THE SHORT ANSWER

Reconcile each trade’s results to the whole company, including shared dispatch, management, premises, fleet and marketing costs. Keep cross-sold jobs and shared assets from being counted twice. Review the people and permissions required for each service. A mixed plumbing, HVAC and electrical business needs a consistent earnings and asset basis; adding separate trade multiples or contract books does not establish its value.

Build a consistent trade-to-company bridge

Separate earned plumbing, HVAC and electrical work where records support it. Identify shared technicians, billing, referrals and work billed under one trade but delivered by another. Reconcile job costs, refunds and warranties to the general ledger without counting cross-sold revenue twice.

Document the cost-allocation method and what each line already includes. Shared dispatch, management, marketing, rent and fleet expenses must be accounted for once, with the accountant’s review. Apparent high trade margins can simply reflect costs left outside a segment report.

Invented arithmetic, not a real company, allocation policy or market margin. Assumes both contributions exclude this same overhead and there is no duplicated revenue. Excludes other costs/adjustments, debt, tax, investment and cash timing; not established SDE or EBITDA.

Choose one explained earnings basis

Use the earnings basis guide to reconcile the whole-company measure. Identify the owner’s production, management, estimating and administrative work, including supported replacement costs under the proposed operating model.

SEC guidance addresses adjusted measures in issuer reporting.

Use it as a presentation reference with accountant review. Owner draws, vehicle principal, capital purchases and undeducted personal spending are not automatic expense add-backs. Do not remove shared recurring costs because a buyer might have an existing team; buyer-specific synergies require their own supported analysis.

Review operating permissions and capacity by trade

Prepare a jurisdiction/activity/person register for each trade rather than one blanket company qualification. Identify departures that could affect supervision, permits, staffing or actual production.

Illinois IDPH distinguishes individual plumbing licensing and contractor registration.

Use this state example for plumbing questions, not nationwide clearance or a rule for all three trades. Have the responsible authorities and advisors review each actual service. Use the plumbing guide, the HVAC guide and the electrical guide for distinct operating evidence.

Test actual drive time, completed jobs and dispatch cost if route efficiency is claimed. ZIP proximity, telematics software or cross-selling potential alone does not prove achieved earnings or assign a price premium.

Define shared assets and comparison scope

SBA sale guidance addresses assets and liabilities in the agreement.

(SBA: closing or selling a business)

List shared vehicles, tools, equipment, inventory, receivables and open work only once in the agreed price scope. Review title, condition and liabilities; do not add all fleet value on top of a whole-business earnings value that already includes it.

Compare evidence with consistent measures, reporting periods and included assets. A national HVAC SDE statistic cannot simply become an electrical EBITDA multiple or a guaranteed blended company range. Use the working-capital worksheet to clarify delivery.

Support any claimed preparation benefit with actual before-and-after earnings, costs and comparison evidence. No fixed route, recurring-revenue or management premium is established here.

Owner questions

Can I add the three trade valuations without shared-cost review?

Reconcile duplicated revenue, shared overhead, assets and obligations before using any combined indication.

Does cross-selling potential establish current value?

Separate achieved results from forecasts and buyer-specific assumptions.

Does preparation guarantee a percentage increase in sale price?

No. Evaluate achieved earnings, costs, transfer conditions and relevant comparison evidence.

Use explicit assumptions and keep the result as a starting point for your advisors.
