The longer answer
Check headroom first
Standard track needs roughly twelve inches above the opening. Plenty of plans in this region come in under that once the header and any mechanical runs are in. The fix is low-headroom track, specified up front so nobody finds the problem on install day.
Price the base door and the upgrades together
Price a base steel door and the community's top carriage-house option together, so the buyer's upgrade is a line item on the original contract. Carrying several manufacturer lines makes that range possible from one supplier.
Order to the build calendar
The door should arrive after drywall and before final. Ordering to the build calendar keeps it off the critical path.
Openers at handover
Installing a smart-capable opener with battery backup during the build means the buyer sets it up from a phone on day one, and it heads off a predictable warranty call in month three.
