One-stop solution for accounting needs: Accountants for Startups!
Lay your startup foundation with 123Financials

Launching a business can be a life-changer. But, it comes with risk and uncertainty from the cut-throat competitive industry. Before entering the market, there's a lot to be done.

Your startup accountant validates your idea and long-term goals concerning the market structure and devices a strategy to maintain uninterrupted cash flow. We have a buddy for you whom you can trust for any finance-related advice. We have everything a startup needs under one umbrella.

Not that techie? Need a hand?

Old-school accounting methods are given up these days. With the unnumbered advent in the technical sector, startup accountants are resorting to high computing software such as Xero, Quickbooks, and FreeAgent.

If you aren't much inclined toward technical advancements, that doesn't mean you will be left behind. Without strategies and processing, raw data is just a load. Hiring a tech-savvy startup accountant is an easy solution for utilising cloud-based software.

Lots of registrations? Let's apply as a team

Great Startups are lean and run on flexibility and freedom, yet compliance is necessary. Countless registrations with government bodies with supporting documents in the required formats are needed. Well, this will certainly make you tired.

Sounds overwhelming? Nevermind! Your startup accountant can register for the VAT, Payroll, EIS/SEIS, Cap tables, R&D tax credits, Pensions, etc. They even keep you in a circle until the processes are concluded.

Short on funds? It's time to shoot a fundraiser session

Startups usually depend on the funds raised during the pre-seeding or seeding round. Bootstrap startups where the founder makes the entire investment are rare to find.

With the industry getting competitive day by day and great startups kicking off, it is a tough race to seek investments. You must be very precise with the company's evaluation.

Evaluation can be ambiguous, but our startup accountant has in-depth knowledge of the industry with which they bring out the sharpest and most detailed evaluation for your fundraisers. Once you hire a startup accountant, the evaluation and supporting documents are just a ping away.

Know nothing about EIS/SEIS? We are there for you

As your startup sets foot in the market, you might need some additional funds. EIS (Enterprise Investment Schemes) and SEIS (Seed Enterprise Investment Schemes) are some of the available solutions making your startup attractive to UK taxpayer investors.

It becomes a mere task to seek some funds for startups with the tax benefits associated with these schemes. We know the start and end of these programs, and the startup accountant can assist you in wrapping up the mandatory paperwork.

Make up your mind; we are just a ping away

Great things take time, and significant decisions need some action. You can ping us now with the accounting vulnerabilities your startup is facing, and our team will get back with a promising solution for all your startup accounting pitfalls or queries.With many endeavors, our startup accountants strive all day and night to do their client's a good turn.

Let's discuss the services that we offer to back your startup

It is a myth that one employee can't make a difference in sales and revenue. Hire a professional startup accountant, and you will notice the revenue trajectory of your startup going steeper and higher. Once the startup accountants are on board, you will have someone to look upon for financial guidance.
