About

We know how invoicing can be a headache. That's why we help entrepreneurs change to the simple side of invoicing. InvoiceXpress is an online invoicing software approved by the Portuguese Tax and Customs Authority, which you can have access to from anywhere. Using InvoiceXpress doesn't make you attached to it. Use it whenever you need to issue documents and change your plan according to your invoicing. Aimed at companies that provide all sorts of services, InvoiceXpress also suits freelancers, self-employed professionals and online stores. Add invoicing to your business through our API or plugins. Direct communication with the Taxing Authority. Proceed immediately to create the invoice. Once it is finished, it's valid and ready to send.

About

Melso is an online accounting and tax service for freelancers and self-employed people in Spain, combining an AI agent, web-based tax tools and human tax professionals. It helps users organize invoices and expenses, review income and costs, follow a tax calendar, and get answers about Spanish tax procedures through the app or WhatsApp. Users can connect email and Google Drive to find records, and authorize compatible AI clients through OAuth and Model Context Protocol (MCP) to access business records and prepare work. Melso’s professionals prepare and review returns included for each customer’s activity and tax profile. Customers approve the exact draft in the app before the professionals file it with Spain’s tax agency; covered forms and services depend on the agreed scope. The AI agent can draft invoices and issue them after customer authorization, subject to account permissions and service prerequisites.
