Claude Skills for Restaurant POS System Development

Building a restaurant point-of-sale system requires handling orders, inventory, payments, and reporting. Claude Code skills streamline this development by automating document generation, testing, data management, and reporting workflows. This guide covers practical applications for developers building restaurant POS solutions. For a broader look at how skills handle domain-specific automation, see the use cases hub.

Order Management with Spreadsheet Automation

Restaurant POS systems generate substantial operational data: daily sales, inventory counts, employee shifts, and customer orders. The xlsx skill enables rapid data analysis and report generation without manual spreadsheet manipulation.

# Example: Generate daily sales report from order data
import pandas as pd
from openpyxl import Workbook

def generate_daily_report(orders: list[dict], output_path: str):
    wb = Workbook()
    ws = wb.active
    ws.title = "Daily Sales"
    
    # Headers
    ws.append(["Order ID", "Time", "Items", "Total", "Payment Method"])
    
    for order in orders:
        ws.append([
            order["id"],
            order["timestamp"],
            ", ".join(order["items"]),
            order["total"],
            order["payment"]
        ])
    
    wb.save(output_path)

Use the xlsx skill to automate recurring reports:

/xlsx create weekly-inventory.xlsx: Sheet1=inventory_data, Sheet2=reorder_suggestions, formulas for stock_alert column
/xlsx analyze sales-data.csv: calculate daily revenue, top 10 items, peak hours, group by payment method

Invoice and Receipt Generation with PDF Skills

Every transaction in a restaurant POS requires documentation. The pdf skill handles invoice generation, receipt formatting, and batch processing of daily transactions.

# Example: Generate receipt PDF for restaurant orders
from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvas

def generate_receipt(order: dict, filename: str):
    c = canvas.Canvas(filename, pagesize=letter)
    y = 750
    
    c.setFont("Helvetica-Bold", 16)
    c.drawString(50, y, "Restaurant Receipt")
    y -= 30
    
    c.setFont("Helvetica", 10)
    c.drawString(50, y, f"Order #: {order['order_id']}")
    y -= 15
    c.drawString(50, y, f"Date: {order['timestamp']}")
    y -= 30
    
    for item in order["items"]:
        c.drawString(50, y, f"{item['name']} x{item['qty']}")
        c.drawRightString(550, y, f"${item['price'] * item['qty']:.2f}")
        y -= 15
    
    y -= 10
    c.line(50, y, 550, y)
    y -= 20
    
    c.setFont("Helvetica-Bold", 12)
    c.drawRightString(550, y, f"Total: ${order['total']:.2f}")
    
    c.save()

Practical PDF commands for POS development:

/pdf merge all receipts in ./day-2026-03-14/*.pdf into daily-report.pdf
/pdf extract transaction totals from ./invoices/march-2026.pdf: create summary table
/pdf create receipt.pdf: Order #1234, Table 5, 2x Burger, 1x Fries, Total $24.50

Testing POS Workflows with TDD and Web Testing

Restaurant POS systems involve complex state management: order creation, payment processing, inventory deduction, and kitchen ticket routing. The tdd skill and webapp-testing skill ensure reliable POS behavior.

# Example: Test order state transitions
import pytest
from pos.order import Order
from pos.payment import PaymentProcessor

class TestOrderWorkflow:
    def test_order_creation(self):
        order = Order(table_id=5)
        assert order.status == "open"
        assert order.items == []
    
    def test_add_items_updates_total(self):
        order = Order(table_id=5)
        order.add_item({"name": "Burger", "price": 12.00, "qty": 2})
        assert order.total == 24.00
    
    def test_payment_completes_order(self):
        order = Order(table_id=5)
        order.add_item({"name": "Salad", "price": 8.00, "qty": 1})
        
        processor = PaymentProcessor()
        result = processor.process_payment(order, method="card")
        
        assert result["status"] == "completed"
        assert order.status == "paid"

Test POS workflows with Claude:

/tdd write pytest tests for Order class: test_add_item, test_remove_item, test_apply_discount, test_checkout
/tdd given this failing test, implement the PaymentProcessor.process_cash() method: [paste test]
/webapp-testing verify POS frontend: add item to order, apply 10% discount, process payment, verify receipt shows correct total

Restaurant POS systems require dynamic menu management: items, prices, modifiers, availability, and category organization. Combine spreadsheet automation with code generation for structured menu data handling.

# Example: Menu item with modifiers
MENU_ITEM_SCHEMA = {
    "id": "burger-classic",
    "name": "Classic Burger",
    "price": 12.99,
    "category": "mains",
    "modifiers": {
        "cooking_temp": ["rare", "medium-rare", "medium", "medium-well", "well-done"],
        "extras": [
            {"name": "Add Cheese", "price": 1.50},
            {"name": "Add Bacon", "price": 2.00},
            {"name": "Add Avocado", "price": 2.50}
        ],
        "sides": ["fries", "salad", "onion rings"]
    },
    "available": True,
    "preparation_time_minutes": 15
}

Use Claude skills for menu operations:

/xlsx import menu-data.csv into menu.json: transform prices to cents, validate modifier arrays, output structured JSON
/xlsx create menu-pricing.xlsx: Sheet1=items, Sheet2=modifiers, Sheet3=categories, VLOOKUP for price calculations

Inventory Tracking Integration

Restaurant POS systems connect closely with inventory management. Track ingredient usage, trigger reorder alerts, and calculate food costs using data automation skills.

/xlsx analyze inventory.csv: calculate usage per menu item, identify low-stock ingredients, suggest reorder quantities
/xlsx create food-cost-report.xlsx: link to sales data, calculate actual food cost percentage per day, highlight variance over 5%

Why These Skills Matter for POS Development

Restaurant POS development involves multiple data types: orders, payments, menus, inventory, and reports. Claude skills handle the document and data automation that would otherwise consume significant development time.

The spreadsheet skill transforms raw transaction data into actionable insights. The PDF skill generates the receipts and invoices every restaurant needs. Testing skills ensure the complex state transitions in order processing work correctly.

Start with these skills when building restaurant POS solutions. They handle the operational complexity so you can focus on core POS functionality.
