Government and large corporates in South Africa buy a great deal from small businesses, and they are obliged to buy it through a process. That process is the tender, and it is the reason a two-person firm can end up supplying a municipality. It is also slow, document-heavy, and unforgiving of paperwork errors — most bids that fail, fail before anyone reads the price.

This is what you need in place before you can bid at all, and what the process actually looks like from the inside.

Before anything else: the documents

You cannot assemble these in the week a tender closes. Every one of them takes time to obtain, and several depend on each other. Get them before you go looking for work.

  • A registered company. A CIPC registration number, and a company that is in good standing — meaning your annual returns are filed and up to date. A lapsed company is invisible to procurement.
  • Tax compliance. SARS issues a Tax Compliance Status with a PIN that lets a buyer verify you in real time. It replaced the old paper tax clearance certificate. If you owe SARS and have no arrangement, this is where the process stops.
  • A B-BBEE affidavit or certificate. Smaller businesses can usually use a sworn affidavit rather than paying for verification. Which one applies depends on your turnover, and the threshold is worth confirming rather than assuming.
  • Banking details in the company's name. Not a personal account. Buyers pay registered entities.
  • Proof of address and directors' identity documents. Routine, and routinely the thing somebody cannot find at 4pm on the closing day.

If you are in construction or anything the state classifies as construction works, you will also need a CIDB registration and grading. The grade caps the value of the work you may tender for, which means the grading is not administrative — it decides which tenders you are allowed to see through to the end.

Register on the CSD

The Central Supplier Database is National Treasury's single register of suppliers to the state. Organs of state are required to source from it, so if you are not on it you are not in the running, whatever else you have.

Registration is free and done yourself. It pulls your details from CIPC and SARS rather than taking your word for them, which is why the documents above have to be in order first — the registration will simply reflect back whatever the state already believes about you. A supplier number comes out the other end, and you will be asked for it constantly.

Two things people get wrong. The first is treating it as once-and-done: your details, particularly your tax status, are re-verified, and a registration that has gone stale is as good as none. The second is registering under commodity codes that describe what you would like to do rather than what you can prove you do. Buyers filter on those codes.

Finding the work

Government tenders are published on the national eTenders portal, and provinces, municipalities and state-owned entities also advertise on their own sites and in the Government Tender Bulletin. Large private buyers run their own supplier portals, usually attached to an enterprise and supplier development programme.

The useful discipline here is narrowness. It is tempting to set alerts wide and read everything. Bidding is expensive in time, and a bid you were never going to win costs the same to prepare as one you were. Pick the buyers who are geographically close to you and who buy what you already sell, and learn their patterns — most of them buy the same things on a cycle.

Reading the tender document

Every tender document splits into two halves, and confusing them is the most common reason a good supplier loses.

Mandatory requirements are pass or fail. A missing signature, an unsigned SBD form, a certificate that expired last month, a missing initial on an amended page — any of these gets the bid set aside without the evaluation ever reaching your offer. This is not officiousness; the buyer is legally exposed if they overlook it. Treat the document's own checklist as the checklist.

Scored criteria are where the competition actually happens: price, and then preference points, and often functionality or technical capability assessed against stated criteria. The point-scoring framework for preference has changed more than once in recent years and has been through the courts, so read the formula printed in the tender you are holding rather than the one you remember from the last bid.

If there is a compulsory briefing session, attend it. It is frequently a mandatory requirement in its own right, and it is the one opportunity to ask the buyer what they actually want.

Why bids get thrown out

In rough order of how often it happens: incomplete or unsigned standard bidding documents; an expired or missing compliance document; submitted late, or to the wrong physical address; pricing that does not follow the required format, or arithmetic that does not add up; a CIDB grade below the value of the work; and quoting for something adjacent to what was asked for rather than the thing that was asked for.

Almost none of that is about capability. It is about assembly, and assembly is a skill you build by doing it.

What it really costs

Budget the time honestly. A first bid to a new buyer can take a week of somebody's attention between gathering documents, attending a briefing, pricing properly and physically getting the submission in. Subsequent bids to the same buyer are much faster, because most of the pack is reusable and you have learned their format.

Then budget for the wait. Adjudication takes months, and payment terms after award are their own subject. A tender win is not cash; it is a contract that will require working capital before it produces any. Businesses have been sunk by winning something they could not fund.

When not to bid

Do not bid to make up numbers. Do not bid on work you would have to sub-contract entirely, unless the tender says you may and you have the sub-contractor confirmed. Do not bid at a price you cannot deliver at in the hope of renegotiating — you will not be renegotiating.

And do not bid on your first one alone if you can help it. Ask another supplier who has done it what tripped them up. The paperwork is public and the process is deliberately transparent; the knowledge of how to move through it is not, and it is mostly passed on by people who have already lost a bid to something avoidable.

This is a general description of how public procurement works in South Africa, not legal or financial advice, and thresholds and scoring frameworks change. Confirm the current requirements against the tender document itself and against the relevant authority before you rely on any of it.
