Thinking About Outsourcing Your Finance Functions To Us?

Here’s Everything you need to know to make a decision

Who we support

Thrive specialises in early-stage B2B tech businesses. We help tech founders from pre-seed through to series B avoid the stress of hiring by filling the gaps in their finance system.

If like us, you’re a fast-growth tech company, looking for hands-on knowledgeable and responsive accountants who can do it all, then I would massively, massively recommend Thrive.

Will Read, CEO Sideways 6

What we help with

Other firms are mostly built to do accounting, tax and payroll only. Thrive is built for 40% of that. We are industry experts, highly skilled in the financial operations of a B2B tech business. Our focus is on creating a finance function – we join up all the financial roles you need so your support is all under one roof.

We offer services to help with the following:

Accounting & Bookkeeping
Planning & Reporting
FinOps & Payroll
R&D & Tax

Thrive has managed our clients’ R&D since 2014 as part of their full-finance-function service. Having the R&D impact considered as we make business decisions, that’s how to truly maximise a claim!

Peter Wallace, Portfolio CFO

What makes us different

Thrive is a certified B-corp. We’re on a mission to show SMEs there’s a strong business case for embracing a more sustainable approach. We believe there’s no need for a trade off between purpose and profit.

You can expect that every interaction with us will contribute to a greater purpose, from booking a meeting to being a part of our yearly donations.


See our strides towards achieving net zero

We’re getting a lot more than accounting advice here. We’re feeling confident that the financial side of our business is being expertly handled, and that, to me, is invaluable.

Satish Jayakumar, COO Increasingly

How the relationship works

You get a whole finance team you can rely on at a fraction of the cost.

The Thrive team is a group of like-minded senior finance professionals. Each of us has our own story of experience, in industry or in practice – from big business commercial finance teams to mid-size accounting firms.

Your team setup:

You’ll be assigned an experienced client manager as your day-to-day contact.
They’ll work alongside a finance assistant who’ll be in touch about bookkeeping queries.
You’ll have expert support from James, Thrive’s founder on specific services.

How we price

Prices can start as low as £200 a month + VAT if you’re just starting out. We won’t give you a one-size-fits-all cost, because every business is in a different place. Together we’ll assess where you’re headed, and give you a proposal tailored to you.

Our quotes are completely bespoke to your needs.
We’re clear and transparent about our pricing upfront – no surprise bills.
We provide a fixed monthly fee (agreed in advance) so you know exactly how much you’ll pay for each service you choose.
Our fixed monthly cost compares incredibly well to the expense and hassle of finding part-time or full-time people in-house to fill every finance role.

P.S. The handover from your previous accountant is simple

Switching from one accountant to another doesn’t come with the pressure or hard work you might be imagining. If you’re already on Xero, that’s 80% of the job done! 15% of the job is accountants behind the scenes. There are only a few things needed from you, mostly signatures and opening mail. You can rest easy knowing the majority of the task is taken care of.
