An accounting system for agencies running on stablecoins.
Multi-chain treasury, crypto invoicing, mass payouts, AML screening, live client budgets and reconciled P&L — in one bookkeeping system, with zero banking friction.
Agency money is global by default. Advertisers settle in stablecoins. Creators and contractors get paid across borders. Media buys fund themselves out of multi-chain wallets. The accounting reality — spreadsheets stitched together with screenshots, hex strings copied between tabs, AML checks done after the fact — hasn’t caught up.
Summer is the catch-up. Invoice in USDT or USDC on Ethereum and Tron. Screen every inflow before it touches your treasury. Pay creators, publishers and contractors in batches with policy-based approval. Track multi-client budgets and read client- and campaign-level P&L without stitching tabs.
We’re built for advertising agencies, creator and influencer agencies, affiliate networks, media buying teams, and performance marketing companies — the operators who move stablecoin money for a living and need finance infrastructure that keeps up.
A short list of operating principles.
- One ledger, one place per wallet & chain
- Treasury, invoicing, payouts, budgets and P&L sit on a single reconciled ledger — not six tools held together with spreadsheets.
- Honest data
- Figures shown in product previews are illustrative until your real numbers fill them. Nothing is dressed up to look bigger than it is.
- Keys stay yours by default
- Summer is an accounting and operations layer, not a custodian. Managed wallets are institutional-custody-backed; self-custody is first-class.
- Compliance is a feature, not a footnote
- AML screening runs on every inflow before funds land. Every approval and movement is logged and exportable.
- Built for the people doing the work
- We design for the finance lead reconciling on a Friday, the ops manager kicking off a payout run, and the partner reviewing client P&L.
