🛒 What Is Open-to-Buy (OTB)?
Open-to-Buy (OTB) is a forward-looking budgeting method that helps retail and ecommerce businesses determine how much inventory to purchase over a future period—typically monthly or quarterly.
In essence, it answers the question:
“How much inventory can I buy this month while staying aligned with my sales plan and cash flow goals?”
Rather than simply reacting to what’s selling, OTB equips you with a proactive plan that aligns purchasing with your financial strategy.
