How long does a Contractor+ to Mailchimp migration take?

Small migrations with fewer than 2,500 contacts complete within 4–8 hours of clock time. Medium-sized datasets of up to 10,000 contacts typically require 1–2 business days. Larger datasets over 10,000 contacts, or those with 15+ merge fields and financial data requiring encoding, extend to 3–5 days. The main variables are the number of custom fields that need mapping and the amount of data cleanup required before import.

Will my Contractor+ workflows migrate to Mailchimp Customer Journeys?

No. Contractor+ workflows such as estimate approval chains, payment reminder sequences, and job scheduling notifications cannot migrate to Mailchimp because the two platforms use fundamentally different automation models. We export your workflow definitions as a reference document so your team or our implementation team can rebuild equivalent Customer Journeys in Mailchimp.

What happens to my Contractor+ financial data (estimates and invoices) in Mailchimp?

Contractor+ estimates and invoices have no native equivalent in Mailchimp. Estimate ID, amount, status, and due date migrate as custom merge fields on each client contact. Invoice totals, status, and payment dates similarly migrate as merge fields. Line items from estimates are JSON-encoded into a text merge field, subject to Mailchimp's 255-character limit per field.

Can I migrate Contractor+ custom fields to Mailchimp?

Yes, custom fields from Contractor+ migrate to Mailchimp merge fields or contact tags, subject to two constraints. Each Mailchimp audience is limited to 30 merge fields, and each merge field is capped at 255 characters. We audit your full custom-field list before migration and prioritize the highest-value fields, flagging any that exceed limits or must be deferred.

Does Contractor+ track unsubscribes, and how do I handle them in Mailchimp?

Contractor+ does not natively track unsubscribes or do-not-contact flags. If any clients in your Contractor+ database were marked as do-not-email outside the platform, that list must be provided separately before migration. We import any provided suppression list into Mailchimp's suppression management to prevent accidental sends to those contacts.

Does the migration affect my Contractor+ account during the cutover?

No. We use read-only export access on Contractor+ — your team continues working in Contractor+ throughout the migration window. A final delta sync captures any records modified between the initial export and go-live. There is no downtime and no risk of data corruption in Contractor+ during the migration.

What happens to Mailchimp field labels after migration?

Since Contractor+ and Mailchimp use completely different field-naming conventions, Mailchimp field labels will not match Contractor+ field names exactly. For example, Contractor+'s client_status becomes a Mailchimp tag rather than a labeled field, and financial amounts become custom merge fields with __c-suffixed names. We provide a full field-mapping document that lists every source field, its Mailchimp destination, and the transformation applied, so your team can interpret Mailchimp data in its original business context.

Contractor+ to Mailchimp Migration — Field-Level Mapping & Rollback

Overview

What this migration involves

Contractor+ is a job-management CRM built around client records, estimates, invoices, and scheduling for field-service businesses. Mailchimp is an email marketing platform organized around audiences, contacts, tags, merge fields, and campaigns — it has no concept of jobs, estimates, or invoices. This migration translates CRM data into Mailchimp's flat contact model: clients become audience members, trade type and payment status become tags for segmentation, and estimate amounts, invoice totals, and line items encode into Mailchimp merge fields. The main translation challenges are Mailchimp's 255-character merge-field limit for notes, the absence of a native unsubscribe-tracking equivalent for Contractor+ contacts, and the fact that workflows and automations cannot migrate and must be rebuilt. We sequence the migration via CSV export from Contractor+, data transformation, and batched import into Mailchimp with merge-field mapping and tag application at each step.

Why teams make this switch

Two sides of the same decision

Leaving

Contractor+

What's pushing teams away

The subcontractor management feature was repeatedly delayed past its promised release date, frustrating users who needed to create accounts and assign work to sub-contractors.
Client Portal lacks granular visibility controls — users cannot hide specific job types or data that do not apply to a particular client, creating confusion and information disclosure risk.
Freedom plan caps estimates and invoices at 5 per month, forcing contractors to upgrade to Pro sooner than expected as soon as they start taking on regular work.
Users report a learning curve when first exploring the system — creating test quotes, jobs, and invoices takes a few evenings to feel comfortable, and the initial onboarding lacks guided structure.
The platform is relatively new and rapidly evolving, meaning features available at evaluation may shift or be removed before sub-ecosystems (like the subcontractor portal) are fully built out.

Choosing

Mailchimp

What's pulling them in

Generous free tier with up to 500 contacts allows small teams to validate email marketing before committing to a paid plan.
Intuitive drag-and-drop email builder and 130+ templates let non-technical users produce professional campaigns without HTML or CSS knowledge.
300+ native integrations, especially Canva and Shopify, make it easy to connect existing tools without custom development work.
Detailed open-rate, click-through, and campaign analytics give small businesses actionable insights without a dedicated marketing team.
One-platform consolidation of email campaigns, automations, landing pages, and ads reduces tool sprawl for lean marketing teams.

Object mapping

How Contractor+ objects map to Mailchimp

Each row shows how a Contractor+ object lands in Mailchimp, including any object-level transformations, lookup resolution, or schema-design dependencies.

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

Contractor+

Client

maps to

Mailchimp

Mailchimp Audience / Member

1:1

Fully supported

Each Contractor+ client becomes a single Mailchimp audience member. Contact name, email address, phone number, and physical address map directly. Client status and trade type do not have native Mailchimp fields — they translate to tags for segmentation and filtering.

Contractor+

Client Status

maps to

Mailchimp

Contact Tag

1:1

Fully supported

Contractor+ client statuses (active, paused, completed) have no native Mailchimp field. We map each status value to a Mailchimp tag applied at import time. Tags enable segmentation in Mailchimp's built-in audience filtering without requiring custom fields.

Contractor+

Trade Type

maps to

Mailchimp

Contact Tag

1:1

Fully supported

Trade type (electrical, plumbing, HVAC, etc.) stored as a Contractor+ client property. In Mailchimp this maps to a contact tag, since no native trade-type field exists. Tags support multiple values per contact, matching Contractor+'s multi-trade support.

Contractor+

Estimate

maps to

Mailchimp

Custom Merge Fields

1:1

Fully supported

Contractor+ estimates are standalone objects with amount, status, and line items. Mailchimp has no estimate object — estimate ID, amount, status, and dates migrate as custom merge fields (EST_AMOUNT__c, EST_STATUS__c). Line items, which may contain multiple rows, are JSON-encoded into a single merge field.

Contractor+

Estimate Line Item

maps to

Mailchimp

JSON Text in Merge Field

1:1

Fully supported

Estimate line items include item description, quantity, unit cost, and subtotal. Mailchimp has no line-item structure, so we JSON-encode the full line-item set and store it in a custom merge field. Note: Mailchimp limits merge fields to 255 characters, so long line-item sets may require truncation or splitting across two fields.

Contractor+

Invoice

maps to

Mailchimp

Custom Merge Fields

1:1

Fully supported

Invoice ID, amount, status, issue date, due date, and payment info migrate as custom merge fields (INV_AMOUNT__c, INV_STATUS__c, INV_PAID_DATE__c). Invoice status values (paid, partial, overdue) map to specific text values for reporting continuity.

Contractor+

Client Note

maps to

Mailchimp

Custom Merge Field (TEXT)

1:1

Fully supported

Contractor+ notes attached to client records migrate as a custom text merge field. Mailchimp's merge-field limit is 255 characters; notes exceeding this length are truncated with a marker and the full text preserved in a companion field if a second merge field is available.

Contractor+

Contract Amount

maps to

Mailchimp

Custom Merge Field (NUMBER)

1:1

Fully supported

The agreed contract value from Contractor+ becomes a custom number merge field in Mailchimp (CONTRACT_VALUE__c). This enables revenue-tiered segmentation and reporting within Mailchimp campaigns without needing a separate CRM lookup.

Contractor+

Payment Status

maps to

Mailchimp

Contact Tag

1:1

Fully supported

Payment statuses from Contractor+ invoices (paid, partial, overdue) map to Mailchimp tags (payment_paid, payment_partial, payment_overdue). Tags are applied at migration time and can be updated via Mailchimp automations as payments are received post-migration.

Contractor+

Client Source / Referral

maps to

Mailchimp

Custom Merge Field (TEXT)

1:1

Fully supported

How the client was acquired (referral, lead form, repeat client) stored as a text merge field in Mailchimp (CLIENT_SOURCE__c). Supports source-based segmentation for targeted re-engagement campaigns.

Contractor+

Contractor+ Object ID

maps to

Mailchimp

Custom Merge Field (TEXT)

1:1

Fully supported

The original Contractor+ record ID is stored as a custom merge field (SRC_SYSTEM_ID__c) on each Mailchimp contact. This enables traceability back to the source system and supports delta-run deduplication if a second migration pass is needed.

Contractor+

Unsubscribes / Do-Not-Email

maps to

Mailchimp

Mailchimp Suppression List

1:1

Fully supported

Contractor+ does not natively track unsubscribes or do-not-contact flags. If any clients were marked as do-not-email in Contractor+, that list must be provided separately and imported to Mailchimp's suppression list before any campaigns send. We flag this gap in the pre-migration audit.

Pair-specific challenges

Mailchimp's 30-field audience limit may require field triage

Mailchimp caps each audience at 30 merge fields. Contractor+ clients with multiple estimates and invoices can generate 15+ fields (EST_AMOUNT__c, INV_AMOUNT__c, EST_STATUS__c, INV_STATUS__c, and more). We audit the full field list before migration and prioritize the highest-value fields. Lower-priority financial fields can be stored as a single JSON block or deferred to a reference document rather than individual merge fields.
Merge-field 255-character limit truncates long client notes

Contractor+ client notes can run to multiple paragraphs of text. Mailchimp merge fields are capped at 255 characters. Notes exceeding this limit are truncated at 255 characters with a truncation marker appended. The full note text is preserved in a companion merge field if a second slot is available, or flagged for manual retrieval from the Contractor+ export file.
Contractor+ does not track unsubscribes natively

Unlike HubSpot or Salesforce, Contractor+ has no built-in unsubscribe or do-not-contact flagging system. If any clients were marked as do-not-email outside the platform, that list must be provided separately. We import any provided suppression list into Mailchimp's suppression management before the first campaign send, and we flag this as a pre-migration compliance requirement.
Estimate and invoice data has no native Mailchimp equivalent

Contractor+ stores estimates and invoices as full objects with line items, tax rates, and payment schedules. Mailchimp has no object model for these — they must be encoded as JSON text within merge fields. Line items with many rows may exceed the 255-character limit and require splitting across multiple fields. We document every encoding decision in the field-mapping spec before migration runs.
Automations and workflows must be rebuilt from scratch

Contractor+ workflows such as estimate approval chains, payment reminder sequences, and job-scheduling notifications have no equivalent in Mailchimp. Mailchimp's Customer Journey builder can recreate campaign-oriented automations (welcome sequences, follow-up campaigns, re-engagement drips), but the logic must be rebuilt by your team or our implementation team using the exported workflow definitions as a reference document.

Migration approach

Six steps for a successful Contractor+ to Mailchimp data migration

Export Contractor+ data and audit field coverage

We extract all client records, estimates, invoices, and associated custom fields from Contractor+ via CSV export or API. We audit the full field list against Mailchimp's 30-merge-field audience limit, flagging any fields that will require truncation, splitting, or exclusion. We also ask for any do-not-contact lists that may exist outside the platform for suppression-list import.
Design Mailchimp merge-field schema and tag strategy

Based on the field audit, we design the Mailchimp merge-field schema: which fields become native merge fields, which become tags, and which financial objects (estimates, invoices) are encoded as JSON text. We deliver a field-mapping spec showing the Mailchimp field name, type, and any transformation note for each source field before migration begins.
Transform data and run a test batch import

We transform the exported data into Mailchimp's import format, applying tag assignments, merge-field encoding, and JSON serialization for financial fields. A test batch of up to 100 contacts imports first to verify field mapping, tag application, and character-limit compliance. You review the test batch in Mailchimp before the full migration proceeds.
Import remaining contacts in batches and apply suppression list

The remaining contacts import in Mailchimp-compliant batches of up to 5,000 records per batch. Any unsubscribes or do-not-contact entries identified in Step 1 are imported to Mailchimp's suppression list before the first campaign send. Tags and merge fields apply at import time based on the field-mapping spec from Step 2.
Final delta sync and go-live

A final sync captures any records modified in Contractor+ between the initial export and the cutover window. We run a reconciliation check comparing record counts and a spot-check of merge-field values in Mailchimp against the source export. Once verified, your team can begin using Mailchimp for campaigns and automations. We provide the full field-mapping documentation and exported workflow definitions for rebuilding automations in Mailchimp Customer Journeys.
