Is there software for online signature of estimates?

Question

Document flow

The essence is the signature of estimates. Full cycle - a month. First, let's say on the 1st-2nd of each month the estimate is approved / disapproved / and by a person1, then on the 3rd-4th day the other person does the same, then on the 5th day it is checked whether the estimate is approved / not approved. Now it's all offline. That is, if, for example, the manager wants to find out on the 15th where the estimate is, he goes to the place where, according to the plan, the estimate should be. But if a force majeure event occurs and the estimate is stuck at one of the previous stages, he will be able to find out where it is only by checking each previous stage. That is, there is no real-time tracking of the status and location of the estimate. The input of the program receives one or several documents - Estimate1. Is there specialized software for such tasks, the construction industry?
