A client wires a large deposit. The bank balance jumps. The studio feels healthy. Then vendor deposits, freight, receiving, storage, installation, sales tax, payroll, and refunds start hitting the account.
A month later, the owner asks the question I hear all the time: “How can we be this busy and still feel short on cash?”
The answer is often not weak sales. It is that the bank balance is mixing together money with very different jobs. Some cash has been earned. Some is committed to furniture. Some belongs in a sales-tax reserve. Some may need to be refunded. Some is available for payroll and owner distributions. When all of that sits in one bank account and one report, the owner sees a balance but not the truth.
For a California interior design studio doing roughly $2 million to $10 million in revenue, this is not a basic bookkeeping problem. It is a financial-control problem.
A Design Studio Is Not One Business Model
An interior design studio may operate as several businesses at once:
- A professional service firm
- A project manager
- A procurement operation
- A retailer of furniture and accessories
One generic income account cannot explain those economics.
I want the financial system to separate:
- Design-fee revenue and direct design labor
- Procurement or merchandise revenue
- Product cost and vendor credits
- Freight, receiving, storage, delivery, and installation-related costs
- Sales tax collected and payable
- Client deposits and vendor deposits
- Project-level gross profit by revenue stream
A studio may appear profitable because product markup is covering underpriced design work. Or design fees may be carrying a procurement operation that creates revenue but very little true margin. You cannot price intelligently until the revenue streams are separated.
Use the Four Cash Buckets
I recommend a simple framework called the Four Cash Buckets.
The buckets can be tracked in accounting, a cash forecast, separate bank accounts, or a combination. The important part is that the owner knows what each dollar is expected to do.
1. Earned cash
Cash tied to revenue the studio has actually earned under its contracts and accounting policy.
2. Committed cash
Cash already spoken for – furniture orders, vendor deposits, freight, receiving, storage, installation, and other project obligations.
3. Tax cash
Sales tax, estimated income tax, payroll tax, and other amounts that should not be mentally treated as operating profit.
4. Available cash
Cash that remains after known commitments, near-term operating needs, and required reserves. This is the number the owner can use for hiring, distributions, marketing, or growth decisions. The bank balance alone does not show it.
Markup Is Not Margin
This is one of the most expensive misunderstandings in procurement. Assume a fictional California studio buys a sofa for $10,000 and adds a 30% markup. The client price becomes $13,000. That is not a 30% gross margin. Before other costs, the margin is about 23.1%.
Now add:
- $900 of freight.
- $450 of receiving.
- $390 of card fees.
- $600 of staff time.
The full landed and handling cost is $12,340. The item produces only $660 before overhead, about a 5.1% margin, unless some costs are billed separately. The lesson is not that 30% markup is always wrong. The lesson is that markup does not answer the question the owner actually cares about.
I want to see client revenue minus product cost, freight, receiving, storage, delivery, card fees, damage, credits, and direct staff time. Anything less is partial margin.
California Sales Tax Requires More Than a Taxable Checkbox
Sales of tangible goods such as furniture and accessories are generally taxable in California. Professional design services may be nontaxable when they are not directly related to the sale of goods. Charges directly related to acquiring and providing the goods may be included in taxable gross receipts.
The contract, facts, and invoice structure matter. Calling a charge a “design fee” does not automatically make it nontaxable when the work is directly tied to the merchandise sale.
When a studio pays sales tax on an item and later resells it before use, a tax-paid-purchases-resold deduction may be available when properly reported. That is not the same as ignoring tax on the client sale. The bookkeeping must preserve enough detail to support the position taken on the sales-tax return.
Client Deposits Are Not Automatic Profit
A client deposit may need to fund:
- Future design work
- Furniture and accessories
- Freight and receiving
- Installation
- Sales tax
- A possible refund
For management reporting, do not automatically treat every deposit as available income.Vendor deposits also need a clear trail. Tie each deposit to the vendor, purchase order, client project, expected delivery, and remaining balance. Expensing a large vendor deposit immediately can make one month look terrible and the next month look artificially strong.
The owner needs a project cash view showing:
- Cash received
- Cash committed
- Cash spent
- Cash still collectible
- Expected project margin
A $3.8 Million Studio Example
Consider a fictional California design studio doing $3.8 million in annual revenue. The bank account shows $610,000 after several client deposits arrive. The owner considers a $120,000 distribution and a new senior hire.
The Four Cash Buckets reveal:
- $280,000 is committed to open purchase orders and vendor deposits.
- $58,000 should remain reserved for sales tax and payroll obligations.
- $105,000 is needed for the next six weeks of payroll and operating costs.
- $72,000 relates to projects with unresolved delivery or refund exposure.
The truly available amount is far below the bank balance. The distribution and hire may still happen. But the timing and amount should be based on available cash, not visible cash. That is financial control.
The Procurement Control Loop
The books should follow the actual project workflow:
- Client deposit received: Identify the portion expected for goods, services, tax, and possible refund.
- Purchase order approved: Tie vendor, item, client, markup, tax treatment, and expected margin.
- Vendor deposit paid: Track the prepaid amount by project and purchase order.
- Goods received: Capture damage, shortages, credits, freight, receiving, and storage.
- Client billed: Separate taxable goods, related charges, and professional services based on the facts.
- Sales-tax return prepared: Reconcile taxable sales, tax collected, and adjustments to invoices and the general ledger.
- Project closed: Confirm vendor balances, client balances, final margin, and cash released from commitments.
The process does not end when the item is ordered. It ends when the client invoice, vendor account, project report, books, and tax records agree.
The Bigger Reframe
You may think you need a better bookkeeper. What you may actually need is a financial system designed for a hybrid service-and-procurement business. The issue is not whether the transactions are entered. The issue is whether the owner can see true procurement margin, committed cash, tax exposure, and distribution capacity before making decisions.
Bottom Line
The bank balance is not lying because the bank is wrong. It is lying because one number is being asked to represent earned cash, committed cash, tax cash, and available cash at the same time.
Separate the buckets. Measure full landed margin. Connect procurement, accounting, tax, and cash forecasting. Then the owner can make decisions without guessing.
Frequently Asked Questions
Do California interior designers charge sales tax on furniture? Sales of tangible goods are generally taxable. The treatment of related service charges depends on how closely the services are connected to the sale of goods and how the agreement is structured.
What if the studio paid sales tax when buying an item for resale? A tax-paid-purchases-resold deduction may be available when the property is resold before use and the transaction is reported correctly.
Should client deposits be recorded as income immediately? Not automatically. Management reporting should distinguish cash received from revenue earned. Tax and financial-statement treatment depends on the contract, facts, and accounting method.
How should vendor deposits be tracked? They are commonly tracked as project-specific prepaid amounts tied to the vendor, purchase order, and expected delivery until the transaction is completed under the studio’s accounting policy.
When should a design studio outsource its accounting? The trigger is complexity. Multiple projects, procurement, deposits, sales tax, staffing, and owner distributions are strong signs that the studio needs a dedicated financial system rather than occasional bookkeeping help.
