Overview

What this migration involves

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.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

Zimyo logo

Zimyo

What's pushing teams away

  • Occasional software glitches causing screen freezing and processing errors in leave and payroll workflows disrupt HR operations and erode confidence in data accuracy.
  • Performance issues during busy periods make navigation and report generation feel sluggish, frustrating HR staff who need quick access to data during critical payroll windows.
  • Missing features force manual workarounds and data feeding, with some reviewers noting server unavailability and notification gaps complicating their workflows.
  • Limited integration capabilities compared to larger HRMS platforms restrict connectivity with specialized third-party tools and custom business workflows.
  • Despite an intuitive interface, the learning curve for new users remains steep when navigating all available features and configuration options.

Choosing

BambooHR

What's pulling them in

  • Lowest friction entry point for SMBs moving off spreadsheets — intuitive interface means most teams are functional within days, not weeks.
  • Consolidation value: BambooHR merges ATS, onboarding, HR records, time-off, and payroll into a single pane of glass that employees never need to leave.
  • Volume discounts applied automatically by headcount, so pricing scales predictably as the company grows without renewal negotiations.
  • BambooHR reports most customers go live in four to six weeks, making it a realistic commitment for under-resourced HR teams.
  • Award-winning Support Heroes cited frequently in reviews — responsive human support after implementation is a differentiator.

Object mapping

How Zimyo objects map to BambooHR

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

maps to

BambooHR

Employees

1:1
Fully supported

Zimyo 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

maps to

BambooHR

Time Off

1:1
Fully supported

Zimyo 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

maps to

BambooHR

Time Tracking (add-on)

lossy
Fully supported

Zimyo 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

maps to

BambooHR

BambooHR Payroll (add-on)

lossy
Mapping required

Zimyo 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

maps to

BambooHR

Performance (Pro plan)

1:1
Mapping required

Zimyo 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

maps to

BambooHR

BambooHR ATS (included in Core)

1:1
Fully supported

Zimyo 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

maps to

BambooHR

Departments

1:1
Fully supported

Zimyo 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

maps to

BambooHR

Employee Documents

1:1
Fully supported

Employee 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

maps to

BambooHR

Custom Fields

1:1
Mapping required

Organization-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

maps to

BambooHR

Benefits (add-on)

1:1
Mapping required

Benefit 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

maps to

BambooHR

Not natively supported

1:1
Mapping required

Zimyo 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

maps to

BambooHR

Time Tracking (add-on)

1:1
Mapping required

Timesheets, 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

  • BambooHR Payroll is US-only and handles no INR or multi-country payroll

    BambooHR Payroll is designed exclusively for US payroll processing with US tax compliance. Organizations migrating from Zimyo that use INR-denominated payroll, APAC statutory compliance, or multi-country payroll will not be able to run payroll in BambooHR natively. We flag this during scoping and export payroll history as a structured CSV inventory. The customer selects an alternative payroll platform (Gusto, Rippling, ADP, or Paychex) post-migration. BambooHR's payroll add-on should not be activated if the organization operates outside the US.

  • Zimyo's undocumented API requires schema discovery during scoping

    Zimyo does not publish a public API documentation portal, rate limit specifications, or bulk export endpoint schema. API authentication, endpoint structure, and request pacing are not publicly documented. We conduct schema discovery during the scoping call, coordinate with Zimyo support for bulk export access where available, and use standard REST API patterns with conservative request pacing. If bulk export is not accessible, we request data exports through Zimyo's admin interface and process them as CSV batches, which extends the timeline by one to two weeks.

  • BambooHR Time Tracking add-on does not replace Zimyo's attendance clock

    Zimyo's native attendance module captures clock-in/clock-out timestamps with geo-location, shift mappings, and overtime calculations. BambooHR's Time Tracking add-on handles timesheet-based time entry and billable hours, not raw clock events. We migrate the last 90 days of attendance as a time-off balance adjustment and export the full attendance history as a CSV inventory. Overtime eligibility rules, shift schedules, and geo-location tracking do not migrate; these require rebuild in BambooHR's Time Tracking configuration or a third-party attendance tool.

  • Leave carry-forward rules are per-policy in BambooHR, not per-employee

    Zimyo allows per-employee leave carry-forward configurations including custom carry-forward limits, expiry dates, and encashment rules. BambooHR handles carry-forward at the Time Off policy level. We map each employee's carry-forward balance as an adjustment to their starting accrual in BambooHR's corresponding policy, but the ongoing carry-forward rules must be reconfigured manually per policy post-migration. We deliver a carry-forward configuration worksheet mapping each Zimyo employee rule to a BambooHR policy setting.

  • Custom field type mapping requires manual review for complex field structures

    Zimyo custom fields support organization-specific types that may not map directly to BambooHR's supported field types. Multi-checkbox fields, formula fields, and conditional visibility rules require manual review during scoping. We map every custom field to a BambooHR equivalent type and flag any unmappable fields in a custom field inventory. Fields that cannot map natively are exported to a CSV inventory for manual re-entry or third-party integration.

Migration approach

Six steps for a successful Zimyo to BambooHR data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

BambooHR

Destination

Strengths

  • Single platform consolidating ATS, onboarding, HR records, payroll, and time-off reduces system sprawl for SMBs.
  • Fast implementation — BambooHR reports four to six weeks from kickoff to go-live for most customers.
  • Per-employee pricing with automatic volume discounts makes cost predictable as headcount grows.
  • Strong customer support reputation (Support Heroes) cited consistently across G2, Capterra, and direct testimonials.
  • Well-documented API with UTF-8 encoding, clear field types, and HTTPS-only access.

Weaknesses

  • Mobile application is significantly limited compared to the desktop experience, frustrating remote and field workers.
  • Companies above 150–200 employees frequently outgrow the platform's feature depth and customization surface.
  • Limited advanced reporting and analytics compared to enterprise HR platforms — custom report building is the ceiling.
  • PTO and profile customization are pain points — non-standard accrual policies and complex org structures require workarounds.
  • Document management and attachment handling lack the granularity of dedicated document-centric HR systems.

Most migrations land between three and five weeks for accounts under 200 employees with standard employee records, leave balances, and ATS data. Migrations that include payroll history, performance review data, attendance records, or extensive custom fields extend to six to ten weeks. The primary timeline variable is whether Zimyo bulk export access is available; if data must be extracted through the admin interface in batches, add one to two weeks for schema discovery and export coordination.
