Inventory & PO Management
Daily automation checks low stock against reorder thresholds, prevents duplicate POs, calculates optimal quantities.
E-commerce Operatorops and IT teams
What it does
You get automatic alerts when stock runs low, ensuring you never miss a reorder while avoiding duplicate purchase orders. The system calculates optimal quantities for each item, groups them by supplier, and sends you clear email summaries so you can approve orders instantly without manual checks.
Step by step
- Configure an Airtable trigger to watch for records where current stock is less than or equal to the reorder point field.
- Use a code step to subtract current inventory from the calculated optimal restock quantity and store the result in a variable.
- Query the Airtable PO table using a filter that matches the product ID and checks if the status is not 'Sent' or 'Cancelled'.
- Create new records in the Purchase Orders table with fields for supplier, item details, quantity, and initial status set to 'Pending'.
Where the LLM does the work
- Generate a human-readable email body that lists each product's name, SKU, current stock level, and requested restock quantity.
- Format the grouped order summary so it clearly separates items by supplier for easy reading in the Brevo template.
- Draft a polite subject line and closing remark that matches the professional tone of your company's procurement process.
Watch out for
Floating point arithmetic can cause rounding issues in quantity calculations, use integer conversion or a rounding library to ensure whole units.
Brevo email templates may break if special characters are not escaped, sanitize all product names before injecting them into the HTML body.

The agent brief
Everything your agent needs, including the gotchas. Copy it and go.
You are helping me build the following AI agent workflow. ## Goal Inventory & PO Management: Daily automation checks low stock against reorder thresholds, prevents duplicate POs, calculates optimal quantities. ## Specification - What it does: You get automatic alerts when stock runs low, ensuring you never miss a reorder while avoiding duplicate purchase orders. The system calculates optimal quantities for each item, groups them by supplier, and sends you clear email summaries so you can approve orders instantly without manual checks. - Trigger: On a schedule (Scheduled · daily at midnight and 1:00 AM) - Autonomy: You approve along the way - Expected setup effort: about an afternoon - Tools/services involved: - Airtable: Storing product stock, supplier data, and purchase order records - Brevo: Sending automated email notifications to suppliers - Code: Calculating reorder quantities and grouping POs by supplier ## Known pitfalls, handle each one explicitly in your implementation 1. Floating point arithmetic can cause rounding issues in quantity calculations, use integer conversion or a rounding library to ensure whole units. 2. Brevo email templates may break if special characters are not escaped, sanitize all product names before injecting them into the HTML body. ## Reference implementation https://n8n.io/workflows/5815 (workflow template) Fetch and inspect this before building. If it matches my stack, adapt it; if not, rebuild the pattern with my tools. ## Process requirements 1. Before building: ask me which of the listed tools I actually use and what my platform is (n8n / Make / code / other). Do not assume. 2. Adapt the pattern to my answers; do not force the reference stack. 3. Address every pitfall above; tell me how you handled each. 4. Provide a test plan I can run before letting this touch real data. 5. Ask before any step that sends messages, modifies data, or spends money.

Frequently asked questions
Can I use a different Spreadsheet than Airtable?
Yes. Airtable is only the example spreadsheet in this recipe. The same flow works with Baserow, Excel and Google Sheets. Swap the spreadsheet connection and keep the rest of the setup as written.
Want this running in your business?
This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.
Who it's for
Also fits E-commerce Operator.
Ops-IT teams triaging their own internal requests get the same pattern, different queue.
