The trust ledger: how Ford SA earns its marketing budget

Ford has built vehicles in South Africa since 1923, and its buying cycles run five to seven years, so brand investment made today only pays off years out. That's exactly the kind of spend a nervous finance team resists. Here's how Tarryn keeps them onside.

Trust is a bank account

"It's actually what you do in every little day. Am I managing my marketing fleet closely? Do I respect the governance principles of my role? Am I working well with legal and procurement? If you do those things with excellence, then when you have a bigger conversation — can we tap into extra budget — there's trust to support a business case."

Treat organisational trust like an account with deposits and withdrawals.

Daily deposits: clean budget admin, accurate forecasts, governance respected, deadlines met, legal and procurement treated as colleagues rather than obstacles.

Cycle deposits: close every initiative with a simple loop — we asked, we promised, we delivered. Stated out loud, in the business's language. Each cycle of promise-and-proof is a deposit. Then, as Tarryn puts it: "Hi, we're here to ask again."

Withdrawals: brave creative, off-cycle asks, long-horizon brand bets. These only clear if the account is in credit.

Make the CFO a stakeholder, not an obstacle

Tarryn's second move is to treat finance's constraints as her own. Her sessions with the CFO cover what marketing is trying to achieve short, medium and long term — and, crucially, she engages with what finance is measured on: EBIT targets and forecasting accuracy. Marketing forecasting its own spend accurately is itself a trust-builder. "The whole thing works together."

The shift, in the podcast's words, is from being the petulant child asking for more pocket money to being a genuine partner. And in her experience, the C-suite has become genuinely more open to brand investment — but only for marketers who've done the everyday work first.

The overdraft rule

There's a hard edge to this. Tarryn and I landed on it together in the episode: if the idea of doing every small thing with excellence — the fleet admin, the governance, the attention to detail — scares you, then leadership might not be the right ambition. Being a brilliant specialist is a perfectly good career. But the seat comes with the ledger.

The same logic runs outward, to the market. Ford is a global brand, and Tarryn holds the local line with a phrase she inherited: "as global as possible, but as local as necessary." But local storytelling has an entry requirement — you've earned the right to tell a South African story only because you've genuinely invested here: the Wildlife Foundation, the CSI projects, the jobs. The parachuted-in brand with borrowed slang and no receipts "sticks out like a sore thumb," and audiences punish it.

Try this week: list your last three asks of the business. Did you close the loop on each with delivered proof? If not, do it now — retroactively counts. Then find out what your CFO is personally measured on, and put it in your next budget conversation.

Trust with a CFO is built the same way it is with peers — slowly, in rooms. We mapped those rooms in a guide to SA marketing communities and associations.
