Agents that do the work

AI Agent Development

A workflow tool executes the path you drew. An AI agent chooses the path within boundaries you set — which is why agents handle messy, variable work that rules-based automation has never been able to touch.

The problem

Traditional automation versus AI agents

The difference is not intelligence. It is who decides the sequence.

Rules-based automation is deterministic: the same input always produces the same path, which is exactly what you want for payroll runs and payment settlements. It breaks when the input varies — an email that phrases the request differently, an invoice in an unfamiliar layout, a support ticket describing two problems at once. Every variation needs a new branch, and eventually the flowchart becomes unmaintainable.

An agent is given a goal and a set of tools, and works out the sequence per case. That flexibility is the value and the risk, which is why we constrain agents with typed tool schemas, scoped credentials, step limits, spend caps and mandatory human approval on anything irreversible.

The honest guidance: use rules where the process is stable and must be deterministic. Use agents where the input is messy and a human currently exercises judgement.

  • Rules: fixed path, predictable, brittle to variation
  • Agents: chosen path, adaptive, needs guardrails
  • Rules: every exception is a new branch to maintain
  • Agents: exceptions handled by reasoning, escalated when uncertain
  • Rules: audit trail is the flowchart
  • Agents: audit trail is a per-decision trace log
  • Best systems use both — deterministic rails, agentic judgement
Use cases

Agents we are asked to build

Sales agents

Qualify, enrich, research and open conversations at a volume no SDR team can match.

Support agents

Resolve tier-1 tickets end to end with real system lookups, not scripted answers.

Recruiting agents

Screen applications against role criteria, schedule interviews, keep candidates warm.

Research agents

Compile structured briefs from web, internal documents and databases on a schedule.

Workflow agents

Own a multi-system process — approvals, reconciliations, exception handling.

Lead generation agents

Build and verify target lists, then run first-touch sequences with a human gate.

Architecture

Agent architecture

Seven components. Weakness in any one is where agent projects fail in production.

01 Goal & instruction layerSystem instructions, role boundaries, refusal rules and success criteria — versioned, server-side, never user-editable.
02 LLM reasoningThe model decides the next action. Selected per task on accuracy, latency and cost, and abstracted so it can be swapped.
03 PlanningDecomposition into steps, with re-planning when a tool returns something unexpected and a hard step limit to prevent loops.
04 Tool callingTyped schemas over your APIs. Each tool has scoped credentials, input validation, timeout and retry policy.
05 MemoryWorking memory within a task, persistent memory across sessions — with retention policy and a way for users to see and clear it.
06 Retrieval (RAG)Grounding in your documents and records so the agent reasons over facts rather than recall.
07 Human-in-the-loopApproval gates on irreversible actions, confidence-based escalation, and a queue with full context attached.
08 MonitoringTraces, tool success rates, escalation rates, cost per task and quality evaluation on a sampled basis.
  • Least-privilege credentials per tool
  • Step and spend caps enforced in the runtime
  • Idempotency keys on every write action
  • Prompt-injection testing before go-live
  • Deterministic fallback when the agent cannot complete
  • Full replay of any past task from the trace store
Integrations

What agents connect to

An agent without tools is a chatbot. Integration work is usually the larger half of the project.

Every connector is a typed tool with its own credential scope, rate limit and audit line. Read tools and write tools are separated so an agent can be given lookup access without the ability to change anything.

  • CRM: Salesforce, HubSpot, Zoho, Pipedrive, Dynamics 365
  • ERP and finance systems, including custom and legacy
  • Databases: PostgreSQL, SQL Server, MySQL, MongoDB
  • Email: Gmail, Microsoft 365, transactional providers
  • WhatsApp Business API and SMS gateways
  • Calendars, ticketing and helpdesk platforms
  • Internal REST, GraphQL and SOAP services
  • Document stores: SharePoint, Google Drive, S3
How we deliver

Ten stages from first call to a system your team trusts

Every AI engagement runs this sequence. Small projects compress stages; regulated projects expand them. Nothing gets skipped silently.

Discovery

A working session with your operations and engineering leads to map the process, the systems it touches, and where the cost actually sits.

AI Opportunity Assessment

We score candidate use cases on data readiness, volume, error tolerance and payback, then rank them. Some come back "do not use AI for this" — you get that answer too.

Solution Architecture

Model selection, retrieval design, tool boundaries, data flow, failure modes and hosting topology, documented before code.

Proof of Concept

A narrow build against your real data to prove accuracy on the cases that matter, typically 2–4 weeks. Go / no-go decision at the end.

MVP

One workflow, end to end, in the hands of real users. Evaluation sets and quality thresholds are defined here, not retrofitted.

Production Development

Hardening: error handling, retries, fallbacks, cost controls, rate limits, observability, and a human escalation path for every automated decision.

Integration

Wiring into your CRM, ERP, HRMS, data warehouse, ticketing and messaging channels through APIs, webhooks and event queues.

Security Testing

Prompt-injection testing, access-control verification, PII handling review, dependency scanning and penetration testing before go-live.

Deployment

Staged rollout on your cloud or ours, with CI/CD, versioned prompts and models, and rollback in place from day one.

Monitoring & Optimization

Quality dashboards, drift detection, cost-per-transaction tracking and a retraining or re-prompting cadence agreed in writing.

Security & Governance

Security-conscious architecture, from the first design review

Enterprise AI fails on governance more often than on models. Every system we build is designed to support enterprise security requirements and to give your risk team answers rather than assurances.

Data privacy & residency

Your data stays in the region and tenancy you nominate. We architect for no-training-on-your-data configurations and document exactly which vendor endpoints see which fields.

Role-based access control

Retrieval and tool permissions inherit your existing roles. A user cannot surface a document through the AI that they could not open directly.

Authentication & authorization

SSO via OIDC/SAML, short-lived tokens for agent tool calls, and per-tool scopes so an agent holds the narrowest possible privilege.

Encryption

TLS in transit, AES-256 at rest, managed keys via your cloud KMS, and encrypted vector stores for embedded content.

API security

Gateway-level authentication, signed webhooks, IP allowlisting, request validation and quota enforcement on every exposed endpoint.

Audit logging

Every prompt, retrieval, tool call, model version and human override is logged with a trace ID, so any output can be reconstructed months later.

Data isolation

Per-tenant separation at the storage, index and key level for multi-entity groups and regulated environments.

Secure prompt handling

System instructions are server-side, user content is treated as untrusted input, and we test against prompt-injection and tool-abuse patterns.

PII protection

Detection, masking or tokenisation of personal data before it reaches a model, with configurable redaction policies per field.

Human approval workflows

High-impact actions — payments, refunds, contract sends, record deletion — route to a named approver instead of executing autonomously.

Monitoring & anomaly detection

Alerting on unusual tool usage, cost spikes, refusal rates and quality regressions.

Rate limiting & abuse control

Per-user and per-tenant throttles, spend caps and circuit breakers so a runaway loop cannot become a runaway invoice.

Secure deployment

Private networking, secrets in a managed vault, immutable builds, dependency scanning, and infrastructure as code.

FAQ

Questions enterprise buyers ask us first

What is an AI agent, in business terms?
Software that is given an objective rather than a script. It uses a language model to decide which action to take next, calls your systems to gather information or make changes, and repeats until the objective is met or it decides a human should take over. The practical difference from a chatbot is that an agent changes state in your systems; a chatbot mostly returns text.
How is an agent different from a chatbot?
A chatbot answers. An agent acts. A support chatbot tells a customer how to request a refund; a support agent checks the order, validates it against your refund policy, issues the refund through your payment provider, updates the CRM and emails a confirmation. The engineering difference is tool access, permissions and approval gates.
When should we not use an agent?
When the process must be deterministic, when errors are unrecoverable and cannot be gated behind approval, when volume is too low to justify the build, or when the underlying data is not reliable enough for any system to reason over. We will tell you during assessment if your case falls into one of these.
How do you stop an agent doing something damaging?
Layered constraints: read and write tools separated, least-privilege credentials per tool, hard step and spend caps, idempotency on writes, and a mandatory human approval gate for any irreversible action — payments, refunds, deletions, external sends. Plus a full trace so anything that does go wrong is explainable.
What does AI agent development cost?
A single-workflow agent with two or three integrations typically starts around $15,000–$25,000. Multi-workflow agent platforms with a shared tool registry, approval framework and observability run to $100,000+. You get a fixed price and delivery date before signing.
How long before it is live?
A scoped proof of concept in 3–4 weeks. A production agent handling one workflow end to end, typically 8–12 weeks including integration and security testing.
