Choosing an accountant who understands startup tax, fundraising, and share structuring often means sifting through firms that either lack sector expertise or limit support to basic compliance and year end filings. Many providers do not publish pricing, specialise too narrowly, or cannot guarantee both dedicated advisory and investor-grade reporting as you grow. This comparison details four startup-focused accounting and tax firms in London, so you can select the one that best fits your stage, funding needs and appetite for hands-on support.

Core services start at £249 per month, with a Blue Plan at £549 and a Black Plan from £1,999. Founded in 2013 and London based, the firm concentrates on cloud led accounting for tech startups and on practical funding and R&D tax support.
Price & Accountants pairs day to day bookkeeping with advisory aimed at funding readiness and investor friendly share structuring.
Their stated focus is tailored strategic advisory for early stage tech startups, combining practical funding support with cloud based systems. That pairing aims to remove common friction points when teams prepare for seed or Series A rounds.
Small to medium sized tech startups and entrepreneurs in London who need cloud first accounting plus funding and tax advisory as they prepare for investment rounds. Less suited to founders who want a bare bones, pay as you go bookkeeping only option.
Tiered retainers from £249 to £1,999 let you match service level to funding stage and cash runway. That pricing structure turns advisory time into a predictable budget line as you move from setup to investor engagement.
A London based startup engaged Price & Accountants to set up Xero, prepare R&D narratives for an HMRC claim, and tidy historic accounts ahead of Series A due diligence. The engagement reduced the founders time on finance and produced investor friendly reports.
Core services begin at £249 per month. The Blue Plan is listed at £549 per month. The Black Plan starts from £1,999 per month. Custom packages available for bespoke advisory or complex funding work.

Finerva combines fractional CFO support with advance EIS and SEIS assistance while targeting fast-growing tech, biotech and e-commerce companies, and it expanded capacity through a merger with Rouse Partners. The firm positions itself for founder teams that need investor-ready finance rather than basic compliance.
Finerva focuses on adviser-led finance for scale-ups and offers a mix of retained and project work.
The main differentiator is sector specialisation paired with senior finance resource. Finerva deliberately combines funding-side expertise with ongoing finance operations so founders get one adviser for investor readiness and routine management.
If you are a solo founder or a micro business with only statutory returns and minimal funding intent, Finerva will be a poor match. If you need clear price brackets to compare immediately, the bespoke pricing model will slow procurement.
Ambitious UK founders and scale-up leaders in technology, life sciences or consumer sectors who require funding advice, investor packs and interim CFO capability alongside regular accounting and tax. Best for teams preparing for Series A or handling cross-border scale challenges.
A rapidly growing SaaS business engaged Finerva to tidy its books, secure SEIS advance assurance and provide fractional CFO support through a Series A process. The adviser handled investor reporting, forecasts and the share structure work that reduced negotiation friction with investors.
Finerva does not publish fixed tiers. Pricing is bespoke and tailored to the scope whether that is a retained fractional CFO retainer, discrete funding work or a combined package. Expect a discovery discussion to define deliverables and fees.

Purpose-built for VC-backed technology startups, Onside embeds a dedicated finance team led by Chartered Accountants into scaling companies to handle accounting, tax and CFO support. The offering emphasises fast access to technical tax advice and close Xero integration for reporting clarity.
Dedicated finance team led by Chartered Accountants who act as an outsourced finance function for founders.
Integrated accounting, tax and on-demand CFO support that covers compliance, investor reporting and growth planning.
On-demand access to tax and technical experts and a partnership with Xero for cloud accounting and real-time bookkeeping.
Onside sells itself as an embedded finance partner that pairs hands-on senior accountants with SaaS systems to replace traditional external accounting relationships. Compared with Priceandaccountants, Onside focuses more narrowly on VC-backed tech businesses and embedded FD style support rather than broader SME tax services and R&D claims.
Deep funding ecosystem knowledge helps shape cap table and investor reporting in ways that match VC expectations rather than generic small business accounting.
Tailored support for rapid stages from pre-seed to Series C, so the finance function grows with the business rather than being a stopgap.
Long-term partnership approach means the same senior contacts remain involved, which speeds investor audits and fundraising due diligence.
Combines human expertise with tech-enabled processes, reducing admin time for founders while keeping technical judgement in-house.
Public evidence of third-party reviews is limited, which makes independent verification of long-term client outcomes harder.
No published user scores or curated testimonials are available, so procurement teams must rely on direct references.
The service may set higher expectations for startups that only need basic compliance rather than strategic advisory.
If you only require low-cost year-end filings and monthly bookkeeping without strategic CFO input, Onside will feel like overkill. The model suits teams that want proactive financial partnership rather than one-off tax returns or purely transactional bookkeeping.
Onside lists a partnership with Xero as a core integration for bookkeeping, bank feeds and live reporting.
Founders and senior finance leaders at VC-backed technology startups who want an embedded finance function. Best for teams that need fast investor-grade reporting, regular CFO advisory and a close working relationship with a single finance team.
A Series A technology company engages Onside to replace several contractors and consolidate investor reporting. Onside provides a named finance lead, monthly management packs in Xero, and ad hoc tax advice for funding rounds, freeing founders to focus on product and hiring.
The product data lists pricing as “Not applicable — informational only”. Onside does not publish standard tiers; pricing is provided via bespoke proposals and retainer arrangements aligned to the level of CFO involvement.

Client packages include direct access to investor introductions and additional client benefits aimed at supporting fundraising and growth. This approach pairs traditional accounting deliverables with warm intros that matter when you are preparing to raise in the UK market.
Jump sells a combined advisory plus connector model that centres on hands-on, founder-level support. Unlike Priceandaccountants, which positions itself as an outsourced Finance Director for tech companies, Jump focuses more tightly on early-stage founders who need bookkeeping, tax filings and targeted investor introductions alongside advisory.
If you need rock-solid, enterprise-grade consistency during high-stakes events such as an imminent funding close, Jump’s variable service record above may be a concern. Also avoid Jump if you require a full outsourced FD relationship with treasury-level modelling and fundraising roadmaps.
Founders and small business owners in the UK who want a dedicated accounting contact plus proactive advisory and introductions to investors. Best for teams that value a personal relationship over a fully automated platform or large-firm uniformity.
A London tech startup preparing for Series A uses Jump for ongoing bookkeeping, tax filings, business valuations and investor introductions. Founders reported reduced time on admin and clearer next steps during fundraising while advisers handled compliance and introductions.
Pricing is not published in the product data and is treated as informational only. Expect bespoke quotes based on company size, transaction volume and advisory needs; contact Jump Accounting for a tailored proposal and fee schedule.

Finerva specialises in delivering fractional CFO expertise combined with EIS and SEIS planning, pairing operational finance with advanced funding strategies. Its bespoke pricing may seem opaque but allows alignment with unique scaling challenges.
