Every small firm eventually runs the same calculation, and usually runs it a year or two later than it should have. The question is simple to ask and awkward to answer: how much of the revenue actually goes to the place the firm works from? Not the rent alone — the whole apparatus of being somewhere.
The reason the calculation gets postponed is that the rent line looks small and knowable, while everything attached to it is neither. So it helps to lay the three common models side by side — a conventional lease, a coworking membership, and a virtual office — and look at the fully loaded picture rather than the headline number.
The rent line is the smallest number
A lease is quoted as a rate per square foot, and that rate is where most people stop reading. But the rate is the beginning of the cost, not the end of it. Depending on how the lease is structured, the tenant may also carry operating costs, utilities, insurance, maintenance, and property taxes — and beyond the recurring charges sit the one-time ones that rarely make it into the first estimate: fit-out, furniture, cabling, signage, and the deposit that disappears from working capital for the length of the term.
None of this is hidden or improper. It is simply the difference between the price of the space and the cost of occupying it — a gap that, for a small firm, can be the difference between a comfortable year and a tight one.
The traditional lease, fully loaded
A conventional lease makes sense when a firm has stable headcount, needs dedicated space it controls, and can commit for several years without flinching. Its virtue is control; its cost is commitment. The multi-year term is an asset when the business is predictable and a liability when it is not, because the obligation continues whether the firm grows into the space, shrinks away from it, or changes shape entirely.
For an established practice with a known trajectory, that trade is often worth making. For a firm that is still finding its size, signing a long lease early is one of the most common and most expensive mistakes in professional services — capital committed to square footage before the revenue exists to justify it.
Coworking: flexible until it isn't
Coworking answers the commitment problem by pricing access per seat per month. There is no fit-out, no furniture, no multi-year obligation — the firm pays for what it uses and can leave when it needs to. For one or two people, this is genuinely efficient, and the flexibility is real.
The arithmetic changes with headcount. Per-seat pricing is linear: what is reasonable for two people becomes conspicuous for six, and by the time a team is meeting regularly the monthly membership can rival the fully loaded cost of dedicated space — without the tenant ever controlling the premises. Coworking is excellent at the small end and quietly expensive as the firm grows.
The virtual office: presence without the footprint
A virtual office separates the thing a small firm actually needs early — a credible professional presence — from the thing it does not yet need — a permanent physical footprint. It provides a real business address in the right location, professional mail handling, a local phone presence, and meeting rooms that can be booked when a client or a delegation needs to be received in person.
For a government-adjacent firm, the location of that address is not incidental. An address inside the Promenade du Portage corridor reads to a federal client as part of the working landscape rather than a suburb of it. The firm gets the signal of establishment and the ability to meet in professional space, at a fraction of the cost of either a lease or a growing coworking membership — and it preserves capital for the people and business development that generate revenue.
The honest rule of thumb: match your overhead to the stage of your business. Stay light while you are building relationships and proving the model; take on physical space when the mandates justify it. The most expensive office is the one you signed for before you needed it — and the cheapest presence is the one that still looks entirely credible to the client across the river.
Matching overhead to stage
There is no single right answer, only a right answer for a moment in a firm's life. A solo advisor testing a Canadian federal practice, a two-person firm winning its first mandates, and a ten-person team with a stable book of work each occupy a different point on the curve — and the sensible model shifts as they move along it.
What ties the three together is the discipline of counting the whole cost, not the rent line, and of buying only the presence the business currently requires. The specific numbers depend on structure, term, and circumstance, and are worth confirming with your own accountant or advisor. But the principle is durable: a small firm's space should serve the work, not the other way around.
