Invoicing that speaks Spanish tax.
GrowthInvoices runs your billing inside WordPress — clients, quotes, invoices, payments and tax reports. Multiple VAT rates, optional IRPF and a VeriFactu-ready core, with no monthly cloud fees.
Everything you need to invoice
Invoices done right
Issue with gap-free, correlative numbering per series and year. Once issued an invoice is locked; corrections use a rectificative.
Quotes that close
Full lifecycle from draft to sent to accepted, and one-click convert to invoice.
Spanish taxes, built in
Multiple VAT rates per line, optional IRPF withholding and equivalence surcharge, with the correct per-rate breakdown.
Payments & due dates
Record full or partial payments; the status reconciles automatically from issued to partial to paid.
Reports that file themselves
Quarterly VAT/IRPF summary aligned with models 303 and 130/111, plus VAT broken down by rate.

Drop the [growthinvoices_app] shortcode on a private page and run everything without wp-admin.
