Every subcontractor and crew member, one project, one record
A GC's problem isn't getting photos — it's that they exist across eight different phones belonging to people who don't work for the GC. Progress lives in group texts, a sub says they were never told about a change, and nobody can say for certain who was actually on site on a given day. OnsiteSync puts every sub and crew member into the same project, posting directly, with roles that keep control where it belongs without making coverage expensive.
Free during early access — no credit card required.
How Collaborators work in OnsiteSync
From the photo on the job site to the report you hand someone.
Invite anyone to a project
A sub, a crew member, an inspector — add them with an email, no onboarding call required on either end.
Set their role on the way in
Chosen the moment they're invited: a Contributor sees and posts to their own work, while a Manager or Admin sees everything in the project, across every sub and crew member.
They post directly
A sub photographs and logs their own work, instead of texting it to someone who re-enters it for them.
Everything lands in one project
No separate thread per sub to reconcile at the end of the week — one record, however many people are contributing to it.
Contributors stay free
Crew and subs never count against your seat count, so coverage isn't rationed by who you can afford to add.
Remove access without losing the record
Take someone off a project and their photos and log entries stay exactly where they were.
What this actually settles
Every one of these comes down to whether a dated photo and a status exist.
- A sub insists they were never told about a change order, and the project record shows exactly who posted what and when.
- An owner asks who's been on site this week, and the project's contributor list answers it without a phone call.
- A GC stops re-typing updates a sub already texted, because the sub posted it directly into the project.
- A dispute over one trade's schedule slip gets settled by who actually logged work on which days, not memory.
- A Contributor sees their own work and nothing more — not another sub's pricing conversation or a competitor's progress — while the GC's Managers and Admins see the whole project, every trade included.
- A new Manager or Admin coming onto a job sees the full history on day one, while a new Contributor only adds to it going forward — nobody has to explain who did what before they showed up.
