What the Assessment Covers
A useful assessment examines customization at both the technical and business-process levels. Reviewing only source code can miss dependencies between accounting workflows, security roles, reports, and third-party integrations.
- Custom code: Review Dexterity customizations, scripts, stored procedures, triggers, and other modifications.
- Forms and windows: Identify modified GP screens, fields, menus, and user-interface extensions.
- Reports: Inventory modified reports, financial statements, management reports, and reporting dependencies.
- Integrations: Document interfaces connecting GP with banking, payroll, CRM, procurement, tax, warehouse, or other systems.
- Workflows and security: Examine approval paths, user roles, permissions, and process-specific configurations.
The assessment should also document ownership, business purpose, frequency of use, and the users or departments affected by each customization.
How Dynamics GP Customizations Are Evaluated
Each customization should be classified according to its business value, technical dependency, compatibility requirements, and relevance to the target GP environment. A practical assessment separates essential customizations from those that can be simplified or replaced by standard capabilities.
For example, a customized accounts payable approval process may be critical because it controls authorization before posting. A specialized report may be less central if equivalent information can be produced through standard GP reporting or an existing analytics platform.
Customization Design provides a useful way to evaluate how business requirements translate into technical changes, particularly when the upgrade is also an opportunity to standardize finance workflows.
A structured Customization Checklist Finance can then capture affected modules, owners, dependencies, testing requirements, security considerations, and required documentation for each customization.
ERP Integration and Upgrade Dependencies
Dynamics GP customizations frequently interact with external systems, so the assessment should trace data movement rather than treating GP as an isolated application. This includes inbound transactions, outbound records, master data synchronization, and reporting feeds.
When reviewing an integration architecture, Keep Your GL Codes Aligned in Any ERP System is especially relevant because changes to account structures or mapping logic can affect financial reporting during an ERP migration or upgrade.
The chart of accounts should also be examined carefully. What Drives COA Differences in ERP Platforms? helps frame why account structures can vary between ERP environments and why mapping decisions matter when extending or upgrading Dynamics GP.
Organizations evaluating hosting or infrastructure changes can also use Cloud vs On-Premise ERP: Key Differences (2026) to compare the implications of the target ERP architecture alongside customization requirements.

Automation and Customization Assessment
An upgrade assessment can also identify finance activities that are suitable for standardized automation after the GP environment has been reviewed. The Hyperbots Platform supports finance automation while allowing company-specific workflows, ERP integrations, roles, and GL structures to reflect established operating requirements.
Process Specific Capabilities can support process-focused finance automation where reconciliation, invoice handling, or other workflows require domain-specific rules and data. Ready to Deploy Capabilities can provide pre-trained agents and ERP connectors when an organization wants to extend finance workflows using established capabilities.
For workflows that improve through user feedback, Self Learning Capabilities can help refine processes and GL coding based on human actions. A Human in the Loop approach can preserve appropriate review and approval points while automation handles repeatable finance activities.
Assessment Deliverables and Upgrade Testing
A completed assessment should produce a practical customization register rather than simply a technical inventory. Each record should identify the customization, business purpose, affected GP module, dependencies, owner, target-state treatment, and validation requirements.
- Retain: Keep the customization when it remains essential and compatible with the target environment.
- Redesign: Rework the customization when the business requirement remains but the technical implementation should change.
- Replace: Use standard GP functionality or a supported extension when it satisfies the requirement.
- Retire: Remove obsolete customizations that no longer support an active business process.
Upgrade Testing should then validate the selected target-state customizations through representative transactions, reports, integrations, workflows, and security scenarios. Testing should include finance-critical activities such as posting, purchasing, receivables, payables, bank processing, period closing, and financial reporting.
Best Practices for a Reliable Assessment
Begin with an accurate baseline of the existing Dynamics GP environment before making design decisions. Combine technical discovery with interviews involving accounting, finance operations, IT, and process owners so that the assessment reflects how the system is actually used.
Maintain clear traceability between each current customization and its target-state decision. This makes it easier to plan development, testing, user acceptance, training, and deployment activities.
Where finance teams use automation alongside GP, integrations should be evaluated for data synchronization, transaction ownership, master-data mapping, and timing. This ensures that upgraded workflows continue to operate against appropriate ERP data.
Organizations can also evaluate technology-led finance transformation alongside customization decisions. The assessment should distinguish between preserving a required GP capability and extending the finance function with modern AI-supported workflows.
Summary
Dynamics GP Upgrade Customization Assessment provides a structured method for understanding how existing customizations affect an upgrade and deciding what the future-state environment should contain. By reviewing code, forms, reports, integrations, workflows, security, and business requirements together, organizations can create a controlled upgrade plan that protects financial reporting and operational continuity.
The strongest assessments connect every customization to a documented business purpose, target-state decision, and testing requirement. This creates a clearer foundation for upgrading Dynamics GP while improving finance processes and maintaining reliable financial performance.
