Overview

What this migration involves

Spark CRM stores contacts as People, companies separately, and supports Leads alongside a deal-tracking pipeline model. Nutshell mirrors this structure with People, Companies, Leads, and Deals — but uses a simpler stage-based pipeline without record-type complexity. The migration carries all standard fields (names, emails, phones, addresses) as direct mappings, while Spark custom fields migrate as Nutshell custom fields on their respective record types. Deal amounts, stage names, and close dates map value-by-value, though Spark's pipeline stage probability weights require manual re-entry in Nutshell. Activity history (notes, tasks, completed activities) migrates as Nutshell Activities linked to the parent record. Nutshell's marketing contact model differs from Spark's — there is no equivalent billing flag, so this data is preserved as a reference custom field. Workflows, sequences, and automation logic do not transfer; FlitStack exports Spark workflow definitions as a rebuild reference for your Nutshell admin. To ensure data integrity, the migration runs a pre-check of field-level mapping, a sample diff on a subset of records, and a delta-pickup window that captures any changes made in Spark CRM during cutover, delivering a complete and accurate dataset in Nutshell at go‑live.

Why teams make this switch

Two sides of the same decision

Leaving

Spark CRM

What's pushing teams away

  • Limited independent customer review footprint — vendor relies on self-published claims (e.g., 'instantly boost ROI by 87%') rather than third-party validation.
  • Pricing transparency is partial — Business plan at $199/month plus 1.5% platform fees published, but other tiers/limits are not fully disclosed, surprising operators as transaction volume scales.
  • Confusion with the unrelated Spark CRM real-estate product (spark.re) and other 'Spark' branded CRM platforms creates procurement friction.
  • No specific implementation timeline or support structure published, making delivery risk hard to scope for buyers.
  • Payment-orchestration-first positioning may not suit teams seeking a general-purpose CRM, since the value prop is tightly tied to transaction approval rates.

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 Spark CRM objects map to Nutshell

Each row shows how a Spark 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.

Spark CRM

Person

maps to

Nutshell

Person

1:1
Fully supported

Spark CRM People map directly to Nutshell People. Standard fields (name, email, phone, address) migrate as direct mappings. The primary Company association becomes the Nutshell Person's Company link. Owner resolution happens via email match to Nutshell users before records commit.

Spark CRM

Company

maps to

Nutshell

Company

1:1
Fully supported

Spark CRM Companies map directly to Nutshell Companies. Company name, domain/website, industry, employee count, and annual revenue transfer as direct or value‑mapped fields. Parent‑company hierarchies in Spark become Parent Company links in Nutshell where supported. The mapping also includes phone number, address, and any custom fields on the Company object. We resolve any duplicate company names by appending a numeric suffix.

Spark CRM

Lead

maps to

Nutshell

Lead

1:1
Fully supported

Spark CRM Leads map to Nutshell Leads without transformation. Lead status, source, and any custom fields migrate to Nutshell Lead custom fields. Unconverted Spark Leads (status 'open') land as active Nutshell Leads ready for follow‑up assignment. We also preserve the original lead creation date and owner email for audit trail purposes.

Spark CRM

Deal

maps to

Nutshell

Deal

1:1
Fully supported

Spark CRM Deals map to Nutshell Deals with stage name value-mapping. Deal name, amount, close date, and owner transfer directly. Pipeline association in Spark maps to Nutshell's single-pipeline model; if Spark uses multiple pipelines, each becomes a separate Deal category or tag in Nutshell.

Spark CRM

Activity (Call, Email, Meeting)

maps to

Nutshell

Activity

1:1
Fully supported

Spark CRM activity records (calls logged, emails tracked, meetings scheduled) become Nutshell Activities attached to the corresponding Person, Company, or Deal. Activity type, subject, date/time, duration, and outcome notes transfer. Owner preserves as the activity creator. If an activity references a contact that hasn't been migrated yet, we queue it for later attachment after the contact is created.

Spark CRM

Note

maps to

Nutshell

Activity (Note type)

1:1
Fully supported

Spark CRM Notes attached to People, Companies, or Deals migrate as Nutshell Activities with type 'Note'. Rich‑text formatting in Spark Notes is preserved as plain text or HTML in Nutshell Activity notes, depending on the source format. Any embedded images or file links are converted to attachment references or stored as URLs for convenient access.

Spark CRM

Custom Field (Person)

maps to

Nutshell

Custom Field (Person)

1:1
Fully supported

Spark CRM custom fields on People require pre-creation of matching Nutshell Person custom fields before migration. Field types (text, number, date, picklist) are preserved. Picklist values are mapped value-by-value; any values without Nutshell counterparts are flagged for admin review before the full run.

Spark CRM

Custom Field (Company)

maps to

Nutshell

Custom Field (Company)

1:1
Fully supported

Spark CRM company custom fields (e.g., industry‑specific identifiers, account numbers) migrate to Nutshell Company custom fields. Nutshell's per‑object custom field limits apply; most SMB plans accommodate 20+ custom fields per object type. We also map any pick‑list values to Nutshell's pick‑list options, flagging mismatches for manual review.

Spark CRM

Custom Field (Deal)

maps to

Nutshell

Custom Field (Deal)

1:1
Fully supported

Spark CRM Deal custom fields (e.g., deal type, product line, renewal date) map to Nutshell Deal custom fields. These fields are available for reporting and filtering in Nutshell's Deal view after migration completes. If a custom field uses a dependent pick‑list, we preserve the dependency structure to the extent Nutshell supports it.

Spark CRM

Attachment / File

maps to

Nutshell

File Attachment

1:1
Fully supported

Spark CRM file attachments on People, Companies, or Deals are re‑uploaded to Nutshell as file attachments on the corresponding record. File size limits apply per Nutshell's attachment constraints. We verify file integrity (MD5 checksum) before and after upload. We also retain the original file name and creation timestamp to preserve context.

Spark CRM

Owner / User

maps to

Nutshell

User

1:1
Fully supported

Spark CRM owner assignments on records resolve to Nutshell users via email address match. Unmatched owners are flagged before migration; your team either creates Nutshell user accounts for them or assigns records to a fallback owner before the full run commits.

Spark CRM

Workflow / Automation

maps to

Nutshell

Not Migrated

1:1
Fully supported

Spark CRM workflows, sequences, and automation rules do not migrate. They are exported as a structured JSON document describing triggers, conditions, and actions so your Nutshell admin can rebuild equivalent logic using Nutshell's workflow builder or third‑party automation tools. The JSON includes field names, operator types, and expected values for each step, facilitating accurate reconstruction.

Pair-specific challenges

  • Spark CRM pipeline stage probability weights do not transfer to Nutshell

    Spark CRM allows custom probability percentages per pipeline stage, giving sales teams forecast accuracy that feeds into revenue planning. Nutshell's Deal stages use a simpler model where probability is entered manually per Deal or set as default percentages per stage. We map the stage names correctly, but probability percentages require manual re-entry in Nutshell after migration. Your sales ops team should review each pipeline's stage probabilities before go-live to ensure forecast accuracy is maintained.

  • Spark CRM marketing contact billing flag has no Nutshell equivalent

    Spark CRM's pricing tiers on lower plans meter contacts differently, distinguishing between marketing-billable contacts and CRM-only records. Nutshell does not have a comparable billing flag — all contacts on a paid plan are treated equally for CRM purposes, and marketing contacts are a separate priced add-on (email marketing). We preserve the original Spark contact billing classification as a custom field (Spark_Marketing_Contact__c) for reference, but Nutshell's contact economics are independent of this value.

  • Multi-company associations on Spark People collapse to primary Company in Nutshell

    Spark CRM supports linking a single Person record to multiple Company records through N:N associations. Nutshell's Person-to-Company relationship uses a single primary Company lookup. We migrate the most-recently-modified company association as the primary Company link and surface additional company associations as a custom field (Secondary_Companies__c) for admin review. If your team relies on seeing all associated companies on a single Person record, this secondary field requires manual consolidation or a custom junction object.

  • Spark CRM custom field API returns grouped metadata that requires parsing

    Spark CRM's Custom Fields API returns field definitions grouped by field group, with field types, pick‑list options, and required flags nested in the response structure. Nutshell's custom field creation API accepts flat field definitions per object type. We extract field definitions from Spark's grouped metadata and flatten them into Nutshell‑compatible field creation payloads. Custom field ordering within Nutshell's UI follows the order of creation or priority, not the Spark group order.

  • Spark CRM email integration settings do not transfer to Nutshell's email sync

    If Spark CRM is connected to email accounts for tracking (e.g., Gmail or Outlook integration for email logging against contacts), those OAuth connections and sync settings are platform‑specific and do not carry over. Nutshell requires re‑authenticating email accounts in its own integration settings. We document the connected email accounts from Spark so your admin knows which accounts need reconnection in Nutshell before email logging resumes. Additionally, we provide a checklist of required permissions for each email provider to streamline the re‑authentication process.

Migration approach

Six steps for a successful Spark CRM to Nutshell data migration

  1. Extract Spark CRM data via API and assess schema

    FlitStack AI connects to Spark CRM using your API credentials and pulls a full export of People, Companies, Leads, Deals, Activities, and custom field definitions. We parse the custom field metadata (group structure, field types, pick-list values) and generate a pre-migration schema report showing which fields map directly, which need value mapping, and which require Nutshell custom field pre-creation. This report is the planning artifact your admin uses to configure Nutshell before the migration run.

  2. Pre-create Nutshell custom fields and validate owner accounts

    Before data moves, your Nutshell admin (or our team acting with admin credentials) creates the custom fields identified in the schema report on the correct object types (People, Companies, Leads, Deals). We cross-check Spark CRM owner email addresses against Nutshell user accounts — unmatched owners are flagged with the account email so your team can create Nutshell users or reassign ownership before the migration commits records.

  3. Migrate Companies and People first to preserve lookup integrity

    Nutshell requires Company records to exist before People can link to them via the Company lookup. We sequence the migration so Companies load first with their custom fields, followed by People with direct field mappings and Company resolution. Leads and Deals load after People, with foreign keys resolving to the correct Company and Person records. This load order prevents orphan records and broken lookup relationships in Nutshell.

  4. Run sample migration with field-level diff

    A representative sample (typically 200–500 records spanning People, Companies, Deals, and Activities) migrates first. We generate a field-level diff comparing source values against destination values for every mapped field, plus a record-count reconciliation showing total People, Companies, Deals, and Activities that will transfer. You review the diff and confirm mappings before the full run is approved. This validation step catches value-mapping gaps and custom field misconfigurations before they affect production data.

  5. Execute full migration with delta-pickup window

    After sample approval, the full migration runs against Nutshell's API. A delta-pickup window (24–48 hours) captures any records created or modified in Spark CRM during the cutover period, ensuring Nutshell reflects Spark's final state at go-live. All operations are logged in an audit trail. If reconciliation fails, one-click rollback reverts the Nutshell instance to its pre-migration state. After rollback verification, the migration can be re-run with corrected mappings.
