Here are the 6 best construction billing methods that you can use in your business.

Progress Billing

One of the most common methods of construction billing is to use milestones (or progress) to bill a project. Essentially, you bill the client based on hitting certain goals during a construction project. This billing will happen in regular intervals or cycles as long as progress is made. The contractor sends an invoice to the client when every phase is finished asking for payment for the services done up to that point. The invoice includes a thorough cost breakdown, the percentage of completion, and any appropriate retainage.


  • Cash flow management: Progress billing allows contractors to receive partial payments throughout the project, helping with cash flow and funding ongoing expenses.
  • Transparency: The invoicing process provides clients with a clear understanding of the project’s progress and costs incurred.


  • Increased administrative effort: Progress billing necessitates precise cost and completion % tracking, which can take a lot of time and calls for rigorous record keeping.
  • Potential payment delays: Clients may refuse to pay if they disagree with the cost estimates or the proportion of the job completed, which could cause payments to be received later than expected.

Advanced Billing

This type of construction billing takes place before the project starts. It requires a tremendous amount of trust from the client and an incredible record from the construction company. Most of the time, clients will pay in lump sums although some may make payments before a project starts. While not as common as some on this list, advanced billing does have a whole host of benefits:


  • Funds are ready: Contractors can budget and plan with a secure budget. This can help them save money and cut costs.
  • Move quickly: Because payment has been made, funding for a project will not hold them back.


  • Project runs over budget: Construction projects often run over time and over budget, meaning it could cost you money to complete the job.
  • Stakeholders could be screwed: Stakeholders are at the mercy construction company which could lead them to put more than normal pressure on the construction company.

Cost-Plus Billing

Cost-plus billing, sometimes referred to as cost-reimbursable billing, includes charging clients for the actual expenses incurred throughout the project as well as a predetermined charge or profit margin. This means that companies will need to track details like:

  • Labor
  • Materials
  • Tools
  • Subcontractor expenses
  • Overhead
  • And more

Some clients like this method more, because they are seeing exactly where their money is going. Is it right for you though? Here are some things to consider:


  • Transparency: Clients can see the actual costs incurred, encouraging transparency and trust in the billing process. Construction companies can provide more insights into labor and materials.
  • Flexibility: Cost-plus billing allows for adjustments to the project scope or unforeseen expenses without compromising profitability


  • Uncertain final cost: Costs may fluctuate if a project goes over budget or over time. This can be bad for the client and construction company.

Potential disputes: Disputes or negotiations may result from disagreements about whether the incurred costs or markup are reasonable.

Fixed Price Billing

In a fixed-price contract, the total cost of the entire construction project is predetermined. Upon completion or at particular project milestones, the contractor provides a single invoice for the agreed-upon sum. This approach is frequently utilized for smaller projects or when the work’s scope is clearly specified. Most of the time payments are made in lump sums or over the course of 1-2 payments.


  • Predictable costs: Clients get a clear grasp of the complete cost of the project from the start, which benefits budgeting and financial planning.
  • Reduced administrative effort: Because there is no need for frequent cost tracking or calculations, fixed-price billing simplifies the invoicing process.


  • Limited flexibility: Changes to the project scope or unforeseen expenses may necessitate negotiation and possibly contract or pricing revisions.

Risk of underestimation: There is a risk of underestimating costs and potential profit loss if the project's scope or needs are not clearly established upfront.

Time and Material Billing

Time and materials (T&M) billing is a billing method where clients are charged for the actual time spent and materials used in the construction project. This is a lot like cost plus billing, however, pricing is based on a daily or hourly rate of labor along with materials. Most companies use this method for projects with no set end date or undefined path. It is one of the most helpful construction billing methods.


  • Keep going: Even if the project has no set end goal or clear stopping point, your company can still get paid for that time.
  • Flexibility for changes: Allows the project to change without your company having to bear all the costs. Instead, the client will.


  • Uncertain total project cost: Clients may experience uncertainty until the project is completed because the ultimate project cost is dependent on the actual time and materials used.
  • Potential disputes: Clients may question the justification of work hours or material costs, perhaps leading to disagreements or difficulties in reaching an agreement on final numbers.

Arrears Billing

Arrears billing is waiting until the end of a project to bill for services. This means that all pricing is calculated at the end of the project. This is comparable to the fixed-cost billing method however it happens at the end of the project. This does provide both some benefits and challenges to the process.


  • Delayed payment: Clients can delay payments until the end of the project. This can give them more time to secure funding and have a more accurate goal for the project.
  • Negotiation power: Arrears billing can allow for more negotiation power from construction companies.


  • You upfront the cost: A construction company with have to take the risk of bearing the cost. That could spell disaster if something goes wrong with the company and there is not enough cash on hand.
  • Financial stress: Because a company is waiting to be paid, it can put stress on the company. While arrears billing is common, it still incentivizes companies to finish jobs as fast as possible.

Consistency in invoicing helps maintain cash flow and keeps clients informed about project costs.

What should I do if a client disputes a charge on the invoice?

If a client raises a dispute regarding a charge, it's important to address it promptly and professionally. Review the invoice and supporting documentation to identify any errors or misunderstandings. Engage in open communication with the client to clarify the issue and find a resolution that satisfies both parties.
