SAP Consulting and Integration: Connect SAP to Your Business Processes and Applications

I provide process consulting to companies running SAP Business One and S/4HANA, and build two-way integrations between SAP and e-commerce, mobile field, production and reporting applications.

Quick answerSAP consulting is the expert service of tailoring an SAP ERP system to a company's business processes, integrating it with other software and building reporting on top of it. Hakan Sevimoğlu is an SAP consultant and software developer who handles process analysis, OData/Service Layer and RFC-based integration, and SAP-connected mobile and web applications in SAP Business One and S/4HANA environments.

What does my SAP consulting cover?

SAP's standard screens often can't keep up with the pace of sales, warehouse and production teams in the field. First, the current processes and SAP configuration are analyzed; then it is decided which work stays inside SAP and which moves to a lightweight mobile/web app connected to it.

Next come integrations such as e-commerce orders flowing into SAP automatically, warehouse counts transferred from handheld terminals into SAP, and a B2B dealer portal reading account and pricing data from SAP. For details, see my article on SAP integration and SME ERP solutions.

Which SAP environments?

I work with SAP Business One (Service Layer / DI API), common among SMEs, and SAP S/4HANA (OData, RFC/BAPI, IDoc) on the enterprise side. In mixed setups with non-SAP ERPs such as Netsis and Logo, data flow is also managed from a single hub.

What I offer

  • Process analysis

    Mapping sales, purchasing, warehouse and production flows to SAP.

  • Integration

    Two-way data flow via OData, Service Layer, RFC/BAPI and IDoc.

  • Mobile field apps

    Counts, shipments and orders into SAP from handheld terminals and tablets.

  • E-commerce & B2B

    Order, stock and customer account sync with SAP.

  • Reporting & BI

Frequently asked questions

What does SAP consulting include?
