ARCHITECTURE AND ROLLOUT

Where AI Fits into Xero Collections

A practical blueprint for integrating AI agents with Xero's Contacts and Invoices API to automate and prioritize collection workflows.

An effective AI integration for Xero Collections connects at two primary surfaces: the Contacts API for customer segmentation and communication history, and the Invoices API for real-time status on AccountsReceivable, Overdue, and Paid invoices. The AI system acts as an orchestration layer that polls Xero for aging reports, analyzes customer payment patterns and risk (using data like TotalOwed, AverageDaysToPay), and then executes a prioritized, multi-channel outreach strategy. This is not a replacement for Xero's built-in invoice reminders but an intelligent overlay that decides which customer to contact, when, how (email, SMS), and with what message based on learned effectiveness.

Implementation typically involves a serverless function or microservice that uses Xero's webhooks (e.g., InvoiceUpdated, ContactUpdated) to trigger collection logic in near real-time. For example, when an invoice status changes to Overdue, the AI agent can evaluate the contact's history: if they have a good record, it might send a gentle reminder via Xero's email function; if they are a high-risk account, it could escalate to a personalized email drafted by an LLM and log a task in Xero for a human collector. All outbound communication and status changes are written back to Xero as Notes on the contact or invoice, maintaining a complete audit trail within the platform's native interface.

Rollout should be phased, starting with a pilot on a segment of low-risk, overdue invoices to tune the AI's decision logic and message templates. Governance is critical: establish clear rules for escalation thresholds and ensure a human-in-the-loop for any communication that deviates from pre-approved templates. This approach reduces manual dunning work from hours to minutes, improves cash flow by prioritizing high-value delinquencies, and keeps all collection activity centralized within Xero's system of record.

AUTOMATED COLLECTIONS FOR XERO

Key Xero API Surfaces for AI Integration

The Core Data Layer for Collections

The Contacts API and Invoices API form the foundation for any AI-driven collections system. The Contacts API provides access to customer details, payment terms, and credit limits, which are essential for segmenting accounts by risk profile. The Invoices API allows you to retrieve the complete AR aging report in real-time, including invoice status (AUTHORISED, PAID, VOIDED), amounts, due dates, and payment history.

An AI agent uses these endpoints to build a dynamic, prioritized collections list. It can query for all invoices where Status is AUTHORISED and DueDate is in the past, then enrich each with the customer's AccountsReceivable balance and PaymentTerms from the Contacts API. This creates the single source of truth for deciding which accounts to engage, how urgently, and through which channel.

AUTOMATED WORKFLOWS

High-Value AI Collections Use Cases for Xero

Integrate AI agents directly with Xero's Contacts and Invoices API to transform manual, reactive collections into a proactive, data-driven process. These patterns prioritize effort, automate communications, and maintain a complete audit trail within the platform.

01

Intelligent Aging Report Prioritization

An AI agent analyzes the Xero Aged Receivables Detail report daily, scoring each overdue invoice based on customer payment history, invoice amount, and days overdue. It automatically updates the Contact record in Xero with a 'Collection Priority' custom field, ensuring collectors focus on the highest-risk accounts first.

02

Personalized Dunning Sequence Automation

AI drafts and sends personalized collection emails or SMS via Xero's integrated communication tools. It sequences reminders based on the customer's priority score, escalating from friendly reminders to payment ultimatums. All sent messages are logged as Notes on the Contact and Invoice records in Xero for a complete history.

Follow-up timing
03

Promise-to-Pay Tracking & Rescheduling

When a customer replies to a collection message with a payment promise, an AI agent uses natural language processing to extract the date and amount. It creates a Task in Xero for the collector to follow up on that date and can automatically reschedule the next reminder in the sequence if the promise is broken, keeping the workflow dynamic.

04

Dispute & Deduction Triage

AI reviews customer replies for keywords indicating a dispute (e.g., 'wrong product', 'not received'). It automatically tags the Invoice in Xero with a 'Dispute' status, routes it to a dedicated queue for the collections or sales team, and can even draft a response requesting supporting documentation, preventing wasted effort on uncontested amounts.

05

Cash Application Forecasting

By analyzing the status of all active collection workflows (promises, disputes, silences), the AI generates a short-term cash forecast. This data can be written to a Tracking Category or custom report in Xero, giving finance leaders visibility into expected cash inflows from collections over the next 7-30 days.

Collector Copilot Dashboard

An AI-powered internal dashboard surfaces a daily action list for collectors, pulling data from Xero's API. It shows each high-priority contact, suggested communication templates, recent interaction history, and key risk factors. This turns Xero from a system of record into an active collections command center, reducing context-switching.

XERO INTEGRATION PATTERNS

Example AI-Powered Collections Workflows

These workflows illustrate how AI agents can be integrated with Xero's Contacts, Invoices, and Bank Transactions APIs to automate and prioritize collections. Each pattern is designed to reduce manual follow-up, improve cash flow, and maintain accurate audit trails within the platform.

This workflow uses AI to analyze the AR aging report and segment customers for targeted follow-up.

  1. Trigger: A scheduled daily job queries Xero's Invoices API for all AUTHORISED invoices where Status is OVERDUE.
  2. Context Pulled: For each overdue invoice, the agent pulls:
    • Customer contact details and AccountNumber from the Contacts API.
    • Full payment history and average days to pay.
    • Invoice amount, due date, and any existing SentToContact status.
  3. AI Action: A scoring model evaluates each customer/invoice pair based on:
    • Amount overdue and delinquency duration.
    • Historical payment reliability.
    • Total outstanding balance.
    • Any recent communications logged in Xero. Customers are segmented into priority tiers (e.g., High, Medium, Low).
  4. System Update: The priority score and segment are written back to Xero as a custom field on the Contact or as a note against the invoice for collector visibility.
  5. Next Step: High-priority accounts are automatically queued for the Personalized Reminder Generation workflow. Medium and Low tiers are scheduled for batch email sequences.
ARCHITECTING AI-DRIVEN COLLECTIONS

Implementation Architecture & Data Flow

A production-ready integration design that connects AI agents to Xero's core APIs to automate dunning workflows, prioritize outreach, and maintain a complete audit trail.

The integration architecture is built on Xero's Contacts API and Invoices API, with webhooks for real-time event triggers. The core data flow begins when an invoice's due date passes, triggering a webhook to an AI orchestration service. This service pulls the invoice details and the full contact history for the customer, including payment patterns and communication logs. An AI agent then evaluates the AR aging report data, the customer's risk segment, and the invoice amount to determine the optimal collection action—such as sending a reminder email, scheduling a call, or escalating to a human collector. The agent drafts a personalized message using Xero's contact details and logs the proposed action back to the contact notes or a custom field via the API, ensuring all activity is recorded within the platform's audit trail.

For implementation, the AI system typically runs as a cloud service that authenticates via OAuth 2.0 to the Xero tenant. Key objects involved are the Contact (for customer profile and history), Invoice (for status, due date, amount), and Payment (for tracking partial payments). The agent's decision logic can be configured with rules (e.g., "first reminder after 7 days") and enhanced with ML models trained on historical collection outcomes. Actions are executed through Xero's Email endpoints or integrated third-party communication channels like Twilio for SMS. A reconciliation job runs nightly to sync statuses, ensuring the AI's view of "collections priority" matches the live AR ledger in Xero.

Rollout should follow a phased approach, starting with a pilot on a subset of low-risk, overdue invoices to tune the agent's tone and timing. Governance is critical: all AI-generated communications should be reviewed by a collector for the first 30 days, and a human-in-the-loop approval step should remain for any escalation action (e.g., payment plans, write-offs). The integration includes a dashboard for finance managers to monitor the AI's hit rate (reminders that led to payment), override its recommendations, and audit the complete interaction log stored in Xero. This design reduces manual follow-up from hours to minutes per week while keeping the finance team in control of customer relationships and compliance.

XERO COLLECTIONS AUTOMATION

Code & Payload Examples

Fetching Overdue Invoices and Contact Details

To prioritize collections, your AI agent first needs to retrieve overdue invoices and enriched customer data from Xero. This involves querying the Invoices API with a status filter and joining it with Contact data to get communication preferences and payment history.

Key API Endpoints:

  • GET /api.xro/2.0/Invoices with Statuses=AUTHORISED and Where=DueDate < {date}
  • GET /api.xro/2.0/Contacts/{ContactID} for contact details and custom fields like PreferredContactMethod.

The payload returned provides the invoice line items, amounts, and the contact's email/phone, which the AI uses to personalize outreach. This data retrieval is typically scheduled to run daily via a background job, populating a queue for the AI agent to process.

ENTERPRISE-GRADE AI INTEGRATION

Governance, Security, and Phased Rollout

A secure, controlled implementation of AI for collections that respects Xero's data model and your business policies.

A production-grade AI integration for Xero collections operates through a secure middleware layer, not directly inside Xero. This layer uses Xero's OAuth 2.0 API with scoped permissions (typically accounting.transactions, accounting.contacts.read, accounting.contacts.write) to fetch invoice and contact data. All AI processing—such as risk scoring customers, drafting email reminders, and scheduling follow-ups—occurs in this governed environment. Communication logs (e.g., 'AI drafted reminder for Invoice INV-001') are written back to Xero as notes on the contact or invoice, creating a complete, auditable trail within the platform's native audit log.

Rollout follows a phased, risk-managed approach: Phase 1 (Monitor & Learn): The AI system runs in a read-only 'shadow mode' for 30 days, analyzing your AR aging report and customer payment history to build risk profiles and suggest collection actions without taking any. Phase 2 (Assisted Workflow): AI-generated tasks (prioritized collection list, draft emails) are pushed to a human-in-the-loop queue in your team's existing task manager (e.g., Asana, Slack). Collectors review, edit, and manually send communications, with all outcomes fed back to train the AI. Phase 3 (Conditional Automation): For low-risk, low-value invoices (e.g., under $500, 30 days overdue), the system can be configured to automatically send pre-approved reminder sequences, escalating to a human only if a payment promise is broken or a dispute is logged in Xero.

Governance is enforced through configurable business rules: you define which customer segments, invoice age brackets, and dollar amounts are eligible for automated actions. All AI-generated content is tagged and versioned, allowing for prompt tuning and compliance review. Before any automated email is sent, it can be routed through an approval step or a secondary LLM for policy compliance checking. This architecture ensures the AI acts as a force-multiplier for your collections team while maintaining strict control, aligning with financial controls and data privacy requirements inherent to accounting platforms.
