Money and paperwork are not call times and cues
A business platform is organized around a client relationship: an inquiry arrives, a proposal goes out, an agreement gets signed, a retainer clears, and reminders go to the person paying. That arc runs from first contact to final invoice, and every screen assumes the reader is your client.
A run of show is organized around vendors who are not your clients and never will be. The hair and makeup artist needs a finish time. The rental company needs a pickup window and a gate code. The band needs a room ready time rather than a downbeat. None of those people belong in a client portal, and none of them will read a fourteen page document to find one line.
Where the wedding day usually ends up
Coordinators who run their business on a client platform almost always keep the wedding day schedule somewhere else: a spreadsheet, a document, sometimes a note in a shared drive. That is not a criticism of the platform. It is a sign that the two documents have different readers and different lifespans.
The trouble starts when the schedule leaves that file. Once a PDF has been emailed to fourteen people, you no longer control which version is on a kitchen counter at four in the afternoon. AisleTimeline exists to close that gap, and it sits happily beside whatever handles your contracts.
Running both across one wedding
In practice the split is simple. The business platform carries inquiry, agreement, payment schedule, and the final invoice. AisleTimeline picks up around the two week confirmation calls, when call times firm up and the schedule becomes something vendors act on.
Keep one rule and the two never collide: client facing dates live on the business side, vendor call times live in the run of show, and neither one is copied into the other. Copying is where a stale ceremony time gets introduced, and a stale ceremony time is how a photographer misses golden hour.
