What an Expense Tracking App Is
Struggling to keep your business spending in check? An expense tracking app is designed to simplify how startups and small businesses monitor and control their financial outgoings. At its core, a bubble expense tracking app lets founders and teams record, categorise, and analyse every transaction in one place, giving you a clear picture of your financial health. This clarity is vital for making fast, smart decisions in a competitive market.
Definition and Purpose
Expense tracking apps are digital tools that allow users to log, categorise, and review business or personal expenses. For startups, these apps are essential for maintaining control over spending and ensuring every pound is accounted for.
A bubble expense tracking app empowers non technical founders to automate financial tracking, reduce admin time, and maintain compliance. This supports better budgeting, forecasting, and overall business health.
Typical Use Cases
Expense tracking apps serve a wide range of practical needs:
- Managing personal and business expenses separately
- Streamlining team expense approvals and reimbursements
- Tracking transactions for tax and compliance purposes
For founders, the flexibility to adapt workflows and approval chains is key. A bubble expense tracking app makes it easy to tailor features as your business grows.
Key Benefits
The right expense tracking tool brings several advantages:
- Real time visibility over company cash flow
- Streamlined reporting to aid quick decision making
- Reduced manual errors through automation
With a bubble expense tracking app, you can monitor spending trends, set budgets, and identify savings opportunities, all from a central dashboard.
Current Trends in 2026
Modern expense tracking solutions are evolving rapidly. Key trends include AI powered categorisation, deeper banking and payment integrations, and a shift to mobile first interfaces. In fact, around 70% of SMBs now manage expenses via mobile devices.
For a detailed look at these emerging trends, including automation and AI, see Expense Management Trends 2026.
Advanced apps also offer seamless integration with accounting tools and real time notifications, making expense management smarter and faster.
Limitations of Manual Methods
Traditional methods like spreadsheets can be slow and error prone. Manual tracking increases the risk of data loss and inaccuracy, especially as transaction volumes grow.
A bubble expense tracking app eliminates these issues, giving you real time insights and reducing the need for tedious data entry. This shift from manual to automated processes is crucial for scaling startups who want to avoid costly mistakes.

Building a bubble expense tracking app lets you tailor everything from approval flows to branding, ensuring the solution truly fits your business requirements.
Core Features of an Expense Tracking App
A successful bubble expense tracking app relies on a core set of features that empower startups to manage finances with confidence. Below, we outline the must-have and advanced functionalities every founder should consider for their custom solution.
Essential Features
Every bubble expense tracking app should start with a solid foundation. Key capabilities include:
- Expense entry and categorisation: Users must be able to log expenses quickly, assign categories, and add details for each transaction.

Why Use Bubble.io for Expense Tracking Apps (and Its Limits)
Building a bubble expense tracking app is an attractive path for founders who want complete control without code. Bubble.io opens up the no-code world, letting you design, launch, and scale a tailored solution for your business needs.
What is Bubble.io?
Bubble.io is a no-code web application builder designed for people without traditional programming skills. Its drag-and-drop interface means you can create a bubble expense tracking app by visually assembling elements, workflows, and data types.
You do not need to write code to launch real, functioning apps. Bubble.io handles the complex backend logic, databases, and even hosting, so you can focus on solving business problems.
Advantages for Non-Technical Founders
One of the biggest strengths of Bubble.io is that it empowers non-technical founders to launch a bubble expense tracking app quickly. You can prototype ideas, test features, and iterate rapidly—ideal for startups that need to move fast.
This approach also reduces costs. Instead of hiring a developer or agency for every change, you can update features and design yourself. Bubble.io offers a range of templates and plugins, helping you get started with minimal upfront investment.
Scalability and Security

Security is a top priority. Bubble.io includes built-in protections like SSL, encrypted data storage, and privacy controls. For UK and EU startups, GDPR compliance features help you manage data responsibly and legally.
Integration Capabilities
A modern bubble expense tracking app needs to connect with other services. Bubble.io supports integrations with external APIs, allowing you to link your app to banking data, accounting platforms, or payment gateways.
Plugins extend functionality further. You can automate notifications, add AI-powered features, or enable OCR for receipts—without custom code. These integrations help create seamless, efficient workflows.
Limitations to Consider
While Bubble.io is powerful, it is important to understand its boundaries. Performance can slow with extremely large datasets, so for enterprise-scale needs, extra optimisation may be required.
Native mobile apps are not Bubble.io’s core strength, though responsive web apps work well on most devices. If your bubble expense tracking app requires advanced custom logic or niche integrations, you might need plugins or occasional code snippets.

Specialists can also speed up discovery, prototyping, and launch. They ensure your app is scalable, compliant, and future-proof, letting you focus on growth rather than technical hurdles.
How to Build an Expense Tracking App in Bubble.io: Step by Step Guide
Building a bubble expense tracking app as a non-technical founder is entirely possible with the right approach. This guide breaks down each phase, helping you go from idea to launch without writing a single line of code. Follow these steps to create a robust app tailored to your startup’s needs.
Step 1: Define Your Requirements
Start by clarifying the purpose and scope of your bubble expense tracking app. Identify all user roles your business will need, such as admin, employee, and accountant. Make a list of must-have features, like expense entry, approval workflows, and integration with accounting tools. Separate these from nice-to-have options, such as AI-powered categorisation or advanced analytics.
Next, sketch out the approval process. Decide how expenses will move from entry to approval and reimbursement. Map out how users will interact with each part of the app. Will employees submit receipts via mobile? Does an accountant need to review every transaction? Defining these workflows upfront will save you time and prevent costly changes later.
List any external integrations your bubble expense tracking app will require, like bank feeds or third-party accounting software. Ask stakeholders for input at this stage, ensuring all business requirements are covered. The clearer your requirements, the smoother the build process will be.
Step 2: Set Up Your Bubble.io Account and Project
Head to Bubble.io and sign up for an account. You can start with the free plan or choose a paid tier for additional features and scalability. Once registered, create a new app project. Bubble offers both blank projects and templates, so decide whether you want to build your bubble expense tracking app from scratch or adapt an existing design.
Give your app a meaningful name and select the appropriate project type. If you are new to no-code tools, consider starting with a template designed for expense tracking or financial workflows. This can accelerate your setup and reduce the learning curve. For a comprehensive overview of building MVPs with no-code platforms like Bubble, see the detailed Building an MVP with no-code guide.
Familiarise yourself with the Bubble editor. Explore the visual interface where you will design screens, workflows, and data connections. Review the documentation and tutorials offered by Bubble to get a sense of the platform’s capabilities. You are now ready to begin structuring your bubble expense tracking app.
Step 3: Plan Your Database Structure
Designing the right database structure is crucial for a successful bubble expense tracking app. Start by defining the main data types your app will use. Typically, you will need User, Expense, Category, and Receipt data types.
For each data type, list the necessary fields. For example, Expenses might include amount, date, description, status, and a link to the submitting user. Receipts should connect to their related expense and store an uploaded file or image. Categories help with filtering and reporting, so ensure these are flexible and easy to manage.
Plan relationships carefully. Each expense should be associated with a user, and receipts should link to expenses. Use Bubble’s visual database editor to create these types and fields. Test your structure with sample data to ensure it supports all your workflows.
Consider future scalability. If you anticipate large volumes of data, normalise your structure to avoid duplication and keep performance high. A well-designed database is the backbone of any reliable bubble expense tracking app.
Step 4: Design the User Interface
With your database in place, it is time to build the user interface for your bubble expense tracking app. Use Bubble’s drag-and-drop editor to lay out the key screens: a dashboard for real-time tracking, pages for expense entry, receipt upload, and reporting.
Break down each screen into user-friendly sections. The dashboard should show recent expenses, pending approvals, and budget status. Expense entry forms must be clear, with logical field ordering and helpful prompts. Receipt upload should allow drag-and-drop or mobile photo capture.
Prioritise mobile responsiveness throughout your design. Test layouts on different devices to ensure a seamless experience. Apply your company branding, including colours, logos, and fonts, to make the app feel professional and trustworthy.
Accessibility is important. Use clear labels and intuitive navigation, making it easy for all users to interact with your bubble expense tracking app. A polished interface builds confidence and adoption among your team.
Step 5: Build Core Workflows
Now, set up the logic that powers your bubble expense tracking app. Create workflows for submitting expenses, attaching receipts, and routing submissions for approval. Use Bubble’s visual workflow builder to define what happens when a user clicks “Submit” or “Approve”.
Add notifications to keep users informed. For example, email or in-app alerts can notify managers of pending approvals or remind employees to upload missing receipts. Automate repetitive tasks, like categorising expenses based on merchant or amount, using plugins or custom logic.
Test each workflow with different user roles. Ensure that permissions are respected, so employees cannot approve their own expenses and accountants can access all relevant data. Keep the process as simple as possible to avoid confusion.
Automation is a key advantage of using Bubble. By building robust workflows, your bubble expense tracking app will save time and reduce manual errors, making expense management far easier for your startup.
Step 6: Integrate External Services
To maximise value, connect your bubble expense tracking app with essential external services. Start by integrating with bank APIs to import transactions automatically. Bubble supports plugins and API connectors, making it possible to link with most banking and financial platforms.
Next, set up connections to accounting software like Xero or QuickBooks. This will streamline end-of-month processes and ensure your financial data is always up to date. Use Bubble’s plugin marketplace to find prebuilt integrations or create custom API connections if needed.
For receipt management, enable OCR (Optical Character Recognition) scanning using available plugins. This feature lets users upload photos of receipts, which are then automatically converted into expense records.
Test each integration in a sandbox environment before going live. Reliable integrations are essential for a seamless experience and for building trust in your bubble expense tracking app.
Step 7: Implement Security and Compliance Features
Security and compliance are non-negotiable for any bubble expense tracking app handling sensitive financial data. Start by enabling user authentication, requiring secure logins for all users. Use Bubble’s built-in permission controls to restrict access by role.
Activate SSL encryption for all data transmitted between users and your app. Store data securely in the Bubble database, and consider additional encryption for especially sensitive information.
If you operate in or serve the EU, implement GDPR compliance measures. Add consent forms at user signup and provide data export options. Make it easy for users to request data deletion if needed.
Regularly review your security settings and stay updated on Bubble’s compliance features. A secure bubble expense tracking app protects your business and reassures your users.
Step 8: Test and Iterate
Thorough testing is essential before launching your bubble expense tracking app. Begin by generating sample data and running through all workflows as different user roles. Check that expenses can be submitted, approved, and reported correctly.
Invite stakeholders or a small group of real users to try the app. Gather feedback on usability, performance, and features. Make note of any bugs, missing steps, or confusing elements.
Iterate quickly using Bubble’s visual editor. Adjust workflows, improve layouts, and refine notifications based on user input. Early and frequent testing helps you build a bubble expense tracking app that meets your team’s real-world needs.
Step 9: Launch and Maintain Your App
Once testing is complete, deploy your bubble expense tracking app to the live environment. Announce the launch to your team and provide training materials or walkthroughs to ensure a smooth rollout.
Monitor performance using Bubble’s built-in analytics tools. Track metrics like user activity, expense submission rates, and system errors. Plan regular updates to add new features, improve security, and address any issues that arise.
Establish a maintenance routine. Schedule backups, review security logs, and keep documentation up to date. Ongoing support ensures your bubble expense tracking app remains reliable as your business grows.

Common Mistakes When Building Expense Tracking Apps in Bubble.io
Building a bubble expense tracking app can be transformative for your startup, but certain pitfalls can derail your project. By understanding these common mistakes, you can save time, reduce frustration, and launch a more robust app.
Underestimating Data Structure Needs
Many founders dive into a bubble expense tracking app without carefully planning the database. Overlooking how expenses, categories, and users connect can result in slow performance and future headaches.
For example, failing to separate categories into their own data type can make reporting difficult and limit scalability. Always map out your data relationships before you start building.
Overcomplicating User Permissions
Adding too many roles or unclear permissions is a frequent trap. A bubble expense tracking app should keep access levels simple: typically admin, employee, and accountant.
Best practice is to use clear, role-based rules. Overly complex setups confuse users and increase bugs. Start with core permissions and expand only as needed.
Ignoring Mobile Usability
With most expense entries now made on the go, ignoring mobile design will frustrate users. A bubble expense tracking app built for desktop only can alienate your team and reduce adoption.
Ensure your app is fully responsive. Test all features on mobile devices and prioritise a clean, touch-friendly interface from the start.
Skipping Security and Compliance
Startups often rush to launch without robust security or GDPR features. In a bubble expense tracking app, neglecting encryption, secure logins, and consent management exposes you to risks.
Implement SSL, strong authentication, and data export options early. Compliance should be planned from day one, not retrofitted later.
Not Testing Integrations Thoroughly
Bank and accounting integrations are essential, but untested connections can break your app. Always use sandbox environments to check your bubble expense tracking app’s links to APIs.
Check data mapping, error handling, and transaction accuracy. Early testing prevents costly surprises after launch.
Delaying User Feedback
Waiting too long for real user input is a critical mistake. Early prototyping and stakeholder feedback help you spot missing steps, like overlooked approval flows.
Learn from other founders’ journeys by reviewing 10 successful startups built with Bubble to see how iterative feedback shaped their apps. Build, test, and refine in short cycles for best results.
Timeline and Cost Ranges for Building an Expense Tracking App in Bubble.io
Understanding the timeline and cost of building a bubble expense tracking app is vital for founders planning resources and setting realistic expectations. Each project is unique, but there are consistent patterns you can rely on. Here is what to expect from start to finish.
Typical Project Timelines
Most founders can launch a minimum viable bubble expense tracking app in about 2 to 4 weeks. This timeframe covers basic features such as expense input, receipt upload, and simple reporting.
For a full-featured solution with advanced integrations and automation, expect 4 to 8 weeks. This includes extra time for testing, feedback, and iterative improvements. Planning for these stages prevents rushed releases and ensures a stable launch.
Cost Estimates
The cost of a bubble expense tracking app will vary depending on your approach. If you choose the do-it-yourself route, costs are minimal, often just Bubble subscription fees and any paid plugins, typically £0 to £100 per month.
Hiring a professional agency or freelancer increases the investment. Expect to budget between £3,000 and £10,000 or more for a polished, scalable app. This price includes setup, design, and support.
Factors Affecting Cost and Time
Several elements influence your timeline and budget for a bubble expense tracking app:
- Feature complexity, such as multi-currency support or AI categorisation.
- Number of integrations with banks or accounting tools.
- Custom design versus using templates.
- Ongoing updates and maintenance requirements.
Understanding these factors upfront helps you avoid surprises and make informed decisions.
How to Optimise for Speed and Budget
To launch your bubble expense tracking app quickly and cost-effectively:
- Prioritise essential features for your MVP.
- Utilise pre-built templates and Bubble plugins where possible.
