InvoiceCreateView.post delegated to get() when the form was invalid, and FormMixin.get_context_data then built a *second* bound form, because get_form_kwargs keys off request.method. Rendering it re-ran full_clean(), so the errors displayed came from a second read of the database -- and if the state changed back in between, the page rendered with no error at all while nothing was saved. The service-delivery total check landing next is exactly such a state-dependent validation. form_invalid(form) renders the form it is handed, so there is now one form and one validation pass. self.object = None is what BaseCreateView.post sets before delegating, and this custom post() never did.

…was previewed The amount field is server-filled from the preview endpoint, so a posted total that no longer matches the window means the deliveries moved -- an approval landed, or an automated run billed the delta. Saving silently handed the NM an invoice for a figure they never reviewed. clean() recomputes through get_billable_line_items, the same call the preview makes, so a mismatch is always real state change and never representation drift. Nothing is written on rejection and the re-rendered page re-fetches the corrected figures. This is the readable error, not the guarantee: it reads before save's locked read, which is why save takes its totals from the frozen rows and never from the posted amount.

fetchInvoiceLineItems' .catch hid the download button but left amount, amount_usd and the table untouched, so a failed re-fetch showed the previous window's total and rows against the newly chosen dates -- figures never priced for that period. Both are cleared now. The failure was also invisible: it only reached the console, and since the amount field is read-only and server-filled, the only feedback was "This field is required" on a field the NM cannot type into. The catch now raises lineItemsError, which shows a banner with a Retry button and disables Submit. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
AutomatedPaymentInvoiceForm.line_items built its fieldset from three inline HTML strings,
which CLAUDE.md rules out and which split the markup from the code driving it: the ids it
declares and the Alpine flags it binds are owned by partials/invoice_form_handler.html.
The body moves to partials/invoice_line_items_fieldset.html, branching on
form.line_items_table exactly as the property did; crispy's HTML() compiles its string as a
Template against the page context, so both {% include %} and form resolve.

Deliveries can keep coming today and in future and end date will not cover them is misleading. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
get_start_date_for_invoice and _bill_opportunity ran inside the loop with no error handling, so one opportunity that raises -- no exchange rate for a billed month, say -- aborted the whole run. The opportunities already billed kept their frozen rows and advanced watermarks, but _send_auto_invoice_created_notification never ran, so nobody was told those invoices existed. Catch per opportunity, report to Sentry, and continue, so the failure is one opportunity's problem rather than the run's. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The Alpine state took the amount through `|default:'null'`, which substitutes on any falsy value -- so a 0.00 invoice reached the page as the string "null". `x-model` then wrote that into the amount input, and a `type="number"` field rejects it, so the box rendered empty with no way to tell a zero invoice from a failure to load. `default_if_none` passes 0.00 through and still yields the "null" sentinel when there genuinely is no amount yet. Pre-existing, but service-delivery invoices now save as 0 for a period with nothing billable, so it went from a corner case to a normal outcome. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
… table Cancelling or rejecting a service-delivery invoice deletes its frozen line items so the deliveries become billable again, and a period with nothing billable produces an invoice with no rows at all. Both rendered as a table of headers with no data, which reads as a page that failed to load -- and the two cases mean completely different things to whoever opens the invoice. The empty table is replaced with a message that distinguishes them, driven by `line_items_released` so the status test stays in Python rather than the template.

WalkthroughService-delivery invoice forms reject end dates on or after the local current date and submitted amounts that differ from current billable totals. The form displays line-item loading, error, empty, and populated states. Invalid submissions preserve the bound form and validation errors. Automated invoice generation logs per-opportunity failures and continues processing later opportunities. Tests cover invoice snapshots, validation, empty billing results, and batch continuation. Priority: ➖ Normal Estimated code review effort: 3 (Moderate) | ~25 minutes Change: Bug fix Merge Risk: 🟡 Moderate · up to Invoice creation can save an amount different from the one submitted if billable work changes during submission. Preview races can also disable Submit, and a partial monthly invoicing failure can appear as a successful run. Resolve or explicitly accept these risks before merging.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Ignore stale invoice line-item responses.
When either service-delivery date changes, fetchInvoiceLineItems() starts another request without invalidating the previous request. An older failure can clear the newer preview, clear totals, and disable Submit. An older success can overwrite the newer line items, totals, and late-delivery count. Apply success, failure, and finally state changes only for the latest request.

Review comments at @commcare_connect/opportunity/forms.py:
- Around line 1745-1747: Move the end-date maximum out of the class-level
Meta.widgets configuration and set self.fields["end_date"].widget.attrs["max"]
in the form’s __init__ after super().__init__(), so each form uses the current
local date minus one day.
- Around line 2052-2055: Update _reject_stale_total and the save flow so the
submitted amount is compared with the billable rows selected under the billing
lock, before those rows are frozen; reject the submission when the locked total
differs, rather than validating against an earlier unlocked read.
Review comments at @commcare_connect/opportunity/tasks.py:
- Around line 712-716: Update generate_automated_service_delivery_invoice to
collect failures when _bill_opportunity raises, while retaining the
per-opportunity exception log and continuing to process later opportunities and
send their notifications. After the loop, report the collected failures through
the job’s existing failure mechanism so the run does not finish as successful.
Review comments at @commcare_connect/opportunity/tests/test_tasks.py:
- Around line 416-417: Control the task iteration order in the test using the
`failing` and `billable` opportunities so `failing` is processed first and
`billable` afterward; do not rely on factory creation order because the queryset
has no guaranteed ordering.

Product Description
Follow up PR to the invoice line items work
Fixes to the invoice form and the invoice page, found while working on the line-item change in #1425. Most are pre-existing bugs(minor nothing critical) rather than anything the new billing code introduced.
What this PR does
Fixes:
Improvements:
In case the invoice was cancelled
No deliveries found
Worth reviewing commit by commit.
Technical Summary
https://dimagi.atlassian.net/browse/CCCT-2856
Safety Assurance
Safety story
No database changes. Everything here is either a form validation, a template change or an error-handling change, so a defect is a code revert.
The riskiest one is rejecting a total that no longer matches the period, because it can block a submit. It only triggers when the deliveries genuinely changed since the form was opened, and the page re-fetches so the NM can submit the corrected figures straight away.
Two of these need the earlier parts of the stack (the total check and the monthly task fix). The rest apply on their own.
Automated test coverage
pytest commcare_connect/opportunity— 652 passed.prek run -aclean.Covers the window rules (period must be finished, end after start, no future end), the posted total never being trusted, a stale total being rejected, an invalid submit rendering its own errors once, a zero invoice showing 0 rather than a blank, the empty-table message for both cases, and one opportunity failing without stopping the monthly run.
QA Plan
QA to be considered as it has some UI changes.
