesale order patterns rather than adapted from retail. Cons: adds a recurring cost on top of native B2B, which is now free — worth it only if the upsell lift outweighs the subscription; newer entrant with a shorter track record than SparkLayer.
3. SparkLayer — best for buyer-facing AI order automation
SparkLayer's most distinctive feature is its AI Intelligent Cart: a wholesale buyer forwards an order email, uploads a PDF, or drops in a spreadsheet, and SparkLayer parses it into a cart automatically, matching line items against your catalog — removing the manual re-entry that both sides normally do when a buyer orders the way they've always ordered, by document rather than by browsing your site. A free plan covers up to 3 price lists and 5 orders a month; paid plans run Starter at $49/month (50 orders), Growth at $149/month (100 orders), Pro at $299/month (150 orders), and Enterprise from $499/month with unlimited orders on a custom contract. For a store whose wholesale buyers are used to ordering by document rather than through a storefront, SparkLayer's cart automation meets them where they already work. Try SparkLayer.
Pros: AI Intelligent Cart genuinely reduces manual order entry for document-based buyers, free tier to test before committing, established track record in this specific category. Cons: paid plans carry hard monthly order caps rather than unlimited orders until Enterprise, which is a real ceiling for a fast-growing wholesale channel.
4. Kumo — best budget option for pricing-rule flexibility
Kumo is the simplest and cheapest tool in this list, starting at $15/month, built around one job: letting you set unlimited custom pricing rules by customer group, with CSV import/export for managing price lists at scale and no requirement to be on Shopify Plus. Its Advanced plan runs $49/month and adds tax controls, order limits, wholesale shipping rates, quantity increments, fees, and net terms — largely overlapping with what native Shopify B2B now includes for free, which narrows Kumo's case mainly to stores that want pricing-rule flexibility beyond the native 3-catalog limit without paying for AI features they don't need. For a store on a tight budget that specifically needs more pricing-rule granularity than native B2B's catalog limit allows, Kumo fills that gap cheaply. Try Kumo.
Pros: lowest price point in this list by a wide margin, unlimited pricing rules regardless of tier, works without Shopify Plus. Cons: significant feature overlap with what native B2B now offers for free, narrowing its case since April 2026; no AI recommendation or upsell layer.
How to choose
- You're launching your first wholesale price list and don't need anything fancy: start with native Shopify B2B — it's free on your existing plan.
- You want AI upsells lifting your average wholesale order value: add PortalSphere on top.
- Your buyers order by forwarding a PDF or spreadsheet instead of browsing your storefront: SparkLayer's AI cart meets them there.
- You need more pricing-rule flexibility than 3 catalogs but don't want to pay for AI features: Kumo.
The honest verdict: try native Shopify B2B first — the April 2026 change to make it free on every plan means most stores no longer need to pay anything just for the mechanics. Layer on PortalSphere or SparkLayer only once you've identified a specific gap native B2B doesn't fill, whether that's AI-driven upsells or automating how document-based buyers place orders. If you're setting up the storefront itself before worrying about wholesale specifically, our best AI tools to build a Shopify store guide covers that groundwork, and our best AI tools for Shopify upsell and cross-sell roundup covers the retail side of the same AI-upsell logic PortalSphere applies to wholesale.

Frequently asked questions
Do I still need Shopify Plus to run a B2B wholesale storefront?
No, not for the core features. As of April 2026, Shopify made native B2B — company accounts, up to 3 custom catalogs, net payment terms, quantity rules and volume discounts, and the dedicated B2B trade theme — available on Basic, Grow, and Advanced plans at no extra cost. Plus is still required for unlimited catalogs, partial payments and deposits, expansion stores, and contextual checkout customization, so large or complex B2B operations may still need it — but a straightforward wholesale storefront no longer does.
What does an AI upsell engine actually add on top of native Shopify B2B?
Native Shopify B2B handles the mechanics — custom pricing, net terms, catalogs — but doesn't recommend products. Apps like PortalSphere layer an AI recommendation engine on top that predicts what a specific wholesale buyer is likely to reorder or add to a bulk order, surfacing those as upsells at checkout. It's the same logic as retail cross-sell tools, applied to B2B order sizes where a single successful upsell is worth far more per order.
What is an 'AI Intelligent Cart' and why would a wholesale buyer want one?
It's a feature (SparkLayer's implementation is the most established) where a buyer forwards an order email, PDF, or spreadsheet and the app parses it into a shopping cart automatically, matching line items to your catalog. Many wholesale buyers still order via a purchase order document out of habit — this removes the manual re-entry step on both sides without forcing the buyer to change how they work.
Should I use a dedicated app if Shopify B2B is now free on my plan?
It depends on what you need beyond the mechanics. Native Shopify B2B covers pricing, catalogs, and payment terms well. A dedicated app is worth the added monthly cost specifically when you want AI-driven upsells (PortalSphere), a buyer-facing AI cart that parses uploaded orders (SparkLayer), or pricing-rule flexibility beyond the 3-catalog limit on non-Plus plans (Kumo). If you just need the core mechanics, native B2B alone may be enough.
