WHAT IS OTB IN RETAIL
OPEN TO BUY DEFINITION
OTB stands for Open-to-Buy. It is the amount you need to buy products with, in order to achieve the set sales budget for a certain period, usually 6 months. It is calculated at cost and assigned to different product categories based on each category’s contribution to total sales.

OTB calculation is one of the most important tasks to master when starting a retail business. Failing to calculate the open to buy budget can be detrimental for the business, due to stock problems that will soon arise from improper planning.
Calculating Open to Buy is an essential step in the product sourcing process for the next season and is directly linked to the same period’s sales budget. Whether you are running a multi-brand store or your own private label business, you will probably need to know how to calculate your OTB
WHEN DOES THE OPEN TO BUY BUDGETING HAPPEN?
The OTB budgeting comes after the sales budgeting step in the buying process and is followed by the actual ordering step.
You cannot set an OTB budget if you don’t have a sales budget for the period you are planning for.

WHAT IS THE OUTCOME OF THE OPEN TO BUY PROCESS?
If you perform the OTB calculation process properly, you will get the dollar amount for purchases for the next period (e.g. 6 months), segregated into product departments and indicating the intake and realized margins for each department and the entire business.
Based on that amount, you can start placing your orders from your suppliers and plan them to arrive at different intervals during that period (6 months).
OPEN TO BUY FORMULA
Opening Stocks + Intakes (Purchases) - Sales = Closing Stocks
This OTB formula accounts for markdowns by calculating sales at cost (COGS).
Opening Stocks, intakes and closing stocks are also calculated at cost value, not retail value.
For example, if the business is targeting 2 turns per year, then the closing stock should provide a 6 months cover. If the targeted turnover is 3 times per year, then the stock cover should be 4 months, .. and so on.
* Our excel template displays the forward stock cover separately for each month, so the planner can increase/decrease their purchasing amount accordingly. This also helps during the year while updating the sheet with actual sales data as the months roll in, to show the current stock cover and take corrective actions if needed.
OPEN TO BUY TOOLS
RETAIL BUYING PLAN EXCEL TEMPLATE
This is the retail buying plan excel template for multi-department calculation of an open to buy budget.
It includes monthly sales and intakes, and is expandable to include more departments/ categories/ classes. The sheet also automatically calculates the forward stock cover for each category, every month, so you can increase/decrease your purchases based on the stock cover you want to target for each category.
You can use this excel sheet to create a 6 month merchandise plan, 6 months in advance. The total months on the sheet are 18 months, and we show you exactly how to fill it in the PDF attached to it.
You can get this template as a premium plus member, and we provide separate demo sales, margin & inventory data for you to practice using it.
OPEN TO BUY EXCEL
TERMINOLOGY OF THE OPEN TO BUY TEMPLATE
Opening Stock: The amount of stock (at cost) you have at the beginning of the period.
Forecasted/Actual Intake: The stocks you are receiving, whether already ordered or still to be ordered.
Forecasted/Actual Sales: Actual or budgeted sales for that month/period
Closing Stocks: Stocks (at cost) at the end of the period
Forward Cover: How many months your current stock on hand will cover your sales.
Intake Margin: The margin of the products if sold at full price (without markdowns)
Realized Margin: The margin at the end of the season/period after applying markdowns to your products.
ONLINE OPEN TO BUY CALCULATION TOOL
The second option to calculate your retail buying budget is our online Open to Buy calculation tool, which is a quicker, easy to use, step-by-step tool for retail & ecommerce store owners to calculate their buying budget by department/category or class.
The OTB tool supports up to 6 product segments (departments/categories/classes) in one process and can be used multiple times for more segments. It operates on a period basis (not monthly), so you can choose this period to be 4 months, 5 months, 6 months,..etc, based on your entered data.
It will take you through the process step-by-step and give you at the end the buying budget segmented by the segments you entered at the beginning (e.g if you want department level, enter department sales.. if you want category level enter category sales… and so on). You then use these amounts to start placing your orders.
The open to buy online tool is part of our membership plans, and premium plus members get access to both, the OTB tool and the OTB excel, as well as the practice exercise with demo data, to master the entire process using both tools.
In the next chapter we will explain all the data that you will need to generate, in order to use it in the OTB budgeting process and where to extract this data from.
In this chapter we will list the exact steps to create a retail buying plan

STEPS OF OPEN TO BUY BUDGETING
Here we will explain the steps of creating a retail buying plan for a 6 months period, and we will use an example of July 2020 to December 2020. This means we want to plan for the orders that we will place in order to arrive in the period from July 20 to Dec 20.
STEP 1 : SET YOUR SALES BUDGET
For Budgeted Period
You start by setting the sales budget for your retail stores for the period you want to plan the buying for, here July 2020 to Dec 2020.
If you don’t have a sales budget in place, you will need to create a forecast and you can take last year’s sales for the same period as a guidance and build on it.
For Cover Period
You then create a sales forecast (budget) for the period you intend to cover (e.g 6 months). The covered period is the period that immediately follows the period you are buying for.
This is important because at the end of Dec 2020, you don’t want to have the stores empty. You need to always have a forward cover in place as a safety net.
If you plan to have a forward stock cover of 6 months (i.e turn your inventory 2 times per year), then this will be 6 months forecast for the period following the budgeted period. In our example this would be Jan 2021 to June 2021.
Again, here you can take sales from last year as guidance for your forecast.
If you want to turn your inventory 2 times per year, your cover will be 6 months. If you target 3 turns, your cover will be 4 months,…etc.
We keep an updated list with inventory turnover benchmarks for different retail segments here, which you can use as a guide for your business.
STEP 2 : DEFINE YOUR MARGINS
Define your realized margin for the sales you budgeted and forecasted in the previous steps. This should take into considerations any markdowns you will carry during these periods.
STEP 3 : GET YOUR OPENING STOCK AT COST
Your opening stock is the stock value (at cost) that you carry at the beginning of the period you are budgeting for. For our example here this would be at the beginning of July 2020.
If you were budgeting for a period that starts tomorrow, this would have been your current stock value (at cost). However; since we always budget for a period well in advance (usually 6 months ahead) this would mean calculating your opening stock well in advance.
We will explain this quickly with an example
You are now in Jan 2020 and want to budget for July 2020 to Dec 2020. You will need to get the opening stock for July 2020.
This will require you to extract the current stock on hand that you have (at Jan 2020) and then subtract from it any stocks that you will sell from Jan to June 2020 and add to it any stock that will arrive between Jan to June 2020.
Current stock level (Jan 2020) at cost = 100,000$
Sales from Jan to June are 200,000$ at 60% margin
COGS from Jan to June = 200,000 $ x (1-0.6) = 200,000 x 0.4 = 80,000 $
Receiving (orders) that will arrive in March 2020 at cost = 20,000 $
Opening stock at July 2020 = 100,000 $ – 80,000 $ + 20,000 $ = 40,000 $
STEP 4 : CALCULATE THE BUYING BUDGET
Once you have defined your sales, margins and opening stocks in the previous steps, you will plug those numbers in the Open to Buy excel sheet or the online OTB calculation tool to calculate your total buying budget.
You will then use this budget to start placing your orders that should arrive during the budgeted period (e.g between July 20 to Dec 20). If you already have placed any orders that should arrive during this period, you will simply take this out of the budget that you have and order with the remaining amount.
The stock cover that you have defined above (covered period) means that, at the end of the budgeted period (say Dec 2020) you will have enough stock to trade until the end of the covered period (e.g until end of June 2021), even if you haven’t received any more orders after Dec 2020. This is supposed to be a safety net for your business to always have forward cover.
In this chapter we will discuss considerations linked to Open to Buy budgeting.
We will be covering in details :
- Time Considerations
- Critical Issues
- OTB Accuracy
OPEN TO BUY COSIDERATIONS
WHY 6 MONTHS OPEN TO BUY PLAN?
The reason for choosing 6 months as a default period for a retail buying plan is because usually collections are segregated into Spring/Summer and Autumn/Winter and manufacturers usually require orders to be placed 6 months in advance, so that products will be available at your stores at the right time to launch the season. That’s why it is better to have a rolling 6 months budget ready at all time.
Also when you have your OTB for a 6 months period ready, you can place your orders based on their order lead time, not necessarily 6 months in advance.
For example, you can have a distributor that ships your products once you order them, and they arrive within a week or two. In this case, you will utilize the already planned budget for that category and order 2 weeks before you need the products in your stores.
Also having a 6 months rolling buying budget ready all the time means you only have to do this exercise twice a year.
However; we do recommend revisiting your Open to Buy plan regularly and updating it with actual sales as the months start rolling, so you can rectify if you are not meeting your sales budget or if you are making much more sales than planned.
For example: If you are far behind your sales budget and still have some orders not placed you will be able to reduce those orders based on the current sales trend and avoid an overstock situation later on.
If you do not start rectifying the problem within the season, by clearing the extra stocks regularly or adjusting your buying, your OTB for the following 6 months will be automatically lower because your closing stocks will be high.
This means less Open to Buy budget to buy fresh stocks for the coming season and this will affect your sales.
DOES THE 6 MONTHS PERIOD START TOMORROW?
No, it doesn’t.
When we say we will plan for 6 months, we don’t mean starting from next month. Your next month’s buying budget should have already been set 5 months back.
If we are in January now, we should already have our buying budget planned until June.
Now, we start planning for the 6 months from July to December. So by the time you finish your OTB plan, you will have your buying set for actually the whole next year.
This is because for some products you will need enough time in advance to order them, esp. if you are dealing directly with manufacturers.
WHY IS OPEN TO BUY SO CRITICAL IN RETAIL?
Having the wrong retail buying budget means your business could be:
- Overstocked: you will end up with very high inventory at the end of the season
- Understocked: you will not have enough inventory to achieve your sales budget
WHY IS BEING OVERSTOCKED A BAD THING?
When you have too much stocks you will not have sufficient cash flow to order new products for the coming seasons, as your cash is tied to the existing stocks, hence your turnover will become slower.

Being overstocked will also result in clearing your stocks through frequent markdowns, which can harm your brand image, besides reducing your margins.
It costs to actually hold stocks, so if you are overstocked you will be paying unnecessary costs for warehousing and handling your products.
This is why if you sell on Amazon FBA they will ask you to take back your stocks that have not been sold or they will write it off. You will be baring the cost of that too.
Amazon FBA sellers usually want to reduce their inventory storage fees, long-term storage fees and removal fees to improve their profitability. This is done by calculating a right buying budget that is connected to their forecasted sales.

You might be in a situation where you are not able to pay your expenses because you are selling at very low margins. This will affect your P&L and will also reflect on your balance sheet, as explained before.

Many retail businesses fail because of poor inventory planning
WHY IS BEING UNDERSTOCKED A PROBLEM?
You will miss your sales budget if you don’t have enough stocks to sell. You will start selling out of your best selling items first, but this will exacerbate the problem because it is those items that drive the traffic to your stores in the first place, so you will end up losing even more sales.
Besides missing your sales targets due to out-of stock situations in many of your SKUs, there is another problem with being understocked. When customers come and find you don’t have the products available and they start facing this issue frequently, they will slowly start shifting to your competitors.
At the end of the day, customers want their needs met. They don’t really bother who will meet their needs. It is your job to attract them to you and serve them, so you can get their repeated business.
This particular problem of losing marketshare to competition can be very costly to fix. You will have to spend more on customer acquisitions to win back customers that you already had them in the first place, instead of winning even more customers and growing your business.
DO I HAVE TO BE 100% ACCURATE?
Because your stock situation is dependent on your sales performance overall and also the performance of different departments within your stores, it is hard to be 100% accurate on your planning. Usually 5% deviation (up or down) is considered a good result in retail OTB planning.
As we’ve said, it is a very critical process, but also it can easily be mastered if practiced thoroughly and properly.
This is also why we stress again on the fact that OTB planning is an ongoing process. You are advised to keep revisiting and updating your plan with actual sales figures as the months roll in, so you can take any action needed before it is too late.
It should also be noted that having a proper OTB budget is closely tied with having a proper sales budget. If your sales forecasting /budgeting turned out to be completely off, then automatically your OTB plan will also be far from reality. That’s because components of the OTB are purchases and sales.
