Your adoption rate shows what percentage of your restaurant’s total sales is paid through sunday QR codes. A higher adoption rate means more of your restaurant’s sales are being processed through sunday’s QR payment experience.
How is the adoption rate calculated?
The adoption rate is calculated using the value of payments made through sunday QR codes, not the number of payments.
Formula: Adoption rate = Payments made through sunday QR codes ÷ Total restaurant turnover × 100
Your total turnover includes sales paid through sunday, as well as sales paid through other methods such as cash, card terminals, or other payment solutions.
Example: If your restaurant processes $10,000 in total sales during a given period and $2,000 is paid through sunday QR codes, your adoption rate is: $2,000 ÷ $10,000 × 100 = 20%
This means that 20% of your restaurant’s sales were paid through sunday QR codes.
The adoption rate is simply the percentage of payments made via QR code compared to your total revenue. The higher this percentage, the more your restaurant benefits from adopting this innovative payment method.
A strong adoption rate can create more opportunities for:
More 5-Star Reviews on Google
Customers who use sunday’s QR code to settle their bill enjoy a smooth and quick experience. After paying, they are prompted to leave a review. Thanks to the simplified and positive payment experience, customers are more likely to share their satisfaction on Google, helping to increase your visibility and strengthen your online reputation. More QR code payments mean more review requests, and thus, more opportunities to earn 5-star reviews.
More Tips
The QR code payment process creates a faster, more self-sufficient experience for your customers, who can choose to leave a tip directly through their phone, often in a more generous way. Due to the ease of use, customers are generally more willing to leave a higher tip, which can result in a significant increase in revenue for your team.
Faster Table Turnover
QR code payments allow your customers to pay their bill whenever they wish, without having to wait for the server to bring the check. This means you can free up tables more quickly for new customers, reducing wait times and increasing the number of covers served during each shift. In other words, you maximize the efficiency of each service, directly boosting your revenue.
Increased Revenue
Finally, a higher adoption rate of QR code payments creates a virtuous cycle. As more customers opt for this payment method, they are more satisfied with the experience and more likely to return, leave positive reviews, and recommend your restaurant. This has a direct effect on your foot traffic, revenue, and overall profitability.
How can you improve your adoption rate?
Make the QR code easy to see
Place QR codes where guests can easily find them, such as on tables, menus, or bills. Make sure QR codes are:
Visible and easy to scan
Clean and undamaged
Not covered by other materials
Available at the point when guests are ready to pay
Make sure your team knows how sunday works
Train your team to explain the payment option clearly and confidently. A simple explanation is often enough: “You can pay your bill anytime by scanning the QR code with your phone.”Make sure new team members receive the same training as the rest of the staff. Staff knowledge and consistency can have a meaningful impact on adoption.
Introduce sunday at the right moment
Guests are most likely to use sunday when they understand what it is and why it may be helpful. Your team can mention sunday:
When guests are seated
When they receive the bill
When they ask how to pay
When they are ready to leave
Avoid making the explanation feel complicated or forced. The goal is to make sunday an easy payment option, not to pressure guests to use it.
Help guests who are using sunday for the first time
Some guests may need help locating or scanning the QR code. Show them where to find it and explain that they can use their phone’s camera to scan it.If a guest cannot complete the payment, follow your restaurant’s usual payment process and report any recurring issue to sunday Support.
FAQ
FAQ
Is adoption based on the number of guests who use sunday?
No. Adoption is based on the value of sales paid through sunday QR codes compared with the restaurant’s total turnover. It is not simply the percentage of guests or transactions using sunday.
Do cash and card payments affect my adoption rate?
Yes. Cash, card terminal, and other payments are included in the restaurant’s total turnover. They increase the denominator of the calculation, while only payments made through sunday QR codes are included in the numerator.
Does a higher adoption rate guarantee more reviews or tips?
No. A higher adoption rate creates more opportunities for guests to see the review and tipping experiences, but results depend on guest behavior, staff service, restaurant setup, and other factors.
Why might my adoption rate change from one period to another?
Adoption can change because of staffing changes, QR code visibility, operational changes, seasonal patterns, restaurant closures, or payment and POS issues. Look at the trend over time and investigate sudden changes.
What if my adoption rate looks incorrect?
If your adoption rate suddenly drops to zero or does not match what you are seeing in the restaurant, first check whether:
The restaurant was open during the period shown.
Guests had access to working QR codes.
New or temporary staff members had been trained.
Payments are appearing correctly in the POS and sunday systems.
There is a known payment or integration issue.
If the information still looks incorrect, contact sunday Support and include the date, location, and examples of the affected payments.
In Summary
A high adoption rate of QR code payments isn’t just a sign of modernity and convenience in your restaurant. It’s a powerful lever to increase your online reviews, boost your tips, and drive more revenue. The more your customers adopt this method, the more benefits you’ll reap in the long run.
