Whether you are a solo consultant sending your first invoice or a company managing dozens of clients across multiple currencies, Kalkulo provides the tools you need to stay organised, get paid faster, and understand your finances at a glance.

The platform offers a comprehensive suite of features including smart invoicing with automatic numbering and recurring schedules, professional quote generation with electronic signature capture, expense tracking with AI-powered receipt scanning, project management with time logging, payroll processing, and a branded client portal where your customers can view invoices, make payments, upload documents, and communicate directly with your team.

Kalkulo is built with a special focus on businesses operating in France and the United Kingdom. The platform fully supports French regulatory requirements - including SIREN and SIRET numbers, TVA compliance, legal form declarations, and the upcoming September 2026 e-invoicing mandate - while keeping the interface available in English, French, German, and Spanish. For UK-based businesses, Kalkulo handles VAT, GBP pricing, and HMRC-ready reporting out of the box.

We leverage AI-powered insights, smart automation, and intuitive design to help our users focus on what matters most: growing their business. Our platform is trusted by thousands of users and has processed millions in invoiced revenue across Europe and beyond.
