An AI platform revolutionizing e-commerce with real-time price negotiations

About Haggle

Haggle is a B2B2C SaaS platform that brings the art of negotiation back to online shopping. Using AI-powered negotiation, it turns fixed e-commerce pricing into dynamic, real-time conversations between merchants and customers. Thereby boosting conversions, protecting margins, and creating a more personal buying experience.

Background

Most e-commerce experiences are built on static prices that either leave value on the table or miss opportunities to win the sale. Haggle set out to change that by enabling intelligent, guardrailled price negotiations at the moment of intent. By blending machine learning and behavioral analytics, the platform empowers sellers to optimize pricing strategies, while giving customers a sense of control and fairness in their journey

Client Challenge

Haggle had to be powerful without feeling complicated. Merchants wanted real control, product-level rules, customer tiers, and hard price floors. They also needed a setup that’s easy to understand. The negotiation widget had to drop into any storefront and look native, without slowing pages or breaking layouts. The engine needed to feel instant, even when lots of shoppers were negotiating at the same time.

We also built in protections so nobody can game the system; things like limits, bot checks, and strict floor-price enforcement to protect margins. And to prove it’s working, the platform clearly shows its impact, tracking conversion lift and incremental revenue across different setups, Shopify today, WooCommerce next, and CSV feeds with all their quirks.

Solution Offering

To address these challenges, we implemented the following solutions:

Merchant Dashboard Development: We designed a console that makes a complex pricing strategy feel simple. Merchants can onboard stores, set negotiation boundaries, assign products, and tailor behavior by customer segment, then use clear insights to fine tune what’s actually converting.

Negotiation Rule Engine: We built a flexible rules framework that translates business policies, minimums, discount bands, product-level constraints, tiered policies, and frequency limits into enforceable guardrails the AI must follow, protecting margins and brand consistency.

Embedding & UI Integration: We shipped drop-in components that inherit each storefront’s theme, stay responsive, and avoid script conflicts. The experience feels native and doesn’t interrupt checkout flow or page performance.

Real-time Negotiation Engine: We integrated NLP and reinforcement learning with backend services to power instant, chat-like bargaining. The engine reads buyer intent, proposes optimized offers, and adapts over time, while hard limits keep every deal within policy.

Performance & Scalability Optimization: To keep sessions snappy under load, we leaned on caching and containerized/serverless patterns. The architecture supports high concurrency with low latency, so negotiations feel human, fast, responsive, and reliable, even at peak traffic.

Analytics & Reporting Module: We engineered outcome-focused analytics that quantify negotiation impact: conversion lift, success rates, and per-product ROI. Merchants can see what’s working, iterate quickly, and tie gains back to specific rules or campaigns.

Security & Abuse Prevention: We implemented rate limiting, session validation, bot detection, and automated floor-price enforcement. Together, these controls prevent gaming the system and ensure every accepted offer stays within policy.

Platform Integrations: We built connectors and APIs for easy adoption, most notably a Shopify app, so merchants don’t need major backend changes. WooCommerce support is in progress, with webhooks enabling real-time event flow between systems.

Tiered Merchant Pricing & Licensing: The platform supports subscription tiers (free, premium, enterprise) aligned with scale and needs, negotiation capacity, advanced analytics, and enterprise features, so teams can start small and grow confidently.

Result

Haggle now gives merchants a reliable way to negotiate at scale. Shoppers get quick, natural back-and-forth on price without leaving the flow, and merchants keep full control with hard limits that protect margins. The platform stays responsive during peak traffic, and the analytics make the lift visible, showing where negotiations close faster, which rules perform best, and how much extra revenue they add.

With Shopify Live and more connectors on the way, Haggle turns a static “take-it-or-leave-it” moment into a conversation that wins more sales.
