Fintech software

Fintech software development

Build financial software that makes transactions and money workflows easier to understand. Our work covers expense tracking, financial message processing, payment journeys and customer interfaces connected to the services behind them.

The operational challenge

Connect the work behind fintech

Financial information often arrives through different channels and in inconsistent formats. Users need clear records and status messages, while operating teams need to trace where data came from and resolve incomplete or conflicting inputs.

Workflows we can scope

Software shaped around fintech operations

These are starting points for an engagement. We define the exact scope around your team, business rules and existing systems.

01

Transaction data processing

Convert agreed financial inputs into structured records, with source references, duplicate handling and an exception path when a message cannot be interpreted reliably.

02

Personal finance experiences

Bring expenses, categories, budgets and savings goals into clear user journeys. Explain what a figure includes and make corrections easy to review.

03

Payment journeys

Connect payment initiation to provider-supported flows. Distinguish an initiated request from a confirmed payment and design clear pending, failed and recovery states.

04

Operational investigation

Give support teams the information needed to investigate parsing failures, integration errors and inconsistent records without exposing unnecessary customer data.

BeeWise mobile app

A clearer picture of everyday money.

Our BeeWise work brings transactions, budgets, savings goals and shared expenses into a connected mobile experience.

BeeWise

From daily spending to the bigger picture.

A monthly overview makes income and expenses easy to compare. Categorised transactions help people understand where their money goes, while budgets and savings goals keep the next step visible.

  • Monthly activity and transaction categories
  • Budgets, savings goals and shared expense splits
  • SMS-assisted expense capture on supported Android devices, with user permission

Finance SMS parser

Turn bank alerts into useful financial records.

Behind BeeWise, our finance SMS pipeline connects mobile message collection with bank-specific parsing, template review, categorisation and duplicate detection.

Fictional message and sample output. Processing depends on supported senders and accepted bank templates.

Every record has a path back to its source.

  1. Collect & queueFilter recognised financial senders on Android and store alerts in a persistent local queue for upload.
  2. Check & extractResolve the bank, select its parser and check the template before accepting a financial record.
  3. Categorise & reconcileExtract financial fields, assign merchant-based categories and check for duplicates within the user’s records.

Unknown templates enter a review workflow and can be replayed after acceptance. Non-financial alerts stay outside the transaction feed.

Design and integration decisions

Resolve the details that affect daily use

Data provenance

Record the source and processing state of financial inputs. Make corrections traceable and define how duplicate or late-arriving records are handled.

Access and consent

Scope permissions and data collection around the product journey. Define what information is retained, who can access it and how it is removed.

Provider boundaries

Review authentication, callbacks and failure behaviour for each connected service. Confirm which system supplies the authoritative transaction status.

Relevant portfolio

Explore our work in fintech

BeeWise brings expenses, budgets and shared splits together. Split UPI supports reviewed payment initiation, while Super Calci provides an offline-first calculator experience. These examples show distinct financial product journeys.

From workflow to release

Make the first release useful to the people running the operation

01

Understand the work

Map the current process with its users, records, handoffs and exceptions. Choose the bottleneck the first release should address.

02

Define the rules

Agree roles, data ownership, integrations and acceptance examples. Check the cases that cannot follow the usual path.

03

Build and validate

Deliver complete workflows in reviewable stages. Test representative records and failure paths with the people who will use the system.

04

Prepare the rollout

Reconcile migrated information, plan training and assign operational ownership. Track adoption and unresolved work after launch.

Questions about your project

Planning fintech software

Can you process financial messages into transaction records?

We can scope ingestion, parsing, categorisation and review around supported sources and representative examples. The BeeWise portfolio and finance SMS white paper describe this work in more detail.

Can a payment app confirm whether a payment succeeded?

That depends on the provider integration. We identify the authoritative status source during discovery and keep initiation, pending and confirmed states distinct in the user experience.

Can you work with an existing financial product?

Yes. Share the current data flow, provider integrations and user journeys so we can plan a defined improvement or integration alongside your existing application.

Start with your operation

Which workflow needs to work better?

Tell us who uses it, where work gets stuck and which systems need to connect. We’ll help shape a practical scope.
