Riegg & Partner Intercorp GmbH
Intercorp: 26 years of shop expertise
Riegg & Partner intercorp. GmbH is an AI and web agency based in Northern Bavaria, with offices in Nuremberg and near Bayreuth.
We develop modern e-commerce solutions with Shopware 6 that go far beyond a “standard shop + a few apps.” Our focus is on true process digitalization: through custom plugins, stable API interfaces, and middleware that reliably connects your system landscape.
Many projects don’t fail at the shop frontend, but at the integration behind it. Data is scattered, exports/imports are error-prone, and historically grown processes slow down growth. CSV/XML can solve isolated tasks — APIs create robust automation. That’s exactly where we come in: we build interfaces that are up-to-date, versioned, secure, and maintainable in operation, so Shopware, ERP, PIM, CRM, logistics, and payment systems work together seamlessly.
Our focus areas in Shopware projects:
Plugin & extension development for Shopware 6
Custom features for checkout, catalog, admin workflows, customer/permissions logic, shipping/payment, and import/export — update-safe, clearly documented, and built for long-term operation.
API & interface development (Shopware + third-party systems)
Design and implementation of REST APIs including API documentation, versioning, clear error handling, authentication/roles/permissions, rate limits, logging/monitoring, as well as webhooks and event-driven flows.
ERP/PIM/CRM integrations & middleware
Robust integrations for master data, pricing, inventory, orders, customer and shipping processes — including data consolidation across multiple sources.
Migration & data transfer
Structured migration of data from legacy systems and platforms into Shopware (including cleansing, mapping, and quality assurance).
Custom process tools & AI assistance systems
Symfony/PHP and JavaScript-based web applications that reduce workload for teams — up to dialog and assistance systems within your platform, ERP, or CRM processes.
In short: intercorp. turns Shopware into a central control hub — with plugins, APIs, and integrations that work reliably in everyday operations.
If you like, we can start with a quick check: Which systems need to be connected, where are the bottlenecks, and which integration path will deliver measurable value the fastest?
