Quento AI Chat lets you create invoices, update clients, and check payments using natural language commands. Built-in voice input. No more manual forms.
Quento now includes a native AI chat built directly into the app. It is designed for real Quento work: creating invoices, updating clients, checking overdue payments, and moving faster without jumping through forms.
Invoicing with AI
The fastest way to understand Quento AI is to use it for the tasks you already do every day:
create a draft invoice from one sentence
update the current invoice without leaving the page
find clients, products, and companies with natural language
ask quick business questions about revenue, overdue invoices, or recent activity
Examples:
"Create an invoice for NIP 5832947165, laptop 1250 PLN"
"1250 is gross"
"Add programming, 20h at 120 PLN per hour"
"Show overdue invoices"
"Which client owes me the most?"
Built into Quento
Quento AI opens from the floating assistant button and works in context. You can keep the chat in a drawer, continue in a full-page view, and use quick actions to jump to the right record or screen.
It can explain where to click, but when the request is clear it can also do the work for you.
Voice Input
Quento AI also supports browser voice input, so you can dictate a request instead of typing it.
Try It
Start with one real request from your workflow and see how far you can get without touching a form.
Create legally-compliant correction invoices linked to originals. Full KSeF support for Polish corrections. Automatic PDF generation with correction badges.

Tips for Best Results
Create "Template" Invoices
Set up draft invoices for your most common service combinations. Don't issue them - just keep them as templates to copy whenever needed.
Copy from Your Best Examples
Have a particularly well-structured invoice? Use it as your base for future bills to maintain consistency.
Combine with Labels
Add labels like "monthly-template" or "package-a" to invoices you copy often. They'll be preserved when copying, helping you stay organized.
FAQ
"Can I copy any invoice?"
You can copy draft, issued, and paid invoices. Cancelled and overdue invoices cannot be copied.
"Does copying affect the original invoice?"
No - the original stays exactly as it was. You're creating a brand new invoice that starts as a duplicate.
"Can I copy an invoice from a different client to use for another?"
Yes! The copy keeps the original client selected, but you can easily change it before saving.
"Do copied invoices keep their history or payments?"
No - the new invoice starts fresh with no payment history, email records, or KSeF submissions.
"Is there a limit to how many times I can copy an invoice?"
Copy as many times as you need. Each copy is a completely independent new invoice.
Ready to Save Time?
Next time you need to create a similar invoice, skip the manual entry. Just hit that copy button and start from a solid foundation.

Big news for businesses invoicing in Germany - Quento now supports XRechnung, Germany's mandatory e-invoicing standard.
What is XRechnung?

Mandatory for German public sector since 2020
Coming for B2B transactions between 2025-2028

If either condition is met, the XRechnung option appears automatically - no configuration needed.
Simple Process:

XRechnung auto-generates - proper XML structure, VAT IDs, tax codes
Download or email - get the XML file directly or attach to emails
Multiple Ways to Get Your XRechnung

Click the "Download" dropdown on any invoice with a German client
Choose "Download XRechnung XML" to get the XML file instantly
Also available: standard PDF download from the same menu

XML file attaches automatically alongside the PDF
Both options validate your client data first - no surprises, no errors.

Never forget to send invoice copies to your accountant again. Set up your accounting email once, and send clean bookkeeping copies with a single click.
We've all been there - you send an invoice to a client, and then realize hours (or days!) later that you forgot to send a copy to your accountant.
No more! Starting today, Quento makes it easy to keep your accountant in the loop with dedicated bookkeeping copies.
Watch the Tutorial
See this feature in action! Watch our step-by-step video guide:
You can now add an accounting email address to your company profile. When you've sent an invoice to your client, use the new "Send Copy to Accountants" button to deliver a standardized bookkeeping copy - completely separate from your client email.
Important: This is NOT automatic. You have full control - send copies only when YOU decide your accountant needs them.
Why This Matters
Two Separate Actions
Sending to your client (with payment instructions and custom messages) and sending to your accountant (clean bookkeeping copy) are now completely separate actions. No more "Reply All" disasters!
Standardized Format
Your accountant gets a clean, professional copy marked "For Your Records" - no payment buttons, no custom client messages, just the facts they need.
Never Forget Again
Once you save your accounting email in company settings, it's pre-selected every time. One click, and your accountant has the invoice.
Perfect for Teams
Add multiple recipients on the fly - your tax advisor, CFO, bookkeeper, or business partner can all receive copies when needed.
How It Works
One-Time Setup (30 seconds)
Go to Company Settings
Find the "Accounting Email" field
Enter your accountant's email address
Click Save
That's it! Your accounting email is now saved for future use.
Sending Copies to Your Accountant
After sending an invoice to your client, you'll see a new button: "Send Copy to Accountants"
Click it and you'll see:
- Your saved accounting email pre-checked (ready to go!)
- Option to add additional recipients (tax advisor, CFO, etc.)
- One-click send - no editing, no customization needed
The standardized email format keeps it clean and professional for bookkeeping purposes.
What Your Accountant Receives
Your accountant gets a simple, professional email:
Subject: Invoice #123/01/2026 - For Your Records
This is a copy of the invoice sent to ABC Company Ltd for your bookkeeping records.
Attachment: Invoice12301_2026.pdf
No payment buttons. No client-facing messages. Just the invoice they need for your books.
Perfect for Tax Season
Build a complete paper trail throughout the year. Your accountant has every invoice as you send them - no scrambling to export reports or forward emails when tax time arrives.
Real-World Use Cases
Monthly Bookkeeping
Send copies at month-end so your accountant can close your books without chasing you for invoices.
Quarterly VAT Returns
Forward all VAT-eligible invoices to your tax advisor as you create them.
Year-End Prep
Your accountant already has everything - annual reporting becomes a breeze.
Client Disputes
When a client claims they never received an invoice, your accountant has the proof in their records.
Frequently Asked Questions
Q: Do I have to send copies every time?
A: Absolutely not! This is completely optional. Use it only when your accountant needs a copy. Your normal "Send to Client" workflow is unchanged.
Q: Will my accountant see the email I send to the client?
A: No! The accountant receives a completely separate, standardized email designed for bookkeeping. Your client communication remains private.
Q: Can I send to multiple accountants?
A: Yes! Your saved accounting email is pre-selected, but you can add as many additional recipients as needed using the "Add recipient" button.
Q: Can I customize the message to accountants?
A: No, and that's intentional. The standardized format keeps everything professional and consistent for bookkeeping purposes. Your accountant will appreciate the consistency.
Q: Can I send copies of old invoices?
A: Absolutely! Open any invoice (even ones from last year) and use "Send Copy to Accountants" to forward it to your bookkeeper whenever needed.
Q: What if I don't have an accounting email saved?
A: No problem! You can still use the feature by adding email addresses manually when sending. To save time on future invoices, just add your accountant's email in Company Settings.
Q: Does this cost extra?
A: Nope! This feature is included in all Quento plans at no additional cost.
