Unsigned plumbing change orders: how buyers test whether reported job margin is collectible

What changed after the original plumbing scope was agreed?

Start with the signed contract, estimate, plans, and exclusions. Identify the work the original price covered. Then trace each proposed extra to a request, reason, date, person, approval record, and completed task.

Keep customer requests distinct from the contractor's own decision to do more work. A site conversation, text, or field note may be evidence to review without settling the contract's approval requirements. Preserve the actual record and have counsel assess what it establishes.

The sell hub places this review in the broader sale process. A seller can make the file easier to assess before buyer diligence by separating agreed scope from disputed changes. That is more useful than labeling every extra either fully collectible or worthless.

A change-order margin bridge links original scope and proposed extras to approval evidence, recorded revenue, job costs, credits, cash, and remaining work. It is a reconciliation method. It does not decide legal enforceability or prescribe revenue recognition for every contract.

Which rules and contract terms govern the approval?

Read the actual change process, signatory authority, notice terms, and payment conditions. Identify the jurisdiction, project type, customer, and contracting parties. A residential consumer job may raise different rules from a commercial subcontract or public project.

California CSLB's home-improvement contract guidance discusses written scope and signed changes before the changed work begins. This is a California example within its stated context. It is not a complete rule for every plumbing contract across the country.

Ask counsel to review facts that do not fit the expected process. The customer may dispute who had authority, what was requested, or whether the work was already included. The buyer should know the unresolved question and the evidence needed to answer it.

Use the new-construction sale guide for the broader project model. Keep the change-order issue tied to specific contracts rather than assuming that all work for a builder has the same terms, approval route, or collection outcome.

Can the job file trace each extra to actual delivery?

Collect customer messages, field notes, dated photos, material records, time entries, outside-provider bills, and signed documents where available. Match them to the same job and change number.

Ask staff to explain the sequence from the original scope to the final bill. Identify changes that were approved but not completed, completed but not billed, or billed while disputed. Those statuses need different operating and financial responses.

Preserve the original record when a staff member corrects a code or description. The buyer may need to see why the books changed, especially where a proposed extra was moved into the base job. A neat summary cannot replace that history.

The sale preparation guide helps organize the material before diligence. Assign the missing fact and next action to a named person. A file gap may be recoverable without changing the claim, while an actual scope dispute needs a separate review.

What does the claimed margin include?

Match recorded revenue to the original price, changes, credits, and the accounting policy used. Reconcile costs by task so the buyer can see which work produced them. Ask the CPA about timing and treatment; a contract-value bridge is not itself an accounting opinion.

Consider an illustrative job, with no real target data. Assume original scope of $50,000, signed extras of $7,000, and claimed unsigned extras of $8,000. If the books include all three amounts, recorded revenue is $65,000 under the example's assumption.

Assume recorded job costs are $52,000, producing a reported difference of $13,000 before other costs. Original scope plus signed extras totals $57,000, a $5,000 difference from those same recorded costs. That comparison exposes how much of the reported result depends on the disputed $8,000.

The example does not decide that $57,000 is fully earned or collectible, or that $8,000 must be written off. Costs may also need correction or more work may remain. Use the actual policy, contract, evidence, and cash to assess each amount before changing the valuation.

Does cash support the invoice, or is the balance still disputed?

Trace payments, credits, retainage where relevant, collection messages, and open objections. Match the money to the scope it pays for. A partial receipt may relate to the original job without resolving all extras on the same invoice.

Ask the customer and counsel through the agreed diligence process where confirmation is needed. Do not contact customers without the seller's authorized plan. The buyer should preserve confidentiality while obtaining enough evidence to assess the specific disputed balance.

Use the working-capital peg definition to discuss receivables, unpaid costs, deposits, and remaining duties with the CPA. Agree how the deal values and assigns each item. A face-value invoice is not automatically free cash delivered at closing.

Keep the forecast's collection assumptions visible. A buyer may choose a cautious scenario while a claim remains open, but it should state the amount, evidence, timing, and cost behind that choice.

What do payment waivers establish separately?

Read the actual claimant, payment, covered amount, date, scope, and exceptions with counsel. Identify whose rights the document addresses. The company may have paid a direct provider without establishing that every supplier or subcontractor has been paid.

California CSLB's waiver and release guidance distinguishes conditional and unconditional progress and final forms. Conditional forms depend on actual payment within their terms. These are California examples, not universal release rules or approval of every extra on a project.

Match the release to payment evidence and the claim it covers. Keep it separate from the customer's authorization record for additional work. A buyer should not infer that an otherwise useful release resolves a different scope dispute.

Record open claimant issues beside the affected job. Ask counsel which further evidence or action is needed. The schedule should explain the next response without promising clean title, an enforceable lien, or a guaranteed collection result from a general guide.

Can the system export support the margin bridge?

Request detailed job, change, billing, credit, cost, and payment records. Check the date range, filters, and fields included. Keep source attachments and authorization messages available so the buyer can trace a selected row back to the actual file.

ServiceTitan's report instructions explain exports and filters, including an option for aggregated data. Those features can change the detail received. They do not prove that an export includes all changes or that its labels establish approval, earned revenue, or customer acceptance.

Compare a sample with original job records before extending the model across the target. Find duplicate change numbers, canceled requests, missing costs, and credits posted in another period. Record the correction and its effect rather than silently replacing one total with another.

What sequence gives the buyer a supported forecast?

Build the review around evidence for each job rather than one overall discount to receivables. Separate records work from a legal dispute and future completion cost. The response should follow the gap found in the file.

1. Match the original scope and each proposed extra to the actual job.
2. Obtain qualified review of contract requirements, authorization, and disputed rights.
3. Reconcile completed work, costs, invoices, credits, cash, and open tasks.
4. Review payment releases separately and agree the closing treatment of each balance.
5. State unresolved collection assumptions and assign the next customer or job response.

The guide to selling a plumbing business helps place that process in diligence and closing. Have the future manager explain one agreed change and one disputed extra from the records. The buyer's forecast should preserve the difference between claimed revenue, supported scope, completed work, and cash.
