Invoices

Invoices are generated from work logs. You select a billing rate type, pull in the relevant work logs for a date range, and Nufinox computes the total amount automatically.

Invoice Rate Types

When creating an invoice, choose one of three rate types:

Hourly

Charges by the hour. The invoice amount is:

rate × Σ (hours logged × employee billing ratio)

If a work log has no hours recorded, 8 hours is assumed. Each employee's hours are multiplied by their billing ratio before summing.

Daily

Charges by the day. The invoice amount is:

rate × number of distinct dates across all assigned work logs

Each unique date across all work logs counts as one billable day, regardless of how many employees worked that day.

Monthly

Charges by the month. The invoice amount is:

rate × number of distinct calendar months across all assigned work logs

Each unique year-month counts as one billable month.

Creating an Invoice

1. Go to Invoices and click New invoice
2. Fill in:
3. Client — who is being billed
4. Number — invoice reference number (must be unique)
5. Currency — defaults to EUR
6. Rate — the per-unit rate (per hour, per day, or per month)
7. Rate type — hourly, daily, or monthly
8. Save the invoice. The amount starts at zero until work logs are assigned.

Assigning Work Logs

After creating an invoice, assign work logs to it:

1. Open the invoice and click Add work logs
2. Enter a start date and end date
3. Nufinox assigns all unassigned work logs for this invoice's client within that date range
4. The invoice amount is recomputed automatically

Work logs already assigned to another invoice are not affected. Only unassigned work logs within the date range and for the selected client are pulled in.

Invoice Amount

The amount is computed and updated automatically whenever work logs are added or removed. You do not enter it manually. The quantity (hours, days, or months) and amount are shown on the invoice detail page.

CSV Export

From the invoice detail page, click Export to download a CSV file of all work logs assigned to the invoice. The export includes employee name, task title, date, hours, and notes — useful for attaching to the invoice as a breakdown.

Accounting Integration (Minimax)

If you have connected a Minimax accounting account (see Integrations) and the client has an accounting customer ID configured, you can push the invoice to Minimax directly from Nufinox.

Creating a Draft

Click Create draft on the invoice detail page. This creates a draft invoice in Minimax and stores the Minimax invoice ID in Nufinox. The invoice is marked as draft.

Syncing Changes

If you update the invoice (add or remove work logs, change the rate), click Sync to push the updated amount to the existing Minimax draft. Syncing is only available while the invoice is still in draft status in Minimax.

Issued Invoices

Once an invoice is marked as issued in Minimax, it can no longer be synced. The status in Nufinox updates to issued automatically when you attempt to sync.
