A web3 agency invoice bills smart contract development, security audits, and protocol maintenance retainers, with a stablecoin payment option since much of this client base transacts natively in crypto.
Development vs. audit line items
Kept separate, since audits are often billed on delivery of the report and may be held back until development milestones are met.
Network for stablecoin payment
The specific chain and wallet address if offering a stablecoin payment option.
Confirmation policy
A note that the invoice is marked paid only once a stablecoin payment is confirmed on-chain.
Copy this into your own document, or open it directly as a branded starting point in Hanko. Bracketed text like [Client Name] is a placeholder to fill in.

Yes — audits are typically billed on delivery of the report, and separating the line items makes clear what each phase of work actually cost.
Only once the transaction is confirmed on the specified blockchain network — never mark the invoice paid based on a client's message alone.
