+
+This module introduces **Trips** in Expenses so employees can group
+related expense lines under a single business trip.
+
+Key features:
+
+-  Create trips with employee, date range, partner, and reason.
+-  Link existing expense lines to a trip from the trip form.
+-  Open linked expenses directly from the trip to review details.
+-  Optional manager approval flow before collecting receipts.
+-  Role-based access for employees, approvers, and administrators.
+-  Dedicated "Trip to Process" workspace for managers/approvers.
+-  Generate and attach a trip PDF report when the trip is marked done.
+-  Automatic bill creation from approved expenses with trip PDF
+   attachment.
+
+**Table of contents**
+
+.. contents::
+   :local:
+
+Usage
+=====
+
+1. Go to *Expenses > My Trips* and create a new trip.
+2. Fill in the trip name, dates, employee, and optional partner/reason.
+3. Click *Request Approval*: In this step, pre-trip approvals can be
+   handled, and additional workflows can be triggered after approval
+   (for example an A1 certificate process).
+
+   -  If **Auto Approve Trip Requests** is enabled, the trip moves
+      directly to *Collect Receipts*.
+   -  Otherwise, if the requester is already an allowed approver for
+      that trip, it is approved immediately without creating an
+      activity.
+   -  Otherwise, a *Trip Approval Request* activity is created for the
+      manager.
+
+4. In the *Expenses* tab, use *Add* to select existing draft expenses
+   for the same employee, then save.
+5. Click an expense line to open the *hr.expense* form when you need to
+   review or edit that expense.
+6. When all expenses are complete, click *Mark as Done* to finalize the
+   trip and attach the generated trip report in chatter.
+7. To create bills from approved expenses, click *Create Bill* (visible
+   only when trip is in state done all expenses are in approved state).
+   This will post all expenses and attach the trip PDF to each resulting
+   bill.
+
+Role behavior
+-------------
+
+-  Employees can create and edit their own trips.
+-  Managers/approvers can view and approve trips they are responsible
+   for.
+-  Expense administrators can edit all trips.
+-  After a trip is approved, only managers/administrators can edit trip
+   information.
+-  The *Expenses* tab remains editable until the trip reaches *Done*.
+
+Manager processing menu
+-----------------------
+
+Managers can open *Expenses > Trip to Process* to review requested trips
+where they are responsible as manager.
+
+Create Bill feature
+-------------------
+
+The *Create Bill* button is automatically displayed when all expenses
+linked to the trip are in approved state and the trip is in state done.
+Clicking this button will:
+
+1. Post all approved expenses and create bills.
+2. Automatically attach the trip PDF report to each created bill in the
+   chatter.
+3. Navigate to the created bill(s) for review.
+
+This streamlines the billing process by ensuring the trip documentation
+is automatically associated with the financial records.
+
+Configuration
+-------------
+
+To configure auto approval, go to *Expenses > Configuration > Settings*
+and in the *Trips* section enable or disable *Auto Approve Trip
+Requests*.

+This module introduces **Trips** in Expenses so employees can group related
+expense lines under a single business trip.
+
+Key features:
+
+- Create trips with employee, date range, partner, and reason.
+- Link existing expense lines to a trip from the trip form.
+- Open linked expenses directly from the trip to review details.
+- Optional manager approval flow before collecting receipts.
+- Role-based access for employees, approvers, and administrators.
+- Dedicated "Trip to Process" workspace for managers/approvers.
+- Generate and attach a trip PDF report when the trip is marked done.
+- Automatic bill creation from approved expenses with trip PDF attachment.

+1. Go to *Expenses > My Trips* and create a new trip.
+2. Fill in the trip name, dates, employee, and optional partner/reason.
+3. Click *Request Approval*:
+   In this step, pre-trip approvals can be handled, and additional workflows
+   can be triggered after approval (for example an A1 certificate process).
+   - If **Auto Approve Trip Requests** is enabled, the trip moves directly to
+     *Collect Receipts*.
+   - Otherwise, if the requester is already an allowed approver for that trip,
+     it is approved immediately without creating an activity.
+   - Otherwise, a *Trip Approval Request* activity is created for the manager.
+4. In the *Expenses* tab, use *Add* to select existing draft expenses for the
+   same employee, then save.
+5. Click an expense line to open the *hr.expense* form when you need to review
+   or edit that expense.
+6. When all expenses are complete, click *Mark as Done* to finalize the trip
+   and attach the generated trip report in chatter.
+7. To create bills from approved expenses, click *Create Bill* (visible only
+   when trip is in state done all expenses are in approved state). This will 
+   post all expenses and attach the trip PDF to each resulting bill.
+
+
+Role behavior
+-------------
+
+- Employees can create and edit their own trips.
+- Managers/approvers can view and approve trips they are responsible for.
+- Expense administrators can edit all trips.
+- After a trip is approved, only managers/administrators can edit trip
+  information.
+- The *Expenses* tab remains editable until the trip reaches *Done*.
+
+Manager processing menu
+-----------------------
+
+Managers can open *Expenses > Trip to Process* to review requested trips where
+they are responsible as manager.
+
+Create Bill feature
+-------------------
+
+The *Create Bill* button is automatically displayed when all expenses linked to
+the trip are in approved state and the trip is in state done. Clicking this button will:
+
+1. Post all approved expenses and create bills.
+2. Automatically attach the trip PDF report to each created bill in the chatter.
+3. Navigate to the created bill(s) for review.
+
+This streamlines the billing process by ensuring the trip documentation is
+automatically associated with the financial records.
+
+Configuration
+-------------
+
+To configure auto approval, go to *Expenses > Configuration > Settings* and in
+the *Trips* section enable or disable *Auto Approve Trip Requests*.

+<li>Go to <em>Expenses &gt; My Trips</em> and create a new trip.</li>
+<li>Fill in the trip name, dates, employee, and optional partner/reason.</li>
+<li>Click <em>Request Approval</em>: In this step, pre-trip approvals can be
+handled, and additional workflows can be triggered after approval
+(for example an A1 certificate process).<ul>
+<li>If <strong>Auto Approve Trip Requests</strong> is enabled, the trip moves
+directly to <em>Collect Receipts</em>.</li>
+<li>Otherwise, if the requester is already an allowed approver for
+that trip, it is approved immediately without creating an
+activity.</li>
+<li>Otherwise, a <em>Trip Approval Request</em> activity is created for the
+manager.</li>
+</ul>
+</li>
+<li>In the <em>Expenses</em> tab, use <em>Add</em> to select existing draft expenses
+for the same employee, then save.</li>
+<li>Click an expense line to open the <em>hr.expense</em> form when you need to
+review or edit that expense.</li>
+<li>When all expenses are complete, click <em>Mark as Done</em> to finalize the
+trip and attach the generated trip report in chatter.</li>
+<li>To create bills from approved expenses, click <em>Create Bill</em> (visible
+only when trip is in state done all expenses are in approved state).
+This will post all expenses and attach the trip PDF to each resulting
+bill.</li>
