The short answer
Urgent work costs you more than the hours it takes, and the difference is real rather than conventional. Price it before you start it, because a rush charge discovered on an invoice is the most reliably queried line in agency billing.
Name the uplift in the contract, so urgency has a published price.
Confirm it in writing when the request arrives, before anyone opens a file.
Price the displacement, not only the hours.
Refuse where the deadline cannot be met properly, rather than hoping.
Never do it free the first time, because the first time sets the price.
Clients ask for urgent work constantly and accept paying for it far more readily than agencies expect. The resistance is almost always on the agency's side.
Why rush costs more than the hours
4 costs, and only the first appears on a timesheet.
Cost | What it is | Who absorbs it by default |
|---|---|---|
The hours | The work itself | Billed as normal |
Displacement | Another client's work moves | You, and sometimes them |
Premium labour | Evenings, weekends, contractors at short notice | You |
Rework | Errors rise when the review step is compressed | You, usually twice |
Displacement is the one that is almost never priced. Taking a rush job means something else slips, and the cost is not the hours you spend but the goodwill, or the overtime, needed to keep the displaced project on track. An agency that accepts a Friday deadline on Wednesday is usually paying for it in 2 places.
The fourth row compounds quietly. Compressed work has a higher error rate, the review step is the first thing cut, and corrections land after delivery where they look like free support rather than like the cost of the rush.
The cost drivers are partly set by law
Premium labour is not a preference, and in several places the ceiling on what you can ask of people is statutory.
In the US, the Fair Labor Standards Act requires that covered, non-exempt employees receive overtime for hours worked over 40 in a workweek, at not less than time and one-half their regular rate. Exemptions exist for certain salaried roles, so whether it applies depends on how your team is classified, but where it does the extra hours cost you 50% more than the standard rate before any margin.
In the EU, the Working Time Directive sets a ceiling rather than a price: the European Agency for Safety and Health at Work summarises Directive 2003/88/EC as requiring that average weekly working time shall not exceed 48 hours.
In the UK, regulation 4 of the Working Time Regulations 1998 provides that a worker's working time, including overtime, shall not exceed an average of 48 hours for each 7 days, measured over a reference period that is generally 17 weeks, unless the worker has given written agreement to opt out.
Which gives the uplift a foundation beyond custom. You are selling capacity that is constrained, more expensive to supply and in some cases legally capped, and that is a defensible thing to charge for.
3 ways to price it
A percentage uplift on the fee for the work, commonly in the range of 25% to 50% depending on how short the notice is. Simplest to explain and simplest to apply.
A premium hourly rate for out-of-hours work, stated separately from your standard rate. Honest where the work is genuinely done at night or at a weekend.
A minimum engagement fee for any request below a stated notice period. Useful where the task is small but the disruption is not, which is most of the time.
Tie the number to notice rather than to effort. Something like: work requested for delivery within 3 business days carries a 35% uplift, and within 1 business day, 50%. That is objective, it needs no argument about how hard something was, and the client can choose the cheaper option by giving you more time, which is the behaviour you actually want.
Agree it before anyone opens a file
A rush charge is queried more than any other line because it is the one the client did not expect and cannot evaluate. The fix is the same as for any extra work: price it when the request arrives, in writing, before starting.
Subject: Re: the deck for Thursday
Hi [Name],
Yes, we can do Thursday.
That is inside our 3-day window, so it carries the 35% uplift we agreed, which on this piece is about [amount]. It also means [other project] moves by 2 days, which I assume is fine but tell me if it is not.
Reply with a yes and I will start this afternoon.
Thanks,
[Name]
Leading with yes is what makes this work. The client came for a deadline, and getting one immediately makes the price a detail rather than an obstacle. Naming the knock-on effect is also worth doing, because it makes the cost visible and occasionally prompts a client to decide the urgency was not real.
Where no uplift was agreed in advance, quote it as a one-off rather than inventing a policy mid-project, and put the policy into the contract at the next opportunity, using the approach in changing a client's terms.
When to refuse
Say no when the deadline cannot be met at acceptable quality, when meeting it would break a commitment to another client, or when the client has a pattern of manufacturing urgency.
The last one deserves attention. Some clients run permanently late and export the consequence to suppliers, and an agency that always absorbs it becomes the place where other people's planning failures are resolved for free. Pricing it is the gentlest available correction; where the price is paid and the pattern continues, that is a client whose rate should reflect it permanently.
Refusing well is short and offers an alternative: we cannot do Thursday properly, we can do Monday, or we can do a reduced version by Thursday. Giving the client a choice between 2 things you can actually deliver is more useful than explaining why the first is impossible.
The first time sets the price
The strongest reason not to absorb a rush is that the second request arrives with the first as precedent. An agency that turned something round over a weekend without mentioning cost has established that weekends are included, and the conversation 3 months later is about a change rather than about a price.
If you want to be generous, be generous visibly. Put the uplift on the quote and discount it to zero, with a line saying so. The client sees the value, the precedent is preserved, and the next one is a normal conversation. That is the same mechanism as giving a discount without repricing the relationship.
On the invoice
Itemise it, name it and date it. A line reading rush uplift, 35%, requested [date] for delivery [date], approved by [name] is almost never questioned, while the same amount folded into the fee invites a query about the total.
That is the general rule for anything a client did not expect, and it is why an itemised invoice survives scrutiny better than a tidy one.
FAQ
How much should I charge for rush work?
A 25% to 50% uplift on the fee is a common range, tied to how short the notice is rather than to how hard the work felt. Stating the tiers in the contract removes the argument entirely.
Why does urgent work cost more than the hours?
Because of displacement, premium labour and rework. Something else slips, the hours may be out-of-hours and more expensive, and compressed work has a higher error rate with the review step compressed first.
Do I have to pay staff more for out-of-hours work?
In the US, covered non-exempt employees must receive at least time and one-half over 40 hours a week, though exemptions apply by role. In the EU and UK there are also ceilings on average weekly hours, so urgent capacity is constrained as well as costlier.
What if I did not agree an uplift in advance?
Quote it as a one-off when the request arrives, before starting, rather than adding it to the invoice afterwards. Then put the policy into the contract at the next renewal.
Should I ever do rush work for free?
Only visibly. Put the uplift on the quote and discount it to zero so the client sees the value and the precedent survives. Absorbing it silently establishes that urgency is free.
How do I turn down an urgent request?
Briefly, with an alternative. Offer a later date or a reduced version by the original date. A choice between 2 things you can deliver is more useful than an explanation of why the first is impossible.
Not legal or employment advice. Overtime entitlements, working time limits and worker classification differ by country and by role. Confirm your obligations before relying on any of the above.
