How to build a retail pricing waterfall

A pricing waterfall reads top to bottom, from the shelf price a shopper pays down to the net you keep per unit, subtracting each cost the channel takes on the way. You build it once per retailer, because each one takes a different margin and asks for different trade spend, so the same product can leave you a healthy net in one channel and a loss in another.

Begin with the recommended retail price, the shelf price including GST that the shopper sees. Strip the GST to get the ex-GST shelf price, because every trade number downstream works in ex-GST terms. That ex-GST figure is the top line of your waterfall and the number every deduction below is measured against, so getting it right sets the accuracy of everything that follows.

Work in a spreadsheet with one row per deduction and a running net on the right, so you can see exactly where the money goes. When a buyer asks you to move price or fund a promotion, you change one cell and watch the net move, which turns a tense negotiation into a modelled decision rather than a guess.

The first big deduction is retailer margin, the gross profit the retailer keeps between what it pays you and the ex-GST shelf price, which runs roughly 25 to 45 percent depending on category. Subtract it from the ex-GST shelf price and you reach the wholesale price, the amount the retailer actually pays you per unit before anything else comes off. This is your invoice price, and it is where most first-time suppliers stop counting, which is the mistake.

Next comes trade spend, the rebates, promotional funding and co-op you pay the retailer out of gross sales, which commonly runs 10 to 25 percent. It covers catalogue features, price-off promotions, a share of the retailer's marketing and volume rebates settled after the fact. Some is invoiced, some is deducted at source, but all of it comes off your wholesale price, so it belongs in the waterfall even though the timing varies.

Add chargebacks here too, the deductions a retailer takes for short or late deliveries, admin and compliance failures, typically 1 to 5 percent of invoice value. They are easy to forget because they are unpredictable, but a supplier missing DIFOT, delivered in full and on time, pays these routinely, so model them at a realistic rate rather than assuming zero.

After the retailer's cuts, subtract your own supply costs, starting with freight and warehousing: the cost to hold stock, pick and pack it, and deliver into the retailer's distribution centre on their terms. These are real per-unit costs whether you run your own warehouse or use a third-party logistics provider, and delivered-in pricing means you wear the freight to the DC, not the retailer, so it has to sit in the model.

Then subtract landed cost, the fully loaded cost to get one finished unit into your warehouse: manufacturing or purchase price, inbound freight, insurance, and for imported goods the customs duty and clearance your broker handles. For imported product, work from the landed figure your customs broker confirms, not the ex-factory price, because duty and freight can move landed cost by a wide margin and quietly erase a net you thought was safe.

What remains after all of this is your net per unit, the money you actually keep to cover overhead, product development and profit. If that number is thin but positive, you have a business to negotiate. If it is negative, no amount of volume fixes it, and that is the trap the next section covers.

The trap is simple and brutal: if your net per unit is negative, a successful listing loses more money, not less, because every extra unit sold deepens the loss. Founders assume scale rescues a thin margin, but a waterfall that ends below zero only compounds with volume, and a retailer that reorders well is now your fastest route to running out of cash.

It hides because the wholesale price looks fine in isolation. The damage is in the stack below it: 25 to 45 percent margin, then 10 to 25 percent trade spend, then chargebacks, then freight and landed cost, each reasonable alone but ruinous together. A product that clears a healthy net direct-to-consumer can land underwater in a major grocer once the full waterfall is built, which is exactly why you build it before you pitch.

The honest response to a negative bottom line is to fix the inputs before you chase the listing: raise shelf price, cut landed cost, renegotiate trade spend, or walk away from that channel. Sometimes the answer is not yet, and a buyer who ranges you into a loss has not done you a favour. Model the numbers first, because the buyer decides whether to list you, but only you decide whether the deal is worth taking.

Before you take a waterfall into a buyer meeting, stress it against how Australian retail actually behaves. Range reviews happen roughly every six months, so a promotional plan and its trade spend get locked in for a window you cannot easily revisit, and the first purchase order often lands one to six months after a ranging win, so model the cash gap, not just the unit economics.

Layer in the operational realities that touch the net: GS1 barcodes at unit, carton and pallet, EDI builds that take months before you can invoice cleanly, and the DIFOT and compliance standards that drive chargebacks. Supplements or therapeutic products carry claim rules that sit with TGA specialists, while Built for Retail runs the retail and fulfilment half; know which costs are yours to model and which need a specialist before you commit to a price.

Built for Retail has ranged brands as the supplier's agent into Chemist Warehouse, Woolworths, Coles and Priceline; past rangings never promise yours, because the buyer decides and no listing is guaranteed. The Retail-Readiness Sprint is a fixed fee of $15,000 for a single retailer, about four weeks, modelling your real trade spend, the pricing waterfall, the review calendar and the compliance gap. You keep the model, and sometimes its honest answer is not yet. Use the contact form on this page to start.
