Every Amazon seller faces a critical decision: handle bookkeeping yourself, invest in specialized software, or hire professional bookkeeping services. The choice affects your time, accuracy, costs, and scalability, and there's no one-size-fits-all answer. Use the items below for a weekly bookkeeping review.
This guide compares all three options with honest pros/cons, cost analysis, and a revenue-based decision framework so you can choose the right bookkeeping approach for your business stage and goals.
The approach: track everything manually in spreadsheets or basic tools like QuickBooks/Xero without specialized Amazon integration.
Best for:
The approach: Specialized Amazon accounting software that automates data sync, categorization, and reporting (like Nova).
Best for:
The approach: Hire a dedicated bookkeeper, accounting firm, or CFO service that manages all financial operations for you.
Best for:
| Cost Factor | DIY | Software | Services |
|---|---|---|---|
| Monthly Software/Service | $0-50 | $69-300 | $500-3,000 |
| Your Time (hrs/week) | 10-15 | 2-3 | 1-2 |
| Time Value ($50/hr) | $2,000-3,000/mo | $400-600/mo | $200-400/mo |
| Annual Tax Prep | $500-1,500 | $500-1,000 | Included |
| Total Monthly Cost | $2,000-3,100 | $470-900 | $700-3,400 |
When factoring in time value, software is the most cost-effective option for 80% of Amazon sellers. DIY appears cheap but costs $2,000-3,000/month in opportunity cost. Services make sense at scale or when you need strategic CFO guidance beyond just bookkeeping.
Recommended: DIY with spreadsheets or basic integration tool
Reasoning: at this stage, cash is king. Your time investment (10-15 hrs/week) teaches you the business fundamentals. Use free templates and basic QuickBooks.
Action: Download P&L template, track COGS in spreadsheet, categorize Amazon settlements manually.
Recommended: Amazon accounting software like Nova
Reasoning: you're hitting the scale where manual bookkeeping breaks down. At 10-15 hours weekly, you're losing $2,000-3,000/month in opportunity cost. Software pays for itself 10x over.
Action: Invest in Nova for a P&L with real-time sales and product-level profitability. Hire accountant quarterly for tax planning.
Recommended: Software + quarterly accountant review
Reasoning: you need daily operational intelligence (software) AND strategic tax/financial guidance (professional). Hybrid approach maximizes value.
Action: Nova for day-to-day ($169-299/mo) + ecommerce CPA for quarterly reviews and tax strategy ($500-1,000/quarter).
Recommended: Software + monthly bookkeeping service
Reasoning: Complexity increases with scale (multiple ASINs, team, possibly multi-channel). You need automation + human oversight for accuracy and strategic decisions.
Action: Nova ($299/mo) + monthly bookkeeper specializing in ecommerce ($800-1,500/mo). Consider fractional CFO for growth planning.
Recommended: Full-service CFO + software
Reasoning: at this scale, financial strategy determines your next $5M-10M in value creation. You need sophisticated forecasting, scenario planning, and capital allocation, plus clean books for potential exit.
Action: Nova Enterprise + dedicated ecommerce CFO firm ($2,000-5,000/mo). Focus on EBITDA optimization and exit readiness.
For most Amazon sellers doing $50K-$5M annually, specialized software is the optimal choice. Try Nova free for 14 days and see the time savings and accuracy improvement firsthand.
