Overview
Trade Service Pro organizes field service operations around customers, locations, work orders, jobs, and invoices — a job-centric data model built for dispatch, scheduling, and billing workflows. Mailchimp's data model is fundamentally different: the primary entity is the subscriber, and everything else — custom fields, tags, segments, and automations — exists to support email marketing campaigns. FlitStack AI migrates the contact and customer layer from Trade Service Pro into Mailchimp's audience structure. Names, email addresses, phone numbers, and physical addresses map to Mailchimp's standard subscriber fields. Trade-service-specific fields — service history, equipment types, work-order status, technician assignments, and invoice data — get encoded as Mailchimp custom fields and tags so your team can filter and segment on operational context post-migration. Work orders, scheduling, invoicing logic, and field-service automations have no native equivalent in Mailchimp and must be rebuilt manually. The migration mechanism uses a CSV export from Trade Service Pro mapped into Mailchimp's import format — no write-access required to Trade Service Pro during cutover, with a 24-48 hour delta window capturing in-flight changes.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Trade Service Pro 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.
Trade Service Pro
Customer / Contact
Mailchimp
Subscriber
1:1Trade Service Pro customer records map 1:1 to Mailchimp subscribers. Names, emails, and phone numbers map to Mailchimp standard fields. One customer record = one subscriber in the Mailchimp audience. Additionally, any custom fields on the customer record—such as industry, service type, or account status—will be mapped to Mailchimp custom merge fields or tags, ensuring all relevant context transfers for segmentation.
Trade Service Pro
Contact Phone
Mailchimp
Subscriber Phone
1:1Mobile phone and office phone from Trade Service Pro map to Mailchimp's PHONE merge field. Both numbers can be stored if the phone field captures mobilephone specifically. If both mobile and office numbers are present, the primary (mobile) goes in PHONE, and the secondary is stored as a custom text field (Office_Phone__c) for SMS and call reference.
Trade Service Pro
Location / Address
Mailchimp
Subscriber Address
many:1Trade Service Pro location address, city, state, and ZIP are merged into Mailchimp's structured ADDRESS field (ADDR1, CITY, STATE, ZIP). Country is added as available. Addresses get stored as-is; Mailchimp does not validate deliverability. If a customer has multiple locations, the primary address is used for ADDRESS, and additional locations are stored as custom fields (e.g., Location2__c) for reference. Incomplete addresses are flagged for manual review before import.
Trade Service Pro
Company / Business Name
Mailchimp
Subscriber COMPANY
1:1The primary business or company name on the Trade Service Pro customer record maps to Mailchimp's COMPANY merge field. Useful for B2B segmentation and company-based campaign targeting. If a contact is linked to multiple companies, the primary company name is stored in COMPANY, while secondary affiliations are captured as custom fields (e.g., Secondary_Company__c) or tags for multi-entity segmentation. This preserves the hierarchy without duplicating subscriber records.
Trade Service Pro
Work Order
Mailchimp
Subscriber Custom Field
1:1Work order records have no native Mailchimp equivalent. Work-order name, description, amount, and dates are encoded as custom merge fields on the subscriber record. Job status (PENDING, COMPLETED, INVOICED) maps as a tag for quick filtering. Each work order includes a reference ID stored as a custom field (Work_Order_ID__c) for traceability, and tags are applied in lowercase (pending, completed, invoiced) to match Mailchimp conventions.
Trade Service Pro
Job / Service Record
Mailchimp
Subscriber Custom Field + Tag
1:1Service history, technician assignments, and scheduled dates have no Mailchimp equivalent. These get encoded as custom fields (Service_History__c, Technician__c, Scheduled_Date__c) and technician names become tags for segmentation by assignment. If multiple technicians are assigned, each name is added as a separate tag for crew segmentation. Service_History__c stores a comma‑separated list of recent service types, and scheduled dates use ISO format to support time‑based automations.
Trade Service Pro
Invoice
Mailchimp
Subscriber Custom Field
1:1Invoice totals, payment status, and due dates map to custom merge fields (Invoice_Total__c, Payment_Status__c, Due_Date__c). Payment status (PAID, UNPAID, OVERDUE) also becomes a tag so Mailchimp can filter subscribers by billing standing. If multiple invoices exist for a subscriber, the most recent total is stored in Invoice_Total__c, and the invoice date is recorded in Last_Invoice_Date__c. Historical amounts can be kept in a custom text field (Invoice_History__c) as a semicolon‑separated list.
Trade Service Pro
Equipment / Asset
Mailchimp
Subscriber Tag + Custom Field
1:1Equipment type maps to a tag (HVAC, Plumbing, Electrical, Tree) for segment filtering. Equipment make/model and serial number are stored as custom fields for reference. This preserves field-service context for targeted re-engagement campaigns. If a subscriber has multiple equipment types, each type is added as a separate tag for segmentation. Equipment_Make_Model__c stores make and model; Equipment_Serial__c records the serial number. Tags use Title case (HVAC, Plumbing).
Trade Service Pro
Custom Fields
Mailchimp
Subscriber Custom Merge Fields
1:1Any Trade Service Pro custom fields beyond standard ones get created as Mailchimp custom merge fields before import. Merge field type (text, number, date, dropdown) is set to match the source field type for accurate data display. For picklist fields, options are mirrored in Mailchimp's dropdown configuration. If a source field holds multiple values (comma‑separated), the data is stored as text and can later be split into tags for segmentation.
Trade Service Pro
Email Automations (Scheduling, Dispatch)
Mailchimp
No Equivalent
1:1Trade Service Pro scheduling workflows, dispatch automations, and technician routing rules have no functional equivalent in Mailchimp. These must be rebuilt manually in Mailchimp Customer Journey builder. FlitStack exports workflow definitions as a rebuild reference. During rebuild, your team can use the exported workflow diagrams to map each trigger, condition, and action to a Mailchimp Customer Journey node. This preserves business rules in plain‑language format, reducing the learning curve.
Trade Service Pro
Email Sequences / Templates
Mailchimp
No Equivalent
1:1Trade Service Pro does not primarily store email templates, but any service-related email sequences stored in the platform do not transfer. Mailchimp templates must be recreated. FlitStack can export template content if present. If you have existing HTML templates or plain‑text sequences, FlitStack will extract the content and formatting so your marketing team can re‑import them into Mailchimp's template editor. This reduces re‑creation time and preserves brand voice across transition.
Trade Service Pro
Reports and Dashboards
Mailchimp
No Equivalent
1:1Trade Service Pro reports — jobs completed, revenue by technician, outstanding invoices — have no Mailchimp equivalent. Underlying data migrates, but reporting views must be rebuilt in Mailchimp's campaign analytics. After migration, your team can use Mailchimp's analytics to track open, click, and revenue metrics. For operational metrics like jobs completed or revenue by technician, you will need to query the migrated data via Mailchimp's API or a BI tool.

Migration approach
Pre-migration audit and contact list cleanup
FlitStack audits your Trade Service Pro contact export for duplicate email addresses, formatting issues (missing @ symbols, malformed domains), and unsubscribed or bounced contacts that should import as suppressed rather than active subscribers. This step identifies which contacts should land as subscribed vs. archived in Mailchimp and ensures your import does not trigger Mailchimp's abuse complaint filters on day one.
Field mapping and Mailchimp custom field setup
We map every Trade Service Pro field to either a Mailchimp standard field (FNAME, LNAME, EMAIL, PHONE, ADDRESS, COMPANY), a custom merge field we create pre-import, or a Mailchimp tag. Work-order data, technician assignments, equipment types, and invoice fields get encoded as custom fields. Tags are set up for status values (job stage, payment status, equipment type) so segmentation is available immediately after import.
Import contacts and apply suppression list
The cleaned contact list is imported into your Mailchimp audience using the mapped fields. Simultaneously, unsubscribed and bounced contacts are imported as a Mailchimp suppression list rather than active subscribers. We validate post-import subscriber counts against source record counts and spot-check custom field population before sign-off on the import phase. During import, FlitStack monitors throttling limits and retries failed records to ensure a high completion rate. Any contacts that fail validation (e.g., duplicate email) are logged separately for manual review. After import, a reconciliation report compares record counts and field completeness against the source export to confirm data integrity.
Segment rebuild and automation reference export
FlitStack exports your Trade Service Pro customer segmentation logic (by service type, location, equipment, or job history) as a reference document your team uses to recreate Mailchimp segments. We also export workflow definitions as plain-language rebuild guides for Mailchimp Customer Journey automations. This reference step does not migrate automations — it gives your Mailchimp admin a starting point for the manual rebuild.
Delta-pickup window and go-live verification
After the initial import, a 24-48 hour delta window captures any Trade Service Pro records created or modified during the migration window. FlitStack runs a field-level diff on the delta slice against Mailchimp to verify completeness. An audit log documents every record imported, and one-click rollback is available if the reconciliation check reveals missing data or mapping errors before your team considers the migration complete.
