Run your entire event rental business from one place

Retail inventory assumes stock is sold and gone. Rental stock leaves, comes back in a condition somebody has to record, and needs cleaning or repair before the next booking can have it. The whole model here is a count of interchangeable units moving through that loop, rather than a product that decrements to zero.

Not without somebody choosing to. A booking claims a count of units across a date range, and the next person to check those dates sees the reduced figure. Overriding the warning is possible, because a real business sometimes does it on purpose - but it is recorded on the booking, and the conflict shows up on the screen that lists what is contended.

Each item carries its own prep and cleaning days, and availability subtracts them. Linen back on Sunday with two days of turnaround is not offered for Monday, so the number you quote from is the number you can actually load.

Checking stock in is where you say what returned, what returned broken, and what is missing - the three reconcile against what went out, and an over-count is reported rather than quietly corrected. Damaged and missing are real pools, not a note in a comment field, so they come off availability until somebody resolves them.

Both. A booking's lines become a draft quote, a quote becomes an invoice, payments record against it, and a receipt is issued automatically for every posted payment including part-payments. Damaged items can be charged at their replacement price on the same document.
