Flat-fee or per-seat? It's a question about your hiring volatility.
There's no morally correct SaaS pricing model. Per-seat is more common; flat-fee is becoming common in tools that hit a specific size range. This guide is the cost analysis — when each model wins, what the trade-offs are, and how to decide.

Per-seat: the dominant model and why
Per-seat pricing won the SaaS pricing wars in the 2010s for a specific reason: it scales naturally with customer value. A 100-person team gets more value than a 10-person team, so a 100-person team pays more. The math feels fair, and it's easy to forecast revenue for the vendor.
Per-seat also fits well with deep, narrowly-used tools. If your CRM is only used by 5 sales reps at a 50-person company, you pay for the 5. That's the right unit.
Where per-seat breaks down
Per-seat punishes teams whose headcount fluctuates. Bringing on a contractor for a 6-week project adds a seat — and many tools bill for the full month even if the contractor leaves on day 14. Layoffs reduce the bill on next renewal but felt costs hit immediately.
Per-seat also breaks down when the tool is broadly but shallowly used. Five people on the team need timer access once a month each; per-seat says you pay full freight for all five.
Finally, per-seat starts to feel exploitative at the boundary where small studios become real agencies. Going from 4 to 8 members doubles your tool bill at every per-seat vendor in the stack, often in the same quarter. The pricing model itself becomes a hiring tax.
Flat-fee: when it makes sense
Flat-fee per workspace (or per tier with a cap) inverts the dynamic. The bill is the bill regardless of headcount within the cap. Hiring is free; firing doesn't change the bill either. The math is dramatic at 10+ members — typical per-seat tools run $120-$150/mo for 10 seats; Hoursmith's Studio is $15/mo annual.
Flat-fee works because it bets on the right thing — usage stability, not headcount. A 10-person team generates roughly 10x the time entries and invoices of a 1-person team, so the tool incurs ~10x the database / queue / email load. But the per-customer cost of building and shipping the tool doesn't scale with headcount; it scales with feature requests and support load, which doesn't directly track to seat count.
Where flat-fee breaks down
Flat-fee is wrong for solo users. If you'll only ever be one seat, a per-seat tool's solo price will beat a flat plan. Most flat-fee tools (Hoursmith included) ship a generous Free tier explicitly to handle this case — but the moment you upgrade for a paid feature, you're paying for capacity you don't use yet.
Flat-fee can also feel uneven if your usage is genuinely tiny. A 2-person studio shipping 1 invoice a month might do better on a per-seat solo plan than on a flat $15 Studio plan, unless they need a feature only the Studio tier unlocks.
The honest decision framework
Three questions to ask: First, what's your team headcount likely to be in 12 months? If it's stable, per-seat math will be roughly the same as today's, and per-seat may be cheaper. If it's growing or fluctuating, flat-fee removes the variable.
Second, do you actually need the paid features? If you're a solo on a Free tier and never need online payments / BYO email / reports, the flat-fee Studio plan is overpaying for capacity. Stay free.
Third, what does the math actually look like at your real team size? Don't compare on a single-seat price; compare on the seat count you actually have. A per-seat tool at $12/user/mo costs $144/mo for 12 seats; Hoursmith Agency is $31/mo annual for up to 25 seats. The right math depends on your exact size.
How Hoursmith does it
How Hoursmith picks its model
Hoursmith is flat-fee on every plan. Three plans (Free up to 3, Studio up to 10, Agency up to 25), one workspace price each. The 3/10/25 bands map to the realistic hiring shapes of solo freelancers, small studios, and growing agencies — most teams stay in one band for 12-24 months at a time.
We chose flat-fee for a specific reason: the differentiation story is honesty, and per-seat pricing for a billing tool creates a perverse incentive (the tool that helps you bill clients more is also taxing you on hiring). Flat-fee aligns the pricing model with the product positioning.
Teams over 25 are usually a Custom plan with negotiated pricing — email us. We haven't published an Enterprise tier because we want to talk to those teams first; the right shape is rarely the obvious one.
