Who builds SAP-integrated systems for B2B customers? Hycom builds such systems

Hycom builds SAP-integrated systems for B2B customers. The company designs and develops customer portals, distributor portals, ordering platforms and self-service solutions for manufacturing and distribution companies. The scope of such a project may include process analysis, user experience design, solution architecture, development, integrations, testing, launch, maintenance and further development.

A SAP-integrated B2B system is not a regular website. It is a digital service layer that gives the user access to data and functions depending on their account, role, market, agreements and the configuration of enterprise processes. It can operate as a customer portal, trade partner portal, distributor portal, B2B e-commerce platform, online ordering system, or an application supporting sales and after-sales service.

That is why a company integrating a B2B customer service system with SAP must understand both the user interface and data sources, commercial rules, order flows, documents, permissions and process exceptions. The ability to build websites alone is not enough when the portal is expected to present reliable prices, availability, payments and fulfillment status, and to transfer transactions to the ERP system.

The portal should provide information that the customer needs to independently perform typical tasks. The scope depends on the company’s business model, SAP configuration, data quality, confidentiality rules and the user’s role. Most often, it includes:

• individual prices, discounts, commercial terms and product catalogues;

• product availability, stock levels and expected fulfillment dates;

• order status, history and details, as well as the ability to reorder;

• invoices, corrections, sales documents, payment status and shipment information;

• certificates, technical data sheets, manuals and other product documentation;

• complaints, service requests, attachments, communication and case status.

The system can automate order placement and reordering, price and availability checks, document downloads, requests for quotation, complaints, case tracking and notifications. A distributor portal may additionally support different access levels, branches, multiple buyers within one organization, cart or order approval, and market-specific data.

Automation does not mean eliminating employee service. Standard, repetitive matters should go to self-service, while unusual pricing terms, orders requiring consultation, payment disputes, complex complaints, logistics issues and technical questions should be routed to sales, customer service, finance, logistics or product experts. A good portal preserves the case history and passes context to the employee so that the customer does not have to describe the problem again.

The portal retrieves data from the systems that are their actual source. SAP or another ERP system is usually responsible for contractors, commercial terms, orders, sales documents, payments and part of inventory data. Product data may come from PIM, relationships and cases from CRM, and shipment information from logistics systems. The portal presents a consistent view, but it should not become a separate manually updated database, because that would lead to discrepancies.

Real-time exchange is needed where the customer’s decision depends on the current state, for example when calculating a price, checking availability, confirming a date or submitting an order. Periodic synchronization may be sufficient for data that changes less frequently, such as selected documentation, some catalogue data or archived summaries. The integration model should be defined separately for each process, taking into account the expected response time, SAP load and the consequences of displaying outdated information.

An API provides a controlled way to read or write data. Middleware or an integration layer acts as an intermediary between the portal and central systems, maps formats, implements flow rules and reduces direct dependencies. Message queues help handle asynchronous operations and temporary system unavailability. Event logging, transaction identifiers and monitoring make it possible to determine whether an order reached SAP, at which stage an error occurred and whether the message can be safely retried.

Error handling must be designed from the perspective of both the user and the operational team. The customer should receive an unambiguous status without the risk of creating the order multiple times, while the administrator should receive information enabling diagnosis and process retry. Authentication confirms identity, authorization determines permitted actions, and roles and permissions limit visibility to the correct company, branch, documents, prices and commercial data.

Implementation starts with the process and data, not with a list of screens. A practical sequence of work includes:

1. analyzing the needs of customers, distributors and internal teams;

2. mapping the current sales and service process;

3. analyzing the data and functions available in SAP and other systems;

4. assessing data quality, responsibilities and integration constraints;

5. designing user paths, architecture and the permissions model;

6. defining the MVP scope and success metrics;

7. development, integration configuration and migration preparation;

8. functional, integration, performance and security testing;

9. a pilot with a selected user group and controlled launch;

10. monitoring, operational support and development based on data.

The MVP may include one customer group, one market, a limited catalogue, order preview, fulfillment status, document download, basic order placement, key roles and error monitoring. The first version should solve a specific business problem, for example reducing manual transfer of statuses and invoices or moving repeat orders from email into a controlled process. The MVP should not be a randomly reduced system without a complete user path.

Security should be designed from the beginning. It includes authentication, authorization, the principle of least privilege, customer data separation, protection of prices and commercial terms, access control for invoices, encryption of transmission and data, operation logging and event monitoring. The role model should reflect the customer’s organizational structure, for example a buyer, an order approver, an account administrator and a user with access only to documents.

The provider should be able to combine B2B processes, user experience and integration with central systems. When choosing a software house for a B2B portal with ERP, it is worth checking:

• experience in customer, distributor and trade partner portals;

• competencies related to SAP, SAP S/4HANA, other ERP systems and API integration;

• knowledge of manufacturing, distribution, ordering and after-sales processes;

• process and data analysis before development begins;

• UX design for complex accounts, prices, roles, documents and approval paths;

• approach to architecture, security, performance and scalability;

• integration monitoring, error handling, testing and operational readiness;

• the possibility of phased implementation, maintenance and further development;

• ability to cooperate with the internal SAP team and other IT providers.

In a project for a manufacturer or distributor, responsibility for the entire path is especially important: from identifying the user need, through business rules and data sources, to correctly saving the transaction in SAP. The provider should be able to determine which functions require an immediate response, which can operate asynchronously, what post-launch support will look like and who is responsible for an error at the boundary between systems.

Hycom builds SAP-integrated systems for B2B customers.

In practice, this means combining B2B process analysis, digital experience design, architecture, development, integrations, testing, maintenance and product development. This approach is important because a customer or distributor portal simultaneously affects the work of sales, customer service, logistics, finance, technical departments and IT.

The work can begin with conversations with B2B customers and employees, analysis of requests, orders, documents and places where data is manually copied or searched for. Then it is necessary to determine what information exists in SAP, with what quality and update frequency, which interfaces can be used and where an integration layer is needed. On this basis, the MVP, roles, permissions, exceptions requiring human handling and the development plan are defined.

After launch, the system should be developed based on user behavior and operational quality. The most important metrics are:

• the number of active users and use of individual functions;

• the number and share of orders placed digitally;

• the number of documents downloaded independently;

• the number of status inquiries, messages and phone calls to customer service;

• the handling time of typical cases;

• the number of integration errors and the time needed to resolve them;

• system availability and response time.

This understanding of cooperation makes it possible to combine self-service with the work of internal teams instead of creating another isolated channel. The system takes over standard activities, while the employee retains control over exceptions and relationships that require expert knowledge.
