You ship software or you sell advice. One day a client says your work caused them a financial loss and points to a clause in the contract. Professional indemnity, also called errors and omissions cover, is the policy that stands between that claim and your bank balance.
Professional indemnity insurance (E&O) covers claims that your professional service, software or advice caused a client a financial loss, whether through a genuine error, an omission, negligence or a missed deliverable. For SaaS, IT services, consultancies and agencies it is often the first cover a customer asks about, because enterprise contracts routinely require it before signing. This guide covers what it protects, who needs it, why the claims-made basis and retroactive date matter, and how it differs from cyber and general liability.
- What it covers
- Claims that your service, software or advice caused a client a financial loss: error, omission, negligence, breach of professional duty.
- Who needs it
- SaaS, IT services, consultancies, agencies and other firms paid for their skill or work product.
- Why buy it
- Often required by customer contracts, and it caps a risk that can otherwise hit the company directly.
- How it is written
- Claims-made basis with a retroactive date; the policy must stay continuously in force.
- Indicative cover
- Often ₹1 crore to ₹5 crore, sized to your contract liability caps (indicative, not a quote).
1 What professional indemnity insurance covers
Professional indemnity insurance responds when a client alleges that your professional work caused them a financial loss. It is built for businesses that are paid for their expertise rather than for a physical product, and it treats the quality of that work as the risk being insured.
A typical policy responds to claims arising from:
- Negligence or a failure to apply reasonable professional skill and care.
- Errors and omissions in your deliverable, code, model or advice.
- A missed or defective deliverable that causes the client a measurable loss.
- A breach of professional duty or breach of contract in how the service was performed.
- Unintentional misstatements or wrong advice that the client relied on.
Crucially, it usually pays two things: the client’s financial loss (damages or a negotiated settlement) and your legal defence costs, which for a small company are often the more frightening number. Even a claim you eventually beat can burn through lakhs in legal fees, and defence costs are exactly what the policy is there to absorb.
2 Who needs it
The simple test: if a client can suffer a financial loss because your work was wrong, late or defective, and can point to you for it, you have professional indemnity exposure. In the startup world that squarely includes:
| Business type | Why professional indemnity fits |
|---|---|
| SaaS and software products | A bug, downtime or a wrong calculation in your product can cause a customer a real financial loss, and enterprise contracts increasingly name PI cover as a condition. |
| IT and development services | You build or integrate systems for clients; a defect, a missed spec or a delayed delivery can trigger a claim for the client’s losses. |
| Consultancies and advisory firms | You are paid for advice. If a client acts on it and loses money, the claim lands on your professional judgement. |
| Design, marketing and creative agencies | A campaign error, an IP slip or a botched deliverable can cause a client loss and a demand for compensation. |
The strongest, most practical trigger is not a founder deciding to be prudent. It is a customer contract. Once you move upmarket into enterprise deals, the procurement and legal teams on the other side will list professional indemnity, alongside cyber, as insurance you must hold before they sign.
3 Match the contract: liability caps and required cover
Enterprise contracts almost always contain a limitation of liability clause that caps what you owe the customer if something goes wrong, often a fixed rupee figure or a multiple of the annual fees they pay you. The same contracts frequently require you to carry insurance of at least a stated amount.
These two numbers should talk to each other. The point of professional indemnity is to stand behind the liability you have accepted in the contract, so the practical rule is straightforward:
If you agree to a liability cap of ₹2 crore in a large contract but only hold ₹50 lakh of cover, you have personally left ₹1.5 crore of accepted risk sitting on the company’s balance sheet. Conversely, buying far more cover than any contract requires is money that could be working elsewhere. Reading the caps first, then buying to fit, is how you avoid both mistakes.
4 Claims-made basis and the retroactive date
Professional indemnity is almost always written on a claims-made basis, and this is the single feature founders misunderstand most. It means the policy that responds to a claim is the one in force on the day the claim is made against you, not the policy you held when you actually did the work.
Two things follow from that, and both matter:
- Continuity is everything. Because only a live policy responds, letting the cover lapse for even a short period can leave you exposed for years of past work. You have to keep renewing without a gap.
- The retroactive date sets how far back you are covered. Your policy carries a retroactive date, and only work done on or after that date is covered. Keep the retroactive date fixed as you renew, ideally on or before the date you first started serving clients, so your history stays protected.
When you switch insurers or renew, guard the retroactive date. If a new policy quietly resets it to today, all your earlier work drops out of cover even though nothing else changed. This is also why, when you wind down a contract or the business, an extended reporting period or run-off cover can matter: it keeps the door open for claims made after the policy would otherwise end.
5 How it differs from cyber and general liability
Founders often blur professional indemnity with cyber and with commercial general liability. They cover different triggers, and a growing software company frequently needs more than one. The line between them is worth learning before a customer contract asks for all three.
| Cover | What triggers it | Typical example |
|---|---|---|
| Professional indemnity (E&O) | Your work, service or advice was wrong and caused a client a financial loss. | A bug in your product miscalculates a client’s payroll and they claim the loss. |
| Cyber insurance | A security incident: breach, hack or ransomware, and its fallout. | Attackers exfiltrate customer data from your systems; you owe breach response and notification costs. |
| Commercial general liability | Third-party bodily injury or property damage, not financial loss from your work. | A visitor is injured at your office, or you damage a client’s property on site. |
The overlaps are real. A single incident, say a flaw in your software that both fails to work and exposes customer data, can touch both professional indemnity and cyber at once, which is exactly why many SaaS companies carry both. Professional indemnity asks “was your work wrong?”; cyber asks “was there a security failure?”; general liability asks “did someone get hurt or have their property damaged?”.

6 A worked example: Brewly and the enterprise contract
The clearest way to see how professional indemnity works is to follow one contract from term sheet to claim.
Brewly Pvt Ltd runs a SaaS platform that helps cafe chains manage inventory and orders. A large listed retail group wants to roll it out across 400 outlets. The master services agreement caps Brewly’s liability at ₹2 crore, and a separate clause requires Brewly to hold professional indemnity cover of at least ₹2 crore for the life of the contract. Brewly’s existing policy is only ₹50 lakh, so the deal is stuck at the insurance clause.
Working through an IRDAI-registered broker, Brewly steps its professional indemnity cover up to ₹2 crore, matching the contract cap, and confirms the retroactive date is held back to when it first went live with customers. Eight months later a pricing bug in the platform overcharges the retailer’s outlets and the retailer claims its recovered losses. Because the claims-made policy is in force when the claim is made and the retroactive date predates the work, the policy responds to the claim and Brewly’s defence costs. Brewly keeps the policy schedule and renewal record on file, because its own investors ask for exactly these documents in diligence.
7 Your professional indemnity checklist
- List your live customer contracts and pull out each limitation of liability cap and any required insurance amount.
- Set your sum insured to cover the largest cap or required amount across the book (indicative range often ₹1 crore to ₹5 crore).
- Confirm the policy is written on a claims-made basis and note the retroactive date.
- Keep the retroactive date fixed on every renewal, ideally on or before your first client engagement.
- Never let the policy lapse between renewals; a gap can strip cover for past work.
- Check whether you also need cyber and general liability, which many contracts require alongside PI.
- Buy through an IRDAI-registered broker and compare cover, exclusions and defence-cost treatment, not just premium.
- File away the policy schedule and renewals for customer and investor due diligence.
