Selling a Business in 6 Months: A Checklist for Preparing the Financial Model, Legal Structure and IT Audit in Parallel

Selling a business is always a high-stakes, multi-stage process. For a deal to close successfully and at the maximum price, finding a buyer is not enough: you need thorough pre-sale preparation across three areas - the financial model, the legal structure and the IT audit. Experts agree that it is best to start 6-12 months before the deal - this timeframe lets you complete every procedure without rushing and to a high standard.

In this article we present a detailed checklist that will help you run the preparation across all three areas in parallel and reach the deal with an asset that is as attractive as possible to an investor.

Why does preparation need to be comprehensive?

The main goal of pre-sale preparation is to make the business transparent, legally clean and operationally independent. The buyer, especially a strategic investor, runs their own due diligence, and the fewer red flags they find, the higher the final price and the lower the risk of the deal falling through.

A comprehensive approach to preparation allows you to:

• Objectively assess the market value of the business;
• Identify and eliminate legal and financial risks;
• Increase the investment appeal of the asset;
• Shorten the time needed to close the deal;
• Minimise the risk of post-sale claims.

Preparation checklist: 6 steps to a successful deal

Month 1: Diagnostics and planning

Financial model.

• Run a rapid audit of the current financial condition of the business.
• Gather all the necessary information: financial statements for the last 24-36 months, forecasts, market and competitor data.
• Choose the valuation methodology: in practice the most common are the market approach (EV/EBITDA, P/E multiples) and the income approach (discounted cash flow - DCF).
• Establish a baseline reference point - the current value of the business that you will build from.

Legal structure.

• Conduct an initial legal due diligence in-house or with outside advisers.
• Review the constitutional documents: charter, founders' agreement, shareholders' agreement (if any).
• Collect information on the ownership structure and corporate governance.
• Compile a register of key risks for subsequent remediation.

IT audit.

• Carry out an initial inventory of the IT infrastructure: a list of all hardware, software, online services and digital assets.
• Assess the quality of documentation: availability of network diagrams, procedures and staff instructions.
• Identify critical issues that require immediate attention (no backups, unlicensed software).

Months 2-3: In-depth work and fixing issues

Financial model.

• Build a detailed financial model for 3-5 years with a monthly breakdown.
• Include three key blocks: revenue (broken down by source), costs (classified by line item), investments and start-up costs.
• Prepare alternative development scenarios (optimistic, base, pessimistic).
• Confirm the quality of revenue: analyse its structure, stability and diversification.
• Digitise all financial flows: ensure full transparency of cash movements.

Legal structure.

• Fix the legal defects identified: re-register title to assets, formalise employment relationships, put the contract base in order.
• Verify title to key assets: real estate, equipment, trademarks, patents. Make sure they are free of encumbrances.
• Run a Vendor Due Diligence (a seller-initiated review) - this surfaces issues before going to market and lets you prepare protective mechanisms.
• Prepare a comprehensive document package to hand over to the buyer: all contracts for the last 24-36 months, HR records, permits and licences.

IT audit.

• Run a deep technical audit: auditors receive full administrative access to the servers, read logs, analyse the architecture, test the backups and scan the network for vulnerabilities.
• Assess data security: access control systems, leak prevention, compliance with data protection law (GDPR).
• Check software licensing: make sure all software in use has valid licences.
• Test the backup and recovery systems - rehearse disaster recovery scenarios.

Months 4-5: Packaging and presentation

Financial model.

• Prepare the investment memorandum - the key document for presenting the business to buyers.
• Develop a presentation of the financial metrics: start with actual figures for the last 6-12 months, show the trend and key achievements, then explain in detail the logic behind the financial model.
• Assemble a package of supporting documents: management accounts reconciled against bank statements, tax filings, audit reports.
• Prepare answers to typical investor questions (Q&A).

Legal structure.

• Prepare a draft sale and purchase agreement that reflects all the risks identified and the mechanisms to mitigate them.
• Set up a legal Data Room (a virtual document repository) with convenient navigation for the buyer.
• Structure the deal: choose the optimal legal form (share sale, asset sale, merger, etc.).
• Prepare representations and warranties - this builds the buyer's confidence and reduces their risk.

IT audit.

• Prepare the IT section of the investment memorandum: architecture, technologies used, level of automation, development plans.
• Test all critical systems - make sure the business stays operationally resilient throughout the deal.
• Prepare an IT handover plan: logins, passwords, access rights and documentation for the buyer's team.
• Document all fixes and improvements made as a result of the audit - this serves as proof of the quality of preparation.

Month 6: Finishing preparation and going to market

Financial model.

• Run a final verification of the model with an independent appraiser or auditor.
• Calculate the fair price range based on all three valuation approaches (income, market, cost).
• Prepare a financial opinion for the negotiations with the buyer.

Legal structure.

• Run a final review of all documents before handing them to the buyer.
• Obtain all internal approvals (board approvals, shareholder meetings, etc.).
• Launch the buyer search through confidential marketing (qualified buyers under NDA only).

IT audit.

• Run a final security review - make sure all vulnerabilities have been fixed.
• Train key employees on how to work with the buyer's IT team.
• Prepare a post-sale IT support plan (optional - as an additional advantage for the buyer).

Frequently asked questions

How quickly can a business be sold in 2026?

The timeline depends on the size and specifics of the company. For small companies the process can take from two months; for medium and large ones, from 4 to 6 months. A full pre-sale preparation cycle is best started 6-12 months before the planned deal.

What is due diligence and is it mandatory?

Due diligence is a comprehensive review of the business before a deal, aimed at identifying and minimising possible risks. Without quality due diligence up to 70% of deals may collapse at the review stage. The seller is advised to run a Vendor Due Diligence before going to market.

How can you increase the value of a business before selling it within 6 months?

The main levers are: cleaning up the legal structure and assets, improving the transparency of financial reporting, reducing dependence on key clients and employees, implementing management accounting systems, and obtaining audit reports. It is also important to run an IT audit and eliminate all technical risks.

What documents are needed to sell a business?

A full package includes: financial statements for 24-36 months, bank statements, tax filings, contracts with suppliers and clients, constitutional documents and meeting minutes, HR records, permits (licences, certificates) and intellectual property rights.

Who is an M&A broker and why do you need one?

An M&A broker is a professional adviser who supports a business sale from valuation to closing. They help value the business correctly, prepare investment materials, find qualified buyers on a confidential basis, run the negotiations and structure the deal - which ultimately lets you sell the business for more and faster.
