The real comparison is workflow coverage
Most WooCommerce invoice plugin comparisons stop at PDF templates and email attachments. Those matter, but they do not answer the expensive questions: can finance trust the invoice number sequence, can B2B VAT evidence survive refunds, and can customers download the same document your accountant exports?
Lattice Invoices is positioned around those workflow gaps. The early-access review turns your current stack into a concrete buying decision: keep your current PDF plugin, add VAT workflow support, or move toward the Lattice Invoices product path.
Plugin option comparison
| Option | Strengths | Common gaps | Best fit |
|---|---|---|---|
| Generic PDF invoice plugin | Fast PDF generation, email attachments, basic invoice templates, often inexpensive. | Usually weak on EU B2B VAT fields, reverse-charge evidence, credit-note workflows, and accountant exports. | Small domestic B2C stores with simple paid-at-checkout orders. |
| VAT field / tax add-on | Captures VAT IDs, company fields, exemption rules, and tax validation metadata. | Does not always own invoice numbering, PDF delivery, credit notes, or reconciliation after payment. | Stores that already have invoice PDFs but need cleaner B2B VAT data at checkout. |
| Accounting connector | Syncs orders, payments, taxes, and customers into bookkeeping software. | May export WooCommerce order data rather than a controlled invoice record customers can download and audit. | Stores where the accountant already lives in one accounting platform and invoice PDFs are solved elsewhere. |
| Lattice Invoices early access | Focused EU VAT workflow: sequential invoice numbers, PDF delivery, credit notes, reverse charge, BACS/proforma, audit trail, reconciliation, and accountant handoff. | Early-access product path; best for stores willing to share their real invoice workflow before the final release. | EU WooCommerce stores that sell B2B, use bank transfer, handle refunds, or need invoice evidence finance can trust. |

Buyer scenarios that expose weak invoice plugins
You sell B2B across EU borders
Need: VAT ID capture, country evidence, reverse-charge wording, and a PDF that proves why VAT was not charged.
Test before buying: Place a test B2B order with a company VAT number and verify the invoice, order metadata, and export all agree.
You accept bank transfer / invoice-me orders
Need: A proforma or payment request before money arrives, then a final paid invoice after reconciliation.
Test before buying: Create a BACS order, mark it paid later, and confirm the final invoice date/payment status are correct.
You process partial refunds
Need: Linked credit notes with their own numbers, VAT correction totals, and visible reference to the original invoice.
Test before buying: Refund one line item and confirm the original invoice is preserved while the credit note is created separately.
Your accountant asks for month-end evidence
Need: A clean export containing invoice status, paid status, VAT treatment, credit notes, and PDF links.
Test before buying: Export a mixed month of paid, unpaid, B2B, refund, and bank-transfer orders and check if it closes without spreadsheets.

What is the best WooCommerce invoice plugin for EU VAT stores?
The best choice depends on your workflow. A simple PDF plugin can work for domestic B2C orders, but EU B2B stores should compare VAT fields, reverse-charge wording, sequential invoice numbers, credit notes, customer downloads, and accounting export before buying.
Should I buy a PDF invoice plugin or a VAT plugin first?
If the invoice PDF is missing, PDF delivery is urgent. If your PDFs already exist but contain weak VAT evidence, the checkout VAT workflow may be the bottleneck. For EU B2B stores the two need to work together, not as disconnected plugins.
Why are WooCommerce order IDs not enough for invoices?
Order IDs can include gaps, cancelled tests, drafts, failed checkouts, and unrelated records. Finance teams often need a controlled invoice-number sequence and a separate credit-note sequence that maps to issued documents.
