# Multi-Store Fragmentation Cost Estimator

 

Running stores and channels on separate systems has a monthly price: the hours spent reconciling stock, plus the orders lost to overselling. Put in your own numbers to size it. This is a model, not a benchmark.

It is an estimate to help you size your own reconciliation and overselling burden, not a measured statistic. Verify against your own records before acting.    

## How the Multi-Store Fragmentation Cost Estimator works

 

When each store and each sales channel runs on its own system, two costs appear every month. The first is labour: staff manually checking and reconciling stock so the separate systems agree. The second is overselling: selling a unit on one channel that another channel already sold, which turns into cancellations, penalties and lost customers.

 

This tool estimates both from your own inputs. Reconciliation labour is your stores times manual checks per store per day times minutes per check, spread across your working month and priced at your staff cost per hour. Overselling cost is your incidents per month times your average cost per incident. It also shows the number of independent stock pools you are keeping in sync, which is simply stores times channels.

 

### Worked example

 

An 8-store chain selling across POS, a website and two marketplaces (4 channels) has up to 32 independent stock pools. At 15 checks per store per day of 3 minutes each, that is 6 hours of stock-checking per store per day; across 8 stores, 26 days and a staff cost of ₹150 per hour, reconciliation labour alone is a substantial monthly figure, before adding 20 overselling incidents at ₹400 each. Enter your own numbers above to see your estimate.

 

## Frequently asked questions

  Is this based on real benchmark data?

No. This is a model: every figure it returns comes from the numbers you enter. It contains no survey data or industry averages, so treat the output as a structured estimate for your own operation, not a published benchmark.

 What counts as a channel?

Any place a unit of stock can be sold or committed: your in-store POS, your online store, and each marketplace such as Amazon or Flipkart. A chain with 8 stores selling on POS, a website and two marketplaces has up to 8 times 4 independent stock pools to keep in sync.

 How is the reconciliation cost calculated?

Stores times manual stock checks per store per day times minutes per check gives daily minutes, multiplied across your working month and priced at your staff cost per hour. It is the labour spent keeping separate systems agreeing, before any overselling.

 What is the overselling cost?

Overselling incidents per month times your average cost per incident. That cost is whatever a cancelled or unfulfillable order actually costs you: marketplace penalty, refund handling, the lost customer, and the staff time to sort it out.

 How would unifying systems change this?

A single real-time inventory across stores, website and marketplaces removes most manual reconciliation and the overselling that stale stock causes. The estimate is meant to size that gap for your business so you can compare it against the cost of fixing it.

### One real-time inventory across every store and channel

 

Commmerce keeps stock, orders and billing in sync across POS, your online store and marketplaces, so the reconciliation and overselling this tool estimates largely disappears.
