Overview
Moving from ApplicantStack to BambooHR combines a purpose-built ATS with a full HRIS platform, replacing a standalone recruiting tool with an integrated system that handles hiring, onboarding, employee records, time-off, and benefits in one place. ApplicantStack has no real-time API migration endpoint—all data extraction relies on the built-in Reports builder outputting CSV or Excel, which we parse and normalize into structured records before importing through BambooHR's API. Candidate records, questionnaire responses, and pipeline stage histories migrate 1:1; email templates and custom form content map as documentation for manual rebuild. We do not migrate ApplicantStack Workflows, automated candidate communication sequences, or job board distribution configurations as code; we deliver a written inventory of these for the customer's admin to reconstruct in BambooHR's hiring workflow builder.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.

Object mapping
Each row shows how a ApplicantStack 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.
ApplicantStack
Jobs/Positions
BambooHR
Job
1:1ApplicantStack Positions map directly to BambooHR Job records. We extract job title, description, status (open, closed, archived), job board distribution settings (as content only), and opening count. BambooHR enforces a job opening limit by plan tier (Core: 5, Pro: 25, Elite: 50) which we confirm during scoping. If the customer's active job count exceeds the target tier, we flag the discrepancy and recommend a plan upgrade before migration. Job board distribution settings do not migrate as configurations; the job description content migrates as content and the customer republishes to the desired boards in BambooHR.
ApplicantStack
Candidates
BambooHR
Application
1:1ApplicantStack Candidate records map to BambooHR Application records linked to a Job. We extract name, contact information (email, phone, address), application date, resume file, current pipeline stage, source attribution, notes, and custom property responses. ApplicantStack's unreliable duplicate detection means we run dedup logic during transformation matching by email address, normalized name, and phone number. Likely duplicates are flagged for customer review before final import to prevent multiplying duplicate applications in BambooHR.
ApplicantStack
Questionnaires/Custom Forms
BambooHR
Custom Application Fields
lossyApplicantStack Questionnaire responses are stored as field-value pairs on the Candidate record. We extract all custom field responses and map them to custom fields on the BambooHR Application object. If the destination custom fields do not exist, we create them during the schema setup phase using BambooHR's custom field API. Dropdown, checkbox, and rating question types map to the corresponding BambooHR field types. The customer reviews the field mapping during sandbox validation to confirm that questionnaire logic maps correctly into BambooHR's application data model.
ApplicantStack
Hiring Pipeline Stages
BambooHR
Application Stage
lossyApplicantStack pipeline stages (Applied, Screening, Interview, Offer, Hired, Rejected) and any custom stages configured by the customer map to BambooHR Application Stage values. We export the full pipeline configuration including stage names, ordering, and any custom stage properties. BambooHR's ATS uses a predefined stage model; we map each ApplicantStack stage to the nearest BambooHR equivalent and document any stages that cannot map directly for the customer's admin to resolve in BambooHR's settings post-migration.
ApplicantStack
User Accounts (Recruiters/Hiring Managers/Admins)
BambooHR
Employee (as hiring team members)
1:1ApplicantStack user roles (Administrator, Recruiter, Hiring Manager) control access to jobs and candidates. We export role assignments and map them to BambooHR Employee records for hiring team members. BambooHR's ATS uses the standard Employee object for hiring team assignment rather than a separate user object. Email address is the matching key. Any ApplicantStack user without a corresponding BambooHR Employee record goes to a reconciliation queue for the customer's admin to provision before candidate assignment migration proceeds.
ApplicantStack
New Hire Records (from ApplicantStack Onboard)
BambooHR
Employee + Onboarding Task
1:manyWhen ApplicantStack Onboard is active, new hire onboarding packets include I-9 data, tax form acknowledgments, and custom onboarding documents. We extract these as structured records and separate document blobs. I-9 and tax form data migrate as BambooHR Employee custom fields or document attachments; onboarding task checklists migrate as BambooHR Onboarding Task records. The separation between ApplicantStack Recruit (candidate data) and ApplicantStack Onboard (new hire data) requires confirming which SKU is active during discovery to calibrate scope and avoid over-estimating available data.
ApplicantStack
Attachments (Resumes, Cover Letters)
BambooHR
Application File Attachment
1:1Resume files, cover letters, and uploaded documents extract from ApplicantStack candidate records as binary blobs. We preserve file names and attach them to the corresponding BambooHR Application record using BambooHR's file attachment API. File type, original file name, and upload timestamp are preserved in the attachment metadata. If the candidate record has no resume on file, we migrate a placeholder note indicating no resume was attached in ApplicantStack.
ApplicantStack
Email Templates
BambooHR
Email Template (documentation only)
1:1ApplicantStack stores email templates used in candidate communication sequences. We export template content and map variable placeholders to a reference document. The automated trigger logic, send conditions, and timing sequences do not migrate as code. BambooHR's ATS includes email and offer letter templates; we provide the customer with a template content inventory mapped to the closest BambooHR equivalent so the admin can rebuild communication sequences in BambooHR's workflow builder.
ApplicantStack
Custom Properties (Employer-Defined Fields)
BambooHR
Custom Fields on Application
lossyCustom properties added to Candidates or Jobs beyond ApplicantStack's standard schema are captured as key-value pairs. We map them to custom fields on the corresponding BambooHR object during schema setup, creating the destination properties via BambooHR's API before import begins. Field type mapping follows the nearest equivalent: ApplicantStack text fields become BambooHR text fields, dropdown fields become option lists, and numeric fields become number fields. Multi-select custom properties in ApplicantStack map to multi-select picklists in BambooHR.
ApplicantStack
Tags/Labels
BambooHR
Tags on Application
1:1Candidate tags and job labels export from ApplicantStack as flat tag arrays. We preserve all tags and apply them to the corresponding Application records in BambooHR. Tag merge logic handles cases where identical tags exist under slightly different names in the source data. BambooHR's tag model supports tagging applications by keyword; the customer can use tags to replicate ApplicantStack's label-based filtering workflows.

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.
ApplicantStack gotchas
Trial limits visibility to first 100 candidates
Pricing is per-user including all roles
Export is report-based, not a live database query
Duplicate detection gaps create record overlap
Onboarding module is a separate product SKU
BambooHR gotchas
Undocumented API rate limits can trigger 503 errors
Per-employee pricing model requires active record count verification
API credentials must be sent on every request to avoid extra round trips
Custom field schema varies per account and requires manual inventory
Document and attachment exports are not covered by standard report exports
Pair-specific challenges
Migration approach
Discovery and plan confirmation
We audit the source ApplicantStack account across product SKU (Recruit only, Onboard only, or bundle), user count, active job postings, candidate volume, custom questionnaire schemas, pipeline stage configuration, and onboarding record count. We pair this with a BambooHR plan assessment: Core ($10/employee, 5 job openings) suits small teams with low-volume hiring; Pro ($17/employee, 25 openings) handles moderate growth; Elite ($25/employee, 50 openings) covers higher-volume recruiting. We confirm the job opening count against the target BambooHR tier and flag any discrepancy requiring plan upgrade before migration scope is finalized.
Report generation and CSV extraction
ApplicantStack has no API; we work with the customer's ApplicantStack administrator to generate the necessary export reports via the Reports builder. We guide them through building custom report templates that cover Jobs, Candidates, Questionnaire responses, Pipeline Stages, User assignments, and (if applicable) Onboard records. We validate the CSV structure against our migration schema, identifying any missing fields or malformed rows before parsing begins. This pre-migration preparation step adds one to three days to the project timeline that is not required when migrating from API-first platforms.
Schema setup in BambooHR
We configure the destination BambooHR account: creating custom fields on the Application object to match ApplicantStack custom questionnaire schemas, configuring pipeline stage values to map from ApplicantStack stages, and provisioning Employee records for hiring team members referenced in the candidate migration. Schema setup runs against a BambooHR sandbox or staging environment first for validation. We coordinate with the customer's BambooHR admin to confirm API key access and permissions before schema deployment.
Sandbox migration and deduplication review
We run a full migration into the customer's BambooHR sandbox environment using production-like data volume. Candidate deduplication runs during this phase, matching by email address, normalized name, and phone number to catch ApplicantStack records that appear to be duplicates due to its unreliable duplicate detection. We flag likely duplicates for the customer's review before final import. The customer's HR lead spot-checks 20-40 random application records against the ApplicantStack source and approves the schema and mapping before production migration begins.
Production migration in dependency order
We run production migration in record-dependency order: Employee records for hiring team members (first, so Hiring Manager lookups are satisfied), Jobs (with job opening count validated against BambooHR plan tier), Applications (with custom field responses mapped, stage assignments configured, and file attachments preserved), and Onboarding records (if ApplicantStack Onboard is in scope, separated into Employee custom fields and Onboarding Task records). Each phase emits a row-count reconciliation report before the next phase begins. We use BambooHR's REST API with rate-limit handling and exponential backoff for record inserts.
Cutover, validation, and template handoff
We freeze ApplicantStack writes during cutover and run a final delta migration of any records modified during the migration window. We enable BambooHR as the system of record and deliver the email template content inventory and workflow rebuild documentation to the customer's admin team. We support a three-day hypercare window where we resolve any reconciliation issues. We do not rebuild ApplicantStack automated sequences or communication workflows inside the migration scope; that work is handled by the customer's BambooHR admin using BambooHR's built-in workflow builder.
