What Aven does - and doesn’t

Aven assembles R&D evidence packs for accountant review; Aven Reviewed adds expert review. Aven does not file with HMRC, determine your liability, select your scheme (merged vs ERIS), sequence loss relief, or guarantee any amount - those are your accountant or R&D tax firm’s responsibility. Figures are indicative and conservative. Nothing here is tax advice. UK only.

See if you have a defensible claim.

The Eligibility & Readiness assessment is free, takes a few minutes, and tells you honestly whether Aven is the right fit.
