Open-to-buy (OTB) planning gives a fashion brand a disciplined answer to a practical question: how much more inventory can the business commit to buying during a defined period, after accounting for expected sales, stock already held, planned ending inventory and orders already placed? For a UAE brand selling through more than one channel, a useful OTB plan can connect buying decisions to real stock and cash commitments instead of treating each new order as a standalone opportunity.
OTB is a planning framework, not a sales forecast, a guarantee of demand or an approval to spend. It is most useful when the inputs are explicit, the valuation basis is consistent and someone updates the plan as actual sales and inbound orders change.

What open-to-buy measures—and what it does not
An OTB budget estimates the merchandise a retailer can still buy for a period while staying within planned sales and inventory targets. Retail teams often work with a retail-value budget for category control, a cost-value view for purchase commitments, or a unit view for replenishment. Each view answers a slightly different question. The essential discipline is to choose the basis first and avoid adding retail-value inventory to cost-value purchase orders in the same calculation.
OTB does not tell a buyer which styles customers will prefer. It cannot repair inaccurate stock records, unrealistic lead times or a forecast built without channel history. Nor is it identical to cash available in a bank account: a merchandise budget is one control in a wider cash plan that also includes operating costs, supplier payment terms and timing.
Choose the period and level of detail
Set a planning period that matches the decisions the business actually makes. A monthly view can help with stable replenishment and cash planning; a shorter review may be useful when orders, launches or demand shifts need a faster response. The right cadence depends on supplier lead times, the brand’s trading pattern and how quickly reliable sales data becomes available.
Decide whether the plan is organized by category, channel, collection, store or a combination. Start at a level that the team can maintain. A plan broken down into hundreds of tiny cells can create false precision if the business has no dependable data at that level. At the other extreme, one budget for all apparel may conceal that one category is absorbing funds while another is close to a stockout.
For UAE operations, agree whether the plan is for the whole business, a specific emirate, a channel or a location. If online and physical sales share stock, reflect that pool rather than assigning the same units to both. If different entities or importers hold inventory, preserve those distinctions in the reporting so commercial plans reconcile to the operational records.
Build the inputs before calculating
A workable plan needs a clear opening stock position, a sales forecast, any planned markdown assumptions, a target ending inventory and a list of outstanding purchase orders or confirmed inbound commitments. Record how each figure is valued and where it came from. The forecast can draw on historical sales, known launches, confirmed retail activity and channel-specific plans, but assumptions should be visible rather than hidden in a single total.
Treat orders as commitments even when goods have not arrived. Reconcile purchase orders for quantities, costs, expected arrival windows, cancellations, deposits and balance-payment dates. Where a supplier has confirmed an order but the system has not yet recorded it, the budget may overstate what is still available to buy. A weekly or monthly reconciliation between buying, finance and operations can catch that mismatch.
Separate returns and transfers from fresh demand. A return may bring a unit back into sellable stock, but its condition, timing and location can affect whether it is actually available for the next customer. Transfers between locations change where stock can sell; they do not necessarily increase the business’s total inventory. Keep these movements distinct in the source data.
Use one formula and keep the basis consistent
A commonly used retail-value OTB formula is: planned sales + planned markdowns + planned ending inventory − planned beginning inventory. The result estimates planned purchases at retail value for the period. To derive a remaining buying budget, compare the plan with open purchase orders already committed for that same period and on the same valuation basis. Retailers may also build a cost or unit version, but should not mix units, retail prices and supplier costs in one calculation.
The formula is a starting point, not a promise that the period will end exactly as planned. Maintain a version of the forecast and replace projections with actual sales and inventory at each review. When assumptions change, update the remaining plan forward rather than rewriting history. This makes variances useful: a manager can see whether a shift came from demand, delayed receipts, markdowns or an initial forecast error.
Add a UAE cash-and-import view separately
A UAE-facing buying plan should show the expected landed and cash-flow commitments alongside the merchandise budget. Supplier cost, freight, insurance, customs-related charges, payment terms and the timing of inbound goods can all affect the commercial decision. Do not assume that a retail-value OTB number is the same as cash required to land new stock.
Import VAT needs particular care. Federal Tax Authority guidance describes the importer, customs details and VAT-registration conditions that affect how import VAT is accounted for; recovery may depend on eligibility under the applicable rules. For planning, keep the relevant tax cash-flow line visible and have finance or a qualified tax adviser confirm the treatment for the actual importer and transaction. This article is general operational guidance, not tax advice.
Similarly, do not apply one customs assumption to every shipment without checking the product classification, route and importer responsibilities. A plan can use provisional estimates, but label them as estimates and set a review point before purchase orders are approved. This protects the budget from treating uncertain landed costs as settled facts.
Allocate the budget across channels deliberately
A shared OTB plan should make the channel logic visible. Decide how much stock is intended for wholesale, retail locations, direct e-commerce or marketplace partners only if those channels are genuinely part of the operating model. Identify which units are reserved, which can be reallocated and who can approve a transfer or reorder.
Avoid counting the same future stock twice—for example, once as a confirmed inbound order and again as available buying capacity. When one channel sells faster than expected, compare the value of transferring stock with the cost and timing of placing a fresh order. A simple scenario can show the trade-off between protecting a fast-moving item and preserving budget for upcoming launches.
Keep product-level reorder triggers separate from category-level OTB control. Core products with predictable replenishment may need minimum stock or reorder logic; OTB can still act as a category-level spending boundary. For short-run or trend-sensitive items, the team may choose to reserve more of the budget until early selling signals arrive. The plan should clarify those choices rather than forcing every product into the same buying rule.
Review the plan as a control cycle
At each review, compare actual sales, stock and receipts with the prior plan. Ask what changed, whether the change is temporary or persistent, and which later purchase decisions need to move. Update open orders for delays, partial deliveries and cancellations, then recalculate the remaining budget. A concise variance note is more valuable than simply replacing the old number.
Set escalation rules before a variance becomes urgent: who can approve spending above plan, when a slow-selling category should pause new commitments, and what evidence is required to increase a budget. The thresholds should fit the business’s governance and cash position. OTB can support these decisions, but management remains responsible for priorities and trade-offs.
Open-to-buy checklist
Choose the period, channel and category level the business can maintain reliably.
Select one valuation basis for each view: retail value, cost or units.
Reconcile opening stock and all open purchase orders before calculating remaining budget.
Record forecast sales, markdown assumptions and target ending inventory with their sources.
Separate merchandise OTB from landed cost, supplier payment timing and tax cash-flow assumptions.
Keep shared inventory allocations visible across stores, wholesale and e-commerce.
Set named owners, approval thresholds and a review cadence.
Replace projections with actuals after each period and log the reasons for material variances.
Turn the plan into better commercial conversations
A well-maintained OTB view creates a shared starting point for buyers, finance and commercial partners: what the brand expects to sell, what it has already committed to buy, and where the remaining capacity sits. It cannot decide which market, retailer or assortment is right, but it can make those conversations more concrete by showing the financial and inventory consequences of each option.
