Stablecoin invoicing for solo subcontractors

If you're a sole proprietor — often in LATAM or elsewhere abroad — paid solely in stablecoins by the firms you subcontract for, you still need real books: what you invoiced, what you were paid, what you owe in expenses, and what you actually earned. A spreadsheet works until it doesn't. Economico lets your AI agent invoice those firms, record USDC payments, and keep clean books as a team of one. Here is how it works.

Books for a team of one

Being solo doesn't remove the need for books — it just removes the person who'd keep them. You're paid in stablecoins, your clients are firms that want a proper invoice, and at some point you need to know your real income and expenses. Economico gives your agent the tools to run that: invoice in dollars, get paid in USDC, record your own costs, and see what you earned — no bookkeeper, no dashboard.

How it works

Invoice the firm. Your agent sends a $4,000 invoice to a consulting firm you subcontract for; AR and revenue post.
Get paid in USDC. The firm pays 4,000 USDC; your agent records it at its dollar value against the invoice, moving AR to cash.
Track your own costs. Record the tools and services you pay for; your agent shows real income, expenses, and what you earned this month from one ledger.

This is the other end of the loop in stablecoin invoicing for consulting firms: when a firm pays you, both sides can keep their books on Economico.

Where it fits — and where it doesn't

This fits a sole proprietor with clean services revenue paid in stablecoins who wants real books without hiring anyone. It's not built for high transaction volume, inventory, or complex multi-entity setups. And Economico is open to Y Combinator founders today — solo subcontractors in the YC-founder network qualify; broader availability comes later. If you mainly need a payment tool rather than books, a payments-first product like Request Finance may be enough — see Economico vs Request Finance — or, for a single zero-signup stablecoin payment link with no account at all, Flow (flow.link), covered in Economico vs Flow.

Frequently asked questions

I'm a team of one — do I really need double-entry books?

If firms pay you and you have expenses, real books make income, costs, and taxes clear — and Economico's agent keeps them for you, so the overhead is roughly asking for an invoice.

Can I invoice in USD and get paid in USDC?

Yes — invoice in dollars, record the USDC receipt at its dollar value, and the journal posts automatically.

Do my clients need Economico too?

No. But if a firm you work for is also on Economico, both ends of that invoice live on the same platform — that shared loop is deliberate.

Is this only for crypto people?

No — it's for ordinary subcontractors who happen to be paid in stablecoins because their clients abroad prefer them.
