Assortment Planning for Wholesale Apparel Brands

Wholesale apparel planning introduces account-specific complexity that DTC planning frameworks don't address. This guide covers how wholesale brands plan assortments across accounts, floor sets, and line sheets — and where the process breaks down in spreadsheets.

Assortment planning in the wholesale context

Assortment planning for wholesale apparel brands is the process of defining the brand's seasonal product offering and then determining how that offering is structured, sized, and committed across wholesale accounts — each of which may have different minimums, floor set schedules, and channel requirements.

Wholesale planning operates at two levels simultaneously:

The brand assortment: the full set of styles the brand is developing and making available for wholesale
The account-level selection: which subset of the brand assortment each wholesale account will carry, at what depth, and on what delivery timeline

A wholesale planning team must manage both levels — and keep them connected. A brand assortment that's finalized without account-level input may include styles that don't meet any account's minimum order requirements. Account selections that aren't reconciled against the brand's OTB may commit more units than can be produced.

Account-level complexity in wholesale assortment planning

Minimum order quantities

Most wholesale accounts have minimum order requirements — by style, by color, or by total units per delivery. These minimums exist because vendors need minimum runs to justify production and minimize per-unit cost.

The planning implication: a style that meets the brand's assortment criteria may not be able to meet a specific account's minimum requirement from that account's allocation alone. The planner must either:

Find enough demand across multiple accounts to meet the vendor minimum
Combine the account's allocation with DTC inventory to meet the minimum
Remove the style from that account's selection

This decision must be made before the buy is locked — not after the PO is submitted.

In spreadsheet-based wholesale planning, minimum order quantity conflicts are often discovered only when POs are being submitted — after the assortment decisions have been communicated to accounts. Identifying these conflicts during assortment planning avoids account relationship issues.

Floor set windows and delivery timelines

Wholesale accounts plan their floor sets — the seasonal refresh of their selling floor or website — months in advance. They require vendors to deliver inventory within specific windows tied to these floor sets.

This creates a scheduling constraint that the wholesale assortment plan must account for. Styles that can't be delivered within a specific account's floor set window either need a production timeline adjustment or need to be moved to a different delivery or excluded from that account.

Managing floor set windows in a spreadsheet requires a separate calendar layer that must be manually reconciled against the assortment plan. When the assortment changes — a style is dropped, a delivery window shifts — the floor set tracking needs to be updated independently.

Channel exclusivity and account restrictions

Many wholesale brands offer channel exclusives — styles or colorways restricted to specific accounts or channels. The assortment plan must reflect these restrictions:

Which styles are restricted to specific accounts?
Which colorways are DTC-exclusive vs wholesale?
Which accounts have exclusivity on specific styles for a period?

Channel exclusivity decisions affect the assortment plan, the OTB allocation, and the line sheet — in a disconnected planning environment, keeping these consistent across multiple files is error-prone.

Building the wholesale line sheet from the assortment plan

The wholesale line sheet — the document shown to buyers at account-level buy reviews — is a downstream artifact of the assortment plan. It shows the account which styles are available, at what prices, with what delivery windows.

The problem in spreadsheet-based wholesale planning: the line sheet is typically maintained as a separate document from the internal assortment plan. When the assortment changes — a style is dropped, a price is adjusted — the line sheet must be manually updated.

If the line sheet shown to accounts is not synchronized with the internal assortment plan, account commitments are made against inaccurate data — creating conflicts that require resolution during or after the buy review.

In a connected planning system, the assortment plan is the source of truth for what's available to accounts. Changes to the assortment automatically flow through to the account-facing view — there is no separate line sheet document to maintain.

OTB for wholesale brands

Tracking OTB by account and total

Wholesale OTB must account for commitments at two levels:

Account level: What has each account committed to buy?
Total brand level: Do total account commitments across all accounts stay within the OTB?

In spreadsheet-based wholesale planning, account commitments are tracked in one file (often a separate tracker per account or buy period) and total OTB in another. Reconciling them — making sure total commitments don't exceed the OTB — is a manual step that happens at the end of the process, often after commitments have been made.

Wholesale vs DTC OTB buckets

Brands that sell both wholesale and DTC should track OTB as separate channel buckets, not a single pool. A style sold at 200 units wholesale and 300 units DTC has different production economics, inventory requirements, and margin profiles than the same style sold 500 units DTC.

Combining wholesale and DTC OTB into a single bucket means that wholesale over-commitment can silently consume DTC buying budget — or vice versa — without a deliberate trade-off decision.

The wholesale assortment planning calendar

Wholesale planning operates on a longer lead time than DTC because account buy reviews, production minimums, and delivery window alignment add scheduling complexity:

| Stage | Typical timing | |---|---| | Line development begins | 6–8 months before season start | | Brand assortment finalized | 5 months before season start | | Account buy reviews | 4–5 months before season start | | Account commitment collection | 3–4 months before season start | | OTB reconciliation | 3 months before season start | | POs submitted | 2.5–3 months before season start |

The account buy review stage — where account buyers select styles and commit quantities — is the most operationally intensive. Multiple accounts buying simultaneously, each with their own minimum requirements and delivery preferences, must be managed against a single brand OTB and production capacity.

Common wholesale assortment planning failures

Over-commitment to accounts: Total account commitments exceed the brand's OTB or production capacity. Discovered too late to reduce commitments without account relationship issues.

Minimum order quantity failures: Styles are assigned to accounts that don't generate enough volume to meet vendor minimums. The style must either be consolidated across accounts or dropped from specific selections.

Line sheet inconsistency: The version of the line sheet shown to Account A includes a style that was dropped from the assortment after the Account B review. Account conflicts follow.

Floor set timing misalignment: A style is committed to an account for a delivery window that doesn't align with the brand's production timeline. Discovered after the commitment is made.
