Can I keep my numbering?

Yes. When you create the series you say which number you want to start at, and the count carries on from there. You choose the letters at the front, whether the year shows up, and how many leading zeros the number has.

Can I try Factuarea while I keep using Factusol?

Yes. The trial runs in a separate account and does not change anything in Factusol. You can test the workflow with sample data and, once you decide, import your customers, products and issued invoices.

And if one day I have no internet?

You need a connection to issue. Use local Wi-Fi or mobile data and keep working from your computer, tablet or phone.

What does it cost, and what if it is not for me?

Ten days to try it without entering a card. After that it is €9.90 a month, or €6.90 a month if you pay for the year. The team plan is €24.90 a month, or €18.90 paying yearly. There is no permanently free plan. If you leave, you take your data with you.

Factuarea versus Factusol

From managing invoices to a platform that works with you.

Factuarea brings together documents, stock, compliance and reports, then adds in-app AI, a WhatsApp bot connected to your data, MCP, API, workflows, webhooks and online payments in the same flow.

Invoicing comparison

Traditional invoicing has plenty of overlap. The difference is what comes next.

FACTUSOL covers a broad commercial cycle. We compare that foundation and the connected work that saves time today: talking to data, automating and integrating.

Sales and purchase documents

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

In Factusol

It also covers quotes, orders, delivery notes, invoices, purchases and recurring billing.

AI inside the software

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

In Factusol

The official page reviewed does not present a built-in conversational assistant for creating or managing invoicing in natural language.

WhatsApp connected to data

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

In Factusol

It can send documents through WhatsApp. It does not present the channel as an agent that queries and acts on account data.

MCP and API

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

In Factusol

It publishes an API for its cloud products aimed at integrations. It does not publish an MCP server.

Automation

Workflows, webhooks, recurring invoices and templated emails are already connected to the invoicing flow.

In Factusol

It includes recurring billing and administrative utilities. Automation follows a more traditional business-software approach.

Compliance and tax

VeriFactu, Facturae with FACe and drafts of forms 303, 130 and 347 inside the same flow prepared for Spain.

In Factusol

It is also adapted to VeriFactu and Facturae, along with other Spanish schemes and obligations.

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 Factusol

It manages collections, receipts, direct debits and, in the cloud, bank reconciliation. It also sends documents by email or WhatsApp.

Stock, reports and teams

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

In Factusol

It stands out for advanced stock and custom reports and includes employee records in its commercial management.

What happens to earlier invoices

Old invoices come in as history. They keep their date and number and are not sent to the tax authority again. New invoices issued in Factuarea generate the VeriFactu record.

Questions

What everybody asks before switching

Both cover documents, stock, payments and compliance. Factuarea stands apart through AI working inside the app, a WhatsApp bot connected to your data, MCP for your assistants, API, workflows, webhooks and online payments integrated into the flow. It also opens in the browser with nothing to install.
