Contractor Hub for Business is the service-provider app of the Contractor Hub platform, built for contractors, design offices, maintenance companies and suppliers who want new clients and professional tools to run their daily business from their phone, with Saad, an AI agent that gets tasks done with them inside the app. Receive real project requests from clients in your area, contact them directly, and manage your projects, quotes and documents with ease. Saad, your AI agent Talk to Saad or write to him, and he carries out what you ask inside the app while you watch on screen: • Raises a new tender with you step by step: field, specialties, location, description and the offers closing date. • Prepares quotations, invoices, contracts and technical proposals: adds, edits, reorders and duplicates items, and adds your products and the payment schedule. • Opens any screen in the app, any of your clients, and building material prices. • Finds service providers in the platform's directory and opens their profiles. • Speaks Arabic and English. Saad is available to every provider within a monthly allowance, with a larger allowance on Plus. Why Contractor Hub? • Projects in your area: browse client requests by specialty and city, and be the first to reach the client. • Tenders: raise your own tender, receive offers and choose the best one, or submit your offer on open tenders. • A professional profile that showcases your work: present your services, products, past work and credentials on a profile clients can see. • Ready-made document tools: create professional quotes, invoices, contracts and technical proposals as PDFs in minutes, and share them directly with your clients. • Client management (CRM): track every client and project in one place, from first contact to completion. • Instant notifications: get notified the moment a new project that matches your specialty is posted, so you never miss an opportunity. Professional document tools • Quotations: a formatted price quote with your line items, prices and terms, ready to send. • Invoices: compliant invoices with 15% VAT. • Contracts: contracting agreements with Saudi legal clauses, a payment schedule and signatures. • Technical proposals: detailed specifications per item, with photos.
