Where to Park Business Cash: Notice Accounts, Term Deposits & the Working-Capital Balance

South African businesses hold enormous sums in current accounts earning nothing — cash that could be earning real interest in business notice accounts and term deposits. But business cash is not household savings: it has a prior claim on it called working capital, and the business that locks away money its stock cycle needs has traded interest for a cash-flow crisis. This guide covers the business deposit shelf — notice accounts, term deposits, money market options — and the layering discipline that earns yield on surplus without starving the operation.

The first question: is it actually surplus?

Before any deposit product, run the working-capital test. Cash in a business funds the gap between paying suppliers and being paid by customers — the cycle our trade-credit and business-funding guides map — and the first uses of spare cash often out-earn any deposit: early-settlement discounts from suppliers (a standard 2.5%-for-quick-payment discount annualises above 40% — no deposit competes); stock bought ahead of a proven season; and the buffer that avoids expensive borrowing (cash that saves you from an overdraft or merchant cash advance earns the avoided interest rate, which is far above deposit rates). Only money that clears these tests — genuinely surplus over a known horizon, after an honest cash-flow forecast including the slow season — belongs in deposit products. The classic error is the profitable business that locks a term deposit in March and takes expensive funding in June; the deposit rate earned was a fraction of the funding rate paid.

The business deposit shelf

The current account float. The operating layer — whatever your monthly cycle genuinely turns over stays here, instantly available. Most business current accounts pay little or nothing on balances, which is the whole reason to keep this layer no larger than the cycle needs.

Business notice accounts. The buffer layer: typically 32 days' notice to withdraw (some banks offer shorter and longer variants), paying a meaningful premium over current-account rates. Every major bank runs business notice products — Standard Bank's business notice account is among the commonly searched — and the notice period suits money whose need announces itself: the provisional tax payment (whose dates you know months ahead, per our tax guides), the annual insurance premium, the planned equipment purchase. The discipline mirrors personal notice accounts: give notice the moment a need appears on the horizon, and the money arrives before the bill does.

Business term/fixed deposits. The surplus layer: locked for a chosen term at the highest guaranteed business rates. Rates broadly track the personal fixed-deposit market our comparisons cover — leadership rotates between banks, terms from one month to five years, and effective-versus-nominal comparison discipline applies identically (get the rand maturity value on your amount and term from at least two banks). Reserved strictly for cash the forecast says the business cannot need before maturity.

Money market accounts and funds. The in-between option — generally better rates than current accounts with same-or-next-day access, suited to larger balances that need flexibility. As with all of these, the business versions of the products follow the personal versions' logic, at business-account pricing.

The layering, worked

A business holding R500,000 with a R150,000 monthly cost base might layer: R150,000 in the current account (one month's operating float); R200,000 in a 32-day business notice account (the genuine buffer — reachable on the notice period, earning the premium); and R150,000 in a 3-to-6-month business term deposit — but ONLY after the forecast confirms the slow season doesn't need it, and only after the supplier-discount arithmetic above has first claim. At current market rates, the layered R350,000 of non-float cash plausibly earns R25,000–R30,000 a year that the all-in-current-account version forfeits — real money for the ten minutes of setup, and the same three-layer architecture our personal savings guides teach, translated to business scale. Two business-specific notes: deposits at registered banks fall under the deposit insurance framework within its limits (worth checking how business deposits are treated for your bank and structure), and interest earned is ordinary business income for tax — the deposit interest lands in the company's taxable income, a bookkeeping line your accountant handles, not a reason to avoid earning it.

Setting it up — and keeping it honest

The practical sequence: build the 12-month cash-flow forecast first (the slow season, tax dates, planned capex — the forecast IS the product choice); price the notice and term options at your own bank AND one competitor (business deposit rates are negotiable at scale — six-figure balances should always ask for better than the sheet rate); automate the discipline (a monthly sweep of genuine surplus from current to notice keeps the float honest); and diarise every maturity for an active decision, because auto-rollover at sheet rates is where business deposits quietly underperform. Review quarterly against the working-capital reality — the layering serves the business, never the reverse. And if the business is cash-rich because it's between opportunities, remember the other side of this site's business guides: surplus cash funding growth (stock, equipment via the asset-finance comparison, a location) at business returns usually beats any deposit — the deposits are for cash whose best use hasn't arrived yet.

The mistakes that cost businesses the most

Four patterns recur in badly-parked business cash, and each has a cheap fix. The all-float error — everything in the current account for convenience — costs the full deposit yield on the non-float layers; the monthly sweep fixes it permanently. The over-lock error — its mirror — puts cycle money into term deposits chasing rate, then breaks the deposit (forfeiting interest and often paying penalties) or borrows expensively when the slow season arrives; the 12-month forecast prevents it. The auto-rollover drift — maturities rolling at sheet rates year after year — quietly bleeds the premium negotiation would have won; the maturity diary fixes it. And the personal-account shortcut — parking company money in the owner's personal savings account for the better advertised rate — creates loan-account tax complications, muddies the audit trail and pierces the separation between owner and company that clean bookkeeping (and any future funding application, per our business-loan guides) depends on; keep business cash in business-named products and let your accountant see every line. A quarterly twenty-minute review — forecast still right, layers still sized, rates still competitive — catches all four before they cost real money.

Frequently asked questions

What is a business notice account?

A business savings account requiring notice — typically 32 days — before withdrawal, in exchange for a better rate than current accounts pay. It suits the business buffer: money whose need announces itself ahead of time, like tax payments and planned purchases.

Can a business open a fixed deposit?

Yes — all major banks offer business term deposits, with rates broadly tracking the personal fixed-deposit market. Lock only cash your 12-month forecast confirms is surplus, compare rand maturity values across at least two banks, and negotiate at scale.

How much cash should a business keep accessible?

At minimum the operating float (roughly a month's cost base in the current account) plus a buffer in notice deposits sized to the slow season and known lumpy costs. Locking money the stock cycle needs converts deposit interest into expensive borrowing later.

Is deposit interest better than supplier early-settlement discounts?

Almost never — a standard 2.5% discount for early payment annualises above 40%, several times any deposit rate. Take the discounts your cash can fund first; deposit the surplus that remains.

Are business deposits covered by deposit insurance?

Qualifying deposits at registered South African banks fall under the deposit insurance framework within its coverage limits — check how your bank and business structure are treated, and spread very large balances across institutions as basic hygiene.
