Built around SaaS and technology

Growth moves quickly. Your finance needs to keep up.

Recurring revenue, hiring plans and investor expectations create pressure long before year-end accounts reveal it. Addition gives you clear, current numbers while there is still time to act.

01

Runway can change quickly

Hiring, product investment and slower collections can materially change your cash position between reporting periods.

02

Recurring revenue is complex

Subscriptions, upgrades, discounts, refunds and annual contracts make it harder to understand true performance.

03

Investors expect answers

Boards and funders want dependable forecasts, clean reporting and a clear explanation of the numbers behind growth.

04

Systems multiply as you scale

Billing, payments, payroll, expenses and accounting data can quickly become fragmented across different platforms.

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.
