Create invoices for woocommerce multicurrency stores

Create sequentially numbered PDF invoices from the incoming orders on 3 multicurrency woocommerce stores.

- The invoices have to be generated in a single number sequence.
- Generate invoices in EUR only, so amounts in currencies other than EUR have to be converted to EUR.
- Possibility to manually inject invoices at any given time, using an address book to be able to reuse customer details.

Example:
Order 1, Website 1, : 25.95 GBP => Invoice # 0001, 29,95 EUR
Order 2, Website 3, : 39.95 USD => Invoice # 0002, 34,95 EUR
Order 3, Website 1, : 25.95 GBP => Invoice # 0003, 29,95 EUR
Order 4, Website 2, : 730 MXN => Invoice # 0004, 29,95 EUR
Order 5, Manually injected, invoice # 0005, 29,95 EUR
Order 6, Website 2, : 730 MXN => Invoice # 0006, 29,95 EUR
etc.

If the solution requires Zapier and apps like QuickBooks Online or InvoiceNinja the project includes setting up the required accounts to produce the desired result.
