How it works
How an operation gets into the books
Your companies keep working in QuickBooks, their banks and their own systems. NightlyBooks reads what comes in, books it by your rules and leaves you the cases the rules don’t cover.

Groups
Accounting for a group of companies
Each company keeps its own book and currency. The group level adds what a group needs: ownership, intercompany, eliminations and minority interest.

When one company bills another, the counterpart bill, and the receipt for a payment, is drafted in the other book and waits for your Approve.
- One register for the group
- Customers, vendors, employees and shareholders live in one register shared by every book; group companies are known as such.
- Intercompany entries
- An operation between two companies is recorded in both books at once, and mutual balances can be netted.
- Profit distribution
- A distribution scheme on a canvas: how profit flows to owners, with the payouts drafted for each month.

Translated at the rate of Sep 30, 2026; the translation difference sits in equity.
- Consolidated P&L and balance sheet
- One column per company, then eliminations, then the group. Matched intercompany pairs are eliminated, one-sided items are flagged.
- Minority interest and goodwill
- Noncontrolling interest in P&L and balance sheet. The investment is eliminated against the subsidiary’s equity, with full goodwill amortized over ten years, in US GAAP terms.
- Equity method
- Stakes of 50% or less are carried by the equity method, with their share of profit in the group P&L.
- Sub-groups
- Every group report can be narrowed to a sub-group, for example the European companies or one holding line.
- Presentation currency
- The whole group in one currency, with the translation difference kept in equity where it belongs.
- Intercompany balances
- A matrix of who owes whom inside the group, with books in different currencies translated.
- Dashboards and budgets
- Profitability, cash and balance dashboards, and budget against actual, for each book and for the group.
- Export
- Every report goes to PDF, Excel or CSV.
Sources
Where the operations come from
Connect a source once and give it rules. After that its operations land in the right book on their own.
QuickBooks Online
Every company read continuously, through Intuit’s change feed. Rules decide which document and account each operation lands on.
Banks
Statement files in CSV, Excel or PDF tables, read by a profile you set once. Bank accounts connected through Plaid show their balances and transactions right on the account.
Your own systems
Invoices, bills and payroll accruals arrive through an intake API, each as a document of your form: from Planfix with a button, or from any system that can send a request.
Payroll
Salary accruals per company come in from payroll, with the same people and companies as in the books.
And back to QuickBooks
Invoices and bills made in the book go to QuickBooks with a plan shown first and no duplicates. Parked bank lines get their categories there after your yes, and each change can be undone.
Your next source
A new source is a channel and a document form. No code.

- Month-end board
- A card for every task of the close, per book and for the group: to do, waiting, done, with the reason when a task is accepted as is.
- FX
- Currency and rate on every line, daily official rates, revaluation posted and reversed, realized differences posted when a payment is linked.
- Payments to documents
- Link payments to invoices and bills one by one or in bulk; exact amounts first, then first-in-first-out. A/R and A/P ageing.
- Year-end and period lock
- Close the year and lock the period, so nothing changes in it by accident: from the screen, an import or an AI.
- Reports of each book
- P&L, balance sheet, trial balance, account cards, journal and statements per contact, on accrual or cash basis.
- Dimensions
- Tag lines with your own dimensions, such as projects or departments, and cut any report by them.
Access
Each person sees their part of the books
Roles set access by book, by section and down to a single account. Everyone signs in with a second factor, and every action is on record.

- Two-factor sign-in
- A second factor is required for everyone. There is no self sign-up: people get in only by invitation.
- Every action on record
- Who signed in, what they opened and what they changed. Changes made by AI are logged, and a batch can be undone.
- Keys for systems and AI
- Every key is limited to its books and sections, for viewing or editing, and can be revoked at once.
- Search and phone
- Search across documents, contacts, accounts and operations from one box. The books work on a phone: menus in a drawer, tables that scroll sideways.
