DTC unit economics

DTC unit economics show what an order contributes after the costs of making and serving it, how much that contribution can support customer acquisition, and whether the business can meet its wider costs and payments. Start with representative orders, then check discounts, delivery destinations, returns and repeat purchases separately. Product margin alone cannot answer those questions.

Follow the money through an order

Assess the revenue an order retains and the costs of making and serving it. Consider product and delivery revenue, discounts, refunds, fulfilment and support, plus the possible effect of returns.

Order contribution before acquisition = retained order revenue − order-related costs. Keep acquisition spend in the next layer to see what the order itself contributes.

Keep the decisions separate

A positive order contribution does not establish that rent, salaries, software and other fixed commitments are covered. Stock and advertising payments may also be due before later customer revenue arrives. Keep a cash forecast alongside the unit model.

Use estimated sales and costs for each future period, then compare projected balances with payments due.

Key Metrics in DTC Unit Economics

Use more than one order case

Calculate a full-price single-item order, a discounted order, a multi-item order and a costly delivery destination where relevant. Include the delivery amount the customer pays and the carrier charge. A bundle may share one parcel charge but need different packing or have a different return pattern.

Use supplier terms and carrier quotes until actual records are available. Mark estimates and their dates. Keep fixed charges separate from per-order charges; if you allocate a shared cost across orders for planning, show the allocation method.

For returns, distinguish refunded revenue from additional freight, handling, replacement dispatch and lost product value.

Critical Inputs for DTC Unit Economics

Decide what acquisition can cost

For a first purchase, order contribution before acquisition is the break-even acquisition amount for that order before fixed costs and other cash needs. A working ceiling is lower when the first order must leave money for those needs. Compare that ceiling with the cost of gaining additional customers. An advertising dashboard's attributed orders may include people who would have bought anyway.

State the customer definition, time period and costs included. If the spending rule depends on a later order, show what happens when that order never arrives.

Turn contribution into a cash-timing check

Order contribution describes the economics of an order; a cash flow forecast estimates sales and costs in future periods. Use it to check whether expected income can cover payments when they fall due, and to identify possible shortages or surpluses before they occur.

Set the opening balance for the first forecast month to the opening bank balance. For each following month, carry forward the previous month's closing balance. Record incoming and outgoing cash in the period you expect it to arrive or be paid, rather than treating every sale or cost as cash in the same month.

Cash incoming can include sales, debtor receipts, grants and tax rebates. Outgoing cash can include purchases, advertising and marketing, accountant fees, rent and rates, and utilities. Consider when major costs are paid, not just their amount, and use previous years' figures to account for seasonal trends where available.

Add the period's incoming cash and subtract outgoing cash to find its monthly cash balance. Add that balance to the opening balance to find the closing balance. Label and explain estimates clearly, and state whether forecast figures include or exclude GST.

Building a Cash Flow Forecast for DTC Businesses

Treat repeat buying as evidence, not a promise

Repeat purchases may add contribution beyond the first order, but they are uncertain. Consider how product life, seasonality, availability and changes to the offer may affect whether past buying behaviour predicts future orders.

Use the model to find the cause of weak contribution: product cost, parcel size, delivery zone, discounts, returns or order mix. Recheck estimates against orders and invoices when they become available.
