Reading Your Own Seasonal Pattern
Compare matched weeks or months across prior years and adjacent periods. Use delivered-order revenue: 120 delivered orders = $18,000 ($150 each); 150 = $19,500, so orders rose 25% but revenue 8.3%, indicating lower order value or changed mix. Break down category, product and collection; check whether revenue growth is offset by costs or returns, tracking return units and refund value against revenue and the original period where possible. Record first-order timing to distinguish new from existing customers. Use revenue, orders, mix, returns and timing to choose actions. ORVX connects to Shopify, shows product-, collection- and customer-level profitability and contribution after advertising, and keeps currencies separate.
Turning Demand Patterns Into a Working Calendar
Turn each observed demand peak into a backward calendar. Mark the weeks when delivered orders actually rose, then work back to the latest date for buying, production, inbound delivery, photography, launch and markdown decisions. For illustration only, a peak in the week of November 20 might require a collection launch in late October, delivery to your warehouse earlier, production before that, and buying still earlier. These are planning dates, not sales dates.
Keep the measures separate. The sales calendar records when customers ordered and when revenue was realized; the operations calendar records when stock and creative must be ready. Use delivered orders for the sales signal, since cancellations and returns should not be treated as revenue. ORVX calculates realized revenue from delivered orders only and can show remaining stock value and dead stock, helping distinguish a weak launch from a timing problem.
Set a decision gate beside each peak: confirm the buy, lock production, verify delivery, launch, then review the sell-through signal before markdowns. A markdown date should respond to remaining stock and profitability, not simply arrive because a promotion was scheduled. Product-level and collection-level profitability shows whether reducing price is economically justified.
| Calendar entry | What it answers | When to act |
|---|---|---|
| Sales date | When demand and delivered revenue appear | Measure the observed peak |
| Buying date | When quantities and styles must be committed | Before production lead time |
| Production and delivery dates | When goods must be made and available | Before launch |
| Launch date | When customers first see the offer | Ahead of the sales peak |
| Markdown date | When remaining stock warrants a price decision | After reviewing stock and profitability |
Worked example with sample numbers
This example is illustrative. It uses sample numbers for a men's fashion store selling in the US. 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.
| Month type | Orders | Stock cost to fund | Margin earned |
|---|---|---|---|
| Quiet | 253 | $4580.80 | $7212.13 |
| Busy | 405 | $7332.90 | $11545.11 |
| Peak | 607 | $10990.29 | $17303.40 |

Planning Stock Before the Peak
Plan at product-size level, not just by style. For each SKU, estimate peak units by size, subtract confirmed stock and open purchase orders, then set the buy quantity. A 120-unit jacket plan with 18 units already available requires 102 additional units before any safety stock.
Use the supplier’s latest realistic lead time, including production, freight and receiving. Safety stock should cover uncertainty during that window, not compensate for an unsupported demand guess. For illustration only, if expected demand during lead time is 80 units and the chosen buffer is 20, the reorder point is 100 units.
Check sell-through by SKU and size as deliveries arrive. Sell-through tells you whether to reorder, hold, or reduce exposure; gross profit and contribution after advertising tell you whether that volume is economically useful. Overbuying also ties up cash: 40 leftover units at a $35 product cost leave $1,400 invested, before markdowns or storage.
ORVX reports inventory position, dead stock and remaining stock value alongside product and collection profitability. Use those measures to identify slow sizes and expensive leftovers; use the inventory reorder calculator to test the unit arithmetic before placing a buy.
| SKU / size | Peak plan | Available | Lead-time demand | Safety stock | Suggested buy |
|---|---|---|---|---|---|
| Jacket / M | 40 | 6 | 28 | 7 | 41 |
| Jacket / L | 32 | 4 | 24 | 6 | 34 |
| Trouser / 32 | 24 | 8 | 16 | 4 | 20 |
Protecting Cash Through the Season
Build a weekly cash schedule separating committed payments from likely receipts. Include supplier deposits and balances, freight, payroll, tax, payment fees and planned ad invoices, with expected customer receipts beside them. A $20,000 supplier balance due before a $14,000 receipts week leaves a $6,000 funding gap, even if the season is profitable on paper. Before committing stock or promotion, compare cash coverage (can the business pay on time?), gross margin (does each sale cover product cost?) and contribution after advertising (does marketing leave useful cash after acquisition spend?). Act on cash coverage when dates do not line up; use contribution to choose products or collections for further promotion. Model discounts and returns in a downside case: sale price after markdown, expected refund value and returned-stock timing. ORVX calculates realized revenue from delivered orders, reports refund value and return rate, and shows remaining stock value and dead stock. Cap commitments using these figures, then fund marketing only from the cash the schedule leaves available.
Setting Ad Budgets Across the Year
Set each period’s ad budget against contribution, not revenue or attributed ROAS alone. For illustration only, a $100 delivered order less $35 product cost, $12 fulfilment, $10 discounts and $8 expected returns leaves $35 before advertising. With $15 ad spend, contribution after advertising is $20; $35 is the break-even ceiling for that order’s ad cost. Use delivered orders only, because cancelled and returned orders should not inflate the revenue base.
Increase budget when additional spend continues to produce positive contribution after these costs and returns remain within your operating assumptions. Hold when contribution is positive but close to break-even, or when attribution is too uncertain to justify more risk. Reduce when ad spend exceeds contribution, or when discounting and returns erase the apparent gain. MER, total revenue divided by total ad spend, is suited to deciding whether the whole paid-media budget is working. Attributed ROAS is suited to comparing reported channel or campaign credit; it should not replace the full-store profitability check. ORVX keeps these measures separate and reports contribution after advertising by product and collection, alongside product- and collection-level profitability.
What to Review After the Peak
After the peak, compare forecast with delivered sales, separating timing, units, mix and price; reconcile units sold, size-level stock, commitments and stock value. Distinguish a miss with excess stock from a hit with unavailable sizes. Review gross margin and contribution after advertising; revenue growth is unhelpful if discounts, product cost, fulfilment or ads absorb it. Review returns, acquisition and channel delivered revenue, contribution and spend, using MER and attributed ROAS separately. Follow the worked example in that order and act on the indicated stock, margin, returns or channel issue. ORVX reports these measures from connected Shopify and advertising data; it never acts on the store.
A seasonal plan should connect the demand pattern in your own order history with the stock, cash and advertising decisions required before each peak. Review the plan after the period ends, keep the measures that support a clear action, and revise the next calendar using actual results rather than assumptions.
