Overview
Aderant Expert is a legal practice management system built around the Client-Matter billing model — it tracks clients, matters, time entries, expenses, and invoices as a tightly integrated billing ledger. HubSpot is a general-purpose CRM that models customers as Contacts and Companies, with Deals representing sales opportunities. The migration challenge is translating Aderant Expert's matter-centric billing data into HubSpot's deal-centric pipeline model while preserving the financial history that matters for client reporting. We extract Aderant Expert data via direct SQL Server database connection (Admin credentials required) and load it into HubSpot via the HubSpot API using the Contacts, Companies, Deals, and custom properties endpoints. Workflows, billing rules, and eBilling guidelines do not migrate — those are destination-side configuration that must be rebuilt in HubSpot's automation tools or documented for your admin team. The result is a HubSpot portal with your client base as Companies, matters as Deals with custom billing properties, and original time/expense data preserved as reference fields on each deal record.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Aderant Expert object lands in HubSpot, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Aderant Expert
Client
HubSpot
Company
1:1Aderant Expert Client maps directly to HubSpot Company. Client name becomes Company name. Client address fields map to HubSpot's address property group. Multiple Aderant Expert contacts per client collapse to HubSpot contacts associated with the single company. We also preserve the original client ID in a custom property (Original_Client_ID__c) for future reference and to support de-duplication if needed.
Aderant Expert
Contact (under Client)
HubSpot
Contact
1:1Aderant Expert Contact maps 1:1 to HubSpot Contact. Original contact IDs preserved in Source_System_ID__c for traceability. Multiple contacts per matter are associated to the same HubSpot Company via the company association. We also set the contact type (e.g., attorney, paralegal, client) as a custom pick-list property (Contact_Type__c) to maintain role information in HubSpot.
Aderant Expert
Matter
HubSpot
Deal
1:1Aderant Expert Matter becomes a HubSpot Deal. Matter name maps to Deal name. Matter number stored as a custom property (Matter_Number__c). Matter status (open/closed/pending) maps to HubSpot dealstage with a value-mapping between Aderant Expert status pick-list and HubSpot pipeline stages.
Aderant Expert
Time Entry
HubSpot
Custom properties on Deal
1:1Aderant Expert time entries are aggregated by matter and stored as custom number fields on the HubSpot Deal: Total_Hours__c, Total_Billable_Hours__c, Total_Non_Billable_Hours__c. Individual time entry records are not created as separate HubSpot objects — they roll up to the deal-level summary.
Aderant Expert
Bill / Invoice
HubSpot
Custom properties on Deal + Line Items
1:1Aderant Expert bills map to HubSpot deal amount with invoice line items as Deal Line Items where HubSpot Professional/Enterprise is available. Invoice number stored as Invoice_Number__c, invoice date as Invoice_Date__c, and total billed amount as a custom currency field. This mapping preserves the financial history while allowing you to use HubSpot's reporting tools to analyze billing trends across deals.
Aderant Expert
Expense Entry
HubSpot
Custom properties on Deal
1:1Expense entries aggregate to deal-level custom fields: Total_Expenses__c, Expense_Category__c. Individual expense records are summarized per matter and stored as reference data on the associated HubSpot Deal. This approach keeps the deal record clean while preserving the full expense detail for reconciliation and reporting purposes.
Aderant Expert
Document (under Matter)
HubSpot
HubSpot Files + association
1:1Documents stored under Aderant Expert matters are downloaded and re-uploaded to HubSpot Files. Each file is associated to the corresponding HubSpot Deal via file-to-record linking. Original document names preserved. File size limits (HubSpot default 25MB per file) enforced during migration.
Aderant Expert
Billing Guideline
HubSpot
No equivalent
1:1Aderant Expert eBilling guidelines (client-specific billing rules, rate restrictions, expense disallowances) are billing configuration with no HubSpot equivalent. We export these as a structured reference document for your finance team to configure in a separate billing or eBilling tool post-migration.
Aderant Expert
User / Attorney
HubSpot
Contact (owner reference)
1:1Aderant Expert users who are attorneys or timekeepers map to HubSpot Contact records with an Owner flag. Their email is used for HubSpot user matching. Users who do not have a HubSpot login are flagged for admin to create accounts before the migration runs.
Aderant Expert
Custom fields (matter-level)
HubSpot
Custom properties on Deal
1:1Aderant Expert custom fields defined at the matter level are translated to HubSpot custom properties on the Deal object. Field data types are mapped: text → string, number → number, date → datetime, pick-list → HubSpot pick-list with value-by-value mapping.

Pair-specific challenges
Migration approach
Establish SQL Server database connection and audit Aderant Expert schema
FlitStack connects to your Aderant Expert MS SQL Server database using Admin credentials. We run a schema audit to map all tables and fields including custom fields, matter relationships, and billing tables. This produces a data dictionary we share with you before mapping begins — your Aderant admin verifies field meanings and flags any sensitive data that should not migrate.
Delta-pickup cutover with audit log and rollback plan
Full migration runs against HubSpot via the API. A delta-pickup window (24–48 hours) captures any matters or contacts created or modified during the cutover. FlitStack maintains an audit log of every record created and updated. One-click rollback reverts HubSpot to its pre-migration state if reconciliation identifies unexpected data gaps. After the cutover, we perform a final validation pass to ensure all deals have the expected custom properties and that the pipeline stages are correctly set.
