The receipt budget, reconciled live.
OTB is the seam between the MFP, the line plan and evergreen replen. Tightly holds those three on one model, so the receipt budget flexes with the MFP and gates every commit before it breaches.

Cells projected to overshoot surface on the trading view before the buy goes through, with the dollar impact called out by category.
Reserve & free envelope tracked
In-season reserve held at policy (typically 40%). Free envelope, committed and reserve all tracked separately.

“One of the most exciting propositions we've ever brought into the business. There is so much power under the hood that we honestly can't picture running the category without it now.”
Working capital freed
The OTB you run today, and the one Tightly delivers.
OTB lives in a spreadsheet, rebuilt once a month from the ERP. You commit buys against last month’s number — by the time the overspend shows, the PO is already placed.
OTB draws down live as buys commit. Overspend is flagged before the PO, and the 40% reserve is held by policy — no month-end surprises.
Open-to-buy is one part of the connected plan.
Financial planning
MFP and OTB share one model. A plan change moves the envelope live.
Allocation
Buy proposals stage against OTB — never propose a commit you can't fund.
Demand forecasting
OTB sized against forecast demand, not last year's receipts.
Does OTB tie back to the MFP live?
Yes. The MFP is the envelope; a revision to planned sales, markdowns or EOP inventory flows straight through to the OTB the line plan and evergreen replen consume — no re-keying, no drift.
How do you stop the line-plan build breaching the envelope?
As buyers commit style depth into the line plan, running consumption is shown per month × class × channel. A commit that would push a month over the envelope is blocked at Submit with the dollar impact called out.
Does evergreen replen consume the same OTB?
Yes. Continuity reorders draw the same receipt budget as seasonal, and both are visible on one view — so seasonal buyers see how much replen has already consumed before they commit.
How does the reserve policy work?
Configurable per class. Most teams hold 40% of envelope as in-season reserve, freed in tranches by sell-through trigger. Reserve is a hard gate, not a guideline — overrides need sign-off.
Does Tightly write back to our ERP?
Yes. Approved buys stage to the ERP as POs once the buyer hits Submit. OTB drawdown happens live in Tightly; the ERP becomes the system of record at commit.
Spend control, live. Every buy reconciled against the plan.
