Most Purchase Orders start because a show is short. When that's the case, build the Purchase Order from the Gear Order itself — LASSO carries the gear and the dates across for you.
Create the Purchase Order
Open your Gear Order.
Select the lines you need covered.
Click Create Purchase Order.
LASSO builds the Purchase Order with those lines already on it.
The Create Purchase Order window opens in a new tab with the dates filled in from the Gear Order. The warehouse matches the Gear Order and can't be changed. Pick your vendor, name the Purchase Order if you'd like, and click Create. Your lines are already on it.
Each line comes over sized to what's still uncovered: the shortage if there is one, or the rest of the line if not. Lines that a Purchase Order or Transfer Order already fully covers, and Quote Only lines, are left off. Rental lines come over as Subrental; sale lines come over as Equipment Purchase.
The Dates Come With It
You don't have to work out the dates by hand. LASSO sets them against the show:
Delivery: 24hrs before prep starts
In Service: one minute before prep starts, so the gear is available to the show that needs it
Out of Service: right after the show's return
Return: 24hrs after the show's return, giving you time to get it back to the vendor.
These are a sensible starting point, not a rule. If your vendor can only deliver on Tuesday, change it.
Keep Delivery and In Service before the show's prep ends, and Out of Service and Return no earlier than the show's return, so the gear covers the whole show. If you pick dates that don't, LASSO adjusts them when you create the Purchase Order. A later change that leaves the show uncovered still saves—LASSO marks the date with a warning icon instead. Hover or tap the icon to see the order and date it conflicts with. Dates that can't work—delivery after return, or In Service after Out of Service—show in red and must be fixed before the change saves.
If the Show's Dates Change
If you change a Gear Order's prep or return dates and a linked Purchase Order no longer covers them, LASSO shows Linked Purchase Orders Dates Impact with the Purchase Orders affected. Click Update PO dates to move those dates along with the show, or Cancel to undo your date change.
The Lines Stay Connected
Lines created this way stay tied to the show they came from. You'll see the Gear Order on each line and can click straight back to it.
Once on a PO, gear you subrented for one show can't quietly get reserved by a different one. It's earmarked.
Add Lines to a Purchase Order You Already Have
You can also add gear to a Purchase Order you've already started rather than creating a new one, which is handy when you're covering several shortages with the same vendor.
Select the lines on the Gear Order.
Click Subrent, then Add to Existing Purchase Order.
Pick the Purchase Order from the list. It only shows Purchase Orders that can take these lines: ones for this event (or not tied to an event yet), with dates that cover the show, and with a PO pack sheet that isn't Checked In yet. If you run more than one warehouse, each Purchase Order in the list shows its warehouse, so you can tell at a glance which one you're adding to.
LASSO checks the dates again and adds the lines, packages and all. The Purchase Order opens in a new tab.
Where to Look Next
Once the Purchase Order exists, your Gear Order's Qty Reserved updates to include it. It's worth reading about how subrentals feed your availability.
