Overview
Moving from Sellsation CRM to Zoho CRM is a migration from a single-market European platform to one of the world's most widely deployed CRM ecosystems, with 45+ integrated Zoho applications and over 556 verified reviews on Gartner Peer Insights. Sellsation has no documented public API, so we extract via CSV exports enumerated during a full scoping call and validated against UI-exportable record counts. We map Customers to Accounts, Contact Persons to Contacts, and Sales Projects to Deals, preserving pipeline stage names and deal values as Zoho picklists and currency fields. Activity history—calls, appointments, notes, and tasks—migrates in time-bounded batches to avoid the bloat that occurs when years of engagement records outnumber contacts 10-20x. We flag Zoho's 300-field-per-module limit during scoping and collapse or re-home any overflow fields before migration day. Workflows, multi-level campaigns, and custom reports do not migrate; we deliver the underlying data so your Zoho admin rebuilds reports from complete source records rather than starting from scratch.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.

Object mapping
Each row shows how a Sellsation CRM object lands in Zoho CRM, 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
Zoho CRM
Account
1:1Sellsation Customers are the primary account-level records storing company information, linked to Contact Persons and Sales Projects. We map them 1:1 to Zoho CRM Accounts, preserving company name, address, industry classification, and any custom fields. The Account is the first object migrated because every Contact Person has a required or optional link to a Customer; the Account record must exist before Contact import to satisfy lookup resolution. We extract the Customer-to-Contact link during scoping and resolve the Zoho Account record ID before inserting each Contact.
Sellsation CRM
Contact Person
Zoho CRM
Contact
1:1Sellsation Contact Persons map directly to Zoho CRM Contacts. We preserve full name, email, phone, job title, and the Customer link as a ParentId reference to the migrated Account. Activity history attached to the Contact Person (calls, appointments, notes) migrates separately in the Activities phase with Contact lookup resolved via email or name dedupe. Custom fields on Contact Persons are enumerated during scoping and mapped to Zoho CRM custom fields on the Contact module, with field type validation to ensure picklists and date formats are correctly set.
Sellsation CRM
Sales Project
Zoho CRM
Deal
1:1Sellsation Sales Projects are the deal/opportunity records tracked through pipeline stages with automated potential analysis. We map them 1:1 to Zoho CRM Deals, preserving the deal name, value (Amount field), pipeline stage as a Zoho Stage picklist value, and phase change history as a Note attached to the Deal. The Sellsation traffic-light status (red/amber/green flag for stagnating deals) migrates as a custom picklist field on the Deal so the sales manager retains visibility into neglected deals without rebuilding the alert logic from scratch.
Sellsation CRM
Pipeline Stage
Zoho CRM
Stage (on Deal)
lossySellsation pipeline stage names migrate as Zoho CRM Stage values on the Deal module. We create Stage entries in Zoho's pipeline configuration to match the source stage names exactly so that historical deal status is preserved without renaming. If the customer uses multiple Sellsation pipelines, we configure multiple Zoho CRM Deal pipelines (or use Zoho's Stage field with custom picklist groups) to maintain separation. Stage probability percentages from Sellsation are not natively stored but can be documented as a configuration note for the customer's admin to set in Zoho.
Sellsation CRM
Activity (Call, Appointment, Note, Task)
Zoho CRM
Task, Event, Note
1:manySellsation logs every call, appointment, note, and task as a separate Activity record attached to a Contact Person or Sales Project. We split these by type during transformation: call activities map to Zoho Task with Subform or Call fields for duration and disposition; appointments map to Zoho Event with start/end time, duration, and attendee list; notes map to Zoho Notes; tasks map to Zoho Tasks with due date and assignee. Sellsation activity counts frequently exceed contact counts by 10-20x, so we batch activity exports into time-bounded chunks (e.g., quarterly) and resolve the Contact lookup by email match before inserting into Zoho. Activity timestamps are preserved for chronological ordering in the Zoho timeline view.
Sellsation CRM
Campaign
Zoho CRM
Campaign
1:1Sellsation multi-level campaigns combine emails, letters, conditional stage movements, and automated task creation. Zoho CRM Campaign records store campaign metadata (name, type, status, start/end date) and enrollment lists. The conditional stage-movement logic and automated task creation are automation configurations that do not migrate as code. We export campaign enrollment data (which Contact Persons were enrolled in which campaigns) as Campaign Member records in Zoho, and deliver a written inventory of the campaign logic describing triggers, conditions, and actions for the customer's Zoho admin to rebuild using Zoho Workflow Rules and Blueprints.
Sellsation CRM
Task
Zoho CRM
Task
1:1Standalone Tasks in Sellsation (assigned to users with due dates, linked to Contact Persons or Sales Projects) map directly to Zoho CRM Tasks. We preserve Status, Priority, Due Date, Assigned To, and the link to the parent Contact or Deal by resolving the Contact lookup via email dedupe and the Deal lookup via Deal name match. Task descriptions and any attached notes migrate as Task descriptions.
Sellsation CRM
Appointment
Zoho CRM
Event
1:1Calendar appointments in Sellsation with date, time, duration, location, and attendees linked to Contact Persons map to Zoho CRM Events. We preserve Start DateTime, End DateTime, Event Title, Location, and the attendee list as Event Relations pointing to the migrated Contact records. If Sellsation stores recurring appointment patterns, we document the recurrence rule as a configuration note for the customer's Zoho admin to implement via Zoho's recurring event feature.
Sellsation CRM
Custom Fields
Zoho CRM
Custom Fields
lossySellsation custom fields on Customers, Contact Persons, and Sales Projects are enumerated during scoping and mapped to Zoho CRM custom fields on the corresponding modules. Zoho CRM limits each module to 300 fields with only 5 lookup fields per module. During scoping we count all standard and custom fields per module and flag any module that approaches or exceeds this limit. Overflow fields are re-homed to related modules as additional properties, converted to multi-select picklists to consolidate related flags, or documented for removal with the customer's approval before migration day.
Sellsation CRM
Geo Map Data
Zoho CRM
Address and Location Fields on Account/Deal
lossySellsation's geo map feature stores territory heatmap and candidate location data as internal map state rather than standard geographic coordinates. We export the linked Sales Project location data as standard address fields (Street, City, State, Postal Code, Country) on the Account or Deal record in Zoho. The heatmap visualization itself cannot be replicated since Zoho CRM does not have a native territory heatmap module; we document the geographic fields available for reporting in Zoho Analytics or third-party mapping tools. The customer's admin can build territory reports using Zoho Analytics' geographic visualization features from the migrated address data.

KPIs and Reports
Zoho CRM
Data Export for Rebuild
1:1Sellsation standard and custom reports store report definitions that do not have a direct export mechanism. We export the underlying data—Sales Projects with values and stages, Contact Persons with activity counts, and campaign performance metrics—so the customer's Zoho admin rebuilds reports from complete source records rather than starting from scratch. We deliver a written report inventory listing each Sellsation report by name, its underlying data sources, its filters, and the recommended Zoho CRM or Zoho Analytics equivalent. This gives the admin a rebuild specification rather than a blank canvas.

Pair-specific challenges
Migration approach
Scoping call and field inventory
We conduct a structured discovery call to enumerate all Sellsation objects in use: Customers, Contact Persons, Sales Projects, Activities, Campaigns, Tasks, Appointments, and any custom fields. We request CSV export samples from each object to verify field coverage and identify any fields that are not exportable via the UI. We count total records per object, total activities, and estimate activity-to-contact ratio to size the migration batch plan. We also audit Zoho CRM's destination environment for existing modules, custom fields, and lookup relationships to identify namespace conflicts before design begins.
Schema design and field-limit audit
We design the destination Zoho CRM schema: provisioning custom fields on Account, Contact, Deal, Task, Event, Note, and Campaign modules; configuring Deal stages to match Sellsation pipeline stage names; and creating any required Zoho CRM custom modules for Sellsation objects without a standard equivalent. The Zoho field-limit audit (300 fields per module, 5 lookups per module) is completed at this stage and any overflow is resolved through re-homing, consolidation, or deprecation with customer sign-off. We produce a written field mapping document that maps every Sellsation field to a typed Zoho field before any data extraction begins.
Data extraction and transformation
We extract data from Sellsation via CSV exports for each object. Activity records are extracted in time-bounded batches to manage volume. During transformation, we resolve Customer-to-Account ID lookups, Contact-to-Account lookups via company name or domain match, Sales Project-to-Contact lookups via Contact email, and Owner-to-User lookups via email address. We apply the traffic-light status as a custom field value, convert Sellsation territory and geo data to standard address fields, and split Sellsation Activities by type into Zoho Task and Event records. Any records with unresolvable lookups (no matching Contact or Account) are placed in a reconciliation queue for the customer's admin to resolve.
Sandbox test migration and validation
We run a full test migration into a Zoho CRM sandbox environment using production-like data volume. The customer's team reconciles record counts against the Sellsation source (Accounts in, Contacts in, Deals in, Activities in), spot-checks 20-30 random records for field-level accuracy, and verifies that deal stage names, contact assignments, and activity timestamps are correct. Any field mapping corrections, lookup resolution failures, or field-limit violations surface here. The customer's admin signs off the sandbox results before production migration is scheduled.
Production migration in dependency order
We run production migration in record-dependency order: Accounts (from Customers) first; Contacts (with AccountId resolved); Deals (with AccountId and ContactId resolved); Campaigns (with enrollment lists); Tasks and Events (with ContactId and DealId resolved via email and name dedupe); Notes. Each phase emits a row-count reconciliation report before the next phase begins. Sellsation writes are frozen during the cutover window and a final delta pass captures any records modified during migration. We use Zoho's API with exponential backoff on rate limit responses and batch chunking for activity records.
Cutover, validation, and rebuild handoff
After final delta migration, we enable Zoho CRM as the system of record and retire Sellsation access for the migration team. We deliver the Report and Dashboard Rebuild Inventory—a written specification for each Sellsation report listing its data sources, filters, and recommended Zoho CRM or Zoho Analytics equivalent. We deliver the Campaign Logic Inventory describing each Sellsation multi-level campaign's triggers and actions for rebuild in Zoho Workflow Rules and Blueprints. We do not rebuild reports, dashboards, or automations as part of the migration scope; that work is handled by the customer's Zoho admin or a Zoho implementation partner.
