OnchainInvoice is the professional invoicing tool for freelancers and agencies that price in fiat, settle in crypto, and still need clean records.

Built for direct wallet settlement across stablecoins and major crypto rails
The shift
Stripe, Wave, and Coinbase Commerce each solve one part of the workflow. None of them give you fiat-priced invoices, direct wallet settlement, automatic reconciliation, and signed accounting records in one place.
The old way
OnchainInvoice
How it works
OnchainInvoice keeps the invoice workflow recognizable for you and the payment flow simple for your client.
01
Line items, tax, due dates, client details, and branding stay familiar. The crypto complexity stays behind the payment link.
02
They see the invoice total, token options, QR code, and wallet deep link. Funds move directly from their wallet to yours.
03
Monitoring sees the transaction, confirms the amount, updates the invoice, and generates a tamper-evident record for your books.
Product
Track invoices, payments, receipts, supported tokens, and client history without rebuilding the paper trail by hand.
Features
The product is designed around one job: turn a wallet payment into a professional invoice record without busywork.
Edge Functions monitor supported chains and match incoming payments to the right invoice.
Your client pays a wallet you control. OnchainInvoice never holds funds or routes payouts.
Create invoices in familiar business currencies while accepting settlement in supported crypto tokens.
Ed25519 signatures and SHA-256 hashes make records tamper-evident and easy to verify.
Send invoices, deliver receipts automatically, and remind overdue clients without spreadsheet tracking.
Export clean payment and receipt data for bookkeeping, reviews, and month-end reconciliation.
Audit-grade receipts
The signed receipt is the credibility layer. It shows what was paid, when it was paid, what it was worth, and why that value can be trusted.
No reconstructing exchange rates after the fact. The fiat amount is captured when the transaction confirms.
Every receipt carries an Ed25519 signature and SHA-256 hash. Tamper with one byte and verification fails.
The transaction is public, the signing key is published, and the proof can be checked outside the app.
Given the receipt, an auditor can reproduce the transaction, token amount, rate, and fiat total.

Built for
You bill clients across time zones. Wires are slow, FX spreads hurt, and follow-up is unpaid work. Send one USD-priced crypto invoice and give your bookkeeper a clean receipt.
For the freelancer who would rather invoice once and be paid by Tuesday.
When you are running 8 to 20 invoices a month, card fees are not background noise. Keep the margin, send branded payment links, and export the trail at quarter-end.
For teams where 3% on cross-border billing is real operating money.
Your treasury is on-chain and your contractors are global. You should not need a bank in the loop just to issue an invoice and document payment.
For teams whose operations already live wallet-to-wallet.
Pricing
Compare that to Stripe, PayPal, or FX spreads. On a single $5,000 invoice, you have already paid for two years of Plus.
Try the full workflow with no time limit.
For everyone who actually uses crypto invoicing for real.

FAQ
Yes, and most of them prefer them. Each receipt includes the on-chain transaction hash, timestamp, exact fiat value at the moment of payment, and rate source. It is signed and tamper-evident so your bookkeeper, CPA, or auditor can verify it independently.
No. They click your link, see a clean payment page, and either tap pay with wallet or scan a QR code. The page handles token selection and rate conversion automatically.
No. Funds go directly from your client wallet to a wallet you control. OnchainInvoice never touches the money. Revenue comes from the Plus subscription, not from your invoices.
We use a tolerance window to absorb network fees, rounding, and minor slippage. Within tolerance, the invoice auto-confirms. Outside tolerance, it is flagged for review so you stay in control.
The payment page recalculates the crypto amount at live rates when it loads, so your client pays the right fiat-equivalent amount. The receipt locks the rate at the exact second payment confirms.
OnchainInvoice is a documentation tool. It never custodies funds, processes payments, or routes money. Tax treatment varies by jurisdiction, so use the records with your accountant or tax advisor.
Yes. Once crypto is in your wallet, you can off-ramp through Coinbase, Kraken, MoonPay, or another exchange. Or you can hold it as treasury. We do not make that decision for you.
Three free invoices a month, every month. No card, no trial period, no surprises. Outgrow it and Plus is twelve dollars.
