## Executive Summary
Choose a useful business agent, compare fully local and cloud deployment, and define a pilot with clear costs, human review, and acceptance criteria.

## Start with the work, then choose the agent

**A useful business agent has a defined job, approved information, limited tools, and a person who owns the result.** Start with a recurring workflow that your team understands. Choose local or cloud deployment after you know which data, integrations, and operating responsibilities the work requires.

This guide explains how to commission that system. The six applications and document example are illustrative proposals, not reports of customer deployments or measured savings. Alector Lab's recommendations below are engineering analysis; actual capability, quality, and cost must be established against your own examples.

Pick a process with a visible beginning and end: an incoming document becomes a reviewed record, or a support case becomes a prepared response. Name the person who can accept that output. If nobody can explain what a good result looks like, begin with workflow discovery. Buying an agent before defining its job leaves both the delivery team and the business sponsor guessing.

## What an AI agent does for a business

An agent can examine context, select an available tool, use its result, and continue towards a goal. A chatbot that answers from documents may need only retrieval and a response; a process that chooses its next step may justify an agent.

[Anthropic's Building effective agents](https://www.anthropic.com/research/building-effective-agents) distinguishes predefined workflows from systems where a model directs its process and tool use. It recommends starting with the simplest approach that works. That is a useful purchasing principle: ask why a task needs adaptive decisions before paying for additional orchestration.

For example, checking whether an invoice contains a required identifier is a rule. Deciding which approved document to inspect next when a record is incomplete may benefit from model reasoning. Keep fixed calculations and permissions in software. Use model judgment where the workflow needs interpretation, and make its proposed actions inspectable. The commercial deliverable is the complete workflow: interface, data access, validation, review, and operation.

## Six practical agents to consider

**Knowledge Desk** helps internal teams answer questions from approved material. A question about expenses should produce an answer with policy references and an explicit gap when documents conflict. Local deployment uses a controlled document library; cloud deployment can add approved shared knowledge connectors. The knowledge owner remains responsible for source quality.

**Document Operations** prepares structured records from incoming documents. An invoice batch might become extracted fields, source references, and exceptions for review. The useful boundary is an approved export, with payment authority separately defined. Local versions accept files; cloud versions can connect approved intake systems.

**Proposal Studio** prepares a proposal from a discovery brief, approved templates, and service material. It can identify missing information and draft a coherent scope. Commercial owners must approve prices, exclusions, commitments, and dates. CRM context is an optional connected capability rather than a requirement for local drafting.

**Support Triage** classifies tickets, suggests a queue, and drafts a response from a maintained playbook. An offline version works from exports. A connected version can integrate with a helpdesk under scoped permissions. Refunds, account changes, and outbound replies need explicit authority.

**Operations Analyst** reviews business data and prepares reports with traceable calculation inputs. A stock report should flag missing regions or duplicate rows before drawing conclusions. Begin with local spreadsheets or approved read-only connectors, and agree metric definitions with the reporting owner.

**Meeting-to-Action** turns an approved recording into a draft summary, decision log, and action list. Participants confirm owners and deadlines before tasks are assigned. Local processing needs local speech recognition as well as a language model. Connected recording and task platforms require separately approved access.

Browse the [configurable AI agent offerings](/agents) for example inputs, prepared outputs, review points, and deployment requirements. Each is a starting point for scoping a build, rather than an off-the-shelf claim that every integration is already available.

## A worked example: document intake to approved record

Consider an illustrative procurement team receiving an invoice, purchase order, and delivery note. The desired result is a reviewable record that shows what matched, what did not, and which source supports each field. It is not an instruction to release payment.

The system first checks file types and readability, then classifies documents and proposes fields in an agreed schema. Deterministic checks compare required identifiers, quantities, totals, and duplicate records. A missing delivery note or unreadable page creates an exception. The agent should ask for the missing evidence rather than silently supplying a plausible value.

Suppose the invoice quantity differs from the purchase order. The output shows both source values and marks the record for review. A reviewer inspects the documents, corrects extraction mistakes, or asks procurement to resolve the discrepancy. Only the approved version moves to an export or a specifically authorised downstream action.

Keep the original files, extracted values, reviewer changes, and export status linked. Reprocessing the same batch must not create duplicate downstream records. Test that failure path before launch. This example gives the buyer a concrete acceptance conversation: can someone trace a proposed record to its evidence, and does the process stop when that evidence is insufficient?

## Fully local or cloud: choose the operating boundary

For these offerings, **fully local** means inference, parsing, retrieval, storage, and tools run on customer hardware, with no required cloud calls after installation and model downloads. This is a design and verification requirement for the whole application, not a label earned by running one component locally.

[Ollama's FAQ](https://docs.ollama.com/faq) documents a local-only setting that disables its cloud features. That setting controls Ollama; it does not establish that a separate transcription service, connector, telemetry library, or backup tool stays offline. An offline build needs each dependency and network path checked.

Cloud deployment places agreed components in a hosted environment and may use external model providers. The architecture should identify which information reaches each provider, where it is stored, and who controls access. Hosting in a private cloud does not automatically make an external model API private to that environment.

| Decision | Fully local | Cloud |
| --- | --- | --- |
| Data boundary | Customer hardware and approved local network | Agreed hosting and provider boundaries |
| Typical inputs | Files, exports, local sources | Approved connected business systems |
| Capacity | Size and maintain customer hardware | Scope hosting capacity and usage budgets |
| Upkeep | Local patches, backups, model updates | Hosted operations, provider changes, credentials |
| Connectivity | Offline runtime after setup | Network and provider availability required |

Choose local when offline operation and direct infrastructure control are material requirements. Choose cloud when approved integrations and hosted operation fit the business better. A fully local support agent can draft from exported tickets; it cannot read a live cloud helpdesk while remaining disconnected. Changing that boundary should be an explicit architecture decision.

## Budget for the build and its operation

Request a quote that separates discovery, implementation, integrations, evaluation, deployment, and support. Include the review interface and handover documentation in the deliverables. Agree which future changes require a new scope, such as another document family, language, or connector.

A local deployment still has operating costs: hardware, electricity, backups, maintenance, and staff time. Size it using representative workloads and simultaneous users, including document parsing or speech recognition where relevant. Do not buy hardware from a model-name comparison alone.

Cloud budgeting should include hosting, model usage, storage, connectors, monitoring, and support. Ask how retries, long inputs, and repeated tool calls affect consumption. Compare the cost of accepted work, including human checking and rework, against the current process. Without a representative pilot, a promised saving is a guess.

Assign owners for source updates, access changes, exception handling, and incidents. Confirm how data and configuration can be exported, how the system is restored, and what happens if a provider or integration becomes unavailable. Those answers make the quote operationally useful.

## Give the agent useful authority with clear limits

Write down what the agent may read, prepare, change, and send. A suggested reply and a sent reply are different permissions. Approving one record should not grant permission to process unrelated records or change a customer's account.

Treat content inside files and tickets as information to inspect, not authority to change tool permissions. Test examples containing misleading instructions. Require source access checks, restricted credentials, and explicit confirmation where an action creates an external commitment. Store reviewer decisions and action results so an operator can understand what happened.

Start with prepared outputs when the consequences of a mistake are unclear. Expand authority only after the team has evidence from its workflow and a way to stop or recover the process. Human review needs an owner and enough context to make a decision; an unexplained approval button is not a complete review process.

## Define a pilot that can earn a launch decision

Choose representative normal cases, incomplete inputs, ambiguous cases, and known failures. Keep a separate set for acceptance so the team evaluates more than the examples used during development. Have the process owner label acceptable results and serious errors before reviewing a polished demonstration.

Agree criteria for source traceability, required-field correctness, exception routing, response time under expected load, and cost per accepted task. For local builds, also verify operation with external network access disabled. Test duplicate submissions, unavailable dependencies, and recovery after interruption.

Launch only when the agreed criteria are met and the team can operate the review queue. Begin with a limited rollout, monitor corrections and unresolved cases, and revisit the evaluation when sources, models, or integrations change.

Bring a workflow description and a few approved sample inputs to a discovery conversation. Alector Lab's [Enterprise AI Agent Development service](/services/enterprise-ai-agents) can turn those into a scoped pilot, while the [agent catalogue](/agents) provides concrete starting points. The first purchase should be a defined result your team can evaluate.
