En un mundo digital cada vez más interconectado, donde la unificación de los procesos en línea y fuera de línea se ha convertido en un imperativo estratégico, las empresas reconocen la necesidad de integrar el sistema de planificación de recursos empresariales (ERP) y los sistemas de comercio electrónico. La implementación de un ERP para las empresas de comercio electrónico ayuda a optimizar la gestión del inventario, el cumplimiento de los pedidos, la atención al cliente y la eficiencia operativa en general. Sin embargo, si bien la forma tradicional de integrar estas soluciones implicaba crear conexiones punto a punto con código personalizado, este método lleva mucho tiempo y carece de escalabilidad. Esta es la razón por la que los integradores de sistemas, las agencias y los desarrolladores modernos están recurriendo ahora a las plataformas de integración de última generación o, más específicamente, a la «plataforma de integración como servicio (iPaaS)» basada en API, para permitir una integración escalable del ERP y el comercio electrónico.

The strategic benefits of an ERP and e-commerce integration


The "ERP and e-commerce integration" is one of the most common and crucial e-commerce integrations that businesses have been employing developers to build and orchestrate since the advent of the digital age. The need for implementing an ERP for e-commerce emerged from the operational inefficiencies of manual data entry, delays in order processing, difficulties in updating inventories accurately, and many other issues that resulted from these two systems being disconnected.

As a result, businesses soon realized the strategic potential of an ERP and e-commerce integration, wherein an ERP for e-commerce yielded several benefits, such as:

Efficient Data Management: Integrating data between ERP and e-commerce systems helps eliminate the need for manual data entry and reduces the risk of errors and inconsistencies.

Automated processes: Building workflows that span both ERP and e-commerce can help automate processes that can lead to increased productivity and reduced operational costs.

Holistic Business Insights: Businesses can combine and analyze customer data, product info, financial details, logistical information, and more, enabling informed decision-making.

Optimized stock levels: An ERP and e-commerce integration allows businesses to maintain optimal stock levels and ensure products are always available when needed, minimizing stockouts or overstock situations.

Improved Customer Experience: Provide customers with real-time information on inventory, order status, and shipping, leading to enhanced satisfaction and loyalty.

Integrating e-commerce and ERP: best method

Over the years, agencies, system integrators, and developers have explored several methods and solutions to implement an ERP and e-commerce integration, from building custom-code integrations to using middleware solutions, all the way to now implementing API-driven integration platforms. Let's explore all these integration methods to discover what is the best method for ERP to e-commerce integration:

The limitations of point-to-point integration: custom code

Traditionally, developers have helped businesses build point-to-point ERP and e-commerce integrations with custom code. However, creating custom-coded integrations is expensive, time-consuming, and lacks scalability. For instance, if businesses wish to integrate more systems on top of the existing ERP and e-commerce integration, such as a CRM system or any of the latest SaaS (Software as Service) solutions or cloud apps, doing so with custom code is challenging, and requires extensive troubleshooting.

Moreover, governing and managing these integrations requires senior developers or professionals with coding expertise, which makes maintenance of the ERP and e-commerce integration even more expensive. This is why agencies and systems integrators resorted to middleware solutions to build integrations.

Traditional middleware solutions: ESB solutions

Among the many different types of middleware solutions for integrating systems like ERP for e-commerce, the Enterprise Service Bus (ESB) emerged as one of the first early full-fledged integration platforms. Designed for enterprise-level integration, ESB solutions are traditionally on-premises systems, which functioned as centralized communication hubs that helped enterprises integrate several disparate systems, apps, and data sources, and they all also helped facilitate data exchange between legacy ERP and e-commerce systems.

Unlike the point-to-point integration approach with custom code, ESB systems provide a more flexible architecture that allows system integrators to create easier modifications and add new integrations without disrupting the entire system. However, the plethora of new cloud apps, SaaS solutions, or e-commerce features that businesses now need to integrate in order to stay competitive, makes it challenging even for ESB solutions to keep up.

As a result, the recent introduction of API-led connectivity that powers cloud-based integration, has led developers and integrators to start using the "integration Platform as a Service (iPaaS)".

Next-gen integration platform: The iPaaS

The iPaaS (integration Platform as a Service) is a cloud-based, low-code or no-code middleware. It helps create, manage, and monitor integrations between several new SaaS solutions, cloud apps, data sources, and even legacy on-premises systems, harnessing the power of APIs.

Designed to enable real-time exchange and synchronization between integrated systems, iPaaS solutions also provide a rich library of connectors that facilitate faster and seamless integrations between popular systems, such as ERP for e-commerce integrations, but also other applications such as CRM, PIM, OMS, payment gateways, marketplaces, marketing automation software, and more. Advanced iPaaS solutions like Alumio provide flexible data transformation tools and workflow builders that help facilitate process automation, which helps system integrators customize integrations limitlessly.

Most importantly, while ERP systems are designed to integrate internal processes such as operations, logistics, and finance, they aren't built to integrate seamlessly with e-commerce applications. Thus, when integrating e-commerce solutions and ERP, best practice dictates that compared to other integration methods, the iPaaS (integration Platform as a Service) provides developers with flexible tools and architecture needed to build an effective and scalable ERP and e-commerce integration.

How the iPaaS helps build flexible ERP and e-commerce integration

Unlike traditional integration methods, the iPaaS (integration Platform as a Service) offers better customizability, scalability, and faster deployment, making it the ideal choice for building an ERP and e-commerce integration.

Cloud-based flexibility

As a cloud-based solution, it provides system integrators with a visual web interface to develop, govern, and orchestrate data flows and automate processes between the integrated ERP and e-commerce platforms. Advanced iPaaS solutions like Alumio even enable hybrid cloud integration, wherein even on-premises ERP systems like SAP ECC can be integrated with Shopify, a cloud-based e-commerce platform, via the cloud.

Scalable growth

The iPaaS provides a scalable infrastructure that can effortlessly accommodate the evolving needs of businesses, ensuring that integration remains robust as data volumes and transaction loads increase, which is crucial for e-commerce businesses during peak sales.

User-friendly integrations

The user-friendly interfaces and intuitive tools embedded in iPaaS platforms make it accessible to both technical and non-technical users, streamlining the integration process and reducing dependency on specialized IT skills.

Integration interchangebality

The iPaaS also offers the agility and rapid deployment capabilities that businesses need to swiftly adapt to new market trends, enabling businesses to swiftly integrate new applications, features, or customizations to the existing ERP and e-commerce integration, without loss of data integrity.

However, despite all this, building ERP for e-commerce integrations is still challenging, even with an iPaaS solution. Most ERP solutions provide their own set of tools and rules, which requires heavy configuration to successfully integrate them with e-commerce apps. This is why advanced iPaaS solutions like Alumio provide specialized connectors and APIs to facilitate faster and seamless integrations with popular ERP systems.

Building faster ERP for e-commerce integrations with the Alumio ERP API Plugin

Alumio is a low-code, cloud-native iPaaS solution that's designed to facilitate faster ERP and e-commerce integrations. Popular ERP systems like SAP, Microsoft Dynamics 365, and Exact Globe lack essential B2C & D2C API points or B2B ERP software connectivity that is required to integrate them with e-commerce, PIM, CRM, and other apps. Custom building these API points is time-consuming, expensive, and error-prone.

Productizing decades of experience in integrating ERP systems, Alumio has developed unique ERP API Plugins that help install these lacking B2C or D2C API points directly within the ERP systems. Installing these necessary API points with the Alumio ERP API plugin makes it easier to integrate ERP and e-commerce solutions, enabling seamless B2C, D2C, and B2B ERP software connectivity.

Installing the Alumio ERP API plugins help drastically simplify and enhance integrations with the following systems, via the Alumio iPaaS:

PREGUNTAS MÁS FRECUENTES

Integration Platform-ipaas-slider-right
¿Por qué la integración de los sistemas ERP y el comercio electrónico es estratégicamente importante para las empresas modernas?

La integración de ERP y comercio electrónico es estratégicamente importante porque conecta el sistema que gestiona la infraestructura financiera y operativa de la empresa (ERP) con el sistema que genera los ingresos de los clientes (comercio electrónico). Sin esta integración, los pedidos realizados en línea deben ingresarse manualmente en el ERP para su procesamiento, los niveles de inventario en la tienda en línea se desactualizan a medida que cambia el stock del ERP, y la conciliación financiera requiere exportaciones y comparaciones manuales. La integración automatiza esta conexión, lo que hace que las operaciones de comercio electrónico sean escalables, financieramente precisas y operativamente eficientes a medida que aumenta el volumen de pedidos.

Integration Platform-ipaas-slider-right
¿Cuáles son los principales flujos de datos en una integración de ERP y comercio electrónico?

Los principales flujos de datos bidireccionales son: pedidos del comercio electrónico al ERP para el registro financiero, el procesamiento de pedidos y la disminución del inventario; niveles de inventario del ERP al comercio electrónico en tiempo casi real para evitar la sobreventa; datos de productos y precios del ERP al comercio electrónico para mantener la tienda en línea actualizada con los datos maestros del ERP; datos de clientes y cuentas entre el comercio electrónico y el ERP para la gestión de cuentas B2B; y confirmaciones de pedidos y datos de seguimiento del ERP o WMS al comercio electrónico para actualizar el estado de los pedidos de los clientes. Cada flujo requiere lógica de transformación para conciliar el modelo de datos del ERP con el formato API de la plataforma de comercio electrónico.

Integration Platform-ipaas-slider-right
¿Qué hace que la integración de un sistema ERP con el comercio electrónico sea técnicamente compleja?

Los desafíos técnicos son: los modelos de datos ERP son complejos y altamente estructurados (diseñados para la precisión operativa interna, no para el consumo de API externas), muchos sistemas ERP (especialmente SAP ECC) utilizan protocolos de integración heredados (BAPI, IDoc) en lugar de API REST estándar, la transformación de datos entre esquemas ERP y formatos de API de comercio electrónico requiere un trabajo de mapeo significativo, y los cambios en cualquiera de los sistemas (actualización de la versión de ERP, actualización de la plataforma de comercio electrónico) corren el riesgo de romper la integración. Estos desafíos hacen que la integración ERP-comercio electrónico sea una de las candidatas más comunes para la adopción de iPaaS, donde los conectores predefinidos y la transformación basada en la configuración reducen tanto el tiempo de compilación como el riesgo de mantenimiento.

¿Cómo simplifica Alumio la creación de integraciones entre sistemas ERP y de comercio electrónico?

Alumio simplifica la integración de ERP y comercio electrónico mediante plantillas de conectores predefinidas tanto para el lado ERP (SAP ECC, S/4HANA, Dynamics 365, NetSuite, Business Central, Odoo) como para el lado del comercio electrónico (Shopify, Adobe Commerce, Shopware, WooCommerce, BigCommerce). Las plantillas de conectores gestionan la autenticación y la comunicación de la API, de modo que los equipos de integración se centran en configurar el mapeo de datos entre los modelos de datos de ambos sistemas en lugar de crear las conexiones desde cero. La monitorización centralizada proporciona visibilidad de cada intercambio de datos de pedidos, inventario y productos, con capacidad de reproducción para los registros que fallen.

Integration Platform-ipaas-slider-right
¿Qué deberían incluir las empresas en un plan de proyecto de integración de ERP con comercio electrónico?

Un plan de proyecto realista incluye: una fase de mapeo de datos (que documenta cada campo que se transfiere entre el ERP y el comercio electrónico, incluidas las reglas de transformación), una decisión sobre la gobernanza de datos maestros (qué sistema es el autoritativo para productos, precios y clientes), una fase de pruebas de aceptación del usuario (UAT) con casos de prueba positivos y de error para cada flujo de datos, un período de ejecución en paralelo donde ambos sistemas procesan datos simultáneamente antes de la transición personalizada, y una configuración de monitorización que define quién recibe alertas cuando falla un flujo. Las integraciones de ERP que omiten la fase de mapeo son la fuente más común de problemas de calidad de datos posteriores a la puesta en marcha, que requieren costosas soluciones.

Integration Platform-ipaas-slider-right
¿Cómo afecta la calidad de la integración del sistema ERP al rendimiento de un negocio de comercio electrónico?

La calidad de la integración ERP afecta directamente al rendimiento del comercio electrónico en tres dimensiones: operativa (un inventario preciso evita la sobreventa, el procesamiento automatizado de pedidos reduce el tiempo de entrega y la fijación de precios en tiempo real previene errores en las cotizaciones y la facturación), financiera (la contabilización automatizada en el ERP elimina los errores de entrada manual y la sobrecarga de la conciliación de fin de mes) y estratégica (los datos fiables entre el ERP y el comercio electrónico permiten las inversiones en IA, análisis y personalización que impulsan la diferenciación competitiva). Las organizaciones que invierten en una integración ERP-comercio electrónico de alta calidad superan sistemáticamente a aquellas que gestionan esta conexión mediante exportaciones manuales o código personalizado frágil.
