Addition are my 'on tap' bookkeepers and financial advisors. I have saved so much time and money switching my basic bookkeeping to them, and I have also utilised them for an R&D claim at half the price of others on the market.
Adam
They really are so incredible - they help us with all of our requirements from payroll to forecasting to budget creation to all end of month and end of year reporting and even R&D tax. Absolute lifesaver for our company and the team is second to none !
Michael
Addition have been great in supporting our growth since opening, and now helping build our development plans. It would have been a much more difficult journey without them!
Laura

Sarah
I cannot express enough how amazing Addition's services are. From the moment I reached out to the team, I knew I was in good hands. The customer service was outstanding, and the entire process was incredibly smooth.

More than accounting.
Everything your business needs to run finance properly.
Addition brings your day-to-day accounting, finance operations, reporting and strategic support together in one connected service.
Accounting foundations
Reliable bookkeeping, VAT, payroll, annual accounts and tax compliance - handled accurately and on time.
Financial visibility
Up-to-date management accounts, cash-flow reporting and dashboards that show what is really happening.
Finance operations
Smarter invoicing, payments, credit control and workflows that reduce admin and keep finance moving.
CFO and strategic support
Forecasting, funding support and experienced financial guidance when your decisions carry more weight.
From reporting the past to managing the future
Compliance keeps you legal. Financial management keeps you in control.
Addition does both - keeping the records right while helping you understand cash, protect margin and plan what comes next.
The financial reality of growth
A growing, profitable business can still run out of cash.
VAT, PAYE, Corporation Tax, payroll, suppliers and slow-paying customers all compete for the same cash. Good financial management helps you see the pressure early and act before it becomes a problem.
Sales are growing. Why is cash tighter?
More revenue can mean more stock, a larger payroll, higher tax liabilities and more money tied up in unpaid invoices.
Plan for the cash growth consumes.
Can we afford the next hire?
Salary is only part of the cost. Employer contributions, onboarding, timing and the effect on runway all matter.
Hire with the full financial picture.
Are we actually making enough margin?
Supplier increases, discounting, delivery costs and overhead creep can quietly erode profit - even when sales look healthy.
Protect margin before it disappears.
What happens if sales slow down?
A useful forecast shows how long cash lasts, which costs can move and when action is needed.
Know the options before pressure hits.
