Overview

What this migration involves

Moving from Sympa to BambooHR is a migration from a multi-country enterprise HRIS to a mid-market platform built for small and mid-sized teams. Sympa excels at global compliance, multi-country payroll, and deep organizational hierarchies; BambooHR excels at ease of use, transparent pricing, and a well-documented REST API. We handle the schema reconciliation between Sympa's org units, effective-dated compensation records, and custom fields and BambooHR's flatter employee data model, preserving employment dates, job titles, compensation snapshots, and document attachments where the destination supports them. We flag time-off balance differences (Sympa tracks accrual snapshots; BambooHR uses policy-based accrual configuration) and deliver a written map of any custom fields that require manual reconfiguration or manual data entry post-migration. Workflows, automations, and payroll integrations do not migrate; these are documented separately for the customer's HR admin to rebuild or reconfigure in BambooHR.

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

Sympa

What's pushing teams away

  • Pricing transparency is a recurring pain point — Sympa does not publish public pricing tiers, requiring a sales quote for every evaluation and making cost comparisons difficult.
  • Organizations with simpler HR needs find Sympa over-engineered for their use case, paying for multi-country and enterprise features they do not use.
  • Some users report that the breadth of configuration options creates complexity during initial setup and ongoing administration, slowing down HR teams unfamiliar with the system.
  • Integration setup, particularly for non-standard payroll or identity providers, can require technical resources and custom API work beyond what the wizards support.

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 Sympa objects map to BambooHR

Each row shows how a Sympa 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.

Sympa

Employee

maps to

BambooHR

Employee

1:1
Fully supported

Sympa Employee records map to BambooHR Employee. We map firstName, lastName, workEmail, jobTitle, department, hireDate, terminationDate, supervisorId, employmentStatus, and mobilePhone to BambooHR's equivalent fields. National ID, date of birth, and address fields map directly where present. We flag employees with missing required fields (workEmail, firstName, lastName) during pre-migration data profiling so the customer can clean or suppress before import. TerminationDate from Sympa maps to BambooHR's terminationDate field, and we set employmentStatus to Terminated for records with a populated terminationDate.

Sympa

Organizational Structure

maps to

BambooHR

Department and Supervisor

lossy
Mapping required

Sympa stores org units as parent-child hierarchies across countries and legal entities. BambooHR uses a flat department field plus a supervisor lookup on each Employee record. We extract the deepest-level org unit name from Sympa's hierarchy and map it to BambooHR department. If multiple levels are meaningful, we join them into a single string (e.g., 'Engineering - Frontend') or configure BambooHR's division field as a secondary level. Any Sympa org unit that maps to no BambooHR equivalent is flagged for manual review during scoping.

Sympa

Compensation History

maps to

BambooHR

Pay Rate and Custom Fields

lossy
Mapping required

Sympa stores salary, bonus, and equity as effective-dated entries per employee with full historical timelines. BambooHR has a single payRate field plus optional custom fields; it does not have a native compensation history object. We extract the most recent compensation entry from Sympa and map it to BambooHR's payRate. For compensation history, we pre-create custom date and currency fields in BambooHR (e.g., salary_effective_date, salary_amount, bonus_amount) and map the full effective-dated timeline as multiple rows in those custom fields, or advise the customer to preserve the full history as an attached PDF report.

Sympa

Documents

maps to

BambooHR

Employee Files

1:1
Mapping required

Sympa attaches employee documents (contracts, certifications, compliance records) to Employee records. BambooHR supports employee file attachments. We migrate documents as files, mapping them to the corresponding BambooHR Employee's Files tab. We apply BambooHR's supported file format constraints (PDF, images, common office formats) and flag any binary or unsupported formats for manual handling. Document metadata (document type, issue date, expiry date) is preserved in the file description field or a custom field if the customer has configured one.

Sympa

Time-Off Balances

maps to

BambooHR

Time Off

lossy
Mapping required

Sympa tracks accrued time-off balances per employee per leave type as snapshot values at a point in time. BambooHR uses a policy-based time-off model with accrual configuration and optional balance import. We export Sympa's current balance snapshot as a CSV during pre-migration profiling and advise the customer on whether to import balances directly (if BambooHR's accrual policy supports it) or reconfigure accruals from scratch. We do not migrate accrual calculation rules because BambooHR's accrual engine handles these natively. The customer configures matching leave types in BambooHR's Time Off settings before balance import.

Sympa

Custom Fields

maps to

BambooHR

Custom Fields

1:1
Mapping required

Sympa allows tenant-specific custom fields on Employee and related objects without schema governance controls. BambooHR supports custom fields via the Custom Fields tab in Settings with a defined set of types (text, number, date, dropdown, checkbox, etc.). We perform a pre-migration custom field audit during scoping, export the full Sympa custom field inventory, cross-reference each against BambooHR's supported types, and map where a direct equivalent exists. Fields with no BambooHR equivalent are flagged as requiring a manual reconfiguration step or a custom field setup in BambooHR before migration. This audit is customer-specific and cannot be hardcoded because custom field names and values vary per Sympa tenant.

Sympa

Employment History

maps to

BambooHR

Job Title, Department, and Custom Fields

lossy
Mapping required

Sympa records job title changes, department transfers, and manager updates as effective-dated events per Employee with a full chronological timeline. BambooHR stores a single current jobTitle, department, and supervisor on each Employee record. We extract the most recent title and department from Sympa's employment history and map it to BambooHR's current field values. If the customer requires the full history, we create custom date-stamped fields (e.g., previous_title, previous_department, effective_date) and map the historical sequence as multiple rows, or preserve the full timeline as a linked document.

Sympa

Users and Roles

maps to

BambooHR

Employee with Access Level

1:1
Mapping required

Sympa assigns roles and permissions to Users who may not map 1:1 to Employee records. BambooHR ties system access directly to Employee records with permission levels (Employee, Manager, Admin). We distinguish active system users from purely administrative employee records in Sympa. Active users with a corresponding Sympa Employee record are mapped to BambooHR Employee records with an access level assigned. Users without an Employee record are provisioned as BambooHR employees with the appropriate access level. We resolve by email match and flag any duplicate email addresses before import.

Sympa

Payroll Integration Configuration

maps to

BambooHR

Payroll

1:1
Fully supported

Sympa integrates with third-party payroll providers across its integration marketplace. BambooHR integrates with a different set of payroll providers (Gusto, ADP, Paychex, OnPay). We do not migrate payroll integration configurations as these are provider-specific and require fresh setup in BambooHR. We document the current Sympa payroll provider and integration type in the migration inventory so the customer's HR admin can configure the equivalent in BambooHR post-migration.

Sympa

Time-Off Policies

maps to

BambooHR

Time Off Policies

lossy
Fully supported

Sympa maintains leave type configurations (PTO, sick leave, parental leave) with country-specific rules. BambooHR requires manual setup of Time Off policies with accrual rates, carryover rules, and eligibility criteria. We export the Sympa leave type inventory during scoping, document each policy's type and accrual rule, and deliver a written policy mapping table for the customer's HR admin to reconfigure in BambooHR's Time Off settings. We do not migrate policy rules as they are configuration rather than data.

Pair-specific challenges

  • Sympa has no public API documentation for schema discovery

    Sympa does not publish standalone API documentation, endpoint schemas, object field lists, or rate limits for independent developers to browse. During migration scoping, we request API credentials and perform a live schema discovery call against the customer's Sympa tenant to enumerate available objects and fields before designing the field mapping. This discovery step adds time that migrations from platforms with public API docs do not require. Customers who have never used Sympa's API may not know what API access their contract includes; we confirm API availability and credential provisioning during the first scoping call.

  • BambooHR custom fields use numeric IDs that vary per account

    BambooHR's Custom Report API and field endpoints reference custom fields by numeric field IDs fetched via GET /v1/meta/fields, and these IDs differ per BambooHR account. We cannot hardcode field IDs in migration scripts. During the scoping call, we fetch the customer's BambooHR meta/fields response to enumerate available field IDs, cross-reference them with the Sympa custom field audit, and build the mapping dynamically per customer. This per-customer field ID resolution is required before any custom field data is written to BambooHR.

  • Time-off balance migration depends on BambooHR accrual policy setup

    Sympa tracks accrued time-off balances as snapshot values at a point in time. BambooHR calculates accruals from policy rules rather than accepting direct balance imports by default. If BambooHR's Time Off module is configured with matching leave types and accrual policies, we can import current balances as entitlement values. If no matching policy exists, we export Sympa's balance snapshot as a CSV and advise the customer to configure BambooHR policies and re-enter balances manually post-migration. We flag the time-off balance handling decision during scoping so the customer has time to configure BambooHR Time Off policies before migration.

  • BambooHR employee endpoint returns all records in one response

    BambooHR's GET /v1/employees endpoint returns all employees in a single response without pagination. For large organizations, this response can be substantial (tens of MB). We handle this by streaming the response, splitting records for batch processing, and applying BambooHR's approximate rate limit of 100 requests per minute with exponential backoff on 503 responses. We do not use BambooHR's Data Export endpoint as a substitute because it is designed for full data dumps rather than targeted migration loads.

  • BambooHR uses HTTP Basic Auth with permission-based access

    BambooHR's REST API uses HTTP Basic Auth with an API key as the username and any non-empty string as the password. There is no OAuth 2.0. The API key inherits the permissions of the user account that generated it, with no separate scope model. We request a dedicated BambooHR service account with scoped permissions (Employee Admin or limited to required fields) rather than using an admin's personal API key. We coordinate with the customer's BambooHR admin to provision the migration service account and confirm the correct field-level permissions before migration begins.

Migration approach

Six steps for a successful Sympa to BambooHR data migration

  1. Discovery and Sympa API schema enumeration

    We request Sympa API credentials and perform a live schema discovery call against the customer's tenant to enumerate available objects, fields, and custom field inventories. We export the Sympa employee list, org unit structure, compensation history records, time-off balances, document inventory, and custom field list. We confirm API access scope with the customer (some Sympa contracts include read-only API access only) and identify any objects or fields that require alternative export methods (CSV, direct database read) if API access is constrained. We pair this with a BambooHR account setup confirmation and meta/fields fetch to enumerate BambooHR field IDs for custom field mapping.

  2. Custom field audit and field mapping design

    We cross-reference the Sympa custom field inventory (names, data types, picklist values) against BambooHR's supported custom field types (text, number, date, dropdown, checkbox, etc.). We flag any Sympa custom fields that lack a direct BambooHR equivalent and propose a reconfiguration approach (new BambooHR custom field, manual re-entry, or document preservation). We design the full field mapping specification including transformation rules for date formats, multi-select picklists, and numeric precision, and we confirm BambooHR field IDs for every custom field that will be written via the BambooHR API.

  3. BambooHR custom field and time-off policy setup

    Before any employee data is written to BambooHR, we pre-create all required custom fields via BambooHR's Settings > Custom Fields interface using the field IDs resolved in step one. If the customer opts to import time-off balances, we confirm that BambooHR Time Off policies are configured with matching leave types and advise the customer to set up accrual policies before the migration window. We provision the migration service account in BambooHR with the correct permissions for API access and confirm field-level read/write access before proceeding.

  4. Sandbox migration and reconciliation

    We run a full migration into the customer's BambooHR environment using a representative subset (or full dataset if the customer approves) to validate the field mapping, identify data quality issues, and confirm reconciliation counts. We check that employee records appear in BambooHR with correct names, job titles, departments, hire dates, and termination dates. We verify that custom field values are written to the correct BambooHR field IDs. The customer spot-checks 20-30 records against the Sympa source data and signs off the mapping before production migration begins.

  5. Production migration in dependency order

    We migrate in record-dependency order: employees first (with employment status resolved for active versus terminated), then organizational fields (department, supervisor), then compensation history (to custom fields or document attachment), then time-off balance snapshot (to BambooHR Time Off or CSV export for manual re-entry), then documents (file attachments), then any remaining custom fields. We apply BambooHR's rate limit of approximately 100 requests per minute with exponential backoff on 503 responses, and we batch records in groups of 50-100 for the BambooHR employee import API.

  6. Cutover, validation, and handoff

    We place a write-freeze on Sympa during the cutover window, run a final delta migration of any records modified during the migration, and confirm the employee record count matches between Sympa and BambooHR. We deliver a migration inventory document covering the time-off balance CSV (for manual import if applicable), the Sympa payroll integration documentation for the customer's admin to reconfigure in BambooHR, and the list of any Sympa custom fields that could not be migrated and require manual reconfiguration. We provide a one-week hypercare window to resolve post-migration reconciliation issues raised by the HR team.

Migrations under 100 employees with no compensation history and no document migration typically complete in three to five weeks. Migrations with compensation history (effective-dated salary and bonus records), multi-level org hierarchies, a large custom field inventory, or document attachments move to eight to twelve weeks. The primary time variable is the pre-migration custom field audit and Sympa API schema discovery, which is a customer-specific step that cannot be accelerated with generic templates.
