Moloni vs Faturiza: When It Makes Sense to Switch (and When It Doesn't)

The Moloni vs Faturiza question comes up often — and most accountants asking it aren't actually thinking about switching. They're trying to solve a problem Moloni was never built for in the first place.

Moloni is a billing system. It exists to help you issue invoices that are certified by the Autoridade Tributária. It does that job well. What it doesn't do — and was never designed to do — is process the invoices your client receives from their suppliers. That gap is where most of the "I need to replace Moloni" conversations really start — see our complete guide to invoice automation for what the receiving side actually involves.

So before anything else: make sure you're comparing the right thing.

Who Moloni Is For

Moloni is issuing-side software. If your client sends out invoices, quotes, receipts, and delivery notes, Moloni handles it. It's AT-certified, it produces compliant SAF-T files for the invoices you issue, and it scales from freelancers up to mid-sized businesses with inventory and multiple points of sale.

It's a good fit when:

• The client issues a meaningful number of invoices per month.
• You need integrated inventory, POS, or e-commerce connectors.
• The client wants a portal where they log in and issue invoices themselves.
• Your firm bills clients for Moloni-based work and they already know the interface.

If any of the above describe the situation, Moloni probably isn't the thing to replace. It's doing the job.

Who Faturiza Is For

Faturiza sits on the other side of the ledger. It's for the invoices your client receives — the PDFs arriving in their inbox, the supplier portals they have to log into, the paper receipts that end up photographed on a kitchen table on the 9th of the month.

Faturiza extracts the data, files the originals in your client's own Google Drive, builds a register in Google Sheets, and exports a SAF-T file for the received-invoices side. It's built around the accountant managing many clients at once — a multi-client dashboard, not a per-company login.

It's a good fit when:

• The pain is inbound invoices, not outbound.
• You manage multiple client portfolios and hate logging into a different system per client.
• You want the original documents to stay in the client's Google Drive, not locked inside a vendor's database.
• Your bottleneck is data entry from supplier invoices, not the issuing of your client's own invoices.

Notice there's almost no overlap with Moloni's job.

The Side-by-Side That Actually Matters

Once you separate "issuing" from "processing incoming," the comparison stops looking like a feature race and starts looking like two different product categories.

None of those rows say "Moloni is bad." They say Moloni is a different tool.

When You Should Stay on Moloni

If any of this describes your situation, switching is the wrong move:

Your client issues invoices through Moloni. Replacing AT-certified issuing software is expensive and risky. Don't do it to save a subscription fee.

The inventory or POS module is load-bearing. Moloni handles retail scenarios — stock movements, barcodes, cash registers — that processing-only tools don't touch. If you rip that out, something else has to do the job.

Your client is comfortable and self-sufficient in the interface. Disrupting a working habit has a real cost. If the client issues 80 invoices a month in Moloni without asking you a single question, leave it alone.

You already have a separate workflow for incoming invoices and it works. If the problem the post below describes — drowning in supplier PDFs — isn't your problem, Faturiza solves something you don't have.

When to Add Faturiza (Alongside Moloni, Not Instead)

The most common outcome of this conversation isn't "switch from Moloni to Faturiza." It's "keep Moloni for issuing, add Faturiza for received invoices." That's the scenario we see most often.

Consider it when:

You're spending more time on data entry than on actual accounting. If 13 hours a month per client goes into typing supplier invoices into a spreadsheet or a system, that's the number to cut.

Your clients send invoices via six different channels. Email, WhatsApp, paper, supplier portals, shared drives — if collecting and organizing incoming documents is a monthly crisis, that's a processing problem, not an issuing problem. See our piece on fixing the accountant-client invoice workflow for the shared-folder pattern that works well next to Faturiza.

You want to own the document archive. Moloni stores the invoices it issues. But the received-invoices archive — which is what AT asks for when they want to see a supporting document — is the accountant's problem. Keeping it in the client's own Google Drive means you never have to worry about data portability when a client leaves or a vendor changes pricing.

You manage more than five clients. Multi-client dashboards save time in a way single-company tools can't. Switching between five Moloni accounts to check SAF-T status on the 10th of the month is a distinct kind of misery.

When Switching Makes Sense

The narrow case where replacing Moloni with Faturiza actually fits:

The client barely issues invoices. Maybe they're a pure service business that issues two or three invoices a month, or they issue through another channel entirely (a marketplace, a third-party platform that handles billing). Moloni is being paid for, but the issuing module is idle. Meanwhile, the real volume is on the incoming side, and nothing is handling it well.

In that case, yes — pay for the tool that matches the actual workload. But this is the exception, not the rule. If there's meaningful issuing happening, keep Moloni.

How to Decide in Under Ten Minutes

Answer three questions honestly:

1. How many invoices does the client issue per month vs. receive? If issuing is five and receiving is a hundred, you already know which side the pain is on.
2. What takes longer — issuing an invoice in Moloni, or processing a supplier invoice? If it's the second one by an order of magnitude, that's where to invest.
3. Where does the client actually want their original documents to live? Inside a vendor's database, or inside their own Google Drive that they control?

Most answers point to "add Faturiza, keep Moloni" rather than a switch. A few point to a genuine replacement. Very few point to "do nothing." The honest version of this comparison is that the two tools solve different problems, and most accountants need to stop treating the choice as either/or.

If your bottleneck is incoming invoices — supplier PDFs, multi-client chaos, the monthly SAF-T crunch on the received side — Faturiza was built for exactly that. The first 100 accountant teams keep 50% off forever during the beta. No sales call required.
