Apparel buyers manage both seasonal commitments and replenishment of existing styles. The first depends on the assortment plan, supplier booking deadlines and delivery windows. The second depends on current stock and demand by size and color. Both need a reliable record of what was requested, accepted, received and still due.
This guide is for a boutique buyer or stocked apparel-brand operator managing supplier purchases. It focuses on size runs, seasonal buying budgets and split deliveries. For general retail purchasing, start with the retail workflow guide.
What makes apparel procurement different
Check these five requirements against your assortment and supplier terms:
Minimums may apply by style, color or size run. A white linen shirt is not one item from a wholesale brand's perspective. It is a matrix: Small, Medium, Large, XL in the same colorway — plus any additional colors the buyer wants to carry. A supplier may set minimums per size run or colorway, meaning a buyer who wants one color of one style must commit to a full size distribution to clear the minimum order quantity. A procurement system that tracks the shirt as a single SKU with one reorder point will misrepresent both what was ordered and what needs to be replenished.
Seasonal pre-buys are committed before demand is known. Pre-season orders can be placed months before delivery; deposit, cancellation and delivery obligations depend on the agreed contract. A boutique committing $40,000 in Spring/Summer pre-buys in October is working against a sales plan and historical trend, not actual sell-through. Before accepting the order, review what can be changed or canceled if demand differs from the plan.
Delivery can arrive in multiple waves. One supplier order may have several delivery windows. Track each receipt and the remaining quantity by variant. A received first shipment does not mean the whole order is complete.
Markdown exposure changes the reorder decision. Slow-selling sizes or colors can tie up budget even when the style sells well overall. Estimate remaining full-price demand, likely markdowns and carrying costs for your assortment. A category-wide holding-cost percentage does not establish the cost of a particular seasonal overbuy.
Imported stock needs a full cost comparison.Landed cost includes relevant freight, duty, insurance and handling in addition to the supplier price. Use shipment-specific inputs and the accounting team’s approved allocation policy.
Open-to-buy: the budget that must become purchase orders
An open-to-buy plan helps a buyer set a purchasing budget. One retail-value formulation, after allowing for existing incoming commitments, is:
OTB = Planned Sales + Planned EOM Stock + Planned Markdowns − BOM Stock − On Order
Use one valuation basis and one planning period throughout. In this formula, sales, markdowns, beginning-of-month (BOM) stock, end-of-month (EOM) stock and on-order commitments are all at retail value. Subtract only the relevant unreceived commitments not already included elsewhere in the plan. OTB at retail is not cash available to spend or purchase cost; converting to cost requires an appropriate cost-to-retail relationship. A boutique planning $120,000 in annual purchases uses OTB to allocate that budget by season, by category, and by vendor — ensuring a favorite brand's Fall collection does not consume budget needed for basics reordering in Q4.
The execution gap OTB creates: the formula tells you how much to buy. It does not tell you what happened to what you bought. Whether the pre-buy POs were confirmed by suppliers, when Wave 1 arrived, what was substituted, what the final received cost was after a price change, what AP should see — none of that is OTB. That is procurement execution.
A living PO connected to a pre-buy commitment tracks each delivery window as a separate receiving event. When Wave 1 of a Fall/Winter order arrives in early September — 44 units across three colorways — that event closes the first delivery window, updates on-hand inventory by variant, and surfaces the Wave 2 expected arrival. Accounting sees a partial receipt against the PO. The unreceived balance remains operationally on order. Finance determines recognition and valuation from the applicable terms and accounting policy; a receiving status alone does not determine ownership or expense.
Faire and the wholesale ordering channel
A boutique may use Faire alongside direct brand accounts. Confirm the payment and return terms for the particular order, including eligibility and exclusions, rather than assuming every order has the same credit or return policy.
It does not simplify receiving. A Faire order generates a physical shipment with a packing list, line items that may or may not match the order exactly, and an invoice that flows through Faire's system. A supplier may propose a substitute for a sold-out style; the buyer must review it. Shipments arrive in multiple cartons across multiple days. Receiving quantities sometimes differ from invoice quantities.
Those discrepancies belong on a living PO — captured upstream before accounting inherits the bill — not in a separate reconciliation process conducted from a Faire order history page.
For boutiques ordering from Faire and direct-wholesale brands simultaneously, the procurement challenge is a unified view: what is confirmed, what is in transit, what has been received, what has been invoiced, across all channels. A buyer who tracks Faire orders in one place and direct-brand orders in a spreadsheet has two partial pictures of their inventory position, not one.
Replenishment: basics, bestsellers, and the size-run constraint
Seasonal pre-buys are planned; replenishment is reactive. For apparel, replenishment applies to two categories with different mechanics.
Core basics — white tees, classic denim, everyday socks — may suit a reorder-point policy when their observed demand is sufficiently stable (run your own numbers with the reorder point calculator):
ROP = (consumption rate × lead time) + safety stock
For a white crew-neck tee selling 10 units per month, with an assumed fixed 14-day supplier lead time, a 30-day demand period and a monthly-demand standard deviation of 2.5 units, an illustrative normal approximation with z = 1.65 gives:
safety stock = 1.65 × 2.5 × √(14/30) ≈ 2.82 units → round up to 3
ROP = (10/30 × 14) + 3 ≈ 7.67 → round up to 8 units of inventory position
The model assumes independent demand increments and fixed lead time; z = 1.65 is a nominal cycle-service target, not a guarantee of achieved service. Compare the trigger with usable on-hand plus relevant incoming stock minus separate commitments, avoiding double-counted demand. Check arrival timing separately. The APICS safety-stock guide explains these modeling assumptions. A trigger does not establish how many units to buy. Blanket purchase orders for basics work well with domestic suppliers: a standing commitment for a seasonal quantity at a locked price, drawn down through individual releases when stock reaches the reorder point. The supplier gets volume predictability; the buyer gets price certainty across the season.
Bestseller replenishment is judgment-adjacent even when well-supported by data. A style tracking 160% of planned sell-through in Week 4 of the season is a candidate for a reorder — but only if: the brand has inventory remaining, the lead time allows delivery before the season ends, and the MOQ for the reorder is viable against the expected remaining sell-through. If the season has six weeks remaining, the goods will be usable at the store in two weeks, and the MOQ is 12 units, the decision is: will 12 units sell in four weeks at full price? That judgment belongs with the buyer. The procurement system handles the execution once the decision is made.
Size distribution in replenishment orders. Even when a style sells well in aggregate, the size distribution in replenishment may differ from the original buy. If the original size run was 2S / 4M / 4L / 2XL and Medium sold out first, the replenishment run might be 0S / 6M / 2L / 0XL. A system that only tracks the total quantity, not the size-level breakdown, will generate incorrect replenishment quantities.
Receiving apparel: variant accuracy, wave tracking, and substitutions
Apparel receiving has a complexity layer most procurement systems flatten: variant-level accuracy within a style shipment. When a carton of 12 shirts arrives — 2 Small, 4 Medium, 4 Large, 2 XL — the receiving event must capture those quantities at the variant level, not as 12 undifferentiated units.
Why variant-level receiving matters:
Inventory accuracy. If the system records "12 shirts" without capturing the size breakdown, the first sale of a Medium will draw down inventory incorrectly. Count discrepancies surface at physical inventory, not at the moment they are created.
Invoice reconciliation. Brands occasionally ship size allocations differently from what was invoiced — 3 Large shipped where the invoice says 4, with an adjustment note buried in the packing slip. Those differences belong on the living PO before the invoice is approved.
Substitution tracking. A brand that ships a substitute colorway for a sold-out one has made a change that affects every downstream record: inventory by color, expected margin per style, and recipe/BOM costing if the item is part of a gift set or bundle. Preserve the proposed substitute and the buyer’s acceptance separately. Receiving should identify the actual color and size, rather than silently adding it to the original variant.
Supplier communication around delivery — tracking numbers, wave arrival dates, partial-shipment notices — should update the living PO before the carton arrives. A buyer who knows Wave 2 is delayed three weeks can adjust in-season markdown timing; a buyer who finds out at receiving has already lost that option.
Compare the full landed cost
Compare a complete quote rather than applying an economy-wide tariff average to a garment. Classification, origin, applicable trade measures, shipment terms and fees affect the actual import cost; obtain the shipment-specific inputs from the broker or responsible import specialist.
For an illustrative unit-cost comparison, assume a $12 purchase price, $1.80 freight, $1.64 duty supplied for the example, $0.25 insurance and $0.35 handling:
Total modeled unit cost = 12 + 1.80 + 1.64 + 0.25 + 0.35 = $16.04
Gross margin at $24 selling price = (24 − 16.04) / 24 = 33.17%
The $1.64 duty is an assumed input, not a current tariff quote. Accounting determines which actual costs belong in inventory and when they become cost of goods sold. A recorded freight line and per-unit cost allocation are separate capabilities to verify.
Compare alternate suppliers on equivalent specifications, delivery windows, landed cost and approved sourcing criteria. Do not assume a particular country is always the lower-cost option.
What to look for in procurement software for apparel
Bring a size-run order to the demo rather than checking a generic feature list:
Variant identity. Request 2 Small, 4 Medium, 4 Large and 2 XL. Verify that each variant has an unambiguous identifier and stock record. A matrix view is useful, but separate well-mapped SKUs can also represent variants.
Partial receipt. Receive 2 Small, 3 Medium, 4 Large and 2 XL: eleven units arrived and one Medium remains due. The total shortage must not obscure which size is missing.
Supplier proposal. Have the supplier offer a different color for that Medium. Inspect the proposal, acceptance and actual receipt without rewriting the original requested variant.
Channel coverage. Test the supplier’s actual email, marketplace or portal route. Agree how unsupported confirmations are recorded manually and how duplicate ordering is avoided.
Cost review. Keep unit prices, freight and duty evidence available. Confirm where allocation, valuation and later adjustments happen; attaching freight to an order does not prove automatic per-unit capitalization.
Finance handoff. Trace the purchase, partial receipt, invoice and any credit through the agreed system. Finance determines posting and valuation, including unresolved differences.
Where LineNow fits
LineNow connects purchasing, supported supplier communication and receiving context around a living PO. Use the size-run example to verify item mappings, buyer acceptance and outstanding quantities in your setup. Keep assortment planning and the OTB budget in the responsible planning process; verify any connection rather than assuming a budget automatically governs purchasing.
