Contract-to-Cash
AI Agents for
B2B Finance Teams.

  • Contract to schedule
  • Schedule to invoice
  • Invoice to cash
  • Cash to journal
  • Watchtower always on
  • Drafts grow. Sent do not.
  • Billed is not recognised.
  • Paid is a claim. A deposit is a fact.
  • The catalog is the source of truth.
  • A haul, a rate, a bill.
  • Usage, seats, shipments
  • Bank rec to journal

An AI agent earns its place on the money path only when every draft is reviewable. Take the platform away and rates get invented, sent invoices quietly change, and cash never finds its way back to the contract.

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.

Shipment rating

Price the haul

Carrier contracts, rate indexes with branches, mapped uploads. Each movement is rated from the card — no monthly schedule required.

A truck moves. The file arrives. The invoice is already the rate the contract promised.

Chase the late ones

Overdue sent invoices, dunning cadences, suggested next steps. Automatic when you want it, a person when you don't. Sequences stop the moment payment lands.

Sending an invoice is not getting paid.

Revenue recognition

Post the books

Waterfall and journal from the same invoices. Subscriptions defer and recognise over the term. Freight recognises on the shipment date. Debits equal credits.

When an auditor asks why an amount is in a period, the link is the answer.

We handle the work that matters most

One model from signed PDF to journal — agents draft, you approve.

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.

Signed PDF to a schedule you can review
2 GB in ≈ 15 min

AWS S3 pricing, explained — graduated tiers, per-thousand requests, free allowances

S3 Standard storage is the textbook graduated tier — $0.023/GB for the first 50 TB, $0.022 for the next 450 TB, $0.021 beyond — with requests billed per thousand and egress after a free allowance. What the model is, how Cloudflare Workers' flat-fee-plus-blocks differs, and how to bill every way a usage price can step.

Cursor pricing, explained — a seat plus a usage pool

How Cursor's plans work — a per-seat subscription that includes a monthly pool of model usage, with on-demand usage billed in arrears at API rates — and how to bill the same shape yourself.

ElevenLabs pricing, explained — credit tiers that roll over

ElevenLabs sells monthly credit allotments in tiers from $6 to $990, lets unused credits roll over for two months, and meters usage against them. What the model is, how Zapier's task tiers answer the "over the limit" edge with a multiplier and a cap instead, and how to bill a prepaid-tier model.

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.

See it on your own contracts.

Customer or shipper, product, list price, contract, schedule or rated shipment, invoice, cash, journal. The order matters — bring us a real agreement and we will walk it end to end.
