Overview
Bill4Time is a purpose-built time-tracking and legal-billing platform centered on Clients, Projects (matters), Time Entries, and Invoices, with support for LEDES billing codes, UTBMS litigation codes, and per-user billing rates (standard, overtime, double-time, and payable rates). HighLevel is an all-in-one CRM and marketing-automation platform built around Contacts, Companies, and Opportunities, with a custom-object model for extensibility and a workflow engine for automation. The data models diverge significantly: Bill4Time's matter-centric hierarchy has no native equivalent in HighLevel, and HighLevel's marketing-automation features (workflows, funnels, SMS sequences) have no Bill4Time counterpart. FlitStack AI reads Bill4Time data via its read-only REST API (v1 and v2 endpoints with OData query support), then writes into HighLevel using the HighLevel API's Contacts, Companies, Opportunities, and Custom Objects endpoints. We preserve original create dates, user assignments, and billing-rate hierarchies. Workflows, automations, and email templates do not migrate — we export definitions as JSON for your HighLevel admin to rebuild in the workflow builder.
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 Bill4Time object lands in HighLevel, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Bill4Time
Client
HighLevel
Contact + Company
many:1Bill4Time clients are both the billable entity and the organization. We split this into a HighLevel Contact (primary billing contact with name, email, phone) and a HighLevel Company (organization-level data: billing address, client type, account manager). The Bill4Time client ID is preserved as a custom field on both records for traceability.
Bill4Time
Project
HighLevel
Opportunity
1:1Bill4Time projects (matters) map to HighLevel Opportunities. The project name becomes the Opportunity name. Project status (Open/Closed) maps to HighLevel pipeline stage. Bill4Time's projectType field is preserved as a custom pick-list on the Opportunity. The billingMethod (Hourly/Flat Fee/Percentage) is stored as a custom field.
Bill4Time
Time Entry
HighLevel
Custom Object (TimeEntry)
1:1Time entries have no direct HighLevel equivalent — HighLevel does not have a native time-tracking object. We create a TimeEntry custom object in HighLevel with fields for entry date, billable hours, labor hours, activity type, billable amount, and rate type. Each TimeEntry record links to the parent Opportunity (project) and Contact (user).
Bill4Time
User
HighLevel
User / Contact
1:1Bill4Time users are team members who log time. We create a HighLevel User record for each Bill4Time user (matched by email) and also create a Contact record to serve as the user profile in HighLevel. User fields: fname, lname, email, userType, status, department, billingRate, overtimeRate, doubleRate, payableRate are mapped to custom fields on the Contact record.
Bill4Time
Invoice
HighLevel
Custom Object (Invoice)
1:1Bill4Time invoices carry laborAmount, expenseAmount, lateFeeAmount, paidStatus, invoiceDate, and invoiceTermType. HighLevel has no native invoice object. We create an Invoice custom object in HighLevel with these fields and link it to the parent Contact and Opportunity. The invoice PDF is downloaded and stored as a HighLevel File attachment.
Bill4Time
Expense
HighLevel
Custom Object (ExpenseEntry)
1:1Bill4Time expense entries track costs incurred against projects throughout engagement lifecycles. We create an ExpenseEntry custom object with fields for expense date, amount, category, description, billable status, and receipt attachment stored as a file reference. Each ExpenseEntry record links to the parent Opportunity representing the project and the Contact representing the client for proper data association.
Bill4Time
Custom Field (Client-level)
HighLevel
Custom Field on Contact
1:1Bill4Time Enterprise Add-On custom fields defined on client profiles, including text fields, number fields, date fields, list-based selections, client list selections, and user list selections, are parsed from the JSON customFields payload and created as equivalent HighLevel Contact custom fields. Each field type maps directly to its corresponding HighLevel field type to maintain data integrity throughout the migration process.
Bill4Time
Custom Field (Project-level)
HighLevel
Custom Field on Opportunity
1:1Bill4Time project-level custom fields defined in the project customFields JSON structure are read during migration and created as equivalent HighLevel Opportunity custom fields. HighLevel enforces a limit of up to 10 unique custom fields per custom object type and applies field uniqueness rules that must be respected during the schema creation phase.
Bill4Time
Billing Rate Hierarchy
HighLevel
Custom Number Fields on Contact
1:1Bill4Time's multi-level rate hierarchy (user rate → client rate → project rate → activity type rate → time entry rate) has no HighLevel equivalent. We store each applicable rate level as a separate custom number field on the Contact record: BillingRate__c, OvertimeRate__c, DoubleRate__c, PayableRate__c. The effective rate is resolved at migration time based on the hierarchy.
Bill4Time
LEDES / UTBMS Codes
HighLevel
Custom Pick-list Fields
1:1Bill4Time's LEDES billing export and UTBMS litigation codes are stored as text fields on time entries. We create HighLevel custom pick-list fields (LEDES_Code__c, UTBMS_Code__c, UTBMS_Code_Desc__c) on the TimeEntry custom object. Legal Enterprise Bill4Time accounts with LEDES billing land in the upper pricing tier.
Bill4Time
Attachment / File
HighLevel
HighLevel Files
1:1Bill4Time files attached to clients, projects, or invoices are downloaded and re-uploaded to HighLevel Files associated with the matching Contact, Opportunity, or custom object. File size limits are respected (HighLevel's 25MB per file cap). Inline images in notes are extracted and rehosted.
Bill4Time
Workflow / Automation
HighLevel
Not Migrated
1:1Bill4Time workflow templates for repeating tasks lack a direct HighLevel equivalent and cannot be automatically migrated due to architectural differences between the two platforms. We export complete Bill4Time workflow definitions as JSON reference files for your HighLevel administrator to review and reconstruct equivalent logic using HighLevel's workflow builder interface. This migration limitation is documented upfront so your team can plan accordingly.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Bill4Time gotchas
API is read-only with no write endpoints
Enterprise Add-On gates Custom Fields and unlimited imports
Invoice status divergence between reports and accounting page
HighLevel gotchas
Sub-account architecture creates isolated data silos per client
Usage-based telecom and AI costs are not in the subscription price
Workflows have no native equivalent in most destination CRMs
API rate limits cap bulk migration throughput at 100 requests per 10 seconds per sub-account
White-label configuration and branding assets do not export via API
Pair-specific challenges
Migration approach
Audit Bill4Time data via read-only API
FlitStack AI authenticates against the Bill4Time API using an API key from the Settings screen. We pull all clients, projects, time entries, users, invoices, and expense records using v2 endpoints where available, falling back to v1. We capture custom field definitions from the JSON customFields payload for both client and project objects. The audit produces a record count by object type, identifies custom fields, and surfaces any rate-hierarchy configurations. We flag accounts missing API keys and accounts on the free-trial tier (which may lack API access).
Create HighLevel custom-object schema
Before data is written, we create the TimeEntry and Invoice custom objects in HighLevel using the custom-object API. We define all custom fields (UTBMS codes, billing rates, rate types, paid status) as individual field definitions on the appropriate object. We also create the custom pick-list and number fields on Contacts and Opportunities. This step requires a HighLevel sub-account API token with permissions to create custom objects and fields. We deliver a schema setup checklist so your HighLevel admin can verify field types before data lands.
Resolve users and map owners by email
Bill4Time users are matched to HighLevel users by email address. Each user's billing rates (standard, overtime, double, payable) are written as custom number fields on the matched Contact record. Unmatched users are flagged before migration — your team either creates HighLevel user accounts first or assigns a fallback owner. Records that land without a resolved owner receive a designated migration owner to maintain data integrity. This step ensures every Bill4Time time entry and project has an assigned HighLevel user.
Run sample migration with field-level diff
A representative slice migrates first — typically 100–500 records spanning clients, projects, time entries, and invoices. We generate a field-level diff between the Bill4Time source record and the resulting HighLevel record for each object type. You verify that UTBMS code mapping, billing rate hierarchy resolution, and project-to-opportunity linking are correct before the full run. The sample migration also surfaces any HighLevel rate-limit responses that require pagination adjustments.
Full migration run with delta-pickup window
The full migration runs against HighLevel using batched API writes. A delta-pickup window (typically 24–48 hours) runs after the main migration to capture any Bill4Time records modified or created during the cutover window. All operations are logged to an audit log. If reconciliation fails, one-click rollback reverts the HighLevel sub-account to its pre-migration state. After rollback is confirmed, the migration can be re-run with corrected mapping logic.
