Overview
OneSuite and Freshsales have different data models that require careful object mapping before migration. OneSuite unifies CRM, project management, and invoicing under a Client entity that holds both person and organization data; Freshsales separates Contacts, Accounts (Organizations), and Leads into distinct objects with explicit relationships. We resolve the OneSuite Client into a Freshsales Contact or Account based on whether the record holds person-level or organization-level data, and we preserve the Client-to-Project relationship using custom fields on the resulting Freshsales Deal. OneSuite has no documented bulk API, so we use its officially documented CSV and JSON import paths to extract data, chunking large files to avoid buffer truncation. Custom fields in OneSuite are flattened directly onto entities with their original slugs as property keys; we remap each to a Freshsales custom field and flag any missing destination fields for pre-creation before migration runs. Workflows, automations, and project templates do not migrate automatically; we deliver a written rebuild map for the customer's admin team.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a OneSuite 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.
OneSuite
Client
Freshsales
Contact or Account
lossyOneSuite Client holds both person-level and organization-level data in a single entity. We classify each record at migration time: Clients with a first_name and last_name map to Freshsales Contact; Clients with an organization name and no individual contact name map to Freshsales Account (Organization). We preserve the full contact detail set (email, phone, address, social links) and the OneSuite revenue and ICP status fields as Freshsales custom fields. Email address serves as the dedupe key on import.
OneSuite
Project
Freshsales
Deal (with custom fields)
1:manyOneSuite Projects do not have a direct Freshsales equivalent because Freshsales has no native project management object. We map Projects as Deals with custom fields for project metadata: project status, start and end dates, milestones, and the linked Client as the Deal's primary Contact lookup. This preserves the project context on the CRM record but requires manual rebuild of project-specific task structures in Freshsales Tasks or a separate project management tool post-migration.
OneSuite
Lead
Freshsales
Lead
1:1OneSuite Leads map directly to Freshsales Leads with stage name, source attribution, and scoring preserved as custom fields. We check for email duplicates against migrated Contacts during the import phase to prevent duplicate records in Freshsales. Any custom scoring rules defined in OneSuite are preserved as custom field values and noted in the automation rebuild handoff document for reconfiguration in Freshsales.
OneSuite
Invoice
Freshsales
Deal (financial fields)
lossyOneSuite Invoices contain line items, tax rates, payment status, and currency. We map standard invoice fields to Deal fields in Freshsales but flag records with multi-currency configurations or complex custom tax setups for manual reconciliation post-migration. Freshsales has no native invoicing object; invoice metadata is stored on the Deal for reference, and customers needing full invoice reproduction use a Freshsales-supported invoicing integration.
OneSuite
Document
Freshsales
Note
1:1OneSuite Documents attached to Clients or Projects migrate as Freshsales Notes with the document name and URL preserved. Binary file content does not transfer into Freshsales native file storage; we migrate metadata and URLs and the customer recreates document access post-migration or maintains the original OneSuite storage for reference.
OneSuite
Custom Field
Freshsales
Custom Field
lossyOneSuite custom fields are flattened directly onto entities with their original slug as the property key (e.g., clientTier on the Company record). We parse the API response, remap each slug to a Freshsales custom field name, and pre-create missing custom fields in the Freshsales instance before migration begins. If a destination field does not exist, we flag it during discovery for creation and hold any records containing that field value until the field is provisioned.
OneSuite
Member
Freshsales
User
1:1OneSuite Members (team users) assigned to Projects, Clients, and Invoices map to Freshsales User records by email match. Owner lookups on Contacts, Accounts, Deals, and Leads are resolved at migration time through the User mapping. Any Member without a matching Freshsales User email is held in a reconciliation queue for the customer's admin to provision before record import resumes.
OneSuite
Pipeline Stage
Freshsales
Deal Stage
lossyOneSuite Lead pipeline stages map to Freshsales Deal stages (since Leads migrate to the Freshsales Lead object and Projects map to Deals). Stage names and order are preserved; any stages with custom automation triggers or conditional scoring rules are flagged in the automation rebuild handoff document for manual reconfiguration in Freshsales Workflows.

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.
OneSuite gotchas
No documented bulk API forces CSV or JSON UI import for migrations
Storage tier caps apply to imported file content and attachments
API custom field flattening requires slug-aware remapping
Lead count capped on lower tiers may require plan upgrade before migration
Freshsales gotchas
Freddy AI is Pro-tier only despite heavy marketing
Post-migration emails and sequences are disabled
Bot session credits are a one-time 500-session allocation
Phone credits charged per minute with no cap
File storage limits scale with plan tier
Pair-specific challenges
Migration approach
Discovery and scope enumeration
We audit the source OneSuite account across plan tier, total Client count, Project count, Lead pipeline structure, Invoice volume and currency complexity, Member count, and custom field inventory. We pre-scan storage consumption to flag accounts approaching tier limits, enumerate the total Lead count against the plan cap, and identify any custom field slugs that require Freshsales custom field pre-provisioning. The discovery output is a written migration scope document with record counts per entity and a list of fields requiring destination-side configuration before migration runs.
Schema design and object mapping configuration
We design the destination Freshsales schema to accommodate the OneSuite data model. This includes creating custom fields on Contact, Account, Lead, and Deal objects to receive the remapped OneSuite custom field values. We configure Deal stages to map from the OneSuite Lead pipeline. For the Client-to-Project relationship, we define custom fields on the Deal object to store the project reference and create any necessary custom objects if the customer requires a formal project hierarchy. We deploy the schema to a Freshsales trial or sandbox environment first for validation.
Test migration in Freshsales sandbox or trial
We run a test migration using a representative sample of OneSuite data (typically 50-100 records per entity type) into a Freshsales trial account. This validates the custom field mappings, the slug remapping logic, the Client-to-Contact-or-Account split rule, and the Project-to-Deal custom field mapping. Any import errors, dropped values, or record truncation issues surface here. We reconcile record counts and spot-check mapped values against the source before committing to a production migration date.
Data extraction from OneSuite
We extract all records from OneSuite using the officially documented CSV and JSON import paths. We chunk large datasets into multiple files to avoid import buffer limits, sequence the extraction by entity dependency, and validate record counts at the source before initiating the Freshsales import. We also extract document metadata and URLs separately from binary content, which we flag for manual handling post-migration. All custom field slug names are captured in the extraction manifest for the remapping phase.
Data transformation and import into Freshsales
We transform extracted records using the configured object mapping: Clients split into Contacts and Accounts based on record type; Projects map to Deals with custom fields for project metadata; Leads map directly to Freshsales Leads with score and source preserved; Invoices map to Deals with financial fields retained. We remap every custom field slug to its Freshsales equivalent. Member emails are resolved against the Freshsales User table. We import in dependency order (Users, Accounts/Contacts, Leads, Deals, Notes) and emit row-count reconciliation reports at each phase.
Validation, cutover, and rebuild handoff
We validate the production migration by reconciling record counts against the source data across all entities. We spot-check a sample of migrated records against OneSuite for field-level accuracy. We deliver the migration report alongside a written rebuild inventory for any project structures, automations, and pipeline configurations that require manual recreation in Freshsales. We support a one-week hypercare window for reconciliation issues raised during initial team use. We do not rebuild workflows, sequences, or project task structures as part of the standard migration scope.
