What is being compared in a multi-trade valuation?
Compare trade staff, skills, equipment and duties through supported earnings and the actual plan. More services alone produce no better offer or usable seller proceeds.
Define acquired work, records, people and authority before assigning any premium. Each trade needs supported continuity; an advertised service list proves no transferable capacity.
The valuation hub covers broader deal analysis. The multi-trade selling guide addresses preparation. Here, separate trade contribution and authority so the price discussion follows actual evidence rather than the combined business name.
Combined revenue may hide either trade's weakness or shared costs outside both. Review components and total, keeping unassigned costs visible before claiming more earnings.
How should the trade-level records be separated?
Separate completed jobs, bills, receipts, materials, labor, subcontractors and callbacks on the same period and accounting basis. These records show delivery and cost, beyond dashboard labels.
The gross-margin-by-line definition stresses defined costs. Compare both trades after equivalent labor expense. One result after burdened technician cost and another before it cannot support a fair margin ranking without correcting that difference first.
Reconcile trade totals to company accounts. Allocate a mixed job's invoice once using a supported basis. Keep unassigned costs visible until resolved. Crediting the whole same invoice to both trades creates revenue the combined company never earned.
The QoE definition explains verification of job coding, cost timing and reconciliation. Trade dashboards are inputs rather than proof those questions or omitted costs are resolved.
What should the comparison table contain?
Use matched costs and required resources. This diligence worksheet ranks no business type; fill it from records and plans before judging the proposed purchase.
| Criterion | Plumbing-only company | Plumbing plus HVAC company |
|---|---|---|
| Revenue evidence | Plumbing jobs, billing, and collections | Separate plumbing and HVAC jobs reconciled to combined revenue |
| Direct costs | Defined field labor, materials, subcontractors, and callbacks | Equivalent cost categories for each trade |
| Shared overhead | Office, dispatch, facilities, systems, and management | Allocation basis plus any unallocated company costs |
| Credentials | Actual plumbing scope, entity, and qualifying people | Scope and qualifying requirements for every offered trade |
| Capacity | Technician skills, equipment, and scheduling | Trade-specific skills, equipment, and competing capacity demands |
| Customer overlap | Actual channels and repeat work | Documented cross-trade activity and related acquisition costs |
| Investment | Plumbing fleet, tools, systems, and working capital | Trade-specific investment plus shared-resource requirements |
Check payroll and operating records for charted staff, trade duties, time and availability. A combined chart alone proves no capacity to cover both services.
Disclose different software or accounting methods. Matching labels without underlying cost treatment creates false comparability. Show missing records or adjustments beside each trade's result.
What does a worked numeric example show?
Assume hypothetical plumbing revenue of $600,000 and $300,000 defined direct costs. Its $300,000 contribution less $150,000 overhead and $80,000 management leaves a simplified $70,000 operating balance. These teaching inputs are no margin benchmark or actual company performance.
Assume HVAC adds $400,000 revenue less $240,000 equivalent direct costs, yielding $160,000 contribution. Added overhead of $70,000 and management of $30,000 leave $60,000. Combined operating balance is $130,000: plumbing's $70,000 plus HVAC's $60,000 under these assumptions.
Assume HVAC also needs $30,000 equipment cash. Simplified cash balance becomes $100,000. Debt, tax, working-fund changes, depreciation and other items are excluded. This is neither adjusted EBITDA nor a price estimate; avoid deducting the same purchase twice in a fuller model.
Why does shared overhead need careful treatment?
Separate trade and shared dispatch, space, accounting, insurance and leadership costs. Explain their drivers and any unresolved overhead. A convenient revenue split may misstate resource use.
Fund added dispatch time, help, space and tools. Existing resources have limited capacity; shared services prove no saving until actual extra needs and costs are checked.
ServiceTitan's KPI framework organizes vendor operating measures. It sets neither this company's cost allocation nor a margin benchmark. Align definitions with actual job and payroll records before drawing trade-level conclusions from those reports.
The adjusted EBITDA definition separates supported adjustments from forecasts. Keep future office savings in a labeled buyer case until change and cost are proved; they are no historical earnings.
What do industry classifications and announcements establish?
The 2022 NAICS Manual combines plumbing, heating and air-conditioning contractors within a classification. The reporting label proves neither every firm's actual trades nor a higher price for broader scope. Use the company's work records to define the acquired services.
The Sila/My Plumber Plus notice names a historical multi-service acquisition and its stated scope. It supplies company-specific activity rather than a paired price comparison. Preserve its date and disclosed facts before using it to frame buyer questions.
The notice gives no matched plumbing-only price or premium. It frames buyer-interest questions but fills no valuation gap. Another target needs supported earnings and offers.
Industry classes define reporting groups; deal notices describe events. Neither replaces company accounts or actual offers for the acquired work.
How does credential coverage affect the comparison?
List each trade, location, buyer firm and required person. Review roles after sale. Seller credentials alone prove neither buyer authority nor continued work without approvals or replacement staff.
California's C-36 scope and class directory illustrate distinct regulated scopes there. They grant no nationwide authority or blanket HVAC coverage. Check actual work and requirements for each entity and location before assuming all advertised services can continue.
PHCC Academy describes plumbing and HVAC training. Available courses establish neither issued credentials nor productive cross-trade capacity. Check actual staff skills, lawful roles and working hours before funding a plan that relies on those people across both trades.
The qualifier definition links personal credentials and company roles. Resolve sale-created gaps and fund lawful continuity. Sale alone removes no required work or cost.
What cash requirements can change the combined result?
Trades may need different equipment, stock, supplier terms and schedules. Diversification removes no cash need automatically; added service may require funds before receipts arrive.
The working-capital peg definition explains the closing benchmark. Here, test how HVAC changes operating receivables, stock and payables. Keep those requirements alongside earnings, so a added service's contribution does not hide the cash needed to support it.
Test seasons against recorded demand and staff. Complementary schedules need proof; trade labels alone show no balance. Peaks may still compete for crews, dispatch or cash.
Show forecast cross-selling apart from historical earnings. Name completed work, capable staff, marketing and fulfillment cost. A shared list is an opportunity, not booked revenue. Trace real jobs and receipts before assigning the assumed benefit to transferable earnings.
What do most owners get wrong about multi-trade pricing?
More services may add costs, management, equipment and duties. Fund these before calling revenue transferable profit. Test contribution rather than count all added sales as earnings.
Give no full same saving to both divisions. Reconcile to one company total, including omitted overhead and costs assigned to neither trade. Allocation can change division results without changing combined earnings; explain that before claiming any real new benefit.
A strong plumbing team proves no universal HVAC capacity. Check skills, credentials, roles and staff availability. Unsupported scope claims can weaken an otherwise attractive operating case, especially if the buyer must replace people or fund training before offering those services.
When does each operating model fit the decision?
Choose the plumbing-only option if
Prefer plumbing-only when supported earnings, authority, staff and investment fit the actual plan better than retaining HVAC. Compare equivalent acquired work and costs before deciding; a narrower label alone supplies no proof of a better purchase.
Choose the plumbing-plus-HVAC option if
Prefer the combined scope when HVAC adds supported contribution and useful capability after its costs, cash and authority needs. Test actual demand and capacity. Added services guarantee no valuation premium, free resources or reliable cross-selling benefit.
The platform/add-on comparison reviews organizational role separately from trade scope. Use this sequence to test service economics and continuity. A group label supplies no required proof.
- Reconcile each trade's work and direct costs.
- Allocate shared overhead and fund necessary management.
- Verify credentials, staffing, and equipment by service.
- Test cash requirements and proposed cross-selling assumptions.
- Compare actual offers using the same acquired perimeter.
