AI Agent Development Services for Work That Takes More Than One Step

We build AI agents that read your data, use your business systems and finish real tasks from start to end. They ask a person before anything important happens, and every step they take is logged.

Goal

Follow up on every invoice more than 30 days overdue

  1. Read: Pulled 23 overdue invoices from the ERP

  2. Check: Matched recent payments, 4 were already paid

  3. Draft: Wrote 17 reminder emails in your usual tone

  4. Ask: Held 2 large accounts for finance to approve

    Waiting for your approval
  5. Log: Added a note to each customer record in the CRM

The basics

What Is an AI Agent, and When Do You Need One?

An AI agent is software that is given a goal instead of a script. It works out the steps, uses the tools it is allowed to use, checks what came back and keeps going until the job is done or it needs a person.

That makes agents a good fit for work that is too varied for fixed automation but too repetitive to deserve a skilled person's full attention.

AI Agents We Build for Everyday Business Work

Each agent has one clear job, a short list of tools and a line it doesn't cross without a person. Here are some we are often asked about.

Support resolution agent

Reads the ticket, checks the customer's orders and account, and resolves routine requests such as address changes, resends and delivery questions.

Uses

  • Help desk
  • Order system

Services

Our AI Agent Development Services

From deciding which task to hand over to keeping the agent reliable after launch, we cover the whole job.

Custom AI Agent Development

Single-purpose agents built around one job in your business, with the instructions, tools and permissions that job actually needs.

Multi-Agent Systems

For longer processes, several specialist agents that hand work to each other, with a coordinating agent that checks the result before it moves on.

Learn more about Multi-Agent Systems

Tool & System Integration

We connect agents to your ERP, CRM, help desk, email and internal APIs, including through the Model Context Protocol (MCP), so they can do real work.

Agent Knowledge & Memory

Agents that look things up in your documents and remember the context of a case, so they don't ask the same question twice or invent an answer.

How it works

What Goes Into a Reliable AI Agent

The language model is only one part. Most of the reliability comes from everything we build around it.

  • Model

    The language model that reads the situation and decides what to do next. We pick it by testing, not by habit.

  • Instructions

    The agent's role, the rules it must follow and what a finished job looks like, written with the people who do the work today.

  • Tools

    The specific actions it may take, such as looking up an order or drafting an email. No tool, no access.

  • Knowledge & memory

    Your documents, policies and the history of the current case, retrieved when needed rather than guessed.

  • Guardrails

    Permissions, spending limits, approval steps and topics it must not touch, enforced in code rather than in the prompt alone.

  • Logs & evaluation

    A record of every step and tool call, plus tests that run on each change so quality doesn't quietly slip.

How much freedom should an agent have?

You decide, task by task. Most of our agents start at level 1 or 2 and move up only when the results show they can be trusted.

  1. Level 1

    Suggest

    The agent prepares the work and a person carries it out. A safe place to start for anything customer-facing.

  2. Level 2

    Act with approval

    The agent does the work, then waits for someone to click approve before anything leaves the building.

  3. Level 3

    Act and report

    It acts on its own within set limits and sends a daily summary of what it did and anything it skipped.

  4. Level 4

    Run on its own

    Fully automatic inside a narrow, well-tested lane, with alerts the moment something looks unusual.

Our process

How We Build and Launch an AI Agent

Agents fail in the details: the odd invoice format, the customer who replies in two languages, the system that times out. Our process is designed to find those details before your customers do.

  1. 1

    Map the task

    We sit with the people who do the job today and write down every step, every system they open and every exception they handle.

  2. 2

    Agree what success means

    We choose measures such as time per case, error rate and the share of cases handled without help, and build a test set from your past cases.

  3. 3

    Build a narrow first version

    One job, the fewest tools it needs, read-only access at first. Small agents are easier to trust, test and fix.

  4. 4

    Test on real cases

    We run the agent against hundreds of past cases, compare its work with what your team actually did and fix what it gets wrong.

  5. 5

    Roll out and watch closely

    It runs in shadow mode first, then with a small group, with dashboards and logs so you always know how it is doing.

FAQ

AI Agent Development FAQs

What is an AI agent?

An AI agent is software that uses a large language model to work toward a goal, not just answer a question. It can look things up, use tools such as your CRM or email, check its own results and decide what to do next, all within the permissions you give it.

How is an AI agent different from a chatbot?

A chatbot talks. An agent does the work. A chatbot might tell a customer how to change their delivery address, while an agent can check the order, update the address in your system, confirm with the customer and log what it did.

What kind of tasks are a good fit for an AI agent?

Tasks that take several steps, involve more than one system and need a little judgement, but follow a pattern your team could explain to a new colleague. Invoice follow-ups, ticket triage, document checks and research briefs are good examples. Tasks that are rare, high-risk or depend on relationships are usually not.

Is it safe to let an AI agent take actions in our systems?

It can be, if it is built carefully. We give each agent only the tools and permissions its job needs, require human approval for anything costly or irreversible, set spending and rate limits, and log every step. Most agents start by suggesting actions and only act on their own once the results have earned it.

How much does AI agent development cost?

It depends mainly on how many systems the agent connects to, how much freedom it has and how much testing the task needs. A focused agent for one job costs far less than a multi-agent system. After a short discovery phase we give you a fixed-scope estimate before development starts.

How long does it take to build an AI agent?

A first version working on your real data typically takes a few weeks. Getting it ready for production takes longer, because of integrations, security reviews and testing on past cases. We agree the timeline with you once the scope is clear.

Can an AI agent work with our existing ERP, CRM or legacy software?

Yes. If a system has an API, the agent can use it. If it doesn't, we can build a small integration layer or work through exports and scheduled imports. We have integrated with many ERPs over the years, including Cetec ERP.

Which AI agent framework and model do you use?

Whichever suits the job. We often use LangGraph, the OpenAI Agents SDK or the Claude Agent SDK, and connect tools through MCP. For the model, we compare two or three options on your task and choose on accuracy, speed and cost.

Tell us about the task you would hand to an agent

In a 30-minute call we can usually tell whether an agent is the right tool, what a sensible first version would do and which decisions should stay with your team.

Book a Call

Useful to have ready for the call

  • 1The task you would like an agent to take on
  • 2The systems people open to do it today
  • 3Roughly how many cases come in each week
  • 4Which decisions must always stay with a person

None of it is required. We can work it out together.
