The Pricelist & Discount Engine governs B2B pricing: customer and group price agreements with validity dates, quantity break matrices, margin-floor protection, and approval workflows when reps discount past their authority. For wholesalers and distributors where every key account has negotiated prices and uncontrolled rep discounting erodes margin invisibly. Planned features include agreement-based pricing per customer with renewal alerts, quantity and pack-size break tables, promotional windows with automatic expiry, margin floor rules that block or escalate below-cost sales, discount authority limits by role with approval chains, price history per customer-product pair, and margin impact preview on every order. This app is currently in development on the ECOSIRE build pipeline. It will ship first for Odoo 17, 18, and 19 simultaneously, with an ERPNext port following on the v15/v16 track — the same triple-version coverage as every live ECOSIRE app. One-time license, free updates within your major version.
