The verdict in three sentences
In Sandton, a website for a wealth management firm or multi-family office usually costs 5 000 to 30 000+ USD from a Johannesburg agency, a 2026 ballpark based on public rate cards of Gauteng agencies and Clutch listings, with the top of the range reserved for agencies that also serve banks and listed asset managers. Kolonell delivers on a fixed international grid: 2 900 USD Starter, 4 900 USD Growth, 8 900 USD Premium, copywriting and 3 months of support included, in 3 to 4 weeks. For a Sandton COO, the useful question is less the headline price than supplier due diligence and the three-year cost, and that is where quotes differ most.
What do Johannesburg agencies charge a Sandton wealth firm in 2026?
Sandton concentrates the head offices of banks, the stock exchange, private banks and dozens of independent wealth managers and family offices along Rivonia Road and around Nelson Mandela Square. Agencies that work for this crowd know it, and price accordingly: proposals often include discovery workshops, brand work and a monthly retainer. Smaller studios in Rosebank, Braamfontein or Parkhurst are more affordable. The figures below are wide 2026 ballparks converted from rand, varying strongly with scope.
| Option | Indicative build price | Billing | Usual timeline | What is often missing |
|---|---|---|---|---|
| Large Sandton / Johannesburg agency | 12 000 to 30 000+ USD | rand, phased, retainer | 8 to 14 weeks | fixed scope, copywriting sometimes extra |
| Mid-size Gauteng studio | 5 000 to 12 000 USD | rand, fixed fee | 6 to 10 weeks | support after launch |
| Freelancer | 1 500 to 6 000 USD | rand, fixed fee | variable | process, backup if unavailable |
| Kolonell Starter | 2 900 USD | USD, fixed | 3 to 4 weeks | client login (quoted on request) |
| Kolonell Growth | 4 900 USD | USD, fixed | 3 to 4 weeks | client login (quoted on request) |
| Kolonell Premium | 8 900 USD | USD, fixed | usually 4 to 6 weeks, written schedule | client login (quoted on request) |
Kolonell's project manager works from Senegal (GMT), two hours behind Johannesburg, so a 10:00 Google Meet in Sandton is 08:00 for the team. You get a written update every week, native English copywriting, the domain in your name and every access handed over at delivery. Payment is by bank transfer or Wise: 50 % to start, 50 % at delivery. Details are on the international website offer page.
Supplier due diligence: what a Sandton compliance team will ask
Wealth firms in Sandton often run a light supplier review before signing, even for a website. Use the same checklist for every quote, local or remote.
| Question | Why it matters | Kolonell answer |
|---|---|---|
| Who owns the domain and hosting accounts? | lock-in risk, continuity | registered in your name, all access handed over |
| Where is the site hosted and where does form data go? | POPIA conditions on personal information and cross-border flows | documented in writing before launch |
| Who writes the content? | accuracy, compliance review workload | native English copywriting included, reviewed by your compliance officer |
| What happens after launch? | security updates, small changes | 3 months included (6 on Premium), maintenance then quoted |
| Is the price fixed? | budget control | fixed grid, scope written in the quote |
| Is a client portal included? | security, separate risk review | no, custom application quoted on request |
| What references can we check? | supplier credibility | TR Signing Group and Orven Properties, public sites |
Those two references are real and public: the bilingual EN/FR site of TR Signing Group (trsigninggroup.com), notary and apostille services in New Jersey, with file-by-file quote verification, a booking calendar and a back office; and the trilingual FR/EN/AR site of Orven Properties (orvenproperties.com), off-plan real-estate advisory in Dubai. Kolonell does not claim South African clients it does not have.
What a Sandton wealth management website needs
Sobriety and discretion. No client names, no performance or return figures, no assets under management unless your annual disclosures already publish them. Present the partners, the investment committee, the governance and the services (wealth planning, investment advisory, estate and succession, offshore structuring explained in general terms, philanthropy) without anything that reads as advice.
Languages of Gauteng. English is the working language of Sandton finance. Some firms add a short isiZulu, Sesotho or Afrikaans welcome text to reflect their client base and staff; Kolonell writes English and French natively, other languages are supplied by you or quoted separately. A French version (Premium) helps firms serving francophone African families who bank in Johannesburg.
Regulation and data. Financial services providers in South Africa fall under the FSCA, and financial marketing rules apply depending on your licence and categories: your compliance officer must validate every page. Personal information collected by forms, newsletters and analytics falls under POPIA, overseen by the Information Regulator. This is factual context, not legal advice.
Family offices that take no clients. A single family office in Sandton may want only a discreet page for counterparties and recruitment. Starter at 2 900 USD fits that need without overspending.

Mini case study
*Illustrative example, hypothetical persona.* Thabo is COO of a Sandton multi-family office. He has three proposals: a large agency at 22 000 USD plus a 400 USD monthly retainer, a Rosebank studio at 8 000 USD plus 200 USD a month, and Kolonell Premium at 8 900 USD (bilingual EN/FR, which he needs for clients from Kinshasa and Abidjan). Three-year totals: large agency 22 000 + 400 x 36 = 36 400 USD; studio 8 000 + 200 x 36 = 15 200 USD; Kolonell 8 900 + 6 months support included, then, as a working assumption to be confirmed in a maintenance quote, 200 USD a month for 30 months = 14 900 USD. The studio and Kolonell land close; the deciding factors become the included French version, the copywriting and the timeline (4 to 6 weeks versus 6 to 10).
FAQ
Why do some Sandton agencies quote above 20 000 USD?
Their proposals often bundle brand strategy, discovery workshops and a retainer, and they serve banks and listed firms. For a 6 to 12 page firm website, a 2026 ballpark of 5 000 to 12 000 USD at a mid-size studio is common.
Do you invoice in rand?
No, Kolonell invoices in USD: 2 900, 4 900 or 8 900 USD. You can pay by bank transfer or Wise, in two instalments of 50 %.
Can the site handle POPIA consent properly?
Yes, forms, cookie consent and the privacy notice are built in, and the hosting location is documented. Your own legal or compliance team validates the wording; this is not legal advice.
Can you add an investor reporting portal later?
Yes, as a separate custom application quoted on request. Keeping it outside the 4 900 USD Growth site lets you launch the public site in 3 to 4 weeks.
What if our compliance review takes longer?
The schedule includes a review round; if it runs over, delivery moves with it, with no extra fee for waiting.
