Migrate from MaxCredible to Mailchimp

MaxCredible Debtor records map 1:1 to Mailchimp Audience Members. The debtor name, email address, phone number, and any custom fields migrate as standard Mailchimp merge fields (FNAME, LNAME, EMAIL, PHONE) plus any user-defined merge field tags. We flag records missing an email address as a reconciliation issue because Mailchimp requires a valid email for audience membership. The debtor ID from MaxCredible is preserved in a merge field for cross-reference.

MaxCredible's email communication history (sent reminders, collection notices, payment confirmations) is channel-specific data that has no direct Mailchimp equivalent. Mailchimp tracks campaign sends and opens, not inbound collection communications. We extract the email log content, date, and channel type and write them as tagged notes on each audience member record. The original communication content becomes a tagged string per contact that the marketing team can reference for personalization context, but the timeline does not appear as a native activity feed in Mailchimp.

MaxCredible's branded tone-of-voice templates are stored as platform-specific configuration that is not machine-readable for direct migration. We export the template body copy and variable placeholders as a structured reference document that the customer's marketing team uses to manually rebuild the templates in Mailchimp's template editor. We do not migrate the template as code. The reference document includes the template name, channel (email/SMS/WhatsApp), variable placeholders, and the copy body so the team can reconstruct intent without reverse-engineering from scratch.

MaxCredible's AI-generated credit risk score per debtor is a computed snapshot value with no behavioral data underlying it available for export. We migrate the current score value and its effective date as a Mailchimp merge field (CREDIT_RISK_SCORE) and optionally tag the contact based on risk tier (High/Medium/Low) for segmentation. The score cannot be reproduced in Mailchimp because the underlying behavioral dataset is not exposed. We recommend recalibrating any risk-based segmentation logic in Mailchimp using engagement and purchase data post-migration.

MaxCredible Invoice records have no equivalent object in Mailchimp. Mailchimp is an email marketing platform and does not have a data model for invoices, line items, payment status, or receivables. We extract the invoice list as a reference CSV and recommend a dedicated accounting platform (QuickBooks, Xero, Zoho Books, or the customer's existing ERP) as the destination for invoice data. The debtor-to-invoice relationship is preserved in the reference CSV so that if the customer later connects a CRM or accounting tool, the relationship can be re-established.

Credit notes are adjustments against invoices in MaxCredible's receivables ledger. Mailchimp has no credit note or accounting object. We export credit notes as a structured CSV linked to the parent debtor and invoice reference, which the customer's accounting team can import into their accounting platform post-migration. We flag this limitation explicitly in the migration scope so that the finance team is aware a separate accounting migration is needed.

MaxCredible Reminders are time-based tasks triggered by invoice aging rules. Mailchimp's automation model is based on customer journey triggers (signup, purchase, date-based) rather than invoice-aging logic. Reminder definitions and their debtor/invoice references are documented as a written inventory so the customer's operations team can rebuild equivalent automations in Mailchimp's Customer Journey builder using engagement data as the trigger instead of invoice age.

The receivables ledger aggregates open items per debtor and is a financial summary that requires a destination accounting system to receive it meaningfully. We export the ledger as a structured dataset for the customer's finance team to load into their accounting platform. Mailchimp does not support this data type and we do not attempt to store financial summary data in contact merge fields as a workaround because it would misrepresent the data model.

MaxCredible user accounts (name, email, role) map to Mailchimp account users. The migration extracts the user list and maps role names to Mailchimp permission levels (Admin, Manager, Author, Viewer). Only users who need access to Mailchimp are included; any MaxCredible-only users (such as finance-only roles that do not apply to email marketing) are noted in the scope for the customer's admin to provision selectively.
