Nummus User Guide

Welcome to the system that will change your relationship with money. Here you will learn how the logic behind Nummus works.

Accounts and Liquidity

Nummus starts with your real money accounts. Whether it's cash, a checking, or savings account, this is where your liquidity lives.

Tip Pro: Personalize each account with your bank icon to quickly identify where your money is coming from.

Initial Balances

When creating an account, you define an initial balance. Nummus will keep this balance automatically updated by adding income and subtracting expenses made.

Card Mastery

A credit card is not extra money; it is a future commitment. Nummus helps you manage it through Invoices.

  • Closing Date: The day the bank closes your month. Nummus uses this date to know which invoice to assign each purchase to.
  • Early Payments: If you pay your card before the closing date, Nummus records it to free up your daily budget immediately.
  • Carryover: If you make a partial payment, the remaining debt is automatically transferred to the next month's invoice.

The Daily Budget

This is the most important metric in the app. It is the magic number that tells you how much you can spend TODAY.

Budget = (Current Cash + Pending Income - Card Debts - Fixed Expenses) / Days to next payment

If this number is positive, you can spend it with peace of mind. If it's negative, Nummus will warn you that you are compromising your future payments.

Automation

Don't waste time recording the same things every month. Use Recurring Transactions.

You can schedule daily, weekly, bi-weekly, monthly, or yearly payments. Nummus will generate them as "pending" and send you a notification a day before so you aren't caught by surprise.

Security & Privacy
