Plio overview

What is Plio?

Plio — AI-Powered UK R&D Tax Relief Preparation Software

Plio helps UK businesses prepare their own R&D tax relief claim information without replacing their existing accounting or project management software.

Its Lister AI assistant evaluates scientific or technological uncertainties, compares technical explanations with published research, identifies evidence gaps and recommends improvements.

Plio also helps businesses organise R&D projects, document qualifying cost allocations and prepare supporting information for HMRC claims.

Optional plans include employee time recording and R&D project management.

Plio is developed by Paylists LTD. It is a self-service software platform, not a tax advisory service.
