Essential guide for IT and Operations leaders looking to integrate VTEX + ERP without friction, ensuring accuracy in catalog, pricing, and inventory.
Multi-country and multi-store retail in Latin America operates in a uniquely complex environment: high transactional volumes, fiscal and logistics variations per region, and the urgent need to deliver seamless omnichannel experiences. To face these challenges, adopting modern ecommerce platforms is essential.
VTEX stands out as a Composable and Complete solution designed for agility. However, the promise of composability only becomes real when seamless integration is achieved with the ERP (Enterprise Resource Planning), the heart of the operation.
This is where Weavee becomes the crucial link. We provide the System Integrator and Integrated Management System required to connect VTEX with core systems like SAP, Oracle NetSuite, or Dynamics — without code and without errors.
Ready to eliminate the risk and friction in your integration?
Historically, large-scale retailers relied on monolithic architectures that limited agility and innovation. Composable Commerce — a modular approach based on decoupled microservices and APIs — is the modern answer.
VTEX offers Pragmatic Composability, allowing merchants to leverage native services for core needs while composing best-of-breed external solutions where competitive advantage is required.
An ERP is the core back-office software that manages essential parts of operations, including Catalog, Pricing, Logistics, and Orders. Attempting to merge the flexibility of VTEX composable architecture with an ERP through patching or point-to-point development creates high total cost of ownership (TCO) and rigidity — defeating the purpose of composability.
Integration between ERP and VTEX is implemented using APIs from each module, which requires an advanced integration solution like Weavee, acting as a hub for data transformation, orchestration, and monitoring.
For LATAM retailers, real-time accuracy and synchronization of data are non-negotiable. The most important data flows must focus on four pillars: Catalog, Pricing, Orders/OMS, and Checkout.
Catalog management includes category tree, brands, products, SKUs, and specifications. The ERP or PIM (Product Information Manager) is typically the source of truth for this data.
Integration uses the VTEX Catalog API. A robust flow must ensure that any update — from a new SKU to a change in description — propagates efficiently to VTEX.
Pricing in LATAM retail is particularly complex due to different contexts such as customer groups, regions, or channels (Online Sales vs. Physical Stores).
VTEX enables fixed prices or modification across contexts via trade policies. Synchronization of pricing is performed through the Pricing API.
For B2B businesses (fully supported by VTEX), the platform allows grouping users into organizations and applying specific prices; the B2B Quotes & Carts app enables price negotiation.
It is crucial that the integration flow can handle VTEX trade policy complexity in order to reflect the commercial strategy defined in the ERP.
VTEX includes its own OMS (Order Management System), but the ERP must integrate through the Orders API to receive order events and manage processing.
Critical OMS integration flows must prioritize efficiency:
External software (ERP) can receive order events through two methods: Feed (reading an event queue using Feed v3 documented by VTEX) or Hook (automatic notifications) Using Feed v3 is vital to avoid constant polling (repetitive, inefficient requests).
After receiving an event, the ERP processes the order (change, cancel, invoice) and returns the result to the VTEX OMS. Proper orchestration and mapping of statuses between platforms is essential for the omnichannel experience.
The VTEX Checkout module coordinates Catalog, Pricing, Promotions, Logistics, and Payment data to complete the purchase. It uses the Checkout API to allow custom solutions.
Before the order is placed, checkout must be able to perform cart simulations (orderForm is the object representing the cart, implicitly used by the Checkout API) to ensure that inventory and prices consulted are accurate and available. Low latency at this stage is critical.
A successful integration — especially in high-volume retail (e.g. Black Friday) — requires a structured process focused on operational resilience.
1. Discovery & Planning: Define which parts of operations will be integrated and how data will be mapped between VTEX and ERP.
2. Incremental Delivery: Weavee’s composable architecture allows adding, replacing, and adapting tech components quickly, enabling phased delivery.
3. Observability Once live, real-time monitoring is crucial. Weavee oversees every data exchange, ensuring ecommerce operations remain optimized.
4. Hardening (retries/queues): The system must be resilient to temporary ERP or network failures. Weavee’s Microsoft Azure-based platform provides scalability and security, and its design enables queue handling and automatic retries to prevent event or inventory loss (implicit value of Weavee’s hub architecture).
CIOs and CTOs need clear metrics to measure integration health and operational resilience.
Weavee offers custom alerts and instant reports to supervise these metrics. To ensure secure operations, we use advanced protocols and enterprise-grade encryption, complying with international standards such as ISO 27001, SOC 2, and FedRAMP.
