# Customising invoices

Customising invoices can enhance your brand identity and improve the overall customer experience.

The Solvimon Platform offers multiple ways to customise your invoices:

* Branding: Incorporate your company's logo, colour scheme, and fonts to maintain consistent branding across all customer interactions
* Template Customisation: Customise the layout and design of your invoice template to align with your brand identity.
* Personalisation: Include personalised messages or customer-specific information to create a more personalised invoicing experience.
* Invoice Numbering: Choose the sequencing for invoice numbering while creating a customer. You have two options for configuring invoice numbers i.e. Single sequence across account OR Unique sequence per customer.  Invoice Prefix default value can also be saved for prefixing the generated invoice numbers.

# Setting up the branding colours and logo

To set up the branding colours and logo for you invoices, go to **Settings > Branding**

* Enter the HEX code for the Primary colour and Secondary colour and the Logo
* For the Logo, upload a PNG/JPEG/SVG file less than 10MB

# Setting up invoice numbering and prefix

Most tax authorities require a sequence of invoice numbers to audit completeness of a set of invoices.

Solvimon automatically creates a sequence invoice numbers. Every new FINAL invoice is assigned an invoice number in the range.

By default Solvimon applies the following structure INV-YYYY-MM-00000x for example: INV-2023-06-000016\
This implies there is a range per year and per month

### Standard invoice numbering

You can set the invoice numbering type in the Invoices section under the Settings menu for that particular customer as shown below.

You can also set the invoice prefix information for all your invoices

### Multiple billing entities invoice number generation

In cases of multiple billing entities, to avoid overlap in the invoice numbers, the reference of the Billing Entity is added in the invoice number generated.

Thus, if there are two billing entities with references `EE` and `LT` then the invoice numbers would be generated as follows -

* INV-LT-2024-08-00001 (for Billing Entity with reference LT)
* INV-EE-2024-08-00001 (for Billing Entity with reference EE)

This prevents in any gaps in the sequence per Billing Entity.

You can also use the following placeholders in the Invoice Numbering configuration. Each placeholder is replaced by its respective value when the invoice number is generated.

| Placeholder                                     | Resolves to                                         |
| ----------------------------------------------- | --------------------------------------------------- |
| `{{billing_entity.reference}}`                  | Billing entity's reference field                    |
| `{{billing_entity.registered_address.country}}` | Billing entity's registered address country code    |
| `{{billing_entity.custom_fields[<ref>]}}`       | Value of a billing-entity custom field by reference |
| `{{customer.custom_fields[<ref>]}}`             | Value of a customer custom field by reference       |

### Credit notes

You can also customise credit note number generation and configure it in the settings menu under invoices.
