Deposits, progress payments and change orders in remodeling
Operational worked example · Owner-led residential remodeling crew with two employees and specialist subcontractors
Start with a defined scope and locally permitted deposit, then tie progress requests to evidence of completed work or delivered materials. Credit the deposit in the remaining payment schedule. Get changed scope, price and time agreed in writing before performing it, and forecast supplier and payroll due dates against actual customer receipts. The worked example below uses ordinary California rules and declared job assumptions; it is not a national deposit formula.

Separate authorization, billing and receipt
A signed price authorizes a defined scope. A milestone determines when a payment request is supported. An invoice records that request. A bank receipt makes the money available. Treating these events as one date hides the weeks when a crew has already incurred costs but the owner has not paid.
The existing educational remodeling case prices a project-equivalent at $38,000, with $12,800 of materials and $9,200 of specialist work. Its monthly engine uses 20.0 collection days as a simplified receivables assumption. It does not contain a signed homeowner payment schedule or customer-deposit financing. The job timelines below add article-local timing hypotheses only. Existing case scope; example assumptions
- Approve the defined work and price.
- Complete the agreed stage or deliver the specified materials.
- Document the stage and issue its supported invoice.
- Follow the due date and record cleared funds.
- Release the next purchasing and crew commitments against the resulting cash forecast.
Choose a lawful deposit before choosing a percentage
The operating method is useful across the United States; the limits in this section are California-specific. For an ordinary home-improvement contract without the statutory bond or approved joint-control exception, the downpayment ceiling is the lesser of $1,000 and 10.0% of the contract price. An expensive special-order item does not itself remove that ordinary limit. A customer loan does not automatically permit advance progress collection. BPC 7159(d)(8); BPC 7159.5(a)(3)-(5), (8); CSLB explanation
The code separately provides an exception for specified full-performance/payment bonds or registrar-approved equivalents or joint control. Do not assume that an ordinary contractor license bond qualifies. Our example assumes the ordinary rules apply. Contract form, cancellation rights, permits, lien documents and other state requirements still need review for the actual job; this worksheet is not a complete contract template.
A supplier can require money before the contractor may collect the same amount from the homeowner. Resolve that mismatch through verified supplier terms, staged delivery or business working capital. Renaming an advance a mobilization charge does not prove that the requested payment is permitted.
Credit the deposit and attach evidence to every stage
The illustrative payments below sum to the existing project price. Stage values are assumed contract allocations, not appraisals of actual work. They must be replaced by itemized, supportable work and delivered-material values. The first progress invoice credits the downpayment: otherwise the schedule would collect the contract price plus the deposit. A downpayment receipt does not itself establish completed work or job profit; track the remaining customer obligation alongside the cash.
| Trigger and evidence | This payment | Cumulative receipts | Completed work / delivered-material value |
|---|---|---|---|
| Signed contract; start follows applicable cancellation and permit requirements | $1,000 | $1,000 | Ordinary permitted downpayment; work not yet started |
| Stage A: documented delivered materials and completed protection/demolition; agreed allocation verified | $11,000 | $12,000 | $12,000 |
| Stage B: contracted rough work completed; agreed inspection evidence supplied where required | $14,000 | $26,000 | $26,000 |
| Stage C: contracted installations and finishes completed, with listed closeout work still outstanding | $10,000 | $36,000 | $36,000 |
| Final: remaining agreed closeout/punch-list scope completed and required documents delivered | $2,000 | $38,000 | $38,000 |
The final $2,000 is an agreed allocation to unfinished closeout work. It is not a universal statutory retainage requirement. Each trigger should name the work, materials and evidence that let both parties recognize completion. Avoid a vague halfway point, a calendar date alone or a requirement to finance undelivered goods. California requires explicit phase/payment detail and bars requesting or accepting excessive progress amounts under the ordinary rules. Payment limits; contract schedule provisions
Make allowance substitutions visible. Credit omitted base work before adding replacement work, distinguish a selection allowance from a fixed specification, and agree who bears price or delivery changes. A receipt or photograph may support delivery; it does not by itself establish the whole contractual milestone.
Stress-test receipts against supplier due dates
Suppose materials are paid in two installments and subcontract work in two equal installments. The normal first-stage payment arrives on day 9. In the delayed case it arrives on day 18, 9 days later; later receipts stay at their assumed dates. Suppliers still get paid on time. We assume delivery and completed stage evidence support each customer invoice before its receipt.
| Illustrative day | Cash event | Normal receipt balance | First receipt delayed balance |
|---|---|---|---|
| 0 | Receive $1,000 downpayment | $1,000 | $1,000 |
| 1 | Pay $6,000 supplier installment | −$5,000 | −$5,000 |
| 6 | Pay remaining materials $6,800 | −$11,800 | −$11,800 |
| 9 | Normal first-stage receipt $11,000; delayed case receives nothing yet | −$800 | −$11,800 |
| 12 | Pay $4,600 subcontract installment | −$5,400 | −$16,400 |
| 16 | Receive $14,000 second-stage payment in both cases | $8,600 | −$2,400 |
| 18 | Receive delayed first-stage payment; no new normal-case receipt | $8,600 | $8,600 |
| 20 | Pay final $4,600 subcontract installment | $4,000 | $4,000 |
| 24 | Receive $10,000 third-stage payment | $14,000 | $14,000 |
| 30 | Receive $2,000 final payment | $16,000 | $16,000 |
The deepest procurement-only deficit is $11,800 in the normal case and $16,400 in the delayed case: an additional $4,600 must bridge the delay. Both cases end with $16,000 after $22,000 of materials/subcontracts, because timing changes the trough rather than the contract price.
This is not the whole job cash requirement or a profit forecast. It excludes paid crew/owner compensation, overhead, payment fees, tax, interest, disputes and other jobs. Place their actual pay dates on the same calendar before committing. The published monthly payroll and reserve already exist; do not add this demonstration as another expense line. A negative job balance means the business must fund the obligation, not that a supplier can wait.
Approve changed scope before buying or building it
A request to move a wall can change demolition, electrical work, finish quantities, inspection sequence and trade availability. Write the added and deleted scope, drawings/specifications, net price, schedule effect and revised payment triggers before releasing the work. California requires the applicable written change order to be signed before its covered work starts, with specified content. BPC 7159(c)(5), (d), (e)(3)
| Change-order item | Amount or time | What must be checked |
|---|---|---|
| Additional agreed price | $3,800 | Exact added work, exclusions and payment trigger; no automatic percentage rule |
| Additional materials | $1,200 | Matched item quantity, tax/delivery and any credit for omitted base materials |
| Additional subcontract work | $800 | Written scope and trade availability |
| Regular-time employee effort | 16.0 labor-hours × $34.50 = $552 | Allocated effort cost; these hours must fit paid shifts or be repriced for overtime/extra cover |
| Assumed payment fee | $38 | Existing case percentage applied to the extra price; actual payment method may differ |
| Remainder after these allocations | $1,210 | Before other overhead, owner coordination, financing and tax; not net profit |
| Revised contract price | $41,800 | Original price plus this signed addition |
These 16.0 hours use 15.7% of the base case’s weekly productive crew capacity. They are employee effort, while crew capacity also includes the working owner. The $552 allocation uses the retained case wage and burden; fixed roster pay does not automatically become extra cash payroll. If the work displaces another job, the lost available capacity also matters. If it requires overtime or additional staff, obtain and price that different cost.
Assume the trade sequence extends completion by 2 working days in this example. That is a separate schedule assumption, not a result derived from the hours: curing, permits, inspection and subcontract access can govern elapsed time. Do not confuse a customer’s approval of the extra price with immediate cash collection. The new schedule still has to fit the applicable payment rules.
Keep disputes and final collection visible
Use a change log with proposed, approved, performed, invoiced and received states. A verbal request belongs in the proposed column; completed but disputed work belongs in a separate exposure column. Both consume time and money, but neither is a reliable receipt. Assign a named person to explain the price/time impact and obtain the decision before the crew proceeds.
| Record | Evidence to attach | Decision |
|---|---|---|
| Scope and allowances | Signed specification, quantities, exclusions and allowance reconciliation | Whether the requested work is already paid for |
| Milestone and invoice | Agreed stage value, completion/delivery record, prior receipts and deposit credit | Amount now supported and due under the actual contract |
| Change order | Reason, added/deleted scope, net price, time effect, signatures and revised stage schedule | Whether to release extra procurement or labor |
| Supplier/subcontract liability | Due date, deposit/balance terms, invoice and payment status | Cash required before the customer receipt |
| Closeout | Punch list, applicable inspection/permit completion, warranty and required lien documents | Remaining obligation and final collection |
Review the next supplier liability and next supported customer receipt together before each procurement release. If a payment is late, update the job and business cash forecast, document the reason, and follow the actual contract and local rules for notices or suspending work. Do not assume that withholding work, demanding an early final payment or issuing a later change order cures the problem.
The decision is whether the agreed job can be delivered with collectible milestones and funded obligations. Use the financing guide for the existing business funding scope and the profitability guide for the retained monthly profit/cash distinction. The procurement bridge above remains its own narrow test.
