QuickBooks vs FreshBooks vs Wave vs Xero: Best Accounting Software for Private Practice & MedSpa Startups

The Quick Answer

Wave works best for new solo nurse practitioners, physical therapists, or functional medicine doctors who need free, basic bookkeeping before they have many patients. FreshBooks is great if your practice mainly bills patients for appointments or services directly, like cosmetic injections or physical therapy sessions. QuickBooks Online is the safest bet if you plan to hire a medical billing specialist, a CPA, or expand your team — most professionals already know it. Xero is best if your MedSpa or functional medicine practice sells a lot of physical products like supplements, skincare, or medical devices.

Side-by-Side Breakdown

Wave: Wave is free for managing your practice's books and sending patient invoices. It charges 2.9% + 30c for each credit card payment, which is standard for patient payments. It doesn't track inventory for supplements or products. Reports are basic. Best for: Solo practitioners like new NPs or PTs with low patient volume and no product sales.

FreshBooks: FreshBooks starts at $19/month (Lite plan). It has excellent tools for sending patient invoices, tracking time spent per patient visit or procedure, and a portal where patients can view bills. Its core accounting might not be as deep for complex medical finances. Best for: Practices focused on direct patient services and billing, such as aesthetic nurses or physical therapists who bill hourly or per session.

QuickBooks Online: QuickBooks Online starts at $35/month (Simple Start). It offers the most complete set of features, including payroll for your clinic staff, and connects with over 750 other tools, like some EMRs or practice management software. It has strong reporting for understanding your practice's financial health. It can be harder to learn at first. Best for: Practices planning to grow, hire front desk staff, add other practitioners, or needing robust reports for clinic expansion.

Xero: Xero starts at $15/month (Early plan, limited). All plans allow unlimited team members to access the accounting system, which is good if you have a medical assistant or billing specialist. It has strong tools for managing your inventory of medical supplies, supplements, or skincare products and creating purchase orders for reordering. It has a great mobile app. Best for: MedSpas or functional medicine clinics that sell many products, or practices with multiple staff members needing accounting access.

When to Choose Wave

Choose Wave if you are a new solo practitioner just starting your private practice, perhaps seeing your first few patients or grossing under $10,000 per month. Your practice income comes from simple patient fees, with no sales of supplements or medical products. You don't have employees yet and won't deal with foreign currency for medical tourism. You need easy, clean bookkeeping without paying a monthly fee. Wave is also a good temporary solution while you test your practice model before investing in a more complex system.

When to Choose FreshBooks

Pick FreshBooks if your practice bills patients primarily based on appointments, hourly rates for therapy, or fixed service packages (like a set of aesthetic treatments). You send many invoices directly to patients and want them to pay quickly and easily online. You track how much time you spend with each patient or on specific procedures. You don't need highly detailed accounting for complex financial statements; a CPA familiar with medical practices can still use FreshBooks but might need to do extra work to prepare advanced reports.

When to Choose QuickBooks Online

Select QuickBooks Online if you plan to hire a medical biller, practice manager, bookkeeper, or CPA for your clinic within the next year — almost all of them are familiar with QuickBooks. You need to run payroll for your medical assistants, front office staff, or other practitioners without using a separate system. Your MedSpa or functional medicine practice sells both direct services (like IV therapy or consultations) and physical products (like medical-grade skincare or supplements) and you need detailed reports for both. You're preparing for a practice expansion, seeking a bank loan for new equipment like a laser, or looking for investors, and need highly accurate, audit-ready financial statements.

When to Choose Xero

Choose Xero if your MedSpa or functional medicine practice manages a lot of physical inventory, such as high-cost injectables, specific supplements, or skincare lines, and you need to track stock levels and reorder using purchase orders. If you treat international patients and bill in multiple currencies, Xero handles this well. If your clinic has more than two staff members who need access to the accounting system (e.g., practice manager, billing specialist, owner), Xero's unlimited user feature is a big cost saver as your team grows. While very popular overseas, its US bank integrations are still strong for private practices.

The Verdict

For most new US-based private healthcare and MedSpa practices aiming for $0 to $500,000 in early revenue: begin with Wave. Upgrade to QuickBooks Online once you hire your first medical biller, practice manager, or start running payroll for staff. If your practice primarily offers services and bills patients directly for appointments or procedures, go straight to FreshBooks. If your MedSpa or functional medicine clinic sells a significant amount of physical inventory like supplements or products from day one, start with Xero.

How to Get Started

Wave: Create your free account at waveapps.com. Link your practice's business bank account and credit card accounts. Then, go back and categorize the last 30 days of transactions, labeling patient payments, medical supply purchases, and rent to get a clear starting point.

FreshBooks: Start the 30-day free trial. Design a professional invoice template for your patient billing. Input your first few patient profiles and their typical service codes before the trial period ends, so you have actual practice data to see how it works.

QuickBooks Online: Use the 30-day free trial. If you've already chosen a CPA or medical billing specialist, ask them which QuickBooks plan best suits your private practice and future growth plans; they often have access to partner discounts.

Xero: The Xero Early plan ($15/month) limits you to 20 patient invoices per month, which might be too few for a busy clinic. Most growing MedSpas or private practices will need the Growing plan ($42/month) within 90 days. Factor this cost into your budget from the start.
