Everything the note needs, handled.

Interest accrues daily on the balance — rate ÷ 365, US Rule — and posts when a payment does. Before a single real payment moved, the calculation engine was replayed against NoteSmith across a full portfolio’s payment history and matched to the cent.

A late fee accrues into its own bucket, and interest a short payment didn’t cover carries in an accrued-interest bucket that never bears interest itself. A regular payment never quietly swallows either one — you can always see what a buyer still owes, and why.

Pick a good-through date and get the whole figure: the balance, the accrued-interest bucket a balance-only quote would miss, interest to that date, and unpaid fees — with the per diem printed next to it for a closing that slips.

Turn on online payments and each account gets a private payment link — no buyer account or password to manage. Send the link by email or text, or print it on a statement. Your buyer sees what they owe and pays by bank account or card through secure checkout on your own Stripe account, so the money settles straight to your bank. The payment posts into the ledger automatically and the buyer gets an emailed receipt. If a bank payment fails or a payment is disputed, the posting reverses back out automatically and you are notified. You choose how the processing fees are handled: absorb them all, absorb bank-account payments and pass on card fees, or pass the fees to the buyer.

When the year closes, every account gets a year-end statement of the interest your buyer paid — a substitute-1098 statement ready to hand to a tax preparer — generated from the same ledger their payments already live in. Need the whole year for your CPA? One export pulls the full tax pack, CSV included.

A posted payment is never edited or deleted. A mistake gets reversed, with the reason attached, and every entry in the ledger shows who posted it and when.

Desktop servicing software lives on one computer and locks the second person out. Threshold Ledger runs in the browser: your bookkeeper posts payments at the office while you pull a payoff quote from home — same numbers, same minute.

It runs on the phone in your truck and the computer on your desk. No installs, no per-computer licenses, no database file to pass back and forth.

Land sellers who carry the paper

You sell tracts on owner financing and collect the payments yourself. Threshold Ledger replaces the desktop program — and the spreadsheet behind it — with books you can open anywhere. Owner financing, seller financing, land contract: the name changes by state, the monthly payment doesn’t.

Note holders with a portfolio

A handful of notes or a few hundred. Every account keeps its own terms — rate, due day, grace period, late fee — and the portfolio totals roll up on one dashboard, with past-due accounts in front of you.

You service notes for other people. Everyone on your team gets their own login, the audit trail shows who touched what, and your firm’s name and logo head the app when you sign in.
