A backorder is an order you accept for an item that is out of stock right now but has stock on its way. Handled well, it keeps a customer who would otherwise leave. Handled badly, it becomes a cancellation, a refund and a one-star review. This guide covers how Indian retailers can run backorders without losing the customer or the margin.

Is an out-of-stock item always a lost sale?

No. A shopper who lands on a sold-out product usually leaves because the page gives no next step, not because they refuse to wait. A clear restock date and a simple promise turns many of those visits into orders.

Most stores handle sold-out items in one of two ways. They either hide the product, so the shopper bounces to a competitor, or they quietly keep selling it and hope stock arrives in time. The second is worse. The customer pays, hears nothing for a week, and then gets a cancellation email. You lose the sale and you also pay for the payment gateway and the support call.

The fix is to treat a backorder as a proper order state with its own rules, not as an accident. That means three decisions made in advance: which items may be backordered, how many units you will promise against stock that has not arrived, and what the customer is told at each step.

Which items should you allow on backorder?

Allow backorders only on items where you hold a confirmed purchase order or a dependable supplier cycle. Never open backorders on items with no inbound stock, because that is just overselling with a polite label.

Sort your catalogue into three groups:

The reason for the third rule is simple. A backorder is a promise, and a promise on stock that may never arrive is how a retailer ends up with the cancellations described in how order cancellations strand stock.

How many units can you safely promise?

Promise no more than the quantity confirmed on the inbound purchase order, minus a small buffer. The number you promise against must come from stock that is genuinely coming, not from a guess.

Many retailers make the mistake of keeping the backorder open with no limit. One popular item then collects forty waiting orders against a purchase order of twenty. Half the customers are disappointed the day the shipment lands.

A workable rule: take the confirmed inbound quantity, hold back a margin for damaged or short-shipped units, and cap the backorder at what is left. If the supplier shorts you, the buffer absorbs it. If the stock comes in clean, the buffer goes back on the shelf as normal available stock.

This only works if you can see three numbers separately for each product: what is on hand, what is already reserved for orders, and what is incoming. When those sit in different spreadsheets, or different channels each hold their own count, the cap is meaningless. This is the same single-count problem behind overselling on Amazon, Flipkart and Meesho.

How to run a backorder from order to dispatch

A backorder needs a short, fixed sequence so that nobody on your team improvises. Here is a sequence that works for most Indian retailers selling online and in store.

  1. Mark the product as backorderable only after the supplier confirms the quantity and delivery date in writing.
  2. Show the expected restock date on the product page, in plain words, for example "Ships by 3 November".
  3. Reserve incoming units for waiting orders in the order they were placed, so earlier customers are served first.
  4. Send the customer a confirmation that states the date, the refund rule and how to cancel for free.
  5. Receive and put away the stock the same day it arrives, then release the waiting orders to picking right away.
  6. Message every waiting customer when their order moves to dispatch, and message them early if the date slips.
  7. Review the backorder log weekly and remove the item from backorder if it slipped twice.

Step five is where most backorders fail quietly. Stock is physically in the building but nobody has put it away, so the system still shows zero and the waiting orders sit idle. The mechanics are covered in how putaway delays hide sellable stock.

What should you tell the customer, and when?

Tell the customer three things at the time of order: the real ship date, what happens if the date slips, and that they can cancel for a full refund. Then update them at every change, before they have to ask.

Silence is what customers punish, not the wait itself. A short WhatsApp or SMS at three moments covers almost everything:

Be careful with refunds. Gateways and banks follow payment-system rules set by the regulator, so a refund promise on your page should match what your gateway can actually deliver. The Reserve Bank of India publishes the directions that payment providers work under, and your gateway's own refund timeline is the number to quote. Do not promise "instant refund" unless your gateway confirms it.

Should you split a backorder across shipments?

Only if the customer agrees. A shopper who ordered three items, one of them backordered, should be asked whether to ship the two available items now or wait and ship everything together.

Splitting without asking doubles your freight and frustrates customers who wanted one parcel. Splitting with consent, and with a clear rule on who pays the second shipment, protects your margin. The cost side is worked through in how Indian retailers handle split orders without losing margin.

Where you have several stores or a warehouse, check whether the item is sitting at another location before you backorder it. Moving a unit between locations is often faster than waiting for the supplier. That check is the core of preventing stock-outs across multiple locations.

How do you keep backorders from hurting your festive rush?

Cap backorders harder in peak weeks, because a late shipment in a festival window is a failed gift. Anything promised for a festive date should only be backordered if the stock is already confirmed to land at least a few days before the cut-off.

Set your order cut-off so that backorders released from stock still meet the courier pickup, as described in setting order cut-off times that ship on time. India's retail sector keeps shifting more of its buying online, as the India Brand Equity Foundation's retail overview tracks, so expectations on delivery promises only tighten. Industry bodies such as the Retailers Association of India are a useful place to compare notes with other store owners on these practices.

What does a backorder system need to track?

At minimum, one place that shows on-hand, reserved and incoming quantities for every product, across every channel, and a queue of waiting orders ranked by date. Without that, backorders turn into spreadsheet chasing.

Commmerce is an Omnichannel Retail Operating System for Indian retailers. Its order management keeps a single stock ledger for store, website and marketplaces, tracks incoming stock alongside available stock, and reserves stock for an order at the moment it is placed. Because all channels read one available number, two channels cannot promise the same incoming unit to different customers.

Whatever tool you use, judge it on three questions. Does it show incoming stock separately from available stock? Does it release waiting orders automatically when stock is received? Does every channel read the same number? If any answer is no, backorders will leak.

Frequently asked questions

Yes, as long as you state the expected ship date clearly before payment and honour a reasonable cancellation and refund. Check invoicing timing with your chartered accountant against the rules on cbic-gst.gov.in.

Should I take payment upfront on a backorder?

For low-value items, yes, since it reduces cancellations. For high-value items or uncertain stock, consider cash on delivery with a confirmation call, or a small advance.

How long can a backorder wait before I should cancel it?

Set a limit when you open the backorder, and stick to it. If the date has slipped twice, stop taking new backorders on that item and offer waiting customers a cancellation.

Do marketplaces allow backorders?

Marketplace listings generally need stock to show as available, so backorder promises are best kept to your own website and store. Do not list stock on a marketplace that you do not physically hold.
