What is Mercury?
Mercury provides business banking for startups and technology companies through partner banks, including checking and savings accounts, treasury, corporate cards and bill pay. Pricing is quote-based rather than published.
Who is Mercury a good fit for?
Mercury is the better choice for a US startup that wants the bank account itself plus treasury and outbound bill payment in one place, because Mercury holds the funds and pays the bills, whereas Vergo connects to cards the business already holds and does not pay invoices. That is a real answer, not a courtesy — a comparison that cannot say where the other product wins is an advertisement, and it reads like one.
Is the coding AI or rules?
Rules engines file what matches a pattern and queue what does not. Vergo proposes the coding by inference from your own accounting structure and history — no rule library to build, no keyword lists to maintain, and new vendors are coded on first sight, and every coding shows why it was chosen, so a reviewer confirms in seconds instead of re-coding by hand.
What does each product do with the receipt?
Most capture products read the header — vendor, date, total — and leave the coding to a person. Vergo reads the receipt itself, line by line, and predicts the GL account from what was actually bought, not just the vendor name on the header.
When is Mercury the better choice?

Where should you go next?
What is the best alternative to Mercury?
It depends on the line you care about. If you want spend software without taking a new card, the card-agnostic group fits — Vergo is the AI-native option in it. If you want a card-plus-software bundle, several platforms issue their own.
Does switching from Mercury mean changing cards?
No — Mercury and Vergo both work with existing cards. The switch is about the coding engine, not the cards.
Does Vergo handle AP and reimbursements too?
Yes. Card spend, employee reimbursements and AP invoices run through one coding model and sync to your ERP or accounting software. Payment stays on your existing rails.
Which ERPs does Vergo work with?
Every major ERP and accounting system — from QuickBooks and Xero to NetSuite, Sage, and construction systems like Sage 300 CRE, FOUNDATION and Vista.
