Pre-built paycom data migration for HR, Payroll, Time, Benefits and Talent. REST API extractors with OAuth, multi-year pay-history streaming, deduction-code to Element crosswalks, HDL Worker.dat and FBDI Payroll Balance emitters, row-level reconciliation. Audit-ready evidence at every load.
The hard part isn't pulling JSON from a REST API. It's translating Paycom's single-database HCM/Payroll model into Fusion's Worker + Element + Balance + Distribution model without losing FLSA, IRS or ACA substantiation.
Paycom presents a unified HCM/Payroll data model — every employee, paycheck, time record, benefit enrollment and performance review in one database. That single-database design is Paycom's marketing differentiator but it shapes how the data has to come out. The Paycom REST API surfaces each domain (HR, Payroll, Time, Benefits, Talent) but the relationships between them — paycheck-to-time-card, deduction-to-benefit-enrollment, garnishment-to-court-order, W-2-to-paychecks-aggregated — have to be preserved through the conversion or downstream Fusion reporting breaks.
Every paycom data migration to Oracle Fusion has to bridge that gap without breaking the audit chain that links a GL journal line back to its original paycheck, time card and punch. Custom REST clients and one-off transformation SQL can do it — but every domain becomes a multi-week negotiation between HR, payroll ops, treasury and compliance teams. Syntra ETL replaces that with pre-built crosswalks refined across multiple Paycom conversions.
The same engine handles three deployment scenarios: full Paycom replacement (HR + Payroll + Time + Benefits + Talent → Fusion), Payroll-only migration with HR staying on Paycom for one more cycle (common when finance wants the AP/GL integration first), and the hybrid pattern where Talent stays on Paycom while Core HR and Payroll cut to Fusion.
The transformations Syntra ETL ships pre-built. No custom REST scaffolding, no multi-month bespoke conversion development.
Every Paycom deduction code walked, classified by tax treatment (Section 125, 401(k), HSA, FSA, post-tax, garnishment), and mapped to Fusion Element classification with Iterative Calc, Balance feeds and Costing auto-suggested.
Child support, tax levies, bankruptcy, student loans, creditor garnishments mapped to Fusion Involuntary Deductions with priority order, exemption rules and disposable-income calculations preserved.
Paycom's friendly multi-state UI translated to explicit Fusion Payroll Statutory Units and Tax Reporting Units per state, with locality-level setup for cities like NYC, Philadelphia, San Francisco.
Pay-history converted to Fusion Payroll Balance Initialization with YTD/QTD/MTD balances per employee per balance type — gross pay, FIT, FICA, Medicare, state tax, deductions, garnishments.
Beti employee-driven payroll audit events (employee verification timestamps, exceptions, manager overrides) preserved as evidence metadata against migrated paychecks for SOX continuity.
IRS W-2 and ACA 1095-C history preserved end-to-end: tax year, box totals, coverage months, employee dependents — IRS 4-year and ACA 3-year retention windows satisfied.
A repeatable load order that respects Fusion HCM/Payroll's data dependencies. Skip a step and your Worker load fails on missing PSUs.
Fusion enterprise structures, Payroll Statutory Units, Tax Reporting Units per state, legal employers, business units, COA segments, payroll definitions, payment methods configured via FSM. Everything downstream depends on this foundation.
Workers (HDL Worker.dat) with assignment history, jobs and positions, locations, departments, manager hierarchy. Loaded in dependency order — Workers before assignments, assignments before pay records.
Element setup (HDL Element-and-Element-Eligibility), deduction-code conversions applied, garnishments loaded as Involuntary Deductions with priority orders. Balance feeds auto-configured.
FBDI Payroll Balance Initialization for YTD/QTD/MTD balances per employee. Multi-year pay history archived for FLSA/IRS retention. Punch records and PTO balances loaded via HDL Time/Absence.
Open enrollment elections, dependents, beneficiaries (HDL Benefits), punch records and schedules (HDL Time), performance reviews, goals and succession (HDL Talent). Loaded after Workers exist.
Final delta replay, parallel-cycle reconciliation, sign-off pack (payroll register, W-2 totals, headcount, accrual balances — Paycom vs Fusion to the penny). Production payroll cut to Fusion.
A signed pack delivered at every load — and at final cutover. No reconstruction when auditors arrive.
Headcount per legal employer, gross/net pay per pay period per state — Paycom vs Fusion to the penny. Variances itemized and explained or zero.
YTD/QTD/MTD balances per employee per balance type — gross, FIT, FICA, Medicare, state tax, each deduction code. W-2 totals tie to YTD balances at year-end.
Active garnishments matched 1:1 across Paycom and Fusion with priority order, balance owed, payee, court reference number preserved.
Open enrollment elections, dependent coverage, beneficiary designations — count and content reconciled. ACA 1095-C coverage months tie.
Punch records and PTO balances reconciled per employee. FLSA 2-year supporting timekeeping detail preserved through migration.
Every hop signed and timestamped. Access logs preserved. Auditors get a pre-built pack instead of a 6-week reconstruction project.
Paycom data migration is the process of moving employee master, position history, paychecks (gross-to-net detail, deductions, garnishments, tax withholdings), W-2/941/1095-C history, punch records, PTO balances, benefits enrollments, performance reviews and talent data from a Paycom tenant into Oracle Fusion HCM/Payroll. The technical heart is two-fold: streaming structured data through the Paycom REST API with scoped OAuth, and converting the single-database HCM/Payroll model into Fusion's Worker + Payroll Element + Balance + Distribution model. Syntra ETL handles both with pre-built extractors, governed crosswalks for deduction codes and multi-state payroll, and Oracle-validated HDL Worker.dat plus FBDI Payroll Balance Initialization output.
The terms get used interchangeably, but the distinction is useful: paycom data migration is the end-to-end project (extract + transform + load + reconcile + cutover), while Paycom data conversion is the transformation layer specifically. Syntra ETL's Paycom data conversion engine ships pre-built rules for employee-id to person-number generation, deduction-code to Fusion Element-classification mapping, garnishment to Involuntary Deduction conversion, Beti audit preservation, multi-state Payroll Statutory Unit derivation and pay-history balance translation. These are rules that on a consultant-led project would otherwise eat 3–4 months of bespoke REST client and conversion-SQL development.
Paycom pay-history is the second-largest data volume in a Paycom data migration (after W-2/1095-C archives). A 1,500-employee tenant with 7 years of bi-weekly pay history produces roughly 270,000 paychecks plus detail rows for deductions, garnishments, taxes and accruals — millions of rows. Syntra ETL streams pay-history through the Paycom Payroll API in parallel (respecting REST rate limits), preserves the original Paycom paycheck-id, and stages to Parquet with hash signatures. For Fusion-target loads, pay-history is converted to Fusion Payroll Balance Initialization payloads with YTD, QTD and MTD balances per employee per balance type. For archive-target loads, paychecks stay queryable through the long-term Paycom archive for IRS 4-year and FLSA 3-year retention.
Yes. Paycom deduction codes are the rough equivalent of Fusion Payroll Elements — they drive every pre-tax, post-tax, employer-match and statutory withholding on the paycheck. Syntra ETL's Paycom converter walks every active deduction code, classifies by tax treatment (Section 125, 401(k), HSA, FSA, post-tax voluntary, garnishment, levy), and maps to Fusion Element classifications with correct Iterative Calculation, Balance feeds and Costing setup. Garnishments — child support, federal/state tax levies, bankruptcy, student loans, creditor garnishments — are mapped to Fusion Involuntary Deductions with full priority order, exemption rules and disposable-income calculations preserved. The full deduction and garnishment configuration is auto-generated as Fusion HCM Data Loader files.
Syntra ETL emits Fusion-native load formats for every Paycom data domain: HCM Data Loader (HDL) Worker.dat for employee master, assignments, contracts, contacts; HDL for Talent (performance, goals, succession); HDL for Absence Management and Time & Labor; FBDI Payroll Balance Initialization for pay-history balances; HDL Element-and-Element-Eligibility for deduction-code conversion; and REST API payloads for incremental delta loads during parallel-run. Every payload is validated against the current Oracle Fusion 26x release schema before submission, so validation errors surface locally — not in a 4-hour Fusion ESS job that fails on row 47,000 with an unhelpful 'invalid record' message.
Every employee and pay record extracted from Paycom is hashed at the source (employee hash + assignment hash + paycheck hashes + balance hashes). Every record loaded into Fusion is re-hashed post-load. The reconciliation engine compares counts (employees, paychecks, deductions, garnishments), sum totals (gross pay, net pay, FIT, FICA, Medicare, state tax per state, total deductions per code) and hash signatures per business unit per quarter. Any record that fails Fusion validation is captured with the exact field-level reason ready for bulk fix. Output is a signed timestamped reconciliation pack: Paycom payroll register vs Fusion payroll register to the penny, headcount vs headcount, W-2 totals vs YTD balances. Internal audit signs off on the pack directly.
Yes. After the initial bulk load, Syntra ETL captures Paycom deltas via the REST API's modified-since watermark on each domain (employee, assignment, paycheck, deduction, benefit enrollment, performance review) and replays them into Fusion through REST APIs. This supports the standard parallel-run pattern: Paycom continues processing payroll for 1–2 pay-cycle parallels while Fusion is validated to the penny. Gross-to-net reconciled per employee per pay period across both systems. Once HR, payroll ops, treasury and compliance sign off, the next pay period cuts to Fusion and the Paycom tenant moves to read-only archive mode. ACH origination and tax-deposit cutover are sequenced with the bank and IRS/state agencies during this window.
SOX requires 7-year retention of financial records — payroll GL entries trace back to paychecks, which trace back to time records, which trace back to original punches. FLSA (Fair Labor Standards Act) requires 3 years of payroll records and 2 years of supporting timekeeping detail. ACA Form 1095-C requires 3 years of retention plus coverage history. Syntra ETL's paycom data migration preserves the full chain: GL line in Fusion → Payroll Run → Paycheck → Employee Time Card → Punch, with every hop signed and timestamped. Whether the supporting detail lands in Fusion or in the long-term Paycom archive, the read-access log is captured for SOX, DOL and IRS audit evidence. No reconstruction needed when auditors arrive.
