Restaurant POS Orders and Inventory
Captures POS orders, processes payments, updates stock levels, and logs sales to Google Sheets in real time.
founders and execsops and IT teams
What it does
Streamline your restaurant operations by automatically capturing orders, processing payments, and updating stock levels without manual entry. You get real-time sales reports in Google Sheets and accurate inventory tracking that prevents overselling while you focus on serving customers.
Step by step
- Configure the POS system webhook to trigger the workflow whenever a transaction completes.
- Set up the payment gateway API credentials and define the specific endpoint for processing refunds.
- Map the inventory management tool's SKU fields to match the extracted line items from the order.
Where the LLM does the work
- Prompt the LLM to parse unstructured receipt text into structured JSON containing item names, quantities, and prices.
- Instruct the model to detect ambiguous menu descriptions like 'large fries' by mapping them to standard inventory SKUs.
- Ask the LLM to summarize daily sales trends in natural language for the Google Sheets summary column.
Watch out for
Currency formatting differences between regions can break parsing, normalize all monetary values to a single format before sending them to the LLM.
Inventory updates might race if multiple orders arrive simultaneously, implement a queue or locking mechanism to prevent overselling.

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 Restaurant POS Orders and Inventory: Captures POS orders, processes payments, updates stock levels, and logs sales to Google Sheets in real time. ## Specification - What it does: Streamline your restaurant operations by automatically capturing orders, processing payments, and updating stock levels without manual entry. You get real-time sales reports in Google Sheets and accurate inventory tracking that prevents overselling while you focus on serving customers. - Trigger: Triggered by an event (Event · on new order from POS) - Autonomy: Fully hands-off - Expected setup effort: a few focused days - Tools/services involved: - POS System: retrieve order details and payment info - Payment Gateway: process transactions securely - Inventory Management Tool: update stock levels automatically - Google Sheets: generate real-time sales reports - OpenAI Chat Model: extract and structure order data ## Known pitfalls, handle each one explicitly in your implementation 1. Currency formatting differences between regions can break parsing, normalize all monetary values to a single format before sending them to the LLM. 2. Inventory updates might race if multiple orders arrive simultaneously, implement a queue or locking mechanism to prevent overselling. ## Reference implementation https://n8n.io/workflows/3942 (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 Google Sheets?
Yes. Google Sheets is only the example spreadsheet in this recipe. The same flow works with Airtable, Baserow and Excel. 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
Built for founders and execs who need operations handled without hiring for it.
Ops-IT teams triaging their own internal requests get the same pattern, different queue.
