Discover Features of Leading Invoice Applications

Invoicing software has come a long way from basic templates and spreadsheets. Today’s leading invoice applications are sophisticated, mobile-friendly platforms that do far more than generate PDFs. They help you track payments, manage clients, handle VAT, stay MTD-compliant, and run a tighter, more profitable business.

But with so many options on the market, how do you distinguish a genuinely useful tool from one that looks impressive in a demo but frustrates you in daily use? This guide walks through the features that separate the best invoice applications from the rest.

Core Invoicing Features

Professional Invoice Creation

The foundation of any invoice app is the ability to create clear, professional invoices quickly. Look for:

Customisable templates with your logo and brand colours
Automatic invoice numbering
The ability to add multiple line items with descriptions, quantities, and unit prices
VAT calculation (standard rate, reduced rate, zero-rated, and exempt)
Payment terms and due date setting
Notes and terms and conditions fields

Client Management

A good invoice app maintains a client database so you never have to retype an address. Features to look for:

Save client name, address, email, and contact details
View invoice history per client
Track outstanding balances per client
Sub-client or multiple contact support for larger organisations

Item and Service Catalogue

For tradespeople and service businesses, being able to save standard job descriptions and prices saves significant time. The ability to add saved items to an invoice in seconds — rather than typing descriptions repeatedly — reduces both time and errors.

Payment and Cash Flow Features

Payment Tracking

Knowing which invoices are paid, unpaid, or overdue is essential for cash flow management. Leading apps provide:

Status tracking (draft, sent, viewed, paid, overdue)
Automatic overdue flagging
Payment recording (partial and full payments)
Outstanding balance summaries

Payment Reminders

Automated payment reminders sent to clients at configurable intervals reduce the time you spend chasing. The best apps let you customise the tone and timing of these reminders.

Multiple Payment Methods

Modern clients pay by bank transfer, card, or payment link. Look for apps that support adding payment details and, where available, direct payment integration.

Expense and Record-Keeping Features

Expense Tracking

The best invoice applications double as expense trackers. Features include:

Manual expense entry with categories
Receipt photograph capture and OCR extraction
Mileage tracking
Expense summaries by category and period

This is particularly important under Making Tax Digital, where all income and expenses must be maintained digitally.

Bank Reconciliation

Some apps connect directly to your business bank account to automatically import and categorise transactions. This significantly reduces manual data entry.

Reporting and Insights

Financial Reports

Leading apps generate reports including:

Profit and loss summaries
VAT reports
Outstanding invoices and aged debt
Income by client or project
Expense breakdowns by category

Tax Estimates

Particularly useful for sole traders and self-employed individuals, real-time tax estimates based on your income and expenses help you set money aside throughout the year rather than facing a surprise in January.

MTD and Compliance Features

As MTD for ITSA extends to more taxpayers, MTD-compatible software is increasingly important. Check that the app:

Is recognised by HMRC for MTD submissions
Supports quarterly update submissions for ITSA
Handles MTD for VAT if you are VAT-registered
Maintains the digital audit trail HMRC requires

Mobile and Usability Features

For tradespeople and business owners who are rarely at a desk, mobile capability is not optional — it is essential.

Native iOS and Android apps (not just a mobile website)
Offline functionality for when you are in areas with poor signal
Camera-based receipt capture
Quick invoice creation in under a minute
Intuitive interface that does not require training
