Frequently asked questions about FIZ for companies

What does FIZ do, and what does the accountant do?

FIZ Max collects documents, matches payments, applies your category rules and prepares the IVA declaration. Your certified accountant remains responsible for the company’s accounts, in the software they already use, with the data FIZ gives them.

What is the difference between Pro and Max?

Pro is for invoicing and getting paid: unlimited invoicing, templates, scheduled invoices, WhatsApp and API, access permissions, and payments by card on your phone, QR code and link.

Max includes everything in Pro and adds the IVA declarations, invoice and transaction import, data for your accountant, payment tracking, categories and rules, and the lowest fee per payment.

During the 14 free days and on Pro, the FIZ AI advisor answers 10 questions per account in total, not per month. On Max, paid or with free months earned through invitations, it answers unlimited questions.

How do bank transactions get into FIZ?

In FIZ Max, there are two ways: a bank connection brings them in automatically, or you import a bank statement whenever you like.

How do foreign supplier invoices get into FIZ?

In FIZ Max, forward them by email or upload them, including invoices from Google Ads, Meta and Adobe: FIZ reads the data and adds them to your other expenses. For these services, your company declares the IVA (autoliquidação): FIZ includes it in the periodic declaration and, with a full deduction, the balance is 0 €.

How do categories link to the SNC chart of accounts?

In FIZ Max, you choose simple categories such as product sales, consultancy or rent, and FIZ automatically links each one to its SNC account, the accounting standards system used by Portuguese companies.

Can I correct a category or match?

Yes. You can change any category or match that FIZ suggests. A rule applies the same category to similar future transactions.

How do I see what customers owe me and what I owe suppliers?

In FIZ Max, open the customer or supplier record to see invoices, linked payments and the amounts still to receive or pay.

How is the company’s IVA declaration submitted?

In FIZ Max, FIZ prepares the periodic declaration and, if the company sells goods or services to businesses in other EU countries, the recapitulative one. Your certified accountant looks over the data and confirms with one click, and FIZ submits them to AT. The submission result and the IVA payment document then appear in FIZ.

IVA declaration for companies
How do I share data with my accountant?

Invite your accountant to FIZ. In FIZ Max, you can also export journal entries in Excel for TOConline, Cegid Business, iziBizi or Sage, or as CSV.

Where are invoices and documents stored?

Invoices you issue in FIZ are stored in the FIZ digital archive, ready to view. In FIZ Max, the archive also holds copies of received invoices that you upload or forward, and you can export it for any period and send it to your accountant.

Can I assign access permissions to my team and accountant?

Yes. Invite employees and your accountant to FIZ and choose each person’s access permissions.

How does the discount on paid plans work?

The price shown already includes the discount; when it ends, the regular price applies, also shown on the plan.
