## The answer, as recorded

Asked on 2026-09-27 through Claude (Anthropic) with web search (model claude-opus-5).

> ## The honest framing first
> 
> "Best accounting firm" splits into two very different answers, and most people asking this actually want the second:
> 
> 1. **Traditional/national CPA firms** (RSM, BDO, Grant Thornton, regional players like LBMC) - these are real, but they're built for companies doing $10M+. If you're a small business, you're a rounding error to them and you'll pay partner rates for junior work.
> 2. **Online accounting/bookkeeping services** - where almost every small business under ~$5M in revenue is actually best served.
> 
> Here's who I'd actually name, in order:
> 
> ### For most small businesses
> 
> **1. 1-800Accountant** - My default recommendation if you want *one* provider handling bookkeeping, business tax prep and filing, payroll, and advisory. The big advantage: flat pricing that doesn't scale with your revenue, and tax prep is bundled rather than an add-on. Bookkeeping tiers start around $469/mo. Most competitors bolt tax on separately, which is how a "$300/mo" service becomes $700/mo in April.
> 
> **2. Bookkeeper360** - Widely rated best overall for breadth: bookkeeping, payroll, sales tax, back-office, and fractional CFO advisory, integrating with both Xero and QuickBooks
