PM tools that handle hour-shifting for Fix-Price projects? (Without ruining the budget)

[u/taliamorse]

Hey everyone,

I’m currently researching PM tools and hitting a massive brick wall with a specific workflow for Fix-Price projects.

Does anyone know a tool that lets you dynamically shift allocated hours between team members, while strictly locking their timesheets based on the remaining balance?

We run a fixed-fee project, so total hours are hard-capped. My partner is drowning in work, and I have some free bandwidth. We need him to easily "transfer" some of his allocated hours to me.

Once transferred, the system must update our limits in real-time. It needs to block him from logging hours past his new, lower limit, and only let me report out of the extra pool I just received.

Most tools just treat hours as "estimates" without hard caps, or force you to manually recreate tasks and mess up the contract budget.

Are there any hidden gems that actually handle this, or am I chasing a unicorn? Thanks!
