Overview

What this migration involves

Moving from Sloneek to BambooHR is a platform migration that requires export-based extraction from Sloneek due to its undocumented API, followed by structured import into BambooHR's REST API. Sloneek organizes employee data across core HR, ATS, attendance, performance, and payroll modules, each with its own field schema that varies by plan tier; BambooHR consolidates these into a unified HRIS with employee records, onboarding, time-off, and benefits as core objects. We handle the full lifecycle data transfer including custom field discovery and mapping, GDPR consent flag preservation, and the Attendance 2.0 schema split that coexists in live Sloneek tenants. Workflows, AI automations, and approval chains do not migrate as code; we deliver a written inventory for your admin to rebuild in BambooHR's template-driven system. BambooHR's well-documented API and custom field builder give us a clear import path once the source data is extracted and validated.

Sloneek

What's pushing teams away

  • Complex feature depth creates a steep learning curve for administrators new to HRIS systems, particularly around workflow configuration and module interconnections.
  • Document management restricted to PDF format only, frustrating teams that need to store Word documents, spreadsheets, or image-based records as employee files.
  • API is not publicly documented, blocking automation and integration use cases that require programmatic access to employee records or attendance data.
  • Some modules (ATS, advanced performance, payroll) require higher plan tiers, creating feature gaps for customers who expected full coverage at the base price.
  • Limited third-party integrations outside of Slack and JIRA, making it difficult to connect Sloneek data into broader analytics or finance tooling.

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 Sloneek objects map to BambooHR

Each row shows how a Sloneek 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.

Sloneek

Employees

maps to

BambooHR

Employee

1:1
Fully supported

Sloneek employee profiles (name, contact, job title, department, location, employment dates) map directly to BambooHR Employee records. Custom fields on Sloneek employee profiles are discovered during scoping, typed using BambooHR's Custom Field Builder (text, number, date, dropdown, checkbox, or employee-dependent types), and imported as BambooHR custom fields. We preserve the employee's status (active, inactive, terminated) and any GDPR consent flags as BambooHR custom fields for compliance continuity.

Sloneek

Organizational Structure

maps to

BambooHR

Location and Department

1:1
Fully supported

Sloneek departments, cost centers, and org chart hierarchies export as structured CSV with parent-child relationships. We reconstruct these in BambooHR as Locations (physical work sites) and Departments (cost-center groupings), and restore reporting lines by setting each employee's department and supervisor field against the resolved BambooHR employee records. Org chart order is preserved in a custom ordering field for post-migration reconstruction if needed.

Sloneek

Documents

maps to

BambooHR

Employee Files

1:1
Mapping required

Sloneek trust-box documents migrate as file attachments on the corresponding BambooHR employee record. We flag every non-PDF attachment in the source data (Sloneek accepts PDF only) and alert the customer during scoping that these files require pre-conversion before import; BambooHR accepts multiple formats. E-signature metadata on documents migrates as a note field for the customer's admin to act on in BambooHR's e-sign workflow.

Sloneek

Absences

maps to

BambooHR

Time Off

1:1
Fully supported

Sloneek absence requests, accrual balances, leave types, and approval statuses map to BambooHR Time Off. We map Sloneek leave categories (vacation, sick, parental, unpaid) to BambooHR's Time Off types, and carry the accrual balance as of the migration date into BambooHR's starting balance field. Approval history and notes migrate as BambooHR Time Off request comments for audit continuity.

Sloneek

Attendance Records (dual schema)

maps to

BambooHR

Time Tracking

1:1
Fully supported

Sloneek's ongoing Attendance 2.0 rollout means a single tenant may contain records in both the old and new attendance schema with different field names and structures. We detect which schema each record uses at export time, normalize both schemas into a unified format, and import the combined history into BambooHR Time Tracking. The migration date determines which records qualify for accrual carry-forward versus history-only import. Records are never dropped during this transition window.

Sloneek

ATS Candidates

maps to

BambooHR

Job Applicants

1:1
Mapping required

Sloneek ATS candidate records (including resumes, notes, GDPR consent flags, and recruitment pipeline stage) map to BambooHR Job Applicants. Candidate sourcing channel, application date, and stage history migrate as BambooHR application status and a custom stage-history field. GDPR consent timestamps and opt-out flags carry forward as BambooHR custom fields on the applicant record. The customer may need to reconfigure BambooHR's hiring pipeline stages to match Sloneek's stage names; we document the mapping in the migration handoff.

Sloneek

Performance Reviews

maps to

BambooHR

Performance Reviews

1:1
Fully supported

Completed Sloneek performance review cycles (360-degree feedback, goals, ratings) migrate as BambooHR Performance Review records. In-progress and draft reviews are migrated as historical data with a status flag but are not set as active BambooHR review cycles; the customer's HR admin activates cycles post-migration. Rating scales are mapped to BambooHR's rating fields, with any non-matching scale values preserved in a custom notes field.

Sloneek

Compensation History

maps to

BambooHR

Paychange

1:1
Mapping required

Sloneek salary, bonus, and deduction history migrate as BambooHR Paychange records where available on the customer's plan tier. Paychange entries carry effective date, pay amount, and change reason. Compensation records that Sloneek stores in its payroll module may require separate export confirmation depending on the customer's Sloneek plan tier; we verify payroll module access during discovery and include compensation in scope only when data is confirmed present.

Sloneek

Custom Fields

maps to

BambooHR

Custom Fields

lossy
Mapping required

Sloneek custom fields on employee profiles and select modules are discovered during scoping via export analysis. Each custom field's type (text, numeric, dropdown, date, boolean) is inferred from the data values and mapped to an equivalent BambooHR custom field type. We use BambooHR's Custom Field Builder (accessible to admins without a support request per their 2025 product update) to provision destination fields before record import. Fields without a clear BambooHR equivalent are documented as unmapped in the handoff with an explanation of why no target field exists.

Sloneek

Assets

maps to

BambooHR

Assets

1:1
Fully supported

Company assets assigned to employees in Sloneek (equipment, licenses, access credentials) migrate as BambooHR Asset records linked to the corresponding employee. Asset ID, name, type, assigned date, and return status transfer as BambooHR asset fields. Any asset with a pending assignment at migration time is flagged in the reconciliation report for the customer's admin to complete post-migration.

Pair-specific challenges

  • Sloneek has no public API — extraction requires export workarounds

    Sloneek does not publish API documentation or a developer portal. We cannot make authenticated API calls to pull data programmatically, so we rely on Sloneek's export utilities and manual data dumps for scoping. Before migration begins, we must request CSV or bulk export access through their support channel, which adds three to seven business days to the pre-migration phase. We confirm which data modules are active and plan-gated during discovery so that missing data objects (ATS, payroll, performance on lower tiers) are excluded from the contract upfront rather than discovered mid-project.

  • Sloneek stores PDF documents only — non-PDF files require pre-conversion

    Sloneek's document management module accepts only PDF files for employee records and the trust box. Scanned documents, Word files, spreadsheets, and images uploaded to Sloneek cannot be re-exported as-is. During scoping we flag every non-PDF attachment in the source data and alert the customer that these must be converted before they can be imported into BambooHR. BambooHR accepts multiple file formats, so the pre-conversion work is a customer-side action before migration day to avoid import rejection.

  • Sloneek attendance data spans two schemas simultaneously

    Sloneek's Attendance 2.0 rollout runs the old and new attendance modules in parallel for several months per their December 2025 release notes. A single tenant may contain attendance records split across two schemas with different field names, date formats, and record structures. We detect the schema version on a per-record basis at export time, normalize both schemas to a unified intermediate format, and import the combined history into BambooHR Time Tracking without dropping any records from either system.

  • BambooHR plan tiering gates some HRIS features

    BambooHR's Core plan includes employee records, hiring and onboarding, time-off, and benefits tracking. Performance management (goals, 360-degree reviews) and compensation management are Pro and Elite plan features respectively. If the customer activates performance or compensation modules in Sloneek and expects full parity in BambooHR, the BambooHR plan upgrade cost falls outside the migration fee. We verify the destination BambooHR plan tier during scoping and flag any feature gaps before the migration contract is signed.

Migration approach

Six steps for a successful Sloneek to BambooHR data migration

  1. Discovery and export access request

    We audit the customer's Sloneek tenant for active modules (core HR, ATS, attendance, performance, payroll), custom field schema, document attachment volume, and plan tier. Because Sloneek has no public API, we submit a support request to obtain CSV or bulk export access and confirm which modules are gated by the current plan tier. We also verify the BambooHR destination plan tier and identify any features (performance reviews, compensation management) that require an upgrade before their data objects are in scope. Discovery output is a written migration scope with record counts per object and a list of any missing source data due to plan tier gaps.

  2. Data extraction and schema mapping

    We extract employee records, organizational structure, absence balances, attendance history, ATS candidates, performance reviews, and compensation data from Sloneek using the confirmed export mechanism. Custom fields are discovered from the export schema and mapped to BambooHR field types. Where Sloneek's Attendance 2.0 and legacy attendance schemas coexist, we separate records by schema version and normalize field names to a unified intermediate format before any transformation. Non-PDF document attachments are flagged with file type, original filename, and employee association for the customer's pre-conversion task list.

  3. Destination schema provisioning

    We provision the BambooHR destination schema using the API: Departments, Locations, custom fields (via the Custom Field Builder), and Time Off types are created before any record import begins. BambooHR's Custom Field Builder is accessible to admins directly, so custom fields are provisioned by the customer or by us with delegated admin access. Time Off type names are matched to Sloneek leave categories, and accrual carry-forward amounts are set to the balance as of the migration date.

  4. Sandbox validation and reconciliation

    We run a full migration into the customer's BambooHR sandbox environment using production-like data volume. The customer's HR lead spot-checks 25-50 employee records against the Sloneek source, verifies absence balances, confirms ATS candidate pipeline mapping, and reviews document attachment availability. Any field mapping corrections, missing data gaps, or schema adjustments are resolved in sandbox before production migration begins. No data is modified in the production BambooHR environment until sandbox sign-off is received.

  5. Production migration in dependency order

    We run production migration in dependency order: Locations and Departments first (as reference data), then Employees with custom fields and reporting lines resolved, Time Off balances and history, ATS Candidates with GDPR flags and pipeline stages, Performance Review records, Compensation Paychange entries, and Attendance history (both schemas normalized). Document attachments upload in parallel with employee records, with non-PDF files held until pre-conversion is confirmed complete. Each phase emits a row-count reconciliation report before the next phase begins.

  6. Cutover, validation, and handoff

    We freeze writes in Sloneek during cutover and run a final delta migration of any records modified during the migration window. BambooHR becomes the system of record once the delta is confirmed. We deliver a written inventory of Sloneek workflows, approval chains, and Sloneek Intelligence AI automations requiring rebuild in BambooHR (which uses a template-driven workflow model rather than a code-based automation builder). We support a one-week post-migration window to resolve any data reconciliation issues raised by the customer's HR team.

Platform deep dives

Context on both ends of the pair

Source

Strengths

  • All-in-one platform covers the full employee lifecycle from recruitment to offboarding without requiring separate vendor products.
  • Strong EU/GDPR compliance with automated consent management, retention periods, and data anonymization features baked into the ATS and core HR modules.
  • Competitive pricing starting at €6 per user per month, positioning it between free-tier tools and enterprise HRIS platforms.
  • Sloneek Intelligence AI assistant provides a conversational interface across employee data, enabling bulk operations without manual UI work.
  • Central European origin means EU-local data residency options and a product roadmap oriented toward EU regulatory requirements.

Weaknesses

  • API is not publicly documented, limiting automated migration options and requiring export workarounds for programmatic data extraction.
  • PDF-only document restriction narrows what can be transferred as employee file attachments.
  • Attendance 2.0 migration is ongoing — old and new attendance schemas coexist in live tenants, requiring schema detection before migration scoping.
  • Feature depth creates a steeper learning curve for small teams or HR administrators transitioning from simpler payroll-only tools.
  • Third-party integrations are limited to Slack and JIRA, with no published API for connecting BI, finance, or ERP systems.

Destination

Strengths

  • Single platform consolidating ATS, onboarding, HR records, payroll, and time-off reduces system sprawl for SMBs.
  • Fast implementation — BambooHR reports four to six weeks from kickoff to go-live for most customers.
  • Per-employee pricing with automatic volume discounts makes cost predictable as headcount grows.
  • Strong customer support reputation (Support Heroes) cited consistently across G2, Capterra, and direct testimonials.
  • Well-documented API with UTF-8 encoding, clear field types, and HTTPS-only access.

Weaknesses

  • Mobile application is significantly limited compared to the desktop experience, frustrating remote and field workers.
  • Companies above 150–200 employees frequently outgrow the platform's feature depth and customization surface.
  • Limited advanced reporting and analytics compared to enterprise HR platforms — custom report building is the ceiling.
  • PTO and profile customization are pain points — non-standard accrual policies and complex org structures require workarounds.
  • Document management and attachment handling lack the granularity of dedicated document-centric HR systems.

Most migrations land between four and six weeks for accounts under 500 employees with core HR, absences, and document data. Migrations that include ATS candidate records, compensation history, custom fields across multiple modules, and attendance data from both Sloneek schemas extend to eight to twelve weeks because of schema discovery overhead and the attendance dual-schema normalization work. Sloneek's undocumented API adds three to seven business days to the pre-migration phase for export access confirmation before any data extraction begins.
