Giving a discount without giving away margin

A discount comes out of gross profit when direct job costs stay the same. At a 30 percent gross margin, 10 percent off removes a third of the gross-profit dollars, so you need 50 percent more of the same work to earn them back. Calculate that loss before offering a discount, or reduce the scope instead.

How much extra work replaces the lost gross profit

Materials and labor do not get cheaper when you discount. The cut comes out of gross profit, which must still cover overhead before you have net profit.

Extra volume needed to break even = discount % / (gross margin % − discount %)

What 10 percent off demands:

The middle column is measured against the original price, because that is the profit you gave up. Measured the usual way, against the new price, a 30 percent margin reads 22 percent. Same dollars, same break-even.

Use the gross margin from your own books. The table assumes unchanged direct costs per job and enough capacity to do the extra work; overtime or another employee can change the result.

Below your discount percentage there is no math left at all: at a 10 percent margin, 10 percent off leaves nothing to cover overhead.

Example: an $8,000 bathroom before and after a discount

Direct costs — tile, fixtures, subs, your installer's hours — come to $5,600. Gross profit is $2,400, a 30 percent margin. Say the job carries $1,200 of overhead: its share of the truck, insurance, phone, bookkeeping. Pull yours from your P&L.

The price dropped 10 percent and this example's net profit before tax dropped 67 percent. The $800 reduction is fixed; its share of profit depends on overhead. Repeat that same $800 concession three times a month and the annual reduction is $28,800.

Check how a discount affects the taxable amount for your work. First establish whether you collect sales tax on the job at all; materials, labor and who owes the sales tax explains that distinction.

Change the job, not the price

When the budget is real, the honest answer is a smaller job, not the same job for less.

Cut scope in front of them. Standard fixtures instead of the ones they picked; two rooms now, two in the fall. Your rate stays whole and they choose what they give up. A $6,400 job at your full 30 percent margin leaves $1,920 of gross profit for less work — the discounted $7,200 version leaves $1,600 for all of it.

Move the work to a slow month. Deep winter for many trades, high summer or storm season for others — use your own booking history. "I can hold this price if we start the week of March 9" can be useful if the later slot costs you less to fill.

Let payment timing solve it. Some customers want a smaller number today, not less money — a written progress-payment schedule may suit their cash timing.

If you give one, get something for it

A discount is a trade. Name what comes back, in writing:

• A larger deposit, or payment in full at completion instead of net 30
• Permission to photograph the finished work and use the photos
• An introduction to the neighbor with the same problem
• Two more units or rooms bundled into the same trip

Write it in as a line: "Repeat-customer credit, $400 — applied against two units scheduled together." Then it is a term, not a habit.

Do not offer a discount for a Google review. Google's review policy prohibits incentives for reviews of any sentiment and selective requests for positive reviews. The FTC rule separately prohibits incentives conditioned on a positive or negative sentiment; other incentivized reviews still raise disclosure obligations. Ask customers for honest feedback without payment.

When a discount can help fill an unused slot

Schedule certainty. When the calendar three weeks out is thin, a booked job at 20 percent margin beats an empty truck: overhead is paid that week whether the truck moves or not, so anything above direct cost is money you would not otherwise have. That stops the moment the slot would have filled with better work, and it never covers a job priced below direct cost.

Attach the offer to a date, such as "off-season rate for work completed before March 31." Any deposit must fit the applicable rules. For example, California CSLB guidance limits home improvement down payments to the lesser of $1,000 or 10 percent of the contract price, with no exception for special-order materials. Check the rule for your location and type of work.

What to say when they ask you on the spot

Before naming a discount, establish whether the customer needs a lower total or a different payment schedule. Then calculate the option you can afford.

You do not have to say no. You have to not say a number yet.

• "Let me ask first — is it the total that's the problem, or the timing?"
• "That price holds as written. If the budget is firm at $6,500, say so and I'll build you a $6,500 version."
• On a lower bid elsewhere: "Could well be. I don't know what's in their number — want me to walk you through mine?"

In DoneQuote, you can revise the quote's line items when the customer chooses a smaller scope. Describe exactly what remains included and excluded, review the new total and schedule, and obtain approval of the revised work before proceeding.

Summary

• Ten percent off at a 30 percent margin needs 50 percent more volume to break even
• Cut scope, shift the schedule or split the payments before you touch the price
• Trade a discount for a deposit, a referral or photo rights — never for a review
• Never give a number in the moment. Buy one question first

Your price is the outcome of a calculation. Someone asking is not a reason to redo it.
