Q3 pays for Q4. Merchants use that line because the season's cash problem is structural: the biggest buy of the year leaves your account in August and September, the revenue doesn't arrive until late November and December, and January is when the two finally meet. A holiday cash calendar makes that gap visible month by month (deposit, balance, freight and duty, revenue, reset), so the quarter gets funded by plan instead of by overdraft. This is the seasonal edition; the general forward-looking version of the artifact is covered in the cash flow calendar guide, and this article is the Q3-to-Q4 version, with its specific dates and traps.
Why the holiday buy breaks the normal rhythm
An ordinary month runs a short loop: buy, sell within weeks, cash returns through the payout cycle (Shopify documents payout timing in its payments Help Center, accessed November 2026). The holiday buy breaks every leg of that loop at once. The purchase is larger than any other quarter's, suppliers want deposits months before shipping, the stock sits for 60–120 days before it sells, and the revenue compresses into roughly six weeks. Meanwhile October, after the balances are paid and before the revenue starts, is usually the cash trough of the entire year. Merchants who fund the season from the same bank balance that pays September's bills discover the trough the hard way; the calendar exists so you discover it in August, on paper, while there's still time to narrow the buy.
The six dates that build the calendar
Six dates, worked backward from the selling window:
- Deposit date: the day you place the order and the first cash leaves.
- Balance date: the final payment, often required before shipment; ask for the schedule up front.
- Ship date: when goods leave the factory, which fixes your mode choice.
- Sellable date: arrival plus receiving plus counts; stock that isn't sellable on Black Friday week doesn't count.
- Revenue start — Black Friday falls on November 27, 2026, and serious selling begins a week earlier.
- Reset date: early January, when leftovers, returns, and the spring rebuy get decided.
The backward arithmetic, illustrative: you want SKUs sellable by November 13, one week before revenue starts. Receiving takes 2 days, so goods arrive November 11. Your padded lead time on the ocean route is 45 days, so the PO goes out by September 27 — and the deposit leaves the same day. For any supplier without a history with you, widen the padding first; the estimation method for a first order is in the new-supplier lead-time guide. The stock-side planning for the weekend itself (quantities, cover, count cadence) is a separate job with its own guide; this article stays on the cash. Sizing the buy that cash has to fund is scenario work — the what-if buy plan prices the bad, base, and good versions of the same PO.
The worked calendar: deposit to January
Worked example, all figures estimated and illustrative: a store carrying roasted coffee gift tins (BEAN-ETH-250) and small pet carriers (CARRIER-S-01) plans a holiday buy at cost of $46,000: $28,000 in carriers, $18,000 in coffee.
| Month | Cash out | Cash in | Running gap vs. baseline |
|---|---|---|---|
| August | Deposit 30%: $13,800 (estimated) | normal trading | −$13,800 |
| September | Balance: $32,200 (estimated) | normal trading | −$46,000 |
| October | Freight + duty: $3,900 (estimated) | normal trading | −$49,900 |
| November | — | holiday revenue collected: $41,000 (estimated) | −$8,900 |
| December | — | holiday revenue collected: $52,000 (estimated) | +$43,100 |
| January | Spring rebuy: $9,500 (estimated) | post-holiday sales, net of returns | ≈ +$30,000 |
The number to stare at is $49,900 (estimated): the cash that leaves before a single holiday dollar returns. That's the funding problem in one figure, and it's why the deposit terms matter as much as the purchase terms: stretching the balance into October or negotiating staged payments moves the trough without changing the total.
Two lines deserve their own attention. Freight is usually quoted separately from the buy, so it lands in October's cash-out even though the goods left in September. And duty is a real line now: as of November 2026, the US duty-free de minimis exemption is suspended — Executive Order 14324 suspended it on July 30, 2025, EO 14388 continued the suspension on February 20, 2026, and statutory repeal takes effect July 1, 2027 (Executive Orders 14324 and 14388; CBP guidance, accessed November 2026). An imported holiday buy priced off a 2024-era plan is missing a line item that no longer rounds to zero.
The October checkpoint
One fixed week in October, three checks. First, sellable dates versus the calendar: run a count so November trading starts from real numbers — native counts carry a planned date, not a recurrence, so the cadence is a calendar entry you own — because phantom units in October become missing revenue in November. Second, supplier slippage: compare actual ship dates against the plan and re-derive the sellable date for anything that moved. Third, the late-container decision, which is arithmetic rather than panic: air-freighting a 300-unit top-up of CARRIER-S-01 carries an estimated $2,100 premium (illustrative), while the estimated contribution of those units during BFCM week is $5,400 (illustrative); if the units would otherwise miss the window entirely, fly them. The per-SKU leakage math behind that comparison is in the guide to what running out costs.
If the cash isn't there
Work the reductions in order. Cut depth on the tail before breadth on bestsellers: a carrier color you stock 20-deep hurts less than the bestseller missing from the shelf. Split purchase orders: deposit now, release production later, which stretches cash-out across more weeks. Move one route from ocean to air for a small early tranche of the top seller, accepting the premium as the price of keeping the revenue date. And shrink protection deliberately rather than accidentally: lower the accepted run-out risk on B and C classes explicitly instead of trimming bestsellers invisibly. What you avoid: borrowing against hope. If financing enters the picture, size it against the October trough from the calendar (not against the purchase total) and match repayment to when December revenue actually collects.
January: the reset that funds next year
January closes the loop. Count what's left, then decide each leftover's fate (markdown, bundle, or hold for next season) before the spring rebuy competes for the same cash. The evaluation line of your own calendar, December collections minus the full seasonal outlay, is the first input to next year's holiday budget: it tells you which category earned its capital (in the worked example, whether coffee or carriers turned faster) and which one gets a smaller deposit in August. Stores that skip the January reset rebuy their mistakes at full price.
Common questions
When should I order holiday inventory? Work backward from a sellable date one to two weeks before Black Friday: take November 13 as an illustrative target, subtract your receiving days, then subtract your padded lead time: 45 days for an ocean route gives a late-September order date. Domestic suppliers compress the calendar; overseas suppliers without a track record widen it.
How much cash does the holiday buy require? More than the purchase orders show: the buy at cost, plus freight and duty, plus the deposit-timing gap: cash that leaves before revenue returns. In the worked calendar above, a $46,000 buy put $49,900 out the door before the first holiday dollar came back (all estimated). Build your own six-month table rather than trusting a single purchase total.
Should I borrow to fund the holiday buy? Only after sequencing fails. Cutting tail depth, splitting purchase orders, and negotiating deposit schedules fund most buys without interest. If you do borrow, size the facility against the October trough in your calendar (not the purchase total) and confirm repayment matches when December revenue actually collects, not when the quarter ends.
What if my holiday container arrives late? Run the October checkpoint math: compare the air-freight premium for a partial top-up against the estimated contribution of the units that would otherwise miss the selling window. If the window is BFCM week and the contribution clears the premium with room to spare, fly the top-up; if the gap is marginal, protect bestsellers only and accept the tail.
Why does January matter for the holiday budget? Because it closes the loop: December collections minus the full seasonal outlay is your true holiday return, and it becomes the first input to next year's buy. January is also when leftovers get decided (markdown, bundle, or hold) and when the spring rebuy is sized, so an unplanned January can undo a well-funded Q4.
Next step
Draw the six-row table this week with your own buy numbers, from deposit month through January, and write the backward-dated order deadline at the top of your planning doc. The weekend-side stock planning is in the BFCM inventory planning guide, and the ceiling that decides how big the buy can be is in the inventory budget guide.
