Overview

What this migration involves

Aderant Expert Sierra is a legal practice management ERP designed for mid-to-large law firms — it houses clients, matters, time entries, billing records, and trust accounts in a tightly integrated financial system. Freshsales is a cloud CRM built for sales and pipeline management, with a data model centered on Leads, Contacts, Accounts, and Deals. These platforms serve entirely different audiences, and the migration is primarily driven by firms that want to separate their front-office CRM from their back-office legal billing — or firms leaving legal software altogether and adopting Freshsales as their primary client-management tool. FlitStack AI maps Aderant's Client and Matter records into Freshsales Accounts and Deals, preserving matter numbers and practice-area taxonomy as custom fields. Contact records migrate into Freshsales Contacts, with a routing split: contacts associated with active matters become Contacts, while unconverted or dormant client contacts route to Leads. Time entries and billing history present a structural challenge — Aderant stores these as financial line items that have no native equivalent in Freshsales; we export them as custom-field data or reference records and flag them for post-migration reconciliation. The migration runs against Freshsales via its REST API, using scoped read access on Aderant so your team continues working during the cutover window. Workflows, trust accounting logic, and billing automation do not migrate — they must be rebuilt or retained in Aderant for financial compliance.

Why teams make this switch

Two sides of the same decision

Leaving

Aderant Expert Sierra logo

Aderant Expert Sierra

What's pushing teams away

  • Implementation complexity and cost are significant deterrents — firms report months-long projects and substantial consulting fees, making Expert Sierra impractical for smaller or budget-constrained practices.
  • The user interface is widely described as dated and non-intuitive, creating steep onboarding curves and lower adoption rates among administrative staff and timekeepers outside the core legal team.
  • Limited modern mobility and collaboration features compared to newer cloud-native competitors, leaving firms that prioritise client portals and mobile-first workflows feeling underserved.
  • Competitors including Clio Manage and Filevine offer faster deployment timelines and lower total cost of ownership for firms that do not require the full depth of Expert Sierra's financial module.

Choosing

Freshsales logo

Freshsales

What's pulling them in

  • Lowest barrier to entry among major CRMs — the free tier supports up to 3 users and includes core CRM functionality before committing to per-seat pricing.
  • Built-in chat, email, and phone reduce reliance on third-party integrations for basic sales communication and contact management.
  • Freddy AI contact scoring and deal insights are included on Pro plans at a lower price than comparable HubSpot tiers.
  • Kanban pipeline views across Contacts, Accounts, and Deals provide visual deal management without requiring custom configuration.
  • Integration with the broader Freshworks ecosystem (Freshdesk, Freshchat, Freshservice) reduces tool sprawl for teams already using Freshworks.

Object mapping

How Aderant Expert Sierra objects map to Freshsales

Each row shows how a Aderant Expert Sierra object lands in Freshsales, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

Aderant Expert Sierra

Client

maps to

Freshsales

Account

1:1
Fully supported

Aderant Client records map directly to Freshsales Accounts. The client name becomes the Account Name, and the primary billing address maps to the Account's address fields. Client status (active/inactive) is preserved as a custom pick-list field on the Freshsales Account so inactive clients can be flagged without being deleted.

Aderant Expert Sierra

Matter

maps to

Freshsales

Deal

1:1
Fully supported

Aderant Matter records map to Freshsales Deals. The matter number maps to a custom field (Matter_Number__c) on the Deal, and the matter description maps to the Deal's description field. Practice area maps to a custom pick-list field (Practice_Area__c) so deal records retain their legal domain classification in Freshsales.

Aderant Expert Sierra

Matter:Client association

maps to

Freshsales

Deal:Account association

1:1
Fully supported

The one-to-many relationship between Aderant Client and Matter translates to Freshsales Deal linked to an Account by the account_id foreign key. Each matter lands as a separate Deal associated with its parent Client Account, preserving the firm-level view of client activity in the Account record.

Aderant Expert Sierra

Client Contact (active matter)

maps to

Freshsales

Contact

1:1
Fully supported

Aderant contacts associated with active matters are imported as Freshsales Contacts and linked to their corresponding Account. The contact's role on the matter (Attorney, Paralegal, Client) maps to Freshsales Contact's job_title field and a custom Role_on_Matter__c field. Original create dates are preserved as a custom datetime field.

Aderant Expert Sierra

Client Contact (no active matter)

maps to

Freshsales

Lead

1:many
Fully supported

Aderant client contacts that have no currently active matter split into Freshsales Leads rather than Contacts — this preserves them in the firm's prospect pipeline without conflating them with active client relationships. When a Lead converts later, Freshsales will create a Contact and Account from it.

Aderant Expert Sierra

Time Entry

maps to

Freshsales

Custom Object: Time_Entry__c

1:1
Fully supported

Aderant time entries have no direct Freshsales equivalent — Deals do not support line-item billing records. We create a Time_Entry__c custom object in Freshsales (Estate or Forest plan required for custom objects) linked to the Deal by a lookup relationship, with fields for date, hours, rate, description, and billing status.

Aderant Expert Sierra

Bill / Invoice

maps to

Freshsales

Custom Object: Billing_Record__c

1:1
Fully supported

Aderant bills and invoices are financial ledger records that do not map to any native Freshsales object. We create a Billing_Record__c custom object linked to the Account, storing invoice number, date, amount, status, and currency. The full financial ledger is preserved as an exported CSV kept alongside the Freshsales migration for audit purposes.

Aderant Expert Sierra

Document / File attachment

maps to

Freshsales

Freshsales File Attachments

1:1
Fully supported

Aderant document and file attachments on matters are downloaded and re-uploaded to Freshsales as file attachments on the corresponding Deal or Contact record. File size limits apply — Freshsales enforces a maximum file size per upload, which we manage by chunking large document sets.

Aderant Expert Sierra

Custom Field (user-defined on Matter)

maps to

Freshsales

Custom Field on Deal

1:1
Fully supported

Aderant user-defined fields on Matter records map to Freshsales custom fields on the Deal object. The field type is translated: text fields become Freshsales text fields, numeric fields become number fields, and pick-list fields become Freshsales dropdown fields. All custom fields require pre-creation in Freshsales before migration runs.

Aderant Expert Sierra

Trust / IOLTA Account

maps to

Freshsales

No equivalent

1:1
Fully supported

Aderant trust and IOLTA accounting records have no Freshsales equivalent and cannot be represented in a CRM. We export these records as a separate CSV financial file and flag them for retention in Aderant or a dedicated accounting system. This is a critical disclosure: Freshsales is not a financial or legal billing system and should not be used to store trust account data.

Aderant Expert Sierra

Rates / Billing Tier

maps to

Freshsales

Custom Field on Account

1:1
Fully supported

Aderant rate tables and billing tiers attached to clients are stored as custom pick-list fields on the Freshsales Account (Billing_Tier__c, Default_Rate__c). Individual matter rates can be stored on the Deal custom fields. These are reference data for the firm's pricing model — they do not drive billing in Freshsales.

Aderant Expert Sierra

Workflow / Automation rules

maps to

Freshsales

Not migrated

1:1
Fully supported

Aderant workflow rules governing matter intake, conflict checks, and billing automation have no equivalent in Freshsales. These are explicitly excluded from migration and must be documented separately. We provide a workflow audit export from Aderant so your team can reference it when rebuilding automation rules in Freshsales.

Pair-specific challenges

  • Practice-area taxonomy has no native home in Freshsales Deals

    Aderant classifies every matter by practice area (Litigation, Corporate, Family Law, etc.) as a core matter property. Freshsales Deals have no native practice-area field — the deal pipeline and stage model are designed for sales processes, not legal service lines. We map practice area to a custom pick-list field (Practice_Area__c) that your Freshsales admin must pre-create on the Deal object before migration. Without this field, the practice-area classification is lost, which breaks any downstream reporting that segments matters by legal domain.

  • Multi-currency billing requires manual currency normalization

    Aderant supports multi-currency client records — a single matter can carry invoices in USD, GBP, and EUR with real-time conversion to a base currency. Freshsales accounts store a single currency per record, and deal values are stored in that account's currency. When Aderant matters carry multiple currencies, we normalize all amounts to the client's primary currency during migration. Any currency mismatch between the normalized amount and the client's billing ledger must be reconciled post-migration against Aderant's exported financial file — Freshsales has no mechanism to represent multi-currency deals natively.

  • Trust and IOLTA accounting records cannot be represented in Freshsales

    Aderant's trust and IOLTA accounting module tracks client funds held in trust, with separate ledger entries for receipts, disbursements, and reconciliations. Freshsales has no trust accounting model — the platform has no concept of a client ledger, retainers, or trust disbursement rules. We explicitly exclude trust records from the CRM migration. These records must remain in Aderant or a dedicated legal accounting tool. Migrating them as custom objects into Freshsales would create inaccurate financial representations that violate bar association record-keeping standards.

  • Matter hierarchies and parent-matter relationships do not translate

    Aderant supports parent-matter structures where a single client engagement branches into sub-matters (e.g., a corporate transaction with multiple workstreams as child matters). Freshsales Deals are flat — there is no native parent-child deal hierarchy. We import each Aderant matter as a standalone Freshsales Deal, preserving the parent-matter reference as a custom text field (Parent_Matter_Number__c). Teams that relied on the hierarchy for billing aggregation or reporting will need to rebuild that logic using Freshsales' custom reporting or a BI tool.

  • Aderant's scoped API requires admin credentials for extraction

    Aderant's data extraction requires an administrator username and password — the migration cannot run with read-only API credentials. Your Aderant administrator must grant FlitStack AI scoped admin access during the migration window, and that access should be revoked immediately after the export completes. This is a security requirement from Aderant's API terms: third-party migration tools must use authenticated admin sessions, not API keys with limited scoping. The admin account needs read privileges on all objects being extracted, and FlitStack AI will provide a detailed list of required permissions before the migration window opens so your IT team can configure the appropriate role in Aderant's security settings.

Migration approach

Six steps for a successful Aderant Expert Sierra to Freshsales data migration

  1. Catalog Aderant data objects and define Freshsales custom field schema

    FlitStack AI connects to your Aderant environment using scoped admin credentials and exports a full inventory of Client, Matter, Contact, Time Entry, and Bill records. We generate a data dictionary identifying every user-defined field in use on matter records. From this inventory we produce a Freshsales setup plan: a list of custom fields to create, their types, and which Freshsales plan (Estate or Forest) is required to unlock the field count. Your Freshsales admin creates these fields before migration runs — this is the critical path step for timeline.

  2. Export Aderant records and run field-level mapping validation

    We export all Aderant records into a staging format and apply the field mapping defined in the plan. Before any data touches Freshsales, we run a mapping audit that flags value mismatches (e.g., currency normalization, status value translation, multi-currency normalization), contact-to-matter routing decisions (Contact vs. Lead), and any records that lack a required Freshsales foreign key (e.g., a Deal with no Account). The audit produces a correction report your team reviews before we proceed.

  3. Run a sample migration with reconciliation diff

    A representative sample — typically 200–500 records spanning clients, matters, contacts, and time entries — is migrated into Freshsales first. We generate a field-level diff comparing source values against destination values for every mapped field, so you can verify that matter numbers, practice areas, contact associations, and billing amounts landed correctly. Any mapping errors are corrected before the full migration run commits. Sample migration also validates that custom object (Time_Entry__c, Billing_Record__c) lookups resolve correctly.

  4. Execute full migration with delta-pickup window

    The full migration writes all validated records to Freshsales via the REST API, respecting Freshsales rate limits per your plan tier. After the initial load completes, a 24–48 hour delta-pickup window captures any records created or modified in Aderant during the cutover period. A final audit log records every record written, any failures, and the de-duplication decisions made. Trust account records and workflow definitions are exported as separate CSV and JSON files for your team's reference.

  5. Post-migration reconciliation and documentation handoff

    FlitStack AI delivers a reconciliation report comparing Aderant record counts against Freshsales record counts by object type. Any records that failed to migrate are listed with failure reasons. We also deliver the exported trust financial ledger and workflow audit file as separate deliverables. Freshsales workflows, billing automation, and matter intake rules must be rebuilt separately — we provide a workflow reference document exported from Aderant to guide that rebuild. One-click rollback is available within 72 hours of go-live if reconciliation uncovers systemic issues.

Most Aderant-to-Freshsales migrations complete within 48–72 hours of clock time for under 25,000 Aderant records. The longest planning step is pre-creating custom fields in Freshsales (Estate or Forest plan required for the field count needed for legal data). Migrations with over 200,000 records — particularly those that include time entry and billing history as exported custom objects — extend to 5–10 days. Trust accounting records are excluded from migration scope and delivered as a separate financial export.
