The quick answer

Use Stripe if you bill clients online, manage monthly IT retainers, offer subscriptions to your software tools, or need a flexible way to accept payments for custom development projects. Use Square if, by chance, you also sell physical tech products in person, though this is rare for most tech freelancers. Use PayPal when your international clients specifically ask for it, or for marketplaces like Upwork where it's already common.

Side-by-side breakdown

Stripe charges 2.9% + $0.30 per online transaction for most payments. It has no monthly fees, no contracts, and the most flexible tools for developers building custom checkout flows or integrating with client portals. It supports invoicing for project work, recurring subscriptions for SaaS or IT support, and connects with almost any website builder or accounting tool.

Square charges 2.6% + $0.10 for in-person transactions (if you ever need to swipe a card) and 2.9% + $0.30 for online payments. While it has online invoicing, Square's main strength is its hardware for retail stores. For freelance tech services, its online features are usually less robust than Stripe's and rarely needed.

PayPal charges 3.49% + $0.49 for standard online checkout. It is often more expensive than Stripe for most service-based transactions. However, it offers one big advantage: buyer trust. Many clients, especially international ones or those new to you, feel more comfortable paying via PayPal. It’s often used as a secondary option, not your main way to get paid.

When to choose Stripe

Choose Stripe for nearly any online-first tech service: web development projects, monthly IT support, AI prompt engineering services, custom software builds, or selling digital products. It handles recurring billing for your IT retainers or SaaS subscriptions better than any competitor. Stripe Invoicing is excellent for sending detailed bills to clients for project milestones. If you or a developer on your team will be customizing how clients pay on your website, Stripe's API is the industry standard. It's the go-to choice for modern freelance tech businesses that operate purely online.

When to choose Square

Choose Square only if you mainly accept payments in person, which is uncommon for most freelance tech and IT services. For example, if you ran a pop-up store selling physical components alongside IT consulting. The free card reader and simple POS app are great for retail. However, for online invoicing or managing subscriptions for your IT clients, Stripe or PayPal are far better fits. For most solo developers, web designers, or IT support, Square's primary benefits won't apply.

When to choose PayPal

Choose PayPal as a secondary payment option for specific scenarios. This includes when your client base is international, uses platforms like Upwork where PayPal is common, or when clients are new and cautious about entering card details on an unfamiliar site. Many freelancers who bill clients globally use PayPal because it handles currency conversion easily and is trusted worldwide. However, do not use PayPal as your only payment option – its fees are higher, and its checkout process can sometimes lead to fewer completed payments than Stripe for professional services.

The verdict

For solo developers, IT consultants, web designers, and AI prompt engineers: Stripe is the clear winner for online services, invoicing, and recurring payments. Add PayPal as a backup option if your clients often request it or if you deal with many international payments. Square is almost never the right primary choice for online tech freelancers. The default for most tech founders starting out is Stripe – set it up in 30 minutes and focus on building your client base and delivering great service.

How to get started with Stripe

Setting up Stripe is straightforward: create an account, verify your identity and business details (even if you're a sole proprietor), connect your bank account, and enable the tools you need. For quick one-off payments like a deposit for a web project or a single consultation fee, use Stripe Payment Links. For ongoing IT support or software subscriptions, use Stripe Billing. For detailed project work, use Stripe Invoicing. Create your first Payment Link in five minutes and send it to your first prospect. Payment Links feel more professional and ensure immediate payment, rather than waiting for bank transfers or checks.

FREQUENTLY ASKED QUESTIONS

Can I use Stripe if I am a sole proprietor without a business entity?

Yes. Stripe accepts sole proprietors and individuals. You will need your SSN for identity verification and a bank account in your name. You do not need an LLC or EIN to start.

How long does it take for Stripe payouts to reach my bank?

Standard is two business days. Stripe Instant Payouts are available for an additional 1.5% fee if you need same-day access. Most founders use standard payouts and schedule their cash flow expectations around the two-day window.
