Overview
Moving from MaxCredible to Twenty CRM is a conceptual shift from an AR automation platform to a general-purpose CRM. MaxCredible organizes data around Debtors, Invoices, Credit Notes, and Reminders tied to a receivables ledger; Twenty CRM uses the standard CRM triad of Companies, Contacts, and Opportunities with a Tasks and Notes engagement timeline. We split MaxCredible's debtor-centric model into these three target objects, preserving invoice relationships as Opportunity-linked line items or custom fields, and mapping credit risk scores and communication logs into the corresponding Twenty fields. The proprietary XML integration format MaxCredible uses for ERP exchanges requires reverse-engineering during discovery; we request sample XML files from the customer's instance to validate the schema before the migration runs. Tone-of-voice templates and workflow automation rules do not migrate as code; we deliver written inventories of both for the customer's admin to reconstruct in Twenty's settings. Tableau report definitions similarly require rebuild against the new data source post-migration.

Object mapping
Each row shows how a MaxCredible object lands in Twenty CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
MaxCredible
Debtor
Twenty CRM
Company or Contact (1:1 split by type)
1:manyMaxCredible Debtors are the primary entity, holding contact details, credit risk scores, payment behavior history, and segment assignments. We map Debtors flagged as business entities to Twenty CRM Company; individuals map to Twenty CRM Contact. The debtor identifier (external_id) is preserved as a custom field for audit trail and cross-reference during the warranty period. Segmentation tags from MaxCredible migrate as multi-select picklist values on the Company or Contact.
MaxCredible
Invoice
Twenty CRM
Opportunity or Custom Object (Invoice)
1:1MaxCredible Invoices are linked to Debtors via foreign relationship and include amount, due date, status, and aging bucket. We map them to Twenty CRM Opportunity if the invoice represents a sales deal in progress, or to a custom Invoice object if the customer requires receivables tracking. The MaxCredible invoice status (open, overdue, paid, disputed) maps to a custom Opportunity stage or Invoice status field. The debtor reference becomes a Company or Contact lookup in Twenty.
MaxCredible
Credit Note
Twenty CRM
Custom Object (Credit Note) or Opportunity adjustment
1:1Credit notes issued against invoices adjust the net receivable balance. We map them to a Twenty CRM custom object with a lookup to the parent Invoice (or Opportunity), the adjustment amount, reason code, and effective date. The net receivable balance is recalculated in Twenty post-migration to reflect all credit note offsets against open invoices.
MaxCredible
Reminder
Twenty CRM
Task
1:1MaxCredible Reminders are time-based tasks triggered by invoice aging rules. We map them to Twenty CRM Task records with the debtor as the related Company or Contact, the invoice as a related custom object or Opportunity, and the due date and priority preserved. The workflow logic driving the reminder trigger is documented but not migrated as automation; the customer's admin rebuilds the aging-based task rules in Twenty's task settings.
MaxCredible
Receivables Ledger
Twenty CRM
Custom Object (Receivables Ledger) or Report
1:1The receivables ledger aggregates all open items per debtor. We extract the ledger as a structured dataset keyed by debtor_id and invoice_id, and reconstruct it in Twenty CRM as either a custom Receivables Ledger object or a report view using Twenty's native charting. Some aggregation fields may require post-migration calculation if the destination schema uses standard opportunity amounts.
MaxCredible
Communication Log
Twenty CRM
Task, Email, or Note (per channel)
1:1MaxCredible tracks outbound communications across email, SMS, and WhatsApp, each with channel-specific metadata. We normalize email logs to Twenty CRM Email (linked to the Company or Contact), SMS logs to Task with a custom channel field set to SMS, and WhatsApp logs to Note with the thread context preserved as body text. The original channel-specific carrier metadata (present on SMS) is stored in custom fields on the Task record. We flag any communications requiring rich thread-context preservation during scoping.
MaxCredible
Tone-of-Voice Template
Twenty CRM
Email Template (documentation for manual rebuild)
lossyMaxCredible's brand voice settings are stored as platform configuration with no structured export mechanism. We extract the template body copy, variable placeholders, and channel assignments as a written document delivered to the customer's marketing or operations team. The customer manually rebuilds these in Twenty CRM's Email Template editor. We do not migrate the tone-of-voice rules as code because they cannot be extracted in a machine-readable format from MaxCredible.
MaxCredible
Risk Score
Twenty CRM
Custom Number Field on Company
1:1MaxCredible's AI-driven credit risk score is a computed snapshot per debtor. We migrate the current score value and the effective date into a custom number field on the Company record in Twenty CRM. The underlying behavioral data (payment timing history, dispute frequency) is not separately exposed for export by MaxCredible, so the destination cannot reproduce the identical AI-generated score without access to the raw behavioral dataset. We document this limitation and recommend recalibrating credit risk models in Twenty post-migration.
MaxCredible
User
Twenty CRM
User
1:1MaxCredible user accounts define access and role assignments. We export user records including name, email, and role. In Twenty CRM these map directly to User records. Any user without a matching email in the destination requires admin provisioning before migration. The MaxCredible role assignments are documented for the admin to map to Twenty CRM workspace roles post-migration.
MaxCredible
Custom Field
Twenty CRM
Custom Field (via Twenty workspace settings)
lossyMaxCredible supports user-defined fields on debtor, invoice, credit note, and reminder objects. We extract the full field schema during scoping and deliver it as a configuration checklist for recreation in Twenty CRM's workspace settings. Custom field values migrate as data after the schema is deployed. Field types are mapped to their nearest Twenty CRM equivalents (text to text, number to number, date to date, picklist to select).
MaxCredible
Document and Attachment
Twenty CRM
Attachment via Twenty file storage
1:1Documents linked to debtors or invoices (contracts, proof of delivery, correspondence PDFs) are extracted as binary files and stored alongside the migrated records in Twenty CRM. File format compatibility (PDF, DOCX, XLSX, images) is preserved. We store the original MaxCredible file URL or reference in a custom field on the attachment record for audit trail during the post-migration warranty period.
MaxCredible
ERP Integration Configuration
Twenty CRM
Written documentation for admin rebuild
lossyMaxCredible connects to ERP systems via XML file uploads over SSL with a proprietary schema for Oracle and SAP. The integration mapping rules, sync frequency, and data transformation logic are MaxCredible-specific and cannot be migrated directly to Twenty CRM's REST API architecture. We document the current integration endpoints, XML schema patterns (validated from sample files during discovery), and the data flow direction so the customer's IT team or an implementation partner can rebuild the integration against Twenty's API.

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.
MaxCredible gotchas
ERP XML integration format is proprietary to MaxCredible
Communication logs use channel-specific formatting
Tone-of-voice templates are not machine-readable for direct migration
Credit risk scores are snapshot values, not raw behavioral data
Twenty CRM gotchas
Import order is enforced and critical
Export limited to 20,000 records and visible columns only
Soft-deleted records count toward uniqueness and trigger restores
API rate limits cap at 200 req/min on Organization tier
No native email sequences — follow-up cadences require external tools
Pair-specific challenges
Migration approach
Discovery and schema mapping design
We audit the source MaxCredible instance across Debtors, Invoices, Credit Notes, Reminders, Communication Logs, Risk Scores, custom fields, and ERP integration configuration. We request sample XML files from the customer's MaxCredible instance to reverse-engineer the ERP integration schema. We pair this with a Twenty CRM workspace assessment to identify which standard objects (Company, Contact, Opportunity, Task) and custom objects the customer needs. The discovery output is a written migration scope with the full object-to-object mapping, custom field schema, and the debtor-to-Company-or-Contact split rule.
Schema deployment in Twenty CRM sandbox
We configure the Twenty CRM workspace with all required custom objects, custom fields, and relationship definitions before any data is loaded. Custom fields are typed to match the source data (text, number, date, select, multi-select). The debtor split rule (business entity to Company, individual to Contact) is validated with a sample of 50 records before full migration begins. Twenty CRM's workspace settings API handles field creation; we deploy to a staging workspace first for validation.
Data extraction and transformation from MaxCredible
We extract debtor records, invoice records, credit notes, reminders, communication logs, risk scores, and document references from MaxCredible using the available export mechanisms. The XML ERP integration samples are analyzed to document the integration pattern for the customer's IT team. All data is transformed into the Twenty CRM import format, with the debtor split applied, foreign keys resolved (invoice to debtor, reminder to debtor and invoice), and communication logs normalized by channel. A reconciliation count is produced before import begins.
Sandbox migration and customer validation
We run a full migration into a staging or sandbox workspace in Twenty CRM using production-like data volume. The customer's finance or operations lead spot-checks 25-50 records against the MaxCredible source — debtor details, invoice amounts, credit note adjustments, and communication log counts — and signs off the mapping before production migration begins. Any field mapping corrections, custom field additions, or debtor split rule adjustments happen in this phase.
Production migration in dependency order
We run the production migration in record-dependency order: custom fields and objects (deployed first to satisfy any lookups), debtors (as Companies or Contacts with the split rule applied), invoices (as Opportunities or custom Invoice objects), credit notes (as adjustments), reminders (as Tasks), risk scores (as custom fields on Company), communication logs (as Tasks, Emails, and Notes by channel), and document attachments. Each phase emits a row-count reconciliation report. We pause HubSpot writes (or the equivalent write-blocking step) during the cutover window to prevent delta records from being missed.
Cutover, validation, and handoff documentation
We run a final delta migration of any records created or modified during the cutover window, then enable Twenty CRM as the system of record. We deliver the tone-of-voice template documentation, workflow automation inventory, ERP integration rebuild guide, and credit risk recalibration recommendation to the customer's admin team. We support a one-week hypercare window for reconciliation issues raised by the finance or collections team. Tableau report definitions require rebuild against the new data source in any BI tool; we do not rebuild them as part of the migration scope.
