When to choose Synthflow

  • Scale and control: custom concurrency, SIP trunking, contact-centre integrations, APIs and webhooks, for teams with high call volumes.
  • Security and procurement: SOC 2 Type 2, ISO/IEC 27001 and GDPR listed in its Trust Center, with MSA and DPA support.
  • White label: agencies, BPOs and software platforms can resell voice agents under their own brand.

When to choose VocalReception

  • A public price you can check today: €79 excl. VAT a month for 400 minutes, and €0.25 per extra started minute.
  • No annual contract and no sales scoping call: monthly, with no commitment.

  • A monthly report lists the questions left unanswered, so the receptionist knows the answer the next month.

The two offers in one sentence

Synthflow is an enterprise platform for building AI voice agents, run by AgentFlow AI GmbH in Berlin and sold on an annual agreement with custom pricing (source 1, source 2). VocalReception is a done-for-you AI receptionist for small businesses: €79 excl. VAT a month for 400 minutes, configured and tested by our team (pricing).

Cost by call volume

The figures assume monthly billing, one business, inbound calls only, and no SMS, setup or VAT.

Minutes a monthVocalReceptionSynthflow
100€79Not public
400€79Not public
1,000€229Not public

Formula for VocalReception: €79 + €0.25 × (minutes - 400). Synthflow cannot be priced from public information: its pricing page says it has no free plan, no trial and no rate by the minute, and that each contract is scoped to your call volume, phone system, integrations, security needs and launch support (source 1).

If you ask Synthflow for a quote, ask for: the yearly minimum, the price per minute or per call inside the agreement, what launch support costs, what happens if you exceed the volume, and the notice period to end the contract. Then compare the monthly figure with ours in the pricing simulator.

Build it yourself, or have it done for you

Synthflow is a toolbox. Your team, or Synthflow’s forward-deployed engineers when the agreement includes launch support, designs the agent: call flows, routing, transfers, integrations with your CRM or contact-centre stack (source 1). Deployment takes “weeks”, depending on integrations and security review. That is the right shape for a company running many lines, many agents or a white-label service.

A small business with one phone line usually needs something else: a receptionist that answers, transfers and takes the right details, without a project. That is what we deliver. After a one-hour workshop, our team writes the script, sets up transfers, tests the calls and goes live in 7 days. The €199 setup fee is credited on your seventh invoice after six paid months. Our guide to AI receptionist software explains the difference between platforms and finished services.

Customer reviews

On Trustpilot, Synthflow AI shows 4.1 out of 5 from 215 reviews as of 5 November 2026 (source 4). Its pricing page also shows a G2 badge of 4.5 from more than 1,000 reviews, which we did not check on G2 itself. VocalReception does not publish customer reviews yet.

Our advice

If you are a mid-market or enterprise team with high volumes, in-house technical people and procurement requirements, Synthflow is a strong option. If you are a small business that wants calls answered next week at a known monthly price, start with VocalReception or try the demo.
