Custom AI Agent Development

Autonomous AI agents.
Built in your stack.
Guarded by humans.

We build custom AI agents for service businesses that take real actions: triage inboxes, draft estimates, parse messy supplier PDFs, qualify leads, and sync disparate systems. Fixed price quoted before we start, bounded by strict confidence thresholds, delivered in 1 to 3 weeks. You own the code and the credentials outright.

Agents that execute decisions, not generic chat bubbles.

Most "AI solutions" sold to small businesses are rebranded ChatGPT widgets pasted into the corner of a website. They answer basic questions from a static FAQ and fail the moment a customer asks about a specific job status, an open estimate, or complex scheduling constraints.

A production AI agent is fundamentally different. It is an autonomous software component connected directly to your existing operational tools via APIs (CRMs, billing software, email, databases, phone systems). It receives an event, reasons through the context against your business rules, takes a specific structured action, and knows exactly when to escalate to your team.

The three rules of a reliable business agent

  • Narrow boundaries. An agent that tries to run your entire company will fail. An agent scoped to extract line items from supplier PDFs or draft personalized quote follow-ups based on job history succeeds consistently.
  • Confidence scoring & approval queues. If the agent's confidence score on an extraction or decision is 98%, it processes automatically. If confidence drops to 78%, it routes the drafted record to a human review queue with the ambiguous field highlighted.
  • Full data isolation & tool ownership. The agent runs on your accounts, authenticates with your API keys, and never leaks your customer records to public training sets.

Six production AI agents for service businesses

📥

Inbox Triage & Classification

Ingests inbound emails and SMS, classifies urgency, extracts job details and addresses, tags the contact in your CRM, and drafts contextual replies for one-click staff approval.

📝

Quote & Proposal Drafting

Reads project specifications, RFP documents, or technician field notes. Looks up your rate cards and historical estimates to build accurate, line-item drafts inside your CRM.

📄

Unstructured Document & PDF Parser

Extracts messy data from supplier invoices, bills of lading, subcontractor agreements, or receipts. Validates math, checks for duplicate line items, and syncs directly into QuickBooks.

🤖

Smart Front-Desk & Booking Agent

Converses naturally with leads via SMS, WhatsApp, or webchat. Checks live calendar availability, answers specific service questions, qualifies budget, and schedules confirmed bookings.

🎯

Lead Scoring & Routing Agent

Evaluates incoming inquiries against historical closed-won deals. Identifies high-value enterprise or commercial accounts and routes alerts directly to the right specialist with key talking points.

🔄

Cross-System Reconciliation Agent

Continuously compares operational records between disconnected software (e.g. dispatch software vs invoicing vs payroll). Flags mismatches and discrepancies before month-end close.

Engineered for zero hallucinations and total reliability.

We treat LLMs as reasoning engines within strict software guardrails, not unmonitored decision makers.

Deterministic Schemas

All LLM outputs are forced into strict JSON schemas with programmatic type checking. If a field fails format validation, the agent retries with error feedback or safely aborts.

Human-in-the-Loop Queues

High-consequence actions (sending external emails, updating financial ledgers, deleting records) stage drafts in an approval UI until authorized by a team member.

Zero Retainer Lock-In

All agent workflows, code, prompts, and server instances belong to you. If we part ways, your agents keep running without interruption on your own infrastructure.

Any software with an open API or webhook capability: HubSpot, Salesforce, Pipedrive, Jobber, ServiceTitan, QuickBooks, Stripe, Google Workspace, Microsoft 365, Slack, Twilio, Samsara, and proprietary PostgreSQL/MySQL databases. We also build custom API adapters when legacy systems lack native connectors.

No. We build directly with enterprise API endpoints (OpenAI, Anthropic, AWS Bedrock, Google Cloud Vertex) where commercial agreements explicitly prohibit using customer API inputs and outputs for model training.

All builds include automated error handling, retries with exponential backoff, and direct alerting to your team's Slack, Teams, or email. We include a 30-day fix-anything window post-launch, and offer optional ongoing monitoring plans starting at $149/mo.

No. Every deployment includes recorded video walkthroughs and thorough written documentation written in plain English. For routine parameter tweaks (such as updating prompt wording or notification recipients), non-technical staff can make updates easily.
