Know which tenders are worth bidding for.

Why most South African SMEs bid far too often

A tender submission costs a small business somewhere between forty and a hundred and twenty hours once you count the site meeting, the pricing schedule, chasing certified copies, and the two evenings spent formatting a technical proposal.

Price that at even R350 an hour of owner and admin time and a single bid costs you R14,000 to R42,000 before you print a page. Most SMEs never account for it, because it does not appear on a bank statement. It appears as the month you had no time to invoice.

The discipline is not in writing better bids. It is in writing fewer of them, and putting the recovered time into the ones you can actually win. That is the entire purpose of a bid/no-bid decision.

Why “unsure” is the most dangerous answer

In the calculator above, an unsure answer scores half marks — not because half is fair, but because unsure is not neutral. Every unsure is an unfinished task with a deadline attached. If four criteria are unsure a week before closing, you do not have a 70% opportunity. You have a 70% opportunity and four unpaid days of work standing between you and finding out.

The twelve criteria, explained for South African tenders

Why each one carries the weight it does.

What gets South African bids thrown out before pricing is opened

• ✓An expired B-BBEE certificate or affidavit. Valid for twelve months. The single most common disqualifier, because bidders reuse the copy from their last submission without checking the date.
• ✓No CSD registration, or a CSD profile with details that do not match. The buyer pulls your profile from the database. If the CIPC name, banking letter and ID copies disagree, that is a finding against you.
• ✓A missing or lapsed SARS Tax Compliance Status PIN. The old tax clearance certificate was withdrawn in 2016. Buyers verify your status live.
• ✓Uncertified or stale ID copies. Certification is generally required within the last three months, for every listed director.
• ✓Unsigned SBD forms or declarations. An unsigned declaration is treated as an incomplete return.
• ✓A pricing schedule altered, left incomplete, or priced in the wrong format. Use their schedule, in their format, filled in completely.
• ✓Missing the compulsory briefing or site inspection. No attendance certificate, no bid. This one cannot be fixed afterwards.
• ✓No COIDA Letter of Good Standing where staff will be on the buyer's premises.
• ✓Late submission. A tender closing at 11:00 means the box is sealed at 11:00.
• ✓Documents attached in the wrong envelope or the wrong file on the electronic portal.

Nine of these ten are administrative. None of them are about whether you could have done the work well. That is what makes them worth a checklist.

Compliance documents and how long they last

The documents most often requested. Always confirm against the tender document itself.

An EME with turnover below R10 million can generally use a sworn affidavit rather than paying for a verification certificate. Note also that the Public Procurement Act 28 of 2024 has been signed and draft regulations were published in April 2026 — the day-to-day picture has not shifted yet, but check the tender document rather than assuming last year’s rules.

A worked example

A Gauteng cleaning company is looking at a twelve-month contract for a municipal building, advertised around R2,000,000.

• Labour for eight cleaners and a supervisor: R1,180,000
• Consumables and chemicals: R210,000
• Equipment and machine servicing: R95,000
• Transport and supervision visits: R88,000
• Administration, insurance and finance costs: R160,000

That is R1,733,000 before contingency. Add 5% and the total cost is R1,819,650, leaving a gross profit of R180,350 — a margin of 9.0%. Against a written minimum of 15%, this is a no-bid on price alone; the company would need roughly R2,140,000 to reach a 15% margin.

The cash-flow line matters just as much. At roughly R151,600 of cost per month and thirty-day payment terms, the company must fund about R151,600 of wages and consumables before the first invoice is paid — and municipal payment is frequently slower than thirty days. On a 9% margin, one late payment cycle consumes most of the year’s profit.

The useful outcome here is not “we lost”. It is a documented reason to decline, and a number — R2,140,000 — to test against the market before the next similar tender appears.
