Corinthian vs Xero Invoicing: Detailed Comparison for 2026
Xero is a cloud accounting platform used by millions of small businesses, particularly in the UK, Australia, and New Zealand. It handles everything from bank reconciliation to payroll to inventory, and invoicing is one module within that suite. For businesses that need accounting and invoicing in one system, Xero delivers.
Corinthian is a focused invoicing and collections platform. It doesn't do bank reconciliation, payroll, or inventory management. What it does is handle the full lifecycle of an invoice -- from creation through delivery, collaboration, tracking, and payment recovery -- with more depth than Xero's invoicing module provides.
Accounting suite vs. invoicing platform
This is the fundamental distinction. Xero gives you a complete accounting system where invoicing is one capability among many. Corinthian gives you a specialized invoicing system that integrates with accounting tools like Xero.
If you need double-entry bookkeeping and bank feeds alongside invoicing, Xero covers both. If your day-to-day work revolves around creating, sending, and collecting on invoices, and you find yourself switching between Xero, email, and Slack to manage that process, Corinthian consolidates the invoicing workflow.
Pricing
| | Corinthian | Xero | |---|---|---| | Starting price | Pro plan | $15/mo (Starter) | | Mid-tier | Team plan | $42/mo (Standard) | | Upper tier | Business plan | $78/mo (Premium) | | Invoice limits | Unlimited on all plans | 20 invoices/mo on Starter | | User pricing | Included in plan | Included, varies by region | | Bank reconciliation | No (use Xero for this) | Yes | | Dunning workflows | Included | Not available | | Payroll | No | Available in some regions |
Xero's Starter plan limits you to 20 invoices per month. For businesses that send more than that, you need Standard or Premium. Corinthian doesn't cap invoice volume on any plan.
Ease of use
Xero's interface is designed for accounting professionals and business owners who handle their own books. The invoicing section is straightforward, but it sits within a larger application with bank feeds, chart of accounts, fixed assets, and reporting modules. If you only use invoicing, the surrounding complexity adds noise.
Corinthian's interface is built around an inbox model. Invoices, client communications, and team discussions appear in a single workspace. There's no chart of accounts or bank reconciliation screen because those features don't exist in the product. The result is a faster workflow for people whose job is sending and collecting on invoices.
Both products have mobile apps. Xero's covers accounting and invoicing. Corinthian's focuses on invoice management and communication.
Invoice features
Xero handles standard invoicing well. You can create invoices with line items, apply taxes, set payment terms, and add your branding. Templates are functional but offer limited customization -- you can change colors and add a logo, but layout control is minimal.
Corinthian goes deeper on invoice customization. The template editor supports brand colors, typography, layout choices, and rich text descriptions on line items. Multiple templates let you use different designs for different client types. Batch invoicing generates invoices in bulk from client lists.
| Feature | Corinthian | Xero | |---|---|---| | Custom templates | Full editor with branding | Basic color and logo | | Multiple templates | Yes | Limited | | Rich text descriptions | Yes | No | | Batch invoicing | Yes | No | | Recurring invoices | Yes | Yes | | Multi-currency | Yes, with auto conversion | Yes | | Partial payments | Yes | Yes | | Credit notes | Yes | Yes | | Invoice approval workflow | Yes | Yes (on higher plans) | | Quote to invoice conversion | Yes | Yes |
Team collaboration
Xero supports multiple users with role-based permissions. Team members can access different sections of the accounting system based on their role. For invoicing, this means different people can create, approve, and send invoices. Xero's History and Notes feature logs changes to invoices, but real-time collaboration on a specific invoice isn't part of the product.
Corinthian treats collaboration as a core feature. Each invoice has a threaded conversation where team members can discuss the account. When a client replies to an invoice email, the reply appears in the same thread alongside internal notes and team discussions. Approval workflows route invoices through configurable review steps before sending. RBAC controls are granular -- you can define exactly which actions each role can perform.
| Feature | Corinthian | Xero | |---|---|---| | Team workspaces | Yes | Yes | | Role-based access | Granular RBAC | Standard roles | | Invoice-level threads | Yes | No | | Approval workflows | Configurable multi-step | Basic approval (higher plans) | | Internal notes | Threaded per invoice | History log | | Client reply integration | Yes | No | | Audit logs | Yes | Higher plans | | SSO/SAML | Yes | Premium only |
Automation and dunning
Xero sends invoice reminders. You can set up automatic reminders at intervals after the due date. The reminders use email and a standard template. For most businesses, this handles the basic "your invoice is overdue" notification.
Corinthian's dunning engine is built for teams that need structured collection processes. Multi-step workflows define what happens at each stage of a delinquent account: reminder emails, firmer follow-ups, phone call tasks, escalation to a manager, or formal collections notices. Each step has its own template, timing, and channel. The system tracks whether the client opened the email, clicked a link, or viewed the invoice through the portal.
Quiet hours prevent messages from going out at inappropriate times. CAN-SPAM compliance is automatic. You can create different dunning workflows for different client segments or invoice amounts.
| Feature | Corinthian | Xero | |---|---|---| | Payment reminders | Multi-step, multi-channel | Email, scheduled | | Dunning workflows | Escalation engine | Not available | | Email tracking | Opens, bounces, clicks | Not available | | Portal view tracking | Yes | Not available | | Quiet hours | Built in | Not available | | CAN-SPAM compliance | Automatic | Not available | | Segment-based workflows | Yes | Not available | | Custom escalation rules | Yes | Not available |
API and developer tools
Xero has a mature API designed primarily for accounting integrations. It covers contacts, invoices, bank transactions, reports, and more. OAuth 2.0 authentication is required. The API is well-documented and has a large developer ecosystem, with many third-party apps built on it.
Corinthian's public REST API is designed around documented invoicing resources such as clients, invoices, payments, products, recurring records, and sequences. Official SDK packages and customer-managed webhook subscriptions are not published in the public docs yet, so integrations should use direct HTTPS requests today.
| Feature | Corinthian | Xero | |---|---|---| | REST API | Public invoicing resources | Comprehensive (accounting-focused) | | SDKs | Not published as an official suite | Multiple languages | | Webhooks | Connected-service webhooks; customer-managed subscriptions not public | Invoice and payment | | Authentication | API keys | OAuth 2.0 | | Developer ecosystem | Growing | Large and established |
Xero's API ecosystem is broader because it covers the full accounting stack. Corinthian's API is deeper for invoicing-specific operations.
Integrations
Xero integrates with over 1,000 apps across payments, banking, CRM, inventory, e-commerce, and HR. The Xero App Marketplace is one of the largest in small business software.
Corinthian connects to Stripe today and supports exports or REST API handoffs for accounting workflows. Native Xero and QuickBooks sync, PayPal, GoCardless, and broader communication connectors are coming soon.
Reporting
Xero provides comprehensive financial reporting: profit and loss, balance sheet, aged receivables, bank reconciliation reports, budget vs. actuals, and more. These reports serve accountants and business owners who need a full financial picture.
Corinthian reports on invoice operations: collection rates, average days to payment, dunning workflow conversion rates, delivery success rates, team performance metrics, and aging breakdowns. These metrics serve AR teams and finance operations managers who need to optimize the collection process.
| Report type | Corinthian | Xero | |---|---|---| | Aged receivables | Yes | Yes | | Collection rate tracking | Yes | No | | Dunning conversion rates | Yes | No | | Delivery success rates | Yes | No | | Team performance | Yes | No | | Profit and loss | No | Yes | | Balance sheet | No | Yes | | Bank reconciliation | No | Yes | | Tax reports | No | Yes |

Who should choose Xero
Choose Xero if you need a full accounting system and invoicing is one part of your financial operations. Xero is a strong choice for businesses that need bank reconciliation, tax reporting, and payroll alongside invoicing. If your accountant uses Xero or you need compliance features for UK/AU/NZ tax regimes, the ecosystem support is hard to match. Xero works best when your invoicing volume is moderate and you don't need complex collection workflows or team collaboration on individual invoices.
Who should choose Corinthian
Choose Corinthian if your primary workflow is invoicing and collecting payments, not accounting. If you have an AR team that spends time chasing overdue invoices, coordinating internally about client accounts, and needs visibility into whether clients are opening their invoices, Corinthian addresses those specific problems. You can pair Corinthian with Xero -- use Corinthian for the invoicing workflow and Xero for the accounting. This gives you depth in both areas without compromise.
