Profit Bid is a cloud SaaS platform that helps ecommerce merchants and agencies optimize paid advertising for real profitability — not just revenue. While ROAS can look healthy even when margins shrink, Profit Bid focuses on POAS (Profit on Ad Spend): gross profit attributed to ads divided by ad spend. Connect stores like WooCommerce, Shopify, PrestaShop, Shopware, and OpenCart to Google Ads, Meta, TikTok, Microsoft, Pinterest, and Amazon Ads. Profit Bid calculates order-level profit with COGS, shipping, payment fees, and VAT, then sends profit-weighted conversion values to ad platforms — with automatic refund retractions when orders cancel. Smart A/C/X product labels sync to Google Ads so winners scale, borderline SKUs get optimized, and losers are excluded. Automated bid and budget rules, Shopping & PMax campaign setup, and AI Agent Proby provide daily POAS-driven recommendations you can approve or auto-apply. Plans from $14.99/month with a 14-day free trial at profit-bid.com.
