Small tools for the parts of billing nobody enjoys.
Peppol files, EU VAT, IBANs, SEPA codes: the formats a border puts in your way. Each tool does a single job, runs entirely in your browser, and asks for nothing. When one has saved you enough time to be worth automating, weBiller does the same job every month.
