Evaluate POS sync by the records that move and the business decision they support. “Real time” alone does not tell you whether a connection reads sales, updates sellable inventory, imports catalog data or keeps incoming purchases visible.
This is LineNow's documentation-based evaluation guide, reviewed September 4, 2026. It does not claim measured latency or comparative benchmark results for LineNow or another vendor. Use the same account configuration and scenario when collecting those results yourself.
Separate the records
| Record | Question the buyer needs answered |
|---|---|
| Completed sales and returns | What demand was recorded, and are canceled/refunded lines represented correctly? |
| Physical stock | What is actually on hand at each location? |
| Available-to-sell quantity | What remains after reservations and other stock rules? |
| Catalog and supplier mapping | Which variation and purchase unit does the record refer to? |
| Incoming purchase quantities | What is confirmed but has not arrived? |
| Receipts | Which event increased stock, and can it be traced to the order? |
Do not assume that reading a sale also writes a stock adjustment. If the POS already reduces inventory for that sale, repeating the decrement in a connected application can produce the wrong quantity.
