With DealPOS, you can send digital receipts via WhatsApp. There are two available methods for sending sales receipts through WhatsApp:

For more details about the differences, advantages, and disadvantages of each method, please refer to the guides below:

A WhatsApp Business Solution Provider (BSP) is a third-party company that helps businesses access and use the WhatsApp Business Platform (API) without having to manage the entire technical integration directly with Meta.

For example, a business may want to send automated WhatsApp messages such as:

Instead of building the entire integration from scratch, businesses can use a BSP to connect their internal systems with WhatsApp.

One of the WhatsApp Business Solution Providers that can currently be integrated with DealPOS is Twilio.

Twilio is a cloud-based communications platform that allows businesses to integrate communication features such as SMS, WhatsApp messaging, voice calls, and video into their applications or systems.

You can see an example of a digital receipt sent to a customer via WhatsApp using a WhatsApp Business Solution Provider in the image below:

In this architecture:

This means DealPOS does not necessarily need to build a direct integration with Meta. Instead, DealPOS can communicate with Twilio's API, and Twilio handles the communication with WhatsApp.

Twilio provides APIs that allow DealPOS to integrate WhatsApp messaging into its existing backend system without having to build a direct integration with Meta from scratch.

DealPOS can automatically send messages to customers based on specific business events, such as:

This reduces the need for employees to manually send messages to customers.

Twilio provides cloud-based communication infrastructure that can handle a large volume of messages. This makes it easier for DealPOS to support businesses with multiple outlets and a growing number of transactions.

DealPOS can manage automated WhatsApp messaging through its backend integration with Twilio, allowing messages to be triggered by specific events within the application.

DealPOS does not need to independently maintain the entire WhatsApp messaging infrastructure. Twilio handles much of the communication integration and infrastructure management.

Using Twilio introduces additional costs. Depending on the implementation, expenses may include:

These costs may increase as the number of outgoing messages grows.

DealPOS becomes dependent on Twilio to deliver automated WhatsApp messages.

If Twilio experiences service disruptions, API errors, or technical issues, DealPOS may temporarily be unable to send messages through the integration.

Automated WhatsApp messages must comply with Meta's WhatsApp Business Platform policies.

For example:

Failure to comply with these policies may result in message restrictions or account limitations.

Twilio simplifies WhatsApp integration and reduces infrastructure management responsibilities for DealPOS. However, it also introduces additional costs, third-party dependencies, and technical considerations.

The decision to use Twilio should ultimately depend on the balance between development convenience, operational costs, system reliability, and long-term flexibility.

The WhatsApp Signed Device method means that you need to sign in to WhatsApp using the device you use for sales transactions at the POS. This can be done through a web browser or an installed desktop application.

You can see an example of a digital receipt sent to a customer via WhatsApp via signed device in the image below:

This method uses WhatsApp's existing Web or Desktop session. DealPOS prepares the recipient and message template, but the user must manually click Send to deliver the receipt.

DealPOS does not need to integrate with third-party providers such as Twilio or other WhatsApp Business Solution Providers (BSPs).

Businesses do not need to pay additional Twilio or BSP messaging fees. They can use their existing WhatsApp account, subject to WhatsApp's applicable terms and usage limits.

The integration is relatively simple because DealPOS only needs to prepare the recipient's phone number and message template, then redirect the user to WhatsApp.

Users can send receipts using their existing WhatsApp account without registering a separate API-based WhatsApp Business integration.

Users can review the recipient and message content before clicking the Send button. This provides an additional opportunity to verify the information before sending.

Unlike API-based messaging, users must manually click the Send button in WhatsApp for every receipt. This means the process cannot be fully automated from DealPOS.

Users must log in to WhatsApp through a Web Browser or Desktop App before sending receipts. If the session expires or the device becomes disconnected, users may need to log in again.

Since users must manually send each receipt, this method may become less efficient for businesses that process a large number of transactions.

WhatsApp has a limit on the number of devices that can be linked to a single WhatsApp account. This can become a limitation for businesses where multiple cashiers operate using different devices or POS terminals.

For example:

The WhatsApp Signed Device method offers a relatively simple and cost-effective approach to sending digital receipts. It eliminates the need for additional BSP integration and messaging provider fees.

However, its main limitation is the dependency on manual user interaction and an active WhatsApp session.

For businesses that prioritize simplicity and minimal additional costs, this method can be a practical choice. For businesses that require large-scale, fully automated messaging, an API-based solution may be more suitable.
