Overview

What this migration involves

Moving from Sellsation CRM to Nutshell is a manual-extraction migration because Sellsation publishes no public API, which means CSV exports drive the data extraction phase. We perform a full scoping call to enumerate every object and custom field in the Sellsation instance, export each entity as CSV, validate record counts against the Sellsation UI, then map and import into Nutshell's Companies, People, Deals, Tasks, and Events objects. Sellsation's traffic-light stagnation system maps to a custom Deal status field in Nutshell, and the geo map heatmap data attaches as address metadata to the corresponding Company. Multi-level campaign structures with conditional stage movements do not migrate as automations; we deliver a written campaign inventory for the customer's Nutshell admin to rebuild. The migration typically runs four to eight weeks from scoping to cutover, depending on activity history volume and data cleanliness.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Why teams make this switch

Two sides of the same decision

Leaving

Sellsation CRM logo

Sellsation CRM

What's pushing teams away

  • Very limited third-party review presence—only one verified G2 review exists for Sellsation CRM, making it difficult for migration teams to find independent validation of feature claims before committing.
  • Small market footprint outside German-speaking regions—the company is headquartered in Linz and Vienna, Austria, and most customer-facing content is German-language, limiting appeal and support depth for English-speaking teams.
  • Unclear API availability and export capabilities—no public API documentation was found in research, creating risk for teams needing programmatic data extraction or automation-driven migrations.
  • Competitors offer broader ecosystem integrations—G2 lists Salesforce Sales Cloud, ActiveCampaign, and HubSpot as the top Sellsation alternatives, all of which have richer app marketplace ecosystems and integration libraries.

Choosing

Nutshell logo

Nutshell

What's pulling them in

  • Lowest cost entry point among mid-market CRMs—Foundation plan starts at $13/user/month, making it accessible for teams validating CRM fit before committing.
  • Integrated sales automation and email sequencing on Pro plans without requiring a separate email marketing platform, per verified Capterra reviews.
  • Consistently praised for intuitive interface and fast onboarding, with case studies reporting 100% team adoption rates within initial deployment periods.
  • Strong customer support responsiveness cited across G2 reviews, with dedicated support tiers available on Enterprise plans.
  • Native integrations with WhatsApp, Facebook Messenger, Instagram, and Slack reduce reliance on third-party middleware for common communication channels.

Object mapping

How Sellsation CRM objects map to Nutshell

Each row shows how a Sellsation CRM object lands in Nutshell, 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

maps to

Nutshell

Company

1:1
Fully supported

Sellsation Customers are the primary account-level records and map directly to Nutshell Company records. The Customer name, address, phone, website, and industry fields map to the corresponding Nutshell Company fields. We use the Customer's primary address as the Company address and preserve any geo map location metadata as a custom address field or note attachment. Company is the first object imported because all Contact Persons and Sales Projects reference their parent Customer.

Sellsation CRM

Contact Person

maps to

Nutshell

Person

1:1
Fully supported

Sellsation Contact Persons map 1:1 to Nutshell People records. Each Contact Person's name, email, phone, role, and linked Customer reference migrates to the Person record with the Customer-to-Company lookup resolved at import time. Full activity history including calls, meetings, and notes attaches to the Person record in Nutshell. Duplicate detection in Nutshell uses email as the dedupe key during import.

Sellsation CRM

Sales Project

maps to

Nutshell

Deal

1:1
Fully supported

Sellsation Sales Projects map to Nutshell Deals. The pipeline stage name migrates as the Deal's pipeline stage, and Sellsation's automated potential analysis value maps to a custom field on the Deal. Sellsation's traffic-light stagnation flag (red/yellow/green deal status) maps to a custom Deal status field since Nutshell does not have a native traffic-light system. Closed-Lost and Closed-Won dates migrate as custom fields if the Nutshell account uses a Deal edition that supports them.

Sellsation CRM

Activity (calls, appointments, notes)

maps to

Nutshell

Task and Event

1:1
Fully supported

Sellsation Activities are individual records attached to Contact Persons or Sales Projects. Calls map to Nutshell Tasks with type set to Call and duration stored in a custom field. Appointments with date, time, and attendees map to Nutshell Events with attendee lists preserved as notes or custom fields. Notes map to Nutshell Task records with type set to Note. All activity timestamps migrate as ActivityDate to preserve the chronological timeline in Nutshell's People record.

Sellsation CRM

Task

maps to

Nutshell

Task

1:1
Fully supported

Sellsation Tasks assigned to users with due dates map directly to Nutshell Tasks. Task status, priority, and the linked Contact Person or Sales Project reference migrate with the parent lookup resolved at import time. Completed tasks preserve their completion date; open tasks preserve the due date and assignment. Tasks without a resolved parent record are held in a reconciliation queue for the customer to clarify before import.

Sellsation CRM

Campaign

maps to

Nutshell

Campaign (mapping)

1:1
Fully supported

Sellsation's multi-level campaigns with conditional stage movements and automated task creation do not have a direct Nutshell equivalent. Nutshell supports basic campaign tracking for list-based email sends but does not support conditional stage movement automation or multi-level campaign structures natively. We export the campaign enrollment data and campaign structure as a CSV mapping document that the customer's Nutshell admin uses to rebuild campaigns using Nutshell's basic campaign lists or an external automation tool like Zapier.

Sellsation CRM

Custom Fields

maps to

Nutshell

Custom Fields

lossy
Mapping required

Sellsation custom fields on Customers, Contact Persons, and Sales Projects map to Nutshell custom properties. We enumerate all custom fields during scoping, verify field types (text, number, date, picklist) during export, and create matching custom properties in Nutshell before import. Picklist-based custom fields from Sellsation require manual value mapping in Nutshell if the picklist values differ between systems.

Sellsation CRM

Geo Map Data

maps to

Nutshell

Company Address Fields

1:1
Mapping required

Sellsation's geo map and heatmap data is stored as internal map state rather than standard geographic coordinates. We extract the linked Sales Project location data as standard address fields (street, city, region, postal code, country) and attach the original Sellsation location reference as a custom note on the Company record. The native heatmap visualization does not migrate since Nutshell does not support that visualization type.

Pair-specific challenges

  • No public API means CSV export with unknown field coverage

    Sellsation CRM publishes no documented API, so all data extraction relies on CSV exports from the Sellsation UI or manual data pulls. This means we cannot programmatically enumerate the Sellsation schema before export. We address this with a full scoping call to enumerate every object and custom field directly with the customer's Sellsation admin, then cross-validate exported CSV field headers against the enumerated list to identify any fields that are visible in the UI but not in the export. Gaps are resolved by requesting additional exports or accepting that certain fields require manual re-entry in Nutshell.

  • Multi-level campaign automation does not migrate

    Sellsation's multi-level campaigns combine emails, letters, conditional stage movements, and automated task creation into a single structured workflow. Nutshell supports basic campaign tracking for list-based sends but does not replicate conditional branching, stage-movement triggers, or automated task generation. We export campaign enrollment data and campaign structure as a written mapping document for the customer's Nutshell admin to rebuild using Nutshell Sequences (on Pro+ plans) or an external automation platform. The original campaign automation logic cannot be imported.

  • Traffic-light stagnation data requires custom field reconstruction

    Sellsation's traffic-light system automatically assigns red, yellow, or green flags to deals based on stagnation and activity metrics. Nutshell has no native traffic-light equivalent. We map the traffic-light status to a custom Deal field (e.g., deal_health__c) using the last known flag value from Sellsation. The dynamic re-evaluation of deal health does not continue in Nutshell unless the customer implements a Nutshell Workflow or external automation to replicate the logic.

  • Activity history volume can cause CSV bloat and import timeout

    Sellsation logs every call, appointment, note, and task as a separate activity record, and teams with multiple years of engagement history can accumulate activity counts 10-20x their contact count. We chunk activity exports into time-bounded batches (e.g., six-month windows) and map them to Nutshell's Task and Event schema in sequence. Nutshell's in-app CSV import supports bulk loading but we validate batch sizes against Nutshell's documented import limits and use API-based insertion for accounts exceeding the spreadsheet import threshold.

  • Custom reports and dashboards do not migrate

    Sellsation allows custom report and dashboard development, particularly on the Salesleader tier. These are platform-native configurations with no export mechanism. We export all underlying data—Sales Projects, activity history, KPIs, and custom field values—so the customer's Nutshell team can rebuild reports from complete source data. We deliver a written inventory of the original Sellsation report structure for reference during rebuild.

Migration approach

Six steps for a successful Sellsation CRM to Nutshell data migration

  1. Discovery and CSV export enumeration

    We schedule a scoping call with the customer's Sellsation admin to enumerate every object, custom field, pipeline stage name, and activity type in the Sellsation instance. We identify which objects and fields are visible in the Sellsation UI versus what is exportable via CSV. We extract record counts for each object and flag any objects that appear to lack export capability, which may require manual re-entry in Nutshell. The discovery output is a written migration scope with a CSV export checklist for the customer's Sellsation admin to execute.

  2. CSV validation and data quality assessment

    We receive the exported CSV files and validate them against the scoping checklist: all enumerated fields are present, record counts in CSV match the counts reported in Sellsation, date formats are consistent, and email addresses are structurally valid. We identify duplicates, missing required fields, and orphaned records (Contact Persons with no Customer link, Sales Projects with no Contact Person link). We deliver a data quality report to the customer and agree on a data-cleansing approach before import begins.

  3. Nutshell schema setup and custom field provisioning

    We create the custom fields in Nutshell to host Sellsation-specific data that has no native Nutshell equivalent, including the traffic-light deal health field, any Sellsation custom properties, and the original Sellsation record ID for audit purposes. We configure the Deal pipeline stages to match the Sellsation pipeline stage names as closely as possible and set stage probabilities. Nutshell's custom fields are created before any data import so that the import mapping can reference them directly.

  4. Import in dependency order: Companies, People, Deals, Activities

    We import in record-dependency order: Companies first (from Sellsation Customers), then People (from Contact Persons) with the Customer-Company lookup resolved at import time, then Deals (from Sales Projects) with the Contact Person-User assignment and pipeline stage resolved, then Activities (Tasks, Events, Notes) in time-bounded batches with parent-record lookups validated before each batch. Each phase emits a row-count reconciliation report before the next phase begins.

  5. Campaign inventory and automation handoff

    We export the Sellsation campaign structure and enrollment data as a CSV mapping document. This includes campaign names, enrolled Contact Persons, campaign stage, conditional rules, and associated automated tasks. We do not rebuild campaigns in Nutshell because Nutshell's campaign model and Sellsation's multi-level campaign model are structurally different. The handoff document provides the customer's Nutshell admin with enough context to rebuild campaigns using Nutshell Sequences or an external automation platform.

  6. Cutover, validation, and data reconciliation

    We freeze Sellsation writes during cutover, run a final delta migration of any records modified during the migration window, then mark Nutshell as the system of record. We deliver a reconciliation report comparing record counts between the Sellsation export and the Nutshell import, flagging any gaps. We support a one-week hypercare window for the customer's team to report missing or incorrectly mapped records. Custom reports, dashboards, and automations are outside migration scope; we provide the underlying data for the customer's Nutshell admin to rebuild.

Most migrations land between four and six weeks for accounts with under 10,000 Customers, 2,000 Sales Projects, and manageable activity history volumes. Migrations with large engagement histories exceeding 100,000 activity records, multiple custom field objects, or accounts showing significant data quality issues requiring cleansing move to six to ten weeks. The CSV export phase adds one to two weeks to the timeline compared to API-based migrations because each export must be manually requested from Sellsation and validated before import begins.
