Reading Your Own Seasonal Pattern

Start with your own Shopify history, grouped by calendar month or by consistently defined trading periods. A trading period can align with a promotion or school-holiday window, but use the same start and end rules each time. Compare delivered orders and units first, then realized revenue and margin. ORVX calculates realized revenue from delivered orders only, excluding returned and cancelled orders, so the comparison is not inflated by sales that did not remain completed.

Read the measures together rather than treating revenue as demand. A month with more orders may produce fewer units per order; higher revenue may come with weaker margin if the product mix or discounts changed. ORVX computes product costs, gross profit and margins, and can show the result by product or collection. Keep GST treatment consistent in every period; New Zealand GST is charged at 15% (Inland Revenue (Te Tari Taake), GST) (Source: Inland Revenue (Te Tari Taake)).

Compare the Signals Before You Commit

Orders measure buying occasions, conversion and estimated transactions from a promotion, but basket size can mislead. Units better indicate demand and stock needs: 100 orders could mean 100 gloves or 250 individual items. Revenue measures sales value for comparing periods, collections and average order value; check whether it includes cancellations, returns, discounts or tax. ORVX calculates realized revenue from delivered orders only, excluding returned or cancelled orders. Contribution better informs scaling a product, collection or promotion: it shows what remains after relevant product costs and advertising. A $20,000 campaign producing $5,000 after those costs differs from one producing $9,000. Cash answers whether the business can meet supplier, payroll, tax and advertising payments when due. Use it before a purchase or promotion: revenue may be healthy while cash is tied in stock or delayed payouts.

Worked example with sample numbers

This example is illustrative. It uses sample numbers for a motorcycle gear store selling in New Zealand. They are made up to show the method, they are not a benchmark, and your own figures will differ.

Formula: Stock to fund = forecast orders x cost of goods per order.

Planning Stock Before the Peak

Plan stock by product: estimate demand by helmet size, jacket fit, glove size and seasonal category, allowing for supplier lead time. Opening stock covers peak-window sales plus a stated buffer; the reorder point triggers replenishment based on sales during the next shipment’s transit and chosen safety stock. Check supplier minimums, deposits, production slots and non-cancellable purchases against profitability and sell-through. ORVX reports remaining stock value and dead stock; the inventory reorder calculator structures the arithmetic. The worked example follows demand estimate, lead-time requirement, opening stock, reorder point and supplier commitment. Its figures demonstrate the method, not a benchmark; replace inputs with your SKU history, current inventory, delivery time and supplier terms.

Ad Budgets Across the Year

A calendar-based budget assigns spend by month or trading period, useful with limited history, a known promotion or fixed cash limit; reserve more where stronger riding demand is expected. Its weakness is repeating despite changes in product mix, margins or customer response.

A demand-and-contribution budget uses completed results: delivered revenue, product cost and advertising spend. $10,000 of delivered revenue minus $6,000 of product cost and $2,000 of ads leaves $2,000 before other operating costs. ORVX reports contribution after advertising by product and collection, alongside MER and attributed ROAS, so growth is not mistaken for profitable growth.

  • Increase spend for repeatable contribution, remaining stock and acceptable returns, supported by more than one comparable period.
  • Hold spend when demand is uneven, contribution is positive but uncertain, or MER and attributed ROAS differ; gather another period of evidence.
  • Reduce or stop when ads consume contribution, returns erode revenue, or stock is too limited. Use calendar allocation as a baseline; let prior contribution determine the adjustment.

Keep Stock and Cash Decisions Connected

Stock can be profitable on paper and still create a cash shortfall. A cash plan follows when money leaves or reaches the bank; a profit view follows when sales and costs are recognised. Keep both beside each other before committing to a seasonal buy.

For illustration only, a month with $24,000 in expected receipts produces $6,600 before other overheads: $24,000 − $12,000 inventory payments − $2,400 fulfilment − $3,000 advertising. That is not the same as gross profit, because the inventory payment may cover stock sold later. If receipts include GST, reserve the liability separately; Inland Revenue (Te Tari Taake) states that GST in New Zealand is charged at a rate of 15%. Use actual supplier due dates, delivery charges, ad payment dates and realistic receipt timing rather than monthly totals alone. ORVX reports inventory position, remaining stock value, realised revenue and advertising spend, and shows profitability, so you can check a large stock commitment against both cash pressure and product economics.

Sales receipts$24,000Inflow when customers pay
Fulfilment costs$2,400Outflow as orders are dispatched
Ad spend$3,000Outflow on the advertising payment date

What to Review After the Peak

After the peak, compare the plan with delivered orders, not just checkout volume. Orders show whether the buying occasion occurred; delivered orders show realised revenue after cancellations and returns. Compare planned units with actual units by helmet size, jacket fit and category, then review remaining stock, dead stock and stock value. A shortfall calls for a demand or availability diagnosis; excess stock calls for a slower replenishment plan or a clearance decision.

Reconcile planned and realised gross margin using product cost, then check contribution after advertising. Revenue can look strong while margin falls: $20,000 revenue at 45% gross margin produces $9,000 gross profit, but $3,000 advertising leaves $6,000 before other costs. Review cash timing separately, supplier payments, ad charges, customer receipts and refunds, because a profitable period can still strain the bank. Compare MER (total revenue ÷ total ad spend) with attributed ROAS (tracked ad revenue ÷ tracked spend); use MER for the whole business and ROAS for channel or campaign analysis. Record each variance and carry it into the next plan: change size-level stock, budget timing, promotion scope or a product’s scale, reduce, fix-economics, test or stop decision.

A workable seasonal plan is a repeatable comparison between your own trading periods, stock commitments, cash timing and advertising decisions. Keep the assumptions visible, separate demand from profitability, and revise the next plan using what actually happened.
