Raising
The metrics investors will test
Net revenue retention, gross margin, CAC payback and the magic number. A SaaS business is valued on these as much as on revenue, and they need to be defined consistently and reconcilable to the accounts before anyone else audits them.
Pricing and packaging
Pricing changes are the fastest lever in SaaS and the easiest to get wrong. We model the effect of a change across the existing base, including churn risk on repricing, before it is announced.
Raising
A model that holds up under questioning, a data room that answers before it is asked, and a clear use of funds tied to milestones. That is what shortens a round.

What Our Clients Say
“Accotax have been our accountants for many years now. We maintained them because of their professionalism. In the last couple of years I have been working with Imran, who has been very professional and helpful in guiding us through the whole process, explaining and clarifying every aspect of it. Very prompt in responding to questions and patient with us even when we seem to be slow.”
“We worked with a few different accountants before finally settling with Accotax, and we're really glad we did. They take the time to understand how our business works and what our needs are. Anum, who looks after our account on a day-to-day basis, including reconciling invoices and preparing the annual accounts, is amazing, professional, efficient, and follows the processes we have put in place together. Accotax has made our accounting experience much smoother and easier. We see them as a long-term partner as our business continues to grow. I would 100% recommend them.”
“I've been working with Accotax since January 2024, and their support has grown alongside my business needs. My personal allocated manager, Umer, provides tailored services for both of my companies, adapting as I expand and ensuring everything runs smoothly. They are responsive, knowledgeable, and always clear in their communication. Their help with accounts, VAT, payrolls, pensions and compliance gives me real confidence and peace of mind.”
