Xero’s Late Fee Limitations
Despite being a powerful accounting platform, Xero lacks native late fee capabilities. Here’s what Xero currently offers and where it falls short:
What Xero Provides
Xero allows you to manually add late fee line items to existing invoices and set up payment reminder sequences. You can create standard late fee items in your inventory and apply them to overdue accounts. The platform also provides aging reports to identify overdue invoices.
Critical Limitations
No Automatic Calculation: Xero cannot automatically calculate late fees based on predefined rules or overdue periods. Every fee must be manually added.
No Triggered Application: There’s no way to set up rules that automatically apply late fees when invoices reach certain overdue thresholds.
Limited Customization: You cannot create tiered late fee structures or customer-specific late fee rules within Xero’s native functionality.
No Integration with Payment Reminders: Late fees cannot be automatically included in payment reminder emails or linked to your reminder sequences.

The Invoice Settings panel in Xero shows payment terms and reminder options but no automated late fee configuration.

Adding late fees requires manually creating new line items for each overdue invoice, or creating a completely new invoice - a time-consuming process for businesses with multiple overdue accounts.
Solutions: Manual vs Automated Approaches
Manual Workarounds in Xero
Weekly Review Process: Set up a weekly routine to review aging reports, identify overdue invoices, and manually add late fee items. This requires creating standard late fee products in your item library and consistently applying them.
Spreadsheet Tracking: Many businesses export overdue invoices to spreadsheets, calculate fees externally, then import them back into Xero. While functional, this approach is error-prone and time-intensive.
Payment Reminder Customization: Modify your payment reminder templates to mention late fee policies, though fees still require manual application.
Partial Automation Solutions
Third-Party Apps: Some Xero marketplace apps offer limited late fee functionality, but most focus on payment reminders rather than automatic fee calculation and application.
Custom Integrations: Businesses with development resources sometimes build custom API integrations, but these require ongoing maintenance and technical expertise.
The Problem with Manual Late Fees
Manual late fee management creates significant challenges for businesses using Xero. Finance teams spend hours each week identifying overdue invoices, calculating appropriate fees, and creating additional charges. This process is not only labour-intensive but also inconsistent: some overdue accounts may be overlooked while others receive fees at different intervals.
The financial impact is substantial. Businesses typically lose 10-15% of potential late fee revenue due to manual oversight, while the administrative burden costs an average of 3-5 hours per week for companies processing 50+ invoices monthly. More critically, inconsistent late fee application can damage client relationships and create cash flow unpredictability.
Fully Automated Solution: Fairly Good
Fairly Good provides comprehensive late fee automation that integrates seamlessly with Xero, offering features that native Xero functionality doesn’t have:
- Automatic Fee Calculation: Set percentage-based or flat-rate fees that calculate automatically based on invoice amounts and overdue periods
- Flexible Rule Configuration: Create customer-specific late fee rules, grace periods, and fee structures
- Seamless Integration: Automatic invoice syncing with Xero ensures everything is up-to-date
How Fairly Good Automates Late Fees
Fairly Good transforms Xero’s late fee management through intelligent automation that works behind the scenes. The system monitors your invoices continuously, applying predefined rules to calculate and add late fees automatically.
Key Features
Smart Rule Engine: Configure percentage-based fees (e.g., 1.5% monthly), flat rates ($25 per occurrence), or interest-based (10% annually) with customizable grace periods.
Customer Segmentation: Set different late fee rules for different customer categories - enterprise clients might have longer grace periods while smaller accounts have immediate fee application.
Transparent Tracking: All late fees can be created as new invoices, or appear as standard Xero line items with detailed descriptions, depending on your requirements.
Integration Benefits
The system works entirely within Xero’s framework, meaning your existing workflows, reporting, and reconciliation processes remain unchanged. Late fees appear on customer statements, integrate with payment reminders, and flow through to financial reports automatically.
Setup Walkthrough
Setting up automated late fees with Fairly Good takes less than 10 minutes. Here’s the complete process:
Step 1: Initial Configuration
Define customer segmentation by adding contacts to different contact groups. You can define as many contact groups as you need eg. one for “Late payers”, one for “Special Customers” etc. Automation rules are then defined for a contact group and will only be executed against invoices for that contact group.

After connecting your Xero account, access the Late Fee Configuration panel. Here you’ll define your default late fee structure and basic rules.
Step 2: Fee Structure Setup
Configure your fee structure by selecting percentage-based rates (recommended for larger invoices) or flat fees (suitable for consistent penalty amounts). Most businesses use 1.5% monthly or $25 flat fees.
Step 3: Grace Period Configuration

Set grace periods for different customer types. Standard accounts might have 7-day grace periods while preferred customers receive 14-day extensions before late fees apply.
Step 4: Rule Activation

Activate your late fee rules and review the monitoring dashboard. The system immediately begins scanning for eligible invoices and will apply fees according to your configured schedule.
Step 5: Customer Communication Setup

Configure automatic email notifications to inform customers when late fees are applied. Templates can be customized to match your brand voice and include payment instructions.
Step 6: Monitoring and Reporting

Use the comprehensive reporting dashboard to track late fee application, monitor revenue impact, and analyze customer payment behavior trends.
Case Study: Expected Impact
Background: Mid-Size Consulting Firm
A 50-employee consulting firm processes approximately 200 invoices monthly with an average value of $2,500. Before automation, they manually applied late fees to roughly 15% of overdue accounts, missing significant revenue opportunities.
Implementation Results
Revenue Recovery: Automated late fees increased late fee collection from $3,750 to $8,200 monthly-a 118% improvement in fee revenue.
Time Savings: Administrative time spent on late fee management decreased from 6 hours weekly to 30 minutes for monitoring and exception handling.
Payment Behavior: Average payment time improved from 42 days to 35 days as customers responded to consistent late fee application.
Cash Flow Impact: Improved late fee collection and faster payments generated an additional $54,000 annually in cash flow improvements.
Key Success Factors
The firm’s success stemmed from implementing tiered late fee structures (1% at 15 days, 1.5% at 30 days) and maintaining clear customer communication about fee policies. Automated application ensured no overdue accounts were overlooked.
Frequently Asked Questions
How does automated late fee calculation work?
Fairly Good monitors your Xero invoices continuously, checking payment status against your configured rules. When an invoice reaches the specified overdue threshold, the system automatically calculates the appropriate fee based on your settings and adds it as a line item to the original invoice.
