What is wholesale open to buy for retailer networks?
Wholesale open to buy is the remaining amount a retailer (or distributor) is still allowed to purchase from a brand for a defined period, usually a season or delivery window.[1][2] In a brand’s retailer network, open-to-buy (OTB) is the shared budget or unit capacity left after earlier orders, not a vague “how much they might want.”
For brands selling B2B, OTB is less about the retailer’s internal spreadsheet and more about the rules you publish: how much each account can still book, in which window, against which catalogue. Done well, partners plan buys against clear remaining capacity instead of chasing sales reps for line sheets and verbal limits.

How does open to buy differ from assortment planning and demand forecasting?
Open to buy is remaining purchase capacity for a period; assortment planning chooses which products belong in the range, and demand forecasting estimates how much will sell. Mixing the three creates noisy briefs and broken caps.
- Assortment answers “what may we offer this account or channel?” Depth, exclusives, and drop structure live here—see wholesale assortment planning.
- Forecasting answers “what do we expect to sell or ship?” It informs production and allocation—covered in wholesale demand forecasting.
- OTB answers “how much buy capacity remains in this window?” It constrains orders after assortment and forecast choices are set.
Retailers still run their own OTB from planned sales, inventory, markdowns, and receipts.[1][3] Your job as the brand is not to replace that math. It is to expose season-visible catalogues, order caps, and remaining capacity so their OTB can land cleanly on your B2B storefront.
How do brands set seasonal OTB caps and season windows?
Season windows are fixed order-and-delivery periods (for example pre-book versus in-season replenishment) with start and cut-off dates; order caps are the maximum value or units an account may still place inside that window. Caps can sit at account, territory, category, or SKU level.
A practical wholesale OTB process usually looks like this:
- Define seasons and delivery windows on the calendar (pre-book, drop one, drop two, continuity).
- Agree framework volumes or budgets with key accounts—often inside a wholesale framework agreement.
- Translate agreements into caps (currency, units, or both) and publish them before the window opens.
- Split pre-book vs replenishment so early commitment capacity is not eaten by late opportunistic orders.
- Reserve buffer for top doors and proven sellers rather than releasing every unit on day one.
Fashion, beauty, and home brands often align windows with trade-show and delivery norms; food and continuity lines may use rolling monthly caps instead of hard fashion seasons. Either way, the window and the cap must be visible before the buyer builds the basket.

What should retailers see in a B2B portal to manage open to buy?
Retailers should see season-tagged catalogues, remaining buy capacity, cut-off dates, and live order rules in the same portal where they place the PO. Hiding caps in email threads defeats retailer open to buy planning.
A useful distributor portal / B2B storefront surfaces:
- Season and window labels on the catalogue and on each line (pre-book vs replenishment).
- Remaining OTB for the account—value and/or units—updated as orders confirm.
- Cut-off and delivery dates so buyers do not build dead baskets after the window closes.
- MOQ, pack size, and case rules next to price, not in a separate PDF.
- Credit status at a glance, without revealing internal risk notes.
- Order history and reorders for continuity SKUs so sell-through-informed top-ups are fast.
That is the core of many distributor portal advantages: self-serve rules instead of spreadsheet chases. Brandgate is one way to run that branded portal layer—season-visible catalogues, remaining capacity, and order rules in one place for Nordic and EU wholesale networks. Book a demo if you want to see the flow with your own account structure.
Line sheets still matter for storytelling and launches; they should match the portal catalogue, not contradict it. When the wholesale line sheet and the live season view drift apart, OTB discipline collapses.
How do order caps, MOQs, and credit limits work together?
Order caps limit how much of a season or category an account may still buy; MOQs set the smallest acceptable order or line; credit limits cap exposure on unpaid invoices. At checkout they should apply in a transparent stack, not as surprise blocks.
A clean stack looks like this:
| Control | What it protects | Typical buyer view |
|---|---|---|
| Season / SKU cap | Allocation and oversell risk | “Remaining buy on AW pre-book” |
| MOQ / pack rules | Handling cost and ship efficiency | “Minimum 6 units / 1 case” |
| Credit limit | Cash and receivables risk | “Available credit before this order” |
If credit is exhausted, OTB remaining is irrelevant until finance clears the account—tie this to your wholesale credit control process. If MOQs are set without regard to small doors’ OTB, partners either break packs or abandon the order; setting better wholesale MOQs keeps caps and minimums aligned.

What data do brands need to support partner OTB without overselling?
Brands need reliable open orders, confirmed receipts, available-to-sell by window, and simple sell-through signals from priority doors—not a perfect forecast. Overselling happens when caps ignore what is already committed.
Minimum data set:
- Open orders and confirmations by account and season window.
- Available inventory (or ATP) tagged to the windows you sell into.
- Account caps and framework commitments in one master, not side notes.
- Fill rate on recent orders so you see where caps or stock failed partners—see wholesale order fill rate.
- Sell-through or intake feedback from key retailers where you can get it, to guide mid-season releases—see wholesale sell through.
You do not need every door’s full retail OTB model. You need enough truth on commitments and stock that a cap in the portal means the same thing in the warehouse.
How should brands handle mid-season OTB changes and reorders?
Mid-season OTB changes should be published as revised caps and window notes, with reorder paths that favour proven sellers over silent one-off spikes. Quiet spreadsheet edits freeze partners who planned in good faith.
Practical patterns:
- Release reserved buffer to accounts with strong intake or sell-through, not only to the loudest inbox.
- Keep replenishment SKUs easy to repeat so continuity does not require a new negotiation—making wholesale reordering easier supports that.
- Separate promotional bursts from base OTB so a short campaign does not silently burn season capacity.
- Communicate cut-over dates when a pre-book window closes and replenishment rules take over.
When stock is short, partial confirmations and clear backorder rules beat silent cuts. Partners can adjust their own open to buy only if they see what actually shipped.
What mistakes break wholesale open-to-buy programmes?
Programmes break when caps live only in salespeople’s heads, seasons are vague, and portal catalogues disagree with the deals on paper. The failure mode is familiar: oversell on heroes, underserve loyal doors, and endless exception emails.
Watch for these traps:
- Treating OTB as assortment — blocking SKUs that were already promised in the range.
- Treating OTB as a forecast — changing caps daily without telling buyers why.
- One global cap for every door — ignoring framework tiers and territory reality.
- MOQs that exceed remaining OTB for smaller accounts.
- Credit holds discovered at pick/pack instead of at basket time.
- No distinction between pre-book and replenishment — late orders cannibalise committed production.
- PDF line sheets forever — no remaining-capacity view, no season filter, no self-serve truth.
Wholesale order caps and B2B season windows only work when the retailer network can see them while ordering. If your process still depends on forwarding spreadsheets, the portal is incomplete—not the buyers.
Closing note
Seasonal open to buy is a commercial contract made operational: windows, caps, and visibility. Give partners a branded place to see remaining distributor buying budget, season catalogues, and stacked rules, and you spend less time policing orders and more time allocating scarce product to the doors that earn it. When you are ready to replace spreadsheet chases with that flow, book a demo or see pricing.
