Startup founders ♥ Standard Ledger
Building a startup is hard. Figuring out your finances shouldn’t be. From capital raising to exits, we’ve helped founders make the right moves – faster and with less stress.
“Closing our £2.5m round with Octopus Ventures was a huge milestone for HealsGood AI. Standard Ledger were instrumental throughout the process – helping us stay investor-ready, manage due diligence and present a clear financial story. They brought real structure and focus, which made a complex raise feel controlled and achievable. Having that level of financial leadership on our side gave us the confidence to move fast and negotiate from a position of strength.”

Jack Henderson
“Standard Ledger saved us from trouble during our UK setup. They turned around crucial work in 48 hours, preventing fines. Having the support you can trust, who knows what they’re doing, means less stress and frees up a lot of mental space.”

Peter Cole
“Standard Ledger was incredibly helpful in reviewing and modelling our finances. Thanks to their support, we reshaped our strategy and identified areas for growth. We are now ready for expansion into new sports and markets.”

Iggy Jovanovic
“John and the team have really understood our R&D story from day one, and have always had a plan for it. We’re in the third year of working together now, and it’s been really great.”

Nadun Hennayaka
“We didn’t hesitate to outsource our Company set up to Standard Ledger. Knowing that they’ll let us know what’s needed, where to sign and what to do is a huge weight off our shoulders. Our bank even commented on how well set up our documentation was!”

Gemma Clancy
“Having Standard Ledger manage bookkeeping has freed up a lot of time. It means I spend less time worrying about money and more time thinking about the bigger picture.”

Getting SEIS or EIS Advance Assurance shouldn’t be complicated or costly. We offer fixed, upfront pricing, so you know exactly what to expect – no surprises.
SEIS Advance Assurance
Advance assurance from HMRC that your company qualifies for the Seed Enterprise Investment Scheme (SEIS). Secure tax relief for early-stage investors, helping you raise pre-seed funding faster.
EIS Advance Assurance
Advance assurance from HMRC that your company qualifies for the Enterprise Investment Scheme (EIS). Give investors confidence in your scale-up with tax incentives designed for growth-stage funding.
How SEIS/EIS Advance Assurance works

The SEIS and EIS are UK Government initiatives that offer tax relief to investors in early stage companies.
We’re talking substantial tax relief, including:
- 50% income tax reduction (SEIS)
- 30% income tax reduction (EIS)
- Capital gains tax exemption (SEIS and EIS)
So, while it’s not mandatory, you can see how SEIS/EIS Advance Assurance from HMRC makes your startup dramatically more appealing to investors.

What if you need more support?

What if you don’t have the business plan and financials that HMRC want to see?
Don’t worry. We’ve got you covered, when others haven’t.
If you don’t have the business planning and financial documents you need for HMRC to grant you Advance Assurance, we can create them for you.
First though, we’ll start with a questionnaire to see if you’re eligible for SEIS/EIS. Then, we’ll chat about what you have and what you might need, in addition to our standard Advance Assurance service.
We’re all about no surprises so if there will be additional costs, we’ll chat about them first, before going ahead.

How much does SEIS or EIS advance assurance cost?
Both SEIS and EIS advance assurance cost £300 each (excluding VAT). It’s a fixed price, so there are no surprise fees or hidden costs.
What's the difference between SEIS and EIS for my startup?
SEIS is for very early-stage companies – you need fewer than 25 employees, less than 3 years old, and under £350,000 in gross assets. EIS is for slightly more established startups with fewer than 250 employees, less than 7 years old, and under £15 million in assets.
Why should I bother getting SEIS or EIS advance assurance?
It makes your startup far more attractive to investors by giving them substantial tax relief – 50% income tax reduction for SEIS and 30% for EIS, plus capital gains tax exemptions. Basically, it helps you raise funds faster because investors get confidence from HMRC that they’ll qualify for these tax benefits.
What if I don't have a business plan or financial documents for HMRC?
No worries – We can create them for you. We’ll start with a questionnaire to check your eligibility, then discuss what additional documents you need beyond the standard advance assurance service. We’ll chat about any extra costs upfront before going ahead.
