Building a landed-cost and local price waterfall.

Project Atlas · Field guide 04 · Reviewed 21 July 2026

The fastest way to misprice a product in a new market is to take the export price and add a round-number markup. A landed-cost and price waterfall does the opposite: it builds the price from the ground up, one layer at a time, so you can see exactly where the money goes and whether anything is left as margin. This guide walks through the layers and works a fully illustrative example in rand.

Why a waterfall, not a markup

A markup hides the parts of the cost that vary most between markets — freight, duties, clearing, fulfilment and channel fees. A waterfall exposes them. It starts at the factory price and flows downward through every cost the product picks up on the way to a South African customer, ending at the margin that remains. Building it before you commit stock answers the only question that matters at this stage: at a realistic local shelf price, does this product still make money after every layer is paid?

The layers, from FOB to margin

Most waterfalls follow the same order. FOB is the free-on-board factory or port price — the starting point. Freight and insurance move the goods to South Africa. Duties and import VAT are assessed on arrival. Clearing and handling cover the customs broker and port costs. Warehousing and fulfilment add receiving, storage, and pick-pack-and-materials per order. Channel fees are the marketplace's cut. What is left, after subtracting all of that from the net selling price, is margin. Each layer is a lever: change the Incoterm, the freight mode, the channel or the packaging and the number at the bottom moves.

Under the SmartWarehouse pilot model, the manufacturer funds the approved pilot inventory and its inbound movement to the agreed South African handover point. SmartWarehouse does not buy speculative launch stock upfront. The signed Supplier Agreement separately fixes who books freight, the Incoterm, importer of record, duties, taxes, compliance costs, insurance and risk transfer; those responsibilities must be reflected in the waterfall before stock moves.

Duties and the 15% import VAT

Two charges land at the border. The first is customs duty, set by the product's tariff code. Many finished-electronics tariff lines carry a 0% import duty, but this is category-specific and must be confirmed for each product — do not assume it. The second is import VAT at 15%, and this applies regardless of the duty rate. It is levied on the added-tax value: the customs value, plus a notional 10% uplift, plus any non-rebated duty. Crucially, import VAT is recoverable. The party in whose name the bill of entry is held claims it back as an input credit, so it is a cash-flow item rather than a permanent cost. For that reason a clean waterfall builds on VAT-exclusive costs and adds 15% output VAT only at the selling-price line.

Channel fees change the maths

Marketplace fees are often the largest single deduction after the product cost itself, and they differ by platform. Takealot charges a monthly seller subscription of around R400 and a category-based success fee that runs roughly 4% to 15% of the VAT-inclusive selling price, with electronics at the lower end; Fulfilment by Takealot adds a per-unit fee that scales with size and weight, and storage is free at up to 35 days of cover. Amazon South Africa charges a category-based referral fee that is normally 8% to 20%, but is running a promotional flat 5% until 31 March 2027, alongside a Professional plan discounted to R1 per month over the same period; its FBA fulfilment runs from about R27 per unit for the smallest items upward, with storage waived until 31 March 2026. Because these fees are levied on the selling price, they must be modelled as a percentage of the price you set, not a fixed cost.

An illustrative worked example

The table below builds a waterfall for a fictional, generic compact wireless device sold through a marketplace. Every figure is invented for illustration; the point is the structure, not the numbers.

Illustrative figures for a fictional, generic product. Not a quote, a benchmark, or a claim about any real product's costs. Memo: import VAT of 15% on the added-tax value (about R759 here) is roughly R113.85, paid at entry and recovered as an input credit, so it is excluded from the cost stack above. The example simplifies VAT charged on channel fees and excludes returns handling, marketing and payment-gateway costs. Duty is tariff-code specific — confirm your product's rate with SARS.

What the example shows

At a R1,499 shelf price the device returns about R304 of contribution margin per unit, a little under a quarter of net revenue. Two things stand out. First, VAT and the channel fee together remove roughly R345 before any product cost is counted — which is why the selling channel is a pricing decision, not just a distribution one. Second, the fully loaded cost of R790 leaves little room to absorb a lower shelf price or a higher-fee category; drop the price to R1,199 and the margin roughly halves. A waterfall makes those trade-offs visible before stock is on the water, when they are still cheap to change.

Common mistakes

• Treating import VAT as a cost. It is recoverable by the importer of record and should sit outside the margin calculation.
• Assuming a duty rate. Confirm the tariff code; a wrong assumption can move the whole waterfall.
• Modelling channel fees as fixed rand rather than a percentage of the price you set.
• Forgetting returns. The Consumer Protection Act allows defective-goods returns for six months, and that cost belongs in the plan.
• Pricing to a single channel. The same product carries different fees on Takealot, Amazon and a direct store.

A duty-deferral option exists — a licensed customs or bonded storage warehouse can postpone duty and import VAT while goods sit in bond — but it requires its own SARS licence and surety and is usually a later-phase optimisation, not a starting structure. Early on, most brands pay duty and VAT on entry into an ordinary warehouse and recover the input VAT.
