LLM Workflow Automation: Replacing 14 Manual Processes with One AI Platform

The Situation

A mid-sized D2C e-commerce company (₹180Cr ARR) had 14 manual processes consuming 1,200+ hours per month across teams:

• ▸Finance: reconciling 3 payment gateways, generating P&L summaries
• ▸Operations: supplier communication, inventory reorder decisions
• ▸Marketing: weekly performance reports, ad copy refresh, influencer brief writing

Each process had a human doing largely mechanical, rule-based cognitive work — exactly what LLMs excel at.

The Platform We Built

A workflow automation platform with three layers:

Trigger Layer

HTTP webhooks, scheduled cron jobs, and event streams (Kafka) trigger workflows. Each trigger carries structured context that flows into the AI processing layer.

AI Orchestration Layer

We use a router that dispatches to the right model based on task type:

• ▸Claude 3.5 Sonnet: Long-document analysis, report writing, nuanced judgment calls
• ▸GPT-4o mini: High-volume classification, data extraction, structured output generation
• ▸Claude Haiku: Simple transformations, formatting, low-latency responses

class WorkflowRouter:
    def route(self, task: WorkflowTask) -> str:
        if task.type in ["report_generation", "document_analysis", "judgment"]:
            return "claude-3-5-sonnet-20241022"
        elif task.type in ["classification", "extraction"] and task.volume > 1000:
            return "gpt-4o-mini"
        elif task.latency_requirement_ms < 500:
            return "claude-haiku-4-5-20251001"
        return "claude-3-5-sonnet-20241022"  # default

Integration Layer

Pre-built connectors for Shopify, Razorpay, Google Sheets, Slack, WhatsApp Business, and email. Custom connectors via REST API template.

Three Flagship Workflows

Workflow 1: Weekly Business Intelligence Report

Aggregates data from 8 sources → Claude analyzes trends → generates 15-page executive report with insights, anomalies, and recommendations → delivered to leadership every Monday 8 AM.

*Replaces: 18 hrs/week of analyst time*

Workflow 2: Supplier Communication Agent

Monitors inventory levels → when reorder point is hit, drafts purchase orders with negotiation context from historical pricing → sends via WhatsApp Business API → updates ERP on confirmation.

*Replaces: 6 hrs/day of procurement team work*

Workflow 3: Ad Creative Refresh

Every Monday, analyzes previous week's ad performance → identifies underperformers → generates 20 replacement copy variants per ad set → sends for human approval → auto-publishes approved ads.

*Replaces: 12 hrs/week of performance marketing team*

Results

ROI achieved in month 2. The team was redeployed to higher-value strategic work.
