A Document Management System that Saves Octopus Investments £400K a Year

In this document management system case study, we walk through how Euristiq engineers partnered with a London-based investment company to replace manual paperwork with a cloud-based document management system — and why that decision now saves the client an estimated £400K annually.

Overview

Our client is a large investment company based in London. Virtually every facet of their operations has to be backed up with contracts, letters, or documents. Manual management of this task is not only exceedingly arduous but also financially burdensome. To tackle this issue, Euristiq engineers collaborated with the client to devise an automated document management software tailored to their internal systems, delivered through our cloud development services.

The solution uses the company’s internal services, aggregating data from different sources and composing variously structured letters, documents, and even brochures. Because the data is highly sensitive — private financial information spanning finance, property, healthcare, renewable energy, and charity projects — the build demanded special attention to security from day one.

01. PROBLEM

About the legacy document
workflow Euristiq modernized

The client leads multiple projects across finance, property, healthcare, renewable energy, and charity domains. Managing the paperwork behind each one manually — drafting, formatting, and distributing letters and contracts by hand — had become excessively time-consuming, error-prone, and costly to sustain at scale.

Manual document creation across departments

Letters, contracts, and brochures were assembled by hand, department by department, with no shared system pulling data from a single source of truth.

Highly sensitive financial data

Every document carries private financial information, so any new system had to meet a high security bar from the first line of code.

No cloud accessibility

Generated documents lived locally or in email threads, making them hard to retrieve, share securely, or hand off to third parties like print vendors.

Scaling pressure across five business lines

As the client’s project count grew, the manual process couldn’t keep pace with the volume or the variety of documents required.

What is a cloud-based document management system?

A cloud-based document management system (DMS) generates, stores, and secures business documents on cloud infrastructure instead of on-premise servers or manual files. It pulls data from internal services, assembles structured letters, contracts, or reports automatically, and makes them accessible to authorized users from anywhere. For financial companies handling sensitive data, a cloud DMS also adds audit trails, access controls, and encryption that manual or on-premise systems typically lack.
METHODOLOGY

How we applied our 4D approach

01

Discover

Within the first two weeks, Euristiq engineers integrated into the client’s team and mapped how documents moved — and got stuck — across finance, property, healthcare, renewable energy, and charity workstreams.

02

Decide

We chose an event-sourcing / event-streaming architecture over a simpler CRUD approach, trading initial complexity for the scalability and auditability the client’s compliance needs required.

03

Design

The server architecture was designed for high-concurrency operation from the outset, with document access scoped so third parties — like external print vendors — only ever see what they’re authorized to view.

04

Develop

Frontend and backend were built in parallel on .NET Core and Microsoft Azure, with Fluid.Core and WeasyPrint handling document templating and generation, and Kafka/RabbitMQ carrying events between services.

02. SOLUTION

A cloud-native document
generation platform, built to scale

Rather than digitizing the old process as-is, Euristiq’s cloud-based document management software development replaced it with an automated system that forms request and response letters on its own — eliminating manual document creation and speeding up information sharing across departments.

Digitalizing document workflows for an investment company

In just two weeks, Euristiq engineers started delivering results while simultaneously supporting two other projects for this client. Together with the client’s team, we co-created a cloud-based document management system that generates request and response letters automatically, removing laborious manual work and speeding up information sharing across finance, property, healthcare, renewable energy, and charity projects. Storing documents in the cloud also helps prevent fraud and drives meaningful cost savings in document management overhead.

A high-concurrency, scalable server architecture

The cloud DMS runs on a fully designed server architecture built by Euristiq engineers. Generated documents are stored in the cloud and accessible to authorized users at any time for sending, printing, or review — including the client’s printing partner, which can pull only the documents it’s authorized to view from a dedicated folder. Following best practices, we implemented a reliable, highly scalable, and maintainable architecture based on widely used event-sourcing and event-streaming patterns.

Automated generation of sensitive financial documents

Financial and investment companies need to respond quickly to market shifts, and automated document generation is a valuable asset in doing so. The system pulls data from internal company services to compose differently structured letters, documents, and even brochures. Given the sensitivity of the underlying data, the software incorporates enhanced security measures throughout — from access scoping to encrypted storage.

03. RESULTS

£400K+ a year back, and
a system built to keep scaling

Cost

£400K+ saved annually

This digital transformation is estimated to save the organization more than £400,000 a year in document management costs.

Automation

Manual document generation eliminated

Automated document generation replaced hand-assembled letters, contracts, and brochures across five business lines.

Security

Fraud prevention, in production

The cloud-based DMS is deployed and actively used in production, with scoped access preventing fraud and unauthorized document exposure.

How much can automating document
management save a financial services company?

Savings depend on document volume and how manual the prior process was, but they are substantial for firms with heavy paperwork. In this case, Euristiq’s cloud document management system is estimated to save Octopus Investments more than £400,000 a year by eliminating manual document creation across five business lines — finance, property, healthcare, renewable energy, and charity — and cutting the staff time previously spent assembling letters and contracts by hand. If your finance or ops team is still stitching together contracts and letters by hand across multiple business lines, this is the same problem — already solved.

Modernizing legacy document workflows
for a fintech or investment firm?

Whether you’re evaluating build-vs-buy for document automation, preparing for a compliance audit before your legacy system gets flagged, or ready to scale document workflows across departments — we’ve shipped a production cloud DMS that saves a client £400K+ a year. Let’s talk.

What is legacy document management modernization?

Legacy document management modernization is the process of replacing manual or on-premise document handling — paper files, shared drives, or outdated internal tools — with an automated, cloud-based system. It typically involves re-architecting how documents are generated, stored, and secured, migrating existing workflows to event-driven cloud infrastructure, and building in the compliance and security controls that regulated industries like financial services require.
