Overview
Moving from greytHR to Recruit CRM is a cross-domain migration that requires explicit scope definition because the two platforms serve different functions. greytHR is a full-suite HRMS and payroll platform covering the Indian statutory stack, employee lifecycle management, and attendance processing for SMEs. Recruit CRM is a cloud-based ATS and recruitment CRM for staffing and agency recruiters that tracks candidates, clients, job orders, and placement pipelines. There is no direct equivalent in Recruit CRM for greytHR's employee records, payroll runs, statutory compliance fields, leave balances, or attendance data. We map the candidate, contact, and job data that can migrate cleanly, flag every greytHR module with no destination target, and deliver a structured handoff document so your team knows exactly what requires manual re-entry or a parallel system. Recruit CRM's unlimited free trial, per-user pricing starting at $85 per month, and 2-3 hour onboarding contrasts with greytHR's per-employee model and month-end statutory processing workflow, which shapes how companies time the cutover.

Object mapping
Each row shows how a greytHR object lands in Recruit CRM & ATS, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
greytHR
Employee
Recruit CRM & ATS
Candidate
1:1greytHR Employee records are the primary candidate source when migrating hiring data. We extract employee first name, last name, personal email, phone, current designation, department, date of joining, and resume or CV files where attached. The mapping discards statutory fields (UAN, PF, ESI, PAN, Aadhaar) because Recruit CRM has no equivalent fields for government compliance identifiers. Where greytHR stores former employees with an exit date, we map them as inactive Candidates with a status flag rather than active placements.
greytHR
Candidate records (greytHR ATS module)
Recruit CRM & ATS
Candidate
1:1If greytHR's ATS module was used, candidate records map directly to Recruit CRM Candidates using email as the dedupe key. Skills, work history, education, and source attribution migrate to Recruit CRM's corresponding Candidate fields. Candidate status from greytHR maps to Recruit CRM's pipeline stage values.
greytHR
Position History
Recruit CRM & ATS
Candidate Work History
1:1greytHR stores department, designation, grade, and location changes with effective dates as a position history timeline. We extract the most recent designation and department as the primary work history entry in Recruit CRM, preserving the full timeline as candidate notes for audit purposes. If Recruit CRM is configured with structured work history fields, we map the most recent two positions with dates and job title.
greytHR
Company
Recruit CRM & ATS
Client
1:1greytHR Company records (if the HRMS module tracks client or vendor companies alongside employees) map to Recruit CRM Client records. The company name, website, industry, and contact person details transfer. Note that greytHR does not typically store client companies unless used for agency billing; if no Company records exist in greytHR, this object is skipped.
greytHR
Job Opening (greytHR ATS)
Recruit CRM & ATS
Job
1:1greytHR job postings and requisitions map to Recruit CRM Jobs with job title, description, location, employment type, and salary range. Job status (open, filled, on hold) maps to Recruit CRM status flags. Active jobs migrate as open Jobs; filled jobs migrate as closed Jobs with placement references.
greytHR
Placement
Recruit CRM & ATS
Placement
1:1Hired candidate records from greytHR map to Recruit CRM Placements with candidate link, client link, job link, start date, and billing terms. Where greytHR stores placement fee and commission data, we map it to Recruit CRM's placement records. If greytHR does not have a placement object, this step is skipped and documented as a gap.
greytHR
Custom Fields
Recruit CRM & ATS
Custom Fields
lossygreytHR allows custom fields on employee and candidate records using a List of Values (LOV) system. We export both the custom field values and the LOV definitions, then map them to Recruit CRM custom fields of the matching type (text, picklist, number, date). LOV values are re-created as picklist options in Recruit CRM before data import.
greytHR
Employee Self Service portal data
Recruit CRM & ATS
Not applicable
1:1greytHR ESS portal data (mobile app access records, payslip download history, leave request logs) has no equivalent in Recruit CRM because Recruit CRM does not manage employee self-service or payslip distribution. We flag this as a gap in the handoff document. If the customer used greytHR ESS for candidate-facing onboarding communication, the data does not migrate.
greytHR
Payroll Runs
Recruit CRM & ATS
Not applicable
1:1Payslip data (gross, deductions, net pay) is exportable from greytHR but Recruit CRM has no payroll module. We export payroll run summaries as reference documents for the customer's finance team but do not map them to Recruit CRM records. Payroll reconfiguration must happen in the customer's chosen payroll platform separately.
greytHR
Statutory Compliance (PF/ESI/TDS)
Recruit CRM & ATS
Not applicable
1:1UAN, PF numbers, ESI numbers, PAN, and TDS section data are stored as structured fields on greytHR Employee records. Recruit CRM has no equivalent for government compliance identifiers. We export statutory fields as a standalone CSV reference file and flag them as high-priority for manual preservation in the customer's official PF/ESI portal downloads before the greytHR account is closed.
greytHR
Leave Management
Recruit CRM & ATS
Not applicable
1:1Leave entitlement, accrual, usage history, carry-forward balances, and encashment records do not map to Recruit CRM because Recruit CRM tracks candidate hiring status, not employee leave entitlements. We export current leave balances as a snapshot CSV. Carry-forward and encashment logic must be reconfigured in the customer's destination HRMS or payroll platform separately.
greytHR
Attendance Records
Recruit CRM & ATS
Not applicable
1:1greytHR stores swipe logs, shift schedules, overtime, and regularization data. Recruit CRM has no attendance tracking module. We export attendance records as CSV snapshots but do not map them to Recruit CRM records. Attendance reconfiguration requires a separate HRMS or time-tracking tool.

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.
greytHR gotchas
Statutory field data quality directly impacts government filings
Attendance regularization status does not always reflect true swipe data
Leave carry-forward and encashment rules are policy-specific, not record-specific
API lacks documented bulk export endpoint for historical payroll data
Recruit CRM & ATS gotchas
API rate limits are license-scaled and can throttle bulk migration
Custom field schemas vary per organization and require field-level mapping
Files and email attachments require separate extraction and re-upload
Email sequences and automation logic do not transfer between platforms
Pair-specific challenges
Migration approach
Discovery and ATS module confirmation
We confirm whether greytHR's ATS module is active and populated by running a direct API query against the candidate and job endpoints. If no candidate records exist, we scope the migration as an employee record extraction only and discuss whether a downstream HRMS migration would be more appropriate than a Recruit CRM migration. We also inventory custom fields, LOV definitions, active job postings, and placement records to establish the full candidate-facing scope. Statutory and payroll modules are documented as out-of-scope for Recruit CRM with an explicit gap list delivered to the customer.
Data-model gap analysis and handoff planning
We produce a written data-model gap analysis that lists every greytHR module, its Recruit CRM equivalent (or explicit lack thereof), and the recommended handling for each. Statutory fields, payroll runs, leave balances, and attendance records are flagged as requiring export-only handling and a separate destination system. This document is the primary deliverable that allows the customer's HR and finance teams to plan parallel migrations to a payroll platform if needed.
Deduplication and data cleanup
We extract all greytHR Employee and Candidate records, run an email-based deduplication pass to merge duplicates, standardize name formatting, and clean malformed contact data. Where picklist values from greytHR LOVs have no Recruit CRM equivalent, we create matching picklist options in Recruit CRM before import begins. This step adds 3-5 business days and must complete before any Recruit CRM imports run.
Recruit CRM configuration and sandbox import
We configure Recruit CRM custom fields, picklists, pipeline stages, and client records in the destination environment. If a Sandbox environment is available, we run a full import validation with production-like data volume before the production cutover. The customer's recruiting lead spot-checks 25-50 candidate records for field accuracy and signs off the schema and mapping before production migration begins.
Production migration in dependency order
We run production migration in record-dependency order: Clients (from greytHR Company records), Candidates (from greytHR Employee and Candidate records with dedupe applied), Jobs (from greytHR job postings), Placements (hired candidates with client and job links), and Custom Field values. Statutory, payroll, leave, and attendance data are exported as CSV snapshots on the same day and delivered to the customer with a portal download checklist for official government filings.
Cutover, validation, and handoff
We freeze greytHR writes during cutover and run a final delta export of any records modified during the migration window. Recruit CRM is enabled as the recruitment system of record. We deliver the data-model gap analysis, statutory export CSVs, and the official PF/ESI portal download checklist to the customer's admin team. We support a one-week hypercare window for reconciliation issues. We do not rebuild greytHR workflows, leave policies, or payroll configurations in Recruit CRM because those features do not exist in the destination platform; we deliver written recommendations for a parallel payroll platform migration if ongoing statutory filing is required.
