Every time you save a service template, VisionScaper stores a new immutable version. A quote, proposal, invoice or finished job keeps a frozen snapshot of the version it used. So changing a template later never changes a quote you have already made.

1. Open Services.
2. On a template row tap the clock icon (Version history).
3. The list shows each version, the date and who saved it. The current one is marked.
4. Tap View to read a version.
5. Tick two versions and tap Compare to see them side by side.

1. In Version history find the version you want.
2. Tap Restore.
3. Confirm. It becomes a new version (for example version 5), and the history is kept.

1. Edit the template. A Change note field says “Saving creates version N+1. Existing estimates, proposals, invoices and jobs keep the version they used.”
2. Write a short note, for example “raised mulch depth”.
3. Tap Save as new version. If nothing changed you see “No changes to save.”

When a quote section was made from a template that is now newer, you see: “This template has been updated since you added it (now v[n]) — apply the latest version?” with two buttons:

• Apply: replaces the section’s content with the newer template.
• Keep v[old]: keeps your version and hides the notice for that version.

This only appears while the quote is a Draft or a Request. After a quote is sent, viewed or signed it is frozen.

If you improved a section on a quote and want to reuse it:

• Save as template creates a new template from the section.
• Update template shows what changes, asks for a note, and writes a new version.

• Always write a change note. Future you will want it.
• Compare before restoring, so you pick the right one.

• No Restore button. You may be on the current version, or lack the right to edit.
• A signed quote did not update. By design, it keeps its version.
