Let’s start with understanding what SMS billing is.

What is SMS Billing?

In simple terms, SMS billing involves sending an SMS to your customers, allowing them to pay directly through that message. So, when you use SMS billing, you and your customers don’t need to deal with back-and-forth emails or complex website navigation. A simple text message can let you and your customers complete the transaction, and that can also be done with just a few clicks.

A Quick Comparison: SMS Invoicing Vs. SMS Billing Vs. Transactional SMS

It is important that you understand that SMS billing, transactional SMS, and SMS invoicing are different. Here is a quick comparison between all of them, which will clear your confusion. All three use text messages to communicate with customers. However, their purpose, functionality, and user experience are quite different.

In short, if you want to let your customers pay via simple replies, then use SMS billing. If you want to send a detailed invoice, use SMS invoicing. And, if you’re going to send a confirmation or alert only, use a transactional SMS.

Now that you understand the difference between these three, let’s understand how SMS billing works.

How SMS Billing Works: Step-by-Step

Here is a quick breakdown of how the text payment process works for businesses.

Before any business collects bill payments via SMS, they need to set up Text-to-Pay functionality. For that, they need a registered phone number for sending business SMS and an SMS billing system that offers a feature such as Text-to-Pay.

1. The customer opt-in to receive SMS communication.
2. Businesses send an SMS with the secure payment link to customer’s mobile phone. For example, “Hey Alex, your membership fee of $30 is due. Click on this to pay now.
3. The customer agrees to the terms for SMS billing. The customer clicks on that link or replies with “YES”, and completes the transaction. Typically, the SMS billing platform processes payments via the stored card or mobile wallet. If not, the user must enter their payment details.
4.  Now, the payment processor handles the transaction and informs the business.
5. Finally, the customer receives a confirmation text stating that they have made a payment.

Usually, the business receives the payment within a day or two. In short, pay by text message enables quick, real-time, and secure transactions and that too without apps, passwords, or complications.
