Builder, contractor and commercial countertop pricing: discounts, bids and minimums

Builders, general contractors and commercial customers usually pay less per job than homeowners because they cost the shop less to sell and serve: no showroom visits, repeat layouts, batched templating and installs, and steady volume. Typical trade discounts run 5 to 25% off retail depending on volume, and gross margins on builder work typically land around 25 to 40% against 40 to 50% on retail (2026 U.S. rules of thumb). A discount should never exceed the costs the account really saves, and it should be tied to written volume, payment and scope terms. Commercial jobs are bid from a takeoff with unit prices, and they bring net-30 to net-60 payment, retainage, insurance and bonding costs that must be priced in. Every channel also needs a minimum job charge, typically $300 to $800, because a small job still needs a template trip, machine setup and an install crew.

Why trade customers pay less

A retail kitchen carries costs that a builder kitchen does not. A homeowner may spend 2 to 4 hours with a salesperson before anything is cut, visit the slab yard twice, change their mind about the edge, and call for status updates. A production builder sends a purchase order with a fixed spec: one of four approved colors, one edge, one sink. The shop templates five houses of the same plan in one day, cuts them in a batch and installs them on one route.

Those savings are real, and they are what a trade discount should pay for. Trade work also adds costs that retail work does not:

• Slow payment. Homeowners pay a deposit and the balance at install. Builders and GCs pay net-30 to net-60 after install, and some pay later than their terms.

• Change orders and site problems. Cabinets not ready, walls moved, plans changed after template. Every return trip costs a crew half a day.

• Price pressure at renewal. A price agreed two years ago tends to erode a dollar or two per square foot at each renewal unless contract terms stop it.

• Contract risk. Builder contracts may ask for longer warranties than the stone maker gives, broad indemnification or lien waivers before payment.

• Fewer referrals. The homeowner in a new build knows the builder's name, not yours.

Price trade work so the savings and the extra costs are both visible. A discount that ignores the extra costs is how shops end up busy and broke.

How big should a builder or contractor discount be?

These are rules of thumb, not survey data. You will also hear that builders pay 30 to 50% less than homeowners. That gap is real when you compare a builder-grade kitchen (entry granite, eased edge, one cutout, no tear-out, no sales time) with a retail kitchen in a designer quartz. It is a different product and scope, not a 40% discount on the same job.

The gap is widest on commodity materials, where slab cost is a small share of the price. It is narrowest on premium quartzite and marble, where the slab is most of the price and a percentage discount comes straight out of a small margin.

Calculating the largest discount you can afford

Start from the cost of doing the job for this customer, not your retail cost. Then work out the lowest price that still meets your target margin.

Lowest price = cost / (1 - target margin)

Largest discount = 1 - (lowest price / retail price)

Example: a kitchen that retails for $4,200 costs $2,100 to produce for a builder, with no sales time included. With a 30% target gross margin, the lowest price is $2,100 / 0.70 = $3,000. The largest discount is 1 - (3,000 / 4,200) = 28.6%. A shop that offers 20% keeps some room for change orders and slow payment.

Two refinements:

• Payment terms cost money. If your cost of capital is about 7% a year, carrying an invoice for 60 days costs about 1.2% of it (7% x 60/365). Net-90 costs about 1.7%. Count that in the discount.

• Discount the right part. Material usually carries the most markup and labor the least. A flat percentage off the whole invoice cuts into fabrication and install margin, where there is little room. Many shops set builder prices per material group and per service instead of one blanket percentage, and they never discount resold sinks, faucets or remnants.

How to structure a builder price program

1. Publish a builder price sheet. List material groups by square foot, edges per linear foot, cutouts and holes each, templating, trip fees and a return-trip fee when the site is not ready. Keep an internal version with cost and margin. Send the builder a locked PDF with prices only.

2. Tie tiers to commitments. Give tier pricing for a stated volume, such as a price at 12 units a year, a better one at 24 and another at 36 or more. Add a clause that returns the account to the lower tier if volume falls short.

3. Limit the selection. A builder program with four colors and two edges is cheap to run. Anything outside the list is quoted at retail less a small discount.

4. Control the upgrade sale. Many builders use an allowance and overage model: the base price covers a builder-grade top, and the homebuyer pays for upgrades. Check that the allowance covers your real cost, since builders sometimes set it low on purpose. Where you can, sell upgrades to the homebuyer directly at retail pricing less a modest builder discount, instead of letting the builder buy the upgrade from you at builder rates and mark it up.

5. Put site readiness in writing. Cabinets installed and level within about 1/8 inch, sinks on site, work area heated above about 50°F so adhesives cure, and a trip fee when these are not met.

6. Review every quarter. Track gross margin, average days to payment, re-template rate and change-order rate per account. An account below about 30% gross margin, paying past 60 days or constantly changing plans in the field needs a price change or an exit.

7. Add an escalation clause. Long price locks (6 to 12 months or a whole subdivision) should reopen if slab cost moves more than about 5 to 10%.

Payment terms and protection

• Start new trade accounts on deposits for the first few jobs, then move to terms after a credit application and clean payment history.

• Net-30 is the standard to aim for. Net-45 or net-60 is sometimes the price of a large production account, and it should show up in the discount.

• A late fee, commonly 1.5% a month, is legal in many states. Check yours.

• Protect your lien rights. Many states require a preliminary notice early in the job, such as California's 20-day notice, or you lose the right to file a mechanic's lien. Sign conditional lien waivers, which take effect only when payment clears, not unconditional ones before the money arrives.

• Read for pay-if-paid clauses, which can mean the GC owes you nothing if the owner never pays. Their enforceability varies by state. Have a construction attorney review builder contracts before you sign.

Deposits, change orders and collections are covered in detail in contracts, deposits and payments.

How much builder work is too much?

Builder work is attractive because it fills the schedule. It is dangerous in concentration. Builder volume follows housing starts, and the 2008 crash took down shops that depended on it. Common rules of thumb among fabricators: keep builders to about 40 to 50% of revenue, and keep any single customer under about 15 to 20%. Protect at least one install crew for retail work, and keep collecting reviews from retail customers even when builders keep you busy. See working with builders and contractors.

Pricing apartments and multifamily work

Apartment kitchens are small, typically 15 to 30 sq ft, and they come in batches. Quote per unit, not as one lump sum, so changes in the unit count adjust the price cleanly. Then add the costs that houses do not have:

As a rule of thumb, add $200 to $600 per unit for building logistics. A realistic volume discount on a large run is 10 to 15%, applied where the efficiency really appears, such as the second half of a run of identical units. Phased schedules, such as four or five units a week while tenants move, cost more to run than one continuous push and deserve a premium of about 5 to 10%.

Worked example: a 30 sq ft mid-range quartz unit kitchen costs $1,650 in material, $750 in fabrication labor, $450 in install labor and $350 in logistics, a total of $3,200. At a 40% gross margin the price is $3,200 / 0.60 = $5,333. At 30% it is $4,571. If the local market for such a unit is $4,500 to $5,000, you are bidding at about 30 to 36% margin, which is typical for this work.

Hotel vanities follow the same logic at larger scale: hundreds of identical tops, careful nesting (a 22 x 49 inch top fits four to a 56 x 120 inch slab), tight tolerances across all pieces and a spare rate of about 5% written into the contract.

Bidding commercial projects

Commercial work, such as offices, hotels, healthcare, schools and restaurants, is usually bid to a general contractor from drawings and a spec book. It differs from residential work in four ways: you price from a takeoff (quantities measured off the plans), you submit prices in the GC's format, you get paid slowly, and you carry more risk.

Build the bid from cost

1. Takeoff. Measure square footage by material, linear feet of each edge, backsplash, and every cutout and hole from the drawings. See takeoffs from plans.

2. Material. Get a supplier quote for the exact specified material. Slab quotes are usually valid for about 30 days. Add waste (15 to 30% depending on pattern and matching), freight (often $150 to $400 per slab) and consumables. Landed material often ends up 15 to 20% above the slab invoice.

3. Labor. Budget templating time per room, shop hours and installation. Add payroll burden (taxes, workers' comp, benefits), typically 25 to 35% on top of wages. On federally funded construction contracts over $2,000, the Davis-Bacon Act requires prevailing wages, and many states have their own prevailing wage laws for state-funded work.

4. Overhead. Allocate shop overhead per hour or per square foot. Example: $40,000 of monthly overhead over 800 billable shop hours is $50 per shop hour.

5. Project costs. Mobilization (often two or more trips), after-hours labor, bonds, higher insurance limits and permit fees.

6. Contingency. Add 5 to 10% for inspection risk and unknowns on complex or first-of-a-kind jobs.

7. Margin. Price = total cost / (1 - target margin).

Watch the markup trap here. On $43,000 of total cost, a 35% target margin needs a price of $43,000 / 0.65 = $66,154, which is a 54% markup. Adding 35% to cost gives $58,050, which is only a 26% margin. See margins and markup.

Many shops accept a lower gross margin on large commercial bids than on retail, often 25 to 40%, because the sales cost per square foot is low and one award fills weeks of production. Small commercial jobs are the opposite. A restaurant counter replaced overnight, with health inspection and tight access, carries more risk per square foot than a kitchen remodel and should be priced at or above retail margin plus contingency.

What the GC will ask for

• Unit price schedule. Installed price per square foot by material, per linear foot by edge, per cutout. It lets the GC adjust quantities and compare bids.

• Schedule of values. Your contract amount split into billable parts, for example 30% on material delivery, 50% on installation and 20% at completion and punch list.

• Insurance. Typically general liability of $1 million per occurrence and $2 million aggregate, often more for large projects, with the GC named as additional insured, plus workers' comp and commercial auto. Have your certificate of insurance ready within a day.

• Bonds. Payment and performance bonds are common on public work. On federal construction contracts over $150,000 the Miller Act requires them. Premiums typically run 1 to 3% of the contract for a creditworthy contractor.

• Payment terms. Net-30 to net-60 with 5 to 10% retainage (money held back until the project closes out). A shop can front $50,000 or more in material and labor before the first check. Price the cost of that money and make sure your cash can carry it.

• Submittals. Shop drawings and samples for approval before fabrication, often two or three review rounds. See commercial specifications and submittals.

• Validity and escalation. Keep bid validity to 30 to 60 days and add an escalation clause for phased projects if material cost rises more than 5 to 10% from the contract date.

Restaurants and commercial kitchens

The FDA Food Code, adopted in some form by most states, requires food-contact surfaces to be smooth, durable, nonabsorbent and easily cleanable. Local health departments decide what qualifies. Many accept NSF-certified quartz and solid surface without question, and some want written approval before you install granite, which must stay sealed. Price the extras that residential jobs do not have: after-hours or phased labor (often 25 to 50% more install labor), demolition and disposal in a working building, substrate repair as a not-to-exceed allowance, coved or sealed wall joints, and permits. Accessible service counters must have a portion no higher than 36 inches under the 2010 ADA Standards, and accessible work surfaces sit between 28 and 34 inches. Flag these to the GC; the design team owns them. See commercial countertops.

Setting a minimum job charge

A vanity top and a kitchen need the same template trip, the same saw and CNC setup, the same install truck and the same paperwork. Those fixed costs are why every shop needs a minimum.

Build yours from real numbers. An example per-job fixed cost before material:

Add a share of overhead. A shop with $18,000 of monthly overhead and 40 jobs a month carries $450 per job. With $80 of material, the full cost of a tiny job is about $925, and at a 30% margin the true break-even minimum is about $1,320.

Most independent shops publish minimums between $300 and $800, and often $600 to $1,000 or more in high-cost metros. Many sit below their true full-cost floor on purpose, because small jobs fill gaps in the schedule. Know the gap, and decide it deliberately. Practical guidance:

• Use a dollar minimum, not a square-foot minimum. Customers do not know what a square foot costs you, so "25 sq ft minimum" reads like a phantom charge. "Minimum project fee: $650" reads like a base rate. Call it a fee, not a surcharge.

• Apply it per order, not per room. A kitchen, two vanities and a laundry top on one trip should not trigger four minimums.

• Allow sensible exceptions. A small add-on to a job already booked on the same trip, a shop-pickup remnant piece with no install, or a vanity routed with a nearby kitchen.

• Tier by material if you like. Laminate and solid surface cost less per trip. Natural stone and exotic material warrant a higher minimum, and exotic bookmatched work may be quote-only.

• Disclose it before the customer signs. Put it on the quote.

Where software helps

Trade pricing breaks down when salespeople have to remember which customer gets which rate. In Stonify, pricing tiers such as Retail, Contractor and Designer hold separate prices for every product and service, and a project type such as Builder can default new jobs to the right tier. A builder can carry a standing default discount, while resold sinks and faucets are marked as not discountable. A customer catalog limits a builder's quotes to its approved colors, edges and sinks. For multifamily work, a package multiplier quotes one unit kitchen for twenty identical units, and each builder can have its own invoice template. An early partner feature lets an AI assistant read a builder's PDF purchase order and create a draft quote at the builder's tier for an estimator to check.

FAQ

Should I give a builder the same price on premium material as on builder-grade? No. Premium slabs leave less room for a percentage discount because material is most of the price. Quote upgrades outside the program at retail less a small trade discount.

Is it legal to charge builders less than homeowners? Generally yes for a local fabricator. The federal Robinson-Patman Act mainly concerns selling goods at different prices to competing resellers in interstate commerce. If you sell across state lines to dealers who compete with each other, ask a lawyer.

Does sales tax work the same for builder jobs? Not always. Some states treat a contractor installing countertops in new construction as the taxable consumer of the materials, others tax the sale differently. Check with your state revenue department or accountant before you set up builder billing.

How do I stop builder prices from creeping down? Tie prices to volume tiers and an escalation clause, review margin by account every quarter, and be willing to walk away from an account that stays below your floor.

Should I pay referral fees to contractors? Some shops pay 5 to 10% to contractors who refer homeowners who then buy directly. Put it in writing, and issue a Form 1099-NEC when a contractor's payments reach the IRS reporting threshold, which is $2,000 a year for payments made from 2026 on (it was $600 before).

How long does a commercial countertop project take? Typically 4 to 16 weeks from contract to install, much longer for phased hotels, healthcare and large multifamily. Fabrication is often only 20 to 30% of that time. Procurement, submittals and site readiness take the rest.
