Built for the people who actually run things
The problem

Administration shouldn't take longer than the work.

You finished the job at 6pm. Now there's a quote to redo, an invoice to type up, an expense receipt somewhere in the van, and a client asking when you're free Tuesday. It should take minutes, not hours. It should be simple, not frustrating. It should never cost you your free time.

01
📄

Quote sent, client notified

Tell izi the job and the price. It builds the quote, sends it as a PDF, and lets you know when the client responds — or when they need a reminder.

02
📎

Invoices handled fast

Turn any quote or a quick message into an invoice — izi prepares it and sends it straight to your client.

03
🧾

Expenses in one place

Snap a receipt and izi takes care of the rest — logged, sorted, ready for tax time.

Meet izi

Your business assistant. Always on, always ready.

izi is the chat-first half of bizi. Generate quotes, log expenses, monitor client responses, and make changes on the go — all in plain chat. Here for you, anytime.

01

"Send a quote to Norvik d.o.o. — 8 hours electrical."

izi pulls their contact details, asks you what info is missing, sends a branded PDF to the client.

02

"I just finished a job for BlueLine d.o.o. — send them an invoice."

izi converts it into an invoice and sends it to the client and your accountant.

03

"Add StoneBridge j.d.o.o. to my clients."

izi updates your client base with new data — no forms, no fields to fill.

04

Snap a receipt — it's logged.

Send a photo of the receipt to izi. Amount read, category picked, running totals updated.

Why bizi

Two ways to use it. Pick one. Or both.

Most business tools force you into their workflow. bizi flexes around yours — whether that's a clean app you tap through, or a chat where you just say what you need.

The app

Simple enough that nobody needs a tutorial.

Four sections. Big buttons. The numbers you care about up top. First invoice out in under two minutes.

→ Tap + New invoice
→ Pick a client
→ Add a line
Send.
izi the agent

Or skip the app entirely. Just text.

izi runs the same workflows over WhatsApp, Viber or Telegram. The chat is the interface. No app to open, no tabs to find, no password to remember. You already know how to use it.

FAQ

Questions worth answering up front.

When does bizi launch?+
We're rolling out access in waves over the coming months. Joining the waitlist puts you in the next batch — the earlier you sign up, the sooner you'll get a key.
How much will it cost?+
Pricing isn't final, but the goal is simple: cheaper than the time you waste on admin today.
Is my data safe?+
Yes. Your business data is yours, encrypted in transit and at rest, hosted in the EU, GDPR-compliant. izi uses your data to help you — never to train models for anyone else.
What languages does izi speak?+
At launch, izi will be fluent in English, Croatian, Serbian, Slovenian — other languages will be added soon after.
Do I need WhatsApp/Viber/Telegram to use bizi?+
No. The app on its own (web, iOS, Android) does everything. izi-in-chat is an option, not a requirement — if you'd rather tap through a clean app, that's a perfectly good way to use bizi. Most people will end up using both, depending on the moment.
I'm not a tradesperson — can I still use bizi?+
Absolutely. bizi is built for anyone who runs a small operation: hairdressers, freelance designers, photographers, consultants, small studios. If you send quotes, issue invoices, and want admin to take less of your day, you're our person.
Get early access

Be one of the first to chat with izi.

Join the waitlist for early access, and the chance to shape what izi can do. No spam — just the launch email and the occasional behind-the-scenes update.

You're on the list.

We'll email you when your access opens. In the meantime, tell a friend with a small business — or one with a shoebox of receipts.
