Operations & Inventory — logistics and warehouse terms
The ad account and Meta Ads only buy primary demand on the market — but turning that demand into real commercial sales and into cash is something only operational soundness (inventory management, warehouse logistics and delivery service) can deliver.
The terms gathered in this category name exactly those critical points where a sale already won by marketing stays unfulfilled because of operational chaos, or where the company's free cash freezes for months, unmoving, in the form of wrongly purchased goods. These are the heavy costs and financial losses that Facebook's ad account, while counting its virtual ROAS, will never see.

Short operational terms
Stockout — the complete sell-out of your most in-demand, high-margin product position in the warehouse at exactly the moment when market demand for it is peaking (and often, when the marketing team has an active ad budget running on it). This is a double financial loss for the business: lost direct profit and the pointless burn of ad budget, because once the product is gone Meta's algorithm is forced to pause the campaigns and later re-learn them completely from scratch (Optimization Reset).
Reorder Point — the minimum, critical inventory balance in the warehouse at which, the moment it is reached, the operator must immediately place a new batch order with the supplier — before the goods physically run out, accounting for the transport time. The operational formula is strict: ROP = (average daily sales × Lead Time in days) + Safety Stock. The founder's approach of "I look at the warehouse and I know when to reorder" is an extremely expensive and risky alternative to this mathematical formula.
Safety Stock — the untouched, reserve product balance in the warehouse whose sole operational purpose is to insure the business against sudden spikes in market demand or against the supplier overshooting logistical delivery deadlines. Here the operations manager constantly maintains a precise financial balance: less safety stock than needed raises the risk of an instant Stockout; more than needed means freezing the business's working capital on warehouse shelves.
Lead Time — the full calendar span of time from placing the official order with the supplier (or paying the invoice) until the goods physically arrive in your warehouse and are ready to sell. For international imports this figure (for example, 30 to 60+ days) fully dictates the company's entire financial planning. The longer the Lead Time, the earlier and the larger the Cash Flow with which the founder must make the purchasing management decision.
SKU (Stock Keeping Unit) — one specific, unique product position in the warehouse accounting system, identified down to the smallest detail (specific model + specific color + specific size). The SKU is the minimal, indivisible atom of commercial analytics. Margin, turnover and net profit should always be read at this level. Looking at "general, average" warehouse figures always hides the systemic problems that exist at this specific level.
Fulfillment — the full operational cycle of completing an order after the customer places it in chat or on the site: picking the right item off the warehouse shelf → packing it safely for commercial shipment → handing it over to the courier service on time → physical delivery to the customer. The operational cost and the error (failure) rate of each individual step should be measured as a separate metric, because every flaw is subtracted directly from the company's net margin.
Reverse Logistics — the operational process of the reverse movement of a parcel that the customer refused, did not accept, or returned, plus its accompanying hidden costs. In Georgian online stores working on cash on delivery (COD) this financial line is often completely invisible to the founder. In reality, every parcel with a "changed their mind / didn't answer" status adds up a double courier delivery-and-return fee, the loss of repackaging (materials), and the paid time of the warehouse employee.
Supplier Reliability — the real (not the one contractually promised on the invoice) percentage status of your partner supplier's or factory's adherence to deadlines and the stability of quality. An unstable, unpredictable supplier forces the business to artificially increase its Safety Stock in the warehouse, which directly means more cash pulled from your bank account and additionally frozen in goods. This is the hidden price of the partnership, never written on the initial invoice.
Demand Forecasting — the operational estimate of the likely sales volume for the coming calendar months, based on the business's historical sales, current ad activity and the seasonality factor of the market. Perfect mathematical precision does not exist in nature, but the basic operational model "real sales for the same month last year + the current business growth rate" is, in management terms, always a thousand times better than purchases based on intuitive gut feeling.
Stock Accuracy — the percentage figure that shows how precisely the digital balance recorded in the 1C/CRM accounting system matches the number of items physically present on the warehouse shelves. When this figure is "approximate" in a company, absolutely every upper management layer of running the business (calculating the Reorder Point, turnover, financial profit forecasts) is automatically built on "approximate" and creates large risks.
Overstock — the absolute opposite of an operational Stockout, and an equally dangerous management extreme: holding far more balance of a specific product position in the warehouse than current real market demand calls for. As a rule, Overstock appears because of an illusory "large-batch discount" offered by the supplier or out of the founder's fear. Excess inventory is the chief source of Dead Stock arising — what is simply excess in the warehouse today will, almost inevitably, turn into dead, depreciated goods tomorrow. There is one cure: run purchasing from a mathematical forecast, not from emotions.
Assortment / Product Mix — the structural composition of the full assortment present in the company's warehouse, analyzed in terms of each SKU's margin and turnover speed. The analysis clearly shows: what exact percentage share fast-turning, high-margin positions occupy in the warehouse, and what share goes to slow, low-margin goods. The term "a wide assortment and a big choice" is not in itself a value for the business — every new, added SKU raises the warehouse Carrying Costs and the operational management complexity in geometric progression.
Seasonal Stock — product positions that have a strictly limited, short calendar window for sale on the market (for example: New Year decorations, summer accessories). In managing these inventories everything is defined by two key dates: the last critical day on which an order placed with the supplier still makes it before the season starts (accounting for Lead Time), and the last calendar day on which selling these goods on the market is still possible at the full, initial commercial margin. Missing even one of these two dates automatically means forcing the inventory into a loss-making Markdown mode.
Cycle Count — the modern, effective alternative to the global, exhausting once-a-year warehouse inventory count (which requires a full operational shutdown of the business). It means regularly, continuously recounting small, pre-selected parts of the warehouse inventory every day or every week (for example, checking only 5 specific SKUs a day). With this method the real Stock Accuracy of the warehouse stays live and reliable throughout the whole year, and not only in the first week of January — at the moment the global count is completed.
Return Rate — the percentage share of orders fully sold and shipped from the warehouse that the customer returned, or did not physically accept from the courier on cash on delivery (COD). Formula: Return Rate % = (number of returned orders ÷ total number of orders shipped from the warehouse) × 100. This metric measures three crucial operational points at once: the real quality of the product, the accuracy of the visual promise made in the ad (ad photo vs received reality), and the inflated expectation artificially created by the operator in chat. A returned parcel is not just a lost sale — it is the direct cost of a double logistics fee, the loss of packaging materials and completely ruined unit economics, which is never reflected in the Facebook account's perfect ROAS.
On-Time Delivery Rate — the percentage share of orders shipped from the warehouse that the courier service delivered to the customer within exactly the time window the sales operator stated in chat. In Georgian e-commerce, where the largest part of sales happens on cash on delivery (paying the courier in hand), this metric is directly linked to the company's cash. The more calendar days or hours that pass between confirming the order in chat and the courier ringing the door, the more the probability grows geometrically that the item bought on an emotional impulse falls out of favor with the customer, who buys an alternative elsewhere or simply no longer opens the door to the courier. Late delivery is the chief — though rarely reflected in internal reports — cause of order cancellations and a catastrophic No-show rate.
Days of Inventory — an operational metric that simply shows how many more calendar days the current balance of physical goods in the warehouse will last the business, if the current average sales pace is maintained. Formula: Days of Inventory = the value (or units) of inventory in the warehouse ÷ the cost of goods sold per average day (or units). This is the practical, everyday operational language of Inventory Turnover. The phrase "we have exactly 45 days of stock left for this SKU" is far clearer and more action-oriented management information for a founder than dry annual ratios. Catching the right range is a strict balance: too few days means the risk of an instant Stockout at exactly the moment the ads are at their peak; too many days — capital frozen unmoving in the warehouse and rising Carrying Costs.
Order Accuracy — the percentage figure of correctly fulfilled orders that reached the end customer from the warehouse exactly as the customer arranged with the sales operator in chat: the exact model, the right size, the right color and full configuration (accessories, warranty, gift). Whereas Stock Accuracy measures the correctness of the warehouse's internal, digital accounting, Order Accuracy measures precisely what the customer physically received in hand. These are two completely different operational metrics. Every jumbled order sent incorrectly to a customer is a triple financial loss for the business: the return courier logistics of the refused item, a disappointed loyal customer (who will never buy from the company again) and the pointless spending of the operator's precious time on resolving the complaint.
