Overview

What this migration involves

Sellsation CRM stores contacts, companies, sales projects (deals), multi-level campaigns, and activity records (calls, tasks, meetings, notes) in a flat, stage-driven object model. Sellsation pipelines operate as a sequence of stages with automated conditional triggers per stage — a model that has no direct equivalent in HubSpot. HubSpot uses its own deal pipeline architecture with stages, probability weights, and a separate association system for contact-deal relationships. We extract Sellsation records via the platform's export API, map every standard field by name, create HubSpot custom properties for Sellsation custom fields, and resolve Sellsation owner assignments by matching against HubSpot user email addresses. Sellsation's multi-level campaign structures, automated follow-up sequences, and stage-movement rules are exposed as plain-data exports and rebuilt manually in HubSpot workflows. A 24–48 hour delta window captures any Sellsation changes made during the cutover. We run a sample migration of 100–500 records first with field-level validation, then commit the full dataset once you sign off on the diff.

Why teams make this switch

Two sides of the same decision

Leaving

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

HubSpot

What's pulling them in

  • Lowest barrier to entry of any major CRM — the free tier with unlimited contacts lets teams validate fit before committing to a paid plan, according to G2 and Capterra reviewers.
  • Native integration between the CRM and sales engagement tools (sequences, email tracking, dialer) means no separate sync configuration, a theme across G2 Sales Hub reviews.
  • Pipeline visualization, deal tracking, and automated workflows are consistently praised as intuitive and easy to set up without developer involvement.
  • Strong onboarding for new team members — reviewers on Capterra and G2 highlight how quickly new reps become productive without formal training.
  • The HubSpot platform ecosystem (Marketing, Sales, Service, CMS hubs) allows growing companies to consolidate tools without building new integrations.

Object mapping

How Sellsation CRM objects map to HubSpot

Each row shows how a Sellsation CRM object lands in HubSpot, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

Sellsation CRM

Contact

maps to

HubSpot

Contact

1:1
Fully supported

Sellsation contacts migrate as HubSpot contacts. The primary company link (if set) maps to the HubSpot contact's associated company. Sellsation contacts without a company association land in HubSpot without a company link — flagged for manual review if you need company association.

Sellsation CRM

Company

maps to

HubSpot

Company

1:1
Fully supported

Sellsation company records map to HubSpot company records 1:1 by name. Domain, industry, employee count, and annual revenue map to HubSpot standard company properties. Sellsation's corporate structures and multiple locations are preserved as a custom text property since HubSpot companies are flat.

Sellsation CRM

Sales Project (Deal)

maps to

HubSpot

Deal

1:1
Fully supported

Sellsation sales projects map to HubSpot deals. The deal name, amount, and close date migrate directly. The Sellsation stage name maps to a HubSpot deal pipeline stage — if you have custom stage names, we create matching HubSpot stages before import.

Sellsation CRM

Stage / Pipeline

maps to

HubSpot

Deal Pipeline + Stage

1:1
Fully supported

Sellsation stage names are mapped to HubSpot deal pipeline stage names value-by-value. If Sellsation uses custom stage labels (e.g., 'Negotiation', 'Offer Sent'), those get created as HubSpot stage names in your deal pipeline before the migration runs. Stage-entry timestamps are preserved as HubSpot custom date properties.

Sellsation CRM

Activity: Call / Task

maps to

HubSpot

Engagement (Call)

1:1
Fully supported

Sellsation logged calls and tasks migrate as HubSpot engagement calls. The original timestamp, duration, outcome, and owner are preserved. The engagement links back to the HubSpot contact or company record that was the subject of the call and provides a full call history for each contact.

Sellsation CRM

Activity: Meeting

maps to

HubSpot

Engagement (Meeting)

1:1
Fully supported

Sellsation meetings migrate as HubSpot meeting engagements with original start/end times, location, title, and owner preserved. Meeting notes from Sellsation attach as a note on the HubSpot engagement record. This preserves the complete meeting history and allows your team to review details directly within HubSpot's timeline.

Sellsation CRM

Activity: Email

maps to

HubSpot

Engagement (Email)

1:1
Fully supported

Sellsation logged emails migrate as HubSpot email engagements on the contact or company record. Subject line, body text, and timestamp are preserved. Sellsation email sequences sent from within the CRM map to HubSpot workflow enrollments that must be rebuilt. This ensures email history is available for reference in HubSpot.

Sellsation CRM

Activity: Note

maps to

HubSpot

Note

1:1
Fully supported

Sellsation notes migrate as HubSpot notes on the associated contact or company. Rich-text formatting from Sellsation is preserved where possible. Notes attached to a specific sales project link to the corresponding HubSpot deal record. This maintains context and supports detailed activity tracking.

Sellsation CRM

Multi-level Campaign

maps to

HubSpot

HubSpot Workflow

1:1
Fully supported

Sellsation multi-level campaigns — combining automated emails, stage shifts, task triggers, and conditional branches — have no HubSpot equivalent at the data level. We export the campaign definition as a structured document that your HubSpot admin uses to rebuild the logic in HubSpot workflows after migration.

Sellsation CRM

Survey Response

maps to

HubSpot

Custom Object or Note

1:1
Fully supported

Sellsation customer satisfaction survey responses are preserved as HubSpot notes or a custom object, linked to the original contact. The survey questions and answer values are stored as a text blob — they do not become native HubSpot survey responses.

Sellsation CRM

Product / Offering

maps to

HubSpot

Product

1:1
Fully supported

Sellsation products linked to sales projects migrate to HubSpot products. Name, SKU, price, and description map to HubSpot product fields. Products are migrated before deals so line-item associations resolve correctly at import time. This ordering ensures product data is ready for deal linking and reporting.

Sellsation CRM

Custom Field (any object)

maps to

HubSpot

Custom Property

1:1
Fully supported

Sellsation custom fields on contacts, companies, or deals become HubSpot custom properties. Each custom property is created in HubSpot before the migration run, typed to match the source (text, number, date, checkbox, or picklist). Picklist values are mapped value-by-value to HubSpot picklist options.

Pair-specific challenges

  • Sellsation multi-level campaign logic has no HubSpot equivalent

    Sellsation's multi-level campaigns combine automated emails, conditional stage movements, task triggers, and follow-up survey logic in a single campaign object. HubSpot separates these concepts: email sequences live in HubSpot's workflow engine, task triggers are separate workflow actions, and survey logic is its own module. There is no single object that captures a Sellsation campaign as a whole. We export the campaign definition as a structured document — your HubSpot admin rebuilds the logic manually in HubSpot workflows after the data migration completes. Plan 2–4 hours per complex Sellsation campaign for the rebuild.

  • Sellsation stage-entry timestamps require custom HubSpot date properties

    HubSpot deals natively track only the current stage name and probability — not when a deal entered each stage historically. Sellsation records stage-entry timestamps as part of its sales project history. When migrating deals, we create HubSpot custom date properties (e.g., Stage_Entered_Date__c) for each Sellsation stage that carries a timestamp. Your reporting team references these custom fields in HubSpot reports rather than relying on the native deal stage timestamp. This ensures your team can track deal progression over time and generate historical trend reports.

  • Sellsation corporate structures and multi-location data must be flattened

    Sellsation supports corporate hierarchies and multiple office locations per company record. HubSpot companies are flat records with no native parent-company or multi-location fields. We preserve the full Sellsation corporate structure as a custom text property (Corporate_Structure__c) on the HubSpot company record. If you need parent-child reporting in HubSpot, your admin must decide whether to use HubSpot's account hierarchies (available in Enterprise tiers) or maintain the structure as a custom property.

  • HubSpot contact lifecycle stage is empty for all migrated contacts

    Sellsation does not have a native contact lifecycle stage property equivalent to HubSpot's lifecycle_stage field. After migration, every contact's lifecycle_stage is unset. Your team sets lifecycle stages manually post-migration or runs a HubSpot workflow to assign them based on deal history (e.g., a contact associated with a closed-won deal becomes 'Customer'). This is not data loss — it is a property that did not exist in Sellsation. Consider assigning lifecycle stages early to keep your marketing and sales alignment intact.

  • Sellsation survey responses migrate as notes, not native HubSpot survey responses

    Sellsation's automated customer satisfaction measurement records responses linked to a contact or sales project. HubSpot has a separate survey product (HubSpot Surveys) that collects responses natively. Migrated survey responses land as HubSpot notes on the contact record with the response text stored as plain text. They do not appear in HubSpot's native survey analytics dashboard — that is a rebuilt use case, not a migration one. You can export them for external reporting if needed.

Migration approach

Six steps for a successful Sellsation CRM to HubSpot data migration

  1. Extract and audit Sellsation data

    FlitStack AI pulls all contacts, companies, sales projects, activities, products, and custom field definitions from Sellsation via the platform's export API. We produce a data audit report showing record counts per object, custom field list with types, pipeline and stage definitions, and owner assignments. This report is your baseline for the migration scope and identifies any data quality issues (duplicate contacts, missing company associations, stale deals) before mapping begins.

  2. Plan field mapping and create HubSpot custom properties

    We map every Sellsation field to its HubSpot equivalent. Standard fields map by name. Sellsation custom fields require HubSpot custom properties to be created first — we create these in your HubSpot portal with the correct type (text, number, date, checkbox, picklist) before the migration run. For Sellsation stage names, we map each to a HubSpot deal stage and create any missing stages in your HubSpot pipeline before import.

  3. Run a sample migration with field-level diff

    A representative slice of 100–500 records migrates first — spanning contacts, companies, deals, and activities. We generate a field-level diff between the Sellsation source values and the HubSpot destination values so you can verify that custom property creation, stage mapping, owner resolution, and company association are working as expected. No record is permanently committed until you approve the diff. This validation step ensures data integrity before the full load.

  4. Execute full migration with delta-pickup window

    Once the sample migration is approved, the full dataset migrates to HubSpot. A 24–48 hour delta-pickup window runs after the initial load to capture any Sellsation records created or modified during the cutover. FlitStack AI logs every operation to an audit trail. If reconciliation reveals record-count gaps or field-level discrepancies, one-click rollback reverts the migration so the issue can be resolved before re-running.

  5. Validate, reconcile, and hand off rebuild documentation

    After the migration and delta window close, we validate record counts across all objects, spot-check field-level accuracy on a random sample, and confirm that contact-company and contact-deal associations resolved correctly. We deliver the Sellsation multi-level campaign export document to your HubSpot admin for workflow rebuild. Post-migration, your team receives a validation report and a 14-day support window for any reconciliation questions.

Platform deep dives

Context on both ends of the pair

Sellsation CRM logo

Sellsation CRM

Source

Strengths

  • Annual billing at 90–100 € per user with no long-term contract commitment
  • Traffic-light system automatically flags stagnating deals and neglected contacts
  • Automated potential and strengths/weaknesses analysis per Sales Project
  • Multi-level campaign and workflow automation combining emails, tasks, and stage movements
  • Geo map feature with heatmaps for territory analysis and regional pursuit tracking

Weaknesses

  • No publicly documented API—migration requires CSV/manual export with unknown field coverage
  • Only one verified third-party review exists on G2, limiting independent validation
  • German-language primary market presence with limited English documentation
  • Small company footprint raises long-term viability and support continuity questions
  • Custom reports and dashboards are platform-native and must be rebuilt after migration

HubSpot

Destination

Strengths

  • Genuinely useful free CRM tier with no seat limit on contact records.
  • All-in-one sales engagement layer (sequences, email tracking, calling, dialer) embedded natively in the CRM, eliminating a separate integration.
  • Intuitive interface and fast onboarding for individual reps, per G2 and Capterra reviews.
  • Workflow automation triggers across contacts, deals, and tickets with a visual builder.
  • API coverage for all standard objects including custom objects at Enterprise tier.

Weaknesses

  • Pricing model is contact-based at the marketing layer — importing all records as marketing contacts can multiply the monthly bill by 4×.
  • Feature tier cliffs are frequent surprises: sequences, calling, advanced reporting, and quoting are all gated, often requiring plan upgrades mid-implementation.
  • Mandatory onboarding fees at Professional ($1,500) and Enterprise ($3,500) are not prominently disclosed on the pricing page.
  • API rate limits are restrictive for bulk migration — burst limits of 100-200 req/10sec and search endpoint limits of 4 req/sec require careful job queuing.
  • Custom objects, additional pipelines, and advanced forecasting are Enterprise-only, making cost projections difficult for growing teams.

Most Sellsation CRM to HubSpot migrations complete in 48–72 hours of clock time for under 30,000 total records. Larger datasets with 200,000+ records or setups with more than 20 Sellsation custom fields per object extend to 7–10 days. The longest step is creating and validating HubSpot custom properties and pipeline stages before data lands — that planning phase typically takes 2–3 business days before the first record moves.
