SMS payment : how it works
SMS payment simplifies customer transactions by combining billing information and the payment link on a single screen. This solution saves time and offers a smoother experience for both the business and the customer.
Here are the main steps for payment by SMS :
1- Payment request via SMS
An SMS is sent to the customer’s phone voicemail. This message contains a short message with the payment information (invoice reference, amount, etc.) as well as a secure payment link.
2- Access to the payment page
The customer clicks on the link to access an online payment interface. This displays the amount due, the invoice reference, and the company’s contact details.
3- Choosing the payment method
The customer can choose their preferred payment method : bank card, bank transfer or payment initiation (which redirects directly to the bank).
4- Payment validation
The customer makes the payment through a secure interface.
5- Confirmation and receipt of receipt
Once the payment is validated, a confirmation SMS is sent. The customer receives a transaction receipt, while the company is immediately notified of the payment.
This process marks a shift towards more direct and instant billing methods, in line with customers’ mobile habits.
Thanks to SMS payment, customers can pay their bills more easily and quickly, without going through complex steps.
What are the advantages of SMS payment for businesses ?
For businesses, and particularly in B2B, SMS payment allows for better receivables management, a reduction in DSO and an overall improvement in customer relations.
Here are the advantages to consider when paying by SMS.
Reduction of payment delays
SMS payment allows businesses to request payment from customers through a personalized channel, enabling them to pay quickly and easily. This method accelerates cash flow and helps reduce unpaid invoices and delays. Payment terms remain a major challenge for businesses that rely on timely payments.
Simplicity and practicality for customers
Paying by SMS allows customers to settle their bills anytime, anywhere. This convenience increases the rate of prompt payments and reduces friction in B2B transactions.
Reduction in unpaid invoices
Thanks to its speed of execution, SMS payment significantly reduces the risk of non-payment and payment delays. Furthermore, automatic SMS reminders enhance efficiency and ensure rigorous monitoring of receivables.
Improving customer relations
A clear, fast, and secure payment process strengthens trust and satisfaction among business partners. Companies that integrate SMS payments are perceived as innovative and customer-centric, which fosters loyalty.
Automated tracking and real-time notification
Each SMS payment generates an instant notification for the company, simplifying accounting. This automation saves time on administrative tasks and reduces errors associated with manual data entry.
Adaptability to different B2B scenarios
SMS payment integrates seamlessly with all types of billing : one-off services, subscriptions, or recurring orders. This flexibility makes it particularly relevant for businesses looking to modernize their payment methods while maintaining a close relationship with their customers.
Payment by SMS : security at the heart of the process
