Same process. Any ERP.
Built for SAP landscapes. Open to every ERP.Standards and technologies in daily use at EDI & SAP Solutions since 2013.
From fragmentation to one process
Different supplier channels should not create different enterprise processes. ESS Hub puts one collaboration layer between suppliers and the enterprise landscape.
Platform
ESS Hub covers the document flows between an enterprise and its suppliers, from demand to invoice, in one consistent workspace for procurement, logistics and finance.
Publish orders to suppliers, track confirmations and changes, and keep every version in one place, for the buyer and the supplier.
Order · confirmation · change historyShare demand forecasts so suppliers can plan capacity and material against your actual requirements, not against assumptions.
Demand visibility for suppliersCommunicate delivery schedules and call-offs against long-term agreements, with quantities and dates suppliers can act on.
Schedules · call-offs · releasesSuppliers announce shipments before goods arrive: advance shipping notices with packaging data and labels, prepared in a guided flow.
Advance shipping notice · packaging · labelsSuppliers submit invoices against orders and deliveries. Finance receives structured invoice data that can flow into ERP and AP processes.
Structured invoice data · ERP-readyRun requests for quotation and collect supplier quotes in one place, with a clear record of who was invited and what was offered.
Sourcing events · quotationsBring new suppliers on board with the right roles and permissions, and the connection method that fits their capabilities.
Roles · permissions · connection setupNotices and messages tied to the process they belong to, with read receipts, instead of untracked e-mail threads.
Share and track business documents with suppliers in the context of the order, shipment or agreement they belong to.
Supplier connectivity
Not every supplier connects the same way. ESS Hub lets each supplier work through the channel that fits its capabilities, while the enterprise receives one consistent process.
Orders, schedules, ASN and invoices handled in the browser, in the supplier's language, with no integration project on their side.
Smaller and occasional suppliersSuppliers with established EDI exchange standard messages directly, such as EDIFACT, VDA or ANSI X12 formats, through the ESS Hub integration layer.
Tier-1 and high-volume suppliersSuppliers and partner systems that integrate programmatically exchange the same business documents through APIs.
Digitally mature suppliers and platformsStructured files exchanged on a schedule over SFTP, for suppliers whose systems export and import files rather than messages.
Suppliers with file-based ERP exportsThe enterprise side does not change. The same purchase order, the same ASN, the same invoice arrive in the same process and the same ERP interface, regardless of how the supplier connected.
Architecture
The portal is one interaction layer. The product is the layer underneath: business document workflows connected to your ERP through standard enterprise interfaces.
The product
ESS Hub is a real application with real supplier workflows. This section is reserved for screenshots of the platform itself, not for conceptual illustrations.



ERP integration
Built for complex SAP environments. Ready for any ERP that speaks standard enterprise interfaces.
SAP heritage
EDI & SAP Solutions has designed and operated SAP integrations for more than a decade: IDoc interfaces, EDI subsystems and middleware such as Seeburger BIS, in ECC and S/4HANA environments. ESS Hub is built with that experience, so purchase orders, schedules, ASNs and invoices arrive in the structures your SAP processes already expect.
Open architecture
ESS Hub does not depend on a specific ERP. It can integrate with other ERP and enterprise backends through the same integration layer, using standard interfaces rather than proprietary connectors.
Why ESS
EDI & SAP Solutions SRL was founded in 2013 in Brașov, Romania. For more than a decade the company has designed, built and supported integration landscapes for manufacturing and automotive companies: SAP, EDI and B2B integration, Seeburger BIS, EDIFACT, VDA and ANSI X12 messaging, IDoc interfaces, API integration and SFTP/MFT file exchange, together with enterprise support and development.
ESS Hub is the productization of that work. It is the supplier-facing layer designed for the integration landscapes ESS has been connecting for years, built by the same team that runs the EDI and SAP interfaces behind them.
Security & architecture
Supplier collaboration touches orders, prices and invoices. ESS Hub is designed around the controls that enterprise IT and procurement expect from a platform that sits between suppliers and the ERP.
Business roles for supplier and enterprise users; a data-driven permission matrix defines what each role can see and do.
