Managing invoicing efficiently is critical for today’s CEOs, freelancers, and business owners alike. Time saved on billing is time reinvested in growth. With the rise of streamlined fintech tools, choosing the right invoicing software has never been more important. Among the options available, two frequently stand out: Invoice Simple and Invoice Fly. While both offer a suite of features designed to simplify invoicing tasks, there are clear differences that make one the stronger choice for high-performing business leaders.
In this article, we compare both platforms across key areas—features, pricing, user experience, scalability, and integrations—ultimately showing why Invoice Fly is the smarter, more strategic option.
1. The Role of Smart Invoicing in Leadership Efficiency
Before diving into the comparison, it's essential to understand why invoicing software matters at the executive level.
Manual invoicing eats up valuable hours and introduces avoidable errors. According to Forbes, businesses that automate their invoicing reduce billing errors by over 60% and get paid 25% faster on average. CEOs juggling client work, investor relations, and internal operations simply cannot afford to let billing become a bottleneck.
Enter digital invoicing platforms—solutions built for speed, accuracy, and brand professionalism.

Key Features:
- One-click invoice creation

3. Invoice Simple Overview: A Basic but Popular Tool
Invoice Simple is another tool targeting freelancers and small businesses. It has been around for several years and gained popularity for its straightforward design and basic invoice templates.
Features include:
- Mobile and web access
- Simple invoice and estimate creation
- Accepting payments through Stripe or PayPal
- Basic reporting tools

While it meets the basic needs of many independent workers, its simplicity becomes a limitation for users who want more robust tracking, customization, or scalability options.
4. User Experience & Interface

Invoice Fly: Sleek and Intuitive
Invoice Fly’s mobile-first design offers a clean and modern user interface. Whether accessed through Android, iOS, or desktop, its dashboard is clear and organized, allowing even non-tech-savvy users to generate, edit, and send invoices on the go.
The customization is also seamless—you can upload your logo, choose your brand colors, and personalize messages with just a few taps.
Invoice Simple: Functional but Dated
Invoice Simple provides a basic interface. While it's easy to use, it lacks the visual sophistication and flexibility that Invoice Fly offers. Customization is more limited, and the design choices can feel outdated compared to modern invoicing tools.
5. Customization & Branding
Your invoice is often the last point of contact with a client—and it says a lot about your brand.
Invoice Fly allows advanced customization:
- Upload logo
- Add color accents
- Insert custom footer messages
- Choose from different template styles
These touches help reinforce your brand identity.
In contrast, Invoice Simple offers fewer customization options and minimal control over template appearance. You can include your logo and change some field labels, but overall, it’s more template-restrictive.
6. Mobile Functionality
Both platforms offer mobile apps, but here’s where Invoice Fly takes the lead.
- Invoice Fly: Designed mobile-first; includes all desktop features and a fast, touch-optimized UI.
- Invoice Simple: Mobile app is functional, but some advanced features are reserved for desktop users.
For today’s CEO who needs to send invoices while commuting, attending meetings, or managing remote teams, Invoice Fly provides a smoother and faster experience.
7. Pricing & Value
Invoice Fly
- Offers a generous free plan
- Premium version is affordable and offers unlimited invoices
- No hidden fees or confusing pricing tiers
Invoice Simple
- No functional free plan (only a trial)
- Requires monthly or annual subscriptions for basic features
- Slightly higher price point compared to Invoice Fly for fewer features
In terms of ROI, Invoice Fly offers more functionality for less cost, especially for startups and solopreneurs.
8. Integrations and Ecosystem
While neither app matches the integrations offered by enterprise-level platforms like QuickBooks, Invoice Fly is beginning to support syncing with other tools (e.g., accounting software, tax calculators, CRM systems).
Invoice Simple has a relatively closed ecosystem with limited integrations, especially in the lower-tier plans. This makes it harder to scale or link billing with other operational workflows.
9. Payment Flexibility

Accepting digital payments is a must.
- Invoice Fly supports multiple payment methods and allows users to include bank details, QR codes, and links for digital wallets.
- Invoice Simple offers PayPal and Stripe integrations but lacks wider flexibility or dynamic payment tracking.
Invoice Fly also includes due date tracking, reminders, and “paid” status labels to improve collection rates.
10. Invoicing in Multiple Currencies & Languages
If you're a global entrepreneur, this feature is a dealbreaker.
- Invoice Fly supports multiple currencies and languages—ideal for international clients.
- Invoice Simple supports only limited international settings and lacks full language localization.
This makes Invoice Fly a far better choice for CEOs with cross-border operations or remote teams.
11. Customer Support & User Feedback
Invoice Fly:
- Email and in-app support
- Active community feedback used for ongoing updates
- Excellent response times reported by users
Invoice Simple:
- Email-only support
- Mixed reviews regarding response times and billing issues
Invoice Fly’s support experience feels more agile and personalized, reflecting the needs of modern mobile-first users.
12. Security and Data Management
Security is non-negotiable for CEOs.
- Invoice Fly stores all data on secure cloud infrastructure and ensures encryption in transit and at rest.
- Invoice Simple also uses secure protocols, but the specifics of data retention and backup options are not as transparent.
Invoice Fly’s regular backups and clear data ownership terms provide peace of mind for growing businesses.
13. Best Use Cases
Invoice Fly is Ideal For:
- Entrepreneurs and startup CEOs
- Consultants and creative freelancers
- Business owners billing international clients
- Leaders needing rapid, branded invoicing on mobile
Invoice Simple is Suitable For:
- Independent contractors with basic invoicing needs
- Users comfortable with minimal customization
- Sole proprietors with U.S.-only clients
For CEOs and growing companies, Invoice Fly clearly scales better and offers more powerful capabilities.
14. Final Verdict: Invoice Fly Wins
Both platforms aim to simplify billing—but Invoice Fly emerges as the winner for serious professionals who demand speed, flexibility, and global readiness. Its beautiful UI, superior customization, lower pricing, and international features make it the top recommendation for CEOs and modern entrepreneurs.
While Invoice Simple may satisfy basic invoicing needs, its limitations in branding, currency support, and integration make it a less viable choice for today’s fast-paced business environment.
