Creating an Invoice

How to create an invoice, choose the customer, select charge rows, and understand what Work Planner includes by default.

Work Planner Team12 April 2026

Click New Invoice from the invoices list to open the create invoice popup. Work Planner builds invoices from charge transactions, so this flow is really about choosing the right customer first and then picking the charges that should be turned into invoice items.

Customer

  • Customer: This is required. Until a customer is selected, Work Planner cannot show any charge rows to invoice.
  • Select customer button: Opens the customer selector popup so you can search and choose the right customer without leaving the invoice popup.
  • Open customer button: Once a customer is chosen, the second button lets you open that customer record directly if you need to check details before invoicing.

If you started from a job-driven or debt-driven flow, the popup may already know which customer and job you mean. In that case, Work Planner shows a blue job summary block and preselects the charges from that job where it can.

Select Transactions to Invoice

  • Default charge list: By default, Work Planner shows unpaid charge rows that are newer than the customer's last payment. That keeps the invoice suggestion aligned with what is still outstanding instead of pulling in old charges unnecessarily.
  • Invoice column: If a charge is already linked to another invoice, Work Planner shows that invoice reference and status. Those rows stay visible for context but they are not selectable again.
  • Select All and Deselect All: Useful when you want to invoice everything shown or start from a blank selection and pick only a few rows.
  • Show Historical: Turn this on when you need to go further back than the default unpaid-and-newer-than-last-payment view. It brings older charge rows into the table so you can include them deliberately.
  • Net Amount, VAT Rate, VAT, Gross Total: These figures help you see exactly what the selected charges will turn into before the invoice is saved.

Selection Totals

As soon as you tick one or more rows, Work Planner shows a running summary of how many charge rows are selected plus the net total, VAT total, and gross total. This is the easiest place to spot that you have missed a row or picked too many before saving the invoice.

Additional Invoice Details

  • PO Number: Use this when the customer expects their purchase order number on the invoice.
  • Company Name Override: Leave this blank in normal use. Fill it only when the invoice needs to show a company name different from the customer's stored company field.
  • Note: Adds an optional invoice note that appears on the invoice record after save.

What Happens When You Save

  • Invoice reference: Work Planner generates the next invoice reference for that business automatically.
  • Invoice items: Each selected charge row becomes an invoice item in the same order you selected it.
  • Ledger links: The selected charge rows are linked to the new invoice so they are no longer treated as uninvoiced charges elsewhere.
  • Status: New invoices start as Open.

Validation That Stops the Save

  • No customer: You cannot create the invoice without a customer.
  • No selected charge rows: At least one charge row must be selected.
  • Invalid charge mix: The selected rows must belong to the chosen customer and must still be available to invoice.
  • Invoice Items and Job Linkage: Explains how the selected charge rows become invoice lines and keep their job links.
  • Editing an Invoice: Use this when the invoice has already been created and you need to change its status or notes.
  • Invoice Detail View: Shows what you can inspect after the invoice is saved.
  • Transactions List: Helpful when the right charge rows are missing from the create popup and you need to inspect the finance records behind them.
