Full-featured accounting at a lower price point. Invoicing, expense tracking, project billing, inventory, and payroll. Free plan available for businesses under $50K revenue. Integrates with the broader Zoho suite.
Never mix personal and business finances. Mercury is the best option for startups and online businesses — no fees, no minimums, FDIC insured, and integrates with everything. Open it the same day you register your business. It takes 10 minutes online.
Stripe is the default for online businesses, SaaS, and marketplaces. It handles subscriptions, one-time payments, invoicing, and international transactions with one integration. For in-person payments, add Square. Don't use PayPal as your primary processor — fees add up and account freezes are common.
For the first year, Wave (free) or Zoho Books (free under $50K revenue) handle most invoicing and expense tracking needs. When you hire employees, add payroll with Gusto. When your books get complex or you need an accountant, upgrade to QuickBooks or Xero — they have the widest accountant support.
When you have employees spending company money, manual expense reporting is a productivity killer. Ramp provides corporate cards with automatic receipt capture and real-time spend controls — it's free for the base plan and pays for itself in reduced spend. For very small teams, a shared business credit card with QuickBooks auto-import is sufficient.
Software doesn't replace strategic financial advice. Once your revenue is meaningful, a good accountant more than pays for themselves in tax optimization. Make sure your accounting software (QuickBooks or Xero) is accountant-accessible with proper user permissions before that conversation.

QuickBooks Online is the most widely used small business accounting software in the US, starting at $35/month. Xero is a strong alternative with better international support at similar pricing. FreshBooks is the best option for freelancers and service businesses at $19/month. Wave and Zoho Books both offer free plans for very early-stage businesses.
Stripe is the best payment processor for online businesses and startups, charging 2.9% + 30¢ per transaction with no monthly fee. Square is better for brick-and-mortar businesses with in-person payments. PayPal is good for international transactions and consumer trust, but has higher fees and account stability issues. For high-volume businesses, negotiated rates with Stripe can reduce fees significantly.
Yes — mixing personal and business finances creates serious legal and tax complications. If your business is structured as an LLC or corporation, co-mingling funds can void your liability protection ("piercing the corporate veil"). Mercury is the best online business bank account for startups — no fees, no minimums, and FDIC insured up to $5M through partner banks.
QuickBooks is better for US-based businesses with complex inventory and payroll needs — it has the largest accountant network in the US, so your CPA almost certainly knows it. Xero is better for international businesses, multi-currency transactions, and has a cleaner modern interface. Both cost roughly the same. If you're in the US, start with QuickBooks. If you're outside the US, Xero is likely the better choice.
Use a dedicated business credit card with expense management software. Ramp provides corporate cards with automatic receipt capture, spend controls, and 1.5% cashback — the base plan is free. For very small teams, a shared business credit card with bank feed integration into QuickBooks or Xero is sufficient. Never pay for expenses on a personal card and try to reimburse yourself — it creates accounting chaos.
