Auto invoices after payment
why auto invoices after payment breaks without automation
Accounts re-key paid orders into the invoicing tool or ERP. Delays hurt B2B buyers who expect instant documents and flood support with “where is my invoice” tickets in peak season. Do not ship a monolith script: split validation, idempotent write and alerting so correlation ids survive across retries. For auto invoices after payment, ops time disappears into retyping between WooCommerce, Fakturownia / wFirma, Comarch Optima. Without a queue the first API timeout leaves systems out of sync. WooCommerce webhooks, n8n, REST work when rules are deterministic and can be rehearsed on staging with redacted production payloads. Keep PII out of debug logs and sign a processing agreement with whoever hosts the workflow. Canonical records usually sit in the ERP or HRIS; the shop or form layer only emits events. Action Scheduler or n8n owns retries with backoff so partner APIs are not stampeded. Pager alerts go to Slack or Teams with the payload id and idempotency key.

how to implement auto invoices after payment step by step
- Confirm the order has a unique number and no linked invoice yet. Persist a correlation run_id for auto-invoices-after-payment before calling WooCommerce. [auto-invoices-after-payment:step1]
- Map line items, tax ID, VAT rate and currency into the invoicing document. Validate the JSON schema in WooCommerce webhooks and reject payloads missing required keys. [auto-invoices-after-payment:step2]
- Issue the invoice, fetch the PDF and attach it to the transactional email. On success update remote meta or status so a replayed webhook cannot duplicate. [auto-invoices-after-payment:step3]
- Store the external invoice ID on order meta and sync it to the ERP. Pager alerts go to Slack or Teams with the payload id and idempotency key. Include a short hash of the last API error. [auto-invoices-after-payment:step4]
- On tax-ID validation failure, hold the send and flag the order for data fix. Persist a correlation run_id for auto-invoices-after-payment before calling WooCommerce. [auto-invoices-after-payment:step5]

how data moves in auto invoices after payment
An `order.paid` webhook hits n8n, which calls the invoicing API and optionally the ERP. The PDF returns to WooCommerce as an attachment; WP-Cron replays missed gateway webhooks from the log. Field mapping must cover currency, time zones and intermediate statuses that are unique to auto invoices after payment, or month-end reports will disagree with finance.
