Create Your First Invoice

This scenario-based tutorial walks you through the complete order-to-cash path: enabling prerequisites, creating a product and customer, building an invoice, and confirming the financial outcome. By the end, you will have a posted invoice ready for payment tracking or e-invoice submission.

#Scenario

Acme Trading LLC is a new EGKits tenant in the retail sector. The finance manager needs to bill a walk-in corporate customer for office supplies before month-end close. You will configure the minimum master data, create the invoice, and verify the Accounts Receivable balance.

#Prerequisites

Before starting, confirm the following:

Requirement Where to verify
Tenant admin or Invoicing role Administration > Users > Roles
Catalog module enabled Administration > Modules
Invoicing module enabled Administration > Modules
Fiscal year and period open Finance > General Ledger > Fiscal Periods
At least one tax code configured Finance > Tax Configuration
Company profile complete (legal name, tax ID) Administration > Company Profile

Estimated time: 15 minutes for a user familiar with ERP navigation.

#Step 1 — Review company and numbering settings

  1. Sign in to your tenant and open Administration > Company Profile.
  2. Confirm legal name, default currency, and tax registration number.
  3. Navigate to Invoicing > Settings > Document Numbering.
  4. Verify the invoice series is active (for example INV-{YYYY}-{SEQ}).
  5. Save any changes and note the default payment terms (for example Net 30).

Correct numbering prevents duplicate document errors during posting.

#Step 2 — Create a catalog product

  1. Open Catalog > Products > New Product.
  2. Enter product details:
Field Example value
SKU SUP-A4-500
Name A4 Copy Paper (500 sheets)
Category Office Supplies
Unit of measure Ream
Sales price 45.00
Tax code Standard VAT (or your jurisdiction default)
  1. Set Track inventory if you plan to deduct stock on delivery; otherwise leave as non-stock service item.
  2. Click Save and confirm the product appears in the catalog search.

#Step 3 — Create the customer

  1. Open Trading Partners > Customers > New Customer.
  2. Complete the customer profile:
Field Example value
Customer code CUST-1001
Legal name Horizon Office Solutions
Billing address Complete street, city, and postal code
Tax ID Customer VAT/tax number (if applicable)
Payment terms Net 30
Credit limit Optional — set if your policy requires it
  1. Assign a Salesperson or Account manager if your workflow uses ownership rules.
  2. Save the customer and verify they appear in customer lookup on invoice forms.

#Step 4 — Build the sales invoice

  1. Navigate to Invoicing > Sales Invoices > New Invoice.
  2. Select Horizon Office Solutions as the customer.
  3. Set the Invoice date to today and confirm the due date reflects payment terms.
  4. Add line items:
Product Quantity Unit price Tax
A4 Copy Paper (500 sheets) 10 45.00 Standard VAT
Delivery fee (manual line) 1 25.00 Standard VAT
  1. Review the Subtotal, Tax, and Total in the summary panel.
  2. Add an internal note if approval is required (for example "Month-end billing — approved by manager").
  3. Click Save as Draft to validate without posting.

#Step 5 — Post and deliver the invoice

  1. Review the draft for pricing, tax codes, and customer billing address.
  2. Click Post (or Submit for Approval if your tenant uses workflow).
  3. After approval, choose Send to Customer via email or download PDF.
  4. If e-invoicing is enabled, open Compliance > E-Invoices and submit the document to the tax authority portal.
  5. Record expected payment in Accounts Receivable > Customer Balance and confirm the open amount.

#Step 6 — Verify the financial outcome

  1. Open Accounts Receivable > Customer Statement for Horizon Office Solutions.
  2. Confirm the invoice appears with status Open and correct aging bucket.
  3. Navigate to General Ledger > Journal Inquiry and locate the AR and revenue postings.
  4. Optional: apply a partial payment to validate payment allocation workflow.

#Expected results

Artifact Expected state
Sales invoice Posted, numbered, PDF available
Customer balance Increased by invoice total
GL journal Debit AR, credit revenue and tax payable
E-invoice (if enabled) Submitted or queued with trace ID

#Troubleshooting

Issue Likely cause Resolution
Product not found in invoice lines Catalog module disabled or product inactive Enable Catalog; set product status to Active
Tax amount is zero Tax code missing on product or customer exempt Assign tax code on product; review customer tax profile
Cannot post — period closed Fiscal period locked in GL Open the period or use current open period date
Duplicate invoice number Numbering series conflict Reset sequence in Invoicing settings; avoid manual number override
E-invoice submission failed Invalid company tax ID or portal credentials Update Company Profile; verify e-invoice integration in System Configuration
Customer email not sent SMTP not configured Configure mail provider under Administration > Email Settings
