Deadlines are a normal part of running a business - delivering work to a client, finishing a construction job, meeting a regulatory due date, or hitting a milestone under a supply contract.
But sometimes, even with the best planning, delays happen. A supplier misses a shipment. A client changes scope mid-project. Weather or access issues slow down work on site. A key team member is unexpectedly off sick.
In many of these situations, the legal question becomes: can you get an extension of time (often called an “EOT”) without breaching your contract or exposing your business to claims for delay damages?
This guide breaks down what an extension of time is, when it matters, how to request one (and how to respond to one), and how to build better extension of time protection into your contracts from day one.
What Is An Extension Of Time (And Why Does It Matter For Small Businesses)?
An extension of time is an agreed change to a deadline. It usually comes up where a contract sets a completion date, delivery date, or milestone date - and something happens that makes meeting that deadline unrealistic or impossible.
For small businesses, deadlines often connect to real costs and risks, such as:
- Payment milestones (you only get paid when certain dates or stages are met)
- Penalties (like liquidated damages for late completion)
- Service credits or fee reductions
- Termination rights (the other party can end the contract if you’re late)
- Reputation risk (late delivery can harm repeat work and referrals)
In plain terms: an extension of time can be the difference between a manageable delay and a dispute that becomes expensive fast.
Extension Of Time Vs “Just Being Late”
It’s tempting to assume that being late is fine if the other party “seems okay with it”. But legally, you’re safer when the timeline change is documented.
Without a documented extension of time, you could be in breach of contract - even if the delay is understandable. That breach might trigger:
- a claim for losses caused by the delay
- withholding of payment
- termination for default
- a loss of trust that affects future negotiations
If the contract needs updating, documenting the change properly through a Deed of Variation can reduce ambiguity and protect your position.
When Do You Usually Need An Extension Of Time?
An extension of time can apply to almost any commercial arrangement, but it commonly arises in contracts where “time matters” and deadlines are linked to money, performance, or risk.
Common Scenarios For Small Businesses
- Client services: a customer changes the scope, gives feedback late, or doesn’t provide inputs you need (like content, approvals, access, or data).
- Construction and trade work: site access delays, weather events, variations, or third-party dependencies (e.g. inspectors, certifiers, suppliers). (Note: in construction, extension of time processes can be more technical and may be affected by the specific contract and any applicable security of payment regime.)
- Supply and manufacturing: raw material shortages, freight delays, port issues, or supplier bottlenecks.
- Software and tech projects: integration blockers, changes in requirements, delays in stakeholder sign-off, or security review hold-ups.
- Leases and fit-outs: delays in landlord approvals, building works, or council processes.
What Usually Causes Disputes About Extensions Of Time?
Extension of time disputes tend to happen when:
- the contract doesn’t clearly say how an extension of time is requested or granted
- the business requesting the extension of time can’t clearly show what caused the delay
- notice requirements weren’t followed (for example, you needed to notify within 2 business days, but you notified 2 weeks later)
- there’s disagreement about whether the delay is within someone’s control
- the customer thinks the supplier is using an EOT to cover poor project management
This is why the paperwork matters just as much as the practical reality of the delay.
How To Request An Extension Of Time (Step-By-Step)
If you need an extension of time, the goal is to stay calm, be organised, and communicate in a way that matches your contract. Even if the relationship is friendly, it’s still worth treating this as a formal process.
1. Check The Contract First (Don’t Guess)
Before you send any email, look for clauses covering:
- timeframes and milestones
- variations (scope changes often justify time changes)
- delay events (sometimes called “excusable delay” or “force majeure”, depending on the contract)
- notice requirements (how quickly you must notify, and how)
- consequences of delay (penalties, termination, withholding payment)
If you’re not confident about what the contract requires, it can be worth getting a contract review so you don’t accidentally waive rights or admit liability in writing.
2. Identify The Cause Of The Delay (And Whether It’s Your Risk)
Not all delays are treated equally. Many contracts distinguish between:
- client-caused delay (e.g. late approvals, late information)
- third-party delay (e.g. supplier issues)
- force majeure / external events (e.g. natural disasters, depending on how “force majeure” is defined in your contract)
- your internal delay (e.g. staffing shortages, scheduling issues)
This matters because a contract may only allow an extension of time for certain types of delay (and may require you to take specific steps to qualify for it).
3. Notify Early (Even If You Don’t Have All The Details Yet)
Many small business disputes escalate because someone waited too long to raise the issue.
If your contract has a strict timeframe to notify (for example, within 2-5 business days of becoming aware of the delay), send a quick “initial notice” first. You can always follow up with more detail.
4. Put The Request In Writing (And Be Specific)
In most cases, a good extension of time request should include:
- what deadline is affected (e.g. Milestone 2 delivery date)
- what caused the delay (facts only, no blame language if possible)
- when the delay started and whether it is ongoing
- the impact on the timeline (how many days/weeks)
- your proposed revised date
- your mitigation steps (what you’re doing to reduce the delay)
If the extension of time is linked to a scope change, you may also need to document the scope and price change as a contract update via a contract amendment.
5. Document The Agreed Outcome Properly
If the other party agrees to an extension of time, avoid leaving it as a vague “sure, no worries” email if the contract is high value or high risk.
Depending on your situation, the cleanest approach is to formalise the new dates (and any related changes) in writing - often through a variation document.
Where the contract has an “entire agreement” clause or strict variation process, a properly drafted variation document is especially important.
How To Respond If A Customer Or Supplier Requests An Extension Of Time
If you’re on the receiving end of an extension of time request, your job is to balance commercial reality with risk management. Saying “yes” without conditions can create problems later - but refusing outright can also harm the relationship or push the matter into a dispute.
Start With These Questions
- Is the delay excusable under the contract? (for example, is it caused by your actions or a listed delay event?)
- Have they complied with notice requirements?
- What evidence supports the delay? (emails, timelines, supplier notices, site photos, change requests)
- What’s the actual impact? (does the whole project move, or just one milestone?)
- What are your downstream commitments? (do you have your own deadlines to clients?)
Common Options When Responding
Depending on the contract and relationship, you might:
- Approve the extension of time (with the revised completion date clearly stated)
- Approve part of the extension (e.g. 5 days instead of 10) and ask for a revised plan
- Approve with conditions (e.g. weekly progress updates, revised milestones, additional resources)
- Request more information before deciding
- Reject the extension if it is not allowed by contract or not substantiated
If the relationship has deteriorated and the delay is significant, you may also need advice on whether you have grounds to end the arrangement and what documentation is needed for a clean exit, including a Deed of Termination.
A Note On Waiver And “Course Of Dealing”
Be careful about repeatedly accepting late performance without documenting it. In some disputes (and depending on the contract and conduct), a party may argue that the other side has “waived” strict compliance with deadlines, or that a pattern of behaviour has changed how the contract is applied in practice.
Even if you’re being flexible, it’s often best to confirm in writing that:
- you agree to a one-off extension of time, and
- all other rights under the contract are reserved
This can help you stay commercially reasonable without giving up legal leverage.
How To Build Better Extension Of Time Protection Into Your Contracts
The easiest extension of time to manage is the one you planned for before anything went wrong.
If your contracts are silent (or unclear) on EOTs, you’re more likely to end up negotiating from scratch while the project is already under pressure.
Key Clauses That Make Extensions Of Time Easier
When we help small businesses draft or improve contracts, we often look at including clear clauses around:
- milestones and deliverables (what’s due, when it’s due, and what “completion” means)
- extension of time triggers (what events justify an EOT)
- notice requirements (how and when a party must notify)
- evidence requirements (what information must be provided to support the request)
- mitigation obligations (what each party must do to minimise delay)
- consequences of delay (fees, credits, termination rights)
- interaction with variations (scope changes often require time changes)
Getting the wording right matters, and it’s one of those areas where clause drafting can save you a lot of uncertainty later.
Practical Tips For Your Day-To-Day Contracting
- Use clear dates (avoid ambiguous language like “ASAP” or “when ready”).
- Define dependencies (for example, “Client must provide feedback within 3 business days”).
- Keep a paper trail (especially around scope changes and approvals).
- Align your sales promises with your contract (don’t promise a 2-week delivery if the contract allows 6 weeks, or vice versa).
What If The Deadline Is Set By A Government Process Or An IP Application?
Sometimes an extension of time isn’t just contractual - it relates to a regulatory or administrative deadline. A common small business example is intellectual property (IP), where missing a deadline in an application process can have serious consequences.
In those cases, the process can be more formal, and you may need to lodge a specific request or application with the relevant agency (for example, IP Australia) rather than relying on a simple agreement between parties.
If a deadline affects your brand protection or ability to enforce rights, it’s worth acting quickly rather than hoping it can be fixed later.
Key Takeaways
- An extension of time is a documented change to a contract deadline, and it can help reduce the risk of breach, penalties, or termination when delays occur (depending on the contract terms).
- Always check your contract for notice requirements and delay clauses before requesting (or responding to) an extension of time.
- A strong extension of time request is specific: it identifies the affected deadline, explains the delay cause, shows impact on timing, and proposes a revised date with mitigation steps.
- If you’re receiving an EOT request, you can approve it, approve it with conditions, request more information, or reject it - but be mindful of waiver risks if you repeatedly accept delays informally.
- Clear contract drafting (including variation and extension of time clauses) makes delays easier to manage and reduces the chance of disputes.
- Some extension of time issues are more formal (such as IP or regulatory deadlines), so it’s important to get advice early and follow the correct process.
