Magento for B2B Wholesale

Both reach roughly the same destination, the path is different.

Adobe Commerce B2B (native): ships a Companies module with a parent → child → buyer hierarchy, role-based purchase thresholds (e.g. Buyer can place orders up to $5k, Approver up to $50k, Company Admin unlimited), and an approval workflow that routes a pending order through the right approver before it’s placed. Cost: rolled into the Adobe Commerce license at $30k+/yr.

Magento Open Source: covered by extensions, Mageworx Companies ($299 + 12mo support), Aitoc B2B Suite (~$899), or BSS Companies (free + paid tiers). Combine with Aitoc Quote Workflow ($299, $799) to fill the approval gap. Total: $1-3k one-time vs $30k+/yr for AC.

The honest trade-off: AC ships a more polished UI, vendor-supported upgrades, and 24/7 SLA. OS extensions cover ~85% of the feature set at 5% of the cost, the remaining 15% is mostly "nice-to-have" admin polish. For most wholesale stores under $10M GMV, OS + extensions is the right call.

The shipped pattern across 40+ B2B builds:

• Buyer side: add items to a cart → click "Request a quote" instead of checkout → quote enters "Submitted" state. Buyer can attach notes ("we need this delivered split across 3 warehouses").
• Sales-rep side: internal admin queue shows new quotes. Rep opens the quote, can edit line-item prices, add discount %, override shipping, attach payment terms (Net-30 / Net-45 / Net-60), set expiry (default 14 days). Quote moves to "Counter-offered".
• Buyer review: email link → sees revised quote with line-by-line price changes highlighted → accepts or counter-counters (limit 2 rounds typically).
• Conversion: "Accept" converts the quote to a placed order with the agreed price + payment terms locked in.

PDF generation: auto-generated on every quote save, with company logo, customer billing/shipping address, line items + per-line pricing, tax breakdown, payment terms in the footer, expiry date in red. Library: Dompdf or mPDF for Open Source; native module for Adobe Commerce.

Expiry rules: stale quotes (past expiry) flip to read-only; buyer can request re-quote which spawns a new draft pre-filled with the old line items at current pricing.

Net-30 isn’t a payment method, it’s a credit-extension contract. The Magento mechanics:

1. Customer-segment configuration: "Verified Wholesale" customer group has Net-30 payment method enabled; new buyers default to "Card-only" until verified by AR.
2. Order placement: buyer chooses "Net-30 / Invoice me" at checkout. Order is placed in "Pending Payment" state, no card charge.
3. ERP push: order webhook fires to NetSuite / SAP / Tally / Odoo as a Sales Order with terms = Net-30. Invoice is generated in the ERP at fulfillment, not in Magento.
4. Invoice tracking: ERP pushes back invoice number + due date to Magento (so the buyer dashboard shows "Invoice #INV-1234, due Dec 15"). AR aging stays in the ERP.
5. Payment received: ACH / wire / cheque hits the bank → AR marks paid in ERP → ERP webhook marks Magento order "Paid" → auto-emails buyer the receipt.
6. Dunning: ERP sends 7-day, 14-day, 30-day-overdue emails. If 60+ days overdue, customer-group moves back to "Card-only" until cleared.

Critical: the source of truth for AR is the ERP, not Magento. Magento just shows the buyer their invoice status, the finance team operates entirely in the ERP.

Surprisingly granular. Magento’s native pricing stack lets you layer:

• Customer-group prices: per SKU, per group (Bronze / Silver / Gold / Platinum). 4 prices for 1 SKU is trivial; we’ve done 24 groups on a paint distributor.
• Tier prices: per group, per quantity-bucket. e.g. Gold tier: $10 at 1-99, $9 at 100-499, $8 at 500+.
• Special prices: per SKU, per customer (not just group), with start/end dates. Useful for "this one big buyer gets $7.50 forever".
• Cart price rules: conditional discounts ("any 100 SKUs from category X = 10% off") layered on top.
• Shared-catalog pricing (Adobe Commerce only): a complete alternate price-list per company-account. Open Source approximation: customer-segment + cart rules.

The wholesale reality, a single SKU might have 12 different prices across your buyer base. Magento handles that; Shopify B2B price lists hit limits around 4-5 tiers.

Performance note: with >500 active customer-group prices per SKU, indexing slows. Mitigation: keep group count under 30, push customer-specific overrides to "special prices" instead of new groups.

Different problems, different tools.

Requisition lists are for SKU lineups buyers reorder manually but frequently. The classic example: a hospital procurement officer maintains a "Monthly cleaning supplies" list with 47 SKUs. They open the list, click "Add all to cart", review quantities, place the order. Native Magento feature (Adobe Commerce); via Wyomind or Mirasvit on Open Source.

• Buyer is in the loop on every order
• Quantities can vary each cycle
• Lineup itself can be edited / shared with co-workers ("share with Procurement team")
• Multiple lists per buyer is normal (one for cleaning, one for office supplies, one for janitorial)

Recurring subscriptions are for SKUs that auto-replenish without buyer involvement. Example: a cleaning-services company auto-receives 20 cases of paper towels every Monday. No order placement, no buyer action, just a charge + ship event.

• Fully automated, buyer is not involved per-cycle
• Quantities are fixed (or fixed with skip-this-month buttons)
• Cadence is fixed: weekly / monthly / quarterly
• Best for fast-moving consumables with predictable burn

Stack: Magesterix Subscriptions, Aheadworks Subscriptions, or custom (built on Stripe Subscriptions or Razorpay for India). Avoid building from scratch, subscription billing has 30 corner cases (failed cards, prorated upgrades, paused subscriptions, regional tax).

Rule of thumb: ~70% of wholesale stores need only requisition lists. ~20% need both. ~10% (heavy MRO consumables) lean subscriptions.

The honest list of what works in 2026:

• NetSuite: direct integration via SuiteScript + REST API. Connectors: Patchworks (mid-market, $400, $800/mo), Celigo Integrator.io ($600, $1,200/mo), Folio3 NetSuite-Magento connector (one-time + support). Custom-built: $20, $40k for a clean implementation. Real-time stock + price; near-real-time order push.
• SAP (S/4HANA, Business One): IDoc-based (legacy) or OData (modern). Connectors: Pixafy SAP-Magento, Boltic SAP, Alumio. Custom: $30, $60k due to schema complexity. Batch sync (every 5-15 min) is the norm; real-time is achievable but pricey.
• Tally: XML-over-HTTP integration (Tally’s native pattern). Connectors: tdlexpert.com Tally-Magento bridge, custom modules from Indian dev shops ($3, $8k). Strong India-market choice; pairs with Razorpay for NEFT/IMPS payment.
• Odoo: XML-RPC API. Connectors: Magemodule Odoo bridge, EmiproTech Odoo-Magento. Custom: $10, $20k. Good for SMB wholesalers who run Odoo ERP + Magento commerce.
• Microsoft Dynamics 365: OData / Dataverse APIs. Connectors: Sana Commerce (built specifically for Dynamics), e-bridge by CData. Custom: $25, $50k.
• Zoho Inventory / Books: direct REST. Connectors: SkyVia, Zapier (small scale). Custom: $5, $15k. Good for SMB.

Decision rule: if you’re under $5M GMV with standard SKU master, a connector + middleware is faster (4-6 weeks). Above $5M with complex multi-warehouse / multi-currency / IDoc-based SAP, custom direct integration is more reliable and 3-year-cheaper despite the higher upfront cost.

5,000 lines is the high end of normal; 12,000 lines is doable with care; 50,000 lines needs a bulk-order asynchronous queue.

• 0-500 lines: synchronous. Submit → validate → cart → checkout in <5 seconds. No special handling needed.
• 500-5,000 lines: still synchronous but with a progress bar. Validation runs in chunks of 200 SKUs at a time to avoid PHP timeout. Total time: 10-30 seconds. Stock + price checks happen before cart insertion.
• 5,000-12,000 lines: asynchronous. CSV uploads → queue job → user gets an email with a "review your prepared cart" link in 1-3 minutes. SKU validation, price-snapshot, and stock-availability happen in the background. Buyer reviews + submits.
• 12,000+ lines: custom queue + multi-batch order (split into 2-3 separate orders to keep the order_items table sane). Often combined with multi-warehouse splitting.

Validation pre-submit: always show buyers (a) which SKUs aren’t found, (b) which are out of stock, (c) which have price differences from their list. Letting them edit / remove problem rows pre-submit cuts post-order disputes 80%.

Anti-pattern: never run a 5,000-line CSV through Magento’s standard add-to-cart events, you’ll trigger the catalog-rule indexer 5,000 times. Use direct quote-item insertion bypassing event observers.

Region-specific. Each has a clear preferred path.

ACH (United States): via Stripe Payments (offers ACH Direct Debit + Plaid micro-deposit verification), Authorize.Net eCheck, or NACHA-compliant gateways like Forte. Stripe is easiest to integrate (official Magento module + 2-day verification). Authorize.Net is cheapest at scale (~$0.10 per transaction vs Stripe’s 0.8% capped at $5).

SEPA Direct Debit (EU): via Stripe SEPA, Mollie SEPA, GoCardless. Mollie has the strongest Magento module + SEPA mandate management. GoCardless is purpose-built for B2B recurring debits and has the best webhook reliability for failed-payment retries.

NEFT / IMPS / RTGS (India): via Razorpay, PayU, or HDFC FirstData. Razorpay has the most mature B2B flow, supports NEFT, IMPS, RTGS, and UPI for sub-500k INR transactions. Direct bank transfers for >500k INR with reconciliation via virtual account numbers.

Bacs (UK): via GoCardless or Modulr. GoCardless dominates here.

Reconciliation pattern: all bulk-payment methods are async, the order is placed in "Payment Pending" state, buyer sees the bank-transfer instructions or initiates the debit, payment confirmation comes back via webhook 1-3 days later, order moves to "Paid" and fulfillment kicks off. Build the UX around this delay, pretending it’s instant breaks trust.

Different shapes of business, not "Magento better" or "Shopify better".

Shopify Plus B2B wins when:

• B2B is <30% of revenue and you’re primarily D2C
• One buyer per company (no role hierarchy)
• Quote workflow is single-level approval at most
• Customer pricing is "wholesale price + Net-30" with no per-SKU complexity
• You don’t need real-time ERP integration (5-min Celigo batches are fine)
• Time-to-launch matters more than long-term flexibility

Magento wins when:

• B2B is >40% of revenue (or pure-B2B)
• Companies with multi-buyer roles + multi-step approval are common
• Customer-segment pricing has 5+ tiers or per-SKU per-customer overrides
• ERP integration is real-time-critical (NetSuite / SAP / Tally / Odoo)
• Bulk-order CSV (5,000+ rows) is a frequent buyer flow
• Requisition lists + recurring orders are core to retention
• You need ACH (US) + SEPA (EU) + NEFT (India) on the same store

The Shopify Plus B2B 2025 update narrowed the gap: companies, customer-specific catalogs, Net-30, draft orders all shipped. But the gaps that remain, multi-step approval, 24+ pricing tiers per SKU, real-time IDoc-based SAP integration, 5,000-row CSV with pre-submit validation, are the gaps that matter for serious wholesale.

Wholesale stores often need products that exist only for specific buyer-segments, restricted-use SKUs, OEM-only items, exclusive bulk packs, or trade-channel pricing that shouldn’t be visible to anyone else.

Magento Open Source mechanics:

• Customer-group product visibility: via Aitoc Customer-Segment Catalog or BSS Hidden Categories ($199, $499). Each product has a "visible to groups" flag, logged-out users + non-matching groups see a 404 or redirect to login.
• Category-level visibility: hide entire categories from anonymous + non-trade groups. Trade buyers see "Wholesale Only" subtree; everyone else doesn’t.
• Login-walled storefront: entire store requires login. New visitors see only a login page + "request trade account" form. Used by pure-B2B distributors who don’t want their catalog scraped or visible to retail customers.
• Per-company custom catalog (Adobe Commerce Shared Catalogs): each company-account gets its own catalog snapshot, SKUs they shouldn’t see are simply not in their feed.

SEO consideration: hidden trade catalogs should return HTTP 404 (not 403) for non-authorised users to stay out of Google’s index. Pair with robots.txt deny rules for the URL paths and a separate sitemap that excludes the trade-only sections.

Pricing visibility: a common ask, show product but hide price until login. Native cart-rule: "Display price = $0 / login to see" with a "Request quote" CTA replacing the price. Done with a small Hyvä template override.

Common path. Risk is real but quantifiable.

The typical custom-portal stack: Laravel / Django / Rails app + MySQL/Postgres + manual ERP scripts. Built 5-10 years ago, hard to hire for, no upgrade path, every new feature is a custom build. Maintenance is a tax on the dev team.

Migration plan (12-20 weeks):

1. Data audit (week 1-2): companies, buyers, customer-group pricing rules, requisition lists, open quotes, AR balances. Map to Magento entities, companies → B2B Companies module, buyers → customers, segment pricing → customer-group prices.
2. Feature parity matrix (week 2): what does the custom portal do that Magento doesn’t out-of-box? Build the gap list. Usually 6-12 items, 3-5 of which need custom modules.
3. Magento + extensions setup (week 3-5): base Magento, Hyvä theme, B2B extensions, ERP connector, payment gateways.
4. Custom-portal data export (week 6): SQL dumps + CSV exports of all customer + order + pricing data. Validate counts.
5. Magento data import (week 7-9): via dataflow / API / direct SQL. Spot-check 100 customers + 50 orders for accuracy.
6. Parallel run (week 10-14): both portals live. New orders go to Magento; old portal is read-only for AR / reporting. Buyers get a "we’ve moved" email + reset-password link.
7. Cutover (week 15): DNS flip. Old portal stays read-only for 90 days for any AR queries.
8. Stabilisation (week 16-20): bug fixes, buyer training, ERP sync tuning.

Risk hotspots: (1) password migration, you can’t move hashes if the algos differ; force a reset email at first login. (2) saved-card tokens, need to re-tokenise at the new gateway via account-updater service. (3) custom-portal-only URLs, build a redirect map covering >95% of indexed traffic before DNS flip.

Real ranges from 40+ shipped projects:

Greenfield Magento Open Source B2B (no migration):

• Timeline: 12-16 weeks build + 4 weeks stabilisation
• Build cost: $30k, $80k depending on segment-pricing complexity + ERP integration depth
• Extensions: $3k, $8k one-time (Companies, Quote Workflow, Subscriptions, etc.)
• Hyvä theme licence: $1,000 one-time
• Hosting: $400, $1,500/mo (Cloudways / dedicated)
• 3-year TCO: $80k, $200k

Migration from Shopify Plus / SAP Hybris / custom portal:

• Timeline: 16-24 weeks build + 4 weeks parallel run + 4 weeks stabilisation
• Build cost: $50k, $140k
• Data migration: $10k, $30k (companies, buyers, pricing, AR balances)
• ERP re-integration: $15k, $50k depending on system
• 3-year TCO: $130k, $320k

Adobe Commerce B2B (vendor-supported):

• Same build cost as Open Source + Adobe Commerce license $30k, $80k/yr based on GMV
• 3-year licence: $90k, $240k on top of build cost
• Pays for itself when (a) you’d need 24/7 SLA anyway, or (b) you’re >$10M GMV with full B2B usage

Below $5M B2B GMV: Open Source + extensions is the right call. $5, $10M: close call, depends on team. Above $10M: Adobe Commerce + Cloud often wins on operational cost despite the licence.

Cheapest B2B build that’s not a regret: $30k. Anything cheaper skips ERP integration or quote workflow and you’ll rebuild within 18 months. The honest floor.
