Government Payment Terms: The 30-Day Rule and Managing Cash Flow

How the 30-day payment rule works for South African government contracts, why payments run late, and how to protect your cash flow.

The 30-Day Rule

National and provincial departments are required by Treasury rules issued under the Public Finance Management Act (PFMA) to pay valid invoices within 30 days of receipt. Municipalities carry an equivalent obligation under the Municipal Finance Management Act (MFMA). The clock runs from receipt of a valid invoice — which is where many delays actually start.

Why Payments Still Run Late

The 30-day rule is real, but so are late payments. Common causes:

  • Invalid or disputed invoices — wrong purchase order number, missing timesheets or delivery notes, amounts that do not match the order
  • No purchase order. Work done without an official order often cannot be paid at all
  • Missing milestone sign-off — payment against deliverables requires the project manager's written acceptance first
  • Lapsed CSD or tax compliance status at payment time, which can block payment runs
  • Genuine administrative backlogs, especially at struggling municipalities

Protect Yourself Before You Bid

  • Check the buyer's payment reputation. Ask other suppliers, and look at the buyer's track record before committing working capital.
  • Price the cash-flow cost in. If a client habitually pays in 60–90 days, your pricing must carry the financing cost.
  • Never start work without a signed purchase order or appointment letter, no matter the verbal urgency.

Invoice So You Get Paid

  1. Quote the purchase order number and contract reference on every invoice.
  2. Attach the proof the contract requires: delivery notes, signed timesheets, milestone acceptance certificates.
  3. Deliver the invoice to the designated address or portal and keep proof of receipt — the 30 days runs from receipt.
  4. Keep your CSD record, banking details and tax status current (tax clearance guide).
  5. Follow up in writing before due date, not after.

When Payment Is Overdue

Escalate in writing to the department's finance section, referencing the 30-day requirement; unresolved PFMA cases can be reported to National Treasury's late-payment monitoring process. Persistent non-payment is also a factor to weigh when deciding whether to bid for that buyer again — sometimes the best cash-flow decision is choosing better clients.

Research buyers before you bid: department profiles on AITenders show procurement activity and awarded contracts, so you know who you are dealing with. Start with the departments directory.
