Overview
Moving from Gauss Box ERP to Epicor ERP is a platform-tier migration for companies outgrowing a regional all-in-one business management suite and moving toward a manufacturing-first ERP with global partner support. Gauss Box stores financial, HR, and operational data across modular apps with organization-specific Custom Attribute Sets and no publicly documented bulk-export API, so we sequence extraction module-by-module and probe for REST endpoints per object. Epicor Kinetic receives master data through its DMT (Data Management Tool) using CSV templates built from the Gauss Box schema, with transactional history migrated as opening balances and attachment metadata rather than full journal entry replay. JOPPD payroll compliance fields require explicit EU field mapping in Epicor, and Custom Attribute Sets with organization-specific data types are transformed to Epicor Extended User Defined Fields with customer sign-off on data type handling. We do not migrate Gauss Box workflows, custom business rules, or dashboard widgets as these are platform-native and require rebuild in Epicor Kinetic.

Object mapping
Each row shows how a Gauss Box ERP object lands in Epicor Prophet 21, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Gauss Box ERP
Chart of Accounts
Epicor Prophet 21
GL Account (PartBrk, COA segments)
1:1Gauss Box stores account hierarchies within the accounting module. We map account codes and segment structures to Epicor Kinetic's Chart of Accounts, preserving inactive account flags and account types. JOPPD-specific accounts (payroll tax and contribution codes) require explicit mapping to Epicor's tax and deduction code tables. If Gauss Box uses multi-segment account codes (e.g., 4-4-2-2), we configure Epicor COA segment definitions before import.
Gauss Box ERP
Customers
Epicor Prophet 21
Customer
1:1Gauss Box Contacts module with customer type migrates to Epicor Customer records. The customer address, payment terms, and credit limits transfer directly. Custom Attribute Set fields on customer records become Epicor Extended UDFs with customer sign-off on data type mapping (date vs. datetime, single-select vs. free-text). Customer-specific pricing tiers from Gauss Box map to Epicor Customer Price Lists.
Gauss Box ERP
Vendors
Epicor Prophet 21
Vendor
1:1Gauss Box Contacts module with vendor type migrates to Epicor Vendor records. We preserve the vendor address, payment terms, W-9/tax registration fields, and any Custom Attribute Set values as Epicor Extended UDFs. Inactive vendor records are flagged during pre-migration audit and mapped to a Vendor Status of Inactive in Epicor rather than deleted.
Gauss Box ERP
Items and Products
Epicor Prophet 21
Part and Product Group
1:1Gauss Box Items map to Epicor Part records with SKU, unit of measure, and standard cost preserved. We flag duplicate SKUs and inconsistent naming conventions during pre-migration audit and resolve them against a customer-approved alias table. Gauss Box product categories map to Epicor Product Groups. If Gauss Box uses multiple units of measure (each, box, pallet), we configure Epicor's UOM class before Part import. Inventory balances at cutover date become Epicor PartBin initial quantities.
Gauss Box ERP
Work Orders
Epicor Prophet 21
Job and Labor
1:1Gauss Box Work Orders (planning through invoicing loop) map to Epicor Job records. We preserve Work Order status, line items, material requirements, and assignee data. Open Work Orders at cutover migrate as Epicor Jobs in the appropriate Job status (complete, in-process, or released). Historical Work Orders migrate as closed Job records with actual labor and material costs. Custom Attribute Set fields on Work Orders become Epicor JobOper and JobMtl Extended UDFs.
Gauss Box ERP
Projects and Tasks
Epicor Prophet 21
Project and Task (WBS)
1:1Gauss Box Projects with activity logs and subtask hierarchies map to Epicor Project Management WBS (Work Breakdown Structure) entries. Project timelines, assignees, and status transfer directly. Activity logs from Gauss Box migrate as Epicor Project Task comments with a historical flag. Epicor's Projects module supports both discrete Job linking and milestone billing; we configure the appropriate Project type during scoping based on whether the customer uses project-based billing or just project tracking.
Gauss Box ERP
Employees
Epicor Prophet 21
Employee
1:1Gauss Box Employee records (departments, branches, roles, room reservations, live status) map to Epicor Employee. Employment data including department assignments and branch locations transfer directly. Gauss Box role definitions are mapped to Epicor Security Groups during migration, though role semantics differ between platforms and may require manual adjustment for fine-grained permissions.
Gauss Box ERP
Payroll and Time Entries (JOPPD)
Epicor Prophet 21
Payroll (HCM) and Labor
1:1Gauss Box JOPPD compliance records and automatic payroll calculations map to Epicor HCM Payroll (or Epicor Payroll for Kinetic Cloud if the customer licenses it). JOPPD-specific fields (Croatian payroll tax codes, contribution rates, and submission fields) require explicit EU compliance mapping to Epicor's country-specific payroll configuration. We do not replay historical payroll journal entries; instead, we migrate opening balances (accrued vacation, tax withholdings) as Epicor Payroll initialization records. Time entries from Gauss Box Log In module migrate as Epicor Labor records linked to the relevant Job or Project.
Gauss Box ERP
Documents
Epicor Prophet 21
Attachment (Document Management)
1:1Gauss Box Documents (inbound, outbound, templated with custom statuses) migrate as Epicor Attachments and Electronic Document Management (EDM) records. Document binary files transfer separately from metadata. We map Gauss Box document statuses to Epicor Document Type classifications. Document templates are not migrated as templates; we deliver a list of template names and field positions for the customer to rebuild in Epicor.
Gauss Box ERP
Equipment and QR Codes
Epicor Prophet 21
Resource and Tool
1:1Gauss Box Equipment with QR code identifiers and warehouse locations maps to Epicor Resource (for equipment used in production) and Tool records. QR code identifiers transfer as Epicor Resource characteristics. Equipment assigned users and location data migrate as Resource Group assignments and warehouse Plant locations.
Gauss Box ERP
Custom Attribute Sets
Epicor Prophet 21
Extended User Defined Fields (UDFs)
lossyGauss Box Custom Attribute Sets create organization-specific custom fields across modules. We enumerate all custom attributes during scoping, classify them by data type (date, datetime, text, single-select, multi-select), and create corresponding Epicor Extended UDFs with validation rules before any data import. Multi-select attributes in Gauss Box map to Epicor Character01-10 or UDF list fields depending on the target Epicor version. Customer sign-off is required before loading data with transformed custom fields.
Gauss Box ERP
User Roles and Permissions
Epicor Prophet 21
Security Groups and Roles
1:1Gauss Box User roles control access levels across modules. We map role definitions to Epicor Kinetic Security Groups and Roles, but role semantics differ significantly between platforms. We deliver a written role mapping inventory with the customer's admin reviewing each permission mapping. Gauss Box role-based field access does not migrate and must be reconfigured in Epicor Kinetic's field-level security model.
Gauss Box ERP
Dashboard Widgets
Epicor Prophet 21
(not migrated)
1:1Gauss Box 50+ dashboard widgets are platform-specific visualization layers with no meaningful Epicor Kinetic equivalent. We do not migrate dashboard configurations. We deliver a written inventory of widget names, data sources, and filter logic for the customer's Epicor admin to reference when rebuilding dashboards in Epicor Kinetic's dashboard framework.
Gauss Box ERP
Log In (Work Logs and Attendance)
Epicor Prophet 21
Labor and Time and Expense
1:1Gauss Box Log In module tracks working hours via QR code terminals and stores attendance summaries. These migrate to Epicor Labor records linked to the relevant Job or Project. QR code check-in timestamps become Epicor Labor Punch records with clock-in and clock-out times. Attendance summaries migrate as Epicor Time and Expense records with a historical flag.

Migration approach
Discovery and module inventory
We audit the source Gauss Box instance across all active modules in scope: Chart of Accounts, Customers, Vendors, Items, Work Orders, Projects, Documents, Employees, Payroll (JOPPD), Log In, Equipment, and any Custom Attribute Sets. We count records per module, probe for API endpoints, and assess data quality (duplicate SKUs, inactive records, missing required fields). We pair this with an Epicor Kinetic edition and module review to confirm which Epicor modules are licensed and what DMT templates are available for each object type. The discovery output is a written migration scope with record counts, extraction method per module, and a DMT load sequence draft.
Schema design and Epicor Extended UDF configuration
We design the destination Epicor Kinetic schema before any data import. This includes configuring the Chart of Accounts segment definitions, UOM classes, Product Groups, Part sites, Customer payment terms, Vendor tax settings, and Employee organizational hierarchies. We create Epicor Extended UDFs for every Gauss Box Custom Attribute Set field with appropriate data types, validation rules, and table assignments (Part, Customer, Job, Project). Schema is deployed into a Sandbox org for validation before production migration begins. JOPPD-specific field mapping is documented as a separate payroll configuration checklist.
Data quality audit and cleansing
We run a pre-migration audit on extracted Gauss Box data to identify duplicate SKUs, inconsistent product naming, inactive customer and vendor records, and incomplete Employee records with missing required fields. We produce a cleansing report with customer-approved resolution rules (which duplicates to keep, which SKUs to retire, which inactive records to flag vs. delete). Historical transactions referencing deleted SKUs are mapped to a catch-all legacy item record. Data cleansing is a collaborative step requiring customer sign-off before transformation begins.
Sandbox migration and reconciliation
We run a full migration into the Epicor Kinetic Sandbox using production-like data volume. The customer's Epicor admin reconciles record counts across all modules (Accounts in, Parts in, Jobs in, Employees in), spot-checks 25-50 random records against the Gauss Box source, and validates Epicor Extended UDF values. DMT load sequencing is validated in Sandbox before production. Any mapping corrections, missing validation rules, or UDF data type issues are resolved here.
Production migration in dependency order
We run production migration in Epicor DMT dependency order: Company and COA configuration, Plant and Warehouse setup, UOM Classes, Product Groups, Vendors, Customers, Parts with UOMs and PartBin initial quantities, Bill of Materials, Jobs with JobMtl and JobOper, Projects with WBS phases, Employees with organizational assignments, Payroll initialization records, Labor entries, Attachments and Document Management records. Each phase emits a row-count reconciliation report. JOPPD payroll fields are loaded as part of the Employee and Payroll phases with EU compliance sign-off.
Cutover, validation, and admin rebuild handoff
We freeze Gauss Box writes during cutover, run a final delta migration of any records modified during the migration window, then enable Epicor ERP as the system of record. We deliver the Custom Attribute Set to Extended UDF mapping document, the DMT load sequence reference, the role mapping inventory, and the dashboard widget inventory to the customer's Epicor admin team for rebuild. We support a one-week hypercare window where we resolve any reconciliation issues raised by the customer's team. We do not rebuild Gauss Box workflows or custom business rules in Epicor; these are documented as a separate rebuild scope.
