Hourly rate changes: 3 notice rules for projects

To change your hourly rate mid-project, tell the client before billing, write down the new terms, and seek agreement before adding work.

Key takeaways

State the new rate and when it starts.
List each added expense with its amount and reason.
Ask for a clear yes before doing extra work.

The work is already moving, the client has a budget in mind, and it is not obvious whether a short email is enough or whether you owe a fuller explanation. Lawyers deal with a version of the same problem, and some of the rules that govern their fees are published online. This post takes three notice rules from those published rules and turns them into habits you can use when you need to raise a rate or add a cost after the work has begun.

Read this as a model, not as legal advice. Each quote here comes from a rule for lawyers in one specific place. Utah's rule covers lawyers in Utah, and the D.C. Bar's page covers the D.C. rules of professional conduct. For freelancers, designers, consultants, and other trades, these are communication habits rather than statements of legal requirements. If a dispute could turn on your contract's wording, talk with a lawyer in your own state or country.

Why lawyers' rules make a useful model

The rules quoted here are useful because they are written down, public, and specific about how fee terms and the scope of work must be communicated to a client. They make a handy checklist even for someone who is not a lawyer. The questions they answer are the questions a freelancer faces: who needs to hear about the change, how it should reach them, and what limits apply when the price or the work changes.

The three rules below come from two sources. The first is Utah's rule on fees and expenses. The second is the D.C. Bar's page on the scope of representation, which sets out the D.C. rules on that subject. Each rule is labeled with its place of origin. Advice that is not drawn from either source is marked as my own.

Notice rule one: tell the client about every rate change

The Utah rule says that "any changes in the basis or rate of the fee or expenses shall also be communicated to the client." The sentence is short and has one clear job: the client must be told. It covers changes to expenses as well as to the fee.

For a freelancer, the practical reading is simple. The client should hear about the new rate from you, directly and in your own words, before they see it on an invoice. A new rate that first appears on an invoice means the client learns of the change only when they are being asked to pay for it. A notice gives them a chance to ask questions, push back, or plan around the change before money is due.

The same Utah rule has a sentence about starting terms. It says the scope of the representation and the basis or rate of the fee "shall be communicated to the client, preferably in writing, before or within a reasonable time after commencing the representation." That sentence is about the start of the work, not changes later in it. Writing a later change down is my practical recommendation.

Keep the message short. Say what is changing, the new rate, the day it takes effect, and the reason in one sentence. Then invite questions and stop. A long apology or a pile of justifications can make a simple change look like a negotiation you did not mean to start.

Consider two ways of raising a rate on a project partway through. In the first, the new rate appears on the next invoice with no comment. In the second, you send a note before the new rate starts. It names the rate, the start date, and the reason, and asks whether the client has questions about the timeline. Both change the same number. Only the second tells the client what is happening before they have to react.

Notice rule two: write the change down and name every expense

The Utah rule says that "the agreement must clearly notify the client of any expenses for which the client will be liable whether or not the client is the prevailing party." That sentence is about lawyers' agreements, and "prevailing party" is a term about who wins a dispute, so it has a legal setting a freelancer's notice does not need. The part that carries over is clarity: the client should be able to see, in writing, which expenses they will owe.

For a freelancer, that means listing each added cost on its own line with the item, the amount, and the reason. If you are adding a software license, a travel charge, a stock asset, or a fee paid to a third party, name it. Vague wording such as "some additional costs may apply" leaves the client guessing. A line-by-line list lets them check each item against what they agreed to and question one item without reopening the whole project.

The D.C. Bar's page also speaks to writing. It says that "it is generally prudent for the lawyer to explain in writing any limits on the objectives or scope of the lawyer's services." That is advice about lawyers and limits on scope. My recommendation for freelancers is similar: if a rate increase or new cost also changes what you will deliver, write the new limits down along with the new price.

A written change also protects both sides. If the client later remembers the old rate or the old scope, the notice shows what was said and when. Keep a copy in the project folder beside the original agreement, so the two can be read together. For the signing stage, see the guide to signing and timing checks.

Separate the rate change from any expense change when you can. A new hourly rate and a new reimbursable cost are two decisions. Bundled into one message, they can feel like accept-both-or-reject-both. Two short items, each with its own reason, let the client agree to one and question the other.

The Utah rule says a lawyer "shall not make an agreement for, charge, or collect an unreasonable fee or an unreasonable amount for expenses." It adds that the factors it lists, in (a)(1) through (a)(8), "are not exclusive." A checklist of factors is therefore not the whole test.

Before sending a new rate, ask a few questions. These are my suggestions, not legal tests. Does the new rate reflect a real change, such as more skill needed, a longer timeline, or more risk to you? Can you explain that change in one sentence the client would understand? Would you accept the same change if the roles were reversed? If the honest answer to the last question is no, rethink before you send it.

The D.C. text distinguishes reasonable scope limitations requiring informed consent from the broader duty to consult with clients about how their objectives will be pursued.

If your added cost also changes the work, treat it as a scope change. Propose it in writing, give the reason, and describe what the client gets for the extra money. Then wait for a clear yes before starting the extra work. A reply of "sounds fine" to a vague message is weaker than a reply that names the new cost and scope.

Be careful with "reasonable." It is easy to decide a rate increase is reasonable because you need it. The client sees the same change from their side, with their own budget and plans. A notice is what turns a surprise into a decision the client can actually make.

Illustrative example: adding a cost mid-project

Suppose a client asks for a second round of revisions outside the original scope, and the project now needs a font license you must buy. Illustratively, the license costs 10. The first rule means the client hears about both changes from you before the next invoice arrives. The second rule means your written message names the font license, with its amount and reason, on its own line. The third habit is to consider whether the extra revision round is reasonable and wait for a clear yes before doing that work.

State the new rate if it is changing. List the license as its own line item. Describe the added revision round as a scope change, and say you will start it only after the client agrees in writing.

How much notice should you give?

Choose a notice period that lets the client consider the change before it starts. The Utah phrase "a reasonable time" is tied to the start of the representation, not to changes made later in the work.

Give the client enough time to decide whether to keep going at the new rate, adjust their budget, or talk about scope. A client on a fixed budget may need more time than one with a flexible budget. State the start date so there is no doubt when the new rate applies, and avoid starting it on the same day you first mention it unless the change is small and already agreed.

If the work has a natural break point, such as the end of a phase or a billing cycle, consider starting the new rate there. A change that begins at a clear boundary is easier to explain and check later. Name that boundary in the message so the client can see which work the new rate covers. For ongoing billing, also review recurring invoice dates.

A message you can adapt

Fill every bracket before you send it, and delete any line that does not apply.

> Hi [client name], > > As we move into [next phase or month], I want to let you know about a change to my rate. Starting [date], my rate for this project will be [new rate] per hour, up from [old rate]. > > The reason is [one clear sentence]. The new rate applies to work from [date] onward. Work completed before that date stays at [old rate]. > > I also need to pass through the following costs: > > - [item]: [amount], [reason] > - [item]: [amount], [reason] > > If this change does not work for you, let me know by [date] and we can talk through the options, including changes to scope. > > Thanks, > [your name]

Read the finished message as if you were the client. Check that the new rate, the start date, and each expense are stated once and clearly. If anything is uncertain, such as the amount of a cost, do not send it yet. A notice with a missing number invites the very questions it was meant to prevent.

What to do if the client pushes back

Answer the specific question and point back to the written notice rather than repeating the whole argument. If the client asks why now, point to the start date and the work the new rate covers. If they ask why this much, point to the one-sentence reason and the listed costs. If they ask whether the old rate can stay, say what you can offer, such as a change to scope, and say plainly what the new rate still covers. If the honest answer is no, say so without burying it in a longer message.

If the client needs time, give it to them in writing and set a date to talk again. Keep every exchange in the same written thread so the record stays in one place.

Checklist before you send a new rate

The change is stated plainly, with the new rate or cost and the date it takes effect.
The client hears about it from you directly, before they see it on an invoice.
Every added expense is on its own line with its amount and reason.
The reason is one sentence you could say to the client's face.
The change is one you would accept if the roles were reversed.
If the change also changes the work, you have asked for a clear yes before doing the extra work.
You have said what happens next if the client does not agree.

Today, read your original agreement beside a draft notice and check that the proposed rate, start date, expenses, and scope match what you intend to offer.

Questions about changing your rate

Does this guidance establish legal requirements for freelancers?

No, these are communication recommendations modeled on rules for lawyers. Your own contract, the law where you work, and your client's terms may say more. Some may set a notice period, a method for sending notice, or a process for changing a rate. If this post and your contract disagree, follow the contract and ask a lawyer in your area what it means.

Can you start extra work while waiting for agreement?

Wait for a clear yes before starting the proposed extra work. If the client replies with a question rather than a yes, answer it and keep the work paused until the answer is clear.
