Procurement and eTIMS lessons

From PO to GRN and Debit Notes: managing your supplier chain under eTIMS compliance.

Procurement Lessons: From Purchase Order to eTIMS Compliance

Efficient procurement is the foundation of healthy profit margins. For businesses in Kenya, procurement has also become a critical compliance checkpoint due to the Kenya Revenue Authority (KRA) eTIMS requirements.

1. The Standard Procurement Workflow

A healthy procurement cycle follows these structured steps:

  1. Purchase Requisition: Internal team requests materials.
  2. Purchase Order (PO): Formal offer sent to the supplier specifying items, quantities, and agreed prices.
  3. Goods Received Note (GRN): Warehouse checks arriving goods against the PO and records the quantity received.
  4. Supplier Invoice Matching: The finance team matches the GRN against the supplier's invoice.
  5. Payment Settlement: Approving the match triggers accounts payable to release the payment.

2. Managing Returns with Debit Notes

If the received goods are damaged, incorrect, or overpriced, you must issue a Debit Note to the supplier. This note formally requests a reduction in the amount you owe them (accounts payable) and adjusts the inventory value in your books.

3. eTIMS Integration in Procurement

In Kenya, you cannot claim tax deductions for business purchases unless the supplier issues an eTIMS-compliant invoice. Your ERP system must:

  • Capture the supplier's eTIMS invoice details.
  • Validate the invoice against the received GRN.
  • Keep a digital audit trail showing the link between the PO, GRN, Debit Note, and the final tax filing.
