Why firms choose BakuHub over generic bookkeeping tools


🔥 V6 Smart Bundle Engine

Built for the toughest accounts. Automatically link Gross Invoices to Net Bank Statements to calculate precise CIS deductions, or instantly categorize high-volume bank feeds for complex ITSA summaries.

🚫 Zero Hidden Multipliers

Legacy tools charge 2× or 3× credits to extract line-items. Whether splitting Labour vs. Materials (CIS) or itemizing mixed retail receipts (ITSA), we extract unlimited lines for a flat 1-credit rate.

🔍 Auto-Zoom Ergonomic UI

Protect your team's eyesight. Our smart-focus interface automatically zooms into the exact numbers on blurry, crumpled shoebox receipts and van dashboard invoices, tripling review speed.

🧮 Math-Safe Excel Exports

Parent totals are automatically replaced with "— Split" in Excel to guarantee junior staff never make =SUM() double-counting errors on complex tax returns. Backed by a full AI Audit Trail.

Frequently Asked Questions


Never. Legacy tools often penalise you by charging 2 or 3 credits for a single receipt simply because it has multiple items. At BakuHub, we charge a flat 1 Document Credit per physical page—whether it has 2 lines or 50. You pay for the AI engine, not hidden penalties.

To ensure transparent pricing, we use a strict "Standard Physical A4 Equivalent" rule. Since a real physical bank statement page holds exactly 25 lines, we calculate every 25 transaction rows in a digital CSV as exactly 1 Document Credit. You only pay for the exact compute power used to mathematically reconcile your data.

Security is our absolute priority. BakuHub operates on 'Inherited Enterprise Security' using AWS infrastructure and Auth0 identity protection with strict encryption. Most importantly, we categorically NEVER use your clients' private financial data to train public AI models. Your data is strictly ring-fenced.

No, BakuHub is the ultimate 'reconciliation engine' that sits before your general ledger. We process the messy paperwork, auto-calculate the CIS/ITSA deductions, and output 'Math-Safe' summaries. These reconciled files are designed to be easily imported into Xero or QuickBooks without double-counting errors.

Not at all. Our Standard and Firm plans operate on a flexible, rolling monthly basis so you can upgrade, downgrade, or cancel at any time. However, locking in the £299 Firm Plan before the April 5th tax deadline guarantees your "Founder's Edition" overage rate is permanently protected from future price hikes.
