Disorganised, incomplete or inaccurate accounting records are more common than most businesses admit, and the consequences compound over time. Missed entries, misclassified transactions, unreconciled ledgers and years of backlog don't just make audits stressful — they create real compliance exposure, distort your tax position and make it impossible to trust the numbers you rely on to run your business. Book Clean Up & Historic Accounting is the process of systematically reviewing, correcting and restoring your financial records to an accurate, complete and compliant state, regardless of how long the issues have been building up. LEAPRO's Chennai-based team specialises in exactly this work — combining experienced Chartered Accountants with structured review methods to work through backlogs efficiently, identify root causes, correct historical errors and hand you back a set of books your auditors, tax consultants and investors can rely on.

How We Work: Our Book Clean Up Process
We follow a structured, phased approach to every engagement, so nothing is missed, every correction is documented and you have full visibility throughout.
Stage
What Happens
Initial Assessment
We review your current books, identify the scope of issues, determine how many periods need to be covered and give you a clear written scope and timeline before any work begins
Data Collection
We collect all source documents — bank statements, invoices, vendor statements, GST returns, TDS challans, prior year financials and audit reports — needed to reconstruct and verify your records
Ledger & Transaction Review
Our CA team systematically works through your ledgers, identifying errors, duplicates, misclassifications and missing entries across all open periods
Reconciliations
We reconcile bank accounts, GST (GSTR-2A/2B), TDS (Form 26AS), vendor balances and customer balances period by period, resolving and documenting all exceptions
Corrective Journal Entries
All identified errors are corrected through properly documented journal entries, referencing the original transaction and the basis for correction
Balance Sheet Clearance
Suspense accounts, advances and other open items are reviewed and cleared. Assets are verified, depreciation is updated and write-offs are processed with proper approval
Trial Balance & Statements
A clean, reconciled trial balance is prepared for all corrected periods, with the P&L and Balance Sheet restated and reviewed for reasonableness
Handover & Documentation
A complete handover package is prepared — corrected books, reconciliation schedules, a list of adjustments made, recommendations for ongoing controls and a clean set of records ready for audit
Who This Is For
Startups preparing for their first statutory audit or approaching a funding round where investors will conduct financial due diligence
Businesses with months or years of unrecorded backlog, where day-to-day pressures meant accounting kept getting deferred
Companies that have changed accountants and discovered prior records are incomplete, inconsistent or don't match regulatory filings
Foreign subsidiaries where parent company reporting requirements have revealed discrepancies in the Indian books
Businesses preparing for a merger, acquisition or exit where clean, audited financials are a transaction condition
Companies that received a qualified audit report and need to resolve prior-year issues before the next audit cycle
Growing businesses transitioning to new accounting software where migration revealed errors or gaps in historical data
How AI Accelerates Our Book Clean-Up Work
Manual book clean-up across multiple years of transactions is slow, error-prone and expensive. LEAPRO uses AI-enabled tools to dramatically accelerate the review process without sacrificing accuracy or professional oversight.
Anomaly Detection
AI-assisted ledger scanning identifies unusual transaction patterns and outliers, flagging potential errors before human review begins
Duplicate Entry Identification
Automated matching identifies duplicate invoices, payments and journal entries across volumes that would take weeks to find manually
Classification Review
AI-supported checks compare transaction descriptions against chart of accounts mappings to surface likely misclassifications for CA review
Smart Reconciliation
Automated matching of bank statement lines to ledger entries across hundreds or thousands of transactions, with exception reports for unmatched items
GSTR-2A/2B Matching
Automated comparison of purchase register data against GST portal records to identify ITC mismatches and vendor filing gaps
Document Organisation
Bulk document tagging and classification by period, type and entity, creating a structured, searchable archive from unorganised records
Why Choose LEAPRO for Book Clean Up
Book clean up requires more than accounting knowledge — it takes deep familiarity with Indian compliance requirements, the ability to work across multiple periods at once, and the judgement to know when a correction is a simple journal entry versus one with tax or regulatory implications.

Frequently Asked Questions
There's no fixed limit — we've worked on backlogs ranging from a few months to several financial years. Scope and timeline depend on transaction volume, source document availability and correction complexity, which we assess and quote before work begins.
It depends on what we find. Some corrections carry GST or income tax implications — ITC reversals, additional tax liability or refund eligibility. We flag all such implications so your tax consultant can make informed decisions about amended filings, and we work closely with your advisors throughout.
Ideally yes, but we're experienced in working with incomplete records. Where documents are missing, we reconstruct entries from bank statements, GST returns, vendor communications and other available data, and we're upfront about what can and can't be reconstructed.
For a single financial year with moderate complexity, typically 3–6 weeks. Multi-year backlogs or complex entity structures take longer — we give a specific timeline estimate after the initial assessment.
Yes — this is a common engagement for us. Foreign subsidiaries often accumulate issues due to staff turnover, distance from headquarters oversight, or the complexity of dual reporting, and we're experienced in reconciling Indian books with parent company reporting requirements.
We provide a complete handover package — corrected books, reconciliation schedules, a log of all adjustments and recommendations to prevent recurrence — then can transition into ongoing FAO services to keep your books accurate going forward.
Absolutely. All client data is handled under strict confidentiality protocols, using secure, encrypted platforms for document transfer and storage, and never shared with third parties without explicit authorisation.
