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.

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

A person decides: Refunds, and any customer who is clearly unhappy
Sales research agent
Before each call, pulls the account history from your CRM, reads the prospect's website and news, and writes a one-page brief with talking points.

A person decides: The rep decides what to use. Nothing is sent to the prospect
Finance operations agent
Matches invoices to purchase orders and payments, chases missing documents by email and prepares journal entries for review.

A person decides: Posting entries and anything above your approval limit
Document processing agent
Reads contracts, forms and shipping documents, pulls out the fields you need, checks them against your rules and routes anything unusual.

A person decides: Only the exceptions it cannot resolve
Internal helpdesk agent
Answers staff questions from your actual policies and handles simple IT and HR requests, like password resets or leave balances, through your existing tools.
Uses
Ticketing system
Identity provider
Intranet
A person decides: Admin-level access changes
Developer and QA agent
Reviews pull requests, writes test cases from user stories and turns vague bug reports into clear tickets with steps to reproduce.
Uses
Git repository
Issue tracker
CI pipeline
A person decides: Engineers review and merge every change
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.
01
AI Agent Strategy & Use-Case Selection
We look at your processes with you and pick the tasks where an agent will pay for itself, and the ones where a simple automation would do the job better.
Test suites built from your real cases, permission limits, spending caps and a full log of every step, so you can see exactly what the agent did and why.
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.
Level 1
Suggest
The agent prepares the work and a person carries it out. A safe place to start for anything customer-facing.
Level 2
Act with approval
The agent does the work, then waits for someone to click approve before anything leaves the building.
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.
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
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
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
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
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
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.
Technology
Models, Frameworks and Tools We Use
We pick the stack for each agent based on your systems, your data rules and the budget per task.
Why Companies Choose Infilon for AI Agent Development
Software engineers first
We have been building web, mobile and ERP software since 2009. Most of the hard work in an agent project is integration and testing, which is what we do every day.
Not tied to one AI provider
We test GPT, Claude, Gemini and open-source models on your task and recommend the one that gives the best result for the cost.
Straight answers about fit
If a fixed workflow, a report or a simple chatbot would solve the problem, we will say so. Not every task needs an agent.

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.
