Due Diligence Services That Uncover What the Numbers Hide
The numbers in an information memorandum only tell part of the story. ABM Chartered Accountants conducts thorough financial and tax due diligence that verifies what you have been told, uncovers what has been left out, and protects you before you commit.
Every Figure Verified Before You Commit
Due diligence is the detailed investigation you carry out before buying a business, investing in one, or entering a major transaction. It examines the target’s financial statements, tax position, commercial contracts, and working capital to identify risks that could reduce value or create liabilities after completion. ABM Chartered Accountants delivers this with rigour.
Our ICAEW and ACCA qualified accountants review historical financials, normalise earnings, analyse the sustainability of revenue, check for hidden liabilities, and assess the target’s tax compliance across corporation tax, VAT, and PAYE. We deliver a clear report that tells you exactly what you need to know before proceeding.
What Our Due Diligence Service Covers
From financial verification to vendor reporting, here is how ABM Chartered Accountants gives you the full picture before you make one of the biggest decisions in business.
Financial Due Diligence
Verifying the target's reported earnings, assets, liabilities, and cash flow before you proceed.
Tax Due Diligence
Reviewing the target's corporation tax, VAT, PAYE, and compliance history for risks or exposures.
Commercial Review
Assessing revenue quality, customer concentration, contract terms, and the sustainability of income.
Working Capital Analysis
Modelling the target's working capital cycle to identify cash flow risks after deal completion.
Vendor Due Diligence
Preparing a due diligence report on your own business to give buyers confidence and speed up deals.
Due Diligence Reporting
Delivering a clear, actionable report that highlights findings, risks, and their impact on value.
Avoid Costly Surprises After the Deal Closes
The majority of failed acquisitions trace back to inadequate due diligence. Overstated earnings, undisclosed tax liabilities, customer contracts with no renewal certainty, or working capital that drains cash immediately after completion. ABM Chartered Accountants identifies these issues before you sign, giving you the leverage to renegotiate, restructure, or walk away with full knowledge.
If you are selling, vendor due diligence gives you a significant advantage. A report prepared by your own chartered accountants demonstrates transparency, answers buyer questions in advance, and keeps you in control of the narrative. It accelerates the deal timetable and builds the trust buyers need to commit.

Frequently Asked Questions
Here are answers to the due diligence questions we hear most often. Contact our team for tailored guidance.
What is financial due diligence?
Financial due diligence is the detailed review of a target company’s financial statements, earnings quality, assets, liabilities, and cash flow. Its purpose is to verify what has been reported and identify risks that could affect the deal price or your decision to proceed.
What does tax due diligence cover?
Tax due diligence reviews the target’s corporation tax returns, VAT compliance, PAYE records, and any open enquiries or disputes with HMRC. It identifies unpaid tax, incorrect claims, and exposures that could become your liability after the deal completes.
How long does due diligence take?
Timescales depend on the size and complexity of the target business. A straightforward review of a small company might take two to three weeks. Larger or more complex targets can take four to eight weeks. ABM Chartered Accountants works to your deal timetable.
What is vendor due diligence?
Vendor due diligence is a report prepared by the seller’s accountants before the business goes to market. It gives buyers confidence in the financial information, answers common questions upfront, and speeds up the transaction. ABM Chartered Accountants prepares these reports for sellers.
What happens if due diligence finds problems?
If we identify issues, you have several options. You can renegotiate the price, request warranties or indemnities from the seller, restructure the deal to limit your exposure, or in serious cases decide not to proceed. Our report gives you the evidence to support any of these positions.
How much does due diligence cost?
Fees depend on the size of the target, the scope of the review, and the deal timetable. We offer fixed-fee and staged-fee arrangements so costs are clear from the start. Contact ABM Chartered Accountants for a confidential discussion.
