SOBERAN / PROCUREMENT OPSSYNCED
ERP SOURCE+SUPPLIER SIGNALS+POLICY
OPEN PO→CONFIRMATION→PROMISED DATE→RECEIPT→AUDIT TRAIL
01 / Control after issuance
Approval is not the end of purchase-order control.
An approved PO can still change in price, quantity, date, shipment plan, receipt, or invoice status. Control means preserving who changed what, why it changed, what policy applied, and which operational promise now governs the order.
02 / Visible lifecycle
Six control points across the PO cycle
Good governance follows the order after creation and keeps the commercial, operational, and receiving records aligned.
- 01→
Authorization
Budget, supplier, terms, and approval authority are verified
- 02→
Issuance
The exact version sent to the supplier is retained
- 03→
Commitment
Supplier-confirmed price, quantity, and date are recorded
- 04→
Amendment
Material changes follow the correct approval path
- 05→
Receipt
Partial and complete receipts reduce the open balance correctly

Closure
Outstanding exceptions are resolved before the PO closes

Policy-based approvals
Route price, quantity, date, supplier, and other material changes according to impact and authority.
Closure discipline
Prevent silent closure when quantities, receipts, invoices, or unresolved exceptions remain open.

One procurement problem. Three levels of control.
06 / FAQ
Before replacing another spreadsheet.
What is purchase order control?+
Purchase order control governs authorization, issuance, supplier confirmation, amendments, receipts, exceptions, and closure so the current PO state is accurate and every material change is traceable.
What should a purchase order control system track?+
It should track the PO version, supplier commitment, promised dates, quantities, partial receipts, amendments, approval status, exception owner, source evidence, ERP writeback, and audit timestamps.
How is purchase order control different from procurement approval?+
Approval authorizes the purchase before issuance. Control continues afterward by governing supplier responses, changes, receipts, exceptions, and closure.
Can SOBERAN add control without replacing the ERP?+
Yes. The ERP remains the system of record while SOBERAN adds signal capture, exception workflow, approvals, ownership, and controlled writeback.
