Expert Financial Support. When You Need It.

A fractional Finance Lead inside your business who takes full ownership of the day-to-day, backed by Addition’s expert team and software.

Our CFO plan gives you a seasoned pro to advise and help achieve your growth goals, without the hefty price tag.

A fixed-fee, fast-turnaround package that gets your financials, pitch deck, and compliance investor-ready in weeks - not months.

If you're building an innovative business in the UK or US
(a product, a system, a way of doing things), then you might be owed tax credits.

We provide accurate, HMRC-compliant valuations to support option grants and ensure your scheme is set up on solid financial ground.

We’ll handle your ERS Annual Return from start to finish, ensuring everything is filed accurately and on time so you can focus on running your business.

We’ll prepare and submit your SEIS/EIS Advanced Assurance application to HMRC, making sure your business qualifies and giving investors the certainty they need to commit.

We take care of payroll, payments, and compliance so your team gets paid accurately and on time - in one click. Perfect for growing teams that want smooth, reliable operations.

Not everything fits neatly into a package - and that’s okay. If it’s finance or accounting related, chances are we can help.
