As developers, we often build projects to learn a new framework or library.
This time, I wanted to solve a real-world business problem while exploring modern frontend architecture.
The result is Quick Quotations, a quotation management application built with Next.js, TypeScript, and IndexedDB that allows businesses and freelancers to create professional quotations without relying on a backend.
The entire application runs inside the browser.
Why I Built It
Many small businesses still create quotations using Word documents, spreadsheets, or PDFs that need to be edited manually.
That approach has several problems:
- Repetitive work
- Inconsistent formatting
- Difficult editing
- Manual calculations
- No centralized quotation history
I wanted a solution that was:
- 1. Fast
- 2. Modern
- 3. Offline-friendly
- 4. Easy to use
- 5. Privacy-focused
Instead of storing user data on a server, I decided to store everything locally using IndexedDB.
This means users keep full control over their own data while enjoying an application-like experience.
Tech Stack
The application is built using:
- Next.js (App Router)
- React
- TypeScript
- Tailwind CSS
- React PDF
- IndexedDB
Each technology was chosen for a specific reason.
Next.js App Router
The App Router makes organizing large applications much easier through layouts, nested routing, and server/client component separation.
TypeScript
Type safety becomes increasingly valuable as applications grow.
It helped catch bugs early and made refactoring much safer.
React PDF
Generating professional PDFs inside React was one of the most interesting parts of this project.
The exported PDF closely matches the live preview shown inside the application.
IndexedDB
Instead of building an authentication system and backend API, I wanted the application to remain completely client-side.
*IndexedDB provides:
*
- Large storage capacity
- Structured data
- Fast queries
- Offline support
Users can continue working without an internet connection.
*Tailwind CSS
*
Tailwind made it easy to build reusable UI components while maintaining a consistent design system.
Features
- Create Quotations
- Create professional quotations in minutes.
- No complicated forms.
- No unnecessary steps.
- Edit Existing Quotations
- Every quotation remains editable after creation.
- Update customer information, products, taxes, discounts, or notes whenever needed.
Live PDF Preview
One feature I particularly enjoyed building was the live preview.
Users immediately see how their quotation will look before exporting it. There are no surprises after generating the PDF.
Professional PDF Export quotations as polished PDFs suitable for clients.
The layout is designed to look clean, consistent, and business-ready.
Company Profile Management
Store company information once and reuse it across every quotation.
This includes:
- Company name
- Address
- Country
- State
- Contact information
- Tax details
- Automatic Calculations
The application automatically calculates:
- Subtotal
- Discounts
- Taxes
Grand Total
This reduces manual errors.
Local Data Storage
Every quotation is stored inside IndexedDB.
No backend.
No database server.
No account required.
Responsive UI
The interface works smoothly across desktop and laptop screens while maintaining a clean, modern design.
Challenges I Faced
Every project teaches something new.
This one was no exception.
1. PDF Generation
Creating responsive web pages is one thing.
Generating identical PDF layouts is another.
React PDF follows different rendering rules compared to HTML and CSS, so several layouts had to be redesigned specifically for PDF generation.
2. Synchronizing Preview and PDF
Keeping the live preview visually identical to the exported PDF required careful component organization.
The goal was simple:
What users see should be exactly what they export.
3. Client-Side Architecture
Without a backend, data management becomes even more important.
Designing reusable services around IndexedDB helped keep the application organized and scalable.
- Reusable Components
Instead of writing separate UI for every page, I focused on reusable components that could be shared throughout the application.
This reduced duplication and simplified future development.
What I Learned Building this project improved my understanding of:
Next.js App Router
TypeScript architecture
Client-side databases
PDF generation with React
IndexedDB data modeling
Component reusability
Form management
Business application workflows
Modern frontend architecture
Future Improvements
The current version focuses on local-first usage, but there are many features I'd like to explore in the future.
Some ideas include:
- Customer management
- Product catalog
- Multi-currency support
- Quotation templates
- Dark mode
- Import and export backups
- Cloud synchronization (optional)
- Analytics dashboard
- Email quotation directly from the app
- Multi-language support
- Why Local-First?
One design decision I'm particularly happy with is choosing a local-first architecture.
Not every application needs a backend.
For many small business tools, storing data locally provides several advantages:
- Better privacy
- Faster performance
- Lower hosting costs
- Offline capability
- Simpler deployment
Sometimes the simplest architecture is the best architecture.
Final Thoughts
Quick Quotation
s started as a learning project, but it evolved into something that solves a genuine business need.
It gave me practical experience with Next.js, IndexedDB, React PDF, and scalable frontend architecture while reinforcing the importance of building applications around real user problems.
There are still many features I'd like to add, but I'm proud of how far the project has come.
If you're building business tools with Next.js or experimenting with local-first applications, I'd love to hear your thoughts and learn how you approach similar challenges.
Happy coding! 🚀
