Overview
Migrating from a Payroll Automation platform to Crelate is an atypical pairing because Crelate is a recruiting ATS and CRM, not a payroll system. The migration scope is bounded by this reality: employee records (names, addresses, titles, departments, employment status) map to Crelate's Person or Candidate records, and org structure maps to Crelate's organizational hierarchy. Compensation histories, payroll runs, tax withholdings, benefit deductions, garnishment orders, and PTO balances have no native Crelate equivalent and cannot migrate into the ATS data model. We extract the transferable subset from the source via API, validate against Crelate's schema, and load through Crelate's data import tooling. We deliver a written inventory of every non-migratable object so your HR and payroll teams can plan the downstream handling of compliance-sensitive payroll data.

Object mapping
Each row shows how a Payroll Automation object lands in Crelate, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Payroll Automation
Employee
Crelate
Person / Candidate
1:1Employee records from the payroll system map to Crelate Person or Candidate records depending on the destination's object model configuration. Core fields that transfer: full name, preferred name, home address, work email, work phone, employment status (active, terminated, on leave), hire date, and termination date. SSN, bank account details, and tax withholding elections do not migrate because Crelate has no fields for this data and it is not appropriate to store in an ATS. We extract from the source payroll API at the employee record level and map to Crelate's Person or Candidate standard fields.
Payroll Automation
Org Structure
Crelate
Organization / Hierarchy
1:1Departments, cost centers, job titles, and reporting hierarchies from the payroll system map to Crelate's organizational structure if the destination includes an organizational hierarchy module. Job titles from the payroll source become the candidate's most recent job title in Crelate. Manager-employee relationships migrate as candidate-to-placement or candidate-to-client relationships depending on whether the destination org is a recruiting client or a candidate. We resolve the manager reference by matching the manager's employee ID or email to a Crelate Person record.
Payroll Automation
Employee Custom Fields
Crelate
Candidate Custom Fields
lossyAny custom fields on the employee record in the payroll system (certification types, skills tags, security clearance levels, union affiliation) map to Crelate's custom fields on Person or Candidate. The customer defines which custom fields are relevant for recruiting continuity during scoping. Fields containing payroll-specific data (salary bands, pay grades, equity holdings) are flagged as non-migratable and noted in the delivery documentation.
Payroll Automation
Terminated Employees
Crelate
Person / Candidate (inactive)
1:1Terminated employees from the payroll system migrate to Crelate as inactive or archived Person records to support re-hire eligibility and internal mobility programs. The termination date from the payroll source becomes the Person's end date or a custom termination_date field. We preserve the full tenure history (hire date through termination date) to support background check re-verification and institutional knowledge tracking. Active employees migrate as active Crelate Person or Candidate records.
Payroll Automation

Crelate
Job / Position
lossyCrelate's Job object is a recruiting-specific record with no direct payroll equivalent. We do not create Jobs from payroll data because payroll systems do not track job requisitions, candidate pipelines, or hiring stages. If the customer wants to populate Job records with headcount-planning data from the payroll org structure, we discuss this as a custom configuration option during scoping. Standard scope excludes Job record creation from payroll migration.
Payroll Automation
None applicable
Crelate
Application / Pipeline Stage
lossyCrelate's Application and Pipeline Stage records represent the recruiting process for a candidate and have no payroll equivalent. These objects are not created during a payroll migration because they represent job-applicant relationships that do not exist in a payroll system. If the customer's migration scope includes populating Crelate's recruiting pipeline with historical job data from an HRIS that also served as a job requisition system, we scope that as a separate object set and apply different pricing.
Payroll Automation
Compensation History
Crelate
Not Migratable
lossyWage rates, salary changes, bonus schedules, equity compensation, and pay frequency are payroll-specific data with no Crelate field or object equivalent. Crelate's ATS data model does not include compensation fields. We flag this object as non-migratable and document it in the written inventory with a recommendation that the customer retain the compensation history in their payroll archive or move it to a dedicated HRIS that supports pay transparency and compensation benchmarking.
Payroll Automation
Payroll Runs
Crelate
Not Migratable
lossyPaycheck records, payroll run dates, pay period summaries, and employer-side payroll entries have no Crelate equivalent. The payroll run is a transactional record specific to the payroll processing domain. Crelate's recruiting and ATS model does not include payroll run history. We extract a payroll run summary (year-to-date gross, YTD taxes, YTD deductions) as a reference document during migration discovery, but this does not load into Crelate because there is no destination field.
Payroll Automation
Tax Withholdings and Filings
Crelate
Not Migratable
lossyFederal, state, and local tax withholding records, Form W-4 elections, tax jurisdiction assignments, and IRS filing history are compliance-sensitive payroll data with no Crelate analog. Crelate's data model is built for candidate relationship management and applicant tracking, not tax compliance. We do not migrate tax withholding records. The customer's payroll team or tax advisor retains these records in the payroll platform archive or a dedicated compliance document store.
Payroll Automation
Benefit Deductions
Crelate
Not Migratable
lossyHealth insurance elections, 401(k) contribution rates, HSA/FSA deductions, life insurance premiums, and voluntary benefit deductions are payroll-domain records that do not exist in Crelate's ATS schema. We flag benefit deduction records as non-migratable and document them in the written inventory with a note that benefit enrollment history is typically retained in the payroll platform's archive, a benefits administration platform (if separate), or an ERISA-compliant document store.
Payroll Automation
Garnishments
Crelate
Not Migratable
lossyChild support orders, tax levies, wage garnishment judgments, and voluntary wage deduction authorizations are legally enforceable financial obligations tied to an employee's payroll record. Crelate does not support garnishment records. These are non-migratable by design and must remain in the payroll system or be transferred to a subsequent payroll platform if the customer is also changing payroll providers. We document garnishment obligations in the written inventory with a recommendation to coordinate with legal counsel before payroll system decommissioning.
Payroll Automation
PTO Balances
Crelate
Not Migratable
lossyAccrued PTO, sick leave, and other leave balances are calculated and stored within the payroll system's leave management module. Crelate does not include a leave accrual or time-off balance tracking module. We flag PTO balances as non-migratable and note in the written inventory that leave balance carryover should be handled by the payroll team during the transition to a new payroll platform if the customer is also changing payroll providers. Crelate's ATS does not track time-off balances for employees.

Migration approach
Discovery and object scoping
We audit the source payroll platform's API and export capabilities to identify every migratable object. We focus on employee records, org structure (departments, cost centers, job titles, reporting hierarchies), custom employee fields, and terminated employee history. We identify payroll-specific objects (compensation, tax withholdings, benefit deductions, garnishments, PTO balances) and classify them as non-migratable. We document the complete object inventory in a written scope and confirm with the customer which employee fields are relevant for recruiting continuity before migration begins.
Crelate environment setup and schema validation
We validate the Crelate destination environment: confirm the subscription tier (Business at minimum), verify seat count, and identify the target object model (Person, Candidate, or custom Person configuration). We map source employee fields to Crelate standard fields and identify any custom Person fields required for employee-specific data that does not fit a standard field. We coordinate with the customer's Crelate admin to create any required custom fields before data import.
Data extraction from source payroll platform
We extract employee records via the source platform's API at the employee object level. We pull core fields (name, address, email, phone, hire date, termination date, employment status, job title, department, manager reference) and any custom fields scoped during discovery. We do not extract SSN, bank account details, tax withholdings, or compensation amounts into the migration workspace; these remain in the payroll platform's archive. We run a pre-extraction validation to confirm the employee count matches the expected scope.
Transform, deduplication, and manager resolution
We transform the extracted employee records to match Crelate's field schema. Deduplication logic uses email address as the primary key for active employees and name-plus-hire-date for terminated employees where email may no longer be active. Manager references are resolved by matching the manager's employee ID or email to a corresponding Crelate Person record that was created earlier in the transform pass. Any employee records with unresolved manager references are held in a reconciliation queue for the customer's HR admin to resolve.
Test migration and customer validation
We run a test migration into Crelate's test or sandbox environment using a subset of records (typically 10-20 percent of total employee count). The customer's recruiting lead and HR admin review the migrated Person records, verify that names, titles, departments, and org structure are accurate, and spot-check termination date and employment status fields. We correct any field mapping errors identified during validation before running the full production migration.
Production migration and written inventory delivery
We run the full production migration in a single pass after test validation sign-off. We load employee records into Crelate as Person or Candidate records in the correct organizational hierarchy. Each phase emits a row-count reconciliation report. Upon completion, we deliver the written inventory document that enumerates every non-migratable object (compensation history, tax withholdings, benefit deductions, garnishments, PTO balances, payroll runs), describes why each cannot migrate, and provides recommendations for separate handling by the HR and payroll teams.
