Overview
The Invoicing Tool in Amenitiz lets you create invoices, receipts, estimates, and credit notes directly from your reservations or client contacts. This article walks you through setting up your company details, invoice numbering, and how to handle multiple legal entities.
Before you start
The Invoicing Tool is automatically activated for properties with more than 6 rooms (included in your plan).
If your property has fewer than 6 rooms, activate it through the
Marketplace— see how to activate the invoicing tool.
Step-by-step instructions
1. Add your company details
Before you start creating invoices, add your company information.
Go to
Invoicein your Amenitiz admin.Click
Settings.Under
Company details, click+ Add a company— or clickEditon an existing company.
2. Fill in your company information
Required fields depend on your country of registration. You'll typically need:
Status
Business name
Address, city, zip code, country
Company registration number (if applicable)
VAT number
Currency
3. Configure invoice settings
Within Company details, scroll down to the Invoice Settings section. Here you can define how invoice and credit note numbering works. If you previously issued invoices with another system, choose the numbering option that continues from your last invoice to keep the sequence consistent.
Each invoice and credit note includes a prefix to identify the type of document:
INV — used for invoices.
CDN — used for credit notes.
You can customise these prefixes to match your business or legal requirements.
📌 Note
Once your first invoice is created, the numbering sequence is managed automatically by Amenitiz and cannot be manually edited. Updating an invoice or credit note prefix automatically resets the sequence.
⚠️ Important: how prefix changes affect numbering
Invoice numbering in Amenitiz is continuous — it does not reset automatically at the start of a new year.
When you change a prefix, the new sequence applies at midnight. Documents issued the same day keep the current prefix and sequence; documents issued from the next day start at 1 with the new prefix.
Example: If your invoices currently use the prefix INV2025 (e.g. INV2025-145) and you change it to INV2026, invoices created the same day stay as INV2025-146, 147…. Invoices created from the next day start at INV2026-1.
4. Add your contact information
In the same Company details section, add the business contact information shown on your invoices and other client-facing documents. Recommended:
Phone number
Email address
Website
💡 Tip
Keep this information consistent with what's shown on your website and booking pages to maintain a coherent brand across all communications.
5. Save your information
Click Save at the bottom of the page.
France: you can only save once all required fields are filled in.
Other countries: you can save with missing fields, but completing all details is strongly recommended for accuracy.
💡 Tip
Fully completed company details unlock all invoicing and payment-related features without restrictions.
Managing multiple companies
If you run several legal entities (multiple hotels, properties, or brands), you can add a separate company for each:
Click
+ Add a companyunder Company details.Enter the required information for each company.
Configure invoice numbering and contact info for each one.
Click
Save.
When you create an invoice from a reservation, you'll be able to pick the appropriate company.
Example
If you operate both a hotel and a villa under different legal names, you can issue invoices from the correct entity for each booking.
FAQs
Why didn't my invoice numbering restart after I changed the prefix?
Why didn't my invoice numbering restart after I changed the prefix?
Likely because invoices were already issued the same day the prefix was changed. Prefix changes apply at midnight — documents created the same day keep the current prefix and sequence. Invoices issued from the next day start at 1 with the new prefix.
Why did my invoice numbering reset unexpectedly?
Why did my invoice numbering reset unexpectedly?
A reset usually means the prefix was changed (for example from INV2025-145 back to INV-1). To fix it, revert the prefix to its previous value under Invoice → Settings → Modify.
Can I reset numbering retroactively for a year?
Can I reset numbering retroactively for a year?
No. If invoices have already been issued for the new year before updating the prefix, the numbering sequence for that year cannot be reset retroactively.
Should I manually add "1" to a new prefix?
Should I manually add "1" to a new prefix?
No. The system automatically restarts numbering from 1 when you change the prefix — adding "1" manually creates duplicate numbering.
Does invoice numbering reset at the start of a new year?
Does invoice numbering reset at the start of a new year?
No. Numbering is continuous across years. If you want a yearly reset, update your prefix (e.g. INV2026) before issuing the first invoice of the new year.
Why can't I save my company details in France?
Why can't I save my company details in France?
In France, all required fields must be filled in before the company can be saved. Complete every required field — including registration number and VAT — and try again.
When does a prefix change take effect?
When does a prefix change take effect?
At midnight on the day you save the change. Documents issued the same day keep the existing prefix; documents issued from the next day onwards start at 1 with the new prefix.
