Agency invoice workflow

WooCommerce invoice plugin checklist for agencies managing EU client stores.

If you build WooCommerce stores for EU clients, invoice setup should be a repeatable launch workflow — not a custom rescue job after the first B2B customer asks for a corrected VAT invoice.

The agency problem: invoice support does not end at launch

Most WooCommerce builds test checkout, shipping, and confirmation emails. EU B2B invoice requirements often get discovered later: missing VAT fields, incorrect invoice numbers, no customer download area, or refunds without credit notes.

That creates low-margin support work for agencies. A reusable invoice workflow lets the agency sell a cleaner handoff: B2B checkout fields, invoice PDFs, credit notes, customer downloads, and accountant-ready order evidence.

Signals that your client needs an invoice workflow

→Every client has a slightly different VAT/BTW checkout-field request
→Invoice PDF plugins get configured differently per build and become hard to support
→Clients ask for missing invoices, resend buttons, credit notes, and accountant exports after launch
→B2B customers need VAT IDs, PO references, invoice email fields, and reverse-charge wording
→Support time grows when invoice numbers, refunds, and PDF delivery are not standardized

Repeatable process

A better agency handoff for WooCommerce invoices

Discovery

Ask whether the store sells B2B, B2C, subscriptions, digital products, bank-transfer orders, or cross-border EU orders before selecting invoice settings.

Checkout fields

Standardize company name, VAT/BTW number, invoice email, PO reference, and optional buyer notes so client data is captured before payment.

Invoice trigger

Decide whether final invoices are issued on processing, completed, or paid status. Keep proforma and final invoice timing separate for bank-transfer clients.

Refund path

Create credit notes from refunds instead of editing old invoice PDFs. Keep the original invoice number visible in the audit trail.

Handoff

Document invoice-number format, VAT evidence fields, PDF email attachments, customer downloads, and accountant export expectations before launch.

Agency launch QA checklist

✓Place a test B2B order with company name, VAT/BTW number, invoice email, and PO reference
✓Confirm the processing/completed order email contains the right PDF invoice attachment
✓Open My Account as the customer and verify the invoice download is visible and private
✓Refund the test order and verify the credit note has its own number and references the original invoice
✓Export or inspect order metadata for invoice number, invoice date, VAT number, VAT amount, and country
✓Document the exact invoice-number format and trigger for the client handoff notes

FAQ for agencies

Why should agencies care about invoice workflows before checkout goes live?

Because payment success is not the end of a B2B order. Clients still need VAT evidence, invoice PDFs, customer downloads, refund documents, and support-ready resend workflows after launch.

Is this only for Dutch agencies?

No. The checklist is useful for any agency building EU WooCommerce stores, but it explicitly includes Dutch BTW language because many Dutch webshops search for BTW factuur plugin solutions.

Can agencies use Lattice Invoices for multiple clients?

The early-access path is intended to qualify real store workflows first. Agencies should send the number of WooCommerce client stores, countries, VAT requirements, and whether a repeatable agency license is needed.

What is the fastest way to qualify a client?

Send the client store URL, country, B2B/B2C mix, payment methods, invoice-number format, VAT fields, and whether credit notes and accountant exports are required.
