If you're standing up a SaaS stack for a e-commerce & online stores business from scratch, here's the order that works best:

1. Start with the customer-facing tools. CRM and email come first because they directly affect revenue. Get these running before anything else, even if it means delaying internal tools by a week or two.
2. Add operational tools next. Project management, help desk, and team communication go in second. These improve productivity but don't directly drive revenue, so they can wait until the customer-facing stack is solid.
3. Layer specialty tools last. Industry-specific integrations, analytics, and edge-case workflows go in last. These produce the biggest workflow gains but also the most setup complexity. Don't tackle them until the foundation is stable.

Total stack cost for e-commerce & online stores businesses typically lands between $200-$800/month depending on team size. That's the realistic range for a small business, not the ceiling. If you're spending more, audit each tool against the questions in our SaaS sprawl audit guide. If you're spending less, you're probably under-tooled and your team is doing manual work that could be automated.
