What is Milestone Billing? Why Your Firm May Need a Phased Billing Model

Milestone billing, also known as phased billing, is great for firms with mid to long-term projects looking to avoid scope creep.

Milestone billing, also known as phased billing, is a popular billing model in the A/E and professional services industries due to the industries’ project-driven revenues. To determine if this phased billing model is right for your firm, consider the length of your projects. If you often conduct mid to long-term projects and would like to avoid scope creep, a phased billing model can be a beneficial option for you. Phased billing is excellent at defining objectives, deadlines, and deliverables.  

What is Milestone Billing? 

Milestone billing allows you to bill in phases, hence the description “phased billing”. Using the phased billing model, you can bill for project work by each milestone that you define with your client. When a milestone is reached, your client is billed for the designated partial amount of the total amount of the project. Milestones can be billed for services that involve multiple work orders and resources delivered over time.  

Each milestone is essentially a sub-goal that helps to achieve the main project goal. When you use the phased billing model, instead of invoicing every couple of weeks, you can set up a phased billing agreement where your client pays for each milestone/deadline as it’s reached.  

The amount due at each milestone and each deadline can defer from project to project, this model is project-specific and will be unique to each new case.  

Phased Billing vs Project-based Billing 

You’re probably most familiar with project-based billing. Project-based billing offers upfront pricing with all your project costs already negotiated and resolved before the project even begins. This type of billing is great for short-term projects; however, it can be unsuitable for longer projects. This is where milestone billing comes in. 

Milestone billing allows you to space out invoices to make larger projects more manageable. This is especially beneficial for the client and a good way to get them to agree to a larger, more expensive project that they may not want to pay for all of it up front. It’s also helpful for your firm to maintain a steady cash flow over a longer length of time and set goals for your team to work toward.  

A phased billing model can help structure budgets and make sure everyone stays within those budgets if the project takes longer than anticipated. It’s also a beneficial way to visualize a relationship between payment and progress.  

When Not to Use Phased Billing 

A phased billing model isn’t for everyone. If your project doesn’t have concrete deliverables, milestone billing might not be the best option. Administrative work is a good example of where a phase billing model wouldn’t work. Administrative tasks are typically ongoing, without any milestones, so hourly compensation or a salary would make more sense in this case.  

If you’re working on a smaller project, you can still use milestone billing, but if there are not a lot of deliverables, this type of billing could just cause confusion. Instead, for shorter projects, paying directly at the start makes more sense.   

Phased Billing and Time Tracking 

When you’re using a phased billing model, it’s important to make sure you’re tracking time alongside it. Every milestone will have its own unique amount of time and effort involved. If there is ever a discrepancy when it comes to the estimated vs actual time spent on a milestone, your time tracking can resolve this quickly.
