How to Track Inventory Reorder in Postgres — Without Writing SQL
Managing inventory reorders manually is a nightmare for founders without a data team. Postgres offers powerful tools like timestamptz for global tracking and date_trunc for period analysis, but writing these queries is daunting. You need complex CTEs and window functions to calculate running totals and reorder points accurately.
“Which products have fallen below their minimum stock level and need reordering today?”
This prevents stockouts and lost revenue by identifying critical shortages instantly. It replaces complex JOINs between product and warehouse tables with a simple request.
You get: A list of product names, current stock levels, and the required reorder quantity.
“What is the average monthly consumption rate per product to determine new reorder points?”
Static reorder points fail as demand shifts. This uses window functions to calculate moving averages, removing the need for manual spreadsheet forecasting.
You get: A table showing product IDs and their calculated monthly burn rate.
“Which suppliers have the longest lead times for items currently under the reorder threshold?”
Prioritizing orders based on lead time ensures items arrive before stock hits zero. This eliminates the need for multi-level subqueries across supplier and order tables.
You get: A ranked list of suppliers and their average delivery days for critical items.
“How many units of each product were reordered in the last quarter compared to the previous quarter?”
Understanding seasonal trends helps optimize capital allocation. It replaces tedious date_trunc and aggregation logic.
You get: A comparison table showing quarterly reorder volumes per SKU.
“Which high-value items are at risk of stockout within the next 14 days based on current sales velocity?”
Protecting high-margin revenue is critical for cash flow. This replaces predictive SQL logic that calculates daily velocity against current inventory.
You get: A priority list of high-value products with estimated days until stockout.

Frequently asked questions
Do I need to know SQL to get these answers?
No. You type the question in plain English exactly as written above, and the AI writes and runs the PostgreSQL query against your database for you. You can inspect the generated query if you want to, but you never have to write it.
Is it safe to connect my production Postgres database?
Yes — connections are read-only by default, so nothing can be modified or deleted. For extra safety, create a dedicated role with SELECT-only grants or connect a read replica.
How does the system handle complex timestamptz conversions across different warehouse timezones?
The AI automatically normalizes all timestamps to a consistent UTC reference before calculating reorder windows.
