| Layby started at the counter | Paper slip, item tagged in the back room | Unit reserved in every channel instantly | This is the most important rule. If the website can still sell it, the layby is not really reserved. |
| Layby started online | Not offered, or a manual email exchange | Deposit taken at checkout, agreement emailed | Usually needs an app or custom checkout step, since most ecommerce platforms do not offer true layby natively. |
| Started in one store, paid in another | Customer sent back to the original store | Payment posted to the shared layby record | Requires a single layby ledger across stores, which some POS systems provide and some do not. |
| Started online, collected in store | Store has no record of the online layby | Goods reserved at the nominated store | Different from click and collect: the hold lasts weeks, and the final payment, not the order, triggers release. |
| Instalment comes due | Staff ring customers from a list | Reminder with a pay link sent automatically | A pay link lets the customer pay from their phone instead of coming into the store or ringing up. |
| Customer cancels halfway | Refund worked out on a calculator | Refund less permitted charge, stock released | The charge must be in the written agreement, applies only when the customer cancels, and cannot exceed reasonable costs. The system applies it consistently. |
| Final payment made | Sale rung up again at the till | Liability converts to a sale, goods released | Ringing the sale up again is a classic source of double counted revenue and wrong GST figures. |
| Year end and stocktake | Layby shelf counted separately, book rebuilt | Layby book and reserved stock reported | Accountants ask for the layby book. Counters need to know which units are committed. |
