**Subject:** Regarding your recent request: Adding an e-commerce store Hi [Client Name], Thank you for your email. Adding an online store is an exciting step, and it's a great sign for your business that you're ready to start selling directly through the site. An e-commerce store with 50 products and a custom checkout flow falls outside our current agreement. The original scope covers a 5-page informational WordPress website with standard contact forms, and the store is a significant addition in design, development, and testing. We'd be glad to take this on as a separate phase. The estimate is $2,500 and about two weeks of additional development time from approval. That timeline means we can't deliver by this Friday, but we can keep the 5-page site on its original schedule so you can launch it while the store is built out. If you'd like to go ahead, reply to confirm and I'll send over a formal estimate for your approval. Once it's signed off, we can schedule the work and get started right away. Best regards, [Your Name] I placed the two-week timeline directly against the Friday deadline so the client sees the gap up front. If you'd rather make the store phase launch-ready by Friday with a reduced scope (say, 10 products and standard checkout), I can add that as an alternative option.
