Why Stock Goes Wrong On Facebook
In a physical shop, a customer picks up the item and the shelf shows the change immediately. In Facebook selling, the “shelf” is a list somewhere, and the sale happens in a chat that is not connected to it. A busy day produces promises that nobody subtracts: three customers say yes to the last medium-sized shirt, and two of them are disappointed.
The cure is not complicated. It is one list that every order touches, a clear idea of what “in stock” means and a rhythm of checking the list against the shelf.
On Hand, Reserved And Available Are Three Different Numbers
On hand is what is physically on your shelf. Reserved is what you have promised to customers whose orders are not yet shipped. Available is on hand minus reserved, and it is the only number that should decide whether you say yes to a new order.
Many shops run into trouble because they count only what is on the shelf. When a customer confirms an order, take that quantity out of what you offer to the next customer immediately, even though the parcel has not left.
Steps To Manage Stock For A Facebook Shop
Work through these in order. Even the first four will remove most of the confusion.
List every item at variant level
A shirt is not one line; it is each size and colour. A food item is each pack size. Give every variant its own row and its own code, so “M, blue” is one thing and “L, blue” is another.
Give each variant a short code
Use a code you can write on the bag or shelf, such as SHIRT-BLU-M. A code removes arguments about which item is which, and you can add barcodes later.
Count everything once to start
Pick a quiet time and count the shelf. This opening count is your starting point; without it every later number is a guess.
Record every receipt
When stock arrives from a supplier, add it with the date, quantity and the cost per unit. Costs matter later when you work out profit.
Reserve stock when an order is confirmed
Take the quantity out of what is available as soon as the customer agrees, and release it again if the order is cancelled.
Record returns and damage
A returned item goes back to the shelf only after you have checked it. Damaged or lost items are written off with a reason, not just forgotten.
Count a few items every week
Check your best sellers and a few random items against the list weekly. Small, regular counts find mistakes while they are still small.
Set a reorder point for your best sellers
Decide how many days of stock you need while a new batch arrives, and reorder when the available quantity drops to that level.
A Tiny Example Of A Stock Record
The simplest useful record is a list of movements, not a single number that gets overwritten. Suppose you receive 20 blue shirts in size M. You sell 6, one customer returns 1 and you write off 1 damaged piece. The record reads: +20 received, −6 sold, +1 returned, −1 damaged, giving 14 on hand. If someone asks why the shelf has 14, you can show every step.
A single overwritten number cannot do that. When it is wrong, nobody can tell when it went wrong, so the mistake repeats. Keep the history, even in a spreadsheet, by adding rows instead of editing totals.
When A Customer Asks For Something That Is Out Of Stock
Say so quickly and offer something useful: another size or colour, a similar product or a date when it will be back. Honesty keeps the customer and keeps your reputation. A short Bangla answer works well: “দুঃখিত, M সাইজ এই মুহূর্তে স্টকে নেই। L সাইজ আছে, অথবা আগামী সপ্তাহে M আবার আসবে। জানাতে চান?”
Do not take an order for stock you do not have unless you tell the customer clearly that it is a pre-order, and when it will arrive.
Returns, Exchanges And Damaged Items
Returns are where stock records most often drift. When a parcel comes back, decide before it reaches the shelf: is it in sellable condition, does it need cleaning or repair, or is it lost? Only sellable items go back into available stock. An exchange is two movements, the returned item coming in and the replacement going out, so record both.
Make one person responsible for receiving returns, and put them in a separate place until they are checked. It sounds fussy, but it stops damaged goods from being sold to the next customer.
Notebook, Spreadsheet Or Software?
A notebook is fine for a handful of products. A spreadsheet works until two people edit it at once or an order is taken on the phone while you update the sheet on the laptop. The point where software pays for itself is when stock has to change automatically as orders arrive and every change has a trail.
Nabik.ai keeps stock per variant, reserves it when an order is created and records every receipt, sale, return and correction in a permanent ledger, so the balance is always computed and can always be explained. Low-stock alerts warn you before a popular size sells out, and Nabik AI answers “ache?” questions from the live numbers, so it never promises what you do not have. Products can be tracked as variants, by serial number or IMEI, by batch with expiry, or as a single item. If you sell on Shopify, WooCommerce, WordPress or Daraz as well, stock stays in sync across them.

Nabik AI answers your customers in Bangla, takes the order and keeps stock, couriers and accounts in one place.
Questions People Ask
How Do I Stop Selling Items That Are Out Of Stock?
Reserve stock when an order is confirmed and quote only the available quantity, which is what is on the shelf minus what is already promised. Count your best sellers regularly to catch mistakes.
How Often Should I Count My Stock?
Count everything once at the start, then check a few items every week, starting with the best sellers. A full count every few months is a good habit.
What Is A Reorder Point?
It is the stock level at which you order more, set so that new stock arrives before you run out. Base it on how fast an item sells and how long your supplier takes.
Can Nabik.ai Alert Me When Stock Is Low?
Yes. Nabik.ai shows low-stock alerts per variant, so you can reorder a popular size or colour before it sells out.
