Most teams hear "payroll implementation" and picture a six-month project with a dedicated team. Here's what it actually involves when the integration is built on Workday's current framework.

There's an objection that comes up in nearly every conversation about bringing global payroll inside Workday. It's not about cost, or features, or whether the integration works. It's about bandwidth.

"We don't have the capacity for an implementation project right now."

It's a reasonable concern. Most people who've been through a Workday implementation remember what it took: months of scoping, a dedicated SI team, design sessions with ten people on the call, parallel runs, data migration, and a go-live that felt more like a launch than a configuration change. Global payroll implementation tends to conjure the same picture: a six-month timeline, a dedicated project team, and one more demand on people who are already stretched.

But the implementation they're imagining is based on how Workday global payroll integrations used to work. The way they work now is fundamentally different.

The old model: why implementation used to take six months

Until recently, integrating a global payroll provider with Workday required building a custom integration inside the Workday tenant using a method called PECI (Payroll Effective Change Interface). PECI is a scheduled, file-based integration that had to be built, configured, and tested by a certified Workday specialist — typically from an SI partner.
