Acceptance, sign-off and payment in South African project contracts.

A supplier may believe the work is finished while the client believes it is still under review. If the contract does not connect evidence, acceptance and payment, completion can become a matter of opinion.

The objective is not to make every deliverable mechanically measurable. It is to use objective evidence where possible and a defined, fair decision process where judgment is unavoidable.

Why “to the client's satisfaction” is rarely enough.

Satisfaction describes an outcome. It does not necessarily provide a usable acceptance process.

In a tailored Agreement Build, Operative.law considers the deliverable, evidence, decision-maker, review process and applicable governing documents. The appropriate acceptance mechanism depends on the particular matter.

This guide is a design lens, not a universal clause.

The acceptance chain.

  1. 01

    Deliverable

    State what must be produced, including boundaries, exclusions and any client inputs on which delivery depends.

  2. 02

    Evidence

    Identify the record or output that shows delivery: a test result, delivery record, system output, report, file, demonstration or other appropriate proof.

  3. 03

    Reviewer

    Name the person, role or authorised representative who can decide. Delivery should not wait on an undefined group of stakeholders.

  4. 04

    Review window

    Give the reviewer a defined period and a route for raising specific reasons why the work does not meet the agreed standard.

  5. 05

    Consequence

    Connect valid acceptance or the agreed treatment of silence to the next step: correction, invoicing, payment, handover or project progression.

Objective where possible. Procedurally fair where judgment is unavoidable.

Some work can be tested against clear outputs: system behaviour, quantities, delivery records, agreed formats or defined milestones. Other work involves professional or aesthetic judgment that cannot be reduced to a binary test.

For judgment-heavy work, a tailored Agreement Build can consider the decision-maker, review process, reasons for rejection, revision structure and escalation path. Whether silence should have a contractual consequence depends on the particular matter.

The contract should not pretend that judgment has disappeared.

It should define who exercises that judgment, the agreed basis and the process by which the decision becomes commercially usable.

Payment and change must follow the same map.

If payment depends on acceptance, the invoice trigger should use the same deliverable, evidence and review process. A contract can appear to have a clear payment date while leaving the preceding acceptance event indefinitely open.

Change control matters because a revised deliverable may also require revised evidence, acceptance criteria, timing and price. The additional work should not reach delivery while the contract still records the original bargain.
