Tested and compiled by Vincent Wesley Couey and the Rinzara editorial team · 10 tools priced at agency seat counts · methodology & sources · all pricing read from vendor pages 2026-08-12.
Seats are the first constraint and they are rarely in the comparison
Every headline price in this category is a single-seat price. Agencies do not buy single seats, and the per-editor charge frequently changes which tool is cheapest. Everything below was read from the vendors' own pricing pages on 12 August 2026.
| Tool | Single seat | Extra seats | Three seats |
|---|---|---|---|
| Colossyan | $59/mo | $30/mo each | $119/mo |
| ElevenLabs Scale | $299/mo | 3 included | $299/mo |
| ElevenLabs Business | $990/mo | 10 included | $990/mo |
| Cartesia | $5 to $299 | Unlimited seats | Same price |
| Murf | $19 to $66/mo | Enterprise, 5+ | Quoted |
| Synthesia | $19/mo monthly | Enterprise | Quoted |
| HeyGen | $29 to $49/mo | Team plans | Quoted |
| The seat model matters more than the headline | |||
| Cheapest at 1 seat | Cartesia $5 | Voice | Unlimited seats |
| Cheapest at 3 seats | Cartesia $5 | Voice | Still $5 |
| Steepest seat curve | Colossyan | +$30 each | 2x at 3 seats |
A commercial licence and a client-work licence are different grants
This is the distinction that catches agencies, and it is easy to miss because the word commercial appears in both cases.
A personal commercial licence typically covers using output in your own business: your marketing, your channel, your product. Work delivered to a paying client is a different arrangement, because the asset is being sold on and the client will expect rights to it. Some vendors separate these explicitly. Murf distinguishes a Personal License on Creator at $19 from a Business License on its $66 tier. Loudly separates a Personal License on its $8 plan from a Pro License on its $24 plan, with the Pro tier naming digital advertising campaigns and client works.
The practical consequence: the tier that is correct for a freelancer producing their own content is frequently the wrong tier for the same person doing the same work for a client. The output is identical; the licence required is not.
Three questions to answer before any agency purchase:
- Does this tier permit work delivered to a third-party client?
- What rights does the client receive in the asset, and can they use it after we stop paying?
- If the client is later acquired or the campaign is resold, does the licence travel?
None of these appear in a features table, and all three will be asked by a client's legal team eventually. The answers live in the terms page, not the pricing page.
Indemnification is why enterprises pick the less capable model
Agencies working with large clients routinely choose Adobe Firefly over models that produce better images, and the reason is not aesthetic. It is that the buyer wants someone else to carry the risk if a generated asset turns out to infringe.
That is a rational purchase even when the output is measurably worse, because the cost of a single infringement claim exceeds years of subscription difference. If your client's procurement process asks about indemnification, the model comparison is effectively over before it starts, and pretending otherwise wastes everyone's time.
Where the risk sits also depends on the openness model. Black Forest Labs publishes an open weights track alongside its API, which means a pipeline can keep running independently of the vendor. That is valuable for continuity and it does not transfer legal risk to anyone. Self-hosting solves availability, not liability.
Compliance certifications are the adjacent question and they are checkable. Murf lists HIPAA, GDPR, ISO 27001 and SOC 2 Type II on its pricing page. Cartesia addresses SOC 2 and offers DPAs and BAAs at enterprise. ElevenLabs offers custom terms, DPAs, BAAs for HIPAA customers and custom SSO at enterprise. A named certification on a pricing page is verifiable; a claim of being enterprise ready is not.
The agency stack, stage by stage
Assembled for a small agency doing client campaign work rather than a solo creator producing their own content.
- Voice: Cartesia. The seat model is the reason. Cartesia states unlimited workspace seats and voice slots on every plan, so a three-person team pays the same as one person. Commercial licence starts at $5, and Scale at $299 adds priority support and high concurrency. ElevenLabs Scale at $299 includes 3 seats and Business at $990 includes 10, which is the alternative if you want the wider platform.
- Music: Soundraw Creator at $11.04 for background scoring with unlimited downloads, or Loudly Pro at $24 if you need its Pro License covering digital advertising campaigns and client works.
- Stills: Adobe Firefly when indemnification is required, Photoroom Max at $20.99 for product work at 3,000 exports a month, or Flux when you need a pipeline you control.
- Presenter video: Synthesia if the client's procurement has an approved vendor list, since it is most likely to already be on one. HeyGen Creator at $29 if you need 175+ languages and voice cloning at a self-serve price. Colossyan for interactive and training deliverables, remembering the $30 per extra editor.
A realistic three-seat agency stack lands around $60 to $90 a month for voice, music and stills, before presenter video. That is small enough that the seat and licence questions matter far more than the price, which is exactly the point of this page.
The buying sequence that avoids expensive mistakes
Run these in order. Reversing them is how agencies end up re-purchasing a tool six weeks after standardising on it.
- Count the seats and price the real team. A per-editor charge can double the cost between one and three people, and Colossyan's $30 each is stated openly on its pricing page.
- Read the client-work clause. Establish whether the tier covers assets delivered to a paying third party, and what rights the client receives.
- Ask about indemnification early. If the client requires it, the shortlist collapses immediately and you save the evaluation entirely.
- Check the certifications you will be asked for. SOC 2, ISO 27001, GDPR and where relevant HIPAA. Named on a pricing page is checkable.
- Set every pricing page to the same billing term. This category quotes annual prices as headlines almost universally, verified across six vendors on one day.
- Only then compare features. By this point the shortlist is usually two tools, and the feature comparison takes an afternoon rather than a fortnight.

Frequently asked questions
What do AI creative tools cost for a three-person agency?
It depends far more on the seat model than the headline price. Colossyan charges $30 per month for each additional editor, so its $59 plan is $119 for three people. Cartesia states unlimited workspace seats on every plan, so a three-person team pays the same $5 to $299 as one person. ElevenLabs includes 3 seats at Scale for $299 and 10 seats at Business for $990. A realistic three-seat stack for voice, music and stills lands around $60 to $90 per month.
Does a commercial licence cover work I deliver to clients?
Not always, and the distinction is easy to miss because both are called commercial. A personal commercial licence typically covers output used in your own business. Work sold on to a paying client is a separate grant on several platforms: Murf distinguishes a Personal License at $19 from a Business License at $66, and Loudly separates a Personal License at $8 from a Pro License at $24 that names digital advertising campaigns and client works. Read the terms page rather than the pricing page.
Why do agencies choose Adobe Firefly over better image models?
Indemnification. Large clients want a vendor carrying the risk if a generated asset turns out to infringe, and that consideration outweighs image quality because a single claim costs more than years of subscription difference. If a client's procurement asks about indemnification, the model comparison is effectively decided before it begins. Note that self-hosting an open-weights model such as Flux solves continuity and availability, not liability.
Which AI tools publish security certifications agencies can verify?
Murf lists HIPAA, GDPR, ISO 27001 and SOC 2 Type II on its pricing page. Cartesia addresses SOC 2 in its FAQ and offers DPAs and BAAs at enterprise tier. ElevenLabs offers custom terms and assurance around DPAs and SLAs, BAAs for HIPAA customers and custom SSO at enterprise. A specific named certification is checkable and a general claim of being enterprise ready is not, so ask for the former.
What order should an agency evaluate AI creative tools in?
Count the seats and price the real team first, since per-editor charges can double the cost. Then read the client-work clause to confirm the tier covers assets delivered to third parties. Then ask about indemnification, which often collapses the shortlist immediately. Then check the certifications procurement will request. Then set every pricing page to the same billing term, because this category quotes annual prices as headlines almost universally. Compare features last.
