Back: What is Invoicing?

What are the Best Invoicing Software Features?

  • Automated Invoicing

An automated invoicing system can make invoicing easy and minimize potential errors that can occur in manual invoicing systems. Recurring invoices can be scheduled to be sent out on-time with all the correct information including client name, address, job number, and balance owing. Automated invoicing also automatically calculates the sales tax and matches payments with invoices, so everything will be up to date and easy to access.

  • Progress Invoicing

Sometimes big projects can require multiple invoices or a deposit from your client. This can lead to multiple invoices, disorganization, and reluctance from clients who are not willing to pay everything upfront. With progress invoicing, you can start a job and invoice as you hit milestones in your work. This creates consistent cash flow, team motivation, and offers low-risk options for your customers.

  • Custom Templates

Add a personal touch to your invoices with custom templates. Choose from pre-uploaded invoices and customize the colours, fonts, and imagery. Add a professional touch by uploading your logo to your customized template! You can also set your customer’s language preferences and even send invoices in international currencies by assigning different currencies to specific accounts.

  • Invoice Payments

Getting paid has never been easier! Add a Pay Now button directly in your invoices to let your customers pay by credit card in just a few clicks. By providing everything in one place, it'll be easier for your clients to pay you on-time and correctly. Make things convenient for your customers, by setting up recurring payments. Your customers’ billing information will be securely stored, and you’ll have a consistent cash flow throughout the project.

  • Estimates Tool

You and your clients will be at ease with an estimating tool built into your invoicing system. This tool allows you to create estimates and quotes that can be converted into an invoice with a simple click of a button. It even allows you to include discounts and payment terms directly in the invoice.

  • Real-Time Alerts

Built-in notifications will ensure you get paid on-time and correctly every time. Receive read receipts when your client opens their invoice, and alerts when invoices are paid and past due. You can also pass along the notifications to your clients and send out reminders to let them know a payment is due.
