• Robinsons Packaging plc

DynamicDocumentAPI's answer:

Dynamic Document API is a young product. Our users are mostly developers and small SaaS teams, and we don't name customers without their permission.

TrackZero.eco's answer

TrackZero is built with four different audiences in mind:

• SMEs and mid-market UK businesses facing procurement pressure, tender requirements, or investor questions on emissions. Often producing their first proper carbon inventory.

• Sustainability, finance and procurement leads at larger UK organisations who need audit-ready reporting for SECR, UK SRS or CSRD without a six-figure consultancy engagement.

• Carbon consultants and ESG advisors who run client portfolios and need a platform their clients can also use directly, so the work isn't locked to one relationship.

• Public sector suppliers meeting PPN 006 requirements to bid for NHS or central government contracts over £5 million.

Sectors range across construction, engineering, manufacturing, financial services, food and drink, professional services and technology.

DynamicDocumentAPI's answer:

Developers and product teams whose software has to send documents: invoices after a payment, certificates after a course, reports, labels and statements. Typical users are SaaS companies, marketplaces, e-commerce and learning platforms. A second group are businesses in Germany and the EU that need compliant e-invoices (XRechnung, ZUGFeRD) for the German B2B e-invoicing mandate and public-sector buyers. No-code builders use it through Zapier, Make and n8n, and teams building AI agents use the MCP server.

TrackZero.eco's answer

TrackZero is the UK-built carbon management platform simple enough for in-house teams without the expertise, and powerful enough for experts to work smarter without the cost. Four things set it apart from the crowded field of US and Nordic platforms:

• UK-native by design. SECR, UK SRS, PPN 006 and CSRD reporting are built in, not bolted on. Every output maps to a real UK obligation, so finance teams can hand a report straight to their auditor.

• Collaborative supply chain engagement. Scope 3 is the hardest part of any inventory. TrackZero turns it into a network effect: your suppliers use the platform to submit primary data on their own footprint and the goods and services they sell you. That data flows into your inventory automatically, replacing spend-based estimates with verifiable primary figures.

• You keep the platform, whoever runs it. Use TrackZero yourself or bring in a carbon consultant. If you change consultants, you keep the platform and every year of data in it. .

• Priced to stay affordable at any scale. From SMEs producing a first footprint to listed PLCs preparing for external assurance, the pricing works. No enterprise minimums, no consultancy-tier gatekeeping.

DynamicDocumentAPI's answer:

It covers the whole path from data to finished document in one API: you design a template in a visual or HTML editor (or send raw HTML, CSS or Markdown), send JSON, and get a PDF or image back. The same service also creates e-invoices (XRechnung, EN 16931, Factur-X / ZUGFeRD) that are validated against the official rules before they are returned, and can embed them in the PDF. Rendering is deterministic: the same template and data always give the same document, laid out by a headless browser, with no AI model generating content. Everything runs in the EU (Germany). It also ships an MCP server, so AI agents like Claude and ChatGPT can render documents directly.

TrackZero.eco's answer

Because TrackZero delivers what most carbon platforms only promise: audit-ready numbers without the enterprise price tag, consultancy tie-in or the hidden calculations.

Compared with the big US and Nordic platforms, TrackZero is built for UK regulatory reality first: PPN 006 for public procurement, SECR for large companies, UK SRS for the incoming disclosure standard, and CSRD for UK subsidiaries of European groups. Every calculation is transparent, so auditors review evidence directly in the platform rather than rebuilding numbers.

Compared with free tools, TrackZero adds multi-year tracking with year-specific emission factors, market-based Scope 2, full supplier engagement for primary Scope 3 data, and ISO 27001 certified security.

Compared with the "carbon consultant with a spreadsheet" approach, TrackZero gives you a platform you own. Change consultants without changing tools.

DynamicDocumentAPI's answer:

Most document APIs do one thing: convert HTML to PDF, or fill templates. Dynamic Document API does both, adds image templates, PDF merging and validated e-invoices, and offers them through a REST API, SDKs for Node and Python, Zapier, Make, n8n and an MCP server for AI agents. Data is processed and stored in the EU only, files come back as signed links that expire, and storing nothing at all is a supported option. Pricing is predictable: one published credit table, the same core features on every paid plan and a spend cap you control. We also publish a render-time benchmark with its method and raw data, so you can check our speed instead of trusting a claim. The free plan includes 50 renders a month without a credit card.

TrackZero.eco's answer

TrackZero was founded in October 2023 by people who had done this before. Alan Wilson (CEO) co-founded MoreTrees, acquired by THG PLC within six months of launch. Alan also co-founded Expandly, acquired by GEE. Oliver Waters (CPO) founded Momento, named Apple's App of the Year Runner-Up in Europe. And, Steven Waterfall (CTO) brought engineering leadership from multiple startups.

The idea came from conversations with sustainability, procurement and supply-chain teams through 2023. The same story kept coming up: enterprises sending carbon questionnaires suppliers didn't understand, consultants too expensive to scale and data too inconsistent to act on. One logistics business had lost a contract because it couldn't answer a carbon questionnaire during procurement. Carbon reporting had turned into a condition of doing business, and no one had built the infrastructure to make it work for both sides.

Cranfield University came in early as strategic advisor, pre-seed investor and eventually a customer through its Ready for Net Zero programme. Their sustainability academics validated the methodology against GHG Protocol standards and DEFRA emission factors before the first enterprise customer signed on.

Development began January 2024. The first commercial version launched in March 2024. Bridgestone Tyres signed early and Volkswagen Group UK followed. Today TrackZero boasts organisations from FTSE-listed manufacturers to sole traders and city councils.

DynamicDocumentAPI's answer:

Almost every product eventually needs to produce documents, and most teams end up building their own rendering stack: a headless browser, fonts, page breaks, storage and retries. It works until an invoice splits a table row or a certificate shows the wrong date, and then it becomes a support ticket. We built Dynamic Document API to be that layer for them: templates, rendering and delivery as one service, hosted in Europe, treating pagination, fonts and formatting as engineering problems rather than edge cases. When e-invoicing became mandatory for B2B in Germany, we added validated XRechnung and ZUGFeRD output, and with AI agents producing more paperwork, an MCP server followed.

TrackZero.eco's answer

TrackZero is built entirely in-house by the Track Zero Labs engineering team, led by CTO Steven Waterfall. Nothing is white-labelled, and no part of the carbon-accounting engine is licensed from another provider.

At the core is our proprietary emissions calculation engine, aligned strictly to GHG Protocol standards. Cranfield University's sustainability academics validated the calculation framework against those standards and against DEFRA emission factors before the first enterprise customer came on board.

The platform is a web-based SaaS running on cloud infrastructure, engineered to ISO 27001 information security standards. Every calculation is fully traceable, so auditors and finance teams can review evidence, methodology and figures directly in the platform rather than rebuilding numbers from scratch.

Building the engine ourselves rather than licensing one gives us three things: full control over how methodology evolves as standards update and the ability to expose the workings to customers and auditors instead of hiding it.

DynamicDocumentAPI's answer:

Rendering runs in Rust workers that drive headless Chromium over the DevTools protocol, with MiniJinja for templates. The API and control plane are built with Django and Django REST Framework, with Celery, PostgreSQL, Valkey and NATS JetStream for queues and events, and S3-compatible object storage for files. PDF/A output is checked with veraPDF and e-invoices with the official KoSIT validator. The dashboard and website are built with Next.js. Everything runs on Kubernetes in data centres in Germany.
