InvoiceXpress review
Low-cost Portuguese e-invoicing with recurring billing, reminders, payments, and exports.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
InvoiceXpress is cloud-based invoicing software for freelancers, service businesses, independent professionals, and online stores. It supports invoices, receipts, quotes, credit and debit notes, customer balances, reporting, payment collection, and document delivery across web, iOS, and Android. Portuguese businesses are the clearest fit because the service is certified by Portugal’s Tax Authority and supports digitally signed electronic invoices and SAF-T PT exports.
Pricing is organized around monthly document volume. X3 costs €3 per month for 3 documents, while X10 costs €9 for 10, X20 costs €14 for 20, and X30 costs €18 for 30. X100 costs €24 for 100 documents, and X500 costs €29 for 500. The plans include unlimited users, with API access on X3 through X30 and invoice scheduling, multi-currency documents, and collection alerts across the listed tiers. X100 adds an online current account, while X500 adds reports. The pricing page states that VAT is additional. InvoiceXpress also offers a free plan and a 30-day full trial.
For recurring billing, the product can schedule invoices and automatically email generated documents. Payment and expiration alerts can be sent by email or SMS, while customers can pay by credit card or use Multibanco references. Integrations include WooCommerce, Shopify, the API, and InvoiceXpress MCP, which provides AI-assisted invoicing. Data can be exported in SAF-T PT, Excel, CSV, and XML formats. InvoiceXpress suits Portuguese teams that need localized compliance, payment workflows, and modest-to-high document volumes without per-user pricing. Businesses needing document volume above 500 per month, or a broader integration ecosystem than the listed options, should compare alternatives.
