Create an invoice and review its valuation
This article walks through raising an invoice, reading the valuation table, and taking it through to payment. For the background on how recorded hours, status updates and invoice amounts connect, start with Introduction: Status Allocations and Invoice Amounts.
Where to create an invoice
There are two routes:
- Billing → Invoices → Create
- From the project — open the project, go to the Finance tab, and click Create
Creating from the project is recommended. Kompass then pre-fills the Organization, Project, Reference and Details for you.

Choosing the type
Before anything else, pick what you're raising. The Type dropdown offers two options:
| Type | Use it when | Lines must net |
|---|---|---|
| Invoice | You're billing the client | Positive |
| Credit Note | You're crediting the client | Negative |
Two rules worth knowing up front:
- Kompass checks the sign. If you choose Invoice and your amounts net negative, it won't save, you'll get an error asking you to fix the type or the amounts.
- The type is fixed once saved. You choose it when creating; afterwards it's read-only. If you picked wrong, delete the draft and start again.
Looking for Reallocations (Journals)? Reallocations (moving invoiced value between proposal items without billing the client) aren't created here. They have their own Billing → Reallocations area. See Reallocations.
The Details section

| Field | Description |
|---|---|
| Organization (required) | The organization the invoice is raised for. Only organizations with unlocked projects are listed. If yours is missing, its projects may be locked. When an accounting integration is enabled, only organizations with an accounting reference appear. |
| Project (required) | The project being invoiced. The dropdown shows each project's Work in Progress, and once selected, WIP appears as a hint under the field, a quick sense-check that you're invoicing the right project. |
| Type (required) | Invoice or Credit Note. See above. |
| Invoice to credit | Credit notes only. The invoice this credit note settles. See Raising a credit note. |
| Reference (required) | Auto-generated from the project reference plus a running number: 24-0871-01 for invoices, 24-0871-C01 for credit notes. You can overwrite it, Kompass won't clobber a manual edit. |
| Sales Order | The client authorisation this invoice draws against. See Naming a Sales Order. |
| Date (required) | The invoice date. Defaults to today. |
| Due Date (required) | Defaults to the invoice date plus your organization's payment days (shown as a suffix on the field). Changing the invoice date shifts the due date by the same number of days. Invoices only. |
| Billing & Timesheets Start / End | The period the work covers. Required if your invoice document includes timesheets. The End date also drives the valuation figures, see below. |
| Details | Free text. Defaults to the project name. |
| Invoice Contacts | Who receives the invoice. Prefilled in priority order: the project's invoice contacts, then the billing organization's billing contact, then its primary contact. |
| Attach File | Files to send to the client alongside the invoice. |
| Synchronize | Whether this invoice syncs to your accounting software. Once it has synced, this can't be turned off. |
| Notes | Internal notes. |
| Tags | Searchable tags. |
Watch for the amber warning. If the invoice's Organization differs from the project's billing organization, Kompass flags it under the field. That's sometimes deliberate, but usually not.

The proposal item allocation table
This is where you decide what to invoice, and it doubles as the project's valuation at a glance.

Each proposal item takes one row, and splits into a sub-row per nominal account, so a single item can be invoiced across Core and Subcontract independently.
| Column | Description |
|---|---|
| ID | Proposal item ID. Links through to the item. |
| Name | Proposal item name. Carries a Non-billable badge where applicable. |
| Department / Service | The item's department and service. |
| Type | Lump sum or rate. |
| Price / Tax | The item's total price and VAT rate. |
| Nominal Account | One sub-row per account (Core, Subcontract, and so on). |
| Price | Price for that nominal account. |
| Status Value | The value earned so far, from the latest status update. |
| Invoiced Net | What's already been invoiced. |
| Remaining Value | Status Value − Invoiced Net. What's still available to invoice. |
| Amount Net | What you're invoicing now. The only column you type in. |
| Amount Tax | Calculated automatically as Amount Net × the item's VAT rate. |
The arrow shortcut
Click the arrow inside any Amount Net field to copy that line's Remaining Value straight in.
Note: On a credit note, the arrow copies the Remaining Value as a negative amount. That's intentional, credit notes net negative.
Reading the table
Three situations you'll meet, using the example below:

- Proposal item 194151: Status Value is $4,300 but $4,800 has been invoiced. We've over-invoiced by $500, so Remaining Value shows $(500) — a credit sitting on that item.
- Proposal item 194171: Status Value is $498.45 and $200 has been invoiced, so $298.45 remains. We invoice it in full.
- Proposal item 194237: Status Value is $262.50 and a $100 credit note was raised previously, so Invoiced Net is −$100 and $362.50 remains available.
Four behaviours that surprise people
1. Set a Billing End date and the figures snapshot to it. Every valuation column gains an @ 30/06/26 suffix and shows the position as at that date, not today. This is what makes month-end invoicing accurate. But change the end date and the whole table moves.
2. "Show all" reveals hidden rows. In view mode, Kompass hides proposal items with nothing allocated on this invoice. Tick Show all to see everything. (The footer total always includes hidden rows, and says so.)

3. Editing an existing invoice changes the Invoiced figures. When you click Edit, the Invoiced Net and Remaining Value columns exclude this invoice's own lines. In view mode they include them. This is deliberate: while editing, your amounts appear in the Amount Net column, so counting them in Invoiced Net too would double them up. It does mean the same invoice reads differently in view and edit mode.
4. Unaccepted proposal items are struck through and left out of the price total. A warning triangle appears in the footer to tell you the total excludes them.
The Invoiced column with credits applied
Where a credit note has been applied, the Invoiced column shows the net figure, then breaks it out with two chips: I for the invoiced portion and C for the credited portion. The footer does the same.

Naming a Sales Order
If the project has Sales Orders, select the relevant one in the Sales Order field. This links the invoice to the client's authorisation, and the invoice's net value then draws that order down.
Kompass warns you as you approach the limit:

| Warning | Meaning |
|---|---|
| Near full (amber) | Invoicing has reached 90% of the authorised value |
| Over cap (red) | Invoicing has exceeded the authorised value |
Both are advisory, Kompass won't block the save. They're there so you can check with the client before over-invoicing their PO.
Only live (non-closed) Sales Orders are selectable. If the project has none, the field reads No sales order. See Sales Orders.
Saving and the approval workflow
Complete the form and click Save. The invoice is created as a draft.

From there:
- Submit: when you need a colleague to check what's about to be invoiced.
- Approve: when you can confirm the invoice is correct and can go to the client.
- Post: when you're ready to finalise it and record it in your accounting system. This makes it part of the official financial record.
You can also:
- Reject a submitted or approved invoice. Saving a rejected invoice returns it to draft. The Save button reads Save as draft.
- Void an approved or posted invoice. Once posted, voiding is the only way to cancel it, it can't be deleted or rejected.
You don't have to follow every step. If your permissions allow, a draft can be approved or posted directly. Each action lets you leave a note, and the date, user and note are recorded on the invoice.

Kompass can email selected employees whenever an invoice changes state. Ask your administrator to set this up.
Sending the invoice and getting paid
Once an invoice is approved or posted:
- Documents: generate the invoice document from one of your organization's templates, as Word or PDF, and email it to the client. Recipients prefill from the Invoice Contacts. Any files attached to the invoice can be sent along with it.
- Mark as Sent: record that the invoice has gone to the client, with the date, who sent it, and any notes.
- Payments: as payments come in and are allocated, they appear in the Payments section on the invoice.
Note: Document templates that include timesheets need the Billing Start and End dates filled in. Without them, those templates are greyed out.
Raising a credit note
Credit notes can be created from the invoice page or from the invoice they credit. Open the approved or posted invoice, scroll to the Credit Notes section below Payments, and click Create.

Kompass then:
- Opens a new record with the type already set to Credit Note.
- Sets Invoice to credit to the invoice you came from.
- Fills in every line automatically, copying the original invoice's proposal items and nominal accounts with the amounts negated.

Adjust the amounts to whatever you're actually crediting and save. You don't have to credit the whole invoice, and you don't have to leave the value on the lines Kompass seeded. If you'd rather book it against a different proposal item, move it. The credit still attaches to the right invoice.
A few rules:
- You can only credit an invoice whose value is recognised. Approved (or whatever status your organization treats as value), and not voided or rejected.
- Paid invoices can still be credited. A credit against a paid invoice is a refund.
- You can't over-credit. Kompass caps the total credit at the invoice's net value.
- A credit only takes effect once it's approved. A draft credit note doesn't reduce the original invoice yet.
The Credit Notes section lists every credit applied, with a total. On the credit note itself, the Credits Invoice field links back to the original.
Unapplied credit notes
A credit note doesn't have to be attached to an invoice. Leaving Invoice to credit empty creates a standalone credit that still reduces the proposal item's invoiced value.
Unattached credits are easy to lose track of, so Kompass flags them with a broken-link icon in the invoice list, and there's an Unapplied Credit quick filter to find them all.

Locking and editing
An invoice stops being fully editable when:
- Payments are linked to it
- Accounting transactions are linked to it
- It's been posted (unless you have the permission to edit posted invoices)
A red banner tells you which applies: "Invoice locked because payments are linked to it. Only some fields editable." You can still edit notes, tags, contacts and files, but not the amounts.
Approved invoices need a specific permission to edit. If you have it, the Edit button reads Unlock & Edit.
Deletion is blocked once an invoice is locked.
Reviewing the project valuation
After changing an invoice's state, Kompass returns you to the project. The valuation table on the Finance tab shows where the project stands overall.

| Column | Description |
|---|---|
| Department | Department and nominal account. Proposal items sharing both are aggregated. |
| Last Update | The most recent status update by the project manager. |
| Price | Price of all proposal items in that department and nominal account. |
| Valuation | Value earned, from status updates. |
| Invoiced | Amount invoiced. |
| WIP | Valuation − Invoiced. Positive means work done but not yet billed. Negative means you've invoiced ahead of the work, effectively a credit position. |
WIP is the number to watch at month end: it tells you what you've earned but haven't yet turned into an invoice.
