Hire Hyvä developer vs hire Hyvä agency: Which is better?
For a £20k–£60k Hyvä project, you have two practical engagement options: hire a freelance Hyvä developer (or a small team of them), or hire a Hyvä-specialist agency. Each has real trade-offs that affect your delivery risk, your cost, and your post-launch maintenance story.
This post is the honest framework — when each wins, when each loses, and how to pick.
The headline trade-offs
| Dimension | Freelance Hyvä dev | Hyvä agency |
|---|---|---|
| Hourly rate | £400–£700/day | £600–£1,200/day equivalent (fixed-price normalised) |
| Total project cost | Often 30–50% cheaper than agency | Premium for delivery accountability |
| Delivery risk | You carry it | Agency carries it (with fixed-price scope) |
| PM overhead | You handle it | Agency handles it |
| Single point of failure | High (one dev = one bottleneck) | Lower (team coverage) |
| Code review + QA | Often minimal | Built into agency process |
| Post-launch maintenance | Depends on dev's availability | Agency stays on retainer |
| Scope creep handling | Friction (re-quoting per change) | Process for it |
| Documentation + handover | Often light | Usually formal |
The fundamental trade: freelance is cheaper if it works; agency is more expensive but less risky. The right choice depends on how risk-tolerant your project can be.
When freelance Hyvä developers win
In rough order of "freelance is clearly the right call":
1. Small, well-defined tasks
A single Hyvä compatibility module. A specific PDP component. A Lighthouse perf-tuning audit. Anything that's 1–3 weeks of work with a clear deliverable.
For these, freelance is faster + cheaper. Hiring an agency for a £4k piece of work is overhead-heavy.
2. You have in-house technical leadership
If you have a senior in-house dev who can review the freelancer's code, write the spec, and handle escalation if the freelancer goes off-track — freelance works well.
Without in-house technical leadership, the freelance model is riskier because there's no one to catch quality issues before they ship.
3. Continuous small work
If you're shipping small Hyvä changes monthly (theme tweaks, new compatibility modules for newly-added extensions, ongoing perf maintenance), a part-time freelance Hyvä dev on retainer is more cost-effective than per-engagement agency fees.
4. Pre-revenue or budget-constrained
If you're a smaller merchant where the agency premium doesn't pencil out, a good freelancer at £500/day can ship a £15–25k Hyvä migration in 6–8 weeks. The risk is higher but the cost may be the only way the project happens at all.
5. You've worked with the freelancer before
The risk in freelance is unknown delivery. If you've worked with a Hyvä freelancer before and trust them, hiring them again is a clear win on cost.
When Hyvä agencies win
In rough order of "agency is clearly the right call":
1. Full Hyvä migration (£15k+)
A full Hyvä migration involves theme work, extension compatibility, performance tuning, QA, UAT, cutover. That's at least 4 disciplines + project management. A single freelancer is the bottleneck on all of them; an agency parallelises.
For migrations specifically, agency delivery is typically 30–40% faster than equivalent freelance work because of parallelisation.
2. Hyvä Commerce / Adobe Commerce B2B (£35k+)
Hyvä Commerce builds add Hyvä Checkout, often Hyvä Admin, often Adobe Commerce B2B features. The surface area is wider; the failure modes are more numerous; the QA cycle is more complex. Agency is the right answer here pretty much always.
3. Fixed deadline / sale-event timing
If you have a hard deadline (product launch, sale event, marketing campaign), an agency's process-driven approach is more likely to hit it. A freelancer who gets sick or distracted blows your timeline; an agency has team coverage.
4. You don't have in-house technical leadership
If you can't review the dev's code, can't write a precise spec, can't handle escalation — you need the agency's PM layer to translate between you and the engineering team. This is the most common reason mid-size merchants choose agencies.
5. You want delivery risk transferred
The whole point of fixed-price agency engagements is that if the project runs over, the agency eats the cost. You pay a premium for that risk transfer. For mission-critical projects, that premium is worth it.
6. You need post-launch support
Agencies typically offer ongoing retainer support after launch — bug fixes, small enhancements, perf maintenance. A freelancer who delivered your migration may or may not still be available 6 months later.
The hidden costs of freelance
Things that bite freelance engagements that don't show up in the day-rate calculation:
1. Your PM time
If you don't have a PM, you're the PM. Every meeting, every spec clarification, every status check — that's your time. For a 10-week project, expect 2–5 hours per week of your time. At your hourly rate, this adds £5–20k to the project's effective cost.
2. Scope creep friction
When scope changes (and it always does), freelancers re-quote the change. Sometimes they re-quote favourably; sometimes they don't. Either way, the renegotiation overhead is on you.
3. Quality assurance gap
Most freelancers don't have a separate QA function. They test their own code. Bugs in production after launch are common. If you don't have in-house QA, you'll be debugging post-launch issues yourself.
4. Documentation gap
Freelancers often deliver code without documentation. Six months later, when you need to extend the work, the next developer has to reverse-engineer it. Agencies usually deliver formal handover docs as part of the engagement.
5. Single point of failure
If the freelancer gets sick, takes another job, or has a family emergency, your project stops. There's no team backup. For multi-month engagements this is a real risk.
These hidden costs don't make freelance wrong — they just need to be accounted for in the comparison.
The hidden costs of agencies
Things that bite agency engagements:
1. Pricing premium
Agencies cost 30–50% more than equivalent freelance work for the same scope. The premium covers PM, QA, team coverage, retainer support, and accountability — but it's a real number.
2. Slower decision-making
Decisions flow through PM → engineering → back to PM → to client. Faster than enterprise but slower than direct-to-engineer freelance work.
3. Less direct relationship
You probably won't talk to the engineer writing your code daily. Most communication goes through the PM. For some clients this is good (less interruption); for others it's frustrating (less direct understanding).
4. Off-the-shelf process
Agencies have established processes that may not fit your workflow exactly. You either adapt to their process or pay extra for customisation.
These are real costs. For most projects they're worth it; for some they aren't.
The hybrid model — freelance executing under agency oversight
A pattern that sometimes works: hire an agency for scoping + project management + QA oversight, and have them sub-contract or co-engage with a freelance Hyvä developer for the actual implementation.
This works when:
- You trust the agency's process but want the lower freelance cost on engineering
- The freelancer is known + trusted (often a former agency employee)
- The agency is willing to manage someone they didn't hire
This works less well when:
- The agency can't QA work they didn't write
- Communication overhead doubles (you + agency + freelancer)
- Accountability gets muddy when things go wrong
Most agencies prefer all-in-house engagements for accountability reasons. Some are willing to do the hybrid for the right project.
The decision framework
A practical decision tree:
- Is the project under £8k of work? → Freelance (agency overhead is too high)
- Is it a single discrete task (one compat module, one component)? → Freelance
- Do you have in-house technical leadership? → Freelance is viable
- Is it a full migration / Hyvä Commerce / B2B build? → Agency
- Do you have a hard deadline? → Agency
- Are you risk-tolerant (small store, low downside)? → Freelance can work
- Is the project mission-critical (revenue impact, customer impact)? → Agency
- Do you want post-launch retainer support? → Agency
Two or more "agency" answers in your project profile = agency is almost certainly the right answer.
How to find good freelance Hyvä developers
If you've decided freelance is right:
- Hyvä community Slack. Specialists hang out here. Some are open to freelance work between agency engagements.
- Toptal, Codementor, similar quality-vetted freelance platforms. Vet for Hyvä-specific experience using the framework in How to find a good Hyvä developer.
- LinkedIn search "Hyvä developer freelance". Lower quality signal but useful for shortlist.
- Ask Hyvä agencies directly. Some agencies have freelance Hyvä devs they can recommend or refer to for projects too small for the agency itself.
Vet using the same three questions:
- How many Hyvä builds end-to-end in the last 18 months?
- Show me a Hyvä module you've written from scratch
- What's your typical mobile Lighthouse on your Hyvä work?
If you don't get specific answers, keep looking.
How to find good Hyvä agencies
If you've decided agency is right, see Top Hyvä agencies in the UK in 2026 for the shortlist + vetting framework.
Key criteria:
- Hyvä volume (30+ builds in 18 months minimum)
- Fixed-price model (not hourly)
- Public Hyvä community presence
- References available
- Timezone alignment
A real example
Two recent quotes for a similar £25k Hyvä migration:
Freelance quote:
- £400/day × 35 days = £14,000
- Plus 8 hours/week of client PM time × 8 weeks = ~£8k of opportunity cost
- Plus QA + post-launch fixes uncovered = ~£3k
- Plus scope-creep renegotiations = ~£2k
- Effective total: £27,000, delivered in 10 weeks with quality risk
Agency quote:
- £25,000 fixed-price
- Includes PM, QA, retainer support, formal handover
- Effective total: £25,000, delivered in 8 weeks with delivery risk on agency
The "freelance is cheaper" calculation rarely accounts for hidden costs. Once you add them, freelance and agency are often within 10–15% of each other on total cost — at which point the risk-transfer argument tilts the decision toward agency for most projects.
Bottom line
- Small, well-defined tasks → freelance (£500–£3k per task)
- Continuous small ongoing work → freelance retainer
- Full migration / Hyvä Commerce / B2B → agency
- Hard deadline / mission-critical → agency
- No in-house tech leadership → agency
If you're on the fence, the "what happens if the dev gets sick" question usually resolves it. If your project can absorb a 2-week pause without consequence, freelance is viable. If it can't, agency.
