Lost institutional knowledge
Your last payroll system admin just retired — and nobody else understands the PeopleCode tax rules.
Rising compliance risk
A single payroll error can mean six-figure penalties from state and federal agencies.
High internal cost to run payroll
Internal payroll processing eats four full-time employees and two servers you'd rather redeploy.
Oracle PeopleSoft → ADP Enterprise HR migration — your questions answered
How do you guarantee zero payroll downtime?+
Yes. We maintain your Oracle PeopleSoft environment as a fully operational backup system until multiple ADP payroll runs are validated. You never run a single live payroll on ADP until you're ready.
What about our custom PeopleCode tax calculations or benefit logic?+
Our senior engineers have done this before. We document every custom PeopleCode tax schema, non-standard benefit-accrual logic, and unique banking integration — then replicate it in ADP. Fixed scope means no surprises.
What if we miss a vendor renewal deadline?+
We keep your legacy system live under vendor support as long as your current contract is active. If the renewal lapses, our third-party support covers most operational issues while you finish the move. There is no forced big-bang cutover.
How long does a typical PeopleSoft to ADP migration take?+
Typical Enterprise migrations run 6–12 months with 3–5 senior engineers. Budget ranges from $150,000 to $1,500,000 depending on customizations and data volume. We give you a fixed price before you commit.
