Our client is a global B2B2C aggregator in the pet supplies industry with operations across North America, Europe, and the UK. For over 40 years, they have played a pivotal role in connecting pet retailers (B) with premium suppliers (B) — and are now evolving into a digital platform that also serves end customers (C) directly.

Their goal: build a closed yet flexible marketplace that supports direct-to-consumer ordering while preserving complex business workflows for retailers and suppliers.

Moving to a B2B2C marketplace architecture introduced multifaceted operational and technical challenges that spanned both wholesale and retail user journeys:

1. Tax Compliance Across Stakeholders

• The client was responsible for calculating, collecting, and remitting taxes on behalf of suppliers — for both retailer orders and consumer purchases — across multiple tax jurisdictions and product categories.
• Required mapping of different tax rules for wholesale exempt buyers versus retail consumers
• Complexity increased for cross-border transactions, especially in the UK and EU with VAT thresholds and reverse charge mechanisms

2. Multi-Seller Order Complexity

Orders often involved multiple suppliers, requiring:

• Automated order splitting
• Separate tracking numbers per shipment
• Unified order summaries
• Distributed return workflows
• Automated shipment status syncs from various carriers
• Order cancellation coordination between sellers and end users

3. B2B Wholesale Operational Needs

Retailers on the platform expected capabilities like:

• Minimum Order Quantities (MOQs) enforced per supplier/product
• Negotiated rates and tiered discounts, based on purchase history and contract terms
• Custom payment terms (e.g., Net 30, Net 60), with invoice-based checkout
• Bulk ordering tools like CSV uploads, quick order forms, and requisition lists
• Partial return and credit workflows at the line-item level
• Multi-location delivery support, allowing one order to ship to multiple store branches

4. B2C Retail Expectations

End consumers required a smooth, modern shopping experience, including:

• Real-time multi-seller product discovery
• Personalized recommendations and cross-sells
• One-click returns, refund automation, and mobile-optimized checkout
• Transparent shipment tracking across vendors
• Cart retention, wish-list functionality, and flexible payment options like BNPL

5. Supplier Management at Scale

With hundreds of vendors onboard, the client needed a centralized system to manage:

• Onboarding and vetting workflows
• Product feed validation and normalization
• SLA enforcement and violation alerts
• Sales performance analytics
• Supplier-specific rules for promotions, return windows, and shipping cutoffs

6. Price Conflicts and Governance

Multiple sellers often listed identical or similar SKUs, causing price wars. The platform needed:

• Dynamic pricing controls with seller-based priority
• Listing moderation tools
• Brand-level enforcement policies
• MAP (Minimum Advertised Pricing) policy compliance

7. Reporting & Insights for All Parties

Suppliers, retailers, and internal stakeholders all needed access to:

• Real-time dashboards
• SKU-level and brand-level sales insights
• Dispute resolution tracking
• Inventory performance reports
