Why preparation determines the price you achieve
The difference between a well-prepared sale and an unplanned one is rarely the quality of the underlying business. It is almost always the quality of the information a buyer receives, the confidence that management can run the company without the founder, and the absence of surprises during due diligence. Buyers price risk. Every unanswered question, every inconsistency in the accounts, every personal dependency adds a discount to their offer. Starting preparation twelve months ahead gives you the time to remove those discounts before they are applied.
Months one to three: get your financial house in order
Buyers and their advisers will request three full years of audited or reviewed accounts, monthly management accounts and a clear reconciliation between the two. If your management accounts have never been prepared consistently, or if they tell a different story from the statutory filings, this is the first thing to fix.
Beyond the numbers themselves, buyers scrutinise the quality of earnings. They will separate recurring revenue from one-off items, strip out owner-related costs that will not transfer, and adjust for personal expenditure run through the business. Do that analysis yourself first. Understand your own normalised EBITDA and be ready to walk a buyer through every adjustment with supporting documentation.
This is also the moment to review working capital. Buyers set a normalised working capital peg in the sale agreement. If your receivables are stretched, your stock is aged, or your payables are compressed in the run-up to signing, a buyer's advisers will find it. Correcting the pattern now means the trailing data looks consistent at the right moment.
Months three to six: reduce key-person and customer concentration
The two concentration risks that most often erode value in owner-managed businesses are the founder and a small number of large customers. Both take time to address.
On the owner side, a buyer acquiring a business where all supplier relationships, customer knowledge and operational control sit with one person is buying a risk. The remedy is deliberate: document processes, promote a second tier of management, and allow that team to run meetings and take decisions visibly. Buyers conduct management interviews. If the team cannot describe the business confidently without the founder in the room, that signals dependency.
On customer concentration, the question is whether any single customer represents a disproportionate share of revenue and, if so, whether that relationship is contracted and not personally dependent on you. Long-term supply agreements, framework contracts and renewal histories all support the story. If a key customer relationship is informal and verbal, converting it to a written contract before the sale process begins adds tangible value.
Months six to nine: legal and structural housekeeping
Legal due diligence is the stage at which sales most frequently slow down. The issues that cause delay are rarely large; they are usually administrative, but they take time to resolve once a buyer has raised them.
- Confirm that the company owns, rather than merely uses, its intellectual property. If key IP was developed by a contractor or held personally by a founder, an assignment agreement is needed before sale.
- Check that all employment contracts are signed, current and include appropriate confidentiality and post-termination restrictions. Buyers will flag missing contracts for senior staff.
- Review property leases: remaining term, break clauses and whether landlord consent is required on a change of control.
- Confirm that all regulatory licences, accreditations and certifications are current and transferable.
- Check the articles of association and any shareholders' agreement for pre-emption rights, drag-along provisions or consent requirements. Resolving shareholder mechanics before a buyer is in the room is considerably easier than negotiating them under time pressure.
If there are historic legal disputes, terminated contracts with outstanding claims, or HMRC enquiries not formally closed, take legal and tax advice on how to disclose and, where possible, resolve them before the process begins.
Months nine to eleven: prepare your data room
A data room is the structured repository of documents that buyers and their advisers work through during due diligence. Preparing it in advance, rather than assembling it reactively as requests come in, keeps the process moving and projects competence to the buyer.
A well-organised data room typically includes three years of financial statements and management accounts, the current year budget and latest forecast, customer and supplier contracts, employment contracts and an organisation chart, details of material assets, intellectual property schedules, regulatory documents and corporate records including board minutes.
The information memorandum your adviser prepares for prospective buyers is only as strong as the underlying information you provide. An adviser working from clean, consistent data can position the business correctly and anticipate buyer questions. One working from incomplete records cannot.
Month eleven to twelve: structure the process
For lower mid-market businesses, the choice of adviser and process structure matters alongside the preparation itself. A broadly marketed process with a large number of recipients works for certain businesses, but for owner-managed companies where confidentiality is important, a targeted approach to a curated list of trade and financial buyers is often more appropriate. Discuss with your adviser how the buyer list will be constructed, what information is shared at each stage, and how the process will be managed around the operational demands on you and your management team.
A note on timing
Business owners frequently begin thinking about a sale when a buyer approaches, when a personal circumstance changes, or when trading is particularly strong. None of those moments is the right time to start preparation; they are the right time to have already completed it. The businesses that achieve the strongest outcomes treat the eventual sale as a planned event, not a reaction to circumstances.
If you are considering a sale in the next one to two years and would like to understand what preparation looks like for your specific business, the team at Blash Advisory works with owner-managers and founders through every stage of the sell-side process.
