Overview

What this migration involves

Moving from Wice CRM to Nutshell requires working around Wice's absence of a documented public API, which makes this migration CSV-driven rather than API-driven. We extract Contacts, Organizations, Deals, Projects, and Tasks from Wice's built-in CSV export, then write them to Nutshell in dependency order: Organizations first, then Contacts with the resolved Account reference, then Deals with the resolved Person and Account lookups, then the project and task hierarchy. Wice's category system does not map 1:1 to Nutshell's tag model; we export category assignments as a multi-value text field and let the customer decide whether to configure them as Nutshell tags post-import. Custom pipeline stages require an explicit stage-mapping table generated during discovery. Hold files (attachments), workflows, campaigns, reports, and dashboard configurations do not migrate; we deliver a written inventory of these elements for the customer to rebuild in Nutshell. Nutshell's JSON-RPC API with Basic auth and per-domain API tokens drives the destination write, with rate-limit handling on find requests and bulk insert support for CSV-derived records.

Why teams make this switch

Two sides of the same decision

Leaving

Wice CRM logo

Wice CRM

What's pushing teams away

  • Search functionality fails to return results reliably, forcing users to navigate manually through contacts and deals which becomes time-consuming at scale.
  • Document exports do not convert cleanly to Microsoft Office formats, disrupting workflows that depend on shared editable files.
  • The budget-tracking module lacks depth, pushing finance-focused teams toward ERPs or CRMs with richer reporting for revenue forecasting.
  • Dashboard display occasionally renders incorrectly, creating inconsistent visibility into pipeline stages and upcoming activities.

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 Wice CRM objects map to Nutshell

Each row shows how a Wice 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.

Wice CRM

Organization

maps to

Nutshell

Company

1:1
Fully supported

Wice Organizations map to Nutshell Companies. Wice enforces that Contacts must be linked to an Organization, so we export Organizations first and use the Wice Organization ID as the dedupe key during Nutshell Company import. Company name, address fields, phone, and website migrate directly. Any Organization without a name is flagged for the customer to name before import.

Wice CRM

Contact

maps to

Nutshell

Person

1:1
Fully supported

Wice Contacts map to Nutshell People. We resolve the parent Organization to a Nutshell Company by name or ID match during the Contact export phase, then set the AccountId lookup on each Person record. Name, email, phone, title, and address fields migrate directly. Custom contact properties (Gold tier on Wice) map to Nutshell custom fields on People; we create the Nutshell custom fields before import begins.

Wice CRM

Deal

maps to

Nutshell

Deal

1:1
Fully supported

Wice Deals map to Nutshell Deals with the Person (Contact) and Company (Organization) lookups resolved at migration time. Wice allows fully custom pipeline stages per installation, so we capture the actual Wice stage names during discovery and generate a stage-mapping table before any Deal records are written to Nutshell. Deal value, expected close date, and owner assignment migrate directly.

Wice CRM

Deal Stage

maps to

Nutshell

Deal Stage

lossy
Fully supported

Each distinct Wice pipeline stage becomes a Nutshell Deal stage value. We configure the Nutshell Deal stages in the account settings before migration, matching Wice stage names to Nutshell stage names chosen by the customer. Stage mapping errors are the most common cause of deal-value misrepresentations post-migration, so we validate the stage table with the customer's sign-off before any Deal writes begin.

Wice CRM

Project

maps to

Nutshell

Milestone or Task grouping

1:many
Fully supported

Wice Projects contain Tasks and custom fields. We export Projects as Nutshell Milestones if the customer uses Nutshell's milestone feature, or we export the project name as a Nutshell tag on the child tasks to preserve grouping. Project-level custom fields map to custom fields on the related tasks. Orphan tasks (not inside a project) export as standalone Nutshell tasks.

Wice CRM

Task

maps to

Nutshell

Task

1:1
Fully supported

Wice Tasks live inside Projects or standalone linked to contacts or deals. We export both contexts. Standalone tasks linked to a Contact map to Nutshell Tasks with the Person lookup resolved. Tasks inside a project inherit the project tag or milestone grouping. Task status, priority, due date, and assignee (owner) migrate directly. Orphaned tasks are flagged for customer review before import.

Wice CRM

Campaign

maps to

Nutshell

Tag or Note

lossy
Fully supported

Wice differentiates basic and advanced campaigns. We export campaign names and targeting properties as a text property or Nutshell tag on the related Contact and Deal records. Campaign history (sent/open/click data) does not export from Wice and cannot be migrated. The customer rebuilds campaign tracking in Nutshell or a dedicated marketing platform post-migration.

Wice CRM

Ticket

maps to

Nutshell

Person Note or Tag

lossy
Fully supported

Wice Tickets linked to contacts or organizations map to Nutshell Notes attached to the corresponding Person record, with a ticket status tag applied. Wice custom ticket fields map to custom fields on the Note or to Nutshell People custom fields at the customer's choice. Ticket numbering sequences reset in Nutshell; we document the original Wice ticket numbers in a custom field for reference.

Wice CRM

Note

maps to

Nutshell

Note

1:1
Fully supported

Wice free-text notes attached to contacts, organizations, deals, and projects migrate to Nutshell Notes linked to the corresponding Person, Company, or Deal record. Note body migrates as plain text. Wice formatting (bold, lists) may be simplified. We preserve the source-object linkage so notes remain findable in context.

Wice CRM

Category

maps to

Nutshell

Tag or Multi-value Text

lossy
Fully supported

Wice uses a category system for deduplication and classification that does not map 1:1 to Nutshell's tag model. We export category assignments as a comma-separated text field or map to Nutshell tags if the customer chooses. The customer decides during scoping whether to use tags (actionable) or text fields (audit-only) for the category mapping.

Wice CRM

Custom Property

maps to

Nutshell

Custom Field

lossy
Fully supported

Wice custom fields on contacts, organizations, deals, and projects (Gold tier) map to Nutshell custom fields on People, Companies, and Deals. Picklist-style custom fields require value translation if the destination picklist values differ. We create Nutshell custom fields before import begins so that CSV imports map to the correct field IDs.

Pair-specific challenges

  • Wice CRM has no public API — migration is CSV-driven

    Wice CRM does not publish a REST API or developer documentation. All migration paths from Wice rely on the built-in CSV export function for cloud installations or direct database access for on-premise deployments. We request the customer to export contacts, organizations, and deals through Wice's UI export, and we process those exports into Nutshell. For on-premise customers with database access, we can query the underlying tables directly for a more complete dataset including relationship IDs. This constraint means the migration runs in batch mode rather than real-time sync, and any post-export changes in Wice require a delta export before go-live.

  • Hold files (attachments) require a separate file-level export

    Wice stores attachments as Hold files attached to records but provides no bulk download mechanism. During migration scoping, we flag every record with attachments and provide the customer with a file-level export checklist. Each attachment must be downloaded individually through the Wice UI or via a custom script for on-premise installations. We can stage the files and import them into Nutshell's attachment system post-migration, but the file retrieval step is manual and time-intensive. This step should be budgeted separately from the record migration.

  • Custom Wice pipeline stages require explicit stage mapping

    Wice allows full customization of pipeline stages per installation. A deal that sits in stage 'Angebot gesendet' in a German-language Wice installation might need to map to 'Negotiation' in Nutshell's default stage set. We capture the customer's actual Wice stage names during discovery, generate a stage-mapping table with customer sign-off, and configure Nutshell stages before any Deal records are written. Stage mapping errors are the most common cause of deal-value misrepresentations post-migration and require a manual correction run if missed.

  • Nutshell custom fields must be created before import

    Nutshell requires custom fields to exist in the account before import files can map to them. We define all Nutshell custom fields for People, Companies, and Deals during the schema configuration step before any CSV import begins. This prevents hours of cleanup work later. We coordinate with the customer to confirm field names, types, and picklist values during the discovery phase.

  • Workflows, automations, reports, and dashboards do not migrate

    Wice workflows, campaign automations, saved reports, and dashboard chart configurations are configuration-based and do not export as data. We deliver a written inventory of every active Wice workflow, automation, and saved report with its trigger, conditions, and recommended Nutshell equivalent. The customer's admin rebuilds these in Nutshell post-migration. Nutshell Workflows (available on Pro and above) offer CRM-task automation but differ structurally from Wice's module-based workflow logic and require a separate configuration effort.

Migration approach

Six steps for a successful Wice CRM to Nutshell data migration

  1. Discovery and export scoping

    We audit the source Wice installation to identify record counts for contacts, organizations, deals, projects, tasks, tickets, and notes. For cloud installations, we request the customer to run Wice's built-in CSV export for each object type and share the files via a secure transfer. For on-premise installations, we request database access or a database export so we can retrieve the full relationship graph including Contact-to-Organization IDs. We also document Wice's custom pipeline stages, custom fields, and category assignments during this phase.

  2. Schema design and Nutshell custom field creation

    We create the Nutshell custom fields for People, Companies, and Deals before any data import. This includes mapping Wice custom properties to typed Nutshell fields (text, number, date, picklist), configuring the Nutshell Deal stages to match the Wice stage names from the discovery phase, and setting up any picklist values required for migrated custom fields. We configure stage mapping with customer sign-off before moving to import.

  3. Attachment inventory and file export checklist

    We flag every Wice record with Hold file attachments and generate a file-level export checklist for the customer. The customer downloads attachments individually from Wice's UI or scripts the download for on-premise installations. We stage the exported files for re-upload to Nutshell post-migration. Attachment export is the most time-intensive manual step and should run in parallel with the record migration to avoid blocking go-live.

  4. Test migration and reconciliation

    We run a test migration into a Nutshell sandbox or trial account using the exported CSV files. We validate record counts (Organizations in, People in, Deals in, Tasks in), spot-check 20-30 records against the Wice source for field accuracy, and confirm that the Contact-to-Organization relationship resolves correctly. Any mapping corrections happen in the test phase before production migration begins.

  5. Production migration in dependency order

    We run production migration in dependency order: Companies (from Wice Organizations) first, then People (with AccountId resolved), then Deals (with PersonId and AccountId resolved), then Tasks (with Person or Deal lookups resolved), then Notes. Each phase emits a row-count reconciliation report before the next phase begins. CSV files are written via Nutshell's import API with batch chunking to handle record volumes efficiently.

  6. Cutover, validation, and automation inventory delivery

    We freeze Wice writes during cutover, run a final delta export of any records modified during the migration window, then mark Nutshell as the system of record. We deliver the written inventory of Wice workflows, automations, reports, and dashboard configurations for the customer's admin to rebuild in Nutshell. We support a one-week hypercare window where we resolve any data quality issues raised by the team. We do not rebuild Wice workflows or automations as Nutshell Workflows inside the migration scope; that is a separate configuration engagement.

Most migrations land between three and five weeks for accounts under 5,000 Contacts, 2,000 Organizations, and 1,000 Deals with no custom objects or high attachment volumes. Migrations with large project hierarchies, significant attachment counts, complex custom field schemas, or multi-stage custom pipeline stages move to six to ten weeks because of manual attachment handling, stage-mapping iteration, and Nutshell schema configuration time.
