Inventory and POS Integration
The online store and the counter POS reading and updating the same stock figure, so an item sold at the counter cannot also be sold online a moment later. Built and run by GullySystem.
Why the Website and the Counter Disagree About Stock
The website often reads from a stock figure someone updates once a day, while the counter POS updates in real time as items are billed. An item sold at the counter in the morning can still show as available online in the afternoon, and the cancellation that follows costs a customer's trust, and on a marketplace, your seller rating too.
What Inventory and POS Integration Covers
Real-Time Stock Sync
A sale at the counter reduces the online stock figure immediately, and an online order reserves stock the moment it is confirmed.
Multi-Store Stock Visibility
Stock across several store locations and a central warehouse is shown together, so an online order can be fulfilled from whichever location holds it.
Store Pickup as a Delivery Option
A customer can order online and collect at a specific store, drawing from that store's own counter stock.
Product and Price Consistency
Item codes, descriptions and prices are kept consistent between the POS and the online catalogue, so a price change made once applies everywhere.
An Example: A Footwear Chain Selling at the Counter and Online
A footwear chain bills each pair at the counter on POS software installed at every showroom, and also runs an online store that, until now, worked from a manual stock count updated weekly. Connecting both systems means a pair sold at any showroom counter is removed from the online listing within the same transaction, and an online order can be routed to the nearest showroom holding that size for same-day pickup instead of shipping from a warehouse that may not have it.
What Shapes the Cost and Timeline of a POS Integration
- Which POS or counter billing software you currently use and whether it has an API
- How many store locations and warehouses need to be connected
- Whether store pickup and inter-store transfer are required, or stock visibility alone is enough
- How product and pricing data is currently structured in your POS
- Whether stock needs to sync instantly or a short delay is acceptable
Frequently asked questions
Do we need this if we only sell online, with no physical counter?
No, this integration is specifically for businesses selling at a physical counter and online at the same time. An online-only business has no counter stock figure to reconcile against.
What makes this integration cost more for one POS system than another?
Whether your POS software offers a documented API. A POS with no API needs a workaround such as a scheduled export, which costs more to build and maintain than a direct connection.
What typically takes the longest?
Mapping your existing product codes and categories between the POS and the online catalogue correctly, because mismatched codes cause stock errors after launch.
Will this replace our POS software?
No, it connects to your existing POS rather than replacing it, so your counter staff keep using the billing software they already know.
Who owns the combined stock data once this is set up?
You do. The stock figure lives in systems you control, and export is always available.
What details do we need to provide before this starts?
Details of your current POS software and whether it has an API, your store and warehouse locations, and your current product code list.
