The plan that runs on top of your ERP.
NetSuite is the system of record for transactions — orders, inventory, GL. It's not a planning tool, and the NetSuite Demand Planning module is well known for being thin where retail planning gets specific. Tightly is a purpose-built planning layer that runs on top of NetSuite (or any ERP) and feeds approved POs straight back.
Keep what works. Lose what breaks.
ERP stays the system of record
Tightly doesn't replace NetSuite. It runs the merchandise plan on top of it, then pushes approved POs back so the ERP stays the single source for transactions.
Retail-specific planning
MFP, OTB, assortment, allocation, replenishment, in-season and markdown — built for the way a retail or DTC merchant actually plans, not the generic demand-planning module.
Live in weeks
Tightly is configurable on day one, so the planning team is using it inside weeks — not after a multi-quarter consulting engagement.
It shows up in the numbers.
