Your cash is sitting in someone else's inbox.
Melenyn syncs every open invoice from NetSuite, QuickBooks, or Xero, follows up with a tone and cadence matched to each account's payment history, and tells you which week the money actually lands. No more polite BCCs from a spreadsheet.
Built for finance teams at B2B companies doing $5M to $200M in revenue.

What Melenyn does
Collections is a system, not a person with a spreadsheet.
Today it works because one AR person remembers everything. Melenyn turns that memory into software: every invoice tracked, every follow-up sent on schedule, every promise held to a date.
Dunning that reads the room
Sequences adapt to each account. A customer who pays at day 35 like clockwork gets one light nudge. A serial 80-day payer gets a firmer cadence that starts before the due date, with escalation to their account manager built in.
You approve every template once. Melenyn handles the sending, the timing, and the awkward third reminder.
A payment portal customers actually use
Every reminder links to a branded portal where customers see their open invoices and pay by ACH or card, or grab wire details, in about a minute. No login wall, no "please find attached."
They can also flag a dispute or log a promise to pay, which Melenyn tracks to the day and follows up on if it slips.
A cash forecast you can defend
Melenyn scores each open invoice on the account's real payment behavior, then rolls it up into a week-by-week collection forecast. DSO, aging, and promise-to-pay performance sit on one screen.
When the board asks about cash, you answer with a model, not a hunch.
How it works
Live in an afternoon, not a quarter.
Melenyn sits on top of the accounting system you already run. There is no data migration and nothing for your customers to install.
Connect your accounting system
Authorize NetSuite, QuickBooks, or Xero with a read-and-write connection. Melenyn pulls open invoices, credit memos, and two years of payment history in about 20 minutes, then stays in sync continuously.
Approve your sequences
Review the follow-up sequences Melenyn drafts for each customer segment, edit the wording so it sounds like you, and set the escalation rules. Nothing sends until you turn it on.
Watch cash arrive on schedule
Reminders go out on time, every time. Payments land through the portal and reconcile back to your ledger. Within a month you have a collection forecast built on how your customers actually behave.

FAQ
The questions every controller asks first.
Will this annoy my customers?
This is the question we designed the product around. Melenyn is not a blast tool. Reliable payers get fewer, lighter touches than they probably get from your team today. Only accounts with a real pattern of paying late see firmer cadences, and every message reads like it came from your AR team, because you wrote and approved the templates.
You can pause any account with one click, and sensitive accounts can be set to draft-only, where Melenyn prepares the email and a human sends it.
How are payments processed?
Payments run through Stripe, our PCI DSS Level 1 payment partner. Customers pay by ACH debit or card inside your branded portal, or copy your wire details for bank transfer. Funds settle to your existing bank account, and Melenyn writes the payment back to NetSuite, QuickBooks, or Xero so reconciliation stays clean. Melenyn never holds your money.
How long does setup actually take?
The accounting connection takes about 20 minutes. Reviewing and editing your sequences usually takes a couple of hours spread over a few days. We scope every early access onboarding so your first automated reminder goes out within a week of signing up, with zero engineering time on your side.
What happens when an invoice is disputed?
The moment a customer flags a dispute in the portal, or your team marks one internally, all reminders on that invoice stop. The invoice moves to a dispute queue with a note of what was raised, the right owner gets notified, and sequences resume only after you resolve it. Disputed dollars are also broken out separately in your forecast, so they stop polluting your numbers.
Do you replace my AR person?
No. Melenyn does the part of the job software should do: remembering, sending, tracking, and forecasting. Your AR person keeps the part that needs a human, which is judgment calls, relationships, and the hard conversations. In practice they go from chasing 200 invoices to managing 15 exceptions.
DSO does not fix itself.
We are onboarding a small group of early access teams before general launch in Q4 2026. Early access pricing is locked for your first two years. Tell us about your AR setup and we will reply within one business day.
