Our Story

Freelancers and small EU businesses just needed a clean PDF invoice and a fast way to check a client's VAT number, without wading into full accounting software. So we built exactly that.

    Tightening the shared look and feel We're aligning BlueInvoice's navbar, logo, and language switcher with the rest of the RapidFoundry family and rounding out translations.
  3. Next Goal
    Deeper e-invoicing compliance With the requirements reference pages already in place, the next step is turning that content into guided, structured e-invoicing exports as EU rules tighten.
