How Mona works
Set up once. Then she runs every morning at 7am, forever.
Give her your ledger
Connect Xero in two clicks, or upload a simple spreadsheet of your overdue invoices. Mona works out the columns herself.
She chases, politely then firmly
Friendly reminder, firm notice, final notice, then a formal Letter of Demand. Your timing rules, your letterhead, your payment details on every letter.
Money lands, you hear about it
Mona spots payments and celebrates them in your morning report. If a demand gets ignored, she escalates it to you with clear next steps.

Why "Mona"?
Named after a dog who never gave up
Mona was a real dog. When she wanted something, she would jump, bark, cry, climb, even lick, and she would not stop until she got it. And everyone loved her for it anyway. That is exactly the energy your unpaid invoices need: someone in your corner who never lets go, without burning the relationship.
🐾 Read her storyEverything the chase needs. Nothing it does not.
Escalating letters
Four stages ending in a formal Letter of Demand that debtors take seriously. Written by collections people, sent on your letterhead.
Xero sync
Read-only connection pulls unpaid invoices and contacts before every run. Invoices paid in Xero are never chased.
Payment detection
Mona diffs every sync and upload, spots what got paid, and tells you which letter did the convincing.
Focus, not admin
Mona tells you exactly which debtors need your attention and handles the rest herself. Your mornings get a report, not a task list.
When the bark becomes bite
What happens when a debtor ignores even the Letter of Demand? That is when Mona's bark becomes bite, and it is best seen live. Book a demo.
CRM integration
Every letter, payment and escalation pushed to HubSpot, Pipedrive or 5,000 other apps via Zapier or a signed webhook.
