The short version

  • Only Mercury has a free tier, so it costs nothing to try first.
  • Each has a real cost: Mercury treasury access requires a $250,000 balance held with Mercury; Tropic benchmark coverage is concentrated in commonly purchased SaaS, so a company whose spend is dominated by niche, vertical or regionally sold vendors buys intelligence that does not cover its actual contracts.
  • They diverge on capability: Mercury covers Business checking, Tropic covers Contract and renewal repository.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Mercury

  • Treasury access requires a $250,000 balance held with Mercury
  • Non USD international wires carry a 1% conversion fee
  • Choosing OUR wire coding, which covers intermediary bank charges, costs $15 per wire
  • ACH invoicing is $1 per transaction on Mercury Plus and only free on the $299 a month Pro plan
  • Advanced and recurring invoicing require Mercury Plus at $29.90 a month

Tropic

  • Benchmark coverage is concentrated in commonly purchased SaaS, so a company whose spend is dominated by niche, vertical or regionally sold vendors buys intelligence that does not cover its actual contracts.
  • Handing negotiation to a third party can damage a direct supplier relationship that a customer relies on for support and roadmap influence, which is a real cost not captured in a savings figure.
  • Claimed savings are measured against a counterfactual price nobody can verify independently, so the return on the subscription is difficult to audit after the fact.
  • Pricing is quoted and typically scales with spend under management, meaning the fee rises with the very software bill the product is meant to reduce.
  • It is focused on software and AI spend rather than general procurement, so it does not help with services, facilities or physical goods, which for many companies is the larger share of third-party spend.

Answered from the vendors’ own pages

Mercury: Is Mercury business banking free?

Mercury's base banking tier is free and includes ACH payments, domestic wire transfers, real-time payments, Bill Pay, and QuickBooks/Xero automations at no monthly cost.

Source
Tropic: What am I actually buying?

Price intelligence and negotiation capacity, wrapped in a contract and renewal management tool. The benchmark data is the asset; the workflow is table stakes.

Mercury: What does Mercury Plus add beyond the free tier?

Mercury Plus costs $29.90 per month and adds invoice ACH debits, recurring invoice capabilities, invoicing API with 500 calls per month, unlimited 1099 filings, and access to partner benefits.

Source
Tropic: Does it work for niche software?

Less well. Benchmarks are strongest on widely purchased SaaS. Ask for coverage on your top ten suppliers by spend before signing.

Mercury: Does Mercury charge monthly account fees?

No, Mercury states there are no minimum account balance requirements, overdraft fees, required monthly fees, or account opening fees. The free tier includes essential business banking, with paid tiers available for additional features.

Source
Tropic: Can I verify the savings?

Not independently. Savings are measured against an estimated market price, so treat the figures as directional and negotiate the fee accordingly.

Tropic: Does it cover non-software spend?

No. It is software and AI spend. Services, facilities and goods need a general procurement tool.
