Inventory Aging Report
Inventory Aging ReportTrack how long stock has been sitting in your warehouse with precise aging buckets, valuations, and exportable reports — for any Odoo version from 15 to 19.
Overview
The Inventory Aging Report module gives warehouse and finance teams a clear picture of stock age distribution. It breaks on-hand inventory into up to 6 configurable aging periods (e.g. 0-30, 31-60, 61-90 days …) and shows the quantity and landed cost value per bucket — helping you spot slow-moving or obsolete stock instantly.
Reports can be generated per Warehouse or per individual Stock Location, filtered by product or category, and exported to both PDF and Excel (.xlsx).

Key Features
6 Aging Buckets
Set a custom period length (e.g. 30 days). The report auto-builds 5 consecutive buckets plus an overflow bucket for the oldest stock.
Cost Valuation
Each bucket shows both quantity on hand and the book value sourced directly from posted accounting move lines (AVCO / FIFO compatible).
Warehouse & Location
Switch between a warehouse-level summary (uses lot stock location) or a granular per-location breakdown — all in one wizard toggle.
Product & Category Filter
Focus on a specific set of products or an entire product category. The wizard enforces mutual exclusivity to keep reports clean.
PDF Report
QWeb-rendered A4 PDF with full aging table, company header, date, period length info, and a clean tabular layout ready for management.
Excel Export (.xlsx)
Multi-section xlsx workbook via xlsxwriter: one section
per warehouse/location, color-coded headers, bold totals, and
Qty/Value sub-columns per period.
Multi-Company
Company selector on the wizard ensures accounting move lines and warehouses are filtered to the correct company context.
Raw SQL Performance
Core data queries use direct SQL (not ORM search loops) against
account_move_line × stock_move for speed
even with large datasets.
Arabic / English Ready
UTF-8 encoded throughout. Works seamlessly with right-to-left Arabic interfaces and GCC region Odoo deployments.
How It Works
- Open the wizard from Inventory → Reporting → Inventory Aging Report.
- Select your Company, filter type (Product or Category), and the specific products/categories.
- Set the From Date (the reference date — aging is calculated backwards from this date) and Period Length in days.
- Choose report basis: Warehouse (recommended) or individual Locations.
- Click Print PDF for a management-ready PDF, or Print Excel to download an xlsx workbook.
