Warranty days count from the order’s warranty start date, and that
date is the day the order was delivered. Cover is keyed off delivery on every
order — not off the day an installation was finished.

Why delivery and not installation
Delivery is when the customer takes possession of the goods, so it is when the warranty
obligation begins. It is also a date you already record, on every order, whether or not anyone
installs anything — which makes it the one date that is always available and always means the
same thing. Keying cover off an installation date would leave supply-only orders with no clock
at all, and would let a late installation quietly extend a warranty.

How the date is worked out

Once an order is Confirmed, the warranty start date is set automatically from the
latest delivery date across the order’s confirmed items, with the basis
reading Supply only (delivery). Both values are stored and used as before; the Order
Header no longer displays them next to the Warranty combo — their labels are
hidden (owner decision), so only the Warranty combo itself shows on that row.

Why the latest delivery date
An order can be delivered in more than one drop. Using the earliest would start the clock before
some items were even on site, shortening the cover the customer paid for. The latest date is the
point at which the whole order was delivered.

What this means day to day

  • Supply-only and supply-and-install orders behave identically for warranty
    purposes. The order type’s install flag does not affect the clock.
  • Marking an installation complete does not start or move the warranty. If an
    installation runs weeks after delivery, the warranty is already running — it started when the
    goods arrived.
  • An order that has no delivery dates yet on its confirmed items has no warranty
    start date, and its service lines will read “cannot determine” until it does.
The clock is stamped once and does not move
After the start date is set it stays put. If a delivery date is corrected afterwards, the
warranty start does not follow it — deliberately, so a warranty cannot silently shift
under a customer. If a start date is genuinely wrong, change it on the order on purpose.
If you see an older basis
Orders stamped before this changed may show a basis of Installation complete or
Manual. Those dates are left exactly as they were — the warranty a customer was already
sold does not change. Only newly stamped orders use delivery.
