I need a professional, responsive website that lets my CPA firm sell services directly online and accept client files safely. The core of the build is an e-commerce flow where visitors can browse and purchase Accounting Consultations, Tax Filing Packages and Bookkeeping Services, then pay through a fully-secured gateway (Stripe, PayPal or another PCI-compliant solution you recommend). Alongside the store, the site must include a private client area where each buyer can log in, view their orders, and upload supporting documents. Uploaded files have to be encrypted in transit and stored behind authentication so our staff can review them from an admin dashboard. Key deliverables • Modern, mobile-friendly site design that matches existing firm branding • Service catalogue configured as products with variable pricing (hourly, tiered or flat-fee options) • Checkout workflow with SSL, fraud protection and automated receipts • Client portal with password reset, order history and secure document upload • Admin tools to add/edit services, download client files and export sales reports • Basic on-page SEO, Google Analytics integration and launch support • Short hand-off guide or recorded walkthrough so my in-house team can manage updates Acceptance criteria: checkout must pass a live payment test, file uploads must save successfully to the server with access limited to authenticated staff accounts, and page load time should remain under three seconds on a standard broadband connection. Tech stack is flexible—WordPress + WooCommerce, Shopify, or a custom framework are all fine—as long as security and ease of future maintenance are addressed. Source code and any design assets created during the project will be transferred to me at completion.
