To simplify your decision, here’s a quick comparison of the top invoicing tools for consultants, covering key features, pricing, customization, and ease of use:
Invoicing software for small business owners and consultants should do more than just send bills. It should save time, cut down on admin tasks, and make it easier to get paid faster.
Here are the essential features to look for:
Tofu checks all the boxes in terms of these must-have features. It works with limited internet connectivity, is ideal for mobile users, and integrates with Stripe for payments. You also get the ability to customize your invoices for branding and create estimates or invoices through saved client information!
The best invoicing tool choice comes down to what your consulting business really needs, not just features, but how the software fits into your day-to-day work.
Here’s how to narrow it down:
Do you bill per project, per job, or send one-off invoices? Choose a tool that matches how you work, with features like quick estimate-to-invoice conversion and professional templates.
If you’re managing multiple clients, look for platforms that keep client details, past jobs, and invoice history in one place for simple follow-ups.
Most consultants work on the go, whether it’s from job sites, client offices, or coffee shops. A good invoicing software should let you create, send, and manage invoices from your phone or tablet without losing functionality.
Time spent figuring out software is time not spent on client work. Look for tools with clean interfaces, valuable support, and features that are easy to access, even if you’re not tech-savvy.
If you’re new to billing software or switching from spreadsheets, ease of use matters more than advanced features.
Some platforms offer comprehensive accounting, inventory, or team collaboration features, but if you’re a solo consultant or freelancer, you might not need such advanced features. Choose a plan that fits your current stage and budget.
This is especially important for those exploring invoicing software for freelancers; simple, effective tools are often the better fit.
Generic invoicing software might get the job done, but tools built specifically for consultants can save time, reduce errors, and speed up your payments. Here’s how:
Consultants’ invoicing software doesn’t just handle billing; it lets you work smarter, present professionally, and spend less time chasing payments.
Consulting work often comes with complex billing, different rates, project scopes, and client expectations. Manual invoicing or generic tools can lead to mistakes, delays, or missed payments. Here are some of the biggest challenges consultants face, and how the right software solves them.
The Challenge: Switching between projects can lead to misassigned tasks or invoicing delays. Inefficient invoice delivery or incomplete client information accounts for 61% of late payments.
How Software Helps: Tools tailored for consultants centralize clients, projects, and billing, keeping everything organized and client-ready.
The Challenge: Mis-entered client details or billing amounts cause delays, from both the client and admin sides. 39% of invoices contain errors, many due to manual data entry or unclear formats.
How Software Helps: Pre-built templates and pre-filled client info mean fewer mistakes and invoices that arrive accurate and polished.
The Challenge: Manually logging hours across different clients and tasks often leads to underbilling or mistakes.
How Software Helps: Consultant-ready platforms include built-in timers and project-based time logs, making sure your invoices reflect actual work, in real time.
The Challenge: Administrative billing tasks, like entering data, matching expenses, and formatting, eat into your work hours. Manual invoice processing takes an average of 14.6 days, slowing down your cash flow.
How Software Helps: Automation shortcuts, like converting time logs into invoices or snapping receipts into expenses, free up hours every week.

To invoice for consulting services, start by creating a clear, professional invoice that outlines the work completed, the hourly or project rate, and the total amount due.

Consultants usually bill clients by sending detailed invoices that outline the services provided and agreed-upon rates. Many use specialized invoicing software to create professional invoices, manage client details, and track payments in one place. This simplifies the billing process and helps ensure you get paid on time.
Most consultants set payment terms between 15 and 30 days from the invoice date. Clear payment terms, like “Net 30”, let clients know when to pay the invoice. Some consultants also offer early payment discounts or require deposits up front to keep cash flow steady.
