End-to-end AI agent & automation solutions
We don't build chatbot demos. We build AI systems that handle real business operations — integrated into your existing tools, running 24/7, with no human babysitting required.
AI agent development services & core agent types
Each agent type is built for a specific job. Most clients combine two or more into a connected automation stack.
AI voice agents — inbound & outbound
VAPI, Call Routing
AI voice agents are the fastest-growing category of business automation. Built on VAPI and powered by OpenAI or Claude, they handle phone calls with natural, low-latency conversation — indistinguishable from a human assistant for most routine interactions. We build inbound agents for service businesses, clinics, law firms, estate agents and any operation that receives high call volumes. Outbound agents handle follow-up calls, appointment reminders and lead reactivation campaigns. Every agent is trained on your business knowledge, integrated with your calendar and booking system, and deployed with full call logging and escalation rules.
AI SDR & lead qualification agents
CRM, Automated Sprints
An AI SDR agent works your inbound lead list 24 hours a day — responding to new enquiries within seconds, asking the right qualification questions, handling objections and booking meetings directly into your sales team's calendar. Built on OpenAI or Claude and integrated with your CRM (HubSpot, GoHighLevel, Salesforce or others), these agents ensure no qualified lead ever goes cold because a human wasn't available. We also build outbound SDR agents for re-engagement campaigns — working dormant leads, past customers and marketing list contacts at scale.
AI customer support agents
Tier-1 Multi-Channel Support
Customer support is the highest-volume, most repetitive function in most service businesses — and the most logical candidate for AI automation. We build custom support agents trained on your documentation, product knowledge and historical support data. Deployed via web chat, WhatsApp, email or SMS, they handle tier-1 queries instantly and pass complex cases to your team with full conversation context already attached. Unlike generic chatbot tools, these agents are built to your exact workflows — including your escalation logic, your tone of voice and your specific product edge cases.
n8n workflow automation
Self-Hosted Pipelines
n8n is the most powerful self-hosted automation platform available — and our preferred tool for clients who want full control over their data and workflow logic. We build complex n8n workflows connecting your CRM, email, calendar, database, communication tools and AI layer into a single, coordinated operational pipeline. Whether you're running n8n on your own server or on n8n Cloud, we design workflows that are maintainable, documented and built to handle real-world edge cases — not just the happy path.
Zapier & Make.com automation
Rapid API Integrations
For businesses already using Zapier or Make.com, we build, extend and optimise workflows that go beyond basic two-step automations. Complex multi-branch logic, error handling, data transformation and AI-augmented steps — built to the limits of what these platforms can do. We also advise on when it makes sense to migrate from Zapier or Make.com to n8n for cost, performance or control reasons.
OpenAI & Claude API integrations
RAG & LLM Work
Most businesses don't need an off-the-shelf AI product — they need AI embedded into their specific workflow, trained on their specific data, producing outputs in their specific format. We build custom integrations using the OpenAI API and Anthropic Claude API — including prompt engineering, function calling, retrieval-augmented generation (RAG) with vector databases, fine-tuning pipelines and structured output systems that feed directly into your existing tools.
AI document processing
Data Extraction Pipelines
High-volume document handling — invoices, contracts, applications, compliance forms, medical records — is one of the clearest ROI opportunities for AI automation. We build end-to-end document processing pipelines that intake documents from email, upload portals or cloud storage; use AI to extract, classify and validate the relevant data; and push structured outputs into your CRM, database or ERP automatically. Handles PDFs, scanned images, Word documents and mixed-format batches.
Automation systems we've delivered
Real projects. Real outcomes. Every system below runs in a live business environment.

Why choose PSI Square as your AI automation development company
Four pillars of production-grade AI engineering.
We build for your workflow, not a template
Every AI agent and automation system we deliver is built specifically for your business — your tools, your data, your logic and your edge cases. We don't resell off-the-shelf chatbot products with a different logo on top.
Production deployment, not proof of concept
The gap between a demo and a live system is where most AI projects fail. We build for production from the first line — including error handling, fallback logic, rate limit management and the real-world conditions that demo builds ignore.
Deep integration capability
AI agents only deliver value when they're connected to the right systems. We have deep experience integrating with CRMs, ERPs, calendars, helpdesks, databases and communication platforms — so your AI layer and your business layer operate as one.
You own everything, always
Full source code, workflow files and documentation delivered with every project. No platform lock-in beyond the tools you choose. No ongoing licensing fees to us. If you want to take the work in-house or to another developer, you can.
How we work
A structured process that keeps your project on track from first call to live deployment.
Is this the right fit for you?
We work best with clients who have a clear operational problem and want a properly built solution.
This is a strong fit if you:
VERIFIED COMPATIBLE- Have a specific business process that consumes significant staff time
- Are receiving inbound enquiries or leads that aren't being handled fast enough
- Want AI integrated into tools you already use — not a separate product to manage
- Value properly built, documented, maintainable systems over quick hacks
- Want a development partner who will still be available after launch
Probably not the right fit if you:
POTENTIAL MISALIGNMENT- Want to "explore AI" without a defined use case or problem to solve
- Are looking for a fully autonomous agent that requires zero human oversight — for most businesses, some oversight is appropriate and we'll tell you honestly where
- Need something live in 24 hours with no specification process
- Are primarily comparing on price rather than capability and reliability
Not sure if automation is right for your situation? Book a free call — we'll give you an honest assessment, not a sales pitch.

"The n8n workflow they built completely transformed our onboarding process. We were doing 15 hours of manual data entry a week, and now it's zero. They handled all the API edge cases we didn't even know existed."

How projects are priced
Every AI agent and workflow automation project is scoped individually — because a single inbound voice agent and an enterprise multi-channel, CRM-integrated AI operations stack are completely different engagements. We deliver production-ready systems rather than experimental prototypes.
Single-function agents (such as an inbound voice receptionist or lead qualification SDR) typically start from $1,500 with turnaround in 7–14 business days. Complex multi-agent architectures and enterprise workflow integrations typically range from $3,500 to $8,000+ with 3–6 weeks delivery.
Book a free 30-minute consultation. We'll scope your architecture, recommend the optimal stack (OpenAI, Claude, VAPI, n8n), and send a fixed-scope milestone proposal within 24 hours.
