Overview
Moving from Sellsation CRM to Salesforce Sales Cloud is a migration from a structured, guided-sales platform with no public API to the world's largest CRM ecosystem. Sellsation organizes sales around Customers, Contact Persons, and Sales Projects with a traffic-light system that flags neglected deals and contacts—context that we preserve as custom fields in Salesforce so the history of stagnation is available to the new admin team. The core technical challenge is Sellsation's absence of a documented API: we perform a full scoping call to enumerate every exportable field, validate record counts against UI exports, and use CSV-based extraction with batch chunking and deduplication. We migrate the full activity timeline (calls, appointments, notes, tasks) as Salesforce Tasks and Events via the Bulk API 2.0, preserving chronological ordering against parent Contact and Opportunity records. Multi-level campaign structures, custom reports, geo map heatmaps, and dashboard configurations do not migrate as code; we deliver all underlying data so the customer's Salesforce admin rebuilds them from complete source information. Salesforce subscription cost (typically $80-$330 per user per month depending on edition) sits outside the migration fee and remains the customer's recurring cost.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Sellsation CRM object lands in Salesforce Sales Cloud, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Sellsation CRM
Customer
Salesforce Sales Cloud
Account
1:1Sellsation Customers are the primary account-level records containing company information, linked to Contact Persons and Sales Projects. We map these 1:1 to Salesforce Account, preserving the Customer name as Account Name, any industry or classification fields as custom Account fields, and the Customer's internal Sellsation ID as a custom field sellsation_id__c for audit and reconciliation. Account is the parent record for all Contact imports.
Sellsation CRM
Contact Person
Salesforce Sales Cloud
Contact
1:1Sellsation Contact Persons are individual contacts linked to Customers with full activity history including calls, meetings, and notes. We map these 1:1 to Salesforce Contact, preserving the Customer link as AccountId lookup and the Sellsation internal ID as sellsation_id__c. Any Sellsation traffic-light status (green/yellow/red indicating neglect) is preserved as a custom field traffic_light_status__c so the Salesforce admin can prioritize outreach on neglected contacts after migration.
Sellsation CRM
Sales Project
Salesforce Sales Cloud
Opportunity
1:1Sellsation Sales Projects are the deal/opportunity records tracked through pipeline stages with automated potential analysis. We map these to Salesforce Opportunity, preserving the pipeline stage name as StageName, the deal value as Amount, and any Sellsation potential score as a custom field potential_score__c. The traffic-light stagnation flag from Sellsation migrates as a custom stagnation_days__c integer field so the new Salesforce admin can rebuild stagnation alerts in Salesforce Flow.
Sellsation CRM
Pipeline Stage
Salesforce Sales Cloud
Opportunity Stage
lossySellsation's guided pipeline stages map to Salesforce Opportunity Stage values. We enumerate all Sellsation stage names during scoping, create matching Salesforce stage values with probability percentages, and configure a Salesforce Sales Process that scopes the stage whitelist per pipeline. If the customer uses multiple Sellsation pipelines, we create Salesforce Record Types to separate stage sets.
Sellsation CRM
Activity
Salesforce Sales Cloud
Task and Event
1:1Sellsation Activities (calls, appointments, notes, tasks attached to Contact Persons or Sales Projects) map to Salesforce Task and Event objects. We distinguish by Sellsation activity type: calls map to Task with TaskSubtype=Call, appointments map to Event with StartDateTime/EndDateTime preserved, notes map to Salesforce Note linked via ContentDocumentLink, and tasks map to Task with Status, Priority, and ActivityDate. We use the Bulk API 2.0 with time-bounded chunking because Sellsation teams with years of history can have activity counts 10-20x their contact count.
Sellsation CRM
Campaign
Salesforce Sales Cloud
Campaign
1:1Sellsation multi-level campaigns (combining emails, letters, conditional stage movements, and automated task creation) map to Salesforce Campaign records, but the automation logic does not migrate. We export campaign structure (name, type, status, start and end dates, budgeted cost) and campaign member enrollment data. The conditional stage movement logic and automated task creation rules are documented in the handoff inventory for rebuild in Salesforce Flow.
Sellsation CRM
Task
Salesforce Sales Cloud
Task
1:1Sellsation Tasks assigned to users with due dates, linked to Contact Persons or Sales Projects, map directly to Salesforce Task. Task status, assignment (OwnerId via email match to Salesforce User), priority, and due date migrate. Sellsation task linking to Contact or Sales Project is preserved via the WhatId lookup pointing to the migrated Contact or Opportunity.
Sellsation CRM
Appointment
Salesforce Sales Cloud
Event
1:1Sellsation Calendar appointments with date, time, duration, and attendee lists attached to Contact Persons map to Salesforce Event. StartDateTime, EndDateTime, Subject, Location, and DurationInMinutes migrate. Attendee lists map to Salesforce EventRelation records pointing to the migrated Contact and User records. Any appointment notes migrate as Event Description.
Sellsation CRM
Custom Fields
Salesforce Sales Cloud
Custom Fields
1:1Sellsation supports custom fields on primary objects (Customers, Contact Persons, Sales Projects, Activities). We enumerate all custom fields during scoping, map them to Salesforce custom property schemas on the corresponding standard or custom objects, and flag any with picklist or formula dependencies for the customer admin to resolve before migration. Custom field API names are preserved with __c suffix per Salesforce standard. Picklist value mismatches require a mapping table during transform.
Sellsation CRM
Geo Map Data
Salesforce Sales Cloud
Address and Geolocation Fields
1:1Sellsation territory and heatmap data is stored as internal map state rather than standard geographic coordinates. We export the linked Sales Project location data as standard address fields (Street, City, State, PostalCode, Country) and a custom geolocation field (latitude/longitude via custom number fields) so the geographic context is available for Salesforce territory management, MapAnything, or GeoPointe. The native heatmap visualization does not migrate.
Sellsation CRM
KPIs and Reports
Salesforce Sales Cloud
Data Export for Report Rebuild
lossySellsation KPIs and custom reports store platform-native configurations with no export mechanism. We export all underlying data—Sales Projects with pipeline metrics, activity counts, deal values, stage durations—so the customer's Salesforce admin rebuilds reports from complete source data. The KPI dashboard layout and custom report definitions are documented in the handoff inventory with recommended Salesforce Report Type and Dashboard equivalents.
Sellsation CRM
Owner/User
Salesforce Sales Cloud
User
1:1Sellsation users assigned to Contacts, Companies, Sales Projects, Activities, and Tasks map to Salesforce User by email address match. We extract every distinct Sellsation user referenced in the export, match against the destination Salesforce org's User table, and hold any unmatched owners in a reconciliation queue for the customer's admin to provision before record import proceeds. Inactive Sellsation users with historical record assignments are mapped to Salesforce Users with IsActive=false.
Sellsation CRM
Survey Responses
Salesforce Sales Cloud
Task and Custom Fields
1:1Sellsation captures survey responses as activities linked to Contact Persons. We export survey response data as Salesforce Tasks with custom fields capturing response scores and survey identifier, linked via WhatId to the parent Contact. The customer's Salesforce admin can rebuild survey collection using Salesforce Forms or a native Survey tool post-migration.

Migration approach
Export-gap scoping and data audit
We conduct a scoping call to enumerate every Sellsation object (Customers, Contact Persons, Sales Projects, Activities, Campaigns, Tasks, Appointments, custom fields) visible in the UI. We request a full data export from Sellsation support and validate record counts and field coverage against what the UI shows. We identify gaps (missing custom fields, picklist values not in export, orphaned records) and produce a written data audit that defines exactly what migrates and what requires admin-side reconstruction in Salesforce. This step is longer than API-based scoping because there is no programmatic way to enumerate Sellsation's schema.
Salesforce schema design and custom field provisioning
We design the destination schema in Salesforce. This includes creating all custom fields on Account, Contact, Opportunity, Task, Event, and Campaign (with __c API names matched to Sellsation field names where possible), configuring Opportunity Stage values and Sales Processes to match Sellsation pipeline stages, creating any required Record Types for multi-pipeline setups, and provisioning the stagnation_days__c and traffic_light_status__c custom fields that preserve Sellsation's traffic-light logic. Schema deploys into a Salesforce Sandbox via metadata API first for validation.
Sandbox migration and reconciliation
We run a full migration into a Salesforce Sandbox (Full Copy or Partial Copy) with production-like data volume. The customer's admin or RevOps lead reviews record counts per object, spot-checks 25-50 records against Sellsation source data, and validates that Account-Contact-Opportunity relationships resolved correctly. Any field mapping corrections, picklist value mismatches, and OwnerId resolution gaps are fixed in Sandbox before production. This step also validates that Bulk API chunking handles the activity history volume without timeout.
Owner reconciliation and User provisioning
We extract every distinct Sellsation user referenced on Contacts, Accounts, Opportunities, Activities, and Tasks and match by email against the destination Salesforce org's User table. Unmatched owners go to a reconciliation queue. The customer's Salesforce admin provisions any missing Users (active for current employees, inactive for historical assignees). Migration cannot proceed past this step because OwnerId references are required on most standard Salesforce objects and unresolved references cause record rejection.
Production migration in dependency order
We run production migration in record-dependency order: Accounts (from Sellsation Customers), Contacts (with AccountId resolved via Sellsation Customer link), Opportunities (with AccountId, OwnerId, and StageName resolved), Campaigns (with structure and member enrollment), Tasks and Events (via Bulk API 2.0 with time-bounded chunking and WhoId/WhatId resolution), and Appointments as Event records with EventRelation attendees. Each phase emits a row-count reconciliation report before the next begins. Geo map location data loads as custom address and geolocation fields on Opportunity after Opportunity insert.
Cutover, validation, and handoff inventory delivery
We freeze Sellsation writes during cutover, run a final delta migration of any records modified during the migration window, then enable Salesforce as the system of record. We deliver the handoff inventory: a written map of every Sellsation automation and campaign logic requiring rebuild in Salesforce Flow, a territory map rebuild recommendation using AppExchange tools, and a custom report rebuild guide with recommended Salesforce Report Types and Dashboard components. We support a one-week hypercare window for reconciliation issues. Workflow, automation, and dashboard rebuild are outside standard migration scope.
