Requirement evaluated: The system must support dynamic, non-linear approval and contribution routing in which the chain of participants is not fully defined at invoice intake and can be extended mid-flow by adding ad-hoc contributors such as project managers, superintendents, and contract owners without restarting the workflow from the beginning. This directly addresses the buyer's stated reality that they do not know upfront who needs to weigh in, and their current sequential tool forces a full restart on any early-stage rejection.
For a multi-location construction company whose PMs and superintendents cannot predict at intake who needs to weigh in, Stampli offers two complementary mechanisms. First, its dynamic workflow mode has Billy AI suggest approvers based on historical patterns across vendor, requestor, location, and invoice type, and users can override or adjust those suggestions as needed; this directly addresses the unpredictable-chain problem. Second, and more important for occasional contributors, Stampli's collaboration hub turns each invoice into a communication thread: any user can tag a teammate (a PM, a superintendent, a contract owner) …
