Frequently Asked Questions About Voice Agents

Everything you need to know about working with flowio. Can't find your answer? Book a free consultation and we'll answer all your questions personally.

Pricing & Investment

At flowio, we believe in transparent, value-driven pricing. We offer a range of packages to suit your business needs, starting from £750. The investment consists of a one-off setup fee, covering voice persona design, knowledge base development, and API integrations. For aftercare, maintenance and support we offer a monthly subscription at £150 per month, and scaling upwards depending on the volume of calls and number of voice agents.
There are certainly other suppliers that offer voice agents for less than our starting price of £750. However, these are typically template-based solutions that lack the customisation and integration capabilities of our voice agents. They also lack human oversight, experienced prompt engineering, and ongoing data-driven analytical decisions that ensure your AI voice agent is always learning and improving. You wouldn't want your voice agent giving out it's system prompt to customers, would you? Or telling a joke in an emergency!
Most flowio clients see an immediate return on investment within the first 3 months. Results vary depending on the complexity of the automation and the volume of calls, however by automating high-volume repetitive queries, businesses typically reduce operational costs by 70% while eliminating call wait times. Our expertise shows that the real "investment" gain comes from "found revenue", AI agents can handle unlimited concurrent calls, ensuring no lead or customer inquiry ever goes unanswered, regardless of the time of day.
Yes. If your voice agent doesn't deliver the agreed functionality within 30 days of launch, we'll refund your investment in full. We're confident in our deployed voice solutions, because we've built real voice agents for over 20+ UK businesses to date.

Implementation & Timeline

Our streamlined implementation process typically takes 2 to 4 weeks. This timeline includes the "CX Discovery" phase, where we map your customer journeys, phone call flows and voice persona design, the "Agent Build" phase, where we program the agent with your specific business logic, and a rigorous testing phase. For complex enterprise integrations involving deep CRM synchronisation, and advanced telephony requirements (SIP trunking, IVR, etc.) timelines may extend slightly to ensure data integrity and security.
Yes. We integrate our builds with over 500+ tools including HubSpot, Outlook, Salesforce, CRM systems such as Go High Level, Stripe, Google Workspace, and more. If you're system has a secure API we can build a custom integration - including the ability to sync contact data with CRMs, check availability from multiple calendars, book appointments or meetings directly into calendars, and more. If a native connection does not exist - we engineer microservices to connect your systems, or provide alternative architected solutions.
No. We can develop your voice agent to run in parallel with your existing call centre operations - whether that's utilising IVR call routing, concurrency control, or a hybrid approach so there's zero downtime. Our team are experts in both voice agent development, and telephony integration, and can work with your existing call centre to ensure a smooth transition. Your team can continue working normally while we implement. We help your team get up to speed on how to use the data from the voice agents to assist their work.
We handle the heavy lifting. Our teamm of voice developers manage the technical architecture, automated workflows and integrate into your existing telephony infrastructure. Your involvement is primarily needed during the initial CX Discovery phase, providing us with your call flows, FAQs, brand tone guidelines, and access to relevant systems we'll need to integrate with. We aim to deliver a "turnkey" solution that empowers your team rather than adding to their workload.
Yes. WhatsApp can directly integrate with your conversational voice agent in a number of ways. We can integrate your agent as a chat-only onto WhatsApp - or build the ability for your customers to call in over a WhatsApp chat agent which can use both voice and text message to interact with. We also build voice agents that integrate with SMS for follow up messages or verification, email and many more pre and post-call workflow integrations.

Support & Maintenance

Our team are experts in voice agent prompt design, and utilise industry-leading guardrails, prompt engineering, and monitoring to ensure your voice agent stays on track. Many voice solutions out there lack the necessary safety features to prevent your agent from going off-track, or being misled by a customer's input. Every call is analysed post-call to provide optimisation improvements which go directly back into the prompt design, with version control and iterative testing.
Our automations are built with monitoring and alerts, so we often fix issues before you notice them. For urgent problems, our UK-based team responds within 1 hour during business hours via phone, email or WhatsApp. We also provide out-of-hours emergency support for business-critical automations.
Our voice agents are built to handle unknowns. If the AI doesn't know the answer, it can either transfer the call to a human, or provide a generic response. We also build in fallback processes by default to ensure your customers always get a resolution.
Yes. There are a number of situations where it's useful to transfer to another phone number or a human operator. We have previously built in scenarios for transfer into voice agents for our clients, such as if a user appears to be having a medical emergency for a dental clinic voice agent, or if a user reports the smell of gas when dealing with our boiler service voice agent for a trades company. To do this effectively we require integration into your telephony system, we utilise Twilio and build SIP trunks to seamlessly transfer calls to your existing phone system.
