Overview
Paycom and BambooHR occupy different segments of the HRIS market. Paycom is a single-database HCM suite where employee data, payroll runs, timekeeping, PTO accruals, garnishment calculations and labor allocations are all stored together and tightly coupled. BambooHR is a cloud HRIS with a separate optional payroll add-on; its data model is flatter and does not include a native garnishment calculation engine. We extract the full Paycom employee record via their REST API, map the four-character eecode to a BambooHR employee ID, and transform payroll history into time-off records in BambooHR. Accrual balances transfer as as-of-date snapshots with the original accrual rule documented for your admin to re-enact in BambooHR. Active garnishment orders are extracted as deduction records and flagged for your payroll administrator to verify against BambooHR's deduction processing. Paycom workflows, approval chains and the Beti automated payroll build feature do not migrate; we deliver a written inventory of every active automation so your team can rebuild them in BambooHR.

Object mapping
Each row shows how a Paycom object lands in BambooHR, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Paycom
Employee
BambooHR
Employee
1:1Paycom employee records, keyed by four-character eecode, map to BambooHR employee records. We extract all standard fields (name, address, employment dates, compensation, employment status) plus any client-specific custom new hire fields exposed via get_new_hire_custom_fields. The Paycom eecode is preserved as a custom BambooHR field paycom_eecode__c for audit traceability and cross-reference during reconciliation. All employees extract in a single paginated API call and load via BambooHR's CSV import with custom field columns appended.
Paycom
Payroll Run
BambooHR
Time Off (as balance record)
1:manyPaycom payroll runs are effective-dated financial events (gross pay, net pay, tax withholdings, deduction amounts per period) that have no direct equivalent in BambooHR's HRIS schema. We transform each completed payroll run into a BambooHR Time Off entry capturing net pay and pay period. Federal and state withholding amounts, benefit deduction amounts, and garnishments are documented as separate ledger entries in the migration deliverable. The customer decides whether historical payroll data stays in a reporting-only spreadsheet post-migration or is archived in BambooHR as document attachments on the employee record.
Paycom
PTO Accrual Balance
BambooHR
Time Off Balance
1:1Paycom exposes current PTO balance as an as-of-date figure on the employee record but does not expose the full accrual rule configuration (accrual-per-pay-period, front-load, accrual-per-hour, carryover cap) via API. We extract the current balance snapshot per employee, the accrual policy name, and the effective date. We document the accrual rule for each policy group so your admin can configure matching BambooHR accrual policies. Two migration-path options are presented: re-enact accruals from hire date in BambooHR, or carry forward the Paycom balance as a starting point with a note on the record.
Paycom
Benefits Enrollment
BambooHR
Benefits Enrollment
1:1Paycom benefits elections (medical, dental, vision, 401k, HSA) store plan names, coverage tiers, deduction amounts and effective dates per employee per plan year. We extract all enrollment records and map them to BambooHR's benefits data structure. BambooHR does not include a native benefits administration module in all tiers; if the customer's BambooHR package includes benefits management, elections load as enrollment records. If not, we deliver a benefits enrollment summary CSV per employee and the customer coordinates benefits setup directly with their carrier.
Paycom
Garnishment and Deduction Order
BambooHR
Employee Deduction
1:1Paycom garnishment orders (child support, tax levies, wage assignments) carry deduction amounts computed internally based on federal and state guidelines. We extract the order record including begin date, end date, flat-versus-percentage flag, maximum allowable deduction and exemption amounts. We do not recalculate the deduction amount in our system. Each garnishment record is flagged in the migration output for your payroll administrator to verify against BambooHR's deduction processing before the first post-migration payroll runs. Garnishments with state-specific update schedules require manual reconfiguration in BambooHR's deduction setup.
Paycom
Timekeeping Record
BambooHR
Time Tracking (if BambooHR Time Tracking enabled)
1:1Paycom timecard data (clock-in/out timestamps, total hours, overtime flags, absence punches) is employee-owned with manager approval. If the customer's BambooHR subscription includes the Time Tracking module, we extract timecard summaries and load them as historical time entries. If BambooHR Time Tracking is not in scope, we deliver a timecard summary CSV per employee for manual reference or third-party time-tracking setup. Employee-owned timecard configuration in Paycom has no direct BambooHR equivalent; this workflow requires admin redesign.
Paycom
Labor Allocation Distribution
BambooHR
Cost Center or Custom Field
1:1Paycom labor allocation distributions split payroll costs across departments, jobs and GL codes via category codes, detail codes and GL codes from get_labor_allocation_distributions. These have no native equivalent in BambooHR's HRIS schema. We extract all active allocation rules and deliver them as a configuration inventory. Depending on the customer's accounting needs, labor allocations are either entered as BambooHR custom fields on the employee record, managed via a CSV lookup referenced in the customer's ERP integration, or documented for a BambooHR-administered cost center setup.
Paycom
Vault Payroll Card
BambooHR
Payment Method
1:1Vault is Paycom's proprietary payroll card. Employee enrollment status and card issuance records are stored in the Paycom employee record. We extract vault enrollment as a boolean flag and card delivery status. This maps to BambooHR's payment method setup where employees configure direct deposit or payment card. The Vault-specific card number and account routing are not transferable due to vendor lock-in; employees will need to re-enter payment method details in BambooHR.
Paycom
Background Check
BambooHR
Custom Field or Note
1:1Paycom Enhanced Background Checks store check status codes and completion timestamps per candidate. Results are extracted with status (pending, clear, flagged) and completion date. These map to BambooHR as a custom background check status field on the employee record or as a document attachment. The detailed criminal, credit or MVR results are not included in the Paycom API response; we document what was extracted so the customer can confirm compliance with their record-retention policy.
Paycom
Custom New Hire Field
BambooHR
Custom Employee Field
lossyPaycom custom fields on the new hire profile are client-specific and exposed via get_new_hire_custom_fields with field descriptions and values per eecode. Field types include text, select and date. We inventory all active custom fields during scoping, confirm their types, and pre-create matching custom fields in BambooHR before the employee import. Dropdown values from Paycom select fields must be manually re-entered as BambooHR dropdown options because there is no export of the picklist value set.

Migration approach
API access and data center confirmation
We begin every Paycom migration by confirming REST API access credentials and identifying the customer's data center cluster. Paycom operates four separate environments (DFW, OKC, PHX, Public), each with a distinct base URL. We retrieve the correct base URL from the customer's Paycom account representative during scoping. If API access has been restricted or is unavailable, we escalate to Paycom's data team for a direct file export, which can add five to ten business days. No extraction work begins until credentials and routing are confirmed.
Paycom data audit and scoping
We run a discovery extraction across all Paycom objects in scope: employee records (all fields and custom new hire fields), payroll runs, PTO accrual balances, benefits enrollments, active garnishment orders, labor allocation distributions, vault payroll card enrollment status, and background check status. We produce a record-count inventory and flag any data-quality issues (duplicate eecodes, missing required fields, orphaned records) before mapping begins. This audit output becomes the baseline for the migration reconciliation report.
Mapping design and accrual balance decision
We design the Paycom-to-BambooHR object mapping for all ten object types, including custom field type matching and any value transformation required. The PTO accrual balance decision is made explicitly at this stage: we present the customer with the option to re-enact accruals from hire date in BambooHR (cleaner accounting but requires historical data) or to carry forward the Paycom balance as a starting balance with a documented note. Both paths are documented. Custom new hire fields are pre-created in BambooHR as custom employee fields before the import.
Sandbox migration and reconciliation
We run a full migration into the customer's BambooHR sandbox environment before touching production data. The customer's HR lead reviews a record-by-record reconciliation of 25-50 employees against the Paycom source, confirms that garnishment records are flagged correctly, validates accrual balance entries, and signs off the mapping before we proceed to production. Any field mapping corrections, custom field additions or accrual-path decisions are finalized here. The sandbox run also confirms that BambooHR's import CSV format handles the customer's specific field types without silent truncation.
Production import in dependency order
We run the production migration in sequence: employees first (with all custom fields and the Paycom eecode preserved), then benefits enrollments, then garnishment orders with deduction flags, then PTO balance records, then payroll history time-off entries, then labor allocation configuration inventory, then vault payroll card enrollment flags. Each phase emits a row-count reconciliation report before the next begins. The customer runs at least one full payroll cycle in BambooHR before decommissioning Paycom.
Cutover, delta sync and workflow handoff
On migration day, we run a final delta extraction of any records modified in Paycom between the last full extract and the cutover window, then disable employee writes in Paycom. We deliver the Paycom workflow and automation inventory document, the garnishment verification checklist and the labor allocation configuration summary to the customer's HR admin. We remain available for a five-business-day post-cutover window to address reconciliation issues surfaced by the first BambooHR payroll run. We do not rebuild Paycom workflows as BambooHR automations within the migration scope; that work requires a separate scoping engagement.
