First-dollar offer for overdue invoices
A fast paid check for freelancers, agencies, contractors, and bookkeepers with messy receivables. We flag overdue invoices, possible paid-but-still-open items, partial payments, remaining balances, and the next relationship-safe follow-up to send.
No accounting login. No subscription. Use anonymized CSV rows or screenshots.
Catch invoices that may already be paid, partially paid, or stuck because the payment reference did not match.
Each row gets a follow-up stage, next contact date, and a plain English reason for the recommendation.
Reminder drafts stay friendly first, then become firm only when the invoice age and contact history justify it.
Sample report
The Quick Check is designed to be small enough to buy today: send a few anonymized rows and get a practical recovery queue, not a generic article about collections.
INV-1001
Payment reference contains INV-1001 and matches the full amount.
Likely paid, still open
Confirm payment reference, then mark invoice paid before sending another reminder.
INV-1002
$300 payment found against a $750 invoice.
Partial payment
Send a friendly note for the $450 remaining balance and ask for expected payment date.
INV-1004
Multiple prior contact attempts and no matching payment found.
60+ days overdue
Escalate from email to phone or owner-level follow-up within 2 business days.
Low-price entry
Existing A/R tools often start at monthly plans. This is a one-time diagnostic for one messy sample, priced to remove the first-order risk.

Partial payment, unapplied payment, duplicate, deposit, credit, or fee mismatch.
Friendly, firm, or final notice. We keep relationship risk visible.

Hi Northwind Agency, I wanted to follow up again because I still have this invoice marked as open. Invoice INV-1002 shows an open balance of $450.00 and appears to be 10 days overdue. Could you confirm whether payment has already been sent, or share the expected payment date? Thanks, Your name

Hi River City Builders, I am following up before we escalate this internally, since this invoice is now over a month overdue. Invoice INV-1004 shows an open balance of $2400.00 and appears to be 47 days overdue. Could you confirm whether payment has already been sent, or share the expected payment date? Thanks, Your name
