Overview
Moving from ZenHR to BambooHR is a regional pivot as much as a platform switch. ZenHR is built around MENA-specific labor law, social insurance, and tax compliance; BambooHR operates under a US and Western HRIS model with no built-in EOSB, GOSI, or GCC-specific payroll rules. We close that gap by preserving MENA financial fields (bank account details, social insurance numbers, end-of-service benefit amounts) in custom fields on the BambooHR Employee record, sequencing all Timeoff Transactions in date order to rebuild accrual balances, and migrating termination records with their original effective_date as a canonical field so that gratuity calculations can be verified in the destination. ZenATS Candidate records require a separate manual export because the candidate communication log bodies are not API-accessible. BambooHR's time-off management does not include clock-in/clock-out attendance tracking; we migrate aggregated attendance summaries as custom fields or notes rather than raw punch-event data. Workflows, approval chains, and automated payroll rules do not migrate; we deliver a written inventory for the customer's admin to rebuild in BambooHR's workflow builder.

Object mapping
Each row shows how a ZenHR 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.
ZenHR
Employee
BambooHR
Employee
1:1ZenHR Employees map to BambooHR Employees with the full Personal, Professional, and Financial sections mapped to BambooHR's employee record fields. ZenHR's bank account details, GOSI number, and salary components transfer to BambooHR's bank info section and custom fields. MENA-specific fields that have no BambooHR native equivalent (end-of-service benefit rate, notice period in days, visa status) are created as custom fields in BambooHR during the pre-migration schema phase. Every ZenHR tenant has unique custom fields on the Employee object; we audit these during discovery so that null values do not land on BambooHR mandatory fields during import.
ZenHR
Timeoff / Leave Request
BambooHR
Time Off
1:1ZenHR Timeoff records carry balance, request status, and a transaction history of accruals and deductions. BambooHR's Time Off tracks current balance per policy but does not expose a per-employee transaction audit trail by default. We sequence all ZenHR Timeoff Transactions in chronological date order, calculate the opening balance at the migration effective date, and set the BambooHR opening balance accordingly. Pending leave requests are flagged for the customer to re-submit post-migration because BambooHR requires an active employee and a valid workflow to create requests.
ZenHR
Documents
BambooHR
Employee Files
1:1ZenHR Documents (contracts, IDs, certificates, offer letters) with e-signature metadata migrate to BambooHR Employee Files attached to the corresponding Employee record. We transfer document type, expiry date, and upload timestamp as metadata fields. Binary file transfers are handled separately via BambooHR's file upload API. Any document that has expired is flagged in the migration report for the customer's admin to handle per BambooHR's expiry alert configuration.
ZenHR
Organizational Structure: Branch
BambooHR
Location
1:1ZenHR Branches (physical office locations across the MENA region) map to BambooHR Locations. Each Branch's address, country, and timezone transfer as Location fields. Branch-level settings that govern overtime rules or leave policy applicability are noted in the migration report and can be mapped to BambooHR Time Off policies per Location if the customer's configuration requires it.
ZenHR
Organizational Structure: Department / Level / Position
BambooHR
Department
1:manyZenHR separates Branches, Levels, and Positions as distinct structural objects with cross-references. BambooHR collapses organizational hierarchy into a single Departments list with a Name field. We map ZenHR Departments and Levels into BambooHR Departments, preserving Level information as a custom field on the Employee record (e.g., custom_employee_level__c) if the customer's reporting requires it. Positions that function as job titles map to the Employee job title field.
ZenHR
Termination and Final Settlement
BambooHR
Employee (Employment History)
lossyZenHR Terminations are separate records with EOSB/gratuity amounts and effective dates. We migrate each Termination as a historical Employee record with an Employment History entry in BambooHR, setting the termination date and preserving the EOSB amount, final settlement currency, and notice period served in custom fields. The original effective_date is preserved as the canonical termination date rather than the migration import timestamp. This is critical for MENA labor law compliance audits and for any future gratuity recalculation.
ZenHR
Loan
BambooHR
Employee (Custom Fields)
lossyZenHR Employee Loans with principal, remaining balance, and repayment schedule map to a custom loan object or custom fields on the BambooHR Employee record. BambooHR does not have a native Loans module. We create custom fields for loan_principal__c, loan_remaining_balance__c, loan_monthly_deduction__c, and loan_start_date__c, and flag active loans in the migration report for the customer's admin to verify and continue or close the repayment schedule in the destination system.
ZenHR
Overtime
BambooHR
Employee (Custom Fields) or Time Off
lossyZenHR Overtime records with type classification (regular, holiday, weekend), hours, and rate map to custom fields on the BambooHR Employee record. BambooHR's Time Off does not natively support overtime types. We aggregate overtime by type and employee for the migration period and store the total hours and average rate as custom fields. Customers who need ongoing overtime tracking use BambooHR's Time Tracking add-on or a third-party time-clock integration post-migration.
ZenHR
Work Shifts and Attendance Details
BambooHR
Employee (Custom Fields)
lossyZenHR Branch Employee Shifts assign employees to shift schedules by branch and date range. BambooHR does not have a native clock-in/clock-out module (Time Tracking is available as a separate add-on). We migrate shift assignments as custom fields on the Employee record and aggregate attendance summaries (total regular hours, total overtime hours per month) as summary custom fields. Individual clock-in/clock-out events are voluminous and not migrated unless the customer requires them specifically and has BambooHR Time Tracking enabled.
ZenHR
Users and Roles
BambooHR
Users
1:1ZenHR distinguishes Users (system login) from Employees (person records). A person can exist as an Employee without a User login. We map ZenHR User accounts to BambooHR user accounts by email match. Roles and permissions in ZenHR map to BambooHR's permission set model, where the admin assigns system access and module visibility per user. Any ZenHR User without an email match in BambooHR goes to a reconciliation queue for the customer's admin to provision.
ZenHR
Payroll / Financial Transactions
BambooHR
Payroll (BambooHR Payroll) or Employee (Custom Fields)
lossyZenHR payroll runs with line-item salary components, deductions, and net pay can be mapped to BambooHR Payroll if the customer is on BambooHR Payroll and operates in a US or Western payroll context. For MENA-based payroll, BambooHR Payroll does not support GCC tax withholding, GOSI deductions, or EOSB accrual calculations. We migrate payroll summary data (most recent salary, last pay date, last deduction amounts) as custom fields on the Employee record and recommend a parallel payroll system or manual reconciliation for historical payroll auditing. Off-cycle payments are noted in the migration report.
ZenHR
ZenATS Candidate
BambooHR
BambooHR Job Application
1:1ZenATS Candidates, Vacancies, and pipeline stage history migrate to BambooHR Job Applications and Job Openings. BambooHR Hiring does not have the same pipeline depth as ZenATS — there are no multiple rounds, interview scorecards, or custom stage templates by default. We migrate candidate name, email, phone, application date, vacancy name, and current stage. Candidate SMS and email communication bodies are not accessible via ZenHR API and are flagged as a data gap; we recommend a manual export from ZenATS for any candidate communication history the customer wishes to preserve.

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.
ZenHR gotchas
ZenATS candidates and SMS/email communication logs are not fully exportable via API
Custom fields are tenant-specific and require a pre-migration field audit
Attendance raw data volume can overwhelm bulk exports without pagination controls
Terminations require effective-date sequencing to preserve EOSB and leave balance calculations
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 tenant audit
We connect to the source ZenHR tenant via API and run a full field discovery covering all standard and custom employee fields, active Timeoff policies and transaction history, organizational structure (Branches, Levels, Positions), active and terminated employee counts, document types and volumes, loan records, overtime records, and attendance summary data. We also inventory any active workflow rules, approval chains, and ZenATS candidate data. The discovery output is a written migration scope document that enumerates every ZenHR object, its record count, its schema in the source tenant, and our proposed mapping to BambooHR equivalents. This document is the foundation for the field audit and the basis for the customer's sign-off before schema design begins.
BambooHR schema build and custom field creation
We configure the BambooHR destination tenant before any data migration. This includes creating all custom fields required to hold MENA-specific data (GOSI number, EOSB rate, notice period, gratuity basis, salary currency, loan fields, overtime fields, attendance summary fields). We configure Locations to match ZenHR Branches, Departments to map from ZenHR organizational levels, and Time Off policies that correspond to the customer's ZenHR leave policy by branch. We set up the initial Employee import template in BambooHR using the discovered field list. Schema build happens in a staging environment or parallel to the production tenant for review before go-live data is loaded.
User provisioning and Owner reconciliation
We extract every distinct ZenHR User referenced on Employee, Timeoff, Document, and Termination records and match by email against the BambooHR destination tenant's user list. ZenHR Users without a matching BambooHR user go to a reconciliation queue for the customer's admin to provision. This step is mandatory because BambooHR Employee records require an owning User for the system to function correctly. We also identify any ZenHR Users who are Employees without system login access (contractors, ex-employees) and handle them as terminated or inactive records based on the customer's instruction.
Sandbox migration and reconciliation
We run a full migration into the BambooHR production tenant using the discovered field map and the schema built in Step 2. We migrate in dependency order: Locations and Departments first (structural objects), then Employees with custom fields, then Time Off balances with opening balances set from the transaction history, then Documents, then Work Shifts and Attendance summaries, then Terminations with EOSB details, then Loans and Overtimes as custom field data. After each phase we emit a row-count reconciliation report comparing ZenHR source counts to BambooHR destination counts. The customer's HR lead spot-checks 25-50 random records for field-level accuracy and signs off before production cutover.
Production migration and cutover
We freeze write access to ZenHR during the production migration window, run a delta migration to capture any records modified between the sandbox run and production cutover, then enable BambooHR as the system of record. The production migration runs the same dependency order as the sandbox. Any records rejected during import (due to format errors, missing required fields, or duplicate detection) are logged in an error report for the customer's admin to resolve. We do not modify source data to fix errors — we flag, log, and let the admin correct in BambooHR directly.
Workflow rebuild handoff and post-migration support
We deliver a written inventory of every active ZenHR workflow, approval chain, and leave policy rule that does not have a BambooHR native equivalent. This document describes each ZenHR automation's trigger, conditions, and actions, and provides a recommended rebuild approach in BambooHR's workflow builder. We do not rebuild workflows as part of the migration scope. We support a five-business-day post-migration window where we resolve data integrity issues raised by the customer's HR team (record count discrepancies, missing fields, import errors). ZenATS candidate communication logs are handed off as a separate manual export task with instructions.
