A cadence with an off switch.
Payment stops the sequence. Unmatched deposits are how you accidentally chase a customer who already wired you.
The mess
The spreadsheet ages drafts. The customer has not seen them.
This is the role: get paid without that sheet. Finance ops is the whole morning loop. Here the job is the chase — and knowing when to stop. A reminder on day 3 of Net 30 looks like you cannot read your own invoice.

Paid in full exits the sequence. A promise to pay holds it. Partial payment skips a stage.
What Sonic does
Configure the sequence once. Payment is the off switch.
Automatic mail stays off until billing contacts are real. A promise to pay holds the cadence. Partial payment skips a stage. Suggested next sentences are operator-approved. You still send them.
How it runs
Sequence, hold, then cash.
The cadence is configured once. A promise holds it. An unmatched wire is not a reason to keep mailing.
01
Sequence
Stages, wait days, and who gets the mail. Automatic send stays off until contacts are real.
02
Hold
A promise to pay pauses the cadence. Partial payment skips a stage. You still approve the next sentence.
03
Cash
Bank rec is the off switch. A full match creates the payment. A partial leaves the remainder in the cadence.
What Sonic does
Send only what's next. Stop the moment cash lands.
Automatic mail stays off until billing contacts are real. The suggested sentence is operator-approved — you still send it. A full match in bank rec creates the payment and is the off switch, not a rule someone has to remember to apply.

Only sent unpaid. Drafts are still yours.
Match the deposit. That is the off switch.
Questions
Open the answer here.
These are the questions this page raises. The full list lives on FAQ.
Which invoices does Watchtower chase?
Only sent unpaid invoices. Drafts and unsent finals are not overdue. Freight with no payment terms is due on the invoice date, so it still gets a suggestion instead of sitting in a pile.
How do bank rec and collections stay out of each other's way?
Watchtower chases what is still unpaid. Bank rec matches deposits to billed parties. An unmatched deposit is cash that already landed — if you don't match it, the cadence will chase a customer who already wired you. Rec is the off switch collections cannot see on its own.
Who is the bill-to on freight?
The shipper. Not the Customer catalog, and not the carrier. Watchtower, bank rec, and the journal use the shipper as the billed party. The mapped column on the file is always who gets the invoice.
