According to the current definition of your “own remaining fee”, this can become negative if you have billed (sub) services yourself, but for which a subcontractor has not yet invoiced.

At the same time, it is inflated if there is a subcontractor invoice but you have not yet charged it yourself.

The “own remaining fee” should be independent of subcontractor fees. Because you may still receive your own fee for the service on a pro rata basis, even if it is now shown negatively.

It would be desirable if the actual “own remaining fee” was shown, which only applies to one's own services. Then I could compare it with “Planned Own Costs.”
