Outsourced accounting has grown well beyond basic bookkeeping. Today, businesses can choose from providers that combine technology with bookkeeping, tax, payroll, and fractional CFO support.

But not every provider is built for the same type of business. Some focus on startups, others lean heavily on automation, and some offer a broader range of accounting services.

Below, we compare five leading providers, including their strengths, limitations, and best use cases, and explain why Bookkeeper360 is our pick for the best overall option for growing small and midsize businesses.

See how Bookkeeper360 can support your bookkeeping, tax, payroll, and CFO needs.

1. Bookkeeper360: Best Overall for Growing Small and Midsize Businesses

Bookkeeper360 combines bookkeeping, tax preparation and planning, payroll administration, sales tax, back-office support, and fractional CFO services under one team, helping businesses avoid stitching together multiple providers as they grow.

Strengths

• Bookkeeping, tax, payroll, sales tax, and fractional CFO services available through one provider

• Dedicated U.S.-based accounting professionals
• Monthly and weekly bookkeeping options
• Services can be added individually as business needs evolve
• Bookkeeper360 technology provides financial dashboards, business metrics, and greater visibility into financial performance

Why use Bookkeeper360?

Flexible engagement: Businesses can add services based on what they need rather than changing accounting providers every time a new financial need arises.

Room to grow: A company can start with bookkeeping and add payroll, tax planning, or fractional CFO support as its needs become more complex.

Weekly bookkeeping option: Businesses that need more frequent visibility can choose weekly bookkeeping rather than relying only on a monthly close.

Best for: Growing small and midsize businesses that want a long-term accounting partner with human expertise, technology, and the flexibility to expand support as their needs evolve.

2. Xendoo

Xendoo is a tech-forward online bookkeeping firm with tiered monthly plans, weekly bookkeeping, and a financial dashboard included on every plan.

Strengths

• Weekly bookkeeping and the Insights XP financial dashboard included on every plan, with no onboarding or setup fees
• Tiered plans (Essential, Growth, Scale) scale from cash basis to full accrual as expense volume and account needs grow
• Two-time Xero National Partner of the Year, with a dedicated Q2X specialist for QuickBooks-to-Xero migrations
• Catch-up bookkeeping and a fractional CFO add-on available for businesses that need more than core bookkeeping
• In-app chat with your accountant plus monthly check-in calls to review financials

Limitations

• Tax filing is a separate add-on rather than bundled into the base monthly plan.
• The entry-level plan is cash-basis only, with accrual available on higher tiers.
• Pricing scales with monthly expense volume, so costs rise as a business grows, with add-ons for tax, catch-up work, or CFO support.

Best for: Small businesses on QuickBooks Online or Xero that want weekly bookkeeping with tiered plans that scale by expense volume, and are comfortable purchasing tax services separately.

3. Uplinq

Uplinq combines AI-powered bookkeeping automation with accountant oversight, creating a technology-forward approach to bookkeeping and tax support.

Strengths

• AI-assisted bookkeeping and reconciliation
• Accountant oversight
• Business tax compliance and strategy services
• Catch-up bookkeeping available
• Lower entry point than some startup-focused finance providers

Limitations

• Services are priced in separate modules, so total costs can increase as additional support is added.
• Payroll and sales tax are not central parts of its core offering.
• Its service model is more technology-led than a traditional full-service outsourced accounting relationship.

Best for: Small businesses, solo entrepreneurs, and self-employed professionals that want technology-driven bookkeeping and tax support.

4. 1-800Accountant

1-800Accountant is a large virtual accounting provider that combines dedicated accountant support with bookkeeping, tax preparation, tax advisory, and payroll services.

Strengths

• Broad tax and bookkeeping offering
• Dedicated accountant included with plans
• Payroll support available
• Large national presence serving small businesses across the U.S.

Limitations

• Bookkeeping is bundled into higher-tier plans rather than being the focus of its lower-priced offerings.
• Its packages are structured heavily around tax advisory and tax preparation.
• Businesses looking for more frequent financial reporting or a highly customized accounting and CFO relationship may find the standardized package structure limiting.

Best for: Small businesses primarily looking for packaged tax, bookkeeping, and accounting support.

5. Bench

Bench is an online bookkeeping and tax service that pairs proprietary software with dedicated bookkeeping experts. After its 2024 shutdown and relaunch, Bench now operates as part of Mainstreet.

Strengths

• Dedicated bookkeeping experts
• Monthly bookkeeping and year-end tax-ready financial packages
• Income tax filing and year-round tax advisory available
• Proprietary platform with financial reporting and account integrations
• Catch-up bookkeeping and QuickBooks Online bookkeeping support available

Limitations

• Its standard bookkeeping plans use Bench’s proprietary platform rather than keeping the books directly in QuickBooks Online or Xero.
• Its core service lineup is centered on bookkeeping and income tax rather than a broader outsourced accounting suite that includes payroll, sales tax, and fractional CFO support.
• Bookkeeping is primarily monthly, which may be less frequent than businesses looking for weekly close support.
• Bench went through a shutdown and insolvency in late 2024 before being acquired and relaunched, which businesses may want to consider when evaluating provider history and continuity.

Best for: Small businesses that want monthly bookkeeping and income tax support through a dedicated team and a proprietary software platform.

How to Choose the Best Online Accounting Partner

• How often do you need your books updated? A stable business may be fine with a monthly close, while a fast-growing company may need weekly or more frequent visibility into cash flow and expenses.
• Do you only need bookkeeping, or will you eventually need tax, payroll, sales tax, or CFO support too? Choosing a provider that can grow with you can reduce the need to manage multiple disconnected vendors later.
• How predictable is the pricing? Some providers use standardized monthly pricing, while others price services separately or increase costs as complexity grows.
• Do you get access to a real person who knows your business? Consider whether you will work with a dedicated professional or whether support is routed through a broader service team.
• Does the provider fit your type of business? Some are built for straightforward bookkeeping and tax, while others support broader needs such as payroll, sales tax, and CFO advisory.
• Can you keep your existing accounting platform? Businesses already using QuickBooks Online or Xero should consider whether switching systems will be required.
