About Size the Market
Size the Market is a competitive pricing intelligence platform that monitors competitor prices in real-time across more than 1,000 e-commerce sites. Built by pricing intelligence company Advisable, it uses machine learning to match products across catalogs with 99%+ claimed accuracy, alerts teams to price and stock changes, and helps brands enforce MAP/MSRP compliance across retailers and marketplaces.
Pros & Cons
Pros
- Free forever plan lets small sellers track 5 products against 3 competitors at no cost
- Transparent self-serve pricing across six tiers, from $49/mo entry plan to enterprise
- ML-powered product matching with 99%+ claimed accuracy reduces manual catalog mapping
- Covers both retailer use cases (repricing, competitor tracking) and brand use cases (MAP/MSRP compliance, unauthorized seller detection)
- Real-time alerts for price and stock changes plus promotions tracking with historical data
- Free public tools (MAP, ROI, CPI calculators, competitor directory) add value beyond the core platform
Cons
- API access is gated behind the Business plan at $449/mo, pricier than some competitors' API entry points
- Dynamic pricing requires at least the Standard plan ($199/mo)
- Newer entrant with less market track record than established players like Prisync or Price2Spy
- Free and Discovery tiers cap competitors at 3-5, limiting usefulness in crowded categories
- Pricing displayed inconsistently in USD and EUR on the site, which can cause billing confusion for international buyers
