Overview
Moving from Zimyo to BambooHR is a platform consolidation that narrows your HR stack to a US-market-focused HRIS with strong employee records management, built-in ATS, and optional payroll. Zimyo's all-in-one model covers payroll, attendance, performance, and engagement in one platform; BambooHR separates these into modular paid add-ons. We handle the object-level migration across employee profiles, leave balances, attendance logs, performance review data, and talent acquisition pipelines. Custom fields, effective-dated compensation records, and statutory compliance fields require mapping review during scoping. Workflows, approval chains, and Zimyo's engagement survey tools do not migrate as code; we deliver a written inventory for your admin to rebuild in BambooHR's HRIS structure. BambooHR's native payroll is US-only, so INR-denominated or multi-country payroll configurations from Zimyo require alternative payroll setup post-migration.

Object mapping
Each row shows how a Zimyo 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.
Zimyo
Employees
BambooHR
Employees
1:1Zimyo employee records map directly to BambooHR employee profiles. We map standard fields including name, date of birth, hire date, employment status, job title, department, location, compensation, bank details, and emergency contacts. Custom employee properties on the Zimyo side map to BambooHR custom fields, with type conversion (text to text, date to date, picklist to dropdown). Zimyo's employment type distinctions (full-time, part-time, contract) map to BambooHR's employee type field.
Zimyo
Leave Management
BambooHR
Time Off
1:1Zimyo leave types, entitlement balances, accrual rules, and carry-forward policies map to BambooHR Time Off policies. We validate each employee's leave balance independently against Zimyo reports before committing. Carry-forward rules require manual review in BambooHR post-migration because BambooHR handles carry-forward configuration per policy rather than per employee. Leave approvals and comments migrate as note attachments on the Time Off request record.
Zimyo
Attendance Records
BambooHR
Time Tracking (add-on)
lossyZimyo clock-in/clock-out timestamps with geo-location and overtime calculations do not map directly to BambooHR because BambooHR's Time Tracking add-on handles timesheets and billable hours rather than raw clock events. We map the most recent attendance summary (last 90 days) as a Time Off balance adjustment for employees transitioning to BambooHR's accrual-based time-off model. Historical attendance logs beyond 90 days are exported as a CSV file inventory for the customer's admin to reference. Overtime calculations from Zimyo do not migrate; overtime eligibility rules require rebuild in BambooHR's Time Tracking configuration.
Zimyo
Payroll Runs
BambooHR
BambooHR Payroll (add-on)
lossyZimyo payroll data (earnings, deductions, tax withholdings, net pay) maps to BambooHR Payroll if the customer activates that add-on. If BambooHR Payroll is not in scope, we export payroll history as a structured CSV inventory for the customer's finance team and payroll admin. INR-denominated payroll components require currency conversion with timestamped exchange rates before import into BambooHR's USD-only payroll module. Historical payroll runs cannot be retroactively loaded into BambooHR Payroll; only current and future payroll runs process natively.
Zimyo
Performance Reviews
BambooHR
Performance (Pro plan)
1:1Zimyo performance cycles, goals, competency ratings, self-assessments, and manager feedback map to BambooHR Performance when the customer licenses the Pro plan or above. Review templates and competency frameworks vary by organization and require schema alignment during scoping. Rating scales differ between platforms; we map Zimyo's rating values to BambooHR's 5-point scale with a custom field preserving the original Zimyo rating for audit. Goals and OKRs from Zimyo do not map to a native BambooHR object; we export them as a goals inventory CSV for manual re-entry or third-party goal-tracking tool integration.
Zimyo
Talent Acquisition
BambooHR
BambooHR ATS (included in Core)
1:1Zimyo job postings, candidate profiles, application stages, interview schedules, scorecards, and offer letters map to BambooHR's applicant tracking system. Hiring pipeline stages are configurable per organization; we map Zimyo stages to BambooHR pipeline stages during scoping. Candidate application history and status migrate with timestamps. We do not migrate Zimyo's job board posting configurations; the customer re-posts openings in BambooHR ATS post-migration.
Zimyo
Organization Structure
BambooHR
Departments
1:1Zimyo departments, cost centers, and locations map to BambooHR Departments and Locations. Reporting hierarchies migrate as supervisor relationships on employee records. Organization-level workforce management settings from Zimyo do not have a direct BambooHR equivalent; we export them as a configuration inventory for the customer's admin to reapply manually.
Zimyo
Documents
BambooHR
Employee Documents
1:1Employee documents (contracts, ID proofs, certifications, offer letters) migrate as BambooHR employee files with original filenames and upload timestamps preserved. File integrity checksums are generated post-upload to verify no corruption. Document categories from Zimyo map to BambooHR's document folder structure. Documents exceeding BambooHR's file size limits are flagged and exported to a shared cloud location with links in the employee record.
Zimyo
Custom Fields
BambooHR
Custom Fields
1:1Organization-specific custom fields from Zimyo migrate to BambooHR custom fields. We conduct type mapping during scoping: Zimyo text fields map to BambooHR Text fields, date fields to Date fields, and picklist fields to Dropdown fields. Multi-select picklists map to BambooHR's multi-select if the customer's plan supports them. Custom fields with no equivalent BambooHR field type are exported to a custom fields inventory CSV for manual placement or third-party tool integration.
Zimyo
Benefits Enrollments
BambooHR
Benefits (add-on)
1:1Benefit plans, enrollment elections, dependents, and coverage periods from Zimyo map to BambooHR Benefits if the customer licenses that add-on. Benefit types and plan names vary by organization and require value mapping. Historical enrollment records are effective-dated and migrate with the employee's start date as the coverage start. We do not migrate benefits administration rules or deduction calculations; those are configured fresh in BambooHR Benefits.
Zimyo
Expense Claims
BambooHR
Not natively supported
1:1Zimyo expense submissions, line items, category mappings, approval workflows, and reimbursement statuses do not map to a native BambooHR object. We export expense claim history as a structured CSV inventory for the customer's finance team. If BambooHR's Expenses functionality is activated via an add-on or third-party integration, the customer re-enters open claims post-migration. Approved and reimbursed claim history is preserved in CSV for audit purposes.
Zimyo
Time Entries
BambooHR
Time Tracking (add-on)
1:1Timesheets, billable hours, and project-time allocations from Zimyo map to BambooHR Time Tracking when that add-on is licensed. Custom timesheet fields and approval statuses require configuration review. We validate total hours against payroll runs where applicable and flag discrepancies before import. Project-time allocations do not have a native BambooHR equivalent; we export them as a time allocation inventory CSV.

Pair-specific challenges
Migration approach
Discovery and add-on selection
We audit the source Zimyo instance for employee record count, leave balances, attendance history depth, payroll run history, performance review data, talent acquisition pipeline volume, custom field schemas, and document inventory. We pair this with a BambooHR plan assessment: Core ($10/employee/month) covers employee records, ATS, and time-off; Pro ($17/employee/month) adds performance management; payroll and time-tracking add-ons are priced separately. The discovery output is a written migration scope and a BambooHR add-on recommendation based on which Zimyo modules are in active use.
API schema discovery and data export coordination
Because Zimyo does not publish API documentation, we conduct active schema discovery: we test endpoint responses, identify available objects and fields, and document the authentication method. If bulk export is accessible through Zimyo support, we coordinate a full data export in CSV or JSON format covering all in-scope objects. If bulk export is not available, we extract data through the admin interface in batches and normalize it to a standard schema before mapping begins. This step determines whether the timeline stays in the three-to-five-week range or extends to six to ten weeks.
BambooHR schema setup and custom field provisioning
We provision the destination BambooHR account with the required add-ons (Payroll, Time Tracking, Benefits, Performance) based on the scoping output. Custom fields from Zimyo are pre-created in BambooHR with matching types. Time Off policies are configured to approximate Zimyo's leave types. ATS pipeline stages are mapped from Zimyo's hiring stages. All configuration is validated in BambooHR's sandbox or test environment before production migration begins.
Sandbox migration and reconciliation
We run a full migration into the customer's BambooHR test environment using production-like data volume. The customer's HR lead reconciles record counts, spot-checks 20-30 random employee records against the Zimyo source, and validates leave balances. Any mapping corrections, custom field type mismatches, or policy configuration issues surface here and are resolved before production migration. This step prevents data quality issues from reaching the live BambooHR instance.
Production migration in dependency order
We run production migration in dependency order: employee records first (with custom fields resolved), followed by time-off balances and policies, ATS candidate and application history, performance review data, documents, benefits enrollments (if applicable), and attendance summary (last 90 days). Payroll history is exported as CSV inventory rather than loaded into BambooHR Payroll. Each phase emits a row-count reconciliation report before the next phase begins. Any records that fail import are held in a retry queue and resolved within 48 hours.
Cutover, validation, and handoff
We freeze Zimyo write access during cutover, run a final delta migration of any records modified during the migration window, then enable BambooHR as the system of record. We deliver the following handoff documents: Workflow and approval chain inventory (requiring manual rebuild in BambooHR), leave carry-forward configuration worksheet, payroll history CSV inventory, goals and OKRs CSV inventory, and attendance history CSV inventory. We support a five-business-day hypercare window where we resolve reconciliation issues. We do not rebuild Zimyo workflows, approval chains, or engagement surveys in BambooHR; those require admin-level rebuild post-migration.
