## Summary

When choosing between Twilio and Vobiz, Indian companies face a decision that goes beyond feature sets - it is about localized reliability. Twilio’s billing is exclusively in USD, which exposes Indian firms to continuous currency fluctuation and a 3.5% conversion markup. Vobiz provides native GST invoicing, allowing you to claim input tax credits - an 18% direct saving that Twilio cannot offer. Vobiz is also purpose-built for the Indian telecom landscape, providing full compliance with TRAI and DND regulations out of the box, so your business stays operational without the risk of regulatory blacklisting.
