Overview
Bilr is a legal billing and practice-management platform built for law firms, with clients, matters, time entries, invoices, and trust accounts as its core objects. HubSpot CRM is a sales-and-marketing platform with contacts, companies, deals, and custom objects. The two platforms share almost no native object equivalence — Bilr's matter structure has no direct HubSpot analogue, and HubSpot's lifecycle_stage and deal pipelines work differently than Bilr's billing workflow. We map Bilr clients to HubSpot contacts and companies, matters to deals with a custom matter-type property, time entries to tasks with billing metadata, and invoices to a custom object. Trust accounting fields that Bilr tracks separately migrate as custom fields on the contact or matter deal. Workflows and automation in Bilr — billing rules, matter workflows, timer automations — do not migrate; we export their definitions as a rebuild reference for HubSpot workflows or a connected billing tool. The migration runs against HubSpot's CRM API with a delta-pickup window capturing any Bilr changes during cutover.

Object mapping
Each row shows how a Bilr 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.
Bilr
Client
HubSpot
Contact + Company
many:1Bilr clients contain firm-level data (firm name, address, industry) and individual contact data (billing contact, attorney). We split these: firm details become a HubSpot Company record, and the primary billing/contact becomes a HubSpot Contact associated to that Company. Secondary contacts from Bilr migrate as additional Contact records linked to the same Company.
Bilr
Matter
HubSpot
Deal
1:1Bilr matters map to HubSpot deals. The matter name becomes the deal name, the matter number is stored as Source_Matter_Number__c, and the matter type (hourly, flat-fee, contingency) becomes a custom pick-list property on the deal. Each matter-type may map to a different HubSpot deal pipeline if the firm uses separate billing workflows per type.
Bilr
Time Entry
HubSpot
Task
1:1Bilr time entries are billable activity records with date, duration, description, rate, and amount. We map these to HubSpot Tasks with the original timestamps preserved. Billing rate and amount migrate as custom number fields on the task so the financial context is available in HubSpot reports even though HubSpot does not natively handle legal billing.
Bilr
Invoice
HubSpot
Custom Object: Legal Invoice
1:1Bilr invoices carry invoice number, date, amount, status, and line items. HubSpot has no native invoice object at the CRM tier, so we create a Legal_Invoice__c custom object with fields for invoice number, amount, status, and a lookup to the associated deal (matter). Invoice line items are stored as a multi-line text field or JSON blob on the invoice record.
Bilr
Trust Account / IOLTA
HubSpot
Custom Fields on Contact
1:1Bilr tracks trust account balances per client, including IOLTA account balances and pending disbursements. HubSpot has no trust accounting model. We preserve this data as custom number fields on the HubSpot contact: Trust_Balance__c and IOLTA_Balance__c. Firms using this data for billing decisions should connect HubSpot to a dedicated legal accounting tool post-migration.
Bilr
Expense Record
HubSpot
Custom Object: Expense + Task
1:manyBilr expense records have a cost component (what the firm paid) and a billing component (whether it can be passed to the client). We split these: the expense metadata becomes a Legal_Expense__c custom object linked to the matter deal, and any billable expenses with client-facing descriptions also generate a HubSpot Task for tracking the reimbursement workflow.
Bilr
User / Staff Member
HubSpot
User
1:1Bilr users (attorneys, paralegals, admins) are matched to HubSpot users by email address. The mapping preserves the user's role in Bilr as a custom pick-list property on the HubSpot user so reporting can filter by attorney or staff type. If a Bilr user has no HubSpot account, their records are assigned to a fallback owner flagged for admin review.
Bilr
Document / File Attachment
HubSpot
HubSpot Files
1:1Bilr file attachments on matters (contracts, correspondence, invoices) are downloaded and re-uploaded to HubSpot Files associated with the corresponding contact or deal record. File size limits apply — HubSpot caps files at 25MB. Larger documents are flagged for manual re-upload to HubSpot's file library.
Bilr
Notes
HubSpot
Notes
1:1Bilr notes on clients and matters migrate as HubSpot Notes. Original create timestamps and the author (Bilr user) are preserved in HubSpot's note metadata. Notes are associated to the corresponding contact or deal based on where they were recorded in Bilr.
Bilr
Billing Rule / Rate Table
HubSpot
No Equivalent
1:1Bilr billing rules and attorney rate tables define how time entries are priced per matter type or client. HubSpot has no native billing-rule engine. We export the rate table as a reference CSV for manual reconfiguration in HubSpot Workflows or a connected billing integration. This data does not migrate as live records.

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.
Bilr gotchas
No trust accounting support is a hard blocker for IOLTA firms
Limited workflow and template customization
Per-seat pricing model is migration-cost-sensitive
Export scope discovery is required before migration
HubSpot gotchas
Marketing Contacts billing model is migration-critical
Feature tier gating is not visible until onboarding
Mandatory onboarding fees inflate year-one cost
HubSpot CSV importer cannot migrate engagements or attachments
Custom objects require Enterprise and a pre-existing schema
Pair-specific challenges
Migration approach
Audit Bilr data export and define HubSpot custom object schema
FlitStack AI extracts a full Bilr data export covering clients, contacts, matters, time entries, invoices, trust account balances, and file attachments. We then create the HubSpot custom object schema — Legal_Invoice__c, Legal_Expense__c, and custom properties on Deal and Contact — based on the firm's matter types and billing fields. The schema plan is delivered as a setup checklist so the firm's HubSpot admin can create fields in the correct order before data validation begins.
Map and deduplicate Bilr clients into HubSpot contacts and companies
Bilr clients may contain both firm-level and individual contact data. We split each client record: organization details become a HubSpot Company, and the primary billing contact becomes a HubSpot Contact linked to that Company. We deduplicate by email during this step — if a Bilr contact email matches an existing HubSpot contact, we update rather than create. Secondary Bilr contacts for the same client become additional HubSpot Contacts with the same primary Company.
Migrate matters to HubSpot deals with matter-type and billing metadata
Bilr matters become HubSpot deals. We map matter name to deal name, matter number to Source_Matter_Number__c, and matter type to the Matter_Type__c custom pick-list. Billing rate migrates to Billing_Rate__c on the deal. Owner resolution matches the Bilr matter's assigned attorney to a HubSpot user by email. Matters with no matching HubSpot user are flagged for admin assignment before the full migration run.
Run a sample migration with field-level diff on 100–500 records
A representative slice of Bilr records — spanning clients, contacts, matters, time entries, and invoices — migrates to HubSpot first. We generate a field-level diff comparing Bilr source values against the resulting HubSpot records. The firm reviews the diff to confirm matter-type mapping, trust balance preservation, and invoice linkage to deals before the full run commits. Any field mapping adjustments are made before proceeding.
Execute full migration with delta-pickup window and audit log
The full Bilr dataset migrates to HubSpot: clients and contacts, then matters to deals, then time entries to tasks, then invoices to the Legal_Invoice__c custom object. A delta-pickup window of 24–48 hours captures any Bilr records created or modified during the cutover so HubSpot reflects the final Bilr state at go-live. FlitStack AI generates an audit log covering every record created, updated, or skipped, and one-click rollback is available if reconciliation identifies unexpected data gaps.
