Overview
Constructor CRM combines sales CRM with built-in project management, which works well for construction and services firms but creates friction when sales process complexity grows beyond the project-work model. Freshsales is a dedicated sales CRM from the Freshworks family, with native AI-powered lead scoring, multi-pipeline management, territory management, and built-in communication tools (phone, chat, email) under one umbrella. The data models diverge most notably in how deals relate to tasks and projects: Constructor embeds task management inside deal records, while Freshsales treats sales activities as standalone objects linked to contacts and deals but not hierarchically nested. Constructor lifecycle stages map to Freshsales lifecycle stages as a custom pick-list field, since Freshsales has its own stage model that may not align one-to-one with Constructor's statuses. We migrate all standard objects (accounts, contacts, leads, deals, tasks, events, notes, files) via the Constructor and Freshsales REST APIs. Workflows, automation rules, and project hierarchies do not migrate and must be rebuilt in Freshsales using its workflow builder and sales sequences. A sample migration with field-level diff runs first, followed by the full cutover with a 24–48 hour delta-pickup window to capture any in-flight changes during the go-live period.
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 Constructor 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.
Constructor
Contact
Freshsales
Contact
1:1Constructor contacts map directly to Freshsales contacts. Email serves as the unique identifier for deduplication, so duplicate emails are merged or flagged. All standard contact properties—first name, last name, email, phone, job title, and address—migrate as direct field mappings. Custom fields on contacts are listed in pre‑migration plan and created in Freshsales before the run. Created and updated timestamps are preserved for audit continuity.
Constructor
Lead
Freshsales
Lead
1:1Constructor leads map to Freshsales leads. Lead status in Constructor maps to Freshsales lead status using a value-by-value mapping. Unconverted leads land in Freshsales as Lead records; leads that already converted in Constructor migrate as Contacts with a conversion flag preserved.
Constructor
Company
Freshsales
Account
1:1Constructor companies map to Freshsales accounts. Company name, domain (mapped to the website field), industry, employee count, and annual revenue migrate as direct fields. Constructor parent‑company hierarchies become Freshsales Parent Account lookups, requiring the parent account to be migrated first to resolve foreign keys. Custom fields on companies are listed in pre‑migration plan and created in Freshsales before migration. Created and updated timestamps are preserved for audit continuity.
Constructor
Deal
Freshsales
Deal
1:1Constructor deals migrate to Freshsales deals. Deal name, value, close date, owner, and stage migrate as direct or value‑mapped fields. Constructor deal pipelines map to Freshsales deal pipelines 1:1 basis, with stage names aligned per pipeline. Custom fields on deals are listed in pre‑migration plan and created in Freshsales before migration. Created and updated timestamps are preserved for audit continuity. Deal‑task links become Freshsales Task records linked to parent deal.
Constructor
Pipeline
Freshsales
Deal Pipeline
1:1Each Constructor pipeline becomes a Freshsales deal pipeline. Stage names and probabilities are mapped value‑by‑value, preserving the original ordering of stages within the pipeline. Constructor pipelines that use non‑standard stage labels require custom stage creation in Freshsales before the migration runs; we provide a stage‑creation worksheet listing each required stage and its probability. After the pipeline is configured, deals migrate using the mapped stages.
Constructor
Lifecycle Stage
Freshsales
Lifecycle Stage (custom field)
1:1Constructor lifecycle stage labels have no direct Freshsales equivalent. We create a custom pick-list field (Lifecycle_Stage__c) on the Contact and Lead objects in Freshsales and migrate Constructor stage values as pick-list options. Stages that don't match Freshsales' seven-stage model are preserved as-is in the custom field.
Constructor
Deal Task (activity-type)
Freshsales
Task
1:1Constructor tasks that represent sales activities (follow-up calls, proposal reviews, meeting prep) map to Freshsales tasks. Original timestamps, owners, and task subjects are preserved. The Freshsales API creates each migrated task as a standalone Task record linked to the parent deal.
Constructor
Deal Task (deliverable-type)
Freshsales
Custom Field on Deal
1:manyConstructor tasks that represent deliverables or milestones (e.g., signed contract, permit received) may not fit Freshsales' activity model. These split: simple yes/no milestones become custom checkbox fields on the Freshsales Deal; richer task data migrates as a custom text field for audit reference. Your team decides the split policy before migration runs.
Constructor
Note
Freshsales
Note
1:1Constructor notes migrate to Freshsales notes. Original created and updated timestamps, owner, and note body text are preserved. Rich‑text formatting such as bold, italic, and bullet lists is retained where the source format is compatible with Freshsales' note editor. If a note is linked to a deal or contact in Constructor, the migrated note maintains the same association in Freshsales via the appropriate lookup field.
Constructor
Attachment / File
Freshsales
File
1:1Files attached to Constructor records—deals, contacts, companies—are downloaded and re‑uploaded to Freshsales Files, preserving the original file name and size. Freshsales enforces a 25 MB per‑file limit on Growth and Pro plans; files exceeding this threshold are split or linked. Inline images embedded in notes are extracted, re‑hosted as separate file records, and note is updated with new image URLs. Duplicate file names are handled via versioning to avoid data loss.
Constructor
Owner
Freshsales
User
1:1Constructor owner IDs are resolved by email match against Freshsales users. Owners with no matching Freshsales user are flagged before migration; your team either creates the Freshsales user first or assigns records to a fallback owner. No record lands without a valid Freshsales owner.
Constructor
Custom Field
Freshsales
Custom Field
1:1Constructor custom fields (on contacts, companies, deals) migrate to Freshsales custom fields of the corresponding type. Freshsales custom fields must be created before the migration runs; we deliver a custom field creation plan with correct Freshsales field types (text, number, pick-list, date, checkbox, etc.).

Constructor gotchas
Reporting and filter limitations make pre-migration data inventory harder
Estimating templates and take-offs carry business logic, not just data
KeyPay payroll data lives in a connected but separate system
Uptime variability requires staged migration windows
Custom integrations (Salesforce, ClickHomes, OCR, ELO) need separate scoping
Freshsales gotchas
Freddy AI is Pro-tier only despite heavy marketing

Migration approach
Discovery call and source audit
We connect to your Constructor account via API using read-only credentials and audit the full record inventory: contact count, company count, deal count, pipeline count, task sub-record distribution, custom field definitions, and lifecycle stage labels. We also check for data quality issues (duplicate emails, missing owners, malformed dates) and surface them before we write the migration plan. The audit output is a structured data map showing every Constructor object, field, and custom property alongside its Freshsales target.
Build Freshsales schema plan and custom field creation
Before data moves, we deliver a Freshsales schema setup plan: custom fields to create, pick-list values to add, Freshsales pipelines and stages to configure per Constructor pipeline, and a milestone-split policy worksheet for deliverable-type tasks. Your Freshsales admin (or our team acting as admin) creates the fields and pipelines. We validate the schema in a test Freshsales environment before committing to the full migration run. This step is the longest planning phase for teams with multiple Constructor pipelines or many custom properties.
Sample migration with field-level diff
A representative slice of records (typically 100–500) spanning contacts, accounts, leads, deals, and tasks migrates first. We generate a field-level diff showing the source value and destination value for every mapped field so you can verify lifecycle stage mapping, deal-task conversion, owner resolution, and pipeline mapping before the full run. Any mapping errors are corrected in the plan, and a second sample pass runs if needed. No records are deleted or overwritten in Freshsales during this step — it is a read-through validation.
Full migration with delta-pickup window
The full dataset migrates using the validated field map. Accounts migrate first, then contacts and leads, then deals with their converted tasks, then notes and files. A delta-pickup window (typically 24–48 hours) runs after the initial bulk load, capturing any records created or modified in Constructor during the cutover. FlitStack AI maintains an audit log of every record written, with source system ID preserved for traceability. If reconciliation reveals unexpected gaps, one-click rollback reverts the Freshsales instance to its pre-migration state.
Post-migration reconciliation and export workflow definitions
We run a record-count reconciliation against the Constructor source (contacts vs. contacts, accounts vs. accounts, deals vs. deals, tasks vs. tasks) and deliver a discrepancy report with explanations for any non-1:1 mappings (e.g., Constructor deal-task sub-lists becoming Freshsales individual tasks). The Constructor workflow export document is delivered at this stage. Your Freshsales admin uses it to rebuild automation rules in the Freshsales workflow builder or to configure Freshsales sequences for sales follow-up sequences.
