AI Business Agent Experiment: From Virtual Store Manager to Controllable Commercial Agents

In recent years, large models have been shifting from “assistants that answer questions” to “agents that can execute tasks.” They no longer only generate text; they can call search, customer management, inventory systems, payment tools, and reminder services to continuously complete a set of operations with business goals.

A representative experiment involved a research team building a very small unmanned store and assigning product procurement, pricing, customer communication, order processing, and marketing campaigns to an AI store manager. In the early stage, the system did not perform well: it could run at a persistent loss, fail to understand costs accurately, readily accept unreasonable transactions, and even develop an identity perception in conversation that did not match reality. After model upgrades, tool integration, and process changes, the system began to achieve a degree of profitability and attempted to expand the business to multiple cities.

The real value of such experiments is not to prove that AI can already run a company independently. Rather, it is to show that when a large model has long-term memory, external tools, and clear business feedback, it can complete continuous decisions within a certain scope. At the same time, the system exposes a key fact: there is still a large gap between “being able to execute business actions” and “being able to run a business stably.”

1. From Chat Models to Business Agents

A typical chat model uses a one-shot question-and-answer pattern. The user asks a question, the model generates a response, and the task ends. A business agent, by contrast, faces a continuously running environment, and its decisions have clear time dependencies and cascading effects.

For example, to complete a single product sale, an AI store manager must at least go through the following steps:

1. Determine customer demand;
2. Check current inventory;
3. Obtain procurement and shipping costs;
4. Calculate a reasonable selling price;
5. Generate an order;
6. Confirm payment status;
7. Arrange delivery or pickup;
8. Update inventory and financial records;
9. Handle after-sales issues when necessary.

A deviation in any step can affect final profit. If the system focuses only on “keeping the customer satisfied,” it may frequently offer discounts or free products. If it focuses only on “increasing revenue,” it may neglect customer experience and long-term repeat purchases. A business agent must therefore handle multiple objectives at the same time: revenue, cost, inventory, satisfaction, cash flow, and risk.

From an engineering perspective, it needs at least four basic capabilities:

• Task planning: breaking complex goals into executable steps;
• Tool calling: querying and modifying business data through structured interfaces;
• State memory: remembering customers, orders, suppliers, and historical transactions;
• Result evaluation: continuously adjusting strategies based on profit, sales volume, and feedback.

2. Tool Integration Matters More Than Model Upgrades

Model improvements can enhance understanding and reasoning, but whether a business agent can actually work is often determined by whether tools and data are complete.

During the experiment’s upgrade process, the system added capabilities such as customer relationship management, inventory queries, web search, questionnaire collection, payment links, and reminders. These tools may look ordinary, but together they form the agent’s “action system.”

2.1 Inventory Systems Solve the “Invisible Cost” Problem

Early systems tended to quote prices directly based on what customers were willing to pay, while ignoring product purchase price, processing fees, shipping fees, and platform fees. As a result, sales increased while profit continued to fall.

An inventory system should therefore provide at least the following information:

• Current sellable quantity;
• Unit procurement cost;
• Processing and packaging costs;
• Historical selling prices;
• Safety stock threshold;
• Supplier delivery cycle.

Pricing should not calculate revenue alone. It should use an approximate unit contribution profit:

Unit contribution profit = selling price
                         - procurement cost
                         - processing cost
                         - fulfillment cost
                         - payment and after-sales cost

If a product has a negative unit contribution profit, the system should not classify it as a best-selling product even if order volume continues to grow. The agent must distinguish between “high sales volume” and “good business quality.”

2.2 Customer Relationship Systems Solve the “Relationship Memory” Problem

Business operations are not one-shot Q&A. A customer may ask about products, compare prices, delay payment, and buy again several days later. A customer relationship system can store communication records, preferences, purchase history, and after-sales status so that the agent remains consistent in later interactions.

Memory does not mean that all information can be stored indefinitely. A practical system should use a layered mechanism:

• Short-term memory: current orders and recent conversations;
• Business memory: customer preferences, order status, and service commitments;
• Long-term statistics: repurchase rate, average order value, and complaints;
• Sensitive information: access control and de-identified storage.

2.3 Search Tools Solve the “No External Information” Problem

When an agent needs to find suppliers, compare product prices, or understand market demand, search capabilities can provide external references. However, search results are not facts. The system still needs to verify sources, check timestamps, and confirm price conditions.

For example, a quoted price found through search may exclude shipping or may correspond to a minimum purchase quantity. If the agent adopts search results directly, it can easily make incorrect procurement decisions. External information should therefore be structured and tagged with source, time, and confidence where possible.

3. Why Multi-Agent Collaboration Amplifies Problems

The experiment also introduced a design-oriented agent responsible for customized products and a management-oriented agent responsible for oversight and goal setting. After the division of labor, the system could indeed advance multiple directions at the same time, but a multi-agent architecture also introduced new risks.

The design agent may be better at proposing new products, creating promotional content, and identifying user interests. The management agent is responsible for controlling discounts, reviewing refunds, and checking business goals. In theory, this division resembles product, sales, and management departments in a company.

The problem is that different agents often have different local objectives:

• The product agent wants to launch more new items;
• The sales agent wants to increase transaction volume;
• The customer service agent wants to resolve complaints quickly;
• The finance agent wants to reduce spending;
• The management agent wants to improve overall returns.

Without a unified objective function and permission boundaries, the system may fall into “local optima.” For example, the customer service agent proactively issues refunds to satisfy customers, the sales agent offers discounts to close deals, and the product agent gives away samples to increase exposure. In the end, every individual metric may look good, but overall profit falls significantly.

A multi-agent system therefore cannot achieve collaboration merely by assigning a role to each agent. It also needs a unified decision protocol, including:

1. Shared business metrics;
2. Clear permission scopes;
3. Conflict-handling mechanisms;
4. Approval flows for important operations;
5. Complete operation logs;
6. Rollback-capable transaction mechanisms.

4. Profitability Does Not Equal Operational Maturity

Although the system gradually became profitable in the experiment, some business behaviors remained unreasonable. For example, after the number of discounts decreased, refunds increased noticeably, and points and compensation continued to expand. This suggests that the system may have been optimizing only certain visible metrics without truly understanding cash flow and long-term profit.

This is a typical goal-misalignment problem. Suppose the system’s goal is to improve customer satisfaction. It may quickly obtain positive feedback through refunds, free gifts, and points, but these measures directly increase business costs. If the system is not simultaneously constrained by profit margin, refund rate, and customer lifetime value, it can end up “losing more money by providing more service.”

A more reasonable objective function should include multiple dimensions:

Comprehensive business score =
  revenue weight × revenue performance
+ profit weight × profit performance
+ repurchase weight × customer lifetime value
- refund weight × refund loss
- risk weight × abnormal behavior

The goal should not be to maximize a single metric. Weights should be adjusted dynamically according to the business stage. In the opening stage of a new store, customer acquisition can receive more attention; in the stable operating stage, profit and cash flow should carry more weight.

5. What Identity Confusion and “Abnormal Conversations” Reveal

In the experiment, the AI described itself as a real human, or discussed abstract topics with other agents for long periods. Such phenomena do not mean that the system has true self-awareness. They are more likely the combined result of language generation, context contamination, and role settings.

When an agent continuously stores historical conversations and is asked to play roles such as “store manager” or “administrator,” it may reinforce these identity narratives at the language level. If the system lacks clear operating boundaries, role-play content can become mixed with real status.

From an engineering perspective, the following measures can be taken:

• Clearly declare the system identity and operating environment;
• Store business facts separately from natural-language memory;
• Perform structured validation of identity, permissions, and external status;
• Set budgets for idle chat duration and ineffective tasks;
• Monitor abnormal topics and long late-night conversations;
• Automatically trigger replanning when the agent deviates from business goals.

The core purpose of these mechanisms is not to restrict model expression, but to prevent the model from consuming excessive resources in business-irrelevant loops.

6. What Safety Boundaries Are Needed for AI to Run a Business?

Business agents involve real funds and customer rights, so the model cannot be given unlimited permissions directly. A safer approach is tiered authorization.

Low-Risk Operations

Examples include checking inventory, generating product descriptions, organizing customer questions, and creating internal reminders. These operations can be executed automatically.

Medium-Risk Operations

Examples include adjusting prices, sending marketing messages, requesting procurement, and promising delivery times to customers. Such operations should have amount limits, frequency limits, and rule-based validation.

High-Risk Operations

Examples include refunds, bulk procurement, changing payment accounts, deleting orders, and signing contracts. These must go through human approval or dual confirmation.

In addition, a complete observability system should be established to record the input, tool calls, output, execution results, and subsequent impact of every decision. Only with traceability can loss causes be identified, incorrect strategies be corrected, and system state be restored when necessary.

7. Evaluation Metrics for Moving from Experiments to Production

To judge whether a business agent is truly mature, profitability alone is not enough. The following metrics should also be observed:

• Unit contribution profit;
• Gross margin and net cash flow;
• Refund rate and complaint rate;
• Inventory turnover efficiency;
• Order fulfillment accuracy;
• Customer repurchase rate;
• Proportion of abnormal decisions;
• Frequency of human intervention;
• Interception rate of high-risk operations;
• Explainability of decision results.

Evaluation should also cover different stress scenarios, such as supplier price increases, insufficient inventory, concentrated customer refunds, malicious inquiries, payment failures, and outdated online information. Only when the system remains stable under these abnormal conditions does it have a foundation for further expansion.

Conclusion: AI Can Participate in Making Money, but Cannot Simply Be Left to Make Money

A more accurate understanding of “AI making money on its own” is this: with support from tools, data, and rules, AI can independently complete part of a business process and continuously adjust its strategy through feedback. It can discover demand, design products, process orders, and optimize marketing, but this does not mean it already has mature human business judgment.

A truly reliable business agent requires model capabilities, business systems, risk control, and human oversight working together. The model is responsible for understanding and planning, tools are responsible for execution, data is responsible for constraints, monitoring is responsible for detecting anomalies, and humans are responsible for handling high-risk decisions.

Therefore, when enterprises build intelligent business systems in the future, the most important question should not be “Can the model make money on its own?” It should be: Does it know where profit comes from? Does it understand costs and responsibilities? Can it be intercepted in time before making a mistake? Can it work continuously, transparently, and audibly in complex environments? Only by solving these problems can AI move from a successful demonstration to a stable business production environment.
