Client Deposit Trust Accounting: Retainers vs Earned Revenue
The most important bookkeeping distinction in event planning — and the one most planners get wrong — is the difference between a client deposit that is yours and one that is not. A refundable deposit is the client’s money held in a trust account. It is a liability on your books: you owe it back unless conditions are met. A non-refundable retainer, paid to secure your services, is earned revenue the moment the client signs — book it immediately.
The reason this matters: booking a refundable deposit as revenue inflates your income, creates a tax liability on money you may have to return, and distorts your actual earnings. A client who puts down a $3,000 deposit in November for a June wedding and cancels in April gets $2,500 back — if you booked that $3,000 as revenue in November, you now have to reverse $2,500 and explain to your accountant why your P&L shows income you never actually kept.
Best practice: Maintain a client trust account (a separate business checking account) for all deposits and retained funds. Deposit all client payments into this account. When an event is confirmed and the deposit is non-refundable or earned, transfer the amount to your operating account as revenue. When a refund is owed, pay it from the trust account. Track every client balance in a sub-ledger so you know at any moment what you owe back versus what you have earned.
Multi-Vendor Payment Management
A single wedding or corporate event can involve 15 to 30 vendors — florist, caterer, photographer, videographer, DJ, officiant, venue, tent rental, linen company, transportation, lighting, hair and makeup, cake baker, invitations and paper, event coordinator assistants. Managing payments to these vendors, many with deposits and final balances at different milestones, is one of the most operationally demanding parts of event planning bookkeeping.
Track every vendor with a vendor payment schedule: deposit amount, deposit date, milestone payments, final balance, and due date. Reconcile this schedule against your bank statements monthly. Vendor payments made from your operating account should be coded to a client-specific project or event code — not just to a generic “vendor” expense category. This allows you to see at a glance what you have spent on a specific event versus what you have collected.
When you pay a vendor and pass the cost through to the client (you pay $800 to the florist, invoice the client for $800), there are two clean accounting approaches. Option one: code the payment as a receivable (DR: Due from Client, CR: Cash) and invoice for reimbursement. Option two: set up the client invoice to include the vendor cost as a pass-through with no markup, coding it as a zero-margin transaction. Either approach works — the key is consistency so your revenue is never inflated by pass-through costs.
Revenue Recognition for Milestone-Based Contracts
Event planners typically structure contracts with multiple payment milestones: a retainer at signing, a deposit at a defined date (often six months out), a progress payment at a mid-point milestone, and a final balance due 30 to 60 days before the event. Each milestone payment has different revenue recognition implications.
A retainer or signing fee that is non-refundable and secures your commitment is earned revenue upon receipt. A progress payment at six months out — before services are rendered — is deferred revenue (a liability) until the event actually happens. Only when the event concludes and your services are complete should those deferred amounts convert to earned revenue on your books.
This matters for tax planning and loan applications. A planner who has collected $18,000 in deposits for events happening in October cannot claim that $18,000 as income in May — it is a liability representing future work. Your accountant needs accurate deferred revenue figures to file correctly, and a lender reviewing your books for a line of credit will see deferred revenue correctly as a liability, not income. If you are preparing to apply for financing, see our post on how clean books help you get a small business loan.
Seasonal Cash Flow Planning
Southern California’s wedding season runs May through October, with peak months June, September, and October. For many event planners, 60% to 70% of annual revenue arrives between May and October, leaving a slow season from November through April. Managing cash flow across this swing is one of the most practical bookkeeping challenges in the industry.
The planning window is September to December. In September and October, you are collecting final balances for that year’s events and receiving new retainer deposits for the following year — historically your highest cash months. November through January is when you can build your operating reserve. That reserve carries you through the slow months when revenue is thin but fixed costs (software subscriptions, insurance, website hosting, advertising) continue.
Build a 12-month cash flow projection in January with realistic revenue estimates by month based on your confirmed and probable pipeline. Identify the low months and plan for them. Event planners who wait until March to figure out cash flow are already behind. A revolving line of credit secured before you need it — when the books look clean and the pipeline is strong — is far easier to obtain than a line of credit you desperately need in February.
Expense timing matters. Schedule larger annual expenses (insurance premiums, software renewals, website hosting) for months when cash is strong. Time equipment purchases for the slow season when you have the capacity to absorb the expense and the tax planning window is open. Section 179 expensing can reduce your tax liability significantly — see our post on small business tax deductions you may be missing for how it applies to event planning equipment and technology.
California Sales Tax on Event Rentals and Equipment
Planning and coordination services are not subject to California sales tax. However, taxable obligations arise when you sell or rent tangible personal property to clients. This includes: tent and equipment rentals where you are the seller of record, décor items sold to clients (floral arrangements, signage, favors, custom printed materials), linen and tabletop rentals, photo booth and entertainment equipment rentals, and any other physical items where you purchase and resell to the client.
Marketplace facilitator rules: If you sell through a platform that facilitates the transaction, the platform may be responsible for collecting and remitting sales tax on your behalf — but this varies by platform and by transaction type. Confirm your obligations based on where your clients are located, as California’s economic nexus thresholds and district tax rules add complexity.
One common trap: a planner who arranges a $12,000 tent rental through a vendor, marks it up to $14,000 for the client, and fails to charge sales tax on the $2,000 markup. The correct treatment: charge tax on the full $14,000, remit the tax to the CDTFA, and keep the $2,000 margin net of tax. Failure to collect and remit sales tax on taxable markup creates personal liability.
1099 Contractor Reporting for Subcontracted Vendors
Event planners frequently hire independent contractors: photographers, DJs, officiants, assistant coordinators, makeup artists, musicians. Under IRS rules, you must issue a Form 1099-NEC to any contractor paid $600 or more in a calendar year for services. Incorporated entities (LLCs filing as C-Corp or S-Corp) do not require a 1099.
Collect W-9s before you pay anyone. Request a completed W-9 from every vendor before you cut a check. Store them in a vendor file. At year-end, you need them to issue 1099s correctly. A vendor you paid $4,200 to without a W-9 on file is a problem at tax time — you either issue the 1099 late or face penalties for missing reporting.
Track all contractor payments in a vendor log: vendor name, amount paid, date, service provided, and whether a 1099 will be issued. This log feeds directly into your year-end 1099 preparation. For the full picture on 1099 obligations, see our post on bookkeeping for contractors and 1099 reporting.
Per-Event Profitability Tracking (Project P&L)
Every event has a P&L — the revenue collected minus the cost of delivering the event, with the margin as the true measure of performance. Many event planners track revenue by client but lose visibility into true profitability because they do not code expenses to specific events.
Create a job code for every event. In your accounting system, set up each client event as a project or class code. Every vendor invoice, every expense, every labor payment gets coded to the event it belongs to. At event completion, run a P&L by event code showing: total revenue collected, vendor costs, sub-contractor payments, direct expenses, and net margin. Over time, this data reveals which event types and which price points are actually profitable — and which are not.
The most common discovery: planners who mark up vendor costs by 15%–20% are often covering less than half of their actual time cost when you account for emails, calls, site visits, coordination, and problem-solving. Project P&L data is the foundation for correct pricing. If you have not been tracking per-event profitability, start now — even one year of retroactively coded data is better than none.
Personal Purchases on Behalf of Clients: Reimbursement vs Pass-Through
Event planners frequently make purchases on behalf of clients — a last-minute floral arrangement, a forgotten card box, a vendor tip, parking validation, or a meal expense while on-site. These are either reimbursable expenses (you pay out of pocket, client reimburses you) or pass-through costs (the client pays you, you pay the vendor).
Reimbursements are not income. If a client sends you $200 to cover a vendor charge you already paid, that $200 is a reimbursement — it offsets the expense you already recorded. It should not appear as revenue. The correct journal entry: DR Cash $200, CR Due from Client (or offset the expense). Do not code reimbursements as income unless you are also marking them up.
Pass-through costs work differently: the client pays you $500, you pay the vendor $500. If you are not marking up the cost, code the client payment as a liability (DR Cash, CR Accounts Payable / Due to Vendor). When you pay the vendor, debit the liability. The net effect on your income statement is zero — as it should be. If you are marking up pass-through costs, the markup is income and must be accounted for properly.
Commingling client funds with operating funds is the main risk here. A separate client trust account (mentioned above) creates a clean boundary: client money in, vendor payments out, reimbursements tracked separately. When everything flows through your personal operating account, reimbursements and pass-throughs blend with earned revenue and create messy books that are difficult to reconcile.
What Well-Run Event Planner Books Look Like
A well-run event planning bookkeeping operation produces: a client trust account with all deposits held correctly and a sub-ledger showing each client’s balance, a vendor payment schedule tracking every payment to every vendor for every event, monthly deferred revenue reconciled so only earned revenue hits the P&L, a 12-month cash flow projection reviewed and updated quarterly, all vendor W-9s on file with a complete 1099-NEC log for year-end, per-event job codes with full P&L reporting at event close, and California sales tax collected and remitted on all taxable items sold to clients.
It also gives the planner a clear view of their true effective rate: what percentage of gross revenue is actually profit after all vendor costs, direct expenses, and overhead. Many planners who think they are earning 20% margins discover on close examination that their effective margin on fully-loaded costs is closer to 8%–12% — which changes the conversation about pricing, client selection, and service offerings.
