この製品について
Many tax authorities require invoices to carry a strictly sequential, gap-free number within a defined scope — usually per calendar year, and often per country or per legal entity. WooCommerce core does not provide this. Out of the box it exposes only the internal order ID (which skips numbers because draft, failed, and trashed orders consume IDs), and that is not a compliant invoice number in jurisdictions like the EU, GCC, LATAM, and many others.
Sequential & Per-Country Invoice Numbering for WooCommerce is a plugin ECOSIRE builds, installs, and supports on your WordPress site. It is not an instant marketplace download — we scope your exact numbering rules, build the plugin against your store, deploy it, and back it with support.
The plugin assigns a real invoice number at a deterministic point in the order lifecycle (typically on the woocommerce_order_status_processing / _completed transition, or on payment capture — your choice). Numbers are allocated using a row-locked counter in a custom table so two simultaneous checkouts can never collide or skip, even under load. It is fully HPOS-compatible (WooCommerce High-Performance Order Storage / custom order tables) and falls back cleanly to legacy post-meta storage.
You define the scope of each sequence: a single global run, one per year, one per store/legal entity, or one per billing country / tax jurisdiction. Each sequence gets its own configurable prefix, suffix, zero-padding, and start value, and its own reset rule (yearly, monthly, or never). Credit notes and proforma invoices run on separate, independent sequences as auditors expect. Everything is exposed through wp-admin settings, WordPress hooks/filters for your developers, and read access via the WooCommerce REST API.

これは誰のためのものですか
EU / GCC compliance-bound merchant
Operates in a jurisdiction that legally mandates gap-free, per-year invoice numbering (e.g. for VAT or e-invoicing) and needs WooCommerce to produce numbers an auditor will accept — something core cannot do.
Multi-country store operator
Sells across several countries or legal entities from one WooCommerce install and must issue distinct numbering sequences per jurisdiction, each with its own prefix and yearly reset.
Accountant or finance lead
Reconciles WooCommerce orders against bookkeeping and needs invoice numbers that are continuous, predictable, and separated correctly for credit notes and proforma documents.

Sequential & Per-Country Invoice Numbering に関するよくある質問
How long does it take to build and install?
Because this is built to your exact jurisdiction and entity rules, typical delivery is about one working week from when we confirm your numbering requirements, formats, reset rules, and WooCommerce/HPOS setup. We share the timeline in writing before starting. Backfilling historical orders, if requested, is scoped and scheduled separately so it never disturbs your live counters.
Do I get ongoing support and updates?
Yes. Every build includes a post-deployment support window for bug fixes and compatibility with WooCommerce and WordPress updates, including HPOS changes. After that window we offer ongoing support and maintenance so your numbering stays compliant as your store, tax rules, or WooCommerce version evolve. We do not push silent auto-updates to your live site — changes are reviewed and deployed deliberately.
Will this work with HPOS (High-Performance Order Storage)?
Yes. The plugin is built to be HPOS-compatible and reads and writes the invoice number on the custom order tables when HPOS is enabled, with a clean fallback to legacy post-meta when it is not. We verify this against your specific WooCommerce version and active payment gateways as part of the build.
Can WooCommerce not just use the order ID as the invoice number?
No, and that is exactly the problem this solves. The WooCommerce order ID skips values because draft, failed, abandoned, and trashed orders all consume IDs, so the sequence has gaps. Most tax authorities reject gapped numbering. This plugin allocates a separate, genuinely gap-free invoice number from a locked counter at a controlled point in the order lifecycle.
Can I have different sequences and prefixes per country or per year?
Yes. You define the scope of each sequence — global, per year, per store or legal entity, or per billing country — and each one has its own prefix, suffix, zero-padding, start value, and reset rule. Credit notes and proforma invoices run on their own independent sequences. We configure these to match what your accountant or local regulations require.
