Bill your retainage, void a bad draft, and send the whole pay-app package

The last 5–10% of a job's money — the retainage the GC has been holding — can now be billed through STrOp. When Closeout shows a project past its 35-day release window, the Retainage tab has a Create retention application button: it opens a new pay application prefilled to release the full held amount (adjust it for a partial release), flows into your AR like any other application, and can be flagged Final to close out billing on the contract. The printed application shows retainage held net of releases and calls out the released amount.

Billing also picked up the fixes a live billing cycle asks for:

  • Void. A draft or submitted application you don't want anymore can be voided — it drops out of billing history and AR, and the next application numbers correctly past it. Paid applications can't be voided; an accepted one walks back through "GC Revised" first.
  • Your history stays put. A submitted application's printed numbers are frozen with it — editing the Schedule of Values later (or executing a change order against a line) changes future applications, never a certificate you already sent.
  • Change orders land on open drafts. Executing a CO that adds an SOV line now puts that line on any application still in draft, so it's billable this period — no recreating the app.
  • The package. In California the conditional waiver travels with the application. The new Package button prints application + continuation sheet + the linked §8132/§8136 waiver as one job — and every application now carries a Contractor's Certification signature block (add a notary acknowledgment with one click when a GC wants it notarized).
