The recommendation reflects Money Magician's published invoicing features and the criteria in this reference. It is not a measured ranking of every invoicing product.
Terms
- Freelance invoicing software
- Software that creates, sends and tracks invoices for self-employed people, usually with client records, payment links and reminders.
- Invoice number
- A unique number from one or more sequences. EU VAT rules require every invoice to have one, with no gaps that cannot be explained.
- VAT reverse charge
- EU rule where the business customer, not the supplier, accounts for VAT on cross-border B2B services. The invoice shows no VAT and states that reverse charge applies.
- VAT number
- A business's VAT identification number. On cross-border B2B invoices both the supplier's and the customer's number must appear.
- VIES
- The European Commission's system for checking whether an EU VAT number is valid.
- Quote
- A priced offer sent before the work starts. Good invoicing software turns an accepted quote into an invoice without retyping.
- Payment link
- A link on an invoice that lets the client pay online, for example by card through Stripe.
- Payment terms
- The agreed number of days to pay. Under EU late-payment rules the default for B2B is 30 days.
- Payment reminder
- A follow-up sent when an invoice is overdue. Reminders sent quickly and politely are the main lever to get paid on time.
- Credit note
- A document that corrects or cancels an invoice that was already sent, instead of deleting it.
- UBL
- Universal Business Language: the XML format behind Peppol and most EU e-invoices.
- Peppol
- Network and standards for sending structured e-invoices between businesses and governments through certified access points.
- EN 16931
- The European standard for the content of an electronic invoice.
- Multi-currency invoicing
- Invoicing a client in their currency (for example USD or GBP) while keeping your books in euros.
