How long does a TeamSystem CRM to Nutshell migration take?

Standard migrations with clean CRM data (under 15,000 contacts, 3,000 companies, 2,000 deals, and no more than 50,000 activity records) complete in two to four weeks. Migrations with large custom field sets, extensive engagement histories, or organizations that have multiple TeamSystem modules active simultaneously take six to ten weeks. The data separation phase (identifying CRM-layer tables within the unified schema) adds one to two weeks to the timeline compared to migrations from standalone CRMs.

Do TeamSystem workflow automation rules migrate to Nutshell?

No. TeamSystem workflow configurations are stored in the ERP-CRM integration layer and are not accessible as exportable data records. We do not migrate them as code. We deliver a written inventory of every active TeamSystem workflow with its trigger, conditions, and actions, plus a recommended Nutshell Rules equivalent. The customer's admin rebuilds these post-migration using Nutshell's built-in Rules feature or the Engagement suite. Any automations that depend on TeamSystem's ERP layer (e.g., invoice-triggered follow-ups) do not have a direct Nutshell equivalent and are flagged for the customer's IT team to address.

What does a TeamSystem CRM to Nutshell migration typically cost?

Migrations land between $4,500 and $7,500 for standard scope (under 15,000 contacts, 3,000 companies, 2,000 deals) with a clean CRM layer extraction. Migrations with extensive custom fields, large activity histories, or complex ownership structures requiring extensive user reconciliation move to $8,000-$12,000. Nutshell subscription (Foundation at $16/user/month through Enterprise at $67/user/month on annual billing) is separate from the migration fee and becomes the customer's ongoing cost after go-live.

Can we keep TeamSystem ERP while moving only the CRM layer to Nutshell?

Yes. This is one of the most common migration patterns from TeamSystem. The customer continues using TeamSystem for accounting, payroll, and back-office operations while Nutshell handles all sales CRM activity. We extract only the CRM-layer records from TeamSystem during migration and exclude financial records. The customer should coordinate with TeamSystem support to ensure that the CRM module remains accessible after the sales team transitions to Nutshell, or that the accounting layer is accessed independently post-migration.

Do historical activities (calls, emails, meetings) migrate to Nutshell?

Yes. TeamSystem activity logs (calls, emails, meetings, tasks) linked to Contacts or Deals migrate to Nutshell Activity records. We preserve the original activity timestamp, type, and owner assignment. Full email content migrates where the integration configuration supports it; email tracking history (opens, clicks) from TeamSystem does not carry forward because that is a function of TeamSystem's email integration, not the activity record itself. Nutshell's own email tracking activates post-migration and rebuilds engagement data over time.

How do we handle owner assignment during migration?

TeamSystem owner IDs do not map directly to Nutshell usernames. We build a user mapping table during scoping by matching TeamSystem owner email addresses to Nutshell user accounts. The customer creates Nutshell user accounts for each active owner before migration begins. Any TeamSystem owner without a matching Nutshell account is held in a reconciliation queue. Records without a resolved owner are imported as unassigned and the customer assigns them manually after go-live.

What happens to TeamSystem custom fields during migration?

TeamSystem custom fields on Contacts, Companies, Opportunities, and Activities are extracted as part of the CRM-layer export. We map each to a corresponding Nutshell custom field, creating the destination field in Nutshell first if it does not exist. Custom field types (text, numeric, date, picklist) are validated during discovery to prevent import errors. Nutshell's custom field limits vary by plan: Foundation allows fewer custom fields than Pro or Enterprise, so we confirm the target plan during scoping before creating the field schema.

TeamSystem CRM to Nutshell Migration — Field-Level Mapping & Rollback

Overview

What this migration involves

TeamSystem CRM stores CRM objects alongside accounting, payroll, and operational data in a unified schema, making clean CRM extraction a prerequisite before any import begins. We identify which database tables and fields belong to the sales layer versus the ERP layer during discovery, export only CRM data with no financial records included, and map the extracted fields to Nutshell's People (Contacts), Organization (Companies), Deal (Opportunities), and Activity objects. Nutshell's per-user pricing model (starting at $16/user/month on annual billing) contrasts with TeamSystem's custom quotation, and the migration eliminates the IT-dependent overhead that Italian SMBs report as a barrier to adopting lightweight CRMs. Workflow automation rules, custom workflow configurations, and ERP-level integrations do not migrate; we deliver a written inventory of these for your admin to rebuild or retire post-migration.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

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

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

TeamSystem CRM

What's pushing teams away

Some users report that the accounting modules lack the flexibility of dedicated ERP solutions, prompting moves to best-of-breed stacks.
Custom pricing without public tiers makes cost predictability difficult, and organizations on growth trajectories find per-user costs hard to forecast.
The integrated nature of the platform means leaving requires separating years of intermingled CRM and financial data, a barrier that slows adoption of better-fit alternatives.
Smaller teams find the administrative overhead and IT-dependent setup disproportionate to their sales automation needs compared to lighter CRMs.

Choosing

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 TeamSystem CRM objects map to Nutshell

Each row shows how a TeamSystem 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.

TeamSystem CRM

Contact

maps to

Nutshell

Person (People)

1:1

Fully supported

TeamSystem Contact records map to Nutshell Person objects. We extract name fields, email, phone, address, and owner assignment from the CRM layer only. The dedupe key is email address. Owner mapping requires a user lookup table we build during scoping to resolve TeamSystem owner IDs to Nutshell user emails.

TeamSystem CRM

Company

maps to

Nutshell

Organization

1:1

Fully supported

TeamSystem Company records map to Nutshell Organization. The Organization is created before any Person import so that the Person-to-Organization relationship is satisfied at the moment of Person insert. We preserve the domain and address fields as Organization properties.

TeamSystem CRM

Lead

maps to

Nutshell

Lead

1:1

Fully supported

TeamSystem Lead records with status, source, and scoring fields migrate directly to Nutshell Lead. Lead status values are mapped to Nutshell's Lead status picklist. Any scoring fields stored as numeric custom properties migrate as Nutshell custom fields if the target plan supports them.

TeamSystem CRM

Opportunity

maps to

Nutshell

Deal

1:1

Fully supported

TeamSystem Opportunity records map to Nutshell Deal. Deal value, expected close date, and stage name migrate directly. The TeamSystem pipeline stage ordering and probability percentages are preserved as Nutshell custom stage configuration options. We configure loss reason and win reason fields in Nutshell before migration to match TeamSystem's deal outcome tracking.

TeamSystem CRM

Pipeline

maps to

Nutshell

Deal Stages

lossy

Fully supported

TeamSystem pipeline definitions (stage names, sequence, and probabilities) map to Nutshell's Deal stage configuration. Custom stage counts and stage names vary per TeamSystem organization, so we extract the actual pipeline configuration from the CRM layer during discovery and build the corresponding Nutshell stage list before any Deal import runs.

TeamSystem CRM

Activity (calls, emails, meetings, tasks)

maps to

Nutshell

Activity

1:1

Fully supported

TeamSystem activity logs linked to Contacts or Deals migrate to Nutshell Activity records. Activity types are mapped to Nutshell's activity taxonomy (Call, Email, Meeting, Task). We preserve the original activity timestamp and owner assignment by resolving the owner ID through the user mapping table built during scoping.

TeamSystem CRM

Custom Fields

maps to

Nutshell

Custom Fields

1:1

Mapping required

TeamSystem organization-specific fields on any standard object require a field registry query before export to ensure all non-standard columns are included in the migration package. We map each extracted custom field to a corresponding Nutshell custom field, creating the destination field in Nutshell first if it does not exist. Custom field type mapping (text, number, date, picklist) is validated during the discovery phase to prevent type mismatch errors on import.

TeamSystem CRM

Email Integration Data

maps to

Nutshell

Activity (Email)

1:1

Mapping required

Email history linked to Contacts migrates as Nutshell Activity records with type Email. Full email content may require a separate export step depending on the integration configuration in TeamSystem. We extract email body, subject, timestamp, and linked contact reference. Nutshell's email features (email open tracking, link click tracking) activate post-migration and do not carry forward from TeamSystem's integration.

Pair-specific challenges

ERP-CRM data separation must precede any export

TeamSystem stores CRM records (Contacts, Deals, Activities) in the same database as financial records (invoices, payroll, chart-of-accounts entries). Extracting only the CRM layer requires identifying which tables and fields belong to the sales module before export begins. We build a data separation map during discovery and export only CRM-layer records. Failing to perform this separation risks including sensitive financial data in the migration package or omitting CRM records that live in shared tables.
TeamSystem API is not publicly documented

TeamSystem does not publish comprehensive API documentation in English. The public GitHub organization (CRM-in-Cloud) shows code samples for basic integrations (lead generation, WordPress forms) but the full API surface for exporting Opportunities, Custom Fields, and Activities is not publicly accessible. We engage the customer's IT team or TeamSystem support directly to obtain API credentials and endpoint details. In cases where API access is restricted or rate-limited below what the migration requires, we fall back to a coordinated database-level export with vendor involvement.
Custom fields require pre-migration registry extraction

TeamSystem organizations commonly add custom fields to Contacts, Companies, and Opportunities for industry-specific tracking. These custom fields are not included in a standard export unless the field registry is queried explicitly before extraction. We query the field registry during the discovery call, create the corresponding Nutshell custom fields before migration begins, and validate field types (text, numeric, picklist) to prevent import rejection. Nutshell's custom field limits vary by plan (Foundation, Pro, Power AI, Enterprise), so plan selection is confirmed before custom field creation begins.
Workflow automation rules do not export from TeamSystem

TeamSystem workflow configurations live in the ERP-CRM integration layer and are not accessible as discrete data records for export. We do not migrate workflow rules as code. We deliver a written inventory of every active TeamSystem workflow with its trigger, conditions, actions, and a recommended Nutshell automation equivalent (Nutshell's Rules feature or the Engagement suite's sequencing tools). The customer's admin rebuilds these post-migration. Additionally, any integrations built on TeamSystem's ERP layer (e.g., accounting sync, payroll triggers) do not migrate and are flagged separately for the customer's IT team to evaluate against Nutshell's available integrations.

Migration approach

Six steps for a successful TeamSystem CRM to Nutshell data migration

Discovery and data separation mapping

We audit the TeamSystem CRM environment through the customer's IT team or direct database access. This includes identifying CRM-layer tables (Contacts, Companies, Opportunities, Activities) versus ERP-layer tables (invoices, accounting, payroll). We extract the field registry to capture all custom field names, types, and object assignments. We also pull pipeline and stage configuration to map TeamSystem's deal stages to Nutshell's stage structure. The discovery output is a written data separation map and a CRM-layer-only export specification.
Data quality review and cleanup

We run a data quality assessment on the extracted CRM-layer records. This includes identifying duplicate contacts (same email, different records), incomplete fields (missing owner assignment, missing company linkage), and inconsistent formats (phone number formatting, address fields split across columns). We deliver a cleanup checklist to the customer before migration runs so that the source data entering Nutshell is deduplicated and standardized.
Nutshell environment setup

We configure the Nutshell destination before any data loads. This includes creating the Organization and Person field schema (including any custom fields matched from the TeamSystem field registry), configuring Deal stages to match the TeamSystem pipeline structure, setting up loss and win reason picklists, and provisioning user accounts for all active TeamSystem owners. User provisioning requires the customer to create Nutshell accounts for each owner before the migration run begins.
Sample migration and reconciliation

We run a test migration with a representative subset (typically 100-500 records per object) into a staging phase within Nutshell. The customer reviews the mapped records, confirms that field values appear in the correct Nutshell fields, verifies that Person-to-Organization linking is accurate, and validates deal stage assignments. Any mapping corrections are applied to the full migration specification before the production run begins.
Full production migration

We execute the full migration in dependency order: Organizations (Companies first so that Person-to-Org linkage is satisfied), People (Contacts with OrganizationId resolved), Leads (with status mapped), Deals (with stage, owner, and linked Organization resolved), and Activities (with timestamp and owner preserved). Each phase emits a row-count reconciliation report. Any records that fail validation (missing required fields, type mismatch) are held in a correction queue for the customer to resolve before re-import.
Cutover and post-migration handoff

We freeze writes in TeamSystem during the cutover window, run a final delta migration of any records modified during the final days before cutover, and confirm that Nutshell is the system of record. We deliver the workflow inventory document and the integration handoff checklist to the customer's admin. We support a 72-hour hypercare window to resolve any data issues surfaced by the sales team after go-live.
