How to Integrate WhatsApp with SAP, TOTVS, and Oracle Without Replacing Your ERP
WhatsApp integration with SAP, TOTVS, and Oracle: technical models, timelines, case studies, and how to connect chat to ERP without replacing systems.
One of the main objections that managers at mid-size and enterprise companies raise when the topic is corporate WhatsApp is: “but how does this integrate with our system?”
It is a legitimate objection. Companies that invested years and millions in systems such as SAP, TOTVS, or Oracle will not (and should not) abandon those systems to adopt a new customer service and sales channel. The question is not replacing the ERP. The question is connecting WhatsApp to it.
The good news is that this integration exists, works, and is already in production at companies across different segments in Brazil.
Why WhatsApp and ERP Integration Matters
Without integration, corporate WhatsApp becomes an isolated channel: agents respond to messages manually, consult the system on another screen, copy and paste information, and make manual entries in the ERP. It is slow, error-prone, and does not scale.
With integration, WhatsApp becomes an extension of the ERP: inventory inquiries, order status, duplicate documents, scheduling, and even sales happen automatically, with data flowing in real time between the chat and the management system.
For the customer, the experience improves: they receive immediate and accurate answers. For the company, operational cost drops and reliability increases.
What Can Be Integrated
Integration between WhatsApp and ERP is not a one-size-fits-all solution: it can cover different processes, depending on each company’s needs:
Order and status inquiries The customer sends a message asking about their order status. AI queries the ERP in real time and responds with updated information (order number, status, delivery estimate) without human intervention.
Inventory and availability inquiries External sales reps or B2B customers check product availability directly through WhatsApp. The system queries the ERP and responds in seconds.
Duplicate document issuance Invoices, tax documents, pay slips, statements: AI retrieves the document from the ERP and sends it to the customer in the chat.
Order registration Orders placed through WhatsApp are automatically registered in the ERP, with no manual data entry and all information needed for processing.
Registration updates Customers or suppliers update registration data through WhatsApp, and the information is automatically synchronized in the ERP.
Proactive notifications The ERP automatically sends WhatsApp messages when relevant events occur: order approved, payment confirmed, invoice issued, due date approaching.
Financial inquiries for suppliers Suppliers check the status of open invoices, scheduled payment dates, and transaction history directly through WhatsApp, without needing to call or email finance.
How Integration Works Technically
There are two main integration models between WhatsApp and ERP:
Model A: REST API integration
The most robust model, recommended for real-time data. The WhatsApp platform directly consumes ERP APIs to query and register information.
Advantages:
- Real-time data
- Greater security and control
- Scalability
- Lower need for additional infrastructure
Requirement: the ERP must expose documented APIs for the desired features. SAP, TOTVS, and Oracle have APIs available for their cloud versions and modern on-premise versions.
Model B: Local synchronizer integration
Recommended for ERPs with external access limitations or for more agile implementations. The company provides files (CSV/JSON) or access to database replicas, and the WhatsApp platform connector performs periodic read and synchronization.
Advantages:
- Faster implementation
- Works with older ERPs
- Lower dependency on ERP-side development
Limitation: data is not absolutely real-time; there is a synchronization interval (usually from minutes to hours).
SAP Integration: TeaserMe’s Pioneering Work
SAP is the ERP most used by large corporations worldwide. In Brazil, manufacturing, logistics, retail, and services companies depend on SAP for their most critical processes.
TeaserMe was a pioneer in Brazil in WhatsApp integration with SAP. This means companies using SAP can connect their processes to WhatsApp without changing systems, without complex integration projects, and without risk to data integrity.
In practice, a customer can send a message asking about an order status and receive, in seconds, a response with data directly from SAP, including order number, status, invoice, and delivery estimate.
TOTVS Integration
TOTVS is Brazil’s largest ERP by number of clients and is present in companies of all sizes and segments. TeaserMe’s integration with TOTVS allows companies to connect their service, sales, and communication processes to the ERP without changing existing operations.
Common use cases in TOTVS + WhatsApp integration:
- Order inquiries by customers and sales reps
- Automatic sending of invoices and tax documents
- Supplier service about payments
- Credit and order approval notifications
- Employee portal via WhatsApp for HR
Oracle Integration
Oracle ERP is widely used by mid-size and enterprise companies, especially in industrial and services sectors. Integration via Oracle REST APIs allows connecting customer service and sales flows on WhatsApp with financial, operational, and supply chain data in real time.
Distribusion Integration
For the mobility and interstate transportation sector, Distribusion is a global ticket distribution platform present in more than 90 countries. TeaserMe has integration with Distribusion, allowing bus terminals and transportation companies that use the platform to also sell interstate tickets through WhatsApp.
The Real Challenge: It Is Not Technical, It Is Process
Companies that have gone through WhatsApp and ERP integration projects report that the biggest challenge is not the technical part: it is process mapping.
Before connecting the systems, it is necessary to answer:
- Which processes make the most sense to migrate to WhatsApp?
- Which information do customers/suppliers need to access most frequently?
- Which business rules need to be replicated in the WhatsApp flow?
- How is the exception process (cases AI does not resolve) handled?
A good implementation partner does not just connect the systems. They help map these processes and define the right scope to maximize return.
How Long Implementation Takes
Implementation timeline varies according to scope and the chosen integration model:
| Scope | Model A (REST API) | Model B (Synchronizer) |
|---|---|---|
| Basic information inquiry | 2-3 weeks | 1-2 weeks |
| Full service automation | 4-6 weeks | 3-4 weeks |
| Sales with integrated checkout | 6-10 weeks | 4-6 weeks |
| Full portal (suppliers + customers) | 8-12 weeks | 6-8 weeks |
These timelines assume the ERP already has APIs available and scope is well defined. Projects with greater complexity or additional customizations may have longer timelines.
What to Evaluate When Choosing an Integration Partner
Proven experience with the ERP It is not enough for the partner to say they integrate with SAP or TOTVS; require references and case studies from real implementations.
Meta Tech Provider credential WhatsApp integration must be done via the official API. Partners without Meta Tech Provider credential operate in a risk zone.
Post-implementation support Integration must be maintained over time: ERP updates, API changes, new features. The partner must have ongoing support structure.
Security and LGPD compliance Customer and supplier data moving between WhatsApp and ERP must be protected. Verify the partner’s security policies and LGPD compliance.
Case: Hyva Group
Hyva Group, a global company in hydraulic solutions for commercial vehicles with operations in Brazil, identified an opportunity to reduce the volume of manual calls to finance from suppliers and customers asking about open invoices, payment status, and duplicate documents.
TeaserMe developed a Unified Self-Service Portal integrated with Hyva’s ERPs (Infor Cloud, SAI, and TOTVS), allowing suppliers and customers to check their financial information directly through WhatsApp, without needing to call or send email.
The result is a drastic reduction in manual calls to finance and an improved experience for suppliers and customers who previously had to wait for a response to get simple information.
Conclusion
Integrating WhatsApp with SAP, TOTVS, Oracle, or any other ERP is not a science fiction project: it is a reality in production at Brazilian companies of different sizes and segments.
The starting point is not technology. It is the question: which processes, if resolved automatically through WhatsApp, would bring the most value to customers and the most efficiency to operations?
With that answer in hand, technical integration is a consequence.
