Landing that first client is a major milestone for any business, but when your business is a software company, it’s also the moment you’re most exposed to real commercial risk.
To protect your business you should, as a minimum, have professional indemnity (PI) in place for the date the client contract starts.
Here’s why.
You’re immediately liable
The minute a customer relies on your software, you’re accountable for performance, accuracy and delivery.
If something goes wrong, they can claim financial loss. As an early‑stage company, that’s likely to be unaffordable for your business.
Risks beyond beta testing
You can test new software again and again but even after your final beta tests are complete some gremlins won’t appear until it’s rolled out into the real-world.
No one wants to hear it, but your first client is the guinea pig and it’s likely things will go wrong. Your client won’t necessarily complain or bring litigation, but this is where your fledging business is at most risk
Understanding your policy
If you’re working Most PI contracts will have a start date and a retroactive date (the earliest date for which cover applies).
A new policy will only cover work from the date you first take out PI insurance. If you sign contracts before your retroactive date, there’s a chance claims arising from incidents before that date will be excluded.
Enterprise clients expect it
Most larger organisations will require your business to have PI cover as part of vendor onboarding. Having it in place early removes friction from sales cycles and positions you as a credible, reliable firm.
Reassurance for your investors
Having PI insurance in place signals operational resilience and shows you understand risk.
It protects your company’s future and reassures investors that a single dispute won’t derail the business.
The good news
PI insurance for software businesses – regardless of whether it’s SaaS, custom development or integrations – is usually low cost and will give broad protection (if you choose a high-quality product).
Put it in place before signing your first client to protect cash flow, build trust and crucially ensure all client contracts are protected from the outset without gaps.
