Overview
The invoicing tool lets you create invoices, credit notes and estimates from your bookings and client files. This article covers the setup that works the same in every country: your company details, how document numbering works, and how to add more than one company.
Several countries have extra legal requirements on top of this setup. Check Rules for your country below before you issue your first invoice.
Before you start
You need the Invoices section in your sidebar. If it's greyed out or missing, see how to activate the invoicing tool.
If your property is in France, Spain, Portugal, Italy or Mexico, read Rules for your country first. Some of these countries need an extra activation before you can issue invoices.
Rules for your country
Amenitiz applies each country's invoicing rules for you, but some countries need an extra step or follow extra rules. Find your country below and follow the linked article.
France — before you issue invoices, activate French e-invoicing: see How to activate and use French e-invoicing (PDP). To save your company, Status, Business name, Currency, Address, City, Zip code and Country must all be filled in. Series names can only use letters, numbers and the characters - + _ /, with no spaces. Fiscal receipts are issued automatically: see How to find and download fiscal receipts.
Spain — your invoices are reported to the Spanish tax authority through Verifactu: see How to get your Amenitiz account ready for Verifactu in Spain. In the Canary Islands, Verifactu must be active before you can issue invoices with IGIC.
Portugal — invoicing must be activated with our partner Invopop and the Portuguese tax authority (AT) before you can issue documents: see How to activate Portuguese invoicing and How to set up and use fiscal invoicing in Portugal. Numbering works differently from the steps below: Amenitiz adds a document code (such as FT or NC) in front of each number, your series names must match the ones registered with the AT, a new series name applies from the next document you issue, and you also set a
Receipt series nameand aSimplified invoice series name.Italy — the invoices you issue are sent to the tax authority's exchange system (SdI) automatically, with no extra setup. To receive invoices from your suppliers, see How to handle passive invoices in Italy. For fiscal receipts, see How to create fiscal receipts from your Amenitiz account.
Mexico — invoices must follow the CFDI standard, which needs an activation and your CSD certificates: see How to activate e-invoicing for Mexico.
In any other country, the steps below are all you need.
Step-by-step instructions
1. Add your company details
In the sidebar, go to
Invoices.Click
Settings.Under
Company details, clickAdd a company— or clickEditon an existing company.
Fill in your company's details. The required fields depend on your country. You'll usually need:
Status
Business name
Address, City, Zip code and Country
Company registration number (where it applies)
VAT number
Currency
Also add the Email and Phone number you want to show on your invoices.
2. Set your invoice numbering
Scroll down to the Invoice settings section of the same form and enter a series name for each document type:
Invoice series name— used for your invoices.Credit note series name— used for your credit notes.
Every document number has two parts: the series name you choose, and a sequential number that Amenitiz adds automatically. For example, the series name INV2026 gives you INV2026-1, INV2026-2, INV2026-3, and so on. Enter only the series name, never a document number.
📌 Note
A series name must start and end with a letter or a number. Characters such as hyphens are only allowed between letters or numbers: INV-2026 works, INV2026- does not. Each company needs its own series names — two companies can't use the same one.
⚠️ Important: how changing a series name affects numbering
Numbering is continuous. It does not restart automatically at the start of a new year.
A new series name starts again at 1.
The change applies after your next day closing. Documents you issue before then keep the current series name and continue its sequence.
Documents you've already issued are never renumbered.
Example
Your invoices use the series name INV2026 and the last one is INV2026-145. You change the series name to INV2027 during the day. Invoices you issue that same day continue as INV2026-146, INV2026-147… After the day closing, the next invoice is INV2027-1.
3. Save your details
Click Save at the bottom of the page.
In France you can only save once every required field is filled in. In other countries you can save with missing fields, but complete them all: missing details can stop invoices from being issued or leave them incomplete.
Managing multiple companies
If you run several legal entities — for example different properties or brands — add a separate company for each one:
Under
Company details, clickAdd a company.Fill in the details for that company.
Enter its own series names in Invoice settings.
Click
Save.
When you create an invoice, you can choose which company issues it.
Example
If you run a hotel and a villa under different legal names, you can issue each booking's invoice from the right company.
FAQs

If your property is in France, Spain, Portugal, Italy or Mexico, see Rules for your country above. In other countries, the steps in this article are all you need.
When does a new series name take effect?
When does a new series name take effect?
After your next day closing. Documents you issue before then keep the current series name. In Portugal, a new series name applies straight away, from the next document you issue.
Why didn't my numbering restart after I changed the series name?
Why didn't my numbering restart after I changed the series name?
Most likely because you issued documents on the same day. The change only applies after the next day closing, so documents issued that day keep the previous series name. From then on, numbering starts at 1 with the new series name.
Why did my numbering restart at 1 unexpectedly?
Why did my numbering restart at 1 unexpectedly?
The series name was most likely changed — a new series name always starts at 1. Check the series names under Invoices → Settings → Edit.
Does numbering restart at the start of a new year?
Does numbering restart at the start of a new year?
No. Numbering is continuous across years. If you want a new sequence each year, change the series name (for example to INV2027) before you issue the first invoice of the new year.
Should I add a number, like "-1", to the series name?
Should I add a number, like "-1", to the series name?
No. Enter only the series name. Amenitiz adds the sequential number automatically, so adding your own number creates confusing document numbers.
Can I renumber invoices I've already issued?
Can I renumber invoices I've already issued?
No. Issued documents keep their number. A new series name only applies to documents issued after the change.
Why can't I save my company details in France?
Why can't I save my company details in France?
