Abstract:
Small and Medium Enterprises (SMEs) are important in the local as well as global
economy. However, they face challenges in managing customer communication,
sales operations, and inventory due to limited resources and the high cost of advanced
technologies like Artificial Intelligence (AI). Most large-scale entrepreneurs
use AI-driven solutions such as chatbots and virtual assistants to automate their
business operations. However, these systems are too generic and too expensive,
and they require technical expertise to manage. Therefore, such expensive methods
are unaffordable for small business owners. This research proposes an AI
framework for automated creation of customized business agents for small enterprises
using Large Language Models (LLMs) and Natural Language Processing
(NLP), enabling small business entrepreneurs and solo digital entrepreneurs to
create AI agents that meet their specific requirements without any programming
knowledge. The system offers a dual-agent architecture consisting of a business
owner agent and a customer agent. Together, these agents support tasks such as
responding to customer inquiries, handling business updates, retrieving businessspecific
knowledge, and generating operational insights. Unlike existing solutions
that require technical expertise or lack customization, this framework uniquely
combines zero-code deployment, dual-agent role specialization, and automated
Retrieval-Augmented Generation (RAG) synchronization. The proposed methods
involved dataset preparation, business-specific knowledge extraction, promptengineering
pipelines, agent design, and RAG integration. Several LLMs and
different vector databases were compared to select Llama 3.2 as the most suitable
LLM and Qdrant as the vector database. The system was evaluated against
n8n, a widely adopted workflow automation platform commonly used by SMEs
for chatbot deployment, using an e-commerce dataset. Experimental results show
the proposed framework achieved a normalized average score of 0.70 across evaluation
metrics (BLEU: 0.590, ROUGE-L: 0.664, BERTScore: 0.854) compared
to 0.076 for the n8n baseline (BLEU: 0.0105, ROUGE-L: 0.139, BERTScore:
0.078). Overall, the proposed AI framework enhances SME productivity by automating
repetitive communication tasks and enabling real-time decision-making,
with potential to reduce operational costs by 20–30% while providing 24/7 customer
support.
