Overview
Madison Resources is a staffing-industry back-office layer handling payroll processing, tax administration, invoicing, and payroll funding. It has no documented REST API; all data extraction requires coordination through Madison support to generate file exports on a negotiated schedule. We extract Workers, Assignments, Payroll Runs, Invoices, Tax compliance records, and SUTA tracking from Madison, then map them into BambooHR's Employee records, custom fields for staffing-specific data (assignment status, SUTA rates, bill and pay rates), and the BambooHR Payroll module. We do not migrate factor-fee schedules or payroll funding terms because those are contractual arrangements outside Madison's operational data. We flag assignment history, SUTA tracking records, and compliance document references as requiring post-migration manual review or custom field configuration in BambooHR.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Madison Resources 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.
Madison Resources
Worker
BambooHR
Employee
1:1Madison Workers map to BambooHR Employee records. We extract full name, SSN, pay rate, tax withholding elections, start and end dates, and direct deposit details. BambooHR's Employee API accepts these fields natively. SSN is stored in BambooHR's protected field and transmitted via the API over HTTPS. Active Workers migrate as active BambooHR employees; terminated workers migrate as inactive employees with termination date and final assignment status preserved.
Madison Resources
Assignment
BambooHR
Employee (Custom Fields)
lossyMadison Assignment records (linking a Worker to a client placement with bill rate and pay rate) have no direct BambooHR equivalent. We create custom fields on the BambooHR Employee record: assignment_client_name__c, assignment_start_date__c, assignment_end_date__c, assignment_bill_rate__c, assignment_pay_rate__c, and assignment_status__c. For firms with hundreds of concurrent assignments, we recommend evaluating a staffing-specific ATS (TempWorks, Bullhorn, or Salesforces FSC) as the system of record for assignments post-migration; BambooHR is not designed to replace a staffing CRM.
Madison Resources
Payroll Run
BambooHR
BambooHR Payroll (Pay Period)
lossyMadison Payroll Runs (earnings, deductions, taxes, net pay per worker per pay period) do not map directly into BambooHR's payroll product, which is a separate add-on priced per employee per month. We transform payroll run data into BambooHR custom fields on each Employee record (last_gross_pay__c, last_net_pay__c, ytd_gross__c) and flag the customer to configure BambooHR Payroll separately for future runs. Historical pay stubs migrate as document attachments to each Employee File where BambooHR's file attachment API supports PDF imports.
Madison Resources
Invoice
BambooHR
BambooHR Custom Fields or Notes
1:1Madison Invoices (hours worked, bill rate, markups, status) are billing records that have no native equivalent in BambooHR's HRIS data model. We map invoice header fields (client name, invoice amount, invoice date, status) to a BambooHR custom object or, for smaller invoice volumes, to a structured note on the related Employee record. Assignment-linked line items cannot be natively modeled in BambooHR. Firms that require invoice record retention should export Madison invoices to a document archive rather than relying on BambooHR for billing history.
Madison Resources
Tax Record
BambooHR
BambooHR Payroll (Tax Configuration)
lossyMadison Tax Records (quarterly and annual federal, state, and local withholding summaries) require transformation to align with BambooHR's payroll tax configuration. We map Madison's annual W-2 summary data to the Employee record for the applicable tax year, but BambooHR's tax filing and withholding tables must be configured in the payroll module by the customer's admin using current-year state and federal rates. Historical tax data migrates as read-only records; the active payroll tax configuration is set up post-migration.
Madison Resources
SUTA Tracking Record
BambooHR
Employee (Custom Fields)
lossyMadison's SUTA limit tracking records identify workers approaching state unemployment wage bases across multiple states. BambooHR has no native SUTA tracking object. We migrate limit data to custom fields: suta_state__c, suta_wage_base__c, suta_rate__c, and suta_ytd_taxable_wages__c on the Employee record. The customer should review current-year state rates in BambooHR's payroll tax tables post-migration; we flag historical SUTA data as audited records for compliance review rather than live tax calculations.
Madison Resources
Compliance Document
BambooHR
Employee File
1:1Madison stores I-9s, W-4s, and state-specific compliance paperwork. We extract document file path references and metadata and attach them to the corresponding BambooHR Employee File. BambooHR's file attachment API supports PDF and common document formats. The actual physical file transfer from Madison's document management layer is a separate coordination step requiring Madison support; we include the file manifest in the export scope but do not transfer files directly.
Madison Resources
Factor Fee Schedule
BambooHR
N/A
1:1Madison's factor-fee arrangements (advance rates, factoring fees, recourse provisions) are contractual and not part of Madison's operational data export. These financial terms must be renegotiated directly with the staffing firm's new funder or bank and are outside the scope of the data migration. We explicitly flag this gap in the scope document and recommend the customer involve their finance or lending team in parallel with the data migration.
Madison Resources
Worker (Historical)
BambooHR
Employee (Inactive)
1:1Terminated workers with completed assignment histories migrate to BambooHR as inactive employee records. We preserve SSN, hire date, termination date, final pay rate, and assignment status for compliance and historical reporting. If the customer does not require retention of inactive worker records, this step can be scoped out to reduce migration volume.
Madison Resources
Owner / Account Manager
BambooHR
Employee (Metadata)
1:1Madison payroll processors and account managers referenced in worker and assignment records are mapped to BambooHR employee records by email match where possible. Madison owner records typically do not correspond to BambooHR system users unless the same individuals administer the HR platform. We flag unmatched owners in a reconciliation report for the customer to resolve manually.

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.
Madison Resources gotchas
No public API means export scoping requires Madison coordination
Payroll funding terms are contractual and not exported
Multi-state SUTA rates change annually and vary by state
Document file exports require separate file-level coordination
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 Madison export coordination
We audit the full Madison data scope: active and terminated Workers, Assignment records, Payroll Run archives, Invoice history, Tax compliance records, SUTA tracking data, and Compliance Document file paths. Simultaneously, we initiate the Madison export request through the customer's account representative to lock the snapshot date and confirm the export format (CSV, Excel, or fixed-width). Madison's export generation takes one to three weeks depending on their queue, which is the primary driver of the extended scoping timeline on this pair.
Data profiling and schema design for BambooHR
We profile the exported file structure and validate field coverage against the scope. We design the BambooHR Employee schema: standard fields for name, contact, and employment dates; custom fields for Assignment data (client, bill rate, pay rate, status, dates); custom fields for SUTA tracking (state, wage base, rate, YTD wages); and Employee File attachments for Compliance Documents. If the customer purchases BambooHR Payroll, we configure the tax filing setup in parallel. We deploy the schema to a BambooHR test account for mapping validation before production migration.
Madison file extraction and transformation
Madison generates and delivers the file export on the agreed snapshot date. We validate record counts against our discovery estimates, check for partial-period payroll runs (pay periods that span the snapshot date), and identify any fields that are null, malformed, or inconsistently formatted across the export. We transform the data into BambooHR-ready CSV format: one row per Employee with flat custom fields for assignment and SUTA data, separate CSV batches for inactive employees and compliance document manifests. Any Madison-specific codes (state abbreviations, assignment status enums) are normalized to BambooHR-compatible values.
Sandbox migration and reconciliation
We run a full migration into the customer's BambooHR environment using production-like data volume. The customer's HR lead reconciles record counts against Madison export totals, spot-checks 20-30 random employee records against the Madison source, and validates custom field values for a sample of active assignments. Any mapping corrections (wrong field, missing value, incorrect status code) are resolved in this phase before production migration begins.
Production migration and cutover
We run production migration in record-dependency order: active Employees first, then inactive Employees, then Assignment custom fields, SUTA tracking custom fields, Tax summary data as document attachments, and Compliance Document references. We run a post-import row-count reconciliation against Madison export totals and resolve any discrepancies before declaring cutover complete. We freeze Madison write access during the cutover window and run a final delta pass for any records modified during migration.
Delivery and staffing-specific handoff
We deliver the Migration Completion Report with record counts, reconciliation sign-off, and a data gap inventory for any records that could not be automatically migrated. The gap inventory includes: Madison's Factor Fee Schedule (contractual, outside data scope), SUTA tracking data as custom fields (requires BambooHR payroll tax table review for current-year accuracy), and document file transfer status. We do not rebuild automations, workflows, or payroll funding arrangements; those are separate engagements or admin tasks documented in the handoff report.
