Execution. Trestle runs projects that are already approved and funded, and reads authorization and budget from your financial system.
Yes. Each external organization gets portal logins with per-contact permissions, submits against a contract or purchase order, and tracks approval through to payment.
Daily at minimum, and event driven where a workflow needs it. One way or two way depending on which system owns the value.
No. Trestle browses it in context, writes generated documents back to it, keeps folder structures aligned and archives at closeout.
Scoped to your program: user mix, integration count, migration volume and training. You get a written scope and proposal after discovery.
