MercuryBUY
The default startup bank — for good reason

Mercury has won the YC and venture-backed startup market with a clean banking experience, free wires, and a credit card with usable rewards. Not a real bank (partnered with Choice + Evolve) but boring in the right ways.

TropicBUY
The full procurement platform — Vendr plus the workflow software

Tropic is what you buy when you want negotiation savings AND a procurement platform — vendor management, contract storage, intake workflows, spend visibility. More expensive than Vendr but more product.

Choose Mercury if...

Any US-based startup, especially venture-backed. The default banking choice for AI-era SaaS founders.

Avoid Mercury if...

Non-US incorporated companies (limited international support), high-volume merchant processing (use Stripe or your acquirer), regulated industries with specific compliance needs (cannabis, crypto issuance).

Choose Tropic if...

Mid-market and enterprise procurement teams that need workflow + visibility, without paying for Vendr-style full-service negotiation.

Avoid Tropic if...

Companies under 200 employees (overkill), full-service negotiation needs (Vendr is purpose-built for that), pure spend tracking (Sastrify is cheaper).
