Corrections

Not every invoice is paid in full, on time, or at all. Novex keeps four separate surfaces for the money that moves after a document is issued, and they are deliberately separate: each one answers a different question, and folding them together would make an invoice’s balance impossible to explain.

Surface	What it records	Where it shows up
Write-off	Debt you have decided to stop chasing, on one invoice	That invoice’s balance, and the Written off figure on the invoices list
Adjustments	One-off corrections and miscellaneous income, with no invoice behind them	The adjustments ledger and the profit-and-loss basis
Installments	A repayment schedule against a liability or a vendor bill	Cash-flow forecasting and the installments screen
Debt register	Obligations carried over from previous years	The debt register, and outflow in forecasting

Writing off part of an invoice

Open an issued invoice and use its write-off action. A write-off takes an amount and a reason, and the reason is required — a balance that changed without an explanation is the thing an audit asks about first.

A partial write-off reduces the balance and leaves the status alone.
A write-off that settles the remaining balance closes the invoice.
Novex will not let you write off more than the invoice still owes, counting any credit notes already issued against it.

The invoices list totals every write-off into its own Written off figure, so the top of the screen reconciles: invoiced − paid − written off − credited = open.

Adjustments

The Adjustments screen: a form for type, amount, currency, effective date and a required note, and beneath it a ledger of three entries — misc income, a correction, and a write-off shown as a negative amount — each with its effective date, type, amount, note and an archive action.

Finance → Adjustments is for money with no document behind it. Each entry carries a type, an amount, an effective date and a note — and the note is required here too.

Write-off — bad debt with no single invoice to attach it to.
Correction — a figure that has to move because something was recorded wrongly, or arrived after the fact.
Misc income — money in that is not an invoice.

Sign matters. Enter a negative amount for anything that reduces the position and a positive one for income; the form says so under the amount field, and the ledger colours them apart.

Installment plans

The Installment plans screen: a create-plan form asking what to attach the plan to, its source, total amount, number of installments and first due date, and below it a plan against a vendor invoice showing three installments with due dates, amounts and paid or due status.

Finance → Installments turns one obligation into a schedule. Attach a plan to either a liability from the debt register or a vendor invoice, give it a total, a count and a first due date, and Novex generates the installments.

Each installment is then marked paid as it goes out — and the ones still ahead are what forecasting counts as expected outflow. A plan can be archived once it is finished; the installments stay for the record.

The debt register

The Debt register: a form for adding a liability with an optional linked vendor, creditor name, original amount, amount already paid, year incurred and currency; a Next step card naming the largest remaining obligation; a recent-activity list; and a table of two creditors with original, paid and remaining amounts.

Finance → Debt Register carries past-years obligations being paid down, in the product’s own words — money owed that predates the events you are running now, tracked against either a vendor or a plain creditor name.

Link a vendor where there is one, or use a free-text creditor name where there is not.
Original amount and already paid give the remaining balance.
Year incurred records when the obligation arose. It orders the register and is what distinguishes a 2025 debt from a 2026 one on screen — it is a label, not a filter, so it does not by itself exclude the liability from anything.

A Next step card sits beside the form naming one obligation to chip away at, so the register opens on something to do rather than on a table.

What is not here

Credit notes are not adjustments. A credit note is a document in its own right — it has a number, it is issued against a specific invoice, and it appears in the invoice’s Credited total rather than in the adjustments ledger. See Invoices.
