Interior design doesn’t run like any other business, and the way you earn, spend, and reclaim VAT needs an accountant for interior designers who understands the difference.
Key Takeaways
- A specialist accountant understands how design income and procurement actually work, where a general accountant tends to miss both.
- Project income is recognised against milestones, not cash received, so your accounts reflect what you have truly earned.
- You must register for VAT once turnover passes £90,000 over any rolling 12-month period, and can deregister below £88,000.
- When you resell furniture and materials, you account for VAT on your full markup, not just your design fee.
- Designers routinely underclaim allowable expenses like samples, design software, and showroom travel that a specialist always checks for.
- A trade account unlocks wholesale pricing and supplier credit, and clean books make the application far smoother.

1. Why interior designers need a specialist accountant
A general accountant treats your business like any other.
Interior design isn’t like any other business, and that mismatch costs you money. Here’s what a non-specialist tends to miss:
- Your income arrives in lumps tied to project milestones, not steady monthly pay
- Your costs include thousands of pounds of furniture you buy on a client’s behalf
- Your VAT position shifts depending on whether you’re charging a design fee or reselling a product
A specialist accountant for interior designers starts from how your practice really earns and spends, then builds your bookkeeping, tax planning, and structure around that
The payoff is cleaner books, fewer surprises at year end, and a tax bill that reflects every relief and expense you’re owed.
2. The financial challenges unique to interior design businesses
Interior design throws up money problems that off-the-shelf accounting advice simply doesn’t address.
Project-based revenue and milestone billing
Most design projects span months and pay out in stages:
- a deposit
- a procurement drawdown
- a completion balance.
That makes revenue recognition genuinely tricky, because the cash hitting your account in a given month rarely matches the profit you’ve actually earned on the work.
Procurement, trade discounts and supplier commissions
When you buy furniture and materials for a client, you’re often buying at trade prices and reselling at retail or charging a markup… and that margin has to be accounted for correctly.
Layer in supplier commissions and trade discounts, and the picture gets complicated fast.
- Are you disclosing the markup to your client?
- Is the commission income being recorded?
These choices affect your VAT, your profit reporting, and your professional transparency, too.
The feast-or-famine cash flow cycle
Project income is lumpy by nature.
A strong quarter can be followed by a quiet one while you wait for the next contract to sign, yet your studio rent, software subscriptions, and any staff costs roll on regardless.
Without forecasting, that rhythm turns into stress and sometimes into borrowing you didn’t need. Good cash flow planning maps your expected project pipeline against your fixed costs, so the quiet months are anticipated rather than survived.
3. How VAT works on design services and procurement
VAT is the area where interior designers lose the most money to confusion, because design work and product resale are treated differently.
You must register for VAT once your taxable turnover passes £90,000 over any rolling 12-month period, and you can deregister if it falls below £88,000. For a growing studio that threshold arrives quietly, often mid-project, so it pays to watch it.
VAT on your design fees
Your design and consultancy fees are standard-rated at 20% once you’re registered.
That’s the straightforward part: you charge VAT on what you invoice for your time and expertise, and you reclaim VAT on the costs of running your practice.
The complexity starts when products enter the picture.
VAT on furniture and materials you resell
When you buy goods for a client and resell them, you generally reclaim the VAT you paid your supplier and charge VAT on the price you bill your client: meaning you account for VAT on your full markup, not just your fee.
Whether you treat procurement as a disbursement (passed on at cost with no markup) or as a resale (bought and sold as your own supply) changes the VAT treatment entirely.
4. Expenses interior designers can claim
Designers routinely underclaim because their costs don’t look like a typical business’s costs – but many of them are fully allowable. The list below covers the deductions specific to design work that an accountant who knows the sector will always check for.
- Sample materials and mood-board supplies: fabric swatches, paint samples, finishes, and the physical materials you use to present concepts
- Design software: CAD, rendering, and project-management subscriptions
- Showroom visits and trade-show attendance: including travel and entry costs where the purpose is sourcing or professional development
- Travel to client sites and suppliers: mileage or fares for project-related journeys
- Professional subscriptions and memberships: industry bodies and trade associations
- Marketing and portfolio costs: photography of finished projects, website, and promotional material
- Use of home as office: a proportion of household costs where you work or design from home
- Professional indemnity insurance: cover specific to design and specification work
5. Choosing the right business structure
Whether you trade as a sole trader or a limited company affects your tax, your liability, and how you draw income.
Trading as a sole trader
As a sole trader you keep things simple: one Self Assessment return, full personal liability, and tax on all your profits at income tax rates.
It’s the lightest option to run, which makes it the natural starting point for most new design practices… but that simplicity comes with no separation between you and the business.
Trading as a limited company
Incorporating as a limited company introduces more admin but opens up more efficient ways to draw income_ a mix of salary and dividends. It also caps your personal liability, which matters when you’re committing to large procurement orders on a client’s behalf.
As your practice takes on bigger projects and more financial risk, that protection often becomes the deciding factor on its own.
Knowing when to make the switch
The crossover point is usually about profit level and how much you reinvest, and it’s a calculation worth running properly rather than guessing.
A specialist models both scenarios against your actual figures and tells you when incorporating starts to pay – so you switch at the right moment, not too early or too late.
Note: The crossover point is a real calculation, and our sole trader vs limited company comparison breaks down the tax implications in detail.
6. How to get a trade account as an interior designer
A trade account gives you access to wholesale pricing and credit terms with suppliers – a core part of running a profitable design business. Here’s how to set one up and what suppliers expect.
- Register your business properly: most suppliers want a registered business name, and many ask for a company number or proof of self-employment
- Prepare proof of trading: a business bank account, a website or portfolio, and sometimes examples of completed work
- Provide VAT details if registered: having a VAT number can speed approval and is often expected by larger suppliers
- Apply directly to each supplier: trade accounts are granted per supplier, each with its own credit check and terms
- Manage the credit carefully: trade accounts often come with payment terms, so track what’s owed against your project cash flow
Clean, well-organised accounts make trade applications far smoother, because suppliers extending credit want to see a business that’s run properly. This is another point where having your books in order pays off directly.
7. What to look for in an accountant for your design practice
Not every accountant who says “we work with creatives” actually understands design, so it’s worth knowing what genuine specialism looks like before you commit.
Look for an accountant who:
- Talks fluently about procurement VAT, project-based revenue, and creative tax reliefs without you having to explain them first
- Can tell you how they’d handle the markup on a furniture order, or when they’d suggest incorporating – the quality of the answer tells you everything
- Is proactive about cash flow and deadlines rather than reactive at year end
- Treats your creative work as the serious business it is
At WallsMan Creative, this is precisely the work we do.
As ACA/ACCA-led accountants specialising in the UK’s creative sector, we understand how interior design businesses earn, spend, and grow: from project billing and procurement VAT to the reliefs most firms overlook.
If you’d like an accountant who already speaks the language of design, we’d be glad to talk.
