Forecast, MFP, OTB, buy, allocate, replenish and in-season on a single versioned number — reconciled live, not at month-end.
Why one model changes how the team plans.
Full-price sell-through gap between retail leaders and the industry — most of it down to how the plan stays connected.

What breaks before the connected plan runs to plan.
Planning·Month-end reconciliation · SS27Three steps from five systems to one model that reconciles live.
Tightly · Connected plan live· three stages from data to decisionLiveFive systems collapse into one
Forecast, MFP, OTB, buy, allocate, replenish and in-season stop being five files that meet at month-end. They become seven layers of one versioned model — every layer reads and writes the same number.
Reconcile live, with a verdict
Top-down and bottom-up sit on the same surface. Tightly reconciles the two continuously and returns a verdict — On track, Coverage gap or Over-committed — with the gap it found (committed minus target).
Every role off one number
Finance and merchandising work the same versioned plan through Working → Submitted → Signed-off. Change the forecast and the plan moves; commit a buy and OTB draws down — for everyone, at once.
Change one number. The whole plan moves.
Every capability operates on the same numbers. Change one and it reconciles everywhere — no nightly extracts, no version drift.

“We've tried several inventory tools and Tightly is hands down the best. It has changed how we plan to such an extent that we genuinely can't remember how we coped before.”

How does this integrate with our ERP (NetSuite / Dynamics / SAP) and Shopify?
Tightly reads from your SoR and writes the proposed plan back. Most teams keep their existing ERP for record-keeping and move all planning into Tightly. No rip-and-replace.
What happens to our existing DP tool?
Most customers retire their DP tool inside the first cycle — once Tightly's forecast and plan are running live, the DP tool is a duplicate. You can run them in parallel for confidence.
How long does it take to onboard?
First useful forecast and plan in week one. Live reconciliation by week three. Full retirement of legacy DP/MFP tooling by end of first cycle (4-8 weeks).
Can different brands run on different policies?
Yes — each brand has its own model, policies and team. The group rolls up live (see /platform/scale).
One model. Forecast to markdown, reconciled live.
There's nothing to rip out. Tightly runs on your existing ERP, EDI, e-commerce and POS. Give us 30 minutes and we'll show it on your own categories.
