Planning inventory effectively is a cornerstone of success for eCommerce businesses, and one of the most powerful tools for achieving this is Open to Buy (OTB). While traditionally used by brick-and-mortar retailers, OTB has become invaluable for online stores aiming to maintain balanced stock levels, minimize holding costs, and maximize cash flow.

Let’s explore how to create an effective Open to Buy plan tailored to your online store’s unique needs, from understanding the basics to calculating OTB with precision.

What is Open to Buy for Retailers and eCommerce Merchants?

Open to Buy (OTB) is an inventory planning and purchasing strategy that allows retailers to control their inventory budget by forecasting what, when, and how much to buy. Traditionally used by physical stores, OTB has gained relevance in eCommerce for maintaining balanced inventory levels and optimizing purchasing schedules.

For eCommerce merchants, OTB is essential in aligning purchasing decisions with fluctuating consumer demand, reducing the risk of both overstocking and stockouts.

By implementing an OTB approach, merchants can better manage the financial impact of unsold inventory, especially during unpredictable periods like holiday seasons.

Why is Open to Buy Important?

Open to Buy is a strategic tool that helps eCommerce businesses in several ways:

Improves Cash Flow Management:

By setting clear budgets for purchases, OTB helps in managing cash flow more effectively. This is especially beneficial for smaller or seasonal businesses where liquidity is essential for scaling.

Reduces Overstock and Holding Costs:

Overstocked items tie up capital and incur holding costs, which can erode profit margins. OTB helps maintain a balanced inventory level to meet demand without overstocking.

Enhances Forecasting and Demand Planning:

OTB requires regular assessments of future sales trends. This forward-looking approach ensures that merchants have enough stock to meet demand, especially during peak times.

For example, an eCommerce store specializing in seasonal apparel might plan its OTB differently throughout the year, adjusting for high-demand periods such as summer and winter, and scaling back in off-peak months.

OTB Software for Shopify and Other Platforms:

Platforms such as Shopify benefit significantly from OTB software. Merchants can leverage inventory planning apps to track sales trends, manage stock, and set purchasing limits.

Open to Buy Formula

Understanding the OTB formula is essential for accurate planning. The basic formula is:

Open to Buy=Planned Sales+Planned End Inventory−Current Inventory\text{Open to Buy} = \text{Planned Sales} + \text{Planned End Inventory} - \text{Current Inventory}

Open to Buy=Planned Sales+Planned End Inventory−Current Inventory

For instance, if an online footwear store expects $10,000 in sales for the month, aims to end with $5,000 in inventory, and currently has $2,000 in stock, its OTB calculation would be:

10,000+5,000−2,000=13,00010,000 + 5,000 - 2,000 = 13,000

10,000+5,000−2,000=13,000

This calculation shows that the store should budget $13,000 for purchases to meet its sales targets without overstocking.
