Agent behaviour is evaluated
Schedules, rates, and cadences are explicit. AI drafts are reviewable. Sent invoices do not mutate.
The AI revenue platform
AI Agents for B2B Finance Teams.
Sonic AI turns what was agreed — and what actually shipped or was used — into invoices that are right, collections that stop when cash lands, and books that tie. Revenue, automated.
Agents need a platform
Context compounds on the chain
The deal, the meter, the shipper match, the deposit — reused, not re-interpreted in the next tool.
Humans stay in the money path
Approve the contract. Send the invoice. Take the collections step. Match the exception.

Run the schedule
The live artefact. Phases, proration, activation gates, amendments. Invoices draft themselves from the schedule — never rewritten once sent.
Everything upstream exists to produce this. Everything downstream is derived from it.

One system. Two grains.

Deployed deal by deal — monthly, by seat, by event, or by shipment — with the catalogs each grain requires.
Honest numbers
We handle the work that matters most
We will not print a DSO percentage we cannot source. These are capabilities, stated as capabilities.
Grounded
Reviewable before it bills
Contracts, rates, and matches are explicit and shown before anything is issued — not inferred silently inside a model.
Connected
One chain, not six tools
Contract, schedule, invoice, Watchtower, deposit, and journal share the same model, end to end.
In control
You approve, agents execute
Routine drafts and matches run themselves. You approve the contract and take the exception.

FAQ

What is Sonic AI?
An AI-native billing platform for B2B finance teams. It reads what was agreed, runs the live billing schedule or rates each shipment, sends invoices, chases the late ones, matches bank deposits, and posts revenue — on one data model, per organisation.
Is this another invoicing tool with a chatbot?
No. The heart of the product is the billing schedule (for subscriptions) and the rated shipment (for freight). Agents read, draft, and suggest; operators approve. Math on amounts is not a prompt.
What's the difference between subscription mode and shipment mode?
Subscription orgs bill from contracts and schedules — phases, seats, usage, activation gates. Shipment orgs bill each movement from a carrier contract and a rate card. Shippers and carriers are separate catalogs. The bill-to on collections, bank rec, and revenue is the shipper.
Will you rewrite an invoice after it has been sent?
No. Sent, paid, void, and final invoices are not rewritten. Corrections are credit notes or a new invoice alongside the original. Drafts and in-progress invoices can still accept lines. Freight has no credit notes — correct the file, or void.
Can we start from a signed PDF?
Yes. Upload the agreement, review the structured result, approve. Sonic can materialise the customer and products on approve rather than forcing a blank catalog first. Time-to-schedule is measured in minutes on straightforward contracts.
