Key takeaways
- Three cost tiers exist: marketplaces, managed offshore, and US-based agencies — and the rate gap is smaller than it looks.
- Add 20–40% of a manager's time to any unmanaged hire — that's the real cost gap.
- Turnover is the biggest hidden expense: re-hiring and re-training wipes out a year of rate savings.
- Compare fully-loaded cost per useful output hour, not the rate card.
The three cost tiers
Freelance marketplaces are cheapest per hour, and you get access and nothing else — no vetting guarantee, no payroll handling, no replacement coverage. Managed offshore staffing costs more per hour and bundles vetting, payroll, compliance, training and replacement. US-based agencies cost the most, largely reflecting US labor cost rather than better outcomes.
The costs that don't appear on the invoice
- Ramp time: 20–60 hours of your team's time before a hire is productive
- Rework: mistakes caught late cost far more than the hour that produced them
- Management: unmanaged hires typically consume 20–40% of a supervisor's week
- Turnover: replacing a churned VA costs the equivalent of one to two months of billing
- Compliance: misclassification exposure on direct offshore contracts
A worked example
Take a 40-hour support role. Option A is a cheap marketplace contractor plus roughly 8 hours a week of your ops manager's time. Once you price that supervision at its loaded cost, the contractor's invoice is barely half the real bill — and replacement risk stays on you.
Option B is a managed placement at a flat monthly rate with under an hour a week of oversight — vetting, payroll, coaching and a replacement guarantee included. The rate card says Option A is far cheaper. The ledger disagrees.
When the cheapest option is genuinely right
If the work is a one-off project, fully scripted, and you have a manager with real capacity to supervise, a marketplace contractor is the correct call. Managed staffing earns its premium on recurring roles that touch customers, money or systems of record.
Frequently asked questions
- Why do virtual assistant rates vary so much?
- The spread between marketplaces, managed offshore providers and US-based agencies reflects vetting rigor, management overhead and who absorbs replacement risk — not just labor markets.
- Is a monthly retainer cheaper than hourly?
- Usually yes for consistent workloads, because a predictable schedule is cheaper to staff than ad-hoc hours.
- Are there hidden fees when hiring a VA?
- Watch for placement fees charged as a percentage of salary, mandatory software fees, minimum-hour blocks, and overage rates. We charge no percentage placement fee and put the full engagement terms in writing before you commit.
