[Get My Fixed Quote](https://www.everstonecpa.com/book-online)[Ask a Free Question](https://www.everstonecpa.com/quick-question) **Quick answer:** Agency and consulting accounting differs from ordinary small business accounting because retainers are billed before the work is done, project revenue rarely matches invoice dates, pass-through media and production costs distort revenue if reported gross, and delivery teams built from contractors raise classification questions. With nothing physical to anchor them, these are decisions. An agency sells time and judgement: no inventory, few assets, a balance sheet of receivables and deferred revenue. That is why the accounting slips. With nothing physical to anchor it, revenue recognition and cost classification are judgement calls.

Both facts distort the two figures everyone reads first — revenue and profit — unless the books separate earning from being paid, and pass-through spend from fee income. ### Being paid is not the same as earning A retainer invoiced on the first for that month’s work is deferred revenue until the work is done; a project billed at signing is deferred until milestones are met. Conversely, a phase delivered in December and invoiced in January is December revenue. Recognizing revenue on invoice produces strong and weak years purely from billing rhythm, reversing whenever a large retainer starts or ends. ### Pass-through costs distort everything Media, print, production, licensing and subcontractors often pass through an agency’s account without being its revenue. Gross reporting inflates revenue and crushes margin; net understates activity. Principal or agent decides it; apply it consistently. Recharged costs usually carry sales tax, whether or not the supplier charged it. ### Your delivery team is a classification question Agencies scale through contractors. Fixed hours, agency systems, daily direction and no other clients look like employment, and a reassessment brings retroactive [source deductions](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/payroll/remitting-source-deductions.html) with penalties. A consultancy reliant on one client faces the [personal services business](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/t4012.html) analysis. ### Clients are often not in your province, or your country Place-of-supply rules set the rate by client location, so a BC agency charges Ontario and Alberta clients different rates. Services to non-residents are often [zero-rated](https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/rc4022.html), so firms with US clients usually get refunds. ### Unbilled work and bonus timing Unbilled year-end work in progress belongs in the period earned. Bonuses declared to cut corporate income must be paid within a set window to be deductible that year, so they are cash decisions too. ## The guides and pages for this vertical Grouped around the two things that distort an agency’s numbers: revenue and timing at one end, and the services that keep the books straight at the other. ### Revenue, timing and year end - [Cash versus accrual accounting](https://www.everstonecpa.com/blog/cash-vs-accrual-accounting-canada) — why a retainer business cannot read its performance off its bank balance. - [Prepaid expenses at year end](https://www.everstonecpa.com/blog/prepaid-expenses-year-end-canada) — software, subscriptions and insurance paid ahead, and how they are split. - [Accrued bonuses and the payment window](https://www.everstonecpa.com/blog/accrued-bonus-180-day-rule-canada) — the rule that decides whether a declared bonus is deductible this year or next. - [Bonus or dividend at year end](https://www.everstonecpa.com/blog/bonus-vs-dividend-year-end-canada) — the annual decision about how profit leaves the corporation. - [Writing off bad debts](https://www.everstonecpa.com/blog/writing-off-bad-debts-canada) — for the client that stopped paying halfway through a project. - [Choosing a fiscal year end](https://www.everstonecpa.com/blog/corporate-fiscal-year-end-canada-how-to-choose) — why a services firm may not want a December year end at all. ### Your team and how it is engaged - [How CRA classifies a worker](https://www.everstonecpa.com/blog/employee-vs-contractor-cra-worker-classification) — the factors weighed when a contractor looks like an employee. - [Employee or contractor, for the hiring business](https://www.everstonecpa.com/employee-vs-contractor-hiring-canada) — the commitments each model creates.

A retainer billed on the first for that month’s work is deferred revenue until the month is worked. Recognising it on invoice overstates the start of an engagement and understates the end. [Ask about your case →](https://www.everstonecpa.com/quick-question) **Should media buys and production costs be in my revenue?** It depends on whether the firm is principal or agent — carrying risk and controlling the service, or just arranging and recharging it. Gross reporting inflates revenue and collapses margin. Apply it consistently so years compare. **My contractors work full time for us. Is that a problem?** Yes, they can be. Set hours, your systems, daily direction and no other clients resemble employment, whatever the contract says. Reassessment brings retroactive source deductions, interest and penalties; review it early. **Do I charge GST to a client in the United States?** Services to non-residents are often zero-rated: no tax charged, input tax credits still recoverable. Conditions apply where the service relates to Canada, so check rather than rely on the address. **What rate do I charge a client in another province?** Rates generally follow the client’s location, so a BC agency may charge Ontario and Alberta clients differently for identical work. Set it up in invoicing early; fixing a year of invoices is harder. **Can I declare a bonus to reduce this year’s corporate tax?** Yes, if paid within a set window after year end, and it brings source deductions. It is a cash decision too; compare a dividend first. ## A CPA for professional-services firms Deferred retainers, cross-border clients, or a contractor roster that is starting to look like a payroll — describe how the firm delivers and you will get a straight answer.
