The cleanest way into a big public contract is often not to beg for the whole thing. Instead, sell one hard, deliverable slice of it, get paid for that slice, and leave with a reference the market cannot ignore.
Most smaller firms fail the first tender because the prime contract is a monster. The paperwork is heavy, the balance sheet has to look sensible, the delivery footprint has to cover ground you have not covered before, and the cash has to survive the gap between work done and money landing. Subcontracting cuts through that. You still do real work on a major project, but without carrying the whole beast on your back.
Start where the primes are already looking
The lazy move is to send a one-pager after the award and hope someone notices you. By then, the decision is mostly baked.
The better move is to watch the procurement pipeline before the closing date. National Treasury’s procurement plans, published under Regulation 16A6.3, are useful here. They tell you what organs of state expect to buy, sometimes far enough ahead for you to spot the likely main bidders and work out who will need help. The e-Tender Portal at `etenders.gov.za` is the other obvious place to watch, as it publishes tenders above R500,000 and gives you the actual notice trail, not rumours from somebody’s cousin in supply chain.
If a department is likely to buy facilities maintenance, cleaning, security, ICT support, stationery, electrical materials or transport services, you should already be asking which large firms win those jobs repeatedly. That is the prime contractor shortlist. You can build it from prior awards, departmental websites, supplier days, chamber events and the usual industry gossip, then confirm it against actual tender history.
Do not pitch yourself as a whole-company solution. Show up with one component they can plug into a bigger bid.
Sell the slice, not the sermon
A prime contractor does not want your company profile. They want something they can price into a submission.
If the tender is for a national facilities contract, the useful pitch is not “we do maintenance”. It is “we can handle the Eastern Cape portion”, or “we can cover the provincial call-outs in KwaZulu-Natal”, or “we can manage the reporting and on-site maintenance package for one province.” The more specific you are, the less you look like a random invoice waiting to happen.
This is especially true on big public work, where the prime is trying to cover geography, compliance, capacity and delivery risk at once. A smaller operator can sometimes do the actual work better than the prime’s own team, but still lose if they cannot package the offer in a way that fits the bid.
Price the work like a grown-up
The fastest way to lose money on subcontracting is to price it like a normal job. It is not a normal job. There is extra admin, extra reporting, more movement, more waiting, and usually more nonsense.
Work the number from the bottom up:
- labour, including wages and statutory costs
- materials and consumables
- tools and equipment
- travel, fuel, vehicle wear and, if the work sprawls across provinces, accommodation
- reporting and admin time
- insurance and compliance costs
- your overhead
- your profit
Then leave room for the prime contractor’s margin. They are not going to do all the coordination for charity. In practice, a prime will often load around 5% to 15% on top of the subcontracted portion for management, risk and administration. If you are offering a provincial maintenance component inside a larger national contract, your price has to still leave enough air in the room for them to make money too.
A simple example: say your piece is 12% of the contract value, and you are responsible for maintenance in one province. If your labour, travel, materials, reporting, insurance and overheads eat most of that 12%, you have built yourself a busy, profitable-looking loss.
Get the contract before the spade goes in the ground
This is where too many small firms get sentimental and stupid.
Do not start work on a promise, a warm email or a purchase order that has not been turned into an actual subcontract. If the paper is not signed, your leverage is thin and your legal position is uglier than the story you will tell your bank manager later.
A proper subcontract should spell out payment timing, scope, changes, liability, confidentiality, termination and who owns the client relationship. If you are supposed to get paid 30 days after a valid invoice, say that. If payment is milestone-based, say that too. If there is retention, usually 5% to 10%, pin down when it gets released and under what conditions.
Late payment should also have consequences. The Prescribed Rate of Interest Act sits in the background here, and contractual debt interest has been 11.75% per annum since July 2023. If a prime wants the comfort of your delivery, they can live with the cost of paying late.
Scope creep is just unpaid work with better branding
Big contracts shift. Someone in the chain changes a spec, a site moves, a report format becomes “urgent”, or a client adds another branch because it is easier than fixing the first brief. If your subcontract does not force a written change order before the work starts, you will end up eating the variation.
The change process needs to be boring and written. New instruction, impact on price, impact on timing, approval from both sides. No approval, no work. That rule saves more small businesses than any pep talk ever will.
The same goes for customer ownership. In most cases, the prime keeps the relationship with the department or municipality. You are not there to build a side hustle on the client list behind their back. Your subcontract should deal with direct contact, future solicitation, confidentiality and any intellectual property created during the job. If the work produces something new, the rights need to be clear before anybody starts patting themselves on the back.
Current rules are not the same as the draft rules
Under the current PPPFA framework, subcontracting is generally encouraged where an organ of state wants it, but it is not a blanket legal requirement on every contract. The current system is still built around preference points, and Regulation 9 in the 2017 framework deals with limits on subcontracting to enterprises with lower B-BBEE status in certain cases. In plain English, the current regime can shape subcontracting, but it does not yet force it across the board.
The draft Public Procurement Bill is a different animal. The 2026 direction of travel is toward more explicit subcontracting obligations on certain contracts, including specified portions that may need to go to local SMMEs where appropriate. This is a real shift. If it lands in the form expected, primes will need small firms in a more structured way, not as an afterthought once the bid is already in.
This creates an opening for operators who are ready early. This means firms that already know which prime will need help, what province they can cover, and how much the work actually costs, not just the ones that only wake up when the tender advert appears.
The trap is thinking scale and control are the same thing
Direct tendering gets the glory because people like the idea of winning the whole thing. Winning the whole thing is nice until payroll lands, the paperwork multiplies, the client changes the brief and the cash takes its own sweet time.
Subcontracting is less glamorous and often smarter. It lets a smaller business build delivery history on a major public project without taking on the full balance-sheet stress of being the prime. It also gives you proof. One decent subcontract delivered cleanly is worth more than ten glossy capability statements.
Before signing anything material, get proper legal help. The money gets real fast once your name is on the paper.
