Overview
Moving from Checkwriters to BambooHR is a platform migration that separates payroll processing from HR record-keeping. Checkwriters consolidates both; BambooHR treats payroll as an optional module and positions itself as an HRIS with hiring, onboarding, and performance tools built in. The primary migration surface is employee data, accrued time-off balances, deduction and benefit elections, and historical pay stub references. Checkwriters stores payroll items with check-date ranges (start check date, end check date) rather than calendar dates, which requires a date-translation step during import. Historical payroll data has no API extraction path in Checkwriters; we coordinate with the customer's HR Admin to define and export the correct Report Writer reports before any import begins. Performance review records and onboarding task histories do not migrate because they exist in a proprietary Checkwriters format with no documented export endpoint; we deliver a written rebuild inventory instead.

Object mapping
Each row shows how a Checkwriters 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.
Checkwriters
Employee
BambooHR
Employee
1:1Checkwriters Employees map to BambooHR Employee records. Core fields (first name, last name, date of birth, hire date, termination date, job title, department, location, employment status) map directly. Checkwriters re-hire flags and employee ID are preserved in custom fields on the BambooHR Employee record. HR Admin access is required during scoping to enumerate all active custom field definitions before field-level mapping begins.
Checkwriters
Payroll Rates and Earnings
BambooHR
Pay Runs / Compensation Fields
1:1Checkwriters payroll items use check-date ranges (start check date, end check date) to define when a rate or earning type is active. We translate each rate's effective check-date window to a calendar effective date in BambooHR's pay run configuration. Pay types (regular, overtime, bonus, commission) map to BambooHR earnings types; the rate stored in the check-date record becomes the pay rate on the BambooHR Employee record.
Checkwriters
Accruals
BambooHR
Time-Off Accruals
1:1Checkwriters PTO, sick time, and Bereavement accrual balances map to BambooHR time-off policies. We identify the accrual policy type (annual reset vs. carry-forward) during scoping and configure BambooHR's accrual policy accordingly. Running balances are imported as initial balance values at cutover. Accrual rate and frequency information from Checkwriters translates to BambooHR's accrual rate configuration (hours per pay period, annual cap, rollover limits).
Checkwriters
Time-Off Requests
BambooHR
Time-Off Requests
1:1Historical time-off requests from Checkwriters (request date, request type, start date, end date, status, approver) migrate to BambooHR time-off records. Current pending requests are flagged during scoping for manual re-entry or coordinated approval timing around cutover. Request status transitions (approved, denied, cancelled) map directly to BambooHR time-off status values.
Checkwriters
Deductions and Benefits
BambooHR
Deductions / Benefits Tracking
1:manyCheckwriters deductions (pre-tax 401k, health insurance, FSA; post-tax wage garnishments) map to BambooHR deduction records tied to the employee. Benefit plan enrollments are mapped to BambooHR benefit plans, with the carrier name, plan ID, and coverage tier preserved. Open enrollment period flags and qualifying life event dates require date translation to BambooHR's benefits tracking module, which is an add-on outside Core.
Checkwriters
Custom Fields
BambooHR
Custom Fields
1:1Checkwriters company-level custom fields (text, date, dropdown, numeric) map to BambooHR employee custom fields with equivalent types. Discovery requires HR Admin-level access to the Checkwriters tenant during scoping. We enumerate all active custom field definitions, map field types to BambooHR field types, and import values at the employee record level during the main migration phase.
Checkwriters
Documents
BambooHR
Documents
1:1Employee documents (offer letters, signed agreements, I-9s, performance records) are stored in Checkwriters' Document Center with visibility restrictions. We extract file references and import metadata (document type, upload date, associated employee) into BambooHR Documents, preserving the document name and category. Document visibility settings are translated to BambooHR's employee document access controls. File content itself migrates as attachments.
Checkwriters
Pay Stubs and Historical Payroll
BambooHR
Pay Stubs / Payroll History
1:1Historical pay stub data must be pulled from Checkwriters via Report Writer, not via API, because no public bulk export endpoint exists. We coordinate with the customer's HR Admin to define the correct report types (earnings, taxes, deductions) and date ranges before extraction. W-2 and 1099 historical references migrate as payroll history records in BambooHR, with the pay date as the index date. If BambooHR Payroll is not in scope, we migrate pay stub references as document links only.
Checkwriters
Report Writer Exports
BambooHR
Reports (rebuild scope)
lossyCheckwriters Report Writer definitions cannot be migrated directly to BambooHR Reports because the reporting engines are structurally different. We extract the report definitions and column layouts during scoping and deliver a written mapping document showing which Checkwriters reports map to which BambooHR standard or custom reports. The customer's HR Admin rebuilds the reports in BambooHR's report builder post-migration.
Checkwriters
Onboarding Workflows
BambooHR
Onboarding (add-on)
lossyCheckwriters onboarding (available on HR Premier and above) includes document e-signature collection and step tracking with a defined sequence of tasks per new hire. BambooHR Onboarding is a separate module with customizable task checklists, e-signature via electronic W-4, I-9, and direct deposit forms. Completed onboarding task histories do not migrate because the workflow engines are proprietary. We deliver a written inventory of active Checkwriters onboarding templates for the customer's admin to reconstruct in BambooHR Onboarding.
Checkwriters
Performance Reviews
BambooHR
Performance Management (Pro tier)
1:1Performance review records and templates in Checkwriters (an add-on module) are stored in a proprietary format tied to the review workflow engine and cannot be exported via documented API. We do not attempt automated migration of review content because it produces incomplete or corrupted records. We flag this gap upfront and recommend a parallel manual review process in BambooHR Pro, with review templates rebuilt as BambooHR review cycle templates post-migration.
Checkwriters
Benefits Administration
BambooHR
Benefits Tracking (add-on)
1:1Checkwriters benefit plan enrollments, carrier connections, and deduction elections map to BambooHR's Benefits Tracking module (an add-on to Core and Pro). We map active enrollments to destination plan equivalents, including carrier name, plan type (medical, dental, vision), coverage tier (employee, employee+spouse, family), and annual deduction amount. Open enrollment period data and qualifying life event elections require coordination with the customer's benefits admin to ensure correct plan-year alignment in BambooHR.

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 scope definition
We audit the Checkwriters tenant at HR Admin scope to enumerate employee records, custom field definitions, accrual policy types, active deduction and benefit enrollments, and any open payroll batch states. We coordinate with the customer's HR Admin to define the Report Writer export templates for historical payroll data (earnings register, deduction register, pay stub history). We confirm whether BambooHR Payroll is in scope and which benefits tracking module (if any) is active in the destination. The discovery output is a written migration scope with a record-count matrix and a decision checklist for payroll and benefits add-on activation.
BambooHR environment preparation
We provision or validate the BambooHR environment including the appropriate tier (Core, Pro, or with add-ons), configure time-off policy types to match the accrual carry-forward logic discovered in Checkwriters, and set up benefit plan records with carrier names and plan types. Custom fields discovered in Checkwriters are pre-created in BambooHR with matching field types (text, date, dropdown, numeric). If BambooHR Payroll is in scope, pay run configuration aligns with Checkwriters pay frequency and check-date-to-pay-date mapping.
Report Writer extraction and data validation
The customer's HR Admin runs the agreed Report Writer exports from Checkwriters (historical payroll, accrual balances, deduction histories, custom field values). We review the exported CSVs for completeness, flag any missing date ranges or blank fields, and request re-runs before the transform step begins. Check-date range logic is documented for every payroll item so that the translation to calendar effective dates is accurate. We do not begin transform until all source exports are validated.
Data transform and field mapping
We apply the check-date-to-calendar-date translation for all payroll rate and deduction items, compute accrual carry-forward balances for each employee based on the Checkwriters accrual policy type, and map deduction records to BambooHR deduction setup. Custom field values are mapped to the pre-created BambooHR custom fields by field name and type. Benefit enrollments are mapped to BambooHR benefit plans with coverage tier and annual deduction amounts preserved. Active onboarding workflows are documented as a written inventory rather than migrated.
Sandbox migration and reconciliation
We run a full migration into the customer's BambooHR sandbox environment using the validated source data. The customer's HR lead reconciles record counts (employees in, time-off balances in, deductions in, benefits in), spot-checks 20-40 random records against the Checkwriters source, and confirms accrual balances match pay stub references. Any field mapping corrections are documented and applied to the production migration plan. This step gates the production migration start.
Production migration and cutover
We run the production migration in dependency order: employees first (with custom fields), then time-off accruals and balances, then deductions and benefits, then document references. Historical payroll (if in scope) is imported last as pay stub document links. We freeze Checkwriters writes during cutover and run a final delta import of any records modified during the migration window. BambooHR becomes the system of record upon successful cutover validation. We deliver the onboarding workflow inventory and performance review gap assessment to the customer's admin team for manual rebuild.
