Overview

What this migration involves

OneAdvanced Legal is a practice-management and case-management platform built for UK and Irish law firms, with strong time-capture, integrated billing, and compliance features baked into a single cloud-native stack. Salesforce Sales Cloud has no native legal-matter model — matters, bills, time entries, and client-money accounting have to be built from Account, Case, custom objects, and junction relationships. The migration carries OneAdvanced's clients, contacts, matters, time entries, bills, and document attachments into Salesforce's Account-Case-Contact framework, supplemented by custom objects for billable time and legal-specific properties. Workflows — including matter-opening checklists, bill-review approvals, and compliance alerts — do not migrate and must be rebuilt in Salesforce Flow or Process Builder. FlitStack sequences the migration so foreign keys resolve correctly: Accounts first, then Contacts, then Cases with the matter hierarchy, then time entries linked via a custom junction object. The delta-pickup window captures any new time entries or bill adjustments made in OneAdvanced during cutover so Salesforce reflects the final ledger state.

What's pushing teams away

  • Firms report that the platform is harder to exit than to enter, with export scoping and data extraction requiring significant internal effort to scope correctly.
  • Support access via the portal and telephone system has frustrated some users following platform changes, with reports of unreachable support teams during critical periods.
  • Custom workflows and bespoke process configurations built over years create migration complexity that requires detailed audit before any data move can proceed safely.

Choosing

Salesforce Sales Cloud logo

Salesforce Sales Cloud

What's pulling them in

  • The AppExchange marketplace with 5,000+ prebuilt apps gives enterprises integrations for nearly every business workflow without custom development.
  • Native Einstein AI for lead scoring, opportunity insights, and predictive forecasting adds intelligence without a separate platform purchase.
  • Territory management, multi-currency support, and advanced forecasting satisfy the needs of complex B2B sales organizations with structured revenue teams.
  • Slack, Tableau, and CPQ are deeply integrated into the core platform, keeping the sales stack unified for teams already in the Salesforce ecosystem.
  • Organizations with a large, established Salesforce implementation choose it because switching costs — integrations, custom code, trained admins — are prohibitive.

Object mapping

How OneAdvanced Legal objects map to Salesforce Sales Cloud

Each row shows how a OneAdvanced Legal object lands in Salesforce Sales Cloud, including any object-level transformations, lookup resolution, or schema-design dependencies.

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

OneAdvanced Legal

Client

maps to

Salesforce Sales Cloud

Account

1:1
Fully supported

OneAdvanced Clients map directly to Salesforce Accounts. The firm name maps to Account.Name, and the primary contact on the Account gets the client-side contact role. Multi-address clients collapse to one primary billing address; additional locations stored as custom address fields or Account Contact Relations.

OneAdvanced Legal

Contact

maps to

Salesforce Sales Cloud

Contact

1:1
Fully supported

OneAdvanced Contact records map directly to Salesforce Contacts in a one-to-one relationship. Since every Contact requires an AccountId in Salesforce, FlitStack first resolves each contact's parent Client record to the corresponding migrated Account using name matching. This resolution step ensures that AccountId is populated correctly before contacts are written to Salesforce. Any contacts where the parent Client cannot be matched to an existing Account are flagged in the unresolved-contacts report for manual review and resolution.

OneAdvanced Legal

Matter

maps to

Salesforce Sales Cloud

Case

1:1
Fully supported

OneAdvanced Matter is the central work unit; Salesforce Case is the closest standard object. FlitStack creates a Case for every Matter, sets a RecordType of 'Legal Matter', and populates Matter-specific custom fields (Matter_Type__c, Jurisdiction__c, Opposing_Party__c) from OneAdvanced properties. The Case.AccountId links to the client Account.

OneAdvanced Legal

Matter hierarchy (parent/child matters)

maps to

Salesforce Sales Cloud

Case parent lookup

1:1
Fully supported

OneAdvanced supports sub-matters (a litigation matter with linked advisory sub-matters). Salesforce Case has a ParentCaseId field that maps to this — the top-level matter migrates first, then child matters reference it via ParentCaseId. Circular parentage is flagged and resolved to the most senior matter.

OneAdvanced Legal

Bill

maps to

Salesforce Sales Cloud

Custom Invoice object (Invoice__c)

1:1
Fully supported

OneAdvanced Bills with line items, VAT treatment, and payment status have no Salesforce standard equivalent. FlitStack creates an Invoice__c custom object with a lookup to the Case (matter) and Account. Each line item becomes an Invoice_Line_Item__c record or is stored as a JSON body on the Invoice record depending on the line-item count.

OneAdvanced Legal

Time Entry

maps to

Salesforce Sales Cloud

Custom Time_Entry__c object

1:1
Fully supported

OneAdvanced time entries track hours, rate, narrative, WIP/billed status, and fee earner per matter. Salesforce has no standard billable-time object. FlitStack creates a Time_Entry__c custom object with a lookup to the Case (Matter__c) and the fee-earner as OwnerId. Billable_Flag__c, Rate__c, Hours__c, and Narrative__c carry the full entry data.

OneAdvanced Legal

Document / File

maps to

Salesforce Sales Cloud

Salesforce Files (ContentDocument / ContentVersion)

1:1
Fully supported

OneAdvanced documents attached to matters re-upload as Salesforce Files (ContentVersion uploaded to the Case or Account). File size limits apply — OneAdvanced documents exceeding 25 MB are split or linked externally. Metadata including original filename, upload date, and author is preserved as ContentVersion fields.

OneAdvanced Legal

Custom matter properties

maps to

Salesforce Sales Cloud

Custom fields on Case (Matter__c)

1:1
Fully supported

OneAdvanced matter-level custom properties — such as Case_Type__c, Practice_Area__c, Court__c, or Counsel__c — migrate as custom fields on the Case object in Salesforce. FlitStack creates each custom field with the appropriate type (pick-list, text, lookup) before the data migration run.

OneAdvanced Legal

Fee Earner / Staff

maps to

Salesforce Sales Cloud

User

1:1
Fully supported

OneAdvanced staff with time-capture permissions map to Salesforce Users by email address. FlitStack generates an unresolved-owner report before migration: any OneAdvanced staff whose email does not match an existing Salesforce User is flagged so the firm can create the Salesforce User or assign a fallback owner before the run commits.

OneAdvanced Legal

Workflow / Matter checklist

maps to

Salesforce Sales Cloud

No equivalent

1:1
Fully supported

OneAdvanced matter-opening checklists, bill-review approval chains, and compliance alert workflows rely on platform-specific configurations that have no equivalent in Salesforce's standard object model. These automated processes cannot be exported or migrated directly and must be reconstructed using Salesforce Flow, including Flow screens, decisions, and action elements. FlitStack exports every active OneAdvanced workflow definition as a structured reference document containing the workflow name, triggering conditions, approval stages, and associated field values, providing the firm's Salesforce administrator or implementation partner with a complete blueprint for rebuilding each process in Flow.

Pair-specific challenges

  • No native legal-matter object in Salesforce — every matter becomes a Case with custom fields

    OneAdvanced centres the data model on the Matter object; Salesforce has no direct equivalent. The closest standard object is Case, but it is designed for support-issue tracking, not legal work units. FlitStack migrates every Matter to a Case with RecordType = 'Legal Matter' and creates the custom fields (Practice_Area__c, Jurisdiction__c, Matter_Type__c) your firm needs before writing a single record. If your firm runs multiple practice areas, each should get its own Record Type so page layouts and pick-list values can vary per practice — this schema planning is the longest pre-migration step.

  • Client-money sub-accounts require a custom Trust accounting model in Salesforce

    OneAdvanced's SAR-compliant cashiering tracks client money balances per matter as a built-in feature. Salesforce has no standard trust-accounting construct — the platform cannot natively enforce that funds received on behalf of a client are held separately from operating funds. FlitStack creates a custom Trust_Account__c object with a running balance field, a link to the client Account, and a ledger of individual receipts and disbursements. The firm's finance team needs to validate this model against their Solicitors Regulation Authority obligations before the migration goes live.

  • Time-entry-to-matter links need a custom junction object to support split billing

    In OneAdvanced, a single time entry is always tied to one matter with one fee earner. If a barrister or consultant works across multiple matters on the same day, OneAdvanced creates multiple time entries. Salesforce's standard Task or Event object cannot model this cleanly — FlitStack creates a Time_Entry__c custom object with a Matter__c lookup. For entries that straddle two matters, a Time_Entry_Matter_Junction__c junction object links a single time entry to multiple Cases, and bill totals are distributed proportionally by the hours allocated to each matter.

  • Workflow definitions and matter-opening checklists do not migrate and must be rebuilt

    OneAdvanced matter-opening checklists, bill-review approval chains, and compliance alert rules are configured inside the platform and have no equivalent in Salesforce's standard schema. These automations cannot be extracted and replayed in Salesforce Flow automatically — they require a rebuild. FlitStack exports a structured JSON or spreadsheet export of every active OneAdvanced workflow definition so your Salesforce admin or implementation partner has a complete reference when building the Flow equivalents. This export is delivered before the data migration runs so the rebuild runs in parallel.

  • Salesforce API daily limit can throttle bulk migration for large time-entry volumes

    OneAdvanced firms with high time-entry density — litigation practices with hundreds of billable entries per week across dozens of matters — can accumulate millions of time-entry records. Salesforce enforces a 100,000 daily API request limit on Enterprise Edition, plus 1,000 additional requests per user license. FlitStack handles this by using Bulk API 2.0 for the initial load, which operates under separate batch limits (15,000 batches per day, 10,000 records per batch). Time-entry migration is throttled to avoid hitting the REST API concurrent request ceiling, and the run is spread across multiple days if needed — all logged in the audit trail.

Migration approach

Six steps for a successful OneAdvanced Legal to Salesforce Sales Cloud data migration

  1. Discover OneAdvanced schema and Salesforce target configuration

    FlitStack reads your OneAdvanced export or API payload to inventory every client, matter, time-entry, bill, and custom property. We simultaneously work with your Salesforce admin to confirm the Case RecordType plan, custom object creation (Time_Entry__c, Invoice__c, Trust_Account__c), and field-level validation rules that will apply to the incoming data. This step produces a signed-off migration plan and field-mapping spreadsheet before any data moves.

  2. Create Salesforce custom objects and fields

    FlitStack creates the custom objects and fields identified in the discovery step — Time_Entry__c with its Matter__c lookup, Invoice__c with payment-status and VAT fields, Trust_Account__c with balance tracking — inside your Salesforce sandbox first. We validate that each custom field's type matches the source data (currency fields for amounts, pick-lists for status values, date fields for timestamps) and that the page layouts include the new fields before the schema is pushed to production.

  3. Resolve fee-earner owners and validate user accounts

    Every time-entry, matter, and bill in OneAdvanced is owned by a fee earner. FlitStack resolves each fee earner's email address against your Salesforce User list. Any email that does not match an existing Salesforce User generates an unresolved-owner report — the firm either creates the Salesforce User before the migration or assigns a fallback owner. No data record lands in Salesforce without a valid OwnerId.

  4. Migrate accounts and contacts before matters before time entries

    Salesforce foreign-key constraints require Accounts to exist before Contacts (via AccountId) and Cases before time entries (via Matter__c lookup). FlitStack sequences the migration in dependency order: Clients → Accounts, then Contacts with AccountId resolution, then Matters → Cases with parent-matter chain resolved, then Time Entries with Case lookup, then Bills with Case and Account links, then document attachments as Salesforce Files. Any circular parent-matter references are flagged and resolved to the most senior matter in the chain before the run commits.

  5. Run a sample migration with field-level diff

    A representative slice — typically 200–500 records spanning clients, matters, time entries, and bills — migrates first into a Salesforce sandbox. FlitStack generates a field-level diff comparing source values against destination field values, plus a record-count reconciliation showing the count of records written per object versus the source total. Your team reviews the diff to confirm custom field mapping, pick-list value alignment, and owner resolution before the full production run is scheduled.

  6. Full migration run with delta-pickup window and audit log

    The full migration commits all records to production Salesforce. A delta-pickup window — typically 24–48 hours after the run completes — captures any time entries or bill adjustments made in OneAdvanced during the cutover. Every operation is logged in an audit trail with source record ID, destination record ID, field-level before/after values, and the operator who triggered the write. One-click rollback reverts all records written in the migration if reconciliation fails.

Source

Strengths

  • Single platform consolidates practice management, accounts, cashiering, and document management for UK and Irish law firms.
  • Microsoft Azure hosting with UK South/North redundancy and ISO 27001 certification satisfies common SRA compliance requirements.
  • Per-seat per-month pricing model provides predictable cost scaling for growing firms.
  • Managed migration and local UK-based support are included under the Customer for Life programme.

Weaknesses

  • Public API documentation is limited, making third-party migration tooling dependent on manual scoping and extraction.
  • Firms with long-standing custom workflows often carry non-standard process configurations that require significant pre-migration audit.
  • Support access has been reported as difficult to reach via the self-service portal, which can delay issue resolution during cutover.

Strengths

  • Largest enterprise app ecosystem in CRM with 5,000+ AppExchange integrations covering nearly every vertical workflow.
  • Native Einstein AI delivers lead scoring, opportunity insights, and predictive forecasting without a third-party layer.
  • Advanced territory management, multi-currency, and flexible forecasting satisfy complex B2B revenue structures.
  • Deep platform extensibility: Custom Objects, Apex, Flow, and the Metadata API allow full schema customization.
  • Well-documented REST API, Bulk API, and Composite API with published rate limits for programmatic migration.

Weaknesses

  • Pricing model is layered and opaque in practice: per-seat fees plus storage overages, add-on subscriptions, and annual uplifts compound to 30–40% above sticker price.
  • Workflow Rules and Process Builder are deprecated, forcing all orgs onto Salesforce Flow — a migration task that catches many teams by surprise.
  • Steep administrative complexity: meaningful configuration requires a dedicated Salesforce admin or consultant.
  • API rate limits are edition-gated (100k/day base for Enterprise) and easily exhausted by large historical imports without throttling.
  • Data export is exportable via Data Loader but preserving relationship integrity across 30+ objects requires careful ETL sequencing.

Most OneAdvanced-to-Salesforce migrations complete within 5–10 days of clock time for under 25,000 records. The longest planning step is designing the Case RecordType and custom object schema to hold time entries and bills. Firms with more than 200,000 records — particularly those with deep time-entry histories across hundreds of active matters — extend to 10–14 days because Salesforce Bulk API throughput for time-entry batches requires careful throttling. Schema setup for the custom Trust_Account__c object, if required by your firm's compliance obligations, adds 2–3 days of configuration and testing.
