Full AI Call Center Agency Stack Built for Digital Flo™
Digital Flo™ is a US-based AI automation agency that delivers done-for-you AI call center systems to businesses — replacing $3,000–$7,000/month human appointment setters with AI voice and chat agents that respond in under 60 seconds, 24 hours a day. AKT engineered Digital Flo's complete backend infrastructure: Retell AI voice agents, Closebot chat and SMS agents, per-client GoHighLevel CRM builds, and n8n automation connecting every layer into one unified system — custom-built for each client's specific business.

The Challenge
Delivering bespoke AI call centers for every client — at agency speed and scale
Digital Flo's value proposition is powerful but operationally demanding: every client gets a fully custom AI call center — unique voice agent, unique chat and SMS flows, unique CRM pipeline, unique nurturing sequences — tailored to their specific industry, lead sources, and sales process. Delivering this consistently across a growing client base required a backend infrastructure that could be configured quickly, scaled reliably, and managed centrally.
Without a unified automation backbone, each new client meant manual setup across four separate platforms — creating bottlenecks, inconsistencies, and limits on how many clients Digital Flo could serve simultaneously. The company needed a technical partner who could build the infrastructure once and make it deployable at scale.
The AI call center market is also intensely time-sensitive: businesses replace human setters because leads are being lost to slow response. Digital Flo's AI systems needed to demonstrate sub-60-second response times across both voice and text — or clients would see no improvement over what they already had.
Without AKT
Voice agent setup
Manual per client — slow and inconsistent
Chat/SMS agent
No unified solution across platforms
CRM per client
Manual GHL build — hours per sub-account
Cross-tool data flow
Disconnected — manual data entry required
Client onboarding time
Days — bottlenecked on manual config
Lead response time
Delayed — tools not connected in real-time
Scalability
Hard limit on simultaneous client capacity
What AKT Built
Four integrated systems. One AI call center — unique for every client.
AKT built Digital Flo's entire technical backend — every layer from voice to SMS to CRM to automation — using Retell AI, Closebot, GoHighLevel, and n8n as a modular, scalable stack that can be configured per client in a fraction of the time manual setup would take.
01
Retell AI Voice Agents
AKT builds and deploys Retell AI voice agents for each of Digital Flo's clients — trained specifically on that client's business, products, sales objections, and qualification criteria. The voice agent handles inbound calls instantly (under 600ms response), runs outbound prospecting campaigns, qualifies every lead against the client's ideal customer profile, and books appointments directly into their calendar — without a human setter ever picking up the phone.

02
Closebot Chat & SMS Agents
AKT integrates Closebot — the #1 rated AI appointment setter for GoHighLevel — as the chat and SMS automation layer for every Digital Flo client. Running natively inside each GHL sub-account, Closebot handles all text-based lead conversations: answering questions, qualifying prospects, overcoming objections, and booking appointments — across SMS, web chat, Facebook Messenger, Instagram DMs, and more. Every conversation is logged and synced to the CRM pipeline automatically.

03
GoHighLevel CRM — Per-Client Build
Every Digital Flo client gets a fully configured GoHighLevel sub-account built by AKT from the ground up — not a template, not a cookie-cutter setup. AKT builds each CRM to match the client's specific sales process, lead sources, pipeline stages, and reporting needs. This includes custom pipelines, automated nurturing sequences, appointment calendars synced to voice and chat agents, trigger-based workflows, and performance dashboards that surface the metrics that actually matter to each client's business.
04
n8n Automation Backend
AKT built n8n automation as the central nervous system connecting every tool in Digital Flo's stack. When a lead comes in via web form, social ad, or inbound call, n8n routes them to the right agent (voice or chat), logs the interaction to GoHighLevel, triggers the appropriate nurturing sequence, updates the pipeline stage, and fires off any downstream actions — all in real time, with no manual touchpoints. n8n is also used to scale Digital Flo's client management: onboarding new clients, spinning up sub-accounts, and deploying agent configurations programmatically.
The Results
Custom AI call centers deployed at scale — instant response, automated booking, eliminated setter costs
Digital Flo now delivers fully operational, bespoke AI call center systems to each client — with voice agents, chat and SMS agents, CRM pipelines, and automation all connected and live. What previously took days of manual configuration can now be deployed faster, more consistently, and with a unified backend that Digital Flo controls centrally through n8n.
Every new lead that enters a Digital Flo client's pipeline gets an AI response within 60 seconds — whether via phone, SMS, web chat, or DM. The AI qualifies the lead, handles objections, and books the appointment directly into the calendar without a human setter involved. Booking rates, show rates, and conversion data feed back into GoHighLevel automatically.
The measurable client outcomes speak directly to the infrastructure AKT built: a 467% increase in qualified calls booked, cost per acquisition down 78%, average monthly revenue gains of $40,000+, and the complete elimination of $3,000–$7,000/month in human setter payroll — replaced by an AI system that works every hour of every day.

FAQ
Questions about AI call center agency infrastructure
What is Retell AI and how is it used in AI call center agencies?
▾
Retell AI is a production-ready voice AI platform with under 600ms response latency, 31+ language support, and native telephony integration. AKT used Retell AI to build Digital Flo's voice agent layer — handling inbound calls, running outbound campaigns, qualifying leads, and booking appointments automatically for each client without human involvement.
What is Closebot and how does it work with GoHighLevel?
▾
Closebot is the #1 rated AI appointment setter built natively for GoHighLevel agencies. It handles chat and SMS conversations — qualifying leads, handling objections, and booking appointments — directly inside GHL sub-accounts. AKT integrated Closebot as Digital Flo's text-based agent layer, synchronized with GoHighLevel pipelines via n8n.
How does AKT build a custom AI call center for each Digital Flo client?
▾
AKT configures each system from scratch based on the client's industry, lead sources, and business needs: a Retell AI voice agent trained on their products and objections, a Closebot SMS/chat agent in their GHL sub-account, a fully built CRM pipeline, and n8n workflows connecting every touchpoint. No two client builds are identical.
How much faster is AI lead response versus human appointment setters?
▾
AKT's systems built for Digital Flo respond to new leads within 60 seconds, 24/7. Research shows leads contacted within 5 minutes convert 100x more than those reached after 30 minutes. Human setters working business hours can't compete with an AI that responds instantly at any hour — and does it without payroll.
Can n8n connect GoHighLevel, Retell AI, and Closebot in one workflow?
▾
Yes. AKT built n8n as Digital Flo's entire automation backbone — routing leads from any source to the correct agent, syncing conversation data across all platforms, triggering pipeline updates, firing nurturing sequences, and provisioning new client sub-accounts automatically. The entire stack runs as one connected system.
What client results has Digital Flo achieved with AKT's AI call center system?
▾
Digital Flo clients powered by AKT's infrastructure have reported: 467% more qualified calls booked (3 → 17/week), cost per acquisition dropping from $450 to $97 (-78%), average monthly revenue gains of $40,000+, and elimination of $3,000–$7,000/month in human setter payroll — with 24/7 coverage that no human team can match.
