Event companies are cash-rich and margin-blind by default. Client money arrives months before delivery, so the bank account always looks healthy; costs land in a compressed burst around each event, so the P&L swings wildly month to month; and somewhere between the two, a business that never separated deposits from earnings discovers it has been paying for March’s conference with June’s wedding money. That drift, spending event B’s deposit on event A’s costs, is the industry’s signature failure, and it is a bookkeeping failure before it is anything else. This guide covers the deposit architecture, the principal-versus-agent decisions that decide what revenue even is, crew payments, and the per-event reporting that makes an events business manageable when outsourced finance services run the rhythm rather than the owner’s inbox.

The foundational entry: client money received before delivery is unearned revenue, a liability, held per event, released to income when the event is delivered. A $60,000 conference contract with $30,000 paid on signing is not $30,000 of income in the month of signing; it is a $30,000 obligation to deliver, sitting on the balance sheet next to the cash that funds it.
The management discipline that follows is the one that keeps event companies solvent: each event’s deposits map to that event’s committed costs. The working tool is a per-event schedule, deposits received and due, against supplier commitments made, venue, AV, catering, talent, crew, so at any moment the business can answer the only question that matters in this model: if every contracted event proceeded, does the cash on hand plus contracted receipts cover the committed costs? A company whose unearned revenue balance exceeds its bank balance has already spent client money it has not earned, and knows it the day it happens rather than the month a big event’s bills arrive. Deposits paid out to suppliers, the venue’s holding deposit, the AV bond, are the mirror image: prepayments, assets per event, tracked to recovery or application.
GST needs one deliberate decision here: most event “deposits” are part-payments of the contract price, attracting GST on the normal attribution rules when invoiced or received, not security deposits under the special rules that defer GST until a deposit is applied or forfeited. Classify what your contracts actually create, invoice accordingly, and the BAS follows; misclassifying part-payments as security deposits understates GST in exactly the periods the cash arrived. Use a simplified BAS calculator only after the coding is clean, because a calculator cannot fix a deposit treated as income.
An events operator holds $420,000 in the bank and $510,000 of unearned event deposits across 18 future jobs. Supplier deposits paid out total $65,000. On a cash-equals-available view the business looks flush. On a deposit-liability view it is already $155,000 short of funding committed delivery if every job proceeds and no further client money arrives. That gap is exactly what quiet months hide until a large June conference’s supplier invoices land and the August wedding deposits have already been spent on March shortfalls. The weekly control is simple: bank balance plus contracted receipts due, minus unearned deposits’ committed costs, must stay positive, event by event and in aggregate.
Event companies buy venues, catering, AV and talent on behalf of clients, and every such line carries a structural question: is the company acting as principal, buying the service and reselling it, revenue at gross, cost of sales beneath, GST on the full amount charged, or as agent, arranging the client’s own purchase, revenue at the fee or commission only, with the pass-through outside the company’s revenue and its GST handled per the agency?
The answer is set by the contracts and the conduct, who bears the risk, who sets the price, whose name is on the supplier arrangement, not by preference, and it changes the reported revenue of the business by multiples. A company managing $4 million of client event spend for $800,000 of fees is a $4 million business as principal and an $800,000 business as agent, with different GST mechanics, different margin optics for lenders, and different exposure when a supplier fails. The bookkeeping requirements: decide the position per revenue line, in the engagement terms, document it, code consistently, and invoice in the form the position requires, management fees separated from recharged costs where acting as agent, single gross billing where principal. Mixed models are fine and common, venue as agent, AV as principal, production management as fee, provided the ledger reflects the mix rather than an accident of who typed the invoice. The same structural question appears across agencies generally; accounting for pass-through costs and client recharges is the deeper reference on agent versus principal GST and P&L shape.
Marked-up pass-throughs deserve honest internal visibility even where the client sees one number: the margin report should show fee income and procurement margin separately, because they are different businesses, one sold on expertise, one on buying power, and pricing decisions need both visible.
For each major cost category (venue, catering, AV, talent, staffing), answer four questions in the contract and the invoice form. Who contracts with the supplier? Who can change the specification and price? Who bears the loss if the supplier fails or overcharges? Does the client invoice show a gross package or a fee plus disclosed recharges? If the answers point both ways, pick one model deliberately and write it into the engagement letter; ambiguity is how BAS, lender packs and sale diligence all get restated later.
Delivery runs on surge labour, riggers, technicians, ushers, coordinators, engaged as casuals under the relevant award for the work, with weekend, evening and long-shift patterns making penalty and overtime configuration the payroll centre of gravity, or as contractors, where the two standing tests apply with full force. Individual crew paid hourly for their personal labour sit squarely in the superannuation extended definition regardless of ABNs, and the payroll tax relevant contract provisions examine the same arrangements independently; crew supplied through genuine labour hire or production companies sit outside both, at the cost of the supplier’s margin. The industry’s habit of same-week engagement and payment makes the onboarding discipline, classification or contract decided and documented before the event, not after, the difference between a clean file and a retrospective assessment, and the per-payday superannuation clock now runs across exactly this kind of high-churn casual workforce. Run the numbers on contractor versus employee cost before assuming ABN invoices are cheaper than employment.
Cost every crew hour to its event at the loaded rate, wages plus loadings, super and on-costs, because crew is usually the largest controllable cost line and the first place an event’s margin leaks.
A two-day conference budgeted $28,000 of crew at base rates. Actual delivery used evening bump-in, a public-holiday pack-down and six last-minute casuals. Loaded cost lands at $37,500. The event still looks fine on a cash bank view because the client paid $95,000 gross, but contribution falls from a planned $22,000 to $12,500 once crew is costed properly. Multiply that pattern across 25 events a year and the business has given away roughly $200,000 of margin without ever seeing a “loss-making” month on a blended P&L. Per-event crew costing is not optional detail; it is the pricing curriculum.
The unit of management is the event, and the ledger tracks it as a job from first deposit to final reconciliation: contracted revenue, deposits and progress billings, committed and incurred costs by category, and contribution. Three reporting beats run the business.
Pre-event: the budget-versus-committed view, catching scope creep while the client conversation can still reprice it, a variations discipline borrowed directly from construction, because “can we just add” is where event margins go to die.
Post-event, within days: the final reconciliation, all supplier invoices chased in, crew costs landed, recoverables billed, margin trued against budget while memories are fresh. An events business that reconciles events quarterly is running on folklore; the one that closes each event inside a week compounds its pricing knowledge with every job. A project profitability calculator is useful only when job codes already capture the real costs.
Monthly: the portfolio view, delivered events’ margins against budget, the contracted pipeline with its deposit and commitment schedule, the unearned revenue balance against bank, and overhead coverage, how much monthly fixed cost the year’s contracted contribution has already paid for. Seasonality makes the annual view essential: a business earning 70 per cent of contribution across four months must bank those months’ surpluses against the quiet ones deliberately, which the deposit-liability discipline above makes visible and the blended cash balance forever hides.
Assume annual contribution of $720,000, with $500,000 earned from September to December and $220,000 across the other eight months. Monthly fixed overhead is $45,000 ($540,000 a year). Peak months must deliberately retain surplus so the quiet months do not raid next season’s deposits. If the operator treats peak bank balances as free cash and draws $80,000 for equipment and owner drawings in November, January to April become a client-funds problem dressed up as a cashflow crisis. The monthly pack that shows contracted contribution against remaining overhead months stops that story before it starts.
Run that machine, deposit schedules, principal-agent-clean invoicing, crew costed and compliant, events closed in days, and an event company becomes what it rarely is: a business whose bank balance means something. Building and running it is a defined weekly and per-event rhythm, exactly the standing engagement an embedded finance team carries for event and conference operators, typically for less than one season’s deposit drift costs in interest, lost margin and owner stress. For ongoing cost of bookkeeping context, pair the catch-up of historical jobs with a standing monthly pack so the next season does not rebuild the mess.
How should client deposits be recorded?
As unearned revenue, a liability per event, released to income on delivery. The cash is real but committed, and the per-event schedule of deposits against supplier commitments is what stops one event’s money funding another’s costs.
Do we charge GST on deposits?
Usually yes: most event deposits are part-payments of the contract price, attracting GST on normal attribution when invoiced or received. Only genuine security deposits, held against performance and refundable, defer GST until applied or forfeited, so classify what your contracts actually create and invoice accordingly.
What is the principal versus agent question?
Whether you buy and resell a service (principal: gross revenue, cost of sales, GST on the full charge) or arrange the client’s own purchase (agent: fee revenue only, pass-through outside your books). Contracts and conduct decide it per line, and the decision changes reported revenue, GST mechanics and supplier-failure exposure.
Can we mix principal and agent treatments?
Yes, and most event companies do: venue as agent, production as principal, management as fee. The requirements are that each line’s position is set in the engagement terms, invoiced in the matching form, and coded consistently, so the ledger reflects the model rather than habit.
Are event crew contractors or employees?
Hourly crew working personally are employees for superannuation purposes regardless of ABN, and payroll tax’s contractor provisions examine the same arrangements. Genuine labour hire or production company supply sits outside both. Decide and document per person before the event, and cost every crew hour to its event at the loaded rate.
Why reconcile each event within days?
Because margin truth decays: supplier invoices, crew hours and recoverables are collectable and explainable in the first week and folklore by the next quarter. Fast closes also compound pricing knowledge, each event’s actuals feeding the next quote.
What should the monthly pack show?
Delivered event margins against budget, the contracted pipeline with deposits and commitments scheduled, the unearned revenue balance against the bank balance, and overhead coverage from contracted contribution. That view, plus the seasonality plan, is the difference between managing the year and surviving it.
What is the single most dangerous habit in event company finances?
Treating the bank balance as available cash. Deposits belong to undelivered events, and the business that spends them on prior events’ costs is running a conveyor of obligations that only stays upright while bookings grow. The deposit-liability discipline exists to make that drift visible on day one.
How do I know if we have already spent client money?
Compare total unearned revenue liabilities plus committed supplier costs to cash on hand plus contracted receipts still due. If liabilities and commitments exceed available and contracted cash, client money has already been used for something else.
Should overrides and production mark-ups sit in the same margin line as management fees?
No. Report fee income and procurement margin separately so pricing and supplier decisions are visible. Blended margin hides which half of the model is carrying the business.
