Fair questions
Free, all features. We're Salary.io — we build payment, compliance and care infrastructure for companies working with international contractors. The invoice tool is the free, useful front door to that. If you ever want payouts, guarantees or compliance handled for you, we'll be around — no obligation.
Templates follow each supported country's invoice content rules (required fields, tax IDs, numbering). In countries where the law requires invoices to be issued through a government system (Brazil, Argentina, China, Portugal for residents), our documents are commercial invoices and clearly labeled as such. This is not legal advice.
We create your free account on the spot: a unique API key, your invoice history, company profile and sequential numbering. No password — we verify the email later, only when you sign in from another device. Marketing emails are a separate opt-in checkbox, never a condition.
A mode where a company generates invoices on behalf of its contractors (common for contractor platforms and finance teams). In the UK/EU it requires a self-billing agreement with the supplier — the invoice is marked 'self-billed', and we add the marker automatically.
We start with 15 countries and 6 invoice languages, scaling towards 150. If yours is missing, generate a generic international invoice — or tell us and we'll prioritize it.
