Switching from SkyVerge Print Invoices and Packing Lists to invoice9
SkyVerge's plugin ships generic PDF invoices but no structured e-invoice formats — meaning German Jan 2027 and French Sep 2026 mandate compliance is outside its scope. invoice9 ships all four EU country formats at $29/year less.
SkyVerge's Print Invoices and Packing Lists is one of the oldest and most-installed plugins on the Woo Marketplace — 10K+ paying sites, 4.0★ across 41 reviews, consistent vendor support. If you landed on it years ago for basic invoices and packing slips, it still does that job.
What it doesn't do: generate the structured e-invoice formats that the EU 2026-2028 mandate wave requires.
What SkyVerge ships vs. what the mandate needs
SkyVerge's plugin generates a PDF invoice. The PDF is human-readable and contains your store's data. That's it.
What the German Jan 2027 mandate requires: a hybrid PDF/A-3
(archival profile) with an embedded EN 16931-compliant CII XML
attachment named factur-x.xml. The recipient's accounting system
(DATEV, lexoffice, sevDesk) parses the XML directly — no manual data
entry. SkyVerge's plugin doesn't generate this.
The same applies to:
- France's Sep 2026 Factur-X mandate — same hybrid PDF/A-3 structure, French CIUS rules
- Germany's XRechnung B2G — pure XML, used for sales to federal/state agencies; SkyVerge generates PDF only
- Belgium's PEPPOL B2B mandate (live since Jan 2026) — UBL XML routed through PEPPOL Access Points
If you sell B2B in mandate-affected countries, SkyVerge will not get you to compliance. That's the structural mismatch.
Where SkyVerge is genuinely better than invoice9
- Packing slips and pick lists — SkyVerge has a deeper document suite for warehouse fulfillment. invoice9 doesn't ship these at v1.
- Live preview customizer — SkyVerge integrated with the WordPress Customizer for visual invoice tweaking. invoice9's v1 ships locale-default templates only.
- 10K+ active installs and 4.0★ — they have a track record. We're new.
If invoices are simple and EU mandates don't apply to your store, SkyVerge is fine. invoice9 is for the case where mandates do apply.
The migration
invoice9 detects SkyVerge on activation. Because their settings live in WooCommerce's email settings (per-email attachment) rather than their own dedicated option keys, we don't auto-copy — but the manual migration is short.
- Install invoice9 from the WooCommerce Marketplace.
- Configure your seller info under WooCommerce → Settings → invoice9.
- Disable SkyVerge's per-email invoice attachment under WooCommerce → Settings → Emails → Customer Completed Order → "Attach invoice from SkyVerge" (toggle off).
- Set invoice9's default format to Auto.
- Generate a test invoice from a recent completed order. Verify the ZUGFeRD or Factur-X output.
- You're live. SkyVerge stays installed for packing slips if you want it; invoice email attachment now flows through invoice9.
Why $50/year vs SkyVerge's $79/year
invoice9 is a newer entrant playing on volume rather than premium positioning. The $29/year savings compound: over a 5-year horizon, that's $145 per site. If you're on the WP-Overnight reasoning ("paying for product that updates frequently"), SkyVerge does update — but the updates don't include EU mandate formats, so the extra $29/year goes to features outside invoice9's scope.
Frequently asked questions
Does invoice9 do packing slips?
Not at v1. We focus on invoices and credit notes. If packing slips are part of your fulfillment workflow, run SkyVerge alongside invoice9 — they coexist as long as only invoice9 handles invoice email attachment.
What about my existing PDF invoices from SkyVerge?
They stay where they are — SkyVerge stores them on demand, not as persistent files. invoice9 generates PDFs for new orders going forward; old SkyVerge PDFs can still be regenerated through the SkyVerge admin.
Is SkyVerge's email-attachment toggle in their settings or in WC's email settings?
It's per WC email type, controlled inside the WC Emails settings (not under SkyVerge's own settings). Look at the bottom of each email's settings page for the SkyVerge-injected attachment toggle.
Can I keep using SkyVerge's invoice template customization?
SkyVerge's template customizer doesn't transfer to invoice9. invoice9 ships locale-default templates focused on compliance. If template customization is critical, keep SkyVerge for that and use invoice9 for the structured-format generation.
