Chaser

Chaser is a UK-based accounts receivable platform that's been operating since 2014. It offers a comprehensive credit control suite including automated reminders, AI-powered payment predictions, a customer payment portal, and late fee automation. Chaser integrates with Xero and QuickBooks, and also supports CSV import.

Chaser is well-suited to mid-market and enterprise finance teams. Its depth of customisation and multi-entity support make it a strong option for businesses with large receivables books. However, Australian plans start at approximately AUD $399/month, which places it firmly in enterprise territory.

Best for: Larger businesses with dedicated finance teams and budgets to match.

InvoiceSherpa

InvoiceSherpa is a US-based accounts receivable automation tool. It focuses on automated payment reminders, a customer payment portal, and auto-charge functionality for recurring payments. InvoiceSherpa integrates with QuickBooks, Xero, FreshBooks, and Clio.

Its strengths lie in simplicity and the auto-charge feature, which can automatically collect payment via stored card details. Pricing starts at US$49/month. As a US-focused product, it doesn't offer MYOB integration or AUD pricing.

Best for: US-based businesses or those wanting auto-charge payment collection.

PaidNice

PaidNice is focused on payment terms enforcement. Its standout feature is late fee automation — the ability to automatically apply penalties, interest charges, and early payment discounts based on configurable rules. It integrates with Xero, QuickBooks, and Stripe.

PaidNice also offers email and SMS reminders, automated statements, and a customer portal. At US$19/month for the entry plan, it's the most affordable option by sticker price, though all pricing is in US dollars.

Best for: Businesses that want to enforce payment terms with automated late fees and interest charges.

Unpaid

Unpaid is built in Australia, for Australian small businesses. It uses AI to write genuinely personalised reminder emails — not templates with names inserted — and features a 5-stage escalation system that balances firmness with respect. When a customer replies, Unpaid's AI reads the response, detects disputes, payment promises, or questions, and takes appropriate action automatically.

Unpaid integrates with Xero, QuickBooks, and MYOB — the three accounting platforms that dominate the Australian market. It also offers Australia-specific features that no other tool provides: PTRS risk checking against thousands of large businesses, ABN and GST verification, Security of Payment workflow tools for construction, and government client detection.

Best for: Australian small businesses, tradies, freelancers, and bookkeepers who want AI-powered follow-ups and relationship-protecting escalation at an affordable price.
