How to write an architect invoice

What goes on a architect invoice

Six things, in the order they belong on the page. The invoice generator opens a architect document with the lines already in place, so most of this is checking rather than typing.

1. Invoice against a named work stage. Concept design complete, developed design complete. The stage is the deliverable.
2. Show the fee basis on every invoice. A percentage of construction cost, a fixed stage fee, or hourly, restated each time.
3. List what the stage produced. Drawings, schedules, the planning submission. It is the evidence behind the claim.
4. Charge additional services separately. Anything outside the agreed scope is not inside the percentage.
5. Show disbursements at cost with the item named. Planning fees, printing, surveys and searches are not your fee.
6. State the fee remaining and the stages ahead. It makes a staged fee feel like a plan rather than a series of demands.

The lines a architect invoice usually carries

These are the lines the generator opens with when you pick Architect. The figures are a starting point to type over rather than a going rate: this site runs no pricing survey, and the number on your invoice should be the one you charge.

Add, rename, reorder or delete any line, and set tax per line where it applies. Priced as they open, that comes to $6,480 before tax.

A worked architect invoice, filled in

This is the same job as the table above, written out the way it would leave your phone. Every figure on it is a starting point rather than a going rate, and the tax line is shown at ten per cent purely so the arithmetic is visible: set your own rate, or none, per line.

Subtotal $6,480, tax $648, total $7,128. The parts worth copying are the structure rather than the numbers: the job reference next to the client, every line separately priced with its count showing, the tax on its own line, and terms that name a number of days instead of saying on receipt.

Percentage fees, fixed fees and restating the basis every time

A percentage fee is agreed once and then invoiced five or six times over a year or more, by which point the client frequently no longer remembers how it was calculated.

Restate the basis on every invoice: the total fee, the percentage or fixed sum it derives from, the stage being claimed, the amount claimed and the balance remaining. It costs three lines and removes almost every fee query.

Where the fee is a percentage of construction cost and that cost has moved, address it on the invoice at the time rather than at the end. A client who sees the recalculation once at final account will treat it as a surprise, and they are right to.

Scope, additional services and the client who keeps changing their mind

Design changes after a stage is signed off are the defining commercial problem in architectural practice, because the work is real, the client rarely perceives it as new, and it is invisible in a percentage fee.

Handle it the way the profession does: define additional services in the appointment, then invoice them as their own lines with the instruction that caused them named and dated. Redesign following client instruction to relocate the stair, with the date, is a fact. Extra design work is an opinion.

The same applies to reworking after a planning refusal or a change in the brief. Neither is inside a stage fee, and both need to be raised as an additional service before the work rather than as a line on an invoice afterwards.

Disbursements, expenses and the money that is not your fee

Planning application fees, building control charges, printing, surveys, structural input and travel are pass-through costs, and clients resent them when they arrive folded into a fee.

Show them at cost, itemized, with the payee named where it is a statutory fee. If you apply a handling charge on disbursements, state it as a separate percentage line rather than marking the item up quietly.

Keep them on the invoice they belong to rather than accumulating them for the final claim. A planning fee appearing eight months after submission is a query that costs you more time than the fee is worth.

Hourly, fixed price or per unit: how architects price the work

Architectural fees are a percentage of construction cost, a fixed fee per stage, or hourly for additional services, and most appointments use all three at once. The invoice is a claim that a stage is complete rather than a bill for hours.

Restate the fee basis on every invoice: the total, the stage claimed, what it produced, and the balance remaining. An appointment signed a year ago is a document nobody rereads, and three lines on the invoice remove almost every fee query.

Working out what to charge

This guide is about what goes on the document, not what the number should be, and nobody should hand you a rate for your own market. What the site can do is the arithmetic: the freelance rate calculator works back from what you need to earn, the service price calculator prices a service against your costs, and the profit margin calculator checks what is left once the job is done.

Writing it on your phone, in five steps

Most architects write the invoice standing next to the work rather than at a desk a week later, and the week later version is the one that gets details wrong. The generator is built for the first case.

1. Open it with your trade already chosen. The architect invoice loads with concept design stage and the rest of the lines already on the page.
2. Put the client and the job reference in first. It is the part you will not remember accurately in three days, and on agent, landlord or contractor work it is the reason the invoice gets paid at all.
3. Edit the lines rather than starting from empty. Change the quantities and the rates, delete what you did not do, add what you did. Keeping the descriptions means the wording stays consistent from one job to the next.
4. Set the terms to 30 days and add a payment link. A due date that is an actual date gets chased. A link and a QR code means it can be settled before you have packed up.
5. Send it before you leave. The clock on your terms starts when the invoice arrives, not when the work finished, so every day it sits unsent is a day added to getting paid.

Getting paid once it is sent

Put a due date and your terms on the document, because an invoice without them is hard to chase. Add a payment link and a QR so settling up is a tap rather than a transfer somebody has to set up. When part of it lands, the receipt maker records it as a part payment and prints the balance still due. If the due date passes, the late fee calculator works out what your own terms allow and writes the chasing letter to go with it.

Five dates decide whether a architect gets paid on time, and four of them are set before the work starts.

Mistakes that cost architects money

• Invoicing without naming the stage. The client cannot tell what they are being asked to pay for.
• Fee basis stated only in the appointment. Nobody rereads an appointment letter twelve months in.
• Additional services never invoiced. The most common cause of an unprofitable project in practice.
• Disbursements marked up silently. A small margin that costs a large amount of trust.
• No balance remaining shown. Each invoice feels like a new demand rather than part of a plan.
