How to extend a contract

It can take a considerable amount of time and resources to create a new contract once the previous one has expired.

You’re often starting from scratch, even though it will be almost a carbon copy of the contract that went before.

So, why not extend it instead?

In this article, we will show you the most effective ways to extend your contracts, ensuring they remain valid and legal.

We’ll cover what a contract extension is, how to carry it out, and how PandaDoc can help you.

Key takeaways:

Contract extensions are a simple way to increase the length of a contract without having to draw up a whole new agreement.
They serve as addendums to an existing contract rather than an alteration of the original document.
Efficiently extending a contract requires examining the existing document and evaluating its performance.
Contract management software helps streamline the entire process.

What is a contract extension?

A contract extension is an agreement to continue an existing contract beyond the original end date. It allows work or services to proceed under the same or slightly modified terms without creating a new contract. This approach is efficient and commonly used when both parties are satisfied with the original arrangement or require additional time to fulfill their obligations.

A contract extension can also be a good opportunity to review and change some of the contract’s terms.

Generally, the creator of the original contract will produce an extension agreement (or contract extension addendum) to be signed by all the parties involved.

This will have all the details of the extension, including the proposed new length of the contract.

Alternatively, if there are possible changes to discuss, a contract extension letter may be sent to the other party, who will then send an acceptance letter when they’re happy with the changes.

A contract extension agreement isn’t the same as a contract renewal, which involves creating a new contract and may be more suitable for individuals or companies that want to completely renegotiate the terms.

For example, a retailer may take on seasonal employees on a temporary basis.

If they’re happy with a particular employee’s work, they may decide to extend their contract.

In this case, minimal changes would be needed, so the retailer could simply send their employee a contract extension letter explaining how long they wished to extend their employment for.

Let’s dive a little deeper into how extensions and renewals differ.

What’s the difference between a contract extension and a contract renewal?

A contract extension continues the original agreement, usually with the same terms. A contract renewal, creates a new agreement that may also include updated pricing, terms, or conditions.

These are two distinct approaches to how a business can continue a relationship. Understanding the differences can help you choose the right option for your needs.

Contract extension

As introduced above, a contract extension essentially maintains the existing agreement but lengthens its duration. This means that the terms, pricing, and obligations stay the same, but the date changes. These are typically handled through an addendum or amendment instead of a new contract.

You would likely choose an extension if:

The existing terms still work for both parties
The project timeline has shifted or needs more time
You want to avoid renegotiating the entire agreement

Contract renewal

A contract renewal means you’re creating an entirely new contract once the current one expires. Renewals might include some of the elements of the old contract, but they typically have updated terms, pricing, and/or scope of work.

Consider the renewal process when:

The business relationship or service needs have changed
You want to renegotiate pricing, deliverables, or legal protections
The contract has expired or is about to expire

Pros and cons of extending vs. renewing a contract

Approach	Pros	Cons
Contract extension	– Fast and simple to execute – Maintains continuity with existing terms – Minimal legal review needed	– May keep outdated terms in place – Limited flexibility for changes – Not suitable for long-term adjustments
Contract renewal	– Opportunity to update terms and pricing – Reflects current business conditions – Can reset the relationship on better terms	– Requires more negotiation and legal review – May take longer to finalize – Could disrupt continuity if not timed well

How to choose the right option

If you’re happy with your current agreement and simply need more time, you may want to consider a contract extension for efficiency. But if your business goals, pricing, or legal requirements need an update, going with a renewal will allow you to renegotiate and start fresh.

Just be sure to document whichever option you choose so that there’s legal transparency and mutual understanding between all parties involved.

The importance of properly extending a contract

It’s essential to remember that a contract is a legally binding document, so you must be careful when making additions.

If you’re not confident in creating documents that use legal terms, you should look at our standard business document templates to give you an idea of what kind of language to include.

A contract extension is an addendum, i.e., a document to be added to your original contract. What you’re not doing is altering the original.

All changes must comply with the essence of this, or you’re at risk of voiding the whole thing. A null and void contract is the same as having no contract.

Note: You can’t extend a contract after its expiration as, legally, it doesn’t exist anymore. However, you can create a new contract using the existing terms. There’s also the option of backdating a new contract, so there’s no gap between the two.

How to extend a contract efficiently: A step-by-step process

On the surface, contract extensions are pretty simple; you want your contract to be extended, so you create an addendum to the original document that allows you to do just that.

It’s a little like overtime in a basketball game.

So, in essence, it’s straightforward, but you still need to follow the correct procedures when carrying out the process.

Contract extensions must be implemented properly and be compliant with your local jurisdiction.

Let’s look at how to implement one efficiently, one step at a time.

1. Examine the present contract

Before creating your extension agreement, review the original contract and identify any changes you wish to make.

Are the terms and conditions up to date? Is there anything in the contract that’s now irrelevant, or is there anything missing from it?

When you extend a contract, you may use it as an opportunity to update the terms and/or make additions to the agreement that may be beneficial to the parties involved.

You may even want to remove a clause or condition that you no longer consider necessary.

Also, look at the duration of the original contract.

Do you want to extend it by the same amount of time? You may be happy to extend it for longer now that you’ve built up trust with the other party.

2. Contact the other party

All parties to the contract must be contacted to agree to a contract extension. Not only do they need to know that they’ve been given the option to extend the term of the contract, but they should have the chance to discuss any changes. Remember, an addendum to a contract needs to be signed by all parties.

3. Evaluate contract performance

Before deciding whether to extend a contract, consider how the original contract has performed.

This will give you an idea of any updates or additions that should be included in the contract extension agreement.

To evaluate contract performance, look at:

ROI

Contracts should be beneficial to all parties. You both give something to receive something back, whether it be payment, goods, or your time.

Contracts that are worth the return on investment should be extended, but if one or both parties aren’t happy, it may be best to let the contract expire.

You could always consider a contract renewal in the future, but it may be better to create a whole new contract instead.

Punctuality

Time is of the essence for many contracts. Look at whether the terms of your contract were met by the date agreed upon. If they weren’t, why was this the case?

It’s possible that unrealistic deadlines may need to be adjusted moving forward (or that one of the parties is unreliable and not worth contracting with again).

Consistency

It’s also important to look at the consistency as well as the quality of the work done under the contract.

Both parties may be happy with the results of the contract now, but to extend your relationship, you need trust.

One way to build trust is by having seen that the other party has been consistent in following the terms and conditions of your contract.

This also shows they’re organized and care about the original contract and fulfilling it satisfactorily.

4. Choose the terms of the extension

The main role of an extension is to extend the end date of a contract, but you can also use it to remove irrelevant parts, update terms and conditions, and make additions.

Be sure to add any new terms with care, as they should not contradict the overarching purpose and idea of the original.

Doing so could render the contract null and void.

As mentioned earlier, reading through the original contract will help you choose the terms of your extension.

5. Create the extended contract

Once you’ve chosen the terms of your extension, you’ll need to create a contract extension agreement or an addendum to the contract.

This will be a separate document from the original.

When looking at how to write an addendum to a contract, these are the essential elements you need to include:

The original contract, including start and end dates.
The duration of the new contract, including the end date.
Names and details of signatories, including their signatures.
Proposed changes, including additions and deletions of the original terms of the contract.

6. Seek professional assistance when necessary

It’s a good idea to get a professional to look over any legal documents you’ve created before anyone signs them.

This could be your company’s legal team or a lawyer who works in contract law.

This will ensure your agreement complies with the laws and regulations of your jurisdiction.

They should also be able to check that the agreement doesn’t go against the original contract.

7. Put the extension into action

Depending on the nature of your contract, putting your extension into action can vary in terms of how it looks.

If the parties involved are within your company, you can create an extension agreement to be signed in person.

If you’re dealing with clients or other businesses, however, you may need to create a contract extension letter to send out.

The other party can then reply with an acceptance letter if they’re happy with the new terms.

Many companies choose to use emails and eSignatures to save time and resources.

Each party should have a copy of the extension agreement. It’s also important to send a copy to any relevant departments in your business, including HR.

Examples of contract extensions across industries

Contract extensions are relevant in almost any industry where agreements have fixed terms.

Here are some common ones:

Employment contracts

A company could hire a marketing consultant on a six-month contract that expires at the end of December. If the project is going well, but the team needs more time before the next campaign’s launch in the new year, they could extend the current contract. That would keep the rate the same and maintain the current responsibilities, which would avoid having to draft a new contract.

Vendor or service agreements

Say you’re a construction firm that has a one-year maintenance contract with an equipment supplier. Your project experiences delays, which means you’ll need the equipment longer than originally planned. You can sign an extension addendum to continue the maintenance services for an additional six months, maintaining the same pricing and terms.

SaaS or software licenses

If your company’s annual SaaS subscription for your CRM platform is set to expire soon, but you’re in the middle of integrating new features, an extension would be a good option. This would allow you to keep access to your subscription without renegotiating terms or pricing for a period of time while you review long-term options.

All three of these examples show how contract extensions can help keep business running with existing terms that fit your needs, so you can avoid disruptions and delays.

FAQ

What is a good reason for extension of a contract?

Extending a contract is a good idea if both parties are happy with the current terms but need more time to complete the work. This could look like project delays, ongoing negotiations for a renewal contract, or a need for a temporary solution if maintaining services is necessary.

How do I extend the term of an agreement?

A short written addendum or amendment that both parties sign is the simplest way to handle an extension. This document details the new end date and confirms that everything else in the original contract still stands, like terms and pricing.

To avoid any gaps in coverage, it’s a good idea to finalize an extension before the current contract expires.

Is e-Signature valid for contract extension?

Yes! An electronic signature, or eSignature, is legally valid for contract extensions in most jurisdictions. It just needs to meet local eSignature laws such as the ESIGN Act (in the U.S.) or eIDAS (in the EU). A secure eSignature software like PandaDoc can help you make sure the extension is up to code and easy to track.

How do contract extensions impact existing terms?

Contract extensions are intended to lengthen the duration of an existing agreement while keeping all the existing terms, conditions, and obligations the same. But if there are small changes needed for your business needs, like new deliverables or adjustments, those can be clearly documented in the extension addendum so that there’s no confusion later on.
