Usage from the warehouse, not a CSV ritual. Point it at a replica and a read-only user.

The commercially important pipes today are the warehouse your events sit in, and the channel your team already reads. Payment links belong on the invoice before you send the first one.
The connections
Each row is a working pipe — in or out. Connected means it is feeding. Error means the credentials died. Not configured means nobody finished setup.

Which way it flows
Connect a payment provider before the first send, or the invoice goes out with no pay-now link and you chase bank transfers.
In
Customers from HubSpot, the catalog from Chargebee, usage from PostgreSQL. The point is not to retype what another system already holds.
Out
A pay-now link on the invoice, alerts in Slack, dashboards in Metabase. Sonic does not replace the processor, the chat, or the warehouse.
What connects
Named connections, with the mark you already recognise — not a row of logos with nothing behind them.
Coming in
In
Usage from the warehouse, not a CSV ritual. Point it at a replica and a read-only user.
In
Companies become customers. Clean duplicates before the first pull, or invoices split across both.
In
Catalog and customers for a cutover. Chargebee stays the source of truth until you switch.
Going out
Out
A pay-now link on the invoice. Payouts arrive net of fees — match them in bank rec, not one-to-one.
Out
UPI, cards, netbanking. Without the webhook, money arrives and the invoice stays open.
Out
Billing alerts where the team already talks. A usage spike is worth knowing the same day.
Out
Your dashboards inside Sonic. Scope them per organisation. Do not point them at the live billing database.
On request
Post the journal to the GL you already close in. Sonic stays the bill and the trail — NetSuite stays the ledger of record.
On request
Same shape as NetSuite, sized for a smaller books team. Sonic bills and recognises; QuickBooks stays the ledger.
Not on this list
These are the pipes we have already built. Most B2B stacks add one more: another CRM, another warehouse, another ledger. Tell us what you run and we will scope the connection on the call — building a new pipe is normal, not a blocker to starting.
Health
Connection status is a morning check, not an IT-only page. A warehouse in error is how a usage line goes to zero.
