Mercury vs TaxJar FAQ
- Which one is cheaper?
- Mercury starts lower at $35/mo, compared to $39/mo for TaxJar.
- Can I use either one for free?
- Mercury has a free plan. TaxJar doesn't — though they do offer a free trial.
- How do they charge?
- Different approach here. Mercury uses flat-rate pricing, while TaxJar goes with usage-based. That changes the math depending on your team size and usage.
- Which one is a better deal?
- Depends on what you need. Mercury: Mercury is the affordable fintech banking alternative to Brex and Ramp — they're not trying to be the premium play, they're trying to be the obvious default for startups who don't want to deal with a legacy bank. At $0 to start and $350 at the top, they're well below what traditional banks charge for comparable business services. TaxJar: TaxJar sits in the mid-market of sales tax compliance, undercutting Avalara's enterprise-heavy pricing while offering more automation than DIY spreadsheet approaches. They're clearly going after growing DTC and e-commerce brands that have outgrown manual compliance but aren't ready for Avalara's complexity or cost.
