Creating similar invoices just got a whole lot faster. Introducing Invoice Copy - a simple way to duplicate any existing invoice and use it as a starting point for a new one.

Why You'll Love This

Stop re-entering the same information. If you invoice the same client regularly or create similar invoices for different customers, copying saves you minutes on every bill.

What gets copied:

• All line items with descriptions, quantities, and prices
• Company and client details
• Payment terms and method
• Currency and language settings
• Labels you've assigned

What gets reset:

• Invoice number (auto-generated fresh)
• Dates (set to today)
• Status (starts as draft)

How to Copy an Invoice

Step 1: Find Your Invoice

Go to your Invoices page and find the invoice you want to copy.

Step 2: Click the Copy Button

Look for the copy icon (two overlapping squares) in the actions column on the right side of the invoice row.

Note: The copy button appears for draft, issued, and paid invoices. Cancelled or overdue invoices can't be copied.

Step 3: Edit and Save

You'll land on the New Invoice page with everything pre-filled:

• All line items from the original invoice
• Same client and company selected
• Matching payment terms and currency
• Your labels preserved

Make your changes - adjust quantities, update prices, add or remove items - then save as draft or issue immediately.

Perfect For

Recurring Clients

Invoice the same customer weekly or monthly? Copy last month's invoice, update the dates, and send. Done in seconds.

Similar Jobs

Do you offer the same services to different clients? Create one "template" invoice with your standard services, then copy and customize for each customer.

Retainers and Packages

Have set service packages? Build them once, copy as needed, adjust only what's different.

Error Corrections

Need to re-issue a similar invoice with corrections? Copy the original, fix what needs changing, and send the new version.

What Stays and What Changes

Copied to the New Invoice

Field	What Gets Copied
All line items	Products, quantities, unit prices, VAT rates, positions
Client & company	All billing details, addresses, tax numbers
Payment terms	Number of days for due date calculation
Currency	PLN, EUR, USD, or other selected currency
Payment method	Transfer, cash, card, or other method
Labels	All tags and categories assigned to invoice
Notes	Public notes for client and internal notes

Reset for the New Invoice

Field	What Happens
Invoice number	Auto-generated when you issue the invoice
Issue date	Left blank — set automatically when issued
Sale date	Reset to today's date
Due date	Calculated from payment terms after issue
Status	Always starts as draft (ready to edit)
Paid date	Left blank — no payment recorded
KSeF reference	Blank — for Polish e-invoicing system

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.

Head to your invoices page and look for the copy icon on any draft, issued, or paid invoice.

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

What is XRechnung?

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

Simple Process:

1. Create your invoice (web interface or ChatGPT)

Validated by ELSTER

Our XRechnung implementation has been tested and validated by ELSTER - the official German tax authority validator. This is the gold standard for compliance.

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:

Watch on YouTube →

What's New

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)

1. Go to Company Settings
2. Find the "Accounting Email" field
3. Enter your accountant's email address
4. 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.
