Start a Plumbing Company by defining one licensed residential service scope, one completed-and-collected job policy, and a paid two-plumber dispatch schedule. The reference case assumes 120 monthly jobs at $650 each, calculates $18,538 of cash after maintenance, and reaches cash break-even at 80.89 jobs against a 142-job field-hour ceiling. Replace the assumed job value, materials, travel, callbacks, occupancy, vehicles, insurance, permits, and demand with evidence for the selected market before committing $326,049 of modeled funding.
One operating record starts with an inquiry and ends with a completed, documented, invoiced, and collected service job. Link the address, problem, triage, assigned plumber and vehicle, travel, diagnosis, estimate, authorization, materials, permit or inspection dependency, paid field hours, completion evidence, invoice, collection, warranty, and callback outcome. An inquiry, booked window, dispatched truck, estimate, deposit, material order, open invoice, callback, refund, or chargeback is not another completed revenue unit.
Repeat work helps only when the company solves the original problem without hiding callbacks or unpaid recovery time. Track customer source, booked-to-completed conversion, realized service and material revenue, materials cost, paid field hours, travel, permits, collection, callback cause, warranty recovery, and customer outcome by the original work order.
| Format | What changes | How to use it |
|---|---|---|
| Two-plumber residential service company | Two paid field plumbers in two service vehicles complete diagnosis, repair, and small replacement jobs within a defined territory | The reference format; work-order time, materials, permits, dispatch, collections, and callbacks constrain it. |
| New-construction or large remodeling contractor | Project schedules, crews, bids, retainage, change orders, inspections, and working capital replace short residential service-job flow | Use a separate project, labor, materials, billing, and financing model. |
| Commercial, industrial, sewer, septic, or fire-suppression specialist | Credentials, equipment, site risk, vehicles, crews, contracts, and job duration differ materially | Do not extend the residential service assumptions into these scopes. |
A founder prepared to manage licensed technical work, a paid field roster, dispatch promises, customer authorization, materials cash, two vehicles, permit dependencies, documentation, collection, and callback accountability. The format rewards complete work-order records because a full calendar cannot repair weak contribution, excessive travel, missing authority, or repeated return visits.
The figures below are a national wage reference scenario. The paid roster uses May 2025 BLS national occupational medians. Prices, customer volume, rent, equipment and other commercial inputs are authored assumptions. This is not a researched average startup cost, owner-income promise or a funding recommendation.
| Input or result | Reference | What to verify |
|---|---|---|
| Completed sales units | 120 completed and collected residential service jobs / month | 120 completed and collected jobs per month; demand requires evidence. |
| Net selling price | $650.00 | Build and test a relevant local menu, package or contract scope. |
| Revenue | $78,000 | Calculated volume × price, not observed sales. |
| Paid payroll | $21,742 / month | National wage medians × the stated hours × the 18% employer allowance. |
| Opening payments | $209,184 | Authored equipment and setup allowances, deposit and paid training. |
| Funding including reserve | $326,049 | Opening payments + deepest modeled operating deficit + retained buffer. |
| Mature operating profit (EBIT) | $18,338 / month | After the full paid roster and depreciation; before financing and income taxes. |
| EBIT break-even | 81.3 completed and collected jobs per month | A sales threshold to compare with capacity and tested demand. |
Two paid field plumbers supply 346.67 monthly hours. At 120 completed jobs, the authored ledger uses 258.00 full work-order hours, 9.00 callback hours, and 30.00 hours for training, stocking, and meetings. The entered 142-job ceiling uses 345.95 hours. Travel, diagnosis, authorization, supplier stops, permit dependencies, documentation, vehicle downtime, and callback history remain unverified; capacity is not demand.
Separate materials acquisition, job-specific permit, disposal, and specialty cost, payment leakage, and callback parts from paid payroll. Keep callback field hours in the capacity ledger so the same recovery work is not counted twice. Keep vehicle and fuel cost, commercial auto and liability insurance, utilities, dispatch software, phones, recurring marketing, professional support, uniforms, storage, training and administration visible. Model vehicle, tool and premises maintenance separately. Every amount remains an authored scenario input until a matched quote or operating record supports it.
The occupation rows are broad May 2025 cross-industry wage anchors for the disclosed paid roster. They do not establish local recruiting terms, licensing authority, overtime, on-call pay, benefits, employer obligations, owner distributions or unpaid owner capacity.

| Workstream | What the brief needs | Decision before spending |
|---|---|---|
| Two service vehicles and controlled stock | Vehicle purchase, upfit, registration, commercial coverage, secure tool and material storage, replenishment rules, fuel, parking, maintenance, tires, downtime, and replacement | Prove that both vehicles can be parked, insured, stocked, and kept available inside the selected service territory. |
| Diagnosis, repair, drain, inspection, press, and safety tools | Hand and power tools, drain machines, camera, press tools, ladders, leak testing, lockout controls, PPE, dust containment where applicable, calibration, inspection, service, and replacement | Tie each item to an included service and competent licensed worker rather than buying an undifferentiated tool package. |
| Dispatch, authorization, permit, invoice, and callback records | Inquiry, triage, promise window, address, assigned worker and vehicle, estimate, authorization, permit, materials, paid hours, completion evidence, invoice, collection, warranty, callback, and closure | Test one record from initial call through collected invoice and closed callback outcome. |
Compare installed scope, exclusions and payment dates. Do not treat an unquoted item as zero or count a bundled installation twice. How to compare equipment quotes and build the opening budget explains a reusable quote ledger.
Name the jurisdiction, license holder or qualifying person, worker credentials, residential services, excluded services, permit triggers, inspection steps, customer documents, warranties, and any federal RRP exposure.
Time intake, dispatch, travel, diagnosis, authorization, supplier stops, permit dependencies, productive work, documentation, cleanup, collection, quality control, and callbacks. Do not schedule one plumber or vehicle into simultaneous jobs.
Replace every opening allowance with a delivered quote, applicable fee, policy, lease term, supplier arrangement, and payment date before financing the launch.
Track inquiries, accepted scope, booked windows, dispatched jobs, completed and collected jobs, realized service and material dollars, all paid hours, direct cost, travel, callbacks, and work refused because scope or capacity was unavailable.
| Measure | Why it changes a decision |
|---|---|
| Completed and collected jobs by service scope | Separates delivered revenue from inquiries, appointments, estimates, deposits, material orders, open invoices, callbacks, refunds, and chargebacks. |
| Realized service and material revenue | Shows whether the entered $650 job value exists after discounts, tax treatment, refunds, collection loss, and the actual job mix. |
| Materials cost, permits, disposal, and supplier credits | Connects the job mix to contribution and working cash instead of relying on a markup rule. |
| Paid field hours by work-order stage | Makes travel, diagnosis, authorization, supplier stops, permit waiting, productive work, documentation, cleanup, stocking, training, and callbacks visible. |
| Callbacks tied to the original job | Connects recovery travel, diagnosis, labor, parts, refunds, supplier credits, customer result, and closure to the sale that caused them. |
Review actuals against the scope you priced. If an extra service, new trading hour or more distant client changes the work, update the roster and contribution calculation before expanding.
Take the exact entity, ownership, qualifying license holder, worker credentials, service territory, storage and dispatch address, two vehicles, included plumbing scope, water-heating work, drains, gas work, excavation, paint disturbance, materials and wastes, employees, customer documents, warranties, insurance, advertising, and permit triggers to the responsible state board, municipality, building department, insurer, fire authority, environmental office, and advisers. Ask which licenses, registrations, permits, inspections, bonds, insurance, tax, safety, lead, consumer, and record rules apply.
Each state profile links to official registration, tax and employer routes, together with the questions still requiring an address-specific answer. How to find the permits and approvals your business actually needs provides the record to keep.
Stop when cash break-even requires more completed and collected jobs than the two-plumber time ledger can deliver, when the qualifying license or local permit path is unresolved, when quoted revenue depends on unlicensed scope, when material and callback records do not reconcile, or when vehicles, insurance, parking, premises use, safety, and lead-safe obligations remain unpriced.
Write a response that changes the actual cause: narrower scope, a different site, revised paid staffing, a tested price or a delayed opening. A larger cash buffer only addresses a temporary timing gap.
Reconcile collected jobs, realized service and material dollars, direct job cost, paid coverage, callbacks, fixed cost, maintenance, and the two-plumber field-hour ceiling.
