Our Pick

Square edges ahead for most solopreneurs based on pricing and ease of use.

Overview

Square is a payment processing and invoicing platform designed to simplify financial transactions for solo entrepreneurs, freelancers, and small business owners. It offers an intuitive interface for creating invoices, accepting card payments both online and in-person, managing customer data, tracking inventory (for businesses selling physical goods), generating detailed reports on sales performance, and using its integrated POS system with features like loyalty programs and gift cards management. On the other hand, Trello is a project management platform that allows users to organize tasks visually through boards, lists, and cards. It’s ideal for freelancers managing multiple client projects or personal goals, offering flexibility in customizing workflows without extensive training. The core buying question for solopreneurs is whether they need a tool primarily focused on payment processing and invoicing (Square) or project management with visual task tracking (Trello).

Feature Comparison

Core use case Setup effort Collaboration Integrations Mobile/offline access Automation/API Export/lock-in Best solo workflow
Square Low Limited Multiple Partial Basic Some Invoicing, payment processing
Trello Low Moderate Many None Basic Minimal Project management, task tracking

Square and Trello serve different primary functions. Square is geared towards handling financial transactions efficiently with features like invoicing, payment processing, and inventory management. Its setup effort is minimal due to its straightforward interface, but it lacks extensive collaboration tools beyond basic customer management. While it offers partial mobile access and some automation capabilities, the export options are limited compared to Trello.

Trello focuses on project organization through visual boards, lists, and cards, making it easier for solo users to manage multiple projects visually without complex setup. It integrates well with other productivity apps like Evernote and Google Suite but lacks offline functionality. Both tools offer basic automation features, though Square’s API capabilities are more extensive due to its payment processing focus.

Pricing Comparison

Plan Type Square Free Square Plus ($49/mo) Square Premium ($149/mo) Trello Free Trello Standard ($5/user/month) Trello Premium ($10/user/month)
Solo Cost $0 $49 $149 $0 $5 $10

Square’s pricing tiers cater to varying business needs, starting with a free plan that includes basic invoicing and payment processing. The Plus Plan ($49/month) adds inventory management and customer profiles, while the Premium Plan ($149/month) offers comprehensive analytics and marketing support. Trello's free plan is sufficient for most solo projects but has limitations on storage and board numbers. Upgrading to the Standard Plan removes these limits at $5/user/month, with additional features in the Premium Plan.

For a solopreneur, Square’s pricing model can be safer due to its tiered approach that scales as business needs grow. The free plan offers essential invoicing and payment processing without monthly fees, making it ideal for startups or those on tight budgets. As your business expands, you can upgrade to the Plus Plan ($49/month) which includes inventory management—a crucial feature for businesses selling physical goods. Trello’s pricing is also straightforward but may become restrictive with its free plan limitations on storage and board numbers.

Square Strengths

  • Ease of Use: Square's intuitive interface allows solo users to set up payment processing and invoicing quickly, making it ideal for freelancers who need a simple solution without extensive training.
  • Integrated Solutions: With features like invoicing, payment processing, and POS systems all in one platform, solo entrepreneurs can manage their financial transactions efficiently from a single workspace.

Best For

Choose Square if:

  • You are a freelancer juggling multiple client projects who need a single workspace for invoicing and payment processing.
  • You are an indie hacker looking for an easy way to accept payments without setting up complex financial systems.
  • Your business involves selling physical goods that benefit from inventory tracking and management tools.

Choose Trello if:

  • You manage 3-5 client projects as a freelancer who needs a single workspace to manage tasks efficiently.
  • You are working on multiple side projects that benefit from visual organization.
  • You need a flexible tool for project management and task tracking without the complexity of enterprise solutions.

Verdict

For most solopreneurs, Square emerges as the better choice due to its comprehensive suite of payment processing and invoicing features. While Trello excels in visual project management, Square’s integrated solutions cater more directly to the financial needs of solo entrepreneurs. The tradeoff lies in whether you prioritize managing payments and invoices or organizing tasks visually.
