Allowances let you sign a remodel before every tile and faucet is picked. They also cause some of the most common end-of-job billing arguments. Here's how to write them, track them and bill the overage so the final invoice holds no surprises.
01What an allowance is (and what it isn't)
An allowance is a budget placeholder in your contract for something the client hasn't picked yet: tile, plumbing fixtures, a vanity, light fixtures, cabinet hardware, flooring, appliances. You put a number in the contract so you can sign the job before every selection is made, and you agree in writing that the final cost gets adjusted up or down once the client chooses.
That last part is the whole point, and it's where many remodelers get hurt. An allowance is not a promise that the item will cost that amount. It's a starting number with a written rule for what happens when the real number is different.
Allowances let you start a job sooner and give the client a realistic target to shop against. They only work if three things are clear before signing:
- What the number covers. Material only, or material and installation? Tax and delivery included or not?
- When the client has to decide. A selection deadline tied to the schedule, not "whenever."
- How the difference gets handled. Overages billed as a written change order, underages credited, and how markup applies.
If any of those is fuzzy, the allowance turns into an argument at the end of the job. That's one of the most common ways scope creep sneaks in: the client picks a more expensive tile, nobody writes it up, and the difference comes out of your margin.
02Where allowances go wrong
Most allowance problems come from a few repeat mistakes that leave room for two honest people to remember the deal differently.
1. The number is a guess
An allowance set low to make the bid look better almost guarantees an overage conversation later. The client feels like the price went up even though the contract said it might. Set allowances from real quotes or your own recent purchase history for the quality level you discussed, not from the cheapest option on the shelf.
2. Nobody said what it covers
"Tile allowance: $[ ]" is ambiguous. Is that per square foot or total? Field tile only, or trim pieces, setting materials and grout too? Does the installer's labor change if the client picks a small mosaic instead of a large-format tile? If you don't say, the client will assume the most generous reading.
3. No selection deadline
A late selection can hold up the schedule, push back other trades and force rush shipping. If the contract has no date, you have no clean way to address the delay or its cost.
4. Overages handled verbally
The client picks a fixture at the showroom, the supplier bills you, and the overage shows up for the first time on the final invoice. Even with a clear allowance clause, a surprise at the end feels like a bait-and-switch to the client. Every overage should be written up and approved before the item is ordered.
5. Credits forgotten
If the client picks something under the allowance, they expect a credit. Forgetting it, or burying it, damages trust just as much as a surprise charge. Track underages as carefully as overages.
03How to set allowance amounts
There's no universal right number. The goal is an allowance that matches the quality level you and the client actually talked about, so the most likely outcome is a small adjustment rather than a big one.
- Start from the conversation. If the client showed you photos of the look they want, price that look, not a builder-grade stand-in.
- Use current quotes. Ask your supplier for a price range on two or three products at that level. Prices move, so date the quote.
- Decide material-only or installed. Material-only allowances are simpler to track. Installed allowances need a note about what happens if the product changes the labor.
- Say how tax, delivery and markup work. Write whether the allowance amount includes them. If you mark up materials, say whether the markup applies to the allowance and to the overage.
- Show the unit. Per square foot, per fixture or a lump sum. Per-unit allowances are easier for clients to shop against.

04Allowance language for your contract
Your contract should explain allowances in plain words. Here's sample language to bring to your attorney as a starting point. It's an example only, not a finished clause.
If you don't have a change order process yet, start there. Our free change order template gives you a one-page form and the "let me write it up" script that keeps overages from turning into handshake deals.
05The allowance schedule and tracker
Attach an allowance schedule to the contract, then keep the same sheet updated as selections come in. One table, shared with the client, answers "where are we on the budget?" before they have to ask.
Two habits make the tracker work. First, set each "select by" date backward from when the item needs to be on site, with room for lead time. Second, fill in the Actual and CO # columns the day the selection is made, not at the end of the job. The running total is what you show the client in your weekly update. Our client update email template has a spot for it.
06A worked overage example
Here's how the math typically works for a material-only allowance with a markup on overages. Every number below is an example only. Use your own quotes, quantities and markup, and whatever your contract actually says.
Example numbers only. Made-up figures to show the math.
| Line | Example calculation | Example amount |
|---|---|---|
| Floor tile allowance | 60 sf × $6/sf (example allowance) | $360 |
| Client's selection | 60 sf × $11/sf (example price) | $660 |
| Material overage | $660 − $360 | $300 |
| Markup on overage | 15% of $300 (example rate only) | $45 |
| Labor change | Smaller format tile adds 3 hrs × $70 (example) | $210 |
| Change order total | $555 |
Notice the labor line. A client who picks a smaller tile, a heavier fixture or a vanity that needs a different rough-in has changed more than the material cost. If your allowance is material-only, the labor difference belongs on the same change order. For the full line-by-line method, see how to price extra work on a remodel.
The change order would read something like this:
Underages work the same way in reverse: a written change order showing the credit. Whether markup comes off a credit too depends on what your contract says, so decide it up front and write it down.

07Billing the overage
An approved allowance change order is billed like any other change. A few practices many remodelers use:
- Approve before ordering. The cleanest point to approve is when the selection is made, before the item is purchased.
- Bill on the next draw. Add it as its own line with the CO number. Don't hold allowance adjustments for the final invoice, where they pile up into one big surprise.
- Show credits as clearly as charges. A visible credit line builds trust and makes the overage lines easier to accept.
- Keep a running total. The tracker's over/(under) total should match the sum of your allowance change orders.

08How to talk about it with the client
Most allowance fights are really surprise fights. Talk about allowances three times: at the contract signing, when each selection is made and in your weekly update.
At signing, walk the client through the allowance schedule line by line. Something like:
When a selection comes in over, send the number right away, before ordering:
Offering options closer to the allowance isn't a discount. It's giving the client control, which is usually what heads off the argument.

10FAQ
Should I mark up allowance overages?
Many contractors do, because they're buying, handling and warrantying the item. Whatever you decide, say so in the contract and the allowance schedule before the job starts, so it's not a surprise on the change order.
What if the client buys the item themselves?
That's an owner-supplied item, not an allowance. Treat it as a change: credit the allowance and spell out who is responsible for ordering, delivery, damage, returns and warranty on that item. Have your attorney review your owner-supplied items language.
How do allowances affect my job costing?
Track the allowance as its own budget line, then record actual cost and the change order revenue against it. Our job costing guide shows a simple estimate-vs-actual sheet you can use.
