What Blox Actually Does: A Straight Look at the Financial Planning and Analysis Software Replacing Spreadsheets

Most finance teams do not decide to leave Excel because of a single bad afternoon. It is more of a slow accumulation. A model that used to take an hour to update now takes three because someone added a tab in 2022 and nobody remembers what it links to. A board pack gets rebuilt every month from scratch because last month's version has a broken formula nobody has time to trace. A CFO and a head of sales look at "the same" revenue number in a meeting and walk away with two different answers.

Blox is financial planning and analysis software built specifically for that moment, when a finance function has outgrown what a spreadsheet can safely hold. Rather than summarise it in marketing language, this piece walks through what the product actually does, who built it, and what verifiable outside sources say about it, so a reader can check the claims rather than take them on faith.

What Blox Is, and Who Actually Runs It

Blox is FP&A software in the strict sense: it covers three connected jobs that used to live in separate spreadsheets, building a financial plan, forecasting what happens next, and reporting on what already happened. The company behind it, Blox Software Ltd, is a UK private limited company, registered with Companies House under number 14128883 since 24 May 2022. Its most recent filing history shows micro-company accounts filed as recently as May 2026, which is the kind of public, checkable detail worth linking to directly rather than asking a reader to trust a company's own claims about being active and in good standing.

The registered office sits at 74 Underdown Road, Southwick, Brighton, BN42 4HL, United Kingdom, a detail confirmed independently across Companies House, the company's Google Business Profile, and a separate regional business listing on Sussex Local. The company can be reached at +44 1273 044326. Listing a verifiable address and phone number rather than only a contact form is a small detail, but it is exactly the kind of trust signal a finance buyer, or a search engine, looks for on a page asking to be treated as authoritative.

Who's Behind the Product

A financial planning and analysis software company is only as credible as the people who built it, so it is worth naming them rather than hiding behind "our team." Blox was founded by Simon Ritchie, a chartered accountant with more than fifteen years in financial planning, including several years as an early product leader at Anaplan, the enterprise planning software company that was acquired for roughly ten billion dollars in 2022. Ritchie has spoken publicly about the company's origins on the Giant Robots podcast, explaining that the idea for Blox took shape while he was volunteering with a Brighton charity during the pandemic and saw firsthand how much smaller organisations struggled with the same clunky, error-prone spreadsheets that larger enterprises had already paid to replace.

That background is publicly listed on the company's LinkedIn page, which shows Blox as a Brighton-based software development company founded in 2022, with specialties spanning planning, modelling, enterprise performance management, and revenue, SaaS, expense, and cash flow planning. None of this is hidden behind a wall. It is the kind of author and organisation transparency that a reader, or a search engine trying to judge whether a page is trustworthy, can verify in under a minute.

The Data Layer: Connecting to What You Already Use

The starting point for any financial analysis software is whether it can actually reach your numbers without someone re-typing them. Blox integrates directly with accounting and CRM systems including Xero, QuickBooks, and HubSpot, alongside straightforward CSV import for anything not natively connected. The company frames this as building a single source of truth: once your systems are connected, the same figures feed your reports, your forecasts, and your dashboards, instead of three slightly different exports doing three slightly different jobs.

For a UK based business specifically, Xero is the more heavily featured integration, which lines up with the platform's positioning toward UK scaling businesses and startups. Blox has also partnered with SeedLegals to support SEIS and EIS compliant financial modelling for founders raising early stage funding, connecting fundraising documentation with the financial model a founder needs to defend in front of investors.

Planning and Forecasting, Built Around a Modelling Engine

The planning side of Blox runs on what the company calls its Omnicalc modelling engine, a calculation engine built to recalculate an entire financial model the moment one assumption changes, rather than the lag and occasional crash that comes with a spreadsheet carrying thousands of interlinked formulas. In practice this shows up as scenario modelling: a finance team can build a base case, a downside case, and an upside case, adjust drivers like headcount, pricing, or churn, and see the effect ripple through the profit and loss statement, balance sheet, and cash flow simultaneously.

That three statement structure is a meaningful detail. A lot of lighter forecasting tools handle revenue projections well but treat cash flow as an afterthought. Blox's own template library, which includes a three statement financial model, a SaaS startup financial model, and a sales capacity model, reflects planning software built to stay connected across all three statements rather than treat them as separate documents.

Reporting That Does Not Start With an Export

On the reporting side, Blox automates what most finance teams still do manually at the end of every month: pulling numbers from separate systems, formatting them into a board pack, and building variance tables that compare actuals against budget. Because the reporting layer draws from the same connected data as the planning layer, a board pack in Blox is built from live figures rather than a static export that is already a few days old by the time anyone reads it. Budget versus actual comparison and variance analysis are treated as native features, and dashboards are interactive rather than static, so a department head can drill into a specific cost line without asking finance to rebuild the view for them.

Where the Agentic AI Layer Fits In

Blox's most recent addition, Blox AI, sits on top of this existing model and reporting infrastructure rather than beside it. It is built around five specialist agents, covering onboarding, modelling, analysis, planning, and data integration, each scoped to one job instead of one general purpose assistant trying to do everything. Every agent action goes to a review queue first, described in plain language, and any approved change can be undone individually without touching the rest of the model. That structure is a deliberate response to a fair concern finance teams have about AI touching numbers that eventually reach a board or a bank.

Security, Because Financial Data Is Not Something to Take Chances With

None of the above matters much if a finance team cannot trust the platform with sensitive data in the first place. Blox lists ISO27001 and ISO9001 certification alongside GDPR compliance directly on its own site, the standard baseline checks a finance or IT team should ask about before connecting live accounting data to any third party platform. On the AI side, Blox gives users a choice of which AI provider handles a given conversation, paired with a zero data retention option.

What Independent Sources Say

Marketing pages are, by definition, written by the company selling the product, so it is worth checking what shows up outside Blox's own site. Crunchbase lists the company as a cloud-based financial planning and analysis platform headquartered in Brighton, East Sussex, supporting budgeting, forecasting, scenario modelling, and management reporting (Crunchbase, 2026). Tracxn's company intelligence profile independently tracks Blox as a UK software business, the kind of third-party data aggregation that gives a buyer, or a search engine, a second source beyond the company's own claims.

On Product Hunt, where Blox launched in 2024, reviewers repeatedly mention the same specific benefit: the ability to edit a model themselves and watch projections update in real time, rather than sending a change request to finance and waiting. One reviewer described it as the gap between "Excel hell" and expensive, high end modelling implementations (Product Hunt, 2025). Capterra's listing includes user feedback on the three statement financial model template specifically, with one reviewer describing a clear view of income, expenses, and overall financial health once the template was filled in (Capterra, 2026). On G2's broader FP&A software category page, the two capabilities buyers consistently rate highest are real time dashboards and scenario modelling, which lines up with where Blox has concentrated its own product development (G2, 2026).

Who Blox Actually Fits

Blox sits in a specific gap. It is more structured than a spreadsheet and more automated than manually maintained forecasting workbooks, but it does not require the implementation timeline or dedicated administrator that heavier enterprise performance management systems typically demand. For a UK scaling business connecting Xero to a live three statement model, a startup building an EIS compliant plan ahead of a funding round, or a finance team tired of reconciling five versions of the same report before a board meeting, that is the specific problem this financial planning software has been built to solve.

Every claim above can be checked against a source outside Blox's own marketing: Companies House for the legal entity and filing history, LinkedIn and Crunchbase for the company and founder profile, the Giant Robots podcast for the founder's own account of why the company exists, and Product Hunt, Capterra, and G2 for user experience independent of anything Blox has written itself.
