Procurement lifecycle

Collaboration continues beyond sourcing.

From the first request for quotation to the delivery against the order, buyers and suppliers stay in one process. The ERP remains the system of record at every step.

RFQ / Sourcing

Bring suppliers into sourcing without bringing sourcing back to email.

One request, one place for requirements, quotations and clarifications. Buyers and suppliers work the same steps in the same order.

Purchase order collaboration

Purchase orders become a collaboration process.

The ERP sends the purchase order. ESS Hub presents it to the supplier, who reviews and responds. Confirmation and status flow back into the same business process.

What stays connected

What the supplier sees is what the buyer sent.

Orders, call-offs and confirmations are one object on both sides: no re-typing, no parallel spreadsheet, no status lost in a mailbox.

Order and call-off visibility

Every order line the ERP sends is visible to the supplier with part, plant, quantity and delivery date.

Supplier · Buyer

Supplier confirmation

The supplier confirms in the platform; the buyer sees who has confirmed and who has not.

Confirmation

Quantities and dates

Called and received quantities per line, with the delivery date the process is running against.

Per line

Status tracking

Open, confirmed, shipped or overdue: the same status on both sides, without asking by phone.

Both sides

Supplier communication

Messages and supplier letters with read-and-confirm tracking, next to the documents they refer to.

Messages

Documents

Specifications, instructions and agreements published to the supplier with confirmation of reading.

Documents

Forecasts & scheduling agreements

Give suppliers visibility before the order arrives.

Forecasts and scheduling agreements reach the supplier as structured demand: part, plant, quantity, date and type. The supplier plans capacity and material against the same numbers the buyer sees.

  • Demand visibility

    Forecast and JIT call-offs per part and plant, in one list.

  • Scheduling agreements

    The long-term agreement each call-off belongs to.

  • Call-offs / releases

    Firm demand with quantity and delivery date.

  • Called vs. received

    Progress per agreement, visible to both sides.

  • Status

    Open, confirmed, shipped or overdue.

  • Export

    Excel, CSV, PDF or EDI flat file for the supplier's own systems.

Supplier experience

Different supplier maturity. One procurement process.

Suppliers do not need an integration project to take part. They work in the web portal or, where appropriate, through EDI, API or file exchange. The buyer runs one process either way.

Web portalBrowser-basedQuote, confirm and review demand in the browser. No local infrastructure required.
EDIClassic EDIOrders, schedules and confirmations exchanged automatically with established standards.
APISystem-to-systemFor suppliers that integrate their own ERP or platform directly.
SFTP / FilesStructured filesScheduled, structured file exchange where that is the supplier's reality.
