What is a Restaurant POS System

Basic Concept

A restaurant POS system is a sales management system used in restaurants and cafés. In addition to traditional cash register functions, it integrates features like order management, table management, inventory management, and sales analysis.

Difference from traditional cash register:

• Traditional cash register: Payment function only, order management with paper tickets
• Modern POS: Payment + order management + inventory management + sales analysis + accounting integration

Main features:

1. Order Management: Order reception and management by table
2. Payment Processing: Supports various payment methods (cash, card, QR payment, etc.)
3. Table Management: Table availability management, reservation management
4. Inventory Management: Ingredient and raw material inventory management, ordering management
5. Sales Reports: Daily/monthly sales reports, product/time period analysis
6. Accounting Integration: Automatic integration with accounting software (freee, Money Forward, etc.)
7. Mobile Ordering: Self-ordering using QR codes

Why It's Important

Business Perspective:

• Work Efficiency: Automation of order and inventory management can reduce work time by 40-60 hours/month
• Sales Increase: Mobile ordering implementation has shown 20-30% sales increase through reduced wait times
• Cost Reduction: Automation of accounting work reduces accounting work time by 30-50%
• Customer Satisfaction Improvement: Reduction of order errors and wait times

Technical Perspective:

• Real-time Management: Real-time tracking of inventory and sales status
• Data Analysis: Analyze sales data to improve menus and optimize inventory
• Multi-store Management: Cloud-based systems can centrally manage multiple stores

Data:

• Restaurant POS system adoption rate: Approximately 70% (Small and Medium Enterprise Agency survey, 2025)
• POS system implementation reduces work time by average 40% (Industry survey, 2024)

Best Practices

Practice 1: Always Try Free Trial

Description: You won't know ease of use or feature practicality without actually using it. Try free trial for at least 1 week and have multiple staff use it.

Example: Restaurant A tried free trials from 3 companies and selected Seisei as easiest to use. Smooth operation after implementation.

Effect: Prevents post-implementation dissatisfaction, allows selection of high-satisfaction system.

---

Practice 2: Consider POS and Accounting Integration

Description: Integrated POS and accounting systems (like Seisei) require no integration fees and enable automatic journal entries. Separate system integration may incur ¥5,000-10,000/month additional fees and data migration hassle.

Example: Café B initially implemented POS and freee separately, costing ¥8,000/month in integration fees and requiring manual data migration. After switching to Seisei, no integration fees and 15 hours/month work time reduction.

Effect: Cost reduction, work time reduction, prevention of data errors.

---

Practice 3: Consider Mobile Ordering Implementation

Description: Mobile ordering (QR code ordering) can reduce wait times and increase sales. Especially effective for cafés and restaurants crowded during lunch.

Example: Café C implemented mobile ordering, reducing wait time 30% and increasing sales 20%.

Effect: Customer satisfaction improvement, sales increase, staff burden reduction.

---

Practice 4: Add Features Gradually

Description: Don't try to use all features from start. Begin with basic features and add optional features as you get used to it. Implementing many features at once can cause staff confusion and operation errors.

Example: Restaurant D initially used only order management and payment features, added inventory management after 3 months, and mobile ordering after 6 months.

Effect: Smooth implementation, staff proficiency, gradual efficiency improvement.

---

Practice 5: Analyze Data Regularly

Description: Utilize POS system sales reports to analyze sales by product and time period. Use data to improve menus and optimize business hours.

Example: Izakaya E discovered through sales reports that 20-22:00 on weekdays had highest sales. Increased staff during this time and increased sales 15%.

Effect: Data-driven business decisions, sales increase, cost optimization.

---
