Why Maconomy's job-and-task hierarchy — carrying budget, time, expense, WIP, billing, and revenue as one structure — dissolves into distributed D365 constructs, and what that means for every design decision that follows.
Deltek Maconomy is a professional-services ERP where the job, not the ledger, is the centre of gravity. A job and its task hierarchy carry budget, time, expense, WIP, billing rules, and revenue recognition as one continuous structure.
The most distinctive structural feature of Maconomy — and the one with the fewest single D365 equivalents — is the job. A job in Maconomy is not merely a project identifier. It is the primary object around which the entire application organises professional-services delivery:
The playbook establishes five principles that protect every design decision. They are not aspirational; they are the test that any proposed mapping must pass.
The target architecture includes a formal decision test. This matters because selecting Project Operations changes the operating model, not merely the feature list.
A Maconomy migration does not begin with "Maconomy 2.x." It begins with a precise inventory of components, each with its own version, compatibility, and migration implication.
Three structural differences dominate programme effort. Naming them gives the team a shared frame for every subsequent conversation.
Underneath the structural differences, Maconomy and D365 share the same four-step pipeline that every transaction travels:
Every discovered object receives a primary disposition that determines its target and workstream ownership:
Job decomposition is the defining design workstream. Every active job must be classified into an approved archetype, its task hierarchy decomposed into scheduling, charging, billing, and accounting purposes, and its billing and recognition policy rebuilt from intent.
Maconomy and D365 Finance both achieve project-to-cash accounting. They do it through different structural choices, and a migration is the work of re-projecting one set of choices onto the other.
