Contractor estimate deposits and payment schedules: a worked example

1. Separate the project price, payment request and balance

A $6,000 estimate with a $600 deposit still describes a $6,000 job. The deposit is one part of the payment schedule. If the customer pays it, the unpaid project balance becomes $5,400; the price does not become $6,600.

Put three labels in your worksheet: agreed project total, payments received and remaining balance. Keep invoices issued in another field because a requested payment is not necessarily a received payment. Our estimate versus invoice guide explains that document boundary.

Before discussing percentages, confirm the scope version and the amount being divided. List how any applicable separately stated charges are handled. The example below models only its stated project price, without separate charges.

2. Use milestones that describe finished work

“Second payment halfway through” leaves room for disagreement. Half the calendar, half the rooms and half the spending can describe different moments. Use a location and a completed task: “Preparation in rooms A, B and C completed and reviewed against the listed preparation scope.”

Choose milestones you can document without asking the customer to understand your internal labor budget. Identify who reviews the work, how the payment request is delivered and when payment is due after that event. A planned work date can help coordination, but it should not silently replace the milestone.

The FTC's home improvement guidance advises homeowners against paying the full project amount upfront and notes that down-payment rules vary. Treat this article as an organizing method, not a recommendation for a particular deposit percentage or a substitute for checking local requirements.

3. Make the schedule add up once

Every figure in this example is hypothetical. A painting contractor has priced a defined three-room project at $6,000. These amounts demonstrate the arithmetic; they are not customary payment terms.

The check is $600 + $1,800 + $2,400 + $1,200 = $6,000. Each row is a separate payment. The balance column assumes the earlier payments were actually received; it is not a statement of what has been paid on a real job.

For percentage schedules that produce fractions of a cent, calculate the final payment as the project total minus the preceding amounts. That prevents a small rounding mismatch.

4. Check the spending before the first progress payment

Build a short internal timeline of material purchases, labor payments and other commitments. In a second hypothetical calculation, $1,450 must leave the business before the preparation milestone, while the only customer payment received is the $600 deposit. The business needs $850 from other available funds to bridge that interval: $1,450 − $600.

That gap does not automatically justify a larger deposit. Reconsider purchasing dates, scheduling or whether the job fits your available resources, while respecting the applicable payment requirements. The SBA's financial management guidance identifies receivables, payables and available cash as items to manage. A payment schedule is useful only when it is compared with those real commitments.

5. Describe the deposit credit in plain language

Use wording that explains the numbers without inventing cancellation, refund or collection terms:

Example project price: $6,000 for estimate Q-104, revision 2. The proposed $600 initial payment is included in that total. Remaining payments are $1,800, $2,400 and $1,200 at the milestones listed below. Payment requests will identify the completed milestone and show payments already received.

Add the actual due timing and accepted payment instructions from your approved business terms. Do not label a deposit “nonrefundable” merely because you plan to order materials. Have project-specific payment and cancellation terms reviewed appropriately before using them.

The painting estimate template helps keep the scope reference beside the pricing information.

6. Keep the schedule and payment record in agreement

When a payment arrives, record its date, amount and reference against the job. Before issuing the next request, compare the schedule with that record. If $600 has already been received, avoid sending a request that treats the entire $6,000 as newly payable.

A revised scope may also need a revised payment schedule. Keep the original version, identify the changed total and explain how the remaining payments are affected. Do not spread extra work across the old installments without discussion. The guide to recording scope changes covers the operational handoff.

Before sending the schedule

• Match the schedule to the correct estimate number and revision.
• State whether listed amounts include all applicable project charges.
• Check that payments total the price exactly once.
• Define the work, location and review associated with each milestone.
• Separate requested payments from money actually received.
• Check purchasing and payroll timing against available funds.
• Confirm that the proposed terms have the required project-specific review.

Questions about deposits and milestones

Should every small job have several progress payments?

No. A short, clearly defined visit may not have meaningful intermediate milestones. Match the schedule to the work and applicable requirements, rather than dividing every price into the same number of installments.

Is the deposit extra money for materials?

In this example it is a payment toward the total, even if you use the cash for materials. A material cost in the estimate and a payment toward the estimate are different entries.

What if the planned milestone date moves?

Update the schedule and explain what remains incomplete. A changed calendar date does not by itself mean that the defined work milestone has happened.

Does an approved estimate prove a payment was made?

No. Approval records the customer's decision about the proposal. Confirm payment from the actual transaction record before reducing the unpaid balance.
