The platform from Hydr provides full invoice financing in just one day. This is made possible by integration compliant with payment terms in the UK.

By implementing a decision engine, as well as transforming the traditional signup process, winning customers and verifying their invoices was reduced from several weeks to just 24 hours.

About the Company

Hydr’s technology enables 100% of invoice values to be funded within 24 hours. The company enables fast and stress-free payment under transparent conditions. Customers don’t encounter hidden costs – fees are fixed, transparent and simple to understand.

All thanks to software that verifies the customer, aggregates data in one place and improves decision-making. In addition, the risks associated with funding individual invoices are significantly reduced.

Mission of Hydr

Hydr wants to eliminate payment terms for small businesses in the UK by providing them access to the cash tied up in unpaid invoices on their balance sheets, by getting them paid for those invoices within 24 hours of creation.

Our Work

The purpose of the cooperation was the development of a platform to facilitate signup, data aggregation and streamline invoice payments.

The Challenge

Factoring services in the UK are considered expensive and unprofitable.

1. Process


The collaboration with Hydr was preceded by a joint workshop in October 2020. The aim of that meeting was to develop actions to improve the process on the customer side as much as possible. Equally important was to prepare the MVP and develop an onboarding scheme that would enable accurate verification of customers. The culmination of the agreed objectives was to automate the process using a special decision engine. After the MVP was successfully launched in June 2021, a second Railwaymen and Hydr workshop was held in October 2021 to clarify further objectives for mutual collaboration.

Communication & Workflow

Communication with the client at each stage to date has been effective. We communicated via Slack messenger and held a project call together once a week. Additionally, along with each milestone, we presented a demo of the system.

2. Features


Customer verification is required to start the invoicing process. For this, a thorough onboarding process is required, which allows Hydr to make the final decision regarding invoice payment.

The onboarding we worked on together consists of 15 steps. The customer entrusts us with their bank and account details (Xero at launch, now QuickBooks, FreeAgent, Kashflow and Sage 200 Cloud)*. On the other hand, Hydr is responsible for verifying the client’s creditworthiness, verifying the identity of the decision makers and ensuring that documents can be signed electronically.

Once the relevant data has been collected, the system carries out verifications, resulting in the final decision. The invoicing stage ensures ongoing checking of data, funding of invoices and insight into whether receivables are paid by the debtor.

* Customer data is protected against any outside interference. Only a limited number of people have access to it in order to ensure the highest security standards.

Decision Engine

The decision engine collects the necessary customer data. Based on this data, it makes funding decisions. However, the final word belongs to the analyst, who checks the solution proposed by the system. This is an innovative approach compared to Hydr’s competitors. In their case, analysts are responsible for most of the verification process. Our approach allows us to offer far greater automation, leading to lower cost to serve and higher margins on the service. Individual reports are made for each client.

The decision-making system makes it possible to determine whether the customer meets all the conditions for cooperation. What’s more, the engine makes it possible to check debtors individually.


The implemented project contains as many as 7 integrations. One of them is cooperation with the Xero accounting software, which streamlines customer verification and the entire invoicing process. A large number of integrations makes it possible to ensure the highest standards of customer security, verification and assessment of creditworthiness and identity.

4. UX/UI


During the onboarding stage, we faced several challenges. One of them was the use of proven external integrations that allow for the secure transfer of sensitive data. In addition, we developed a solution whose role is to verify the company. Also important was the integration of the tool with the bank account and the accounting system. In the case of the accounting system, the company has the possibility of verifying the client, but also its customers, which has a great impact on the final funding decision. One element of the onboarding we created for Hydr is KYC (Know Your Customer), which allows us to verify a customer’s identity before signing a contract. This tool helps to rule out any potential fraud attempts. An important part of this process is the integration with HelloSign, which makes it possible to generate contracts to be signed by all directors.

Simple and Informative Dashboard

After the onboarding process, the customer is given access to the dashboard. The main features are the ability to select customers for factoring and to view processed invoices. This is the customer’s command center, where they can observe the various processes carried out by Hydr. In addition to access to current information, the customer has the possibility to edit data in the dashboard.

Admin Panel

The first version of the system included an initial admin panel, which is now being extended with new functionalities. To this end, together with Hydr representatives during the workshop, we have established an action plan that includes further development. When the invoice, after verification, enters the payment process, a transfer basket is created. These are created by the system together with the managers. In future, this process will be subject to automation.

5. QA

The Quality Assurance process was as time-consuming as the front-end activities. Due to the handling of sensitive data on the customer side, we took care to ensure that it was properly secured at every stage. Equally important for us were integrations with e.g. the banking and accounting system, which also required appropriate testing. The next stage of work will be actions connected with streamlining work in the admin panel.

Final Product

Results & Further Development

The result of our efforts has been to shorten the standard factoring process, which for other companies is 14 days and longer. Hydr’s technology enables this to be completed in just 24 hours. Hydr’s offering is much more competitive thanks to our joint efforts. By automating the processes, the number of analysts previously involved has been reduced. As a result, costs on the customer side have decreased.


“Well we went through a competitive tender process with three software development houses, all of whom were recommended to us from within our network. We chose Railwaymen because we feel like the projects that these guys had worked on before are very much in line with what we are trying to deliver. We’ve built a great rapport with the team, so Łukasz (Railwaymen CEO) was the person that we spoke to initially, and yet we just felt the right fit for us as a business of what we were trying to achieve.”
