Frequently asked questions
We answer the most common questions about invoicing, quotes and how the tool works.
Do I need to be self-employed to issue invoices
Generally, yes: to invoice on a regular basis you need to be registered as self-employed or have a company. Issuing invoices occasionally without being registered can have tax implications; check with an accountant if this applies to you.
Can I make an invoice without being a business
Individuals cannot strictly issue invoices; instead, other documents are used, such as a receipt or a sale contract, depending on the transaction.
What happens if I make a mistake on an invoice already sent
You shouldn't delete or directly modify it: you need to issue a corrective invoice that fixes the error, referencing the original invoice.
How long do I need to keep invoices
Regulations require keeping issued and received invoices for several years (usually 4 to 7 years, depending on the country and type of obligation). Always keep a copy as PDF or Excel.
Does PreFactur store my data on a server
No. Everything is processed in your own browser; no information is sent to or stored on our servers. You can read more in our Privacy Policy.
How much does it cost to use PreFactur
Nothing. PreFactur is 100% free, with no document limits and no need to sign up.
Can I customise the colour of my documents
Yes, on both the invoice and the quote you can choose between several preset colours or a custom colour to match your brand.
Can I use the same numbering for invoices and quotes
It's recommended to keep separate series (for example, "INV-" for invoices and "QUO-" for quotes), since they're different in nature. PreFactur already suggests different prefixes for each document type.
