Overview
Moving from Apex Human Capital Management to BambooHR is a shift from a payroll-service-oriented HCM suite to an HR-first platform designed for small and mid-sized businesses. Apex stores payroll registers, accrual carryover rules, tax jurisdiction codes, and compensation history in client-configured tables that require transformation before they fit BambooHR's simpler data model. We extract the full employee core, benefits election snapshots, PTO balance snapshots, time entries, and payroll register history year-by-year to preserve audit trails. We flag every accrual policy rule and tax jurisdiction code that cannot auto-migrate so the customer's HR admin rebuilds those configurations with a written reference guide before go-live. Workflows, automations, and approval chains built in Apex do not migrate; we deliver an inventory document for BambooHR's admin to rebuild them post-migration.

Object mapping
Each row shows how a Apex Human Capital Management 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.
Apex Human Capital Management
Employee
BambooHR
Employee
1:1Core employee records (personal data, employment status, job title, department, hire date, termination date) export cleanly from Apex via the standard data dump. Apex stores the employee as a primary anchor record with an assigned employee ID; BambooHR auto-assigns its own Employee ID. We preserve the Apex employee ID in a custom field (apex_employee_id__c) so the migration maintains a reference anchor across all downstream object mappings. Employment status, pay type, exempt/non-exempt classification, and manager reporting line map directly to BambooHR standard fields.
Apex Human Capital Management
Org Structure
BambooHR
Department
1:1Apex stores department hierarchy as a flat list with parent references rather than a nested tree, which means the reporting structure does not export as a ready-to-import hierarchy. We reconstruct the department tree from the parent reference data during the transform phase and map it into BambooHR's department structure. Any department with no parent becomes a top-level division; children attach under their named parent. If the Apex employer uses cost center codes or location-specific department names, we preserve those as department aliases in BambooHR.
Apex Human Capital Management
Payroll Register
BambooHR
Payroll History
1:1Payroll run history with earnings, deductions, and tax withholdings exports year-by-year from Apex. We chunk large registers by payroll date range to avoid export timeouts and preserve the audit trail structure. Each payroll register row becomes a set of line items in BambooHR's payroll history module, with earnings classified under the matching earning code and deductions (benefits, garnishments, voluntary deductions) mapped to BambooHR deduction types. Historical gross, net, federal withholding, state withholding, and FICA amounts are preserved as separate entries.
Apex Human Capital Management
Compensation History
BambooHR
Pay Rate / Compensation
1:1Pay rate changes, bonuses, and commission records store effective dates and reason codes in Apex's proprietary compensation tables. We extract the full compensation history including base pay, pay frequency, pay type (salary, hourly, commission), bonus amounts, and effective dates. Rate changes migrate as a compensation history timeline within BambooHR's employee record. Commission and bonus amounts with non-standard earning codes are mapped to BambooHR custom earning codes created during schema setup.
Apex Human Capital Management
PTO Balance
BambooHR
Time Off
1:1Current PTO accrual balances export from Apex as a snapshot of available, used, and accrued amounts per leave type. Apex stores carryover rules, accrual caps, and earning-rate logic in client-configured tables that are not always included in a standard data export. We extract current balances as a snapshot and map them to BambooHR time-off balances. The accrual rate logic, carryover rules, and cap thresholds require manual reconfiguration in BambooHR; we flag every accrual policy found in the export with its rule parameters so the customer's HR admin rebuilds the policies in BambooHR before go-live.
Apex Human Capital Management
Tax Code
BambooHR
Tax Setup
lossyFederal, state, and local tax code assignments per employee export from Apex as lookup tables with jurisdiction-specific withholding codes. These codes do not map 1:1 to BambooHR's tax setup fields because tax jurisdiction identifiers vary by employer state registration. We extract the full jurisdiction taxonomy, create a mapping table of every jurisdiction code found, and present it to the customer for manual review and approval before applying it to BambooHR's tax setup per employee.
Apex Human Capital Management
Benefits Election
BambooHR
Benefits
1:1Health, dental, vision, and retirement plan elections export per employee with coverage start dates and carrier-specific plan IDs. We preserve the full election snapshot including dependent information and coverage tier (employee only, employee plus spouse, family). Carrier-specific plan IDs do not map 1:1 to BambooHR's benefits carrier list; we document the carrier name, plan name, and coverage tier as a reference table that the customer's HR admin uses to set up the equivalent benefit plans in BambooHR.
Apex Human Capital Management
Time Entry
BambooHR
Time Tracking
1:1Clock-in/out records and hours worked export per pay period from Apex. When BambooHR's time-tracking schema differs, we map hours to earning codes and flag any entries that fall outside a standard workweek structure. Entries from pay periods that cross midnight or use split shifts require particular attention to ensure hours map correctly. Overtime calculation rules and meal break deduction logic are documented separately as they require manual configuration in BambooHR's time-tracking policy setup.
Apex Human Capital Management
Document
BambooHR
Employee File
1:1Onboarding documents, offer letters, employee files, and I-9 forms stored in Apex export as binary blobs or linked URLs. We preserve filenames, associate each document with the correct employee record in BambooHR, and import the files as employee file attachments. Any document with a filename that does not clearly indicate its type is flagged for the customer's HR admin to rename or categorize in BambooHR. Documents that Apex stores as URLs to external storage rather than embedded files require the customer to confirm the source URL remains accessible or to upload the file directly into BambooHR.
Apex Human Capital Management
ACA Compliance Record
BambooHR
Employee (compliance fields)
1:11095-C forms and coverage measurement records export with employee associations intact from Apex. We map IRS form data to the applicable BambooHR employee compliance fields and flag any gaps in measurement period coverage that the customer needs to address before filing. BambooHR does not have a dedicated ACA compliance module; coverage measurement records are stored as notes or document attachments associated with the employee file, with a summary reference table provided in the migration deliverable.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Apex Human Capital Management gotchas
Accrual policy configurations are client-specific and not always exported
IRIS acquisition may affect API endpoint availability and roadmap
Tax jurisdiction data requires manual state-by-state mapping
Implementation timelines vary significantly by employer complexity
BambooHR gotchas
Undocumented API rate limits can trigger 503 errors
Per-employee pricing model requires active record count verification
API credentials must be sent on every request to avoid extra round trips
Custom field schema varies per account and requires manual inventory
Document and attachment exports are not covered by standard report exports
Pair-specific challenges
Migration approach
Discovery and data export assessment
We audit the Apex configuration across employee count, payroll history depth, custom fields, accrual policies, benefits plan types, state tax jurisdictions, and document storage volume. We assess which Apex API endpoints are available post-IRIS acquisition and identify any exports that require flat-file fallback. We count total fields to check against BambooHR's 400-field ceiling and identify which custom fields must be prioritized. The discovery output is a written migration scope with record counts per object, a list of accrual policy rules requiring rebuild, a state jurisdiction count, and a field prioritization list for any Apex custom fields that exceed the BambooHR export limit.
Schema design and earnings code taxonomy
We design the destination schema in BambooHR, mapping Apex employee fields to BambooHR standard fields and Apex custom fields to BambooHR custom fields where available. We create the department hierarchy, set up earning codes and deduction types for payroll history import, and configure benefit plan placeholders for the customer's HR admin to complete with carrier details. We document the accrual policy parameters extracted from Apex as a reference table and create a policy rebuild template. Tax jurisdiction mapping tables are prepared for the customer's manual review and approval before being applied to employee tax setup.
Sandbox migration and reconciliation
We run a full migration into a BambooHR sandbox environment using production-like data volume. The customer's HR lead reviews employee record accuracy across a random sample, verifies department hierarchy reconstruction, confirms payroll history totals match expected gross and net amounts, and validates time-off balance snapshots. Benefits election coverage tiers and dependent information are spot-checked. The HR team signs off the schema and mapping before production migration begins; any mapping corrections happen here, not in production.
Accrual policy documentation and admin rebuild guide
We extract every accrual policy rule from Apex (accrual rates, carryover limits, cap thresholds, anniversary date recalculation logic, negative balance allowance) and document it as a step-by-step rebuild guide for BambooHR's time-off policy configuration. This document is delivered before production cutover so the customer's HR admin has time to enter the policy rules into BambooHR before go-live. We do not configure BambooHR policies as part of the migration; the rebuild is an admin task using our documented reference.
Production migration in dependency order
We run production migration in record-dependency order: departments and org structure first, then employees with the Apex employee ID preserved in a custom field, followed by compensation history, benefits elections, PTO balance snapshots, time entries, and payroll register history chunked by year. Tax jurisdiction mapping from the approved table is applied per employee during the employee import phase. Documents import last, associated by employee record. Each phase emits a row-count reconciliation report and a field-level accuracy check against the Apex source before the next phase begins.
Cutover, delta migration, and handoff
We freeze write access in Apex during the cutover window, run a final delta migration for any records modified after the initial export, then enable BambooHR as the system of record. We deliver the accrual policy rebuild guide, tax jurisdiction mapping table, benefits election reference, and any remaining custom field data that could not be auto-migrated. We support a two-week hypercare window where we resolve reconciliation issues raised by the customer's HR team. We do not rebuild Apex workflows, automations, or approval chains in BambooHR; that work is documented separately for the customer's admin to configure using BambooHR's workflow builder.
