Minutes, not days
The first pass is done before you open the file. You review the exceptions, not every line.
Loopbooks is your AI buddy for accountants' everyday tasks. While it handles the repetitive work, you save time to focus on what really matters: helping your clients.
For UK accountants. We start with VAT returns.
The problem
Chasing documents, re-entering figures, verifying numbers. Your value isn't the busywork. It's the time you spend making your clients more tax-efficient. You can't automate judgement, but you shouldn't be spending your best hours on transaction-level work that doesn't need you.
How it works
The heavy lifting is automated, starting with VAT. Every number still passes a human before it reaches HMRC.
Loopbooks plugs into the accounting tools you already use and pulls everything into one place. Your source of truth stays where it is.

Bella, your AI buddy inside Loopbooks, works transaction by transaction. She matches, checks the tax treatment and raises only what needs a human, each flag with a suggested fix and the evidence.

Accept, change, or ask the client in a few clicks. You see exactly why each item was flagged.

A plain-English question goes to your client; they tap answers on their phone. Clean, confirmed, audit-trailed.


We process the return so you don't have to. Reconciled, validated, signed off. No re-work.

What you get
Loopbooks takes the first pass on every return. What reaches you is a short list of decisions, not a pile of lines.

Our Differential
Take on more returns without taking on more people. Your costs follow your volume, and the margin is yours.
Hours back on every job. Spend them on higher-value work, or take on more clients.
Pay per use, one credit per run. Your cost scales with volume, not headcount.
VAT today, Self Assessment and Corporation Tax next, all from the same balance.

Built for regulated work. Bella shows her working, nothing is a black box. Every output is reviewed by a professional before it is filed, with a complete audit trail. GDPR-safe, built on Anthropic, your data is never used for training.
