How to choose the right invoicing software

The best invoicing software will help you save time and get paid faster. Here are some key features to look out for when choosing an invoicing software:

• Offers customisable invoices: The quality of invoices you send can influence how customers view your business. Choose an invoicing software that lets you customise invoices by adding logos, colours, fonts, layouts and even personalised notes that reflect your brand.
• Automates payment reminders: A good invoicing software should be able to identify and automatically follow up on unpaid invoices. This will not only ensure payment reminders are sent on time but will free up your team to attend to other tasks.
• Improved payment collection: Look out for tools that make it easier to receive payment from your customers. Typically, the best invoicing software is one that supports payment methods your customers often use. This includes credit/debit cards, ACH, auto debits and e-wallets. You should be able to send payment links easily and track different payments received from multiple methods through a general dashboard.
• Provides detailed reports: Insightful reports will help you make better financial decisions for your business. Choose an invoicing software that can provide reports on key things like outstanding invoices, paid and unpaid invoices, revenue reports and tax (VAT) summary. This way, you can easily manage cash flow and your business's tax obligations.
• Integration with other software: An invoicing software that integrates with other tools like payment solutions and accounting software will streamline your entire finance and accounting processes. You will be able to share data across systems easily, and sync payments automatically, so you will always know what's been paid and what's left.

FAQs - best invoicing software

What's the difference between dedicated invoicing software and an all-in-one accounting platform?

Invoicing software helps businesses create, send and manage invoices. All-in-one accounting platforms, on the other hand, provide different services in addition to handling invoicing. They offer tools for managing finances, tracking inventory, forecasting revenue, handling payroll, bookkeeping, submitting taxes and reconciling bank transactions.

Is my financial data secure with online invoicing software?

Yes, credible invoicing software providers make keeping your data secure a top priority. Check for invoicing software that has bank-level encryption, secure cloud storage and GDPR compliance.

What kind of reporting should I look for in invoicing software?

Look out for invoicing software that provides payment status reports (paid, unpaid or overdue invoices), aged receivables report, revenue trends, Tax VAT reports, client/customer reports, and item/service reports to see which products and services generate the most income. This way, you have clear visibility of your business cash flow and can make smarter decisions.

Can invoicing software handle multiple currencies and languages?

Yes, many invoicing software providers provide multicurrency support that lets you issue invoices in your customer's local currency with automatic conversions and up-to-date exchange rates. Invoicing tools also allow you to issue invoices in multiple languages, so your clients have no trouble understanding your invoices.

What level of customer support should I expect?

A good invoicing software should prioritise customer support. Look out for tools that offer 24/7 assistance, free onboarding sessions and access to an agent to walk you through any challenges you may experience

Ultimately, the best invoicing software is one that meets your business's unique needs and makes managing cash flow easier. To decide on the best app for invoicing, consider the features, pricing, integrations and how accessible customer support is. You can also opt for a free trial to get firsthand experience before committing.
