Overview
Powered Now is field-service management software built for UK trade businesses — plumbers, electricians, gas engineers, builders. It stores clients, contacts, quotes, invoices, jobs, diary entries, certificates, forms, and supplier expenses. Mailchimp is an email marketing platform organized around audiences, contacts, tags, merge fields, and Customer Journeys. There is no direct data-model parity between these platforms: Powered Now's operational records (jobs, invoices, diary entries, certificates) have no native Mailchimp equivalent. FlitStack AI migrates what can map — client contact records, company data, phone numbers, addresses, custom fields — into Mailchimp audiences and merge fields. We tag contacts by job status or invoice state where Mailchimp's tagging model supports it. We surface the gap explicitly so your team decides whether to rebuild operational context in Mailchimp via custom merge fields or accept reference-only preservation. The migration runs via Powered Now's API export and Mailchimp's bulk contact import API. For records that cannot map directly, such as historical job chains or certificate documents, FlitStack AI generates separate reference exports so no data is lost in the transition.
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 Powered Now 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.
Powered Now
Client
Mailchimp
Contact
1:1Powered Now Client records map to Mailchimp contacts within a designated audience. Email address is the unique identifier — clients without an email address are flagged for manual review before import. The client's primary contact name splits into First Name and Last Name merge fields.
Powered Now
Company
Mailchimp
Contact
1:1Powered Now stores company name on the Client record. In Mailchimp this maps to the COMPANY merge field. If multiple clients share the same company name in Powered Now, they remain as separate Mailchimp contacts tagged by that company — Mailchimp does not support company as a separate lookup object.
Powered Now
Job
Mailchimp
Contact (Tag + Merge Field)
1:1Jobs have no Mailchimp equivalent — a Job is an operational record tied to a Client. FlitStack AI converts the most recent Job status and type into Mailchimp Tags (e.g., 'Boiler Install', 'Maintenance Complete') and stores the Job ID in a custom merge field for reference. Historical job data is exported as a separate CSV for admin review.
Powered Now
Quote
Mailchimp
Contact (Tag)
1:1Quote status (Draft, Sent, Accepted, Declined) becomes a Mailchimp Tag on the associated Client contact (e.g., 'Quote Sent', 'Quote Accepted'). The quote value and line items cannot map to standard Mailchimp fields — these are preserved in the Quote reference CSV export.
Powered Now
Invoice
Mailchimp
Contact (Tag + Merge Field)
1:1Invoice status (Paid, Sent, Overdue, Draft) maps to Mailchimp Tags (e.g., 'Invoice Paid', 'Invoice Overdue'). Invoice amount and number are stored in custom merge fields (INVOICE_AMOUNT, INVOICE_NUMBER) so the contact record carries a financial reference without requiring a separate accounting export.
Powered Now
Certificate
Mailchimp
Contact (Reference CSV)
1:1Certificates (gas safety, electrical, building) have no Mailchimp equivalent — Mailchimp does not support document attachments or compliance-record objects. We export the Certificate data (type, issue date, expiry date, linked Job ID) as a separate CSV for compliance records management. Contacts are tagged by certificate type if that information is actionable for segmentation.
Powered Now
Contact / Phone
Mailchimp
Contact
1:1Powered Now contact phone numbers map to the PHONE merge field in Mailchimp. Mobile and landline numbers are not distinguished in Powered Now's default setup; both write to the same PHONE field. If separate mobile fields exist in Powered Now, they map to PHONE and a custom MOBILE merge field respectively.
Powered Now
Diary Entry
Mailchimp
Contact (Tag)
1:1Diary entries are scheduling records tied to Jobs and Clients — they do not map to any Mailchimp construct. We export diary entries as a separate CSV keyed by Client ID so the scheduling history is preserved even though it cannot become part of Mailchimp's contact model.
Powered Now
Supplier Invoice
Mailchimp
Contact (Reference CSV)
1:1Supplier invoices and purchase orders are payable records owned by the business, not the client — Mailchimp has no accounts-payable concept. These export as a separate CSV keyed by Supplier name. If a Supplier is also a Contact in Powered Now, their Mailchimp contact record can be tagged with 'Supplier' for reference.
Powered Now
Custom Fields (Client / Job / Invoice)
Mailchimp
Merge Field
1:1Powered Now custom properties (e.g., 'Boiler Type', 'Landlord Name', 'Payment Terms') are created as Mailchimp Merge Fields in the destination audience. Merge field names are sanitized (uppercase, underscores) and types inferred from source data type. Mailchimp's 255-character limit is enforced — long-text custom fields truncate with a flag in the migration report.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Powered Now gotchas
No public REST API means migration requires reverse-engineered data access
Certificate expiry dates require manual re-validation post-migration
Making Tax Digital data is tied to the Powered Now MTD-compliant invoice format
Attachment blobs export as raw files without a relational manifest
Mailchimp gotchas
Contact count includes unsubscribed and non-subscribed records
Automation workflows cannot be exported
Account suspensions trigger silently during migration
Template HTML is Mailchimp-specific and may not render in other platforms

Migration approach
Scope the Powered Now data and configure the Mailchimp audience
FlitStack AI connects to Powered Now via API using your account credentials and inventories all Clients, Contacts, Jobs, Quotes, Invoices, and Certificates. We identify custom fields, multi-company associations, and records missing email addresses. In parallel, we create the Mailchimp audience and pre-create all merge fields (FNAME, LNAME, PHONE, COMPANY, ADDRESS*, and custom fields for job IDs, invoice amounts, certificate expiry dates). Merge field types are inferred from source data types — dates, numbers, and text each get appropriate Mailchimp field types.
Run de-duplication and email validation on client records
We scan all Powered Now client records for duplicate email addresses, malformed email syntax, and missing email addresses. Duplicate-email records are merged: all tags from every associated record are combined onto one Mailchimp contact. Records with invalid or missing emails are flagged in the pre-migration report — your team decides whether to add a placeholder email (e.g., [email protected]) or exclude those records from the initial import and handle them manually.
Map and transform fields; apply tagging logic for job and invoice status
Every field in the Powered Now data model is mapped to a Mailchimp contact field or tag per the field mapping plan. Job status and invoice status become tags (e.g., 'Job Complete', 'Invoice Paid'). Job types become tags for segmentation (e.g., 'Gas Safety', 'Boiler Install'). Certificate types and expiry dates become merge fields or tags depending on whether the data is actionable for email campaigns. Mailchimp's 255-character merge field limit is enforced — long fields are flagged for truncation or external storage. The transformation logic is logged in the field-level mapping report your team reviews before migration.
Execute a sample migration with field-level diff and tag verification
A representative slice of records — typically 100 to 500 clients spanning multiple job types, invoice states, and custom field configurations — is imported into the Mailchimp audience first. FlitStack AI generates a field-level diff: source values versus Mailchimp values for every mapped field, plus a list of all tags applied per contact. Your team verifies that job status tags are correct, invoice amounts landed in merge fields, and custom fields did not truncate unexpectedly. No full migration commits until the sample passes your acceptance criteria.
Run full migration with delta-pickup and operational data export
The full contact import runs via Mailchimp's bulk import API. A delta-pickup window of 24 to 48 hours after the full import captures any new or modified client records created in Powered Now during cutover. All operational data that cannot map to Mailchimp — Jobs, Certificates, Diary Entries, Supplier Invoices — is exported as separate CSVs keyed by contact ID so the complete record set is preserved even though it does not live inside Mailchimp. FlitStack AI generates an audit log of every import operation and one-click rollback is available if reconciliation fails.
