After InvoiceIngestWorker writes cost lines and matches resources, it
pushes a normalized invoice payload to skyai-finance-svc's new endpoint
POST /api/v1/integrations/cloud/import-invoice. Idempotent — finance
dedups on (tenant_id, source, external_id), so re-runs return "updated"
not duplicate rows.
ArcadiaCloud.Integrations.SkyaiFinance is the HTTP client. Auth is a
short-lived JWT minted via Guardian (shared secret per memory) with
identity {tenant_id: "platform-admin", roles: ["admin"]} — the role
satisfies finance's RequireWriteRole plug. Identity + base URL are
configurable; SKYAI_FINANCE_URL env var can override the default
http://localhost:4010 for arcadia-dev / prod.
GST line detection: lines whose description contains "gst" or "tax"
get summed into amount_tax_minor; everything else into amount_net_minor;
sum stays gross. Phase 1 enough — proper tax handling lands when
real per-tenant invoices flow.
cloud_invoices gains pushed_to_finance_at + finance_invoice_id so we
don't re-push uselessly (Billing.mark_invoice_pushed/2 records both).
A missing finance config (no :skyai_finance app env) makes the push a
silent skip rather than a worker failure — environments without finance
configured still get a working ingest.
Live verified end-to-end against both services:
- April 2026 DO invoice (33 lines, $86.92) lands in finance as a row
with gross=$86.92, tax=$7.90, source=digitalocean, tenant=platform-admin
- DigitalOcean vendor auto-created (category=cloud) under platform-admin
- Re-running the worker returns action: "updated" not "created";
finance still has exactly 1 row for the invoice

Three new schemas:
- cloud_balance_snapshots — hourly MTD balance/usage poll for live-accrual.
- cloud_invoices — header per provider invoice, with ingest status flags.
- cloud_cost_lines — per-line-item COGS, FK to cloud_resources where matched.
Three new Oban workers (queue: cloud_billing):
- BalanceWorker (hourly) records a snapshot.
- BillingHistoryWorker (daily) discovers invoices via /v2/customers/my/
billing_history, upserts headers, enqueues an InvoiceIngestWorker for
each not-yet-ingested invoice.
- InvoiceIngestWorker (per-invoice) fetches /invoices/:uuid/csv, parses
with NimbleCSV (header-keyed so column order shifts don't break us),
replaces the invoice's line set, then matches lines to cloud_resources
by (kind, name) — case-insensitive, name extracted from "name (size)"
description format.
DigitalOcean.Client gains get_balance / list_billing_history /
get_invoice_summary / fetch_invoice_csv. The CSV endpoint returns text/csv
so we bypass Req's body decoder.
Cron additions: BalanceWorker hourly at :07, BillingHistoryWorker daily
at 02:23.
API:
- GET /api/v1/billing/balance — latest snapshot, platform_admin only.
- GET /api/v1/billing/cost-lines?period=YYYY-MM-DD&kind&limit — per-line
COGS, platform_admin only.
Live smoke against real DO billing API surfaced and fixed three CSV-format
gotchas: column headers use underscores not spaces (group_description,
project_name), USD column has $ prefix, dates use "YYYY-MM-DD HH:MM:SS
+0000" format (space separator + RFC822 offset).
Verified: 137 historical invoices discovered going back to 2014;
April 2026 invoice (33 lines, $86.92 total) ingested with 6/33 lines
matched to current cloud_resources. Unmatched lines are correctly
historic droplets, Spaces buckets (not yet synced), and GST.
NimbleCSV ~> 1.2 added as a dep.
