Reading an invitation to tender: the returnables that decide compliance

Most tender documents follow a recognisable order: an invitation and notice page with the bid number and closing details, conditions of tender, the specification or scope of work, the pricing schedule, the returnable schedules, and the draft contract.

Only some of that comes back to the buyer. The conditions and specification are for you to read; the returnables are for you to complete, sign and submit. Confusing the two, and submitting the whole document unmarked, is a common first-time error.

The SBD forms are National Treasury's standardised returnables, and the same numbered forms appear across most organs of state. You will typically meet the invitation to bid form, a pricing schedule, a bidder's disclosure covering conflicts of interest, a preference points claim form, a declaration of past supply chain practices, and a certificate of independent bid determination.

Two cautions. First, the numbering and content of these forms are being revised under the Public Procurement Act 28 of 2024, so the set you used two years ago may not match the current pack. Second, and more important in practice, always complete the copies bound into the tender document rather than blank versions downloaded elsewhere. The bound copies usually carry the bid number, and buyers check against the version they issued.

The declaration forms look like formalities and are not. The conflict of interest disclosure asks whether any director is employed by the state or related to someone who is, and an undisclosed relationship discovered later can void an award and trigger consequences beyond the contract.

The certificate of independent bid determination is a statement that you did not coordinate your price with another bidder. It exists because bid rigging is prosecutable under competition law, and signing it while having discussed pricing with a competitor is a serious matter, not a paperwork risk.

Where a tender uses functionality scoring, the evidence is carried by the technical returnables rather than the SBD forms. These typically ask for company experience on similar contracts, CVs and qualifications for named key personnel, a method statement describing how you will do the work, and a plant, equipment or staffing schedule.

Score these against the published matrix before you write them. If the matrix awards points for three comparable contracts in the last five years, list three and attach the reference letters, rather than describing your general experience in prose. Evaluators score what the matrix asks for, and cannot award points for evidence you did not supply in the form requested.

Administrative elimination happens before anyone assesses your capability. These are the recurring causes, and every one of them is avoidable with a checklist and an hour.

The reliable method is to make an index from the returnable schedule list before writing anything, with one line per required item and a tick box. Complete the index, then assemble the document to match it, then check it once more against the conditions of tender.

This sounds bureaucratic and takes about an hour. It is also the difference between a bid that gets evaluated and a bid that does not, which makes it the highest return hour in the whole exercise.
