Which documents and obligations are covered?

Quotes, proformas, delivery notes, recurring invoices, sales invoices and purchase invoices share one flow. You also get VeriFactu, Facturae with FACe tracking and drafts for forms 303, 130 and 347, plus payments, stock and reports.

Can I test automations without touching real data?

Yes. Test keys work with an isolated company through the same API. You can issue, correct and test flows without sending anything to the tax office, by email or to other services, and without touching your real series. Once everything is validated, you change the key.

How do I continue my current numbering?

Create the series with the next number you need. The number is assigned when you issue, not when you open the form, so a discarded draft uses no number. After the first issue, the series continues consecutively with no gaps.

How do I connect Factuarea to my systems and assistants?

The API, MCP server, webhooks and workflows connect clients, items, documents and payments to your tools. You can query data from a compatible assistant, react to events and automate tasks without duplicating information.

Invoicing comparison

Do not compare an entire ERP. Compare the work of invoicing.

Factuarea concentrates the complete invoicing flow in an experience that is ready to use. In Odoo, these tasks are spread across apps, setup and, in several cases, the Custom plan.

Sales and purchase documents

The complete document flow is ready in one app: quotes, proformas, delivery notes, invoices, recurring invoices and purchase invoices.

In Odoo

The cycle is distributed across the Invoicing, Sales, Purchase and Inventory apps. Each company has to install and coordinate the ones it needs.

AI inside the software

Operational AI inside everyday work. It creates clients, prepares documents, writes descriptions and solves software questions in natural language.

In Odoo

Odoo 19 includes Ask AI. The standard agent does not change data. Taking actions requires installing and configuring the AI app, topics and tools.

WhatsApp connected to data

The Factuarea bot understands questions about your business, checks invoicing and prepares tasks using real account data.

In Odoo

The WhatsApp app is exclusive to Odoo Enterprise and requires WhatsApp Business Platform setup in Meta. Its official use is client messaging and templates, not querying invoicing through conversation.

MCP and API

A dedicated MCP server for connecting your assistants and an API prepared to integrate Factuarea with any system.

In Odoo

The external API is not included in the Standard plan. Odoo reserves it for the Custom plan, which costs almost twice as much per user on its published annual pricing.

Automation

Workflows, webhooks, recurring invoices and templated emails are already designed around the invoicing flow.

In Odoo

Webhooks and customisation with Studio require the Custom plan. Activating Studio from Standard changes the subscription automatically.

Compliance and tax

VeriFactu, Facturae with direct FACe submission and drafts of forms 303, 130 and 347 inside the same flow.

In Odoo

It requires installing the Spanish localisation modules and configuring certificates. For Facturae it generates the XML, but submission to FACe is manual.

Payments and client communication

You send a public link, the client pays with Stripe and the invoice is marked as paid automatically. Documents and emails are customised in the same flow.

In Odoo

Stripe, online payments and subscriptions require enabling and configuring the corresponding apps and providers.

Stock, reports and teams

Stock, reports, analytics, accountant access, users and time tracking all work with the same invoicing data.

In Odoo

Accounting, CRM, manufacturing, projects and inventory live in separate apps. If invoicing is all you need, they add setup and workspace surface.

AI connected to your invoicing

Three ways in. The same data and the same work.

Talk to Factuarea inside the app, through WhatsApp, or from ChatGPT, Claude and other assistants via MCP. This is not an isolated chat: it reads your data and prepares work that continues in the application.

Your preferred assistant

Connect the MCP server and use Factuarea functions from a compatible client, with precise permissions for each operation.
