One ERP for Two Legacies: Digitizing Bangladesh's Tea Auction-to-Retail and Textile Operations at Enterprise Scale

Brain Station 23’s team ran a full discovery-to-blueprint cycle — stakeholder workshops, process mapping, and gap analysis — before authoring detailed Software Requirement Specifications for both entities. The resulting solution architecture configures and extends Odoo across 10 tightly integrated modules, including four custom-built extensions (Auction Management, Blend Order Management, the Pricing Engine, and Return Management) that don’t exist in standard Odoo:

• Auction Management (custom): bulk catalog import, lot-level QC entry with automatic export/import tax classification, auction purchase approval with auto-generated PO and receipt, and warehouse-to-factory stock transfer with full lot traceability.
• Blend Order Management (custom): blend indents from factory planners, blend order creation against “virgin stock,” lot-locking to prevent double allocation, and blend execution that converts raw lots into Semi-Finished Goods with yield reporting.
• Procurement & SCM: Store and Purchase Requisition with multi-level approval matrices, RFQ-to-vendor-portal workflows, automated Comparative Statement generation, and PO issuance with landed cost and variance tracking for import purchases.
• QC-Gated Receiving: a four-category receiving workflow (Raw Materials, Packaging, Spare Parts, Non-Inventory) routing goods through QC Pending → QC Control → QC Passed → store, using Pull/Push routing rules configured against Odoo’s inventory engine.
• Primary & Secondary Sales / Distribution: a Factory → Division → Depot → Dealer/Retailer model across 26 divisions, with stock indenting, dealer credit limit enforcement, receivables generation on delivery, and secondary (dealer-to-retailer) sales captured for market visibility without touching the financial ledger.
• Custom Pricing Engine: MRP, Trade Price, National and Regional Discounts, Net Price, and Dealer Price computed and applied with division-wise variation and controlled price-change scenarios for new versus existing stock.
• Commercial Sales & Export: Proforma Invoice and Letter of Credit workflows with COO-level approval, LC value enforced as a hard credit ceiling against shipment execution.
• Finance: integrated Accounts Payable/Receivable, Fixed Asset and CWIP management, Straight-Line depreciation, deferred tax tracking, multi-dimensional Budget Management (department, cost center, SKU), and manufacturing costing with real-time WIP valuation.
• Petty Cash, Expense, and Approval frameworks with GL-head and daily-limit controls for field and depot officers, plus a Management Dashboard for cross-entity visibility.

The entire platform is deployed on AWS with PostgreSQL, accessible through web browsers and the Odoo mobile app, and designed to support a 1,000+ user base spanning both Ispahani Tea Limited and Pahartoli Textiles Limited under one program. The engagement is being delivered by a four-person Brain Station 23 team — one Project Manager, two Developers, and one combined Business Analyst/QA resource — against a 10-month, 850-day delivery plan spanning Requirements Analysis, Documentation & Sign-off, Configuration & Custom Development, Internal Testing, UAT, Training, Go-Live, and Post Go-Live Hypercare support.
