Scan-to-invoice miracle tool! Kailing Technology helps restaurants/hotels complete invoicing in 3 seconds, customer satisfaction soars

Published: 2025-07-23 16:42


At the front desk of restaurants and hotels, it is common to see customers waiting in long lines for invoices. Cashiers repeatedly verify header information, manually enter tax numbers, and retry failed email sends… Issuing a single invoice often takes 10 minutes. During peak hours, the line grows longer and longer, customers frequently check their watches, and their brows furrow tighter and tighter.

After the rollout of fully digitalized e-invoices, although the paper printing step is eliminated, issues such as repeated binding by invoicing staff, email delivery failures, missing SMS notifications, and frequent system logouts have instead made the invoicing process more complex, with customer complaint rates remaining high.


I. Kailing Technology's technical invoicing solution reshapes the entire invoicing process

Kailing Technology delves into industry pain points and, for merchants of different scales and equipment conditions, launches flexible invoicing solutions covering the full-chain closed loop from scanning to delivery, making "instant invoicing" a standard service:

1. Fixed table card code: an efficient model with zero device investment

Merchants place a fixed QR code table sign at the checkout counter, and customers scan the code to self-fill the title and mobile number; the cashier enters the amount with one click on the computer to trigger invoicing. This method completely eliminates the cumbersome process of manually entering titles and prevents the embarrassment of incorrectly entering tax numbers and names, making it especially suitable for high-frequency invoicing scenarios such as fast food and coffee shops.

2. Mobile/PC dual-end invoicing: flexibly adapts to all kinds of merchants

- Mobile invoicing on the go: cashiers use their mobile phone to enter the "invoicing workspace," enter the amount to generate a QR code, and customers scan it to complete their information, completing invoicing anytime and anywhere without computer equipment;

- Computer + receipt printing: the system generates a receipt containing an invoicing code, customers scan the code to fill in information themselves, and existing printers can be used, saving hardware costs.

3. Seamless ERP integration: the ultimate form of fully automated invoicing

The system directly connects to the hotel ERP or restaurant cashier system. When an order is generated, an invoicing QR code is automatically appended to the bill. When customers scan the code, the amount is already locked, and they only need to fill in the title. The backend automatically triggers invoicing and pushes it to email or SMS. With zero manual intervention throughout, it truly achieves "invoice upon checkout."

4. Contactless self-service invoicing: easy processing even after leaving the venue

The customer scans the QR code on the bill or clicks the SMS link and fills in the title information on their mobile phone without staying at the front desk. The validity period of the invoicing link can be set freely. Customers can do this after leaving the meal or returning to their room, completely relieving congestion pressure at the cashier counter.


II. Core advantages: triple leap in efficiency, experience, and compliance

No waiting:Completely eliminate traditional invoicing queues and paper-based filling steps, making the invoicing process fully online.

Precise and error-free:The system automatically identifies associated information, greatly reducing the probability of invoice voiding caused by manual entry errors.

Green and environmentally friendly:Comprehensively promote the adoption of e-invoices, significantly reducing paper consumption and carbon emissions.

The leap in invoicing efficiency has brought significant business value improvements:

- Customer satisfaction significantly improved: Merchant feedback shows that complaints caused by the invoicing process dropped by more than 85%, and satisfaction increased by an average of 30%+.

- Front desk pressure drops sharply: according to calculations by a well-known deployed restaurant chain, invoicing time fell from an average of 10 minutes per person to almost zero, saving more than 150 working hours per store per month.

- Invoicing costs drop sharply: expenditures on labor, printing consumables, and other items are greatly reduced, with reductions generally reaching 60%-80%.

- Efficiency transformation drives experience upgrade: Freeing the front desk from cumbersome invoicing so they can focus more on enhancing the core value of customer service.
