Updated: Oct 31

Construction contracts are the lifeblood of your project. As a contractor, one of the biggest decisions you'll face is deciding on the type of contract to use.

Understanding Lump Sum Contracts

Before diving in, let's clarify what we mean by Lump Sum Contracts. These contracts, which are often called "fixed price contracts," call for the provider to provide certain services at a set price. Many clients and workers like this type of contract because it is easy to understand and reliable.

Advantages of Lump Sum Contracts

When considering a lump sum contract, the most immediate benefit is the fixed price. With this type of contract, the client and the contractor agree on a fixed total price. This gives both sides some financial certainty.


Predictability and Financial Planning

With a lump sum contract, the contractor knows the exact amount they'll receive upon project completion. This certainty aids financial planning in construction. You can budget with more confidence, knowing your income is guaranteed as long as you fulfill your end of the contract.


Simplicity and Transparency

Lump sum contracts are also straightforward, offering simplicity and transparency. Since the costs of a job are known from the start, there's no need for complicated accounting. The simple nature of these contracts can save contractors a lot of time and make it less likely that they will have a disagreement.

Drawbacks of Lump Sum Contracts

While there are undeniable advantages to using a lump sum contract, they also come with potential risks. Making an informed selection requires having a thorough understanding of these hazards.


Estimation Risks

The key drawback to a lump sum contract is the risk associated with cost estimation. If your cost estimates are inaccurate, you could end up undercharging for your services, eroding your profit margin.


Scope Changes

Changes in scope during the project are another risk. While change orders can adjust the project price, frequent changes can cause delays and inflate costs. This can turn a once profitable project into a financial liability.
