Best all-round invoicing inside accounting software: Xero
Xero includes professional invoices, mobile invoicing, payment-status tracking and automated reminders as part of its wider accounting platform. It is a strong option when you want every invoice to feed directly into bookkeeping, VAT and reporting.
Best for automated follow-up and payments: QuickBooks
QuickBooks lets businesses create branded invoices, track paid and overdue balances, set recurring invoices and use automated reminders. It also integrates invoice payments with the wider accounts, reducing the need to re-enter sales data.
Best for freelancers: FreeAgent
FreeAgent combines invoicing with project tracking, time tracking, expenses and UK tax features. That makes it especially useful for consultants, contractors and freelancers who want to turn billable work into invoices without managing a separate invoicing system.
Best low-cost or free option: Zoho Books
Zoho Books includes invoices, quotes, recurring invoices, payment reminders, online payments and a customer portal. Its free plan can be a strong starting point for a micro business, while paid plans add more automation and users.
Best for client-service businesses: FreshBooks
FreshBooks is built heavily around invoicing, proposals, client payments and project work. Its UK plans also support MTD-compliant VAT returns, making it worth considering for service businesses that care more about billing and client workflows than advanced accounting complexity.
