Overview
Moving from Attio to Freshsales is a schema simplification migration. Attio's relational object model—where custom Objects, Relationship Attributes, and Lists define business entities—converges into Freshsales' standard Contacts, Accounts, and Deals schema with custom fields. We reconstruct the parent-child relationship chains that Attio's flat CSV exports discard, map custom Attio Objects to Freshsales custom fields or related records, and resolve People-to-Contact and Company-to-Account ownership links before inserting Deals. Attio's Lists (segmentation logic stored outside records) migrate as contact tags or account groupings in Freshsales. Workflows, Sequences, and automation credit consumption do not transfer; we deliver a written inventory of active Attio workflows for your team to rebuild in Freshsales' automation builder. Freshsales' built-in phone, email, chat, and Freddy AI are available from day one, reducing the integration dependencies that drive Attio's credit costs.
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 Attio 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.
Attio
People
Freshsales
Contact
1:1Attio People records map to Freshsales Contact. The email address field becomes the dedupe key during import. All custom attributes on the People object map to Freshsales custom Contact fields. Relationship links to Companies become Account lookups. Owner assignments from Attio resolve to Freshsales Users by email match. We preserve the full People record including any linked interaction timestamps as Contact activity timeline entries.
Attio
Company
Freshsales
Account
1:1Attio Companies map to Freshsales Accounts. The company domain becomes the Account Website field and the dedupe key. All custom Company attributes map to Freshsales custom Account fields. Parent-company relationships in Attio map to Freshsales Account hierarchy if configured. Companies must import before People so that AccountId is resolved for Contact inserts.
Attio
Deal
Freshsales
Deal
1:1Attio Deals map to Freshsales Deals. Deal status values map to Freshsales sales cycle stages (Qualification, Proposal, Negotiation, Closed Won, Closed Lost). Relationship links to Companies and People must be resolved before Deal import: the parent AccountId is required, and linked People become Deal contacts via the Deal Contact Roles object. Closed-Lost reason and Closed-Won reason from Attio custom fields migrate to Freshsales deal loss reason and deal notes.
Attio
Custom Object
Freshsales
Custom Fields or Related Records
lossyAttio custom objects (Subscriptions, Investors, Partnerships, Projects) do not have a direct Freshsales equivalent because Freshsales does not expose a custom object API. We evaluate each custom object during scoping: objects with a simple field set map to custom fields on the nearest standard object (Contact, Account, or Deal); objects with their own relationship attributes map to a related record pattern (e.g., a Subscription custom object linked to Account becomes a custom Deal or a Note with structured fields). If the destination plan does not support sufficient custom fields (Growth supports 35 custom fields per object), we recommend consolidation or a plan upgrade before migration.
Attio
List
Freshsales
Tags or Contact Group
lossyAttio Lists are workflow-context collections of record entries, not standalone records. We extract list memberships for each Contact and Account and write them as Freshsales Tags (flat label assignments) or Contact Group entries. List names become tag names with a list_ prefix to distinguish them from ad-hoc tags. If a List represents a segment with complex membership criteria (e.g., 'all Contacts with Deal value over $50k in the Enterprise segment'), we document the criteria as a Freshsales smart list or contact filter specification for the admin to configure post-migration.
Attio
Relationship Attribute
Freshsales
Lookup or Multi-Select Field
1:1Attio Relationship Attributes define cross-object links (e.g., which People are linked to a Deal, which Companies are linked to a Person). We resolve these as foreign-key lookups in Freshsales: Deal-to-Account as AccountId, Deal-to-Contact via Deal Contact Roles, and Account-to-Contact via the standard AccountId on Contact. Many-to-many links (multiple People linked to one Deal) use the junction object pattern. Without resolving these before import, Deals arrive orphaned from their Accounts and Contacts.
Attio
Note
Freshsales
Note
1:1Attio Notes attach to records as threads and are first-class API objects. We migrate Notes with timestamps, author attribution, and record associations preserved. Notes link to the parent Contact, Account, or Deal in Freshsales via the Notes widget on the record. Rich text content preserves formatting where the destination field type allows.
Attio
Task
Freshsales
Task
1:1Attio Tasks attach to records with assignee, due date, and status attributes. We migrate Tasks 1:1 with owner assignments preserved as User references in Freshsales. Task status values (open, completed, cancelled) map to Freshsales task status. Due date and priority transfer directly. Tasks linked to specific Deals or Contacts maintain their parent-record associations in Freshsales.

Migration approach
Discovery and relationship chain audit
We audit the Attio workspace via API: all standard objects (People, Companies, Deals), all custom objects, all Relationship Attributes, all List memberships, and all Notes and Tasks. We identify the relationship chains that CSV exports would flatten (Deal-to-Company, Deal-to-Person, Company-to-Person) and map them to Freshsales lookup fields. We count total custom fields per object and flag any that exceed Freshsales Growth plan limits (35 per object). The discovery output is a written migration scope with object-level mapping and a Freshsales plan recommendation based on custom field count and record volume.
Schema pre-creation in Freshsales
We create all custom fields in Freshsales before any data import: custom Contact fields for Attio People attributes, custom Account fields for Attio Company attributes, and custom Deal fields for Attio Deal attributes. For Attio custom objects, we configure either a set of custom fields on the nearest standard object or a structured Note template. We configure Deal Contact Roles for many-to-many person-to-deal links. Tags are pre-created in Freshsales for List memberships. Schema is validated in a Freshsales trial or sandbox before production migration begins.
Relationship chain reconstruction from Attio API
We query Attio's API to extract every Relationship Attribute record: which Deal links to which Company, which Deal links to which People, and which Company links to which People. We build a lookup table (email to Freshsales Contact ID, company domain to Freshsales Account ID) that we apply during every insert. Without this step, Deals import without AccountId and Contacts import without AccountId, breaking every standard CRM relationship. This step runs before any Freshsales insert and is validated against the source Attio API response before proceeding.
Sample migration and reconciliation
We run a test migration with a representative subset (typically 100-500 records per object type) into Freshsales. The customer reconciles record counts, spot-checks 20-30 records for field accuracy, and validates that Deals are linked to the correct Accounts and Contacts. We correct any field mapping errors, relationship resolution failures, or data truncation before running the full migration. This step prevents production data quality issues and is required before cutover.
Production migration in dependency order
We run production migration in record-dependency order: Accounts (from Attio Companies), Contacts (with AccountId resolved from the relationship chain table), Deals (with AccountId resolved and Contact Roles inserted for linked People), Notes and Tasks (linked to parent records), Custom object data (as custom fields or structured Notes), and Tags (from List memberships). Each phase emits a row-count reconciliation report before the next phase begins. Any records created in Attio during the migration window are captured in a delta pass before cutover.
Cutover, validation, and automation rebuild handoff
We freeze Attio writes during cutover, run a final delta migration, then enable Freshsales as the system of record. We deliver the Attio Workflow and Sequence inventory document to the customer's admin team, mapping each workflow trigger and action to a Freshsales workflow equivalent. We support a five-business-day hypercare window where we resolve any record linkage issues or field mapping gaps raised by the team. We do not rebuild Attio workflows or sequences in Freshsales inside the migration scope; that is a separate engagement or an internal admin task.
