CONFIDENCE SCORING

You always know exactly what to trust.

AI Stone doesn’t guess. Every extraction carries a confidence score — at the transaction level, the document level, and the batch level.

High confidence items are processed automatically. Low confidence items are flagged with both outputs shown side by side. Your judgment goes exactly where it’s needed.

Your client data stays in your systems. Full stop.

Not a SaaS platform. Not a shared cloud. Not offshore. A system deployed inside your own infrastructure — so no client financial data ever passes through AI Stone’s servers. Or anyone else’s.

WHAT AI STONE BUILDS

Automation systems for accounting firms.

Bank Statement Extraction

HSBC, Lloyds, Barclays, NatWest, Santander, TSB, Monzo — transactions extracted, validated, and balanced automatically.

Replaces: line-by-line transaction typing from PDF bank statements

Invoice & Receipt Processing

Supplier invoices and receipts extracted and validated. Net, VAT, and gross checked before anything reaches your software.

Replaces: manual invoice data entry and VAT/gross/net checking

Credit Card Statement Processing

Company card statements processed alongside bank accounts. Every transaction extracted, categorised, and ready for review.

Replaces: separate manual processing of company card transactions

Mixed Document Handling

Send everything in one go — unsorted. AI Stone identifies each document type, routes it to the correct extraction process, and flags anything it can’t classify.

Replaces: manually sorting client document batches before processing

Auto-Categorisation & VAT Coding

Transactions suggested against UK nominal codes and VAT treatment. Uncertain items flagged for your review — never guessed.

Replaces: manual categorisation against nominal codes and VAT treatment

Invoice & Payment Matching

Bank payments matched to extracted invoices automatically. Confirmed, near-matched, or flagged — nothing goes unaccounted for.

Replaces: manual comparison of bank payments against supplier invoices

Balance Reconciliation

Opening balance plus credits minus debits equals closing balance — verified mathematically, row by row, before anything leaves the system.

Replaces: manual opening-credits-debits-closing verification

Sole Trader Transaction Separation

Business and personal transactions split automatically from a single bank account — the most time-consuming sole trader task, done before you open the file.

Replaces: manual personal/business split — the most time-consuming sole trader task

Catch-Up Processing

Twelve months of mixed client documents — statements, invoices, receipts — processed into categorised, reconciled books ready for your sign-off.

Replaces: weeks of manual work to bring a new client’s books up to date

MTD & VAT Return Preparation

Quarterly income and expense summaries prepared from extracted documents — ready for submission through your MTD software. Your team files. AI Stone prepares.

Replaces: manual quarterly income/expense compilation from source documents

Year-End Working Papers

Cash reconciliation, creditors schedule, debtors schedule, and expense analysis — generated automatically once the books are clean.

Replaces: manual preparation of reconciliation schedules and working papers

New Client Onboarding

Historical records from a previous accountant — bank statements, old invoices, prior year data — ingested, structured, and pushed to Xero. Clean books from day one.

Replaces: weeks of manual historical record processing

THE OUTCOME

What changes for your practice.

More clients. Same team.

Your existing staff manage a larger client base — without working longer hours.

Clean books before you open the file.

Extracted, categorised, VAT-coded, and balanced — before your team touches it.

Your team stays in Xero. Or Sage. Or QuickBooks.

No new platform. No migration. The data entry disappears.
