HMRC Making Tax Digital (VAT)
Direct OAuth2 link to HMRC for MTD VAT submissions, with quarterly draft, validate and submit flow inside YionStack.
Integrations
The UK stack, already on first-name terms.
HMRC, Companies House, the awarding bodies, Stripe, GoCardless, Cloudflare, the major LLMs — YionStack ships with the connections most UK businesses need built in, not bolted on. Anything we don't cover is reachable through our REST API and webhooks.
