 **Billing:** Always ask for minutes and labor type before adding any line item. Never assume a default.
 
+**Emergency/after-hours billing — check prepaid first:** Before adding a `26184` (Emergency) line item, `GET /customers/<id>` and read `prepay_hours`. If `prepay_hours > 0`, the customer has a prepaid block — bill `26118` (Onsite) at `quantity × 1.5` instead (prepaid debits by quantity, not by dollars). Never stack `26118` + `26184` for the same hours — the Emergency product rate already has the 1.5× multiplier baked in.

+**Line-item `price_retail` MUST be set explicitly:** Earlier guidance to "omit `price_retail` and let Syncro auto-calc from the product rate" was wrong — the rate does NOT populate automatically.

+**Emergency / after-hours billing branches by whether customer has prepaid labor:**
+
+Check: `GET /customers/<id>` → `.customer.prepay_hours` (string; `"0.0"` means no prepaid, any non-zero means prepaid block exists).
+
+| `prepay_hours` | Regular hours | Emergency / after-hours |
+|---|---|---|
+| `0` / null (no prepaid) | `26118`, qty = actual_hours | `26184`, qty = actual_hours (rate already 1.5×) |
+| `> 0` (has prepaid block) | `26118`, qty = actual_hours | `26118`, qty = actual_hours × **1.5** |
+
+**Rationale (Winter, 2026-04-23):** Prepaid blocks debit by QUANTITY, not dollars. To charge time-and-a-half against a prepaid block we bump the quantity to 1.5× on the Onsite product rather than switching to the Emergency product — switching would double-count because the Emergency product has the 1.5× already built into its dollar rate.
+
+**Example — 2 hour emergency onsite job:**
+- Non-prepaid customer: one line of 2.0 hrs × `26184` → $525.00 billed
+- Prepaid customer: one line of 3.0 hrs × `26118` → debits 3 hrs from the prepaid block ($525.00 equivalent, drawn from prepay)
+
+Winter caught this on #32203 (Desert Auto Tech) 2026-04-23 after I stacked 1hr `26118` + 1hr `26184` for a single hour of emergency work — the $ doubled because the 1.5× was applied twice.

+name: Syncro emergency/after-hours billing — check prepay_hours first
+description: Emergency labor is 1.5× multiplier, not additive. Branch by customer.prepay_hours — wrong branch doubles or undercharges. Applies to every /syncro bill for emergency work.
+type: feedback
+---
+
+**Rule:** Before adding any Emergency/after-hours labor line item on a Syncro ticket, `GET /customers/<id>` and read `prepay_hours`.
+
+- If `prepay_hours == 0` (no prepaid block): use product `26184` (Labor - Emergency/After Hours) at quantity = actual hours. The $262.50/hr rate already has the 1.5× multiplier baked in.
+- If `prepay_hours > 0` (customer has a prepaid block): use product `26118` (Labor - Onsite) at quantity = actual hours × 1.5. Prepaid blocks debit by QUANTITY, not dollars, so we bump qty instead of swapping to the Emergency product.
+
+Never stack `26118` + `26184` for the same hour of work. Pick one path based on the prepaid state.
+
+**Why:** Learned on ticket #32203 (Desert Auto Tech) 2026-04-23. Howard asked to bill "1 hour onsite + 1 hour emergency onsite." I posted both as separate additive line items and the invoice came out at $437.50 when the correct bill for 1 actual hour of emergency work was $262.50. Winter caught it and explained the rule: "the goal is to have it bill at time and a half." The Emergency product = time-and-a-half by rate; prepaid accounts = time-and-a-half by quantity. Swapping products AND multiplying quantity double-counts.
+
+**How to apply:**
+- Every `/syncro bill` for emergency/after-hours work: check `prepay_hours` BEFORE choosing the product. Do not shortcut this.
+- For a 2-hour emergency job:
+  - Non-prepaid customer → one line, 2.0 hrs × `26184` → $525.00
+  - Prepaid customer → one line, 3.0 hrs × `26118` → 3 hours debit from block
+- Always set `price_retail` explicitly on `add_line_item`. The old "omit and let Syncro auto-calc" guidance was wrong — the rate does not populate from the product config, and the invoice will post at $0 if `price_retail` is missing. Fetch the current rate with `GET /products/<id>`.
+- Never let a customer-facing invoice post without verifying `.invoice.total` matches the expected `qty × price_retail`.
