The Twenty Businesses at a Glance — and the Government Gate
Grouped by the gate they pass through. Group A sells to national departments, the metro and state agencies: entry is fast, competition is heavy, and the binding constraint is working capital rather than skill.
Gross margin is revenue less direct cost of sales, before overheads, salaries, finance costs and tax. Entries 9 and 11 carry heavy fixed and finance costs that consume much of the gross; entries 10 and 16 are almost pure labour.

Group AThe government gate
These sell to national departments, the metro and state agencies. The gate is Central Supplier Database registration plus, for some, a professional or trade credential. Entry is fast, competition is heavy, and the binding constraint is working capital rather than skill. Entry 4 is the exception and the standout.
Government supply and ICT procurement
Supply of consumables, ICT hardware, furniture and general goods to national departments, the metro and state agencies on quotation and contract.
- Why Pretoria
- The head offices of every national department procure here, generating continuous request-for-quotation volume across hundreds of buying units
- Capital
- R120,000 – R400,000, dominated by stock float and delivery capacity
- Revenue model
- Per-quote supply, with standing contracts and transversal arrangements as the durable version
- Gross margin
- 15–22%, thin because the field is enormous and price-scored
- Key risk
- Payment cycles. This is the archetypal profitable business that dies of cash. Never fund an order from your own reserves without a facility behind it
- Compliance
- CIPC, SARS tax compliance status, Central Supplier Database with your MAAA number, B-BBEE affidavit, and departmental vendor registration
- First contract
- Register on the CSD, then work the buying units in person. Aim to become the reliable supplier of one narrow category rather than a generalist quoting everything
Public estate facilities management
Maintenance, cleaning, HVAC servicing and minor works across the very large stock of state-occupied buildings.
- Why Pretoria
- The national government estate is concentrated here — departmental head offices, courts, hospitals, police stations and agency buildings, most of them ageing and all requiring continuous maintenance under term contracts
- Capital
- R500,000 – R1.2m: tools, vehicles, materials float and qualified staff
- Revenue model
- Term maintenance contracts providing an annuity, with project work as the upside
- Gross margin
- 22–30% depending on the labour-to-materials ratio
- Key risk
- Underquoting a multi-year fixed-price contract, and CIDB grading capping the value of work you may tender for
- Compliance
- CIDB registration and grading, registered electricians and plumbers for those trades, occupational health and safety compliance, Compensation Fund letter of good standing
- First contract
- Start at a low CIDB grade on private and body corporate work, deliver cleanly, and grade up. Grading is earned through completed contract value and cannot be shortcut
Conference, events and protocol services
Venue coordination, technical production, delegate management and protocol support for government conferences, summits, diplomatic functions and university events.
- Why Pretoria
- The capital hosts a continuous calendar of state functions, departmental conferences, bilateral meetings, academic congresses and diplomatic events. This demand is structural and largely recession-insensitive because it is budgeted
- Capital
- R300,000 – R800,000: audiovisual equipment, staging, staff and working capital
- Revenue model
- Per-event fee plus equipment hire and delegate services; retainer arrangements with departments and institutions are the goal
- Gross margin
- 26–34%, better where you own equipment rather than subcontracting it
- Key risk
- Concentration and seasonality. Events cluster in certain months, and a single departmental relationship can end with a change of administration
- Compliance
- CSD registration, public liability insurance, event safety compliance, and municipal permissions for larger gatherings
- First contract
- Subcontract technical production to an established agency first. You learn the protocol expectations, which are exacting, on somebody else’s risk
Language, interpreting and transcription services
Professional translation, court and conference interpreting, sworn translation and transcription across South Africa’s official languages.
- Why Pretoria
- This is the standout in Group A. South Africa has twelve official languages and a constitutional and statutory requirement to operate in them. The courts, national departments, embassies and universities all buy language services here, and the supply of properly accredited practitioners is thin, particularly in the less commercially served languages
- Capital
- R80,000 – R250,000. The lowest capital-to-margin ratio in this guide: the asset is accreditation and a network of vetted linguists
- Revenue model
- Per-word translation, per-day interpreting, per-audio-hour transcription, with panel appointments providing predictable volume
- Gross margin
- 50–60% operating as an agency over a freelance panel
- Key risk
- Quality control across freelancers, and the fact that sworn and court work requires individually accredited people you must recruit and retain
- Compliance
- South African Translators’ Institute accreditation for practitioners, sworn translator status conferred through the High Court, court interpreter accreditation, CSD registration for public work
- First contract
- Build the freelance panel first and get two or three practitioners individually accredited. Then approach departmental and university language units, which maintain standing panels and struggle to fill them
