The problem

Your account looks full. But it's not all yours.

With a partita IVA, taxes are due months after you get paid. Meanwhile, that money feels like yours.

Your bank balance lies

You see a full account and you spend. But part of that money already belongs to the tax office and INPS, and you find out when the F24 arrives.

June and November hit twice as hard

In June the balance for last year and the first advance for this year come due together. It's the month many freelancers discover they spent money that wasn't theirs.

Salary and partita IVA don't talk to each other

If you're also an employee, salary and invoices add up in your tax return. Working out what you really keep becomes a puzzle.

Zerva does the math on every payment: you always know what's yours and what to set aside.

For every situation

One app for every tax regime: forfettario, ordinario, employee, hybrid.

Pick your situation when you start. Zerva applies that regime's rules and shows you the results, not the formulas.

Forfettario

Partita IVA with revenue up to €85,000

On the forfettario flat-rate regime? On every payment Zerva tells you how much to set aside for tax and INPS. And it warns you before you reach €85,000.

Ordinario

Partita IVA with IRPEF brackets and VAT

In the ordinario regime, costs, VAT and IRPEF brackets all count. Zerva puts them together and tells you how much is yours after every invoice.

Employee

Salary only

Zerva works out your net pay, including the 13th and 14th month, takes out fixed costs and goals, and tells you how much you can spend this month.

Hybrid

The hardest case

Employee with a partita IVA

Salary and invoices together: Zerva adds up your income and gets you ready for the year-end adjustment. And it warns you if your salary goes over €35,000, the limit for staying in the forfettario.

INPS Gestione Separata, artisans and traders, and 11 professional pension funds with 2026 minimums.

How it works

How it works: three steps, a few seconds.

  1. Set up your profile

    Regime, line of work and, if you have one, your salary. Three screens, no account, no email.

  2. Log a payment

    Type the amount. Zerva tells you right away how much to move to your tax fund and how much is left for you.

  3. Reach every deadline covered

    See the next deadline, how much you've already covered and how much is missing. With a reminder before the day.

Features

Everything a freelancer needs. Nothing more.

Log a payment

One payment, five seconds.

Type the amount: Zerva tells you right away how much to move to your tax fund.

Deadlines

June and November balance and advances, no surprises.

Balance and advance payments estimated from your income, with how much you've already covered.

Safe to spend

How much you can spend today.

Taxes, fixed costs and goals are already taken out. The rest is yours.

Employee + partita IVA

Salary and partita IVA, together.

Payslips and invoices in one app: Zerva accounts for your combined income without mixing up the numbers.

Read documents · Pro

Upload F24s and payslips. Zerva reads them.

F24, CU and payslips read on your iPhone: codes and amounts link to your deadlines, net pay to your salary. Every figure is checked against the document's totals, and nothing is saved without your confirmation.

Beyond taxes

Not just taxes. Money, work and clients in one app.

Household spending, clients, quotes and documents sit right next to your taxes. So you always know what's yours.

Your money

Home and business, kept apart.

  • Lifestyle

    Rent, subscriptions and other fixed costs come out of Safe to spend automatically. If you're an employee, your 13th and 14th month pay go into the plan too.

  • Business expenses

    Software, equipment, courses and travel in a separate list. Under the ordinary regime they lower your taxable income; under the flat-rate regime they show what your business costs.

  • Savings goalsPro

    Amount, date and priority, with the instalments you've paid in. Zerva suggests where to start, like a safety cushion if you're on a fixed-term contract or a variable salary.

  • Cash forecastsPro

    Account balance, what's free today and your reserves. Expected income and expenses don't touch what's available until they actually happen.

Your work

Clients and deliveries, without heavy management software.

  • SchedulePro

    Deliveries and appointments with client, estimated time and expected value, taken from your price list.

  • Price listPro

    Pricing models, internal hourly cost and availability for each service.

  • Client card

    Billed, collected, outstanding and overdue for each client. If a payment is late, a reminder goes out in one tap.

  • Profitability per clientPro

    Average time to pay, accepted quotes, margin and the cost of your time. And how much each client weighs on your revenue.

Your documents

Signed quotes, ready in a few taps.

  • PDF quotes

    From price list to PDF with your business's logo, colour and details. Sign by hand on the screen and preview it before sending. With Pro, no Zerva branding.

  • From quote to invoice

    Accepted? It becomes an invoice in one tap, already linked to the client. It stays inside Zerva: the app doesn't issue or transmit invoices.

  • For your accountant

    Export a file for Excel, free. With Pro, a PDF summary report too.

  • Business card with QRPro

    Whoever scans it saves you to their contacts.

  • ToolsPro

    Thresholds, VAT, withholding tax, TFR and net to gross salary, all in one place.

  • Guide and glossary

    A practical guide to the partita IVA and a glossary with the terms that apply to your profile.

Ask Zerva

  • With the official source

    Answers about tax rules cite the Agenzia delle Entrate and INPS.

  • If it doesn't understand, it says so

    Instead of guessing, it asks you to rephrase the question.

Zerva doesn't replace your accountant: it gets you to them prepared.

FAQ

Before you download it.

Does Zerva replace my accountant?

No. Zerva helps you set aside the right money during the year and prepares a summary to bring to your accountant. The tax return is still their job. Zerva does not issue or submit invoices or tax documents.

Does my data end up on a server?

Your tax data doesn't: payments, invoices, clients and profile stay on your phone, and no account is needed. To verify your subscription and receive crash reports we use two external services, which only receive an anonymous identifier.

How accurate are the estimates?

They are indicative estimates, based on current tax rules and the data you enter. The more payments you log, the closer they get. The final figure is set by your tax return.

Does it work if I'm an employee and also have a partita IVA?

Yes. Enter your salary and Zerva accounts for your combined income. It also warns you if your salary goes over the limit for staying in the forfettario.

Which regimes and pension funds does it support?

Four situations: forfettario, ordinario, employee and hybrid (employee with a partita IVA). For contributions: INPS Gestione Separata, artisans and traders, and 11 professional pension funds with 2026 minimums.

What happens after the 14 days?

You go back to the Free plan, which stays free with no limits on payments or invoices. No automatic charge: you only pay if you choose Zerva Pro.

Is the app in English? Is there an Android version?

Not yet. Zerva is iPhone only, in Italian, on the Italian App Store. The tax terms it uses (F24, INPS, acconto, saldo) are the same ones your accountant and the Agenzia delle Entrate use.

Does Ask Zerva use artificial intelligence?

No. It recognizes your questions and answers with the app's own calculations, on your iPhone. That's why it doesn't make up figures: if it doesn't understand a question, it tells you.

What can I ask Zerva?

Taxes and deadlines, how much you can spend, payments by client or period, quotes, expenses and what tax terms mean. Questions about today are free; questions about the future and simulations are part of Zerva Pro.

I already have an invoicing app. Do I need Zerva too?

They do two different things. Your invoicing app issues the documents; Zerva tells you how much of that money is yours and how much to set aside for taxes and INPS.

Can I use it if I've just opened my partita IVA?

Yes, it's actually the best time. In your first year you usually pay no advances, but the following June the balance and the first advance come due together. With Zerva you set money aside from your very first payment.

Does Zerva read F24, CU and payslips?

Yes, with Zerva Pro. Upload a PDF or take a photo: Zerva reads codes, amounts and net pay on your phone, without sending the file to anyone. Figures confirmed by the document's totals are marked as verified, the others as to be checked, and nothing is saved without your confirmation. Entering data manually stays free.
