Overview

What this migration involves

greytHR and Crelate serve different stages of the employment lifecycle. greytHR is a full HRMS and payroll platform built for Indian SMEs, covering the employee lifecycle from offer letter through statutory-compliant payroll runs, leave management, attendance tracking, and government filings. Crelate is a recruiting ATS and CRM designed for staffing agencies and in-house recruiting teams to manage candidates, job orders, placements, and client relationships through a drag-and-drop pipeline. The two platforms have minimal structural overlap. We do not migrate payroll runs, statutory compliance data (UAN, PF, ESI, TDS), or leave balances because Crelate has no equivalent payroll or HR administration module. We can extract employee contact information, emergency contact details, and skill/qualification data from greytHR and load those as candidate records in Crelate for re-hire pipelines or alumni sourcing. We flag every non-transferable greytHR object in the scoping report and deliver a written inventory of statutory documents and payroll records for manual filing continuity at cutover.

Why teams make this switch

Two sides of the same decision

Leaving

greytHR logo

greytHR

What's pushing teams away

  • Performance degradation at scale — multiple reviewers on G2 and Capterra report slow page loads and frequent manual refreshes required to complete routine operations.
  • Mid-to-large companies outgrow the platform when they need advanced workforce analytics, multi-country payroll, or deep integration with ERP systems that greytHR does not natively support.
  • Attendance sync reliability issues surface in reviews: swipe data occasionally fails to register, requiring manual regularization steps that erode trust in the system.
  • Switching mid-year creates anxiety around statutory filings (PF, ESI) — companies worry that migrating in the middle of a compliance cycle will cause government-filing errors or penalties.

Choosing

Crelate

What's pulling them in

  • Affordable per-seat pricing with transparent tiers makes Crelate accessible for small-to-mid staffing firms evaluating ATS platforms for the first time.
  • Fast implementation reported by customers—some describe getting live in a matter of minutes with support team assistance.
  • Unified ATS + CRM in a single product eliminates the need to buy and synchronize separate recruiting and sales tools.
  • Flexible custom fields across Contacts, Companies, and Opportunities allow recruiting teams to capture firm-specific data without developer involvement.
  • Positive reviews highlight the product's intuitive interface and functional breadth for teams that need recruiting workflows without enterprise overhead.

Object mapping

How greytHR objects map to Crelate

Each row shows how a greytHR object lands in Crelate, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

greytHR

Employee

maps to

Crelate

Person (Candidate)

1:many
Fully supported

greytHR Employee records contain demographic data (name, date of birth, gender, mobile, email, address) and employment data (department, designation, grade, joining date, employment status) that maps to Crelate Person records. We extract contact fields, emergency contact details, education and skill fields from greytHR, and load them as Crelate Person records. Active employees in greytHR map to Crelate Persons with a status tag (current-employee or re-hire-candidate). Former employees map to Persons tagged as alumni for re-hire pipelines. The greytHR statutory fields (UAN, PF, ESI, PAN, Aadhaar) do not migrate because Crelate has no equivalent statutory compliance module; we document these as a separate statutory handoff package.

greytHR

Employee: Department and Designation

maps to

Crelate

Person: Tags and Custom Fields

lossy
Fully supported

greytHR department, designation, and grade fields store the employee's current organizational position. We extract these values and map them to Crelate custom Person fields (department__c, designation__c, grade__c) or as tags on the Person record. The customer chooses field versus tag strategy during scoping based on how they plan to filter and report on candidate origin in Crelate.

greytHR

Employee: Skills and Qualifications

maps to

Crelate

Person: Skills and Tags

1:1
Fully supported

greytHR stores skills, certifications, educational qualifications, and prior experience on the Employee record. We extract these as comma-separated or multi-value fields and load them into Crelate Person skills fields and tags. Skill normalization may be required if greytHR uses free-text skill entries rather than a controlled vocabulary; we flag inconsistent skill formats during scoping.

greytHR

Employee: Emergency Contact

maps to

Crelate

Person: Custom Fields

1:1
Fully supported

greytHR emergency contact fields (name, relationship, mobile number) store as structured fields on the Employee record. We extract these and load them into Crelate custom Person fields (emergency_contact_name__c, emergency_contact_phone__c, emergency_contact_relationship__c). These fields are relevant if the customer plans to use Crelate for contractor or re-hire onboarding handoff.

greytHR

Payroll Runs

maps to

Crelate

None

1:1
Mapping required

greytHR payroll runs (gross pay, deductions, net pay, pay period, pay date) do not migrate to Crelate. Crelate has no payroll module and no field equivalent for compensation data. We export a payroll summary CSV from greytHR as a manual reference document for the customer's finance team. Statutory deductions (PF, ESI, TDS) are flagged as high-priority manual handoff items because government filings may reference mid-year payroll records.

greytHR

Leave Management

maps to

Crelate

None

1:1
Fully supported

greytHR leave balances, accrual history, carry-forward rules, and encashment records do not migrate to Crelate. Crelate has no leave management module. We export the current leave balance snapshot per employee as a CSV reference. Leave carry-forward rules defined in greytHR leave policies must be manually reconfigured if the destination platform includes leave management; we document the current policy settings during scoping.

greytHR

Attendance Records

maps to

Crelate

None

1:1
Fully supported

greytHR swipe logs, shift schedules, overtime data, and regularization status do not migrate to Crelate. Crelate has no attendance tracking module. We flag that greytHR community posts document occasional swipe visibility issues in the admin view where raw swipe data exists but regularization status has not been updated; we export both raw swipe logs and regularization status and flag contradictions for the customer's attention before migration.

greytHR

Statutory Compliance (PF/ESI/TDS)

maps to

Crelate

None

1:1
Fully supported

greytHR statutory fields (UAN, PF number, ESI number, PAN, Aadhaar, TDS section) do not migrate to Crelate. These fields are mandated for Indian government filings (EPFO, ESIC, TDS returns) and have no equivalent in Crelate's recruiting data model. We flag every statutory field as a mandatory cutover checklist item: the customer must download official PF/ESI challan history and TDS filing records from greytHR before cutover, as these records are required for mid-year government filing continuity. This is a high-severity handoff item.

greytHR

Claims and Expense Records

maps to

Crelate

None

1:1
Mapping required

greytHR expense claims, reimbursement amounts, and approval status do not migrate to Crelate. Crelate has no expense management module. If the customer uses Crelate for contractor placements and needs expense reimbursement tracking, they must configure a separate expense management workflow in Crelate or retain another tool. We export claim records as a CSV for the customer's finance team.

greytHR

Position History

maps to

Crelate

Person: Work History Custom Fields or Tags

1:1
Mapping required

greytHR stores department, designation, grade, and location changes with effective dates as a position history timeline. We extract the current position snapshot and map it to Crelate Person fields. If the customer wants historical position changes preserved, we load them as a custom text field or as work history entries on the Person record; Crelate's primary model does not support full position history timelines, so we compress to current position plus most recent prior role.

greytHR

Performance Reviews

maps to

Crelate

None

1:1
Mapping required

greytHR performance review cycles, ratings, goals, and feedback text do not migrate to Crelate. Crelate is a recruiting ATS and does not include performance management or review cycle tracking. We export completed review records as a CSV reference for the customer's HR team. In-progress review cycles at migration time are flagged as a cutover risk: the customer's greytHR admin must finalize or document any open review cycles before we freeze writes on the source system.

greytHR

Documents

maps to

Crelate

Person: Attachments

1:1
Mapping required

greytHR stores employee documents (offer letters, ID proofs, contracts, joining letters, previous employer documents) in its document module. We export document metadata (filename, type, upload date, employee linkage) and binary files where API access is granted. These files attach to the corresponding Crelate Person record as ContentDocumentLink attachments. The customer must verify that document access permissions in greytHR allow bulk export before migration. Some document types (PF forms, ESI cards, TDS certificates) should be retained separately as statutory handoff items.

Pair-specific challenges

  • greytHR statutory data has no destination equivalent

    greytHR stores UAN, PF numbers, ESI numbers, PAN, Aadhaar, and TDS section data as structured fields mandated for Indian government filings. Crelate has no statutory compliance module and no fields equivalent to these identifiers. We flag every statutory field as a mandatory cutover checklist item and recommend that the customer download official PF/ESI challan history and TDS filing records from greytHR before we freeze writes. Mid-year government filing continuity requires these records; losing access to them before a compliance cycle closes creates filing gaps that the customer's finance or compliance team must resolve directly.

  • greytHR payroll runs and statutory deductions do not migrate

    Crelate is a recruiting ATS that tracks placement fees, not employee compensation. greytHR payroll runs (gross, deductions, net pay, PF contribution, ESI contribution, TDS deduction) have no equivalent in Crelate's data model. We export payroll summary CSVs and statutory deduction registers as manual reference documents, but these do not load into Crelate. If the customer plans to use Crelate for contractor or gig worker payments, they must configure a separate payment or invoicing workflow post-migration; this is not in scope.

  • Leave balances and carry-forward rules require manual re-entry

    greytHR leave balances, accrual rates, carry-forward rules, and encashment records are policy-based, not record-based. Crelate has no leave management module. We export current leave balance snapshots as a CSV, but the customer must manually reconfigure leave policies in any replacement leave management tool. greytHR community posts document that leave carry-forward rules are often configured at the policy level rather than the individual record level, so the export captures balances at a point in time without the underlying computation logic.

  • Attendance regularization status may not reflect raw swipe data

    Multiple greytHR reviewers on G2 report that the admin view occasionally fails to display employee swipes even when the device registered the punch, causing the system to flag the record as requiring regularization. We export both the raw swipe log and the regularization status and flag records where the two contradict. If attendance data is migrated as-is without this check, false absence flags could propagate to payroll or compliance records at the destination.

  • Crelate field mapping requires manual configuration of custom fields before import

    Crelate's field mapping is administered through Settings > Core Records > Customize Fields, where administrators create custom fields before any import can map to them. greytHR custom fields on Employee records require pre-creation of matching Crelate Person custom fields. We handle field creation during schema design, but the customer must validate that the field types (text, picklist, date, number) match the greytHR data formats before migration begins. A mismatch between greytHR free-text dates and Crelate date fields, for example, causes import failures that require manual correction.

Migration approach

Six steps for a successful greytHR to Crelate data migration

  1. Discovery and migration boundary definition

    We audit the greytHR portal across all modules: employee count, active versus inactive employees, custom fields on the Employee object, leave balances at cutoff, payroll run history, statutory field population rates, document module access permissions, and any open performance review cycles. We identify what data maps to Crelate Person records and what data has no destination equivalent. We deliver a written migration boundary document: the greytHR objects that transfer to Crelate, the objects that export as CSV reference documents, and the statutory objects that require manual handoff before cutover. The customer reviews and signs off on the boundary before any extraction begins.

  2. Crelate custom field creation and tagging strategy

    We work with the customer to define the Crelate Person record schema that will receive greytHR data. This includes creating custom fields for department, designation, grade, emergency contact details, and any greytHR custom employee fields. We define a tagging taxonomy for Crelate (current-employee, alumni, re-hire-candidate) that the customer uses to classify migrated records. Crelate's field mapping is configured in Settings > Core Records > Customize Fields before extraction begins. We validate that greytHR data types (date formats, free-text versus picklist, numeric formats) are compatible with the Crelate field types we create.

  3. Data extraction and quality audit

    We extract greytHR employee records via the API with throttled sequential reads (greytHR does not document bulk export endpoints or rate limits, so we implement resume-from-cursor logic to handle large employee bases). We run a data quality audit against the greytHR statutory field schema and surface missing or malformed UAN, PAN, Aadhaar, and ESI values before extraction. We export attendance raw logs alongside regularization status and flag discrepancies. We export leave balance snapshots, payroll summary data, and document metadata with binary files where access is granted. The audit report is delivered to the customer for review before transformation begins.

  4. Transformation and Crelate import preparation

    We transform greytHR employee records into Crelate Person import format. Contact fields, emergency contacts, skills, department, designation, and grade map to the corresponding Crelate Person fields or tags. Statutory fields (UAN, PF, ESI, PAN) are stripped from the Person import but documented in the statutory handoff package. We compress position history to current role and most recent prior role. We validate record counts and run a sample import (25-50 records) into the customer's Crelate staging environment to confirm field mapping accuracy before the full load.

  5. Staging migration and reconciliation

    We run the full migration into the customer's Crelate staging environment. The customer reconciles record counts (Persons created, records with tags applied, records with attachments), spot-checks 25-50 random Person records against the greytHR source data, and validates that emergency contacts, skills, and department/designation fields populated correctly. Any field mapping corrections happen in staging. We do not proceed to production until the customer signs off on the staging reconciliation report.

  6. Production migration, statutory handoff, and cutover

    We run the production migration in a single cutover window after the customer freezes writes in greytHR. We deliver the statutory handoff package (PF/ESI challan history, TDS filing records, payroll summary CSV, leave balance snapshot) as a separate document set for the customer's finance and compliance teams. We deliver a written inventory of greytHR documents (offer letters, contracts, ID proofs) that were migrated as Crelate attachments. We do not migrate active payroll runs, leave policies, attendance workflows, or performance review cycles; these are documented separately for manual continuity or rebuild in the customer's chosen replacement tools. We support a one-week post-cutover window for reconciliation of any import errors.

Most migrations land between two and three weeks for organizations under 5,000 employee records with no complex custom field structures. Migrations that include document binary exports, larger record volumes, or Crelate custom field configuration across multiple object types move to four to six weeks. The migration timeline is shorter than a typical HRMS-to-HRMS project because the structural overlap between greytHR and Crelate is minimal; we are not migrating payroll runs, leave balances, attendance records, or statutory compliance data to Crelate.
