The app syncs stock distributed across multiple locations.
Consider a scenario where 3 products, ProductA, ProductB, and ProductC, share the same SKU (they are physically the same item). Following is the location-wise inventory distribution configured on Shopify:
| LocationA | LocationB | LocationC | Total | |
| ProductA | 10 | 50 | 0 | 60 |
| ProductB | 10 | 10 | 40 | 60 |
| ProductC | 30 | 0 | 10 | 40 |
Let's say an order is placed for Product A for 20 units. Shopify will adjust the stock for product A as follows:
| LocationA | LocationB | LocationC | Total | |
| ProductA | 10 | 30 | 0 | 40 |
The Flo SKU Sync app will then force update the quantities of Product B and Product C to match Product A for each location. The inventory distribution will look as below:
| LocationA | LocationB | LocationC | Total | |
| ProductB | 10 | 30 | 0 | 40 |
| ProductC | 10 | 30 | 0 | 40 |
The app assumes that the physical items are the same, even if the product listings are duplicated. Hence, at all times, the stock levels should be the same across all locations.
