Question 1

How does Medusa B2B compare to Shopify Plus B2B and SAP Commerce Cloud?

Accepted Answer

**Shopify Plus B2B** (April 2026 list pricing $2,500/mo + variant-based add-ons) is Shopify's bolt-on B2B layer. It supports company accounts and tiered pricing but the depth is shallow — multi-step approval chains require Shopify Flow workarounds, customer-specific catalogues are limited, integration with Indian ERPs (ERPNext, Tally) requires third-party middleware, GST + e-invoicing handling needs additional apps, and the **0.5–2% GMV transaction fee** on non-Shopify Payments stacks on top of the monthly licence. Net cost for a ₹50 cr B2B distributor: ~₹40–70 L/year all-in.

**SAP Commerce Cloud** is the enterprise option — robust but with $300k–1M+ implementation cost, $50k–200k/year licence fees, multi-year deployment timelines, and SAP-ecosystem lock-in. Realistic for ₹500 cr+ operators only.

**Medusa B2B (Mithtech-implemented):** the platform is **MIT — zero licence fees, zero GMV tax, zero per-order charges.** Mithtech implementation is ₹4–15 L one-time + ₹10–40k/month hosting. For a ₹50 cr distributor that's typically ~₹15 L year-one all-in vs Shopify Plus B2B's ~₹40–70 L. Payback is typically under 6 months.

**When Shopify Plus B2B still wins:** small B2B operations under ₹5 cr GMV that have no integration depth requirements and a small team — the simpler operating model can offset the cost gap. **When Medusa B2B wins:** every other case, especially anything requiring deep ERPNext / GST / customer-specific catalogue / multi-currency / multi-warehouse logic.

Question 2

Does Mithtech use the official Medusa B2B starter?

Accepted Answer

Yes — we start from **github.com/medusajs/b2b-starter-medusa** rather than building from zero. The official starter covers the foundational B2B primitives — Company doctype, Employee doctype with role-based permissions, Quote-to-Order workflow, basic approval chains, customer-group pricing — and is maintained by Medusa Inc alongside the core platform. Building on the starter means clients get **production scaffold + Mithtech-customised configuration in 8–20 weeks rather than 12+ months of greenfield engineering** with comparable feature parity.

Mithtech then extends the starter with: (a) India-specific GST + e-invoicing modules with HSN/SAC code handling and IRN generation, (b) ERPNext integration depth (Customer master with credit limit + AR, Sales Order automation, dunning), (c) Polygin WhatsApp B2B touchpoints, (d) DocuSeal e-sign for dealer agreements and credit applications, (e) Smartflo CCaaS click-to-call from the Admin, (f) Frappe CRM upstream pipeline integration, (g) industry-specific Modules (pharma compliance, agri seasonal-pricing, FMCG depletion-based reordering), and (h) Mithtech-built bulk-order tooling and reorder-from-history shortcuts. All extensions live in the Mithtech-owned Git repo as TypeScript Modules following Medusa SDK conventions — never as patches to upstream code.

Question 3

Can Medusa B2B handle complex pricing — different prices for different customer groups, volume breaks, contracts, regional multipliers?

Accepted Answer

Yes — this is exactly where Medusa.js shines vs Shopify Plus. Medusa's **Pricing Module** + **Promotion Engine** + Mithtech's custom B2B Pricing Module support every common B2B pricing pattern in production:

1. **Customer-group pricing** — define pricing rules per Customer Group (Distributor Tier 1, Tier 2, Direct Dealer, Sub-Dealer) and prices auto-resolve at checkout based on the logged-in customer.
2. **Volume breaks** — quantity-based discount tiers with multi-currency support (e.g., 1–10 units at price A, 11–50 at B, 51+ at C).
3. **Contract pricing** — customer-specific overrides for negotiated rates with date-bounded validity (e.g., 'Customer X gets ₹240/unit on SKU Y from 1 Apr 2026 to 31 Mar 2027').
4. **Regional multipliers** — different base prices per region (North / South / East / West) with currency-aware conversion for cross-border B2B.
5. **GST-inclusive vs exclusive display** — toggle per buyer's preference with automatic recomputation.
6. **Promotional layering** — campaign-based stackable or exclusive promotions on top of the base contract price (free shipping, additional X%, free units, BOGO).
7. **Quote-driven exceptions** — sales reps can issue one-off quotes that override standard pricing for a specific opportunity, with manager-approval gating above thresholds.

All pricing logic lives as code in the Mithtech-owned Modules — auditable, testable, version-controlled. Pricing changes are PRs, not panic edits in a Shopify admin.

Question 4

How do net terms, credit limits, and ERPNext AR integration work?

Accepted Answer

Mithtech's standard B2B credit-and-collections pattern, deployed across multiple production clients:

**Setup:** Each B2B Customer in Medusa is mirrored to ERPNext's Customer master with `payment_terms_template` (Net 30 / Net 45 / Net 60 / Net 90 / COD) and `credit_limit` (per-customer rupee cap). Customer Groups inherit defaults; individual customers can override.

**Order placement:** When a B2B buyer places an order in the Medusa storefront, a **pre-checkout credit check** fires — the Mithtech-built ERPNext bridge queries `credit_limit` minus `total_outstanding` (sum of unpaid Sales Invoices) and compares to the order value. Three outcomes: (a) **within limit** — order auto-approves and proceeds; (b) **exceeds limit but within 110%** — order is held in Pending Approval state with a notification to the AR manager; (c) **exceeds 110%** — order is blocked with a polite UI message and the AR team is alerted to either collect outstanding or extend the limit.

**Dispatch:** On warehouse pick + ship, ERPNext auto-creates the GST-compliant Sales Invoice (with IRN generation if the client uses Mithtech's [GST Compliance](/products/gst-compliance) addon), the Delivery Note, and updates inventory. A copy of the invoice goes to the buyer via email + WhatsApp (Polygin Integration).

**Collections:** Configurable dunning chains in ERPNext + n8n — Day -3 reminder, Day 0 due notice, Day +7 first follow-up, Day +14 escalation, Day +30 manager intervention. All touchpoints support email, WhatsApp (Polygin), and Smartflo dialer call-back. Collections agents see a unified ageing view across all customers.

**Statement of account:** Buyers can pull their own statement on-demand from the B2B portal — list of all invoices, payments, credit notes, current outstanding, ageing buckets — fed live from ERPNext. Reduces 'send me my statement' calls by 60–80% in production deployments.

Question 5

What does Mithtech actually build and modify on top of Medusa for a B2B deployment?

Accepted Answer

Mithtech is an expert Medusa B2B implementor — we **modify, develop, and deploy** the open-source platform. Concrete scope from production deployments:

1. **Custom Medusa Modules** (TypeScript, following Medusa SDK conventions) — Company Accounts with employee hierarchies, Approval Workflows, Customer-Specific Pricing, Quote-to-Order, Net Terms + Credit Limit checks, Bulk Order tooling, Reorder + Subscription engines, India GST module with HSN/SAC and IRN.
2. **Custom Admin extensions** — React widgets surfacing ERPNext context (credit limit, AR ageing, AMC status, last-visit notes from Frappe CRM) inside the Medusa order view; bulk-action workflows for catalogue management; custom dashboards for B2B-specific KPIs.
3. **Custom B2B storefront** — Next.js or TanStack Start with role-aware UI (buyer / approver / admin), order history, reorder shortcuts, downloadable GST invoices, statement-of-account view, mobile-optimised for field-sales reps.
4. **ERPNext integration bridge** — Mithtech-built bidirectional sync of Customer / Sales Order / Sales Invoice / Stock / Payment Entry, GL postings on order completion, credit-limit enforcement at checkout, dunning automation.
5. **Polygin Integration bridge** — WhatsApp templated messages for order confirmation, dispatch tracking, payment-due reminders, statement-of-account on demand, all driven from Medusa events.
6. **Smartflo Integration bridge** — click-to-call from the Admin into Smartflo's CCaaS for sales follow-up; inbound calls auto-attached to Medusa customer records with call-recording links.
7. **DocuSeal integration** — credit application forms with digital signature, dealer agreements, NDA flows, all linked back to the Medusa Company record.
8. **Frappe CRM upstream integration** — Lead + Deal pipeline feeding the B2B portal; deal-won automatically provisions Company + Employee records in the Medusa B2B portal.
9. **AI-augmented email-to-order** — n8n workflow + AI Agents parsing inbound PO emails, extracting line items via LLM with schema validation, creating draft Sales Orders for human review, pushing approved orders to Medusa + ERPNext.
10. **Deployment** — Docker Compose for operator, Kubernetes Helm for scale, or Medusa Cloud push-to-deploy. Database tuning (Postgres index optimisation on Customer/Order/Invoice tables), Redis cache configuration, Bull queue tuning for the dunning + email workflows.

All work delivered as Mithtech-owned Git repository — TypeScript source, deployment scripts, runbook, 90-day post-go-live support window. Client owns IP.
