Synthflow Starts at $29/mo. Your Real Bill Won't.
Synthflow's advertised pricing looks affordable but requires BYOK — Bring Your Own Keys — meaning you separately pay for ElevenLabs (voice), OpenAI (LLM), and Deepgram (speech-to-text) on top of the plan fee. Real-world users on Synthflow's Pro plan ($450/mo for 2,000 minutes) report actual monthly bills of $590–$770 once BYOK provider costs are added. That's 30–70% more than the advertised price.
DialsDone pricing is fixed and all-inclusive. Starter at $499/month includes 1,000 calling minutes, human-grade voice, AI objection handling, call transcripts, meeting notifications, and a dedicated US phone number. No API keys to manage. No surprise bills. No three separate vendor accounts to set up before you make your first call.

Common questions
What is the best Synthflow alternative?
It depends on whether bring-your-own-key pricing suits you. Synthflow is a capable voice-agent builder, but you supply and pay for the underlying model and telephony accounts separately, so the headline plan price is not the whole bill. If you would rather have one predictable invoice and no provider accounts to manage, a fully-included product like DialsDone is the trade you are looking for.
How does Synthflow's pricing compare to DialsDone?
They are not directly comparable, which is the point worth understanding. Synthflow plans sit alongside the model and telephony costs you bring yourself. DialsDone sells fixed monthly capacity with everything included: Launch is $89 for 200 minutes, Starter $499 for 1,000, and the Scale tiers run $1,399 for 3,000 minutes up to $4,050 for 10,000. Add up your expected all-in cost on both rather than comparing plan prices.
Do I need my own OpenAI or telephony account with DialsDone?
No. There are no API keys to supply and no separate provider accounts to open. Voice, telephony and a dedicated US number are included in the plan price. That is the main practical difference from a bring-your-own-key builder, and it cuts both ways — you also cannot swap in a different model of your choosing.
Is Synthflow better for building custom voice agents?
For genuinely custom agents, yes. Synthflow gives you more control over the agent design and lets you choose your own model, which matters if you are building something specific or embedding voice into your own product. DialsDone is built for one job — B2B outbound calling — and trades that flexibility away for working immediately.
Can I try DialsDone before committing?
Yes. Pricing is public and self-serve, and the Launch plan at $89 per month for 200 minutes exists so you can prove it on your own list before scaling. There is no annual contract and no sales process to get through first.
Who is responsible for TCPA compliance?
You are. On any plan where you provide the list, you are the caller of record and the data controller: scrubbing against the National Do Not Call Registry and applicable state registries, obtaining consent where it is required, and keeping consent records are your responsibility. DialsDone provides guardrails — calling-hour controls, opt-out handling and call recording — but does not scrub lists on your behalf unless you ask for it as a separate service.
