Accept Crypto Payments as an Interior Designer — Procurement Paid Before You Place the Order

Interior design payments: a thin markup riding on a large pass-through

An interior design studio sells expertise, but most of the money that moves through its account is not its own. The American Society of Interior Designers describes the classic "cost plus" model plainly: the designer buys materials, furnishings and services at cost and sells them to the client at cost plus a specified percentage. ASID also notes the shift of recent years — more studios now charge hourly or a flat fee for the design itself, and cost plus for everything they buy on the client's behalf.

That second part, procurement, is where the volume is. A full-service living room, kitchen and primary suite can mean fifty line items from twenty vendors: upholstery built to order in the client's fabric, case goods, lighting, rugs, window treatments from a workroom, art, freight, receiving and white-glove installation. The client pays the studio; the studio pays everyone else and keeps the markup. On a typical project that sequence repeats for a year or more:

• Retainer at signing, applied to the final balance.
• Design fee — flat, in phases, or hourly and billed monthly.
• Procurement proposals, paid in full or with a 50% deposit before the studio issues a purchase order — because custom pieces are non-cancellable and non-returnable once the vendor starts.
• Balances on delivery, freight and receiving charges, and hourly oversight during installation.

Now run a card through that structure. Take a $60,000 procurement proposal at a 25% markup: the vendors cost $48,000 and the studio earns $12,000. A ~3% card fee applies to the whole $60,000 — about $1,800, or 15% of what the studio actually makes on the order. At a 20% markup, it is 18%. The card network is paid on the sofa maker's revenue; the designer pays it out of their own.

Passing the cost on is harder than it looks. Under Visa's US surcharging rules, a surcharge can't exceed your processing cost or 3%, whichever is lower; it applies to credit cards only, never debit or prepaid; it requires notifying your acquirer at least 30 days in advance and disclosing the fee at every step; and several states prohibit or restrict it. Outside the US, Visa prohibits surcharging with limited exceptions. So most studios end up saying "cards for the design fee, check or wire for procurement" — trading the fee for delay.

What it costs a design studio to leave this unsolved

Start with the deposit that comes back. In March, a client pays an $18,000 card deposit for a custom sectional in their chosen velvet and a walnut dining table. That week you pay the workroom and the furniture maker — both non-cancellable. The pieces arrive in July. In September the client, now mid-divorce or simply unhappy with the shade, disputes the charge as "not as described." You have already paid the vendors, neither will take back a custom piece, and you are arguing with a bank using photos of fabric swatches. Card-network rules can run the clock for delivery disputes from the expected delivery date, not the day the card was charged — so a deposit taken in spring for a 16-week lead time stays exposed well into autumn. If you lose, you are out $18,000 plus a dispute fee, and you own a sofa in a fabric nobody else chose.

Then the cost of avoiding cards. A wire-only procurement policy slows every decision. The client approves a proposal on Monday, their bank releases the wire on Wednesday, it lands on Friday — after the vendor's quote expired, the price rose, or the one-of-a-kind vintage piece sold to another designer. Many studios quietly bridge the gap by paying vendor deposits out of their own cash to protect the schedule, which turns a design firm into its clients' lender.

The clients who could grow the practice fastest feel it most. The National Association of Realtors reports that foreign buyers purchased $45.3 billion of existing US homes between April 2025 and March 2026, with 48% paying all-cash (versus 28% of all buyers), led by buyers from Canada, Mexico, China, India and the UK — and Florida, California and Texas as top destinations. Those buyers furnish from abroad. Every payment they make to your studio is an international wire: days in transit, an intermediary fee that lands the payment short, a truncated reference your bookkeeper has to match by hand. Or it's a foreign card that declines on a $40,000 order and carries higher dispute risk if it doesn't.

Add it up on one mid-sized project — a card fee on the design phase, a week of float on each wired proposal, one reversed deposit, one short-landed wire, one vintage piece lost to a slow approval — and the payment stack is quietly taking a meaningful share of the margin the studio worked a year to earn.

Why card and bank rails fail interior designers

The problem is a mismatch between the money coming in and the money going out. Your outbound commitments are final and time-sensitive: a purchase order for a custom piece can't be pulled back, and a vendor's quote or stock hold won't wait. Your inbound money arrives on rails built for the opposite. Cards are reversible by contract for months and take a percentage of the gross — including the part that was never your revenue. Bank wires are final but slow and expensive across borders, and checks are slower still. Between you and every card payment sits an acquirer that holds funds in transit and can apply a reserve when a single $60,000 transaction looks unusual for a "small business." The studio ends up in the middle, absorbing the risk of both sides. Rails designed for a shopper carrying a lamp out of a store were never built for a business that commits a client's money to a vendor the same afternoon.

How Payzum lets you accept crypto payments as an interior designer

Payzum is a non-custodial, crypto-only payment processor. Non-custodial means the settlement is the payment: when a client pays, the funds route directly to a wallet your studio controls. Payzum never pools, holds or touches the money — so there's no processor balance to freeze, no reserve on a large order, and no acquirer deciding that a $60,000 procurement payment looks suspicious.

The core tool for a design studio is the invoice with expiration and overpayment detection. Each procurement proposal becomes an invoice with a pay-by date you match to the vendor's quote validity: paid in time, you release the purchase order; unpaid, it expires, and you haven't committed a cent. If a client combines two proposals into one payment or sends too much, overpayment detection flags it so the books stay clean. Payments confirm on-chain in seconds — roughly 0.4 s on Solana, about 2 s on Base or Polygon across the supported networks — and they are final. No dispute window, no card percentage on the sofa maker's share.

The rest of the studio's collections run on the same account. Payment links sent by email or WhatsApp close quick approvals — the client says yes to the lamp, you send the link, you order it when it confirms. Hosted checkout or payment buttons sell fixed-price e-design packages and paid consultations to clients anywhere, and a drop-in plugin covers the studio's online shop if you run one. Recurring subscriptions bill monthly design retainers for hospitality, property-management or multi-phase clients. In a showroom or at a design fair, the Payzum POS turns any phone or tablet into a terminal, with a fresh QR per sale and a PIN cashier login for each staff member.

Price stability sits at the settlement layer. Quote in dollars and take payment in USDC or USDT, which are designed to track the dollar one-to-one, so a $60,000 proposal settles as $60,000 of stablecoins. If a client pays in another supported crypto, auto-convert settles it as USDC or USDT. Money also flows out: stablecoin payouts on Polygon, Base, Arbitrum, Optimism, BNB Chain or Avalanche pay installers, the drapery workroom, the freelance drafter or 3D visualizer in another country in a single batch. And signed webhooks can tell your project-management or accounting tool that a proposal is paid, so the purchase order goes out without anyone checking a bank portal.

How it works, step by step

1. Sign up. Create a Payzum account for the studio — no acquirer application, no merchant-category questions about why one client's order is ten times your average ticket.
2. Connect your wallet. Point Payzum at a wallet the studio controls. Every payment settles there directly; turn on auto-convert so everything lands as USDC or USDT, whatever the client paid with.
3. Template your project payments. Create invoice templates for the retainer, design phases and procurement proposals, payment links for approvals and oversight hours, and a hosted checkout for e-design packages. Add PIN cashiers if you have a showroom.
4. Get paid, then order. Send the invoice with the proposal, release the purchase order when the payment confirms — final, non-reversible, and already in your own wallet — and pay your installers and freelancers from the same place when the job is done.

Before the next project kicks off, a short checklist gets the studio ready:

• Match invoice expiry to vendor quote validity, so an unpaid proposal expires before you've committed to a price or a piece.
• Put the payment rail in the letter of agreement: which invoices can be paid in stablecoins, and your refund and cancellation terms for custom orders.
• Turn on auto-convert to USDC or USDT, so every proposal settles at the dollar amount you quoted.
• Send international clients a test link for the retainer, so the first large procurement payment isn't the first time they use it.
• Collect wallet addresses from your installers and freelancers who want to be paid in stablecoins, and prepare the payout batch in advance.

Use cases for an interior design studio, from proposal to installation

The same building blocks cover every way a design practice actually gets paid:

• The second home furnished from abroad: a buyer from Monterrey closes on a condo in Miami and hires you to furnish it before the season. The retainer and design fee go out as invoices; the $64,000 procurement proposal is paid in USDC from their wallet and confirms in seconds. You place every order the same afternoon — no four-day wire, no intermediary fee landing the payment short, no truncated reference to chase. Real estate agencies selling to the same buyers can take payments the same way.
• The custom-order deposit: a sectional in the client's own fabric, a 14-week lead time, a vendor that won't take it back. The deposit is an expiring invoice; once it confirms, it's final. When the piece arrives, there is no "not as described" chargeback in week twenty — if something truly went wrong, you fix it under the terms in your agreement.
• Turnkey furnishing for short-term rentals: an investor furnishes three units at once to a fixed package price. One payment link per unit, paid before you place the orders, and the units are photo-ready on schedule. Vacation rental hosts and managers then collect guest payments on the same rails.
• E-design packages and paid consultations: a fixed-price room design sold through a hosted checkout or payment button, bought by clients in any country — no foreign-card declines, no cross-border card fee, and the design work starts when the payment confirms.
• Showroom, accessories and design fairs: the studio's retail corner or a stand at a design week. Ring up the vase or the throw on a phone, show the QR, and each staff member sells under their own PIN with per-cashier reporting.
• Hospitality and commercial retainers: a boutique hotel or restaurant group that refreshes its spaces every season pays a monthly design retainer as a recurring subscription, with project procurement invoiced separately.
• Paying the people who make it happen: installers, the drapery and upholstery workrooms that accept stablecoins, and the freelance CAD drafter or 3D visualizer working from another country — paid in one batch, straight to their own wallets. See how businesses pay contractors in stablecoins.

Payzum vs cards and wires for interior designers — side by side

Common objections, answered

My clients pay by check and wire — why add crypto?

Run it alongside what works, not instead of it. Stablecoin invoices earn their place where the current rails hurt most: large procurement proposals you'd otherwise take by card, deposits on custom pieces you can't afford to see reversed, and clients abroad whose wires take days and land short. A growing share of international and younger clients already hold dollars as USDC or USDT; for them, paying an invoice from a wallet is simpler than a wire. Everyone else pays as they always have.

My vendors don't take crypto. How do I pay them?

An honest answer: Payzum is crypto-only and settles to your wallet — it does not pay your vendors' bank accounts. Many studios keep part of their balance in stablecoins for the installers, workrooms and freelancers who accept them, and convert the rest when a vendor invoice is due, using an off-ramp they choose. That market is moving quickly, including non-custodial off-ramps that start a bank transfer straight from your own wallet. Talk it through with us before you switch any vendor-facing flow.

Isn't procurement money supposed to be handled carefully?

Yes, and Payzum doesn't change your obligations. It is a payment rail — not an escrow service and not a client-funds account. Settlement lands in a wallet your studio controls; how you hold, account for and refund procurement money follows your letter of agreement and local rules, as does sales tax on the goods you resell. Refunds and cancellations are payments you send from your own wallet under the terms you publish — which is also why those terms should be explicit for custom work.

Is the money safe if Payzum never holds it?

That's precisely what makes it safe. Because Payzum is non-custodial, there's no pooled processor balance to freeze and no reserve to withhold on a large order — payments settle straight to the studio's own wallet. The account is protected with 2FA, signed webhooks and a full audit log.
