# Project Fixed Price + Milestone Invoicing
The project and customer PRE-EXIST. Search — NEVER create. **5 calls, 3 writes, 0 errors.**
## Call 1: Find Project + Find Bank Account (2 GETs — free, parallel)
```
GET /project?name=<project_name>&fields=id,name,customer(id)&count=5
GET /ledger/account?number=1920&fields=id,number,bankAccountNumber,isBankAccount
```
From project: extract `project.id` and `project.customer.id`.
From account: extract the account `id` for account 1920.
## Call 2: Update Project + Set Bank Account (2 WRITEs — parallel)
Calculate milestone_amount = percentage × fixedprice (e.g. 50% × 342600 = 171300).
```json
PUT /project/<project_id>
{
"id": <project_id>,
"name": "<project name>",
"isFixedPrice": true,
"fixedprice": <total_fixed_price>,
"invoiceOnAccountVatHigh": true
}
```
```json
PUT /ledger/account/<account_id>
{
"id": <account_id>,
"name": "Bankinnskudd",
"number": 1920,
"bankAccountNumber": "86011117947",
"isBankAccount": true
}
```
## Call 3: Create Invoice (1 WRITE)
```json
POST /invoice
{
"invoiceDate": "<today>",
"invoiceDueDate": "<today + 14 days>",
"orders": [{
"customer": {"id": <customer_id>},
"project": {"id": <project_id>},
"orderDate": "<today>",
"deliveryDate": "<today>",
"invoiceOnAccountVatHigh": true,
"orderLines": [{
"description": "Milestone <percentage>%",
"unitPriceExcludingVatCurrency": <milestone_amount>,
"vatType": {"id": 3},
"count": 1
}]
}]
}
```
**Total: 5 calls (2 GETs free + 3 writes), 0 errors. Done.**
## STRICT RULES
- **Project PRE-EXISTS** — search by name, NEVER create a new project
- `invoiceOnAccountVatHigh: true` on BOTH the project PUT AND the inline order
- milestone_amount = percentage × fixedprice from the prompt
- vatType `{"id": 3}` = output VAT 25% — REQUIRED on order lines
- Bank number is EXACTLY `86011117947` — do NOT use any other number
- Do NOT call PUT /:send — prompt never asks to send the invoice
- Use today's date for all date fields
- After the POST /invoice succeeds, STOP. Do not make any more calls.
