What breaks before assortment planning runs to plan.
Three steps to a range reconciled to the plan.
The range opens from the plan
Every category opens with a financial envelope drawn from the MFP — the $ the range has to hit by channel and month. The range starts tied to the buy.
AI look-alikes fill the range
Tightly's look-alike model matches each style on image and attributes — same category, ±20% price — to find its nearest sellers. Cold-start a new option from them; replace a drop without losing coverage.
Committed depth reconciles to the envelope
Depth per option rolls up to committed $; Tightly compares it to the envelope live and returns the verdict — Coverage Gap, On Track or Over-committed — then stages the buy at 70% of depth.

DROPPEDWhat changes once the range fits the demand.
Range to the option level
Style, colour, size and pack laid out against the financial plan. Option counts, buy depth and width fit the OTB without a separate reconciliation.
Cohorts, not last-year-plus-X
New styles draw from a real visual and attribute cohort — 2–3 actual comparable products — not a parent-category average that hides the spread.
See the holes before sign-off
Tia flags where the range is thin: missing price points, gaps in good-better-best, weak attribute coverage. The catch happens before the first six weeks of sell-through.
One range, every channel
DTC, wholesale and retail draw off one master range with channel-specific buys. No diverged spreadsheets, no missed channel-level cuts.

“We used to carry a bit of everything and mark half of it down. Now the range is edited to the plan before the buy — fewer, deeper styles, and the full-price sell-through to show for it.”

How does the range reconcile to the plan?
Committed depth (Σ planned depth × price across BUY styles) is compared live to the MFP seasonal envelope for the category × channels. Within ±2% it's On Track; under with candidates still to detail is a Coverage Gap; under when fully detailed is unused seasonal room; over is Over-committed. The margin is checked against target at the same time.
How do the AI look-alike recommendations work?
Tightly's proprietary look-alike model reads each style's image and its attributes and finds the most similar sellers — filtered to the same category and ±20% price, then ranked by match. Use them to cold-start a new option, replace a dropped one, or fill a coverage gap without losing range coverage.
How is a new style planned with no sales history?
It's seeded from its nearest look-alikes — the closest-matching styles that do have history — so depth and size curve start from what actually sells, not a flat last-year run rate.
Can we plan a different size curve per channel?
Yes. DTC, wholesale, retail and marketplace each get their own size curve and channel split; the forecast feeds size depth per channel and the range adjusts independently per surface.
When does depth become a buy?
Setting depth moves an option from Candidate to BUY; the buy stages at 70% of planned depth as draft POs the buyer reviews. Drop an option and it leaves the committed total — the reconciliation updates live.
