Large fixed-price software build with broad PRD — avoid or negotiate milestones?
I’m looking at a fixed $7K Upwork job where the client attached a detailed PRD for a serious product: full-stack app, AI workflows, approval/audit system, payments, document handling, third-party integrations, and external data-source automation.
The client seems legitimate, but the posted fixed budget feels too low if it is meant to cover the entire PRD. My concern is whether applying creates the expectation that I accept the whole scope for that amount.
What surprised me is that the top boosted proposals are around 250+ Connects. Is that normal for this kind of job? Are people treating these as high-upside leads and planning to negotiate scope later, or are they actually willing to take the whole thing at the posted fixed price?
How do you handle this?
Do you avoid these jobs, or apply and treat the budget as a starting point for milestone negotiation? Is it normal to propose a paid discovery/architecture milestone first? How do you make that clear without wasting a lot of unpaid time?
Thanks in advance — I’m trying to understand the norm here before I spend time writing a serious proposal.
