Budget detail

Full view of one budget: header with patient info, a main column with the line items and totals, and a sidebar with actions, metadata, and the payments card contributed by the payments module. This is where the budget moves through draft → sent → accepted and gets signed, invoiced, or renegotiated.

At a glance

• Two-column layout. Left: budget line items with catalog item, tooth, surfaces, quantity, discount, and VAT. Right (top to bottom): payments card (slot budget.detail.sidebar, filled by payments), totals (subtotal, discount, VAT, total), info (number, version, validity, creator, linked plan).
• Status chip in the header. Available actions depend on it.
• Versioning. Each renegotiation creates a new version linked via parent_budget_id; history is shown under Version history.
• Signature and PDFs. An accepted budget stores a BudgetSignature plus a signed PDF whose SHA-256 is kept as a tamper-evident hash. Two downloads exist: unsigned PDF and signed PDF.
• Create invoice. When the budget is accepted and still has uninvoiced items, a Create invoice button appears and takes you to /invoices/from-budget/{id}.

Edit lines

Requires budget.write and draft status.

1. Click Edit on a line or Add item below the table.
2. Change catalog item, tooth, surfaces, quantity, discount, or VAT. Totals recompute on save.
3. The backend rewrites the totals invariant on save (no update event yet).

Send to the patient

Requires budget.write.

1. Click Send to patient. The budget transitions to sent, a public code is generated, and the email goes out.
2. budget.sent is published so messaging modules can complement the email.
3. The sidebar then shows the public link card with the verification code.

Accept or reject

Requires budget.write for online acceptance, budget.accept_in_clinic for in-clinic signed acceptance.

1. Accept (online) — used when the patient accepts via the public link. Creates a BudgetSignature and a signed PDF. Publishes budget.accepted.
2. Accept in clinic — button only visible with the matching permission. Opens the tablet signature modal (drawn signature). Same result as the online acceptance.
3. Reject — records a reason and publishes budget.rejected.

Renegotiate

Requires budget.renegotiate.

1. Click Renegotiate. Creates a new version linked to the current one; the previous becomes historical.
2. Edit items and save. Publishes budget.renegotiated.

Troubleshooting

• No Create invoice button. The budget is not accepted yet (valid: accepted), or it already has a non-cancelled invoice, or every item is already invoiced (invoiced_quantity == quantity).
• Cannot edit lines. The budget is no longer in draft. To change prices or quantities on a sent/accepted budget you must renegotiate (requires budget.renegotiate).
• No payments card. The payments module is not installed. The sidebar shows only totals and info.
• Signed PDF returns 404. The budget is not accepted yet — the signed PDF only exists from the accepted state on.
