Read the income statement together with collections, liabilities and the work required to run the wash. Reported profit is a starting point; it does not establish transferable cash flow or cash available after acquisition financing.
Make the periods comparable
Request monthly and annual statements on a consistent basis and confirm the accounting method. Compare matching seasons rather than annualizing one busy month. Explain reclassifications, missing months and changes in accounting before using a growth percentage.
Reconcile revenue with payment settlements, deposits and tax records as appropriate. Identify sales taxes collected, refunds, tips, prepaid obligations and discounts. For a multi-service site, separate wash, detailing, fleet and other streams so the total can be understood without counting member visits as new sales.
Look for costs outside the statement
Review the balance sheet, unpaid invoices, equipment leases and deferred repairs. A repair unpaid at period end can affect cash even if the income statement looks healthy. Capital purchases and loan principal are not interchangeable with ordinary operating expense.
Identify owner tasks and related-party arrangements. If the property owner charged little or no rent, build a consistent occupancy assumption before comparing business earnings. If the seller handled repairs personally, estimate the coverage a buyer will need.
Build and test an adjustment bridge
For each proposed adjustment, record amount, period, evidence and why it should change under new ownership. One-time does not mean every year has no unusual costs. Keep recurring needs and speculative improvements outside the historical add-back calculation.
Define whether the target metric is SDE for a working owner or adjusted EBITDA with appropriate management compensation. Then keep that definition consistent with the chosen comparison and staffing plan. The same result should not be presented under both labels.
Translate earnings into acquisition cash
Deduct the buyer's financing payments and realistic ongoing capital reserve when exploring cash availability. Add initial repairs and retained working capital to the funding budget. Taxes and lender underwriting require their own review; a positive P&L does not establish either outcome.
Bring a redacted earnings bridge and open questions to a scheduled call with Jason. Agree on the private channel for deeper records before sharing them. The homepage calculator can help explore assumptions, but reconciliation with the actual books remains essential.
Your decision worksheet
Use these questions to identify the records and decisions that matter to this topic. Bring the open items to your conversation; detailed documents can follow through an agreed private process.
| Question to resolve | Evidence to bring | Why it matters |
|---|---|---|
| Do receipts reconcile with reported sales? | Monthly books, settlements, deposits and explanations. | Investigate differences without inventing an acceptable variance threshold. |
| Which costs are missing or delayed? | Balance sheet, payables and equipment commitments. | See obligations that an income statement alone cannot show. |
| What metric am I buying? | Defined SDE or EBITDA bridge and owner-role map. | Avoid applying a comparison to a different earnings definition. |
| What cash remains after my plan? | Financing, reserves and required replacement costs. | Compare ownership cash rather than accounting profit alone. |
