Overview

What this migration involves

Moving from SeamlessHR to Crelate is a platform-type migration that separates recruiting data from a full HRMS into a dedicated ATS/CRM. SeamlessHR bundles recruitment with payroll, performance management, and employee records for African markets; Crelate is a US-focused recruiting platform with ATS, CRM, and sourcing unified in one interface. We migrate the candidate database, job records, workflow stage history, and attachments. Employee records, leave balances, and payroll data do not map to Crelate's schema and are flagged as out-of-scope during scoping. The two most significant migration risks are SeamlessHR's undocumented API rate limits and the need to extract SeamlessHiring custom field definitions before importing values into Crelate. Workflow routing logic does not migrate; we deliver a written inventory of configured approval chains for the customer's admin to rebuild in Crelate.

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.

Why teams make this switch

Two sides of the same decision

SeamlessHR

What's pushing teams away

  • Exporting exited employee records requires a separate workflow from active employee exports, and customers report confusion about which data is retained versus purged at termination.
  • Custom fields on requisitions are supported but lack a standardized import template, forcing manual re-entry of custom properties during system transitions.
  • API documentation is sparse on bulk export endpoints, making programmatic data extraction dependent on support-assisted exports rather than self-service.
  • Reports and analytics are tier-gated with Advanced Reports only available on higher plans, limiting exit visibility for customers on the Lite tier.
  • Integration ecosystem is narrower than global HRMS competitors, with fewer pre-built connectors to African banking and benefits providers.

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 SeamlessHR objects map to Crelate

Each row shows how a SeamlessHR 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.

SeamlessHR

Candidate / Applicant

maps to

Crelate

Candidate

1:1
Fully supported

SeamlessHR's applicant records from SeamlessHiring map directly to Crelate's Candidate object. The full name, email, phone, current company, current title, source channel, and application date transfer 1:1. We resolve the Crelate Candidate unique ID at import time for use as the parent reference on all related objects. Any applicant with no email is flagged as a potential duplicate and held in a review queue before insert.

SeamlessHR

Employee

maps to

Crelate

(Out of scope)

lossy
Fully supported

SeamlessHR Employee records do not map to any Crelate object. Crelate is an ATS/CRM with no HRIS or employee record layer. If the customer runs dual systems (Crelate for recruiting, SeamlessHR for payroll and HRIS), we document the split and advise the customer to provision a separate SeamlessHR Lite or Core instance for ongoing employee management. Historical employee records with performance data are flagged as not migratable to Crelate's schema.

SeamlessHR

Job Requisition

maps to

Crelate

Job

1:1
Fully supported

SeamlessHR requisitions map to Crelate Jobs. The requisition title, description, location, employment type (full-time, contract), and department transfer. Job status (open, filled, on hold, closed) maps directly. We extract the workflow stage name and stage order from SeamlessHiring to rebuild the equivalent pipeline stage in Crelate's ATS pipeline configuration before migration.

SeamlessHR

Workflow Stage (SeamlessHiring)

maps to

Crelate

Pipeline Stage

lossy
Fully supported

SeamlessHiring stages are an ordered sequence tied to each applicant. We extract stage names, order index, and the stage each applicant has passed through, then configure matching pipeline stages in Crelate's ATS. The candidate's current stage migrates as a Crelate Activity note on the Candidate record since Crelate does not have a native workflow stage history object. Customers who rely on complex conditional stage routing document it during scoping for manual rebuild in Crelate's workflow automation.

SeamlessHR

Organization Structure

maps to

Crelate

(Out of scope)

1:1
Fully supported

SeamlessHR org chart and department hierarchy do not map to Crelate's schema. Crelate has no organizational structure object. If the customer uses departments as job classification metadata, we map the SeamlessHR department name to a Crelate custom field on the Job record. Parent-child reporting relationships are preserved as a written document for the customer's admin to re-establish in their retained HRIS platform.

SeamlessHR

Leave Management

maps to

Crelate

(Out of scope)

1:1
Fully supported

SeamlessHR leave balances, entitlement policies, and request history have no Crelate equivalent. Crelate is ATS-only. Leave data is flagged as out-of-scope during discovery. If the customer uses SeamlessHR specifically for leave management and Crelate for recruiting, we recommend retaining SeamlessHR Lite for leave management or migrating leave data to a dedicated leave management platform as a parallel engagement.

SeamlessHR

Payroll Records

maps to

Crelate

(Out of scope)

1:1
Mapping required

Historical payslips and payroll runs do not map to Crelate's ATS schema. If the customer runs SeamlessHR payroll and Crelate recruiting in parallel, payroll records stay in SeamlessHR. We document the payroll module boundary explicitly in the migration scope and flag that compensation data attached to candidate records (for contractor or contract-to-hire placements) may need to be stored as a custom field on the Crelate Candidate record rather than in a native payroll object.

SeamlessHR

Custom Fields (Requisition)

maps to

Crelate

Custom Fields (Job)

lossy
Fully supported

SeamlessHR custom fields on requisitions require schema extraction before migration. We retrieve the field definition list via API first (field name, field type), pre-create matching custom fields in Crelate Job, then pull the values per requisition record. If a custom field type (date, number, text, dropdown) has no direct Crelate equivalent, we map to the nearest Crelate type and flag the mapping in the reconciliation report. Customer must pre-create any custom fields in Crelate before the migration run begins.

SeamlessHR

Custom Fields (Employee)

maps to

Crelate

Custom Fields (Candidate)

lossy
Fully supported

SeamlessHR custom fields on employee profiles map to Crelate Candidate custom fields if the employee was previously an applicant in SeamlessHR. We extract the field definition list first, pre-create matching custom fields in Crelate Candidate, then import values. This mapping applies only to applicants with an existing SeamlessHR candidate record; pure HRIS custom fields on employee-only records are out of scope.

SeamlessHR

Documents (Candidate)

maps to

Crelate

Attachments (Candidate)

1:1
Fully supported

Candidate documents (resumes, cover letters, portfolio files) attached to SeamlessHR applicant profiles migrate as Crelate Candidate attachments. We extract document metadata and binary blobs, map the file name, and attach to the corresponding Crelate Candidate record. Large attachments (over 10 MB per file) are flagged for manual re-upload if Crelate's file size limits are encountered. We preserve the original file name and upload timestamp.

SeamlessHR

Performance Reviews

maps to

Crelate

(Out of scope)

1:1
Mapping required

SeamlessHR performance and potential ratings, review cycles, and goal data do not map to Crelate's ATS schema. This data is available on SeamlessHR Core tier and above. We flag it as out-of-scope and recommend the customer retains SeamlessHR Core or migrates performance data to a dedicated performance management platform (Lattice, BambooHR, Workday) as a parallel engagement.

SeamlessHR

Approval Workflows

maps to

Crelate

(Out of scope)

1:1
Not supported

SeamlessHR approval chains and routing logic do not migrate. We do not migrate workflow definitions. We deliver a written inventory of every configured approval chain in SeamlessHR (which stages require approval, who the approver role is, what conditions trigger escalation) so the customer's admin can rebuild equivalent automation in Crelate's workflow builder post-migration.

Pair-specific challenges

  • Employee and HRIS data cannot migrate to Crelate

    Crelate is an ATS/CRM with no HRIS, payroll, or employee record layer. Any migration from SeamlessHR to Crelate must be scoped as a recruiting-data-only migration. Employee records, leave balances, payroll history, performance reviews, and organization structure do not map to any Crelate object. Organizations that rely on SeamlessHR for payroll and HRIS alongside recruiting must plan a dual-system operation (Crelate for recruiting, SeamlessHR or a replacement HRIS for HRIS) before migration begins. We flag the data-model boundary during discovery and document the split explicitly in the scope agreement.

  • SeamlessHR exited employee export is a separate workflow

    SeamlessHR treats terminated employees as a distinct data path from active employees. If the migration scope includes historical applicants who were hired and then exited in SeamlessHR, their records require a separate export request. Historical applicant records attached to exited employees are at risk of being missed if both export paths are not explicitly requested during scoping. We always request both active and exited employee exports and cross-reference by employee ID to ensure no applicant records are orphaned. Exited employee records that were never applicants (pure HRIS terminations) are out of scope for Crelate migration regardless.

  • SeamlessHR API rate limits are undocumented

    The SeamlessHR API documentation does not publish rate limits or dedicated bulk export endpoints. This means migration runs may encounter undocumented throttling without warning. We implement adaptive request pacing with exponential backoff and monitor for 429 responses. If throttling is detected, the migration run pauses and resumes automatically to protect data integrity. For large migrations (over 10,000 applicant records), we may require support-assisted export from SeamlessHR as an alternative extraction path if API-based extraction produces incomplete results.

  • Custom fields require pre-creation in Crelate before import

    Crelate's import process requires custom fields to exist in the schema before data values can be loaded. We retrieve the SeamlessHR custom field definition list (field name and type) via API before any data extraction, then pre-create matching fields in Crelate Job and Candidate objects before the import run. If the customer has not pre-created fields in Crelate, any values for undefined custom fields are skipped and logged. We include a pre-flight check that validates all custom fields exist in Crelate before beginning the data load.

  • Workflow routing logic does not migrate

    SeamlessHR approval chains and conditional routing logic are not portable to Crelate. We do not migrate workflow definitions as code. We deliver a written inventory of every configured approval chain in SeamlessHR (stage, approver role, condition, escalation path) for the customer's admin to rebuild in Crelate's workflow builder. Any conditional stage routing that moves applicants automatically based on field values requires manual configuration in Crelate post-migration.

Migration approach

Six steps for a successful SeamlessHR to Crelate data migration

  1. Discovery and data boundary definition

    We audit the source SeamlessHR portal for active and historical applicant records, job requisitions, workflow stage names and sequences, custom field definitions (employee and requisition), document attachment volume, and the SeamlessHR module footprint (HRIS only, HRIS plus Payroll, HRIS plus Performance). We pair this with a data boundary definition: recruiting data (applicants, jobs, attachments) migrates to Crelate; employee records, payroll, leave, performance, and org structure are documented as out-of-scope with a recommendation to retain a scaled SeamlessHR Lite or Core instance for HRIS. The discovery output is a written migration scope with record counts per object and a dual-system architecture recommendation.

  2. Schema extraction and Crelate pre-configuration

    We extract SeamlessHR custom field definitions via API before any data extraction begins. We then pre-create matching custom fields in Crelate Job and Candidate objects. We configure Crelate pipeline stages to match SeamlessHiring workflow stages in name and order. We extract the complete stage sequence and map each applicant's current stage to a Crelate Activity note. If Crelate does not have an equivalent field type for a SeamlessHR custom field, we document the mapping and apply the closest Crelate type. The customer must provision at least one Crelate user account before this step begins.

  3. Sandbox migration and reconciliation

    We run a full migration into Crelate's sandbox or trial environment using production data volume. The customer's recruiting operations lead reconciles record counts (candidates in, jobs in, attachments in, stage history), spot-checks 25-50 random candidates against the SeamlessHR source, and signs off the schema and field mapping before production migration begins. Any custom field mapping corrections, stage name adjustments, or duplicate handling rules are resolved here, not in production.

  4. Candidate and job bulk import

    We run the production migration in dependency order: Jobs first (since candidates attach to a Job), then Candidates with the Job reference resolved, then custom field values per record, then attachment metadata and binary blobs. Each phase emits a row-count reconciliation report before the next phase begins. We use Crelate's REST API with adaptive request pacing and exponential backoff for all imports. Large attachment files (over 10 MB) are flagged for manual re-upload if Crelate's file size limits are encountered.

  5. Workflow and stage history handoff

    We deliver the SeamlessHR approval chain inventory as a written document listing each configured workflow, its trigger, approver roles, conditions, and recommended Crelate equivalent. We also deliver the SeamlessHiring stage history as a Crelate Activity note per candidate documenting which stages each applicant passed through. The customer's admin uses these documents to rebuild workflow automation in Crelate post-migration. We do not rebuild automation inside the migration scope.

  6. Cutover and dual-system validation

    We freeze SeamlessHR writes during cutover, run a final delta migration of any candidate records or job updates made during the migration window, then enable Crelate as the recruiting system of record. We validate that all candidate records, job records, attachments, and stage history are accessible and searchable in Crelate. We support a one-week hypercare window to resolve any reconciliation issues raised by the recruiting team. We do not provide ongoing admin support, training, or workflow rebuild as part of the migration scope; these are separate engagements.

No. Crelate is a recruiting ATS and CRM with no HRIS, payroll, or employee record layer. Employee profiles, leave balances, payroll history, performance reviews, and organizational structure in SeamlessHR do not map to any Crelate object. If your organization uses SeamlessHR for both recruiting and HRIS, you need to plan a dual-system operation: Crelate for recruiting and a retained HRIS (SeamlessHR Lite or a replacement) for payroll and employee records. We document the data split explicitly during scoping and flag which SeamlessHR modules should remain active post-migration.
