The 6 Best Amazon
Accounting & Bookkeeping Firms of 2026, Reviewed

Bean Ninjas is an ecommerce-specialized accounting firm founded in 2015, best known for its deep Xero expertise and focus on 7- and 8-figure online businesses including Amazon FBA, Shopify, and multi-channel sellers.

In our assessment, Bean Ninjas stands out for treating ecommerce accounting as a distinct discipline rather than general bookkeeping applied to online business. Their team is certified in Xero, A2X, and other ecommerce-specific integrations, meaning they understand the nuances of Amazon fee reconciliation, inventory valuation (COGS), multi-currency transactions, and FBA reimbursement tracking. Beyond bookkeeping, they offer virtual CFO services and tax advisory for scaling brands. Pricing is custom-quoted based on business complexity, with engagements typically starting around $500/month as of April 2026 — always confirm current pricing directly with their team.

EcomBalance is a monthly bookkeeping service purpose-built for ecommerce businesses, including Amazon FBA, Shopify, Walmart, and multi-channel sellers. Their model is simple: they deliver your financials by the 15th of each month, every month.

What makes EcomBalance compelling for Amazon sellers at the growth stage is its transparent, flat-fee pricing structure. As of April 2026, services start at $399/month — a refreshingly published starting rate in a market where most competitors require a call just to get a number. You receive an income statement, balance sheet, and cash flow statement monthly. Their onboarding includes a free first month of bookkeeping, which lowers the risk of switching to a new provider. They also offer a pricing calculator on their website to get an instant estimate based on your business volume — a rare level of transparency for a professional services firm.

Catching Clouds was widely recognized as one of the most respected Amazon-specialized accounting firms in the US before merging with Acuity in August 2021. Today, the combined entity operates under the Acuity brand and continues to serve Amazon and multi-channel sellers with specialized ecommerce accounting services.

Acuity's service range spans bookkeeping, accounting, tax compliance, and virtual CFO services — with particular depth in the Amazon channel given Catching Clouds' heritage. As of April 2026, Acuity pricing starts around $479/month depending on service scope and business complexity, scaling up to over $2,000/month for comprehensive CFO engagements. In our research, they are well-regarded for sellers managing simultaneous Amazon, Shopify, and retail channels who need someone fluent in each platform's accounting quirks.

Seller Accountant is a CPA firm that focuses exclusively on Amazon and ecommerce sellers. Their narrow specialization — working only with online sellers rather than a general client base — is the core of their value proposition.

Their services cover bookkeeping, tax preparation, sales tax compliance, and strategic tax planning specifically designed around the realities of Amazon FBA: inventory cost accounting, reimbursements, seller fees, and multi-state nexus. In our research, Seller Accountant is particularly well-regarded by sellers who have previously worked with generalist CPAs who did not understand Amazon's unique financial structure — the specialized knowledge gap is real and Seller Accountant addresses it directly. Pricing is custom-quoted based on service scope; prospective clients can request a free consultation to assess fit. All pricing information should be confirmed directly with the firm as of April 2026.

Avalara is best known as sales tax compliance software, but their managed services offering pairs their platform with expert human tax specialists who handle registration, filing, and remittance on your behalf — making this a true service provider, not just software.

For Amazon sellers with multi-state nexus or international VAT obligations, Avalara's managed tax service is one of the most comprehensive options available. They handle US state sales tax registration ($349/location as of April 2026 for stand-alone registration), ongoing filing and remittance, and can manage VAT/GST compliance for international marketplaces. In our research, this service is best suited to sellers who have grown beyond the point where DIY tax software is sufficient and need professionals to own their compliance obligations end-to-end. This is not a general bookkeeping service — it is a dedicated sales and indirect tax managed service.

Lineal CPA is an ecommerce-focused accounting firm that specializes in tax strategy and financial advisory for online sellers, with a strong content presence that makes them well-known in the Amazon seller community.

Their content output — including detailed guides on ecommerce accounting services — demonstrates genuine subject matter expertise. In our assessment, Lineal CPA is a strong option for sellers who want a CPA relationship that goes beyond compliance and into proactive tax strategy: entity structure optimization, home office deductions, R&D credits relevant to product development, and long-term exit planning. As of April 2026, pricing is custom-quoted based on service scope. A free initial consultation is available to assess fit before engaging.
