01Grounded
Reviewable before it bills
Contracts, rates, and matches are explicit and shown before anything is issued — not inferred silently inside a model.
Company
A billing platform that fits you.
Sonic AI is built for B2B finance teams who cannot afford an invoice that is wrong, and who have outgrown the spreadsheet plus five tools.
What we are
An AI-native platform for contract to cash.
An AI-native accounts-receivable platform: contracts to schedules (or rated shipments), invoices, collections, cash matching, and revenue entries. Personalised, configurable, and willing to shape around how a company actually bills.
We sell to CFOs, finance heads, and founders — often the same person in the companies we are built for. Daily users are the people who check invoices and mail every morning.
What we are not
- A payment processor
- A tax filing product
- A general ledger of record
- A quoting tool
- A logo wall for a two-person company
Credibility is craft and specificity — not a logo wall.
How we build
Agents draft. You approve.
The rule that shapes every screen: nothing bills, chases, or posts without a person having seen it first.
02Connected
One chain, not six tools
Contract, schedule, invoice, Watchtower, deposit, and journal share the same model, end to end.
03In control
You approve, agents execute
Routine drafts and matches run themselves. You approve the contract and take the exception.
What we hold to
Short rules, held every day.
These are product behaviours, not slogans. Each one is enforced somewhere in the platform — and each one is a reason an invoice is right.
- 01Drafts grow. Sent do not.
- 02Billed is not recognised.
- 03Paid is a claim. A deposit is a fact.
- 04The catalog is the source of truth.
- 05A haul, a rate, a bill.
- Minutes, not weeks
- Signed PDF to a schedule you can review
- 2 GB in ≈ 15 min
- A full usage extract, rated and ready to bill
- One record
- Contract, invoice, cash, and journal share it
- Zero silent edits
- Sent invoices freeze; changes are credit notes
Who we build for
Finance teams that cannot be wrong.
CFOs and finance heads
Own the number and cannot afford an invoice that is wrong. Often the founder in the companies we are built for.
The morning-loop operator
Checks invoices and mail first thing. Sonic drafts the routine; they approve the contract and take the exception.
B2B with mixed pricing
Subscriptions, seats, usage, or freight — enough volume that the spreadsheet plus five tools has become the risk.
