Qgosu is a free quote and estimate management platform built for solopreneurs, freelancers, and small business owners. Unlike traditional invoicing tools that rely on spreadsheets or complex form-based editors, Qgosu uses a WYSIWYG approach: you edit your estimate directly on the final document, with no preview switching needed. What you create is exactly what your customer receives.
Why Qgosu?
Most quoting tools force you to fill out long forms before seeing the result, then break formatting when you export to PDF. Qgosu eliminates both problems by making the editing screen identical to the final output. Add line items, attach photos, drag to reorder — and your PDF is instantly ready, with logo and seal included.
Designed for the modern small business owner who needs to send professional quotes from anywhere, Qgosu offers a generous free plan with no time limits, plus advanced features for businesses ready to scale.

Stop guessing. Start growing. Your entire e-commerce business on one screen.
Running an online store usually means drowning in tabs. You log into Shopify for sales, Stripe for revenue, Meta Business Suite for ads, and Buffer for social posting. You have data everywhere, but no clear path to growth.
Cortexcart Insight Dashboard solves this fragmentation by centralizing your entire tech stack into a single, AI-driven operating system. It connects directly to your store (Shopify/WooCommerce), your bank (Stripe/QuickBooks), and your marketing channels (Facebook/Instagram/X/TikTok) to give you a real-time pulse on your business.
Unlike standard dashboards that just show charts, Cortexcart acts as your 24/7 AI Data Analyst. Powered by Gemini AI, it analyzes cross-platform correlations to answer questions like "Why did my conversion rate drop yesterday?" or "What is my true profit after ad spend?" with plain-English strategies.
Key Capabilities:
🤖 AI Analyst: Chat with your data. Get instant marketing plans, churn analysis, and revenue optimization tips without hiring a data scientist.
