How to invoice for variation orders and extras on a job

Introduction to Variation Orders

A variation order (VO) represents any change to the agreed scope of work, materials, or specification within a project. Whether initiated by the client or an unforeseen necessity, understanding how to correctly invoice these variations ensures you are protected financially and legally. In the dynamic world of construction and trades, changes are inevitable. A well-documented VO can be the difference between a smooth project and one fraught with disputes.

Why Variation Orders Are Important

When clients request changes mid-job, having a VO in place protects against unexpected costs and workload. Without this formal agreement, you risk complications with payment and project completion. In many cases, clients may not fully understand the impact their requested changes have on the timeline and budget. A clearly defined VO helps manage these expectations and facilitates transparent communication.

Handling a Variation Before Starting Extra Work

Before commencing additional work, it’s essential to have everything documented. Obtain a written agreement detailing costs and time implications. This might be through a revised contract or an addendum. A well-structured VO not only safeguards your interests but also establishes professionalism and clarity in your dealings with clients.

Steps to Take

• Get changes in writing: Draft a detailed document outlining every modification, ensuring that both parties are on the same page.
• Confirm costs and timelines: Discuss and document any additional costs and how the changes will affect the project's timeline.
• Seek client signatures on all documents: A signed VO is legally binding. It confirms that the client has agreed to the terms and conditions set forth.

Elements of a Variation Invoice

When invoicing for a VO, include the original contract reference, VO number, a detailed description of changes, the agreed price, and any impact on the completion date. Transparency in your invoicing not only helps in getting paid promptly but also builds trust with your clients.

Invoicing Variations

When preparing invoices, you can either list changes as separate line items or issue a separate invoice depending on your preference and the project's complexity. Some contractors prefer a detailed breakdown, which can help clients understand exactly what they are being charged for. This transparency can reduce the likelihood of disputes over payment.

What Happens If You Do Extra Work Without a Signed VO?

Without a signed VO, you face the risk of not getting paid. A lack of agreement makes it difficult to enforce payment for the additional work. In the UK, an estimated 20% of all construction disputes arise from changes not agreed upon in writing. To avoid becoming part of this statistic, always secure a signed VO before starting any extra work.

Verbal Agreements: Why They're Risky

Verbal agreements can lead to misunderstandings. Document these interactions with follow-up emails or messaging apps like WhatsApp to maintain a reliable record. In the event of a dispute, these records can serve as evidence of the agreed terms, although they may not hold as much weight as a signed document.

Dealing with Late Variations

Clients might introduce changes late in the project. It's important to issue a VO promptly and require client approval before undertaking any extra work. Late changes can disrupt schedules and increase costs significantly. By addressing these variations quickly and efficiently, you reduce the potential for conflict and ensure the project stays on track.

Preventing Disputes

Maintain a job diary with photos and signed VO logs. These records become invaluable if disputes arise. Ensure that everything is dated and compiled in an orderly fashion. This documentation can provide a clear timeline of events, making it easier to resolve disagreements. Additionally, fostering open communication with clients throughout the project can help prevent misunderstandings from escalating into disputes.

Understanding the Financial Impact of Variations

Variations can significantly impact the financial outcome of a project. In the UK, construction projects often experience cost overruns due to unanticipated changes. According to a study by the Chartered Institute of Building, variations can increase project costs by up to 15%. By implementing a structured approach to managing variations, you can mitigate these financial risks and maintain your profit margins.

Costing Variations Accurately

Accurate costing of variations is essential to avoid disputes and financial losses. Use your experience and knowledge of the project to estimate the additional time, labour, and materials required. Consider potential delays and their impact on the overall project timeline. By providing clients with a comprehensive breakdown of the costs, you set clear expectations and reduce the likelihood of conflict.

Negotiating Variations with Clients

Negotiating variations with clients can be challenging, especially if they are unfamiliar with construction processes. Clear communication is key. Explain the reasons for the variation and its implications on the project. Provide detailed documentation to support your claims. By presenting a professional and transparent case, you increase the likelihood of reaching an agreement that benefits both parties.

Using Technology to Manage Variations

Modern technology offers tools that can streamline the process of managing variations. Project management software allows you to track changes, update timelines, and communicate with clients efficiently. These tools can also generate reports that provide a snapshot of the project's current status, making it easier to address variations promptly. By embracing technology, you enhance your ability to manage projects effectively and minimise the risk of disputes.
