Top 8 Accounting Services in Arizona for Small Businesses

This list of top accounting firms spans virtual-first platforms, local Arizona firms, and self-service tools, so whether you're a solo freelancer in Tempe or a growing operation in Phoenix, you'll find a great fit for your situation.

1. 1-800Accountant (best overall for Arizona small businesses)

For Arizona business owners who want a full-service accounting team without the overhead of a traditional firm, a virtual model with flat-rate pricing is hard to beat. 1-800Accountant serves small businesses, freelancers, and self-employed professionals across Arizona and every other state through a secure online platform, pairing you with a dedicated accountant experienced in the tax nuances of your industry.

Core services include full-service bookkeeping, tax preparation, tax advisory, payroll, and entity formation. The flat-rate pricing structure removes the uncertainty associated with hourly billing by local firms. You know exactly what you're paying each month, which makes budgeting easier.

What sets 1-800Accountant apart from many options is its year-round tax advisory support. You're not just getting someone to file your return in April; you're getting ongoing guidance that helps you make smarter decisions throughout the year, including managing Arizona's transaction privilege tax obligations.

• Pros: Fully virtual and accessible statewide; flat-rate, predictable pricing; covers everything from bookkeeping to payroll; year-round tax advisory, not just seasonal filing

• Cons: No in-person meetings; may be more than a pre-revenue business needs right away

• Best For: Solo operators, freelancers, and small business owners who want ongoing professional support without the cost of a traditional local firm

2. Bench Accounting

Bench is a tech-forward bookkeeping service that pairs intuitive software with human bookkeepers, giving you clean monthly financials without having to manage the process yourself. It's a popular choice for business owners who want organized books but aren't looking for full-service tax advisory or payroll support.

After experiencing a significant service disruption in 2024, Bench was acquired.

• Pros: User-friendly dashboard; dedicated bookkeeper; integrates with common accounting tools; tax prep and advisory services have been added

• Cons: Newer services lack the depth of the main bookkeeping offering; recent ownership changes create some uncertainty about long-term service consistency

• Best For: Small businesses that need clean books from a reliable provider

3. Pilot

Pilot is a virtual accounting firm built primarily for startups and venture-backed companies. It offers bookkeeping, tax, and CFO-level services through a dedicated finance team, with strong software integrations suited to tech-forward operations.

The pricing reflects its startup-focused positioning, which means it falls into a higher-cost tier than most small business options. If you're running a typical Arizona small business, a retail shop, a service business, or a solo practice, Pilot may offer more than you need at a price point that doesn't match your stage.

• Pros: Deep startup expertise; dedicated finance team; strong integrations with tools like QuickBooks and Stripe

• Cons: Pricing is not well-suited for very small businesses; less relevant for non-tech industries

• Best For: Early-stage startups in Tempe, Scottsdale, or the Phoenix tech corridor with investor reporting needs and growth-stage accounting requirements

4. inDinero

inDinero is an all-in-one accounting platform covering bookkeeping, tax, payroll solutions, and CFO advisory services. It targets growing small businesses and mid-market companies, combining software with human accountants to give you a single point of contact for most financial needs.

Pricing is tiered and scales with complexity, which means costs can rise quickly as your business grows. It occupies a similar space to other full-service virtual firms but tends to position itself at a higher price point.

• Pros: Full-service offering under one roof; good fit for scaling businesses; combines software tools with human support

• Cons: Higher cost relative to alternatives; may be excessive for very small or early-stage businesses

• Best For: Growing Arizona businesses that need integrated bookkeeping, tax, and advisory and are ready to invest in a more comprehensive solution

5. Paro

Paro operates as a marketplace that matches businesses with freelance finance professionals, including bookkeepers, accountants, and fractional CFOs. Rather than assigning you to a fixed team, Paro vets its network and pairs you with a specialist based on your specific needs.

If you're considering outsourcing accounting but aren't sure you need a full-time engagement, Paro's flexible model may make sense. The tradeoff is consistency: your experience depends heavily on which professional you're matched with, and pricing is less predictable than flat-rate services.

• Pros: Flexible project-based or ongoing engagements; access to specialized talent; fractional CFO option available

• Cons: Variable quality depending on the matched professional; less predictable pricing than subscription-based services

• Best For: Arizona businesses that need project-based or fractional finance support rather than ongoing full-service accounting

6. DIY Accounting Software (QuickBooks, Wave, or FreshBooks)

Some Arizona small business owners, particularly those just starting out, save money by managing their own books using software. QuickBooks is the most feature-rich option and works well for businesses with employees or inventory. Wave is free for basic bookkeeping and suits very simple operations. FreshBooks is a strong choice for freelancers and service-based businesses that primarily need invoicing and expense tracking.

DIY works when your finances aren't particularly complex. As your business grows, concerns and risks multiply. Estimated tax calculations, tracking deductible expenses, and Arizona-specific obligations such as the transaction privilege tax can create real compliance problems without tailored solutions and professional guidance. The IRS maintains a list of acceptance agents in Arizona for certain tax matters, which gives you a sense of the state's compliance infrastructure and why professional support often pays for itself.

• Pros: Low-cost investment; owner maintains direct visibility into day-to-day finances

• Cons: Time-intensive to manage correctly; error-prone without accounting knowledge; no tax advisory or planning support

• Best For: Highly recommended for pre-revenue businesses or very early-stage sole proprietors with simple finances and the time to manage their own records carefully

7. Wallace Plese + Dreher

Wallace Plese + Dreher is one of the most recognized Arizona accounting firms, ranked number one in the state by Ranking Arizona for several years and recognized by Accounting Today as a Southwest Regional Leader. The organization offers a full range of services, including tax, audit, review, business consulting, and business advisory services.

Their professionalism and expertise are a strength for businesses that need audit support or complex multi-entity tax work. That same depth comes at a cost and with a professional service model that's better suited to established businesses than to startups or solo operators.

• Pros: Strong local reputation with consistent regional recognition; full-service, including audit capabilities and tax strategies; deep Arizona market knowledge

• Cons: Higher cost than virtual alternatives; better suited for established businesses than early-stage or very small operations

• Best For: Established Arizona businesses with complex tax or audit needs that benefit from in-person, locally rooted expertise

8. Lohman Company

Lohman Company is a Mesa-based firm that has been serving clients throughout Arizona and beyond since the turn of the century. Their focus spans tax and accounting for both businesses and individuals, and they handle clients with multi-state and international needs in a timely fashion.

For Arizona business owners with operations or income sources across multiple states, or those with cross-border considerations, Lohman's experience in that space is a practical differentiator. This Arizona small business tax guide is a useful starting point for understanding the state-specific obligations that any firm you hire should be prepared to address.

• Pros: Long operating history with established client relationships; handles multi-state and international tax needs; serves both business and individual tax clients

• Cons: Local firm pricing model may not suit very small budgets; in-person focus limits accessibility for remote or statewide clients

• Best For: Arizona-based businesses with multi-state operations, international considerations, or owners who prefer working with a long-tenured local firm

Why 1-800Accountant Stands Out for Arizona Small Businesses

Arizona's small business landscape is diverse, and most owners don't need a large local firm or an enterprise-grade platform to prosper. They need reliable, affordable support that covers the full picture: bookkeeping, taxes, payroll, and tax planning, without the unpredictability of hourly billing or the limitations of DIY software.

That's exactly where 1-800Accountant's suite of professional accounting solutions shines. Here's what makes it a strong choice for Arizona business owners:

• Dedicated accountant: You're matched with a professional who gets to know your business, not a different person every time you call.

• Flat-rate, transparent pricing: No hourly surprises. You know your costs upfront, which makes financial planning easier.

• Full-service coverage: Bookkeeping, tax preparation, tax advisory, payroll, and entity formation are all available under one roof.

• Year-round support: Tax guidance doesn't stop after April 15th. You get ongoing advisory help for decisions that affect your tax position throughout the year and in the long term.

• Accessible from anywhere in Arizona: Whether you're in Phoenix, Tucson, Flagstaff, or a smaller market, the fully virtual model means you're never limited by geography.

• Built for small businesses: The entire service model is designed around owners like you, not corporate clients with dedicated finance departments.

Frequently Asked Questions

What accounting services do most Arizona small businesses actually need?
At least three things are needed from accounting services for small business owners: Arizona bookkeeping services to keep financial records current, tax preparation services in Arizona to file accurately at year-end, and some form of tax advisory to avoid surprises on estimated taxes and deductions. As you add employees, payroll support becomes essential. Very few small businesses need audit services or CFO-level reporting right away.

Does Arizona have any unique tax obligations small business owners should know about?
Yes, Arizona business owners are subject to unique tax challenges and obligations. Arizona imposes a transaction privilege tax, which functions similarly to a sales tax but applies to the privilege of doing business in the state rather than directly to the buyer. Depending on your industry and how you structure your business, transaction privilege tax compliance can be more involved than standard sales tax filing. Professional guidance helps you stay current with both state and local transaction privilege tax rates.

Is a virtual accounting firm a good fit for Arizona businesses outside of Phoenix?
Absolutely. Virtual accounting firms in Arizona serve clients statewide, so business owners in Tucson, Prescott, Flagstaff, Yuma, or anywhere else in Arizona receive the same level of service as those in the Phoenix metro. For owners in smaller markets where local CPA accounting options are limited, a virtual firm often provides better access to experienced professionals than what's available locally.

How do I know when it's time to stop using DIY software and hire a professional?
A few clear signals indicate it's time to stop using software: you're spending several hours per month on bookkeeping instead of running your business; you're unsure whether you're withholding or paying the right amount in estimated taxes; your revenue has grown significantly, or you've added employees; or you've received a notice from the IRS or Arizona Department of Revenue. Any of these situations warrants professional support.

Ready to take accounting off your plate? 1-800Accountant's small business bundle pairs you with a dedicated accounting team that handles bookkeeping, taxes, and year-round advisory support at a flat monthly rate. It's a practical, affordable way to get the financial clarity your Arizona business needs.
