Invoice
An itemised request for payment.
What an invoice is
An invoice is an itemised request for payment. It pairs a line-item table — description, quantity, unit price, and amount — with a subtotal, tax or discount, a bold total, and clear payment instructions.
It is a working document, not a letter. Every part has a job: the invoice number makes it traceable, the bill-to details route it correctly, and the line items justify the total down to the row.
Done well, an invoice gets paid faster because nothing is ambiguous. waxTable designs that clarity into every invoice it generates for your business, in about five minutes for a few cents.
Anatomy of an invoice
Invoice number & dates
A unique number plus the issue and due dates make the invoice traceable and set the payment clock. They sit at the top so both sides can reference the document instantly.
From & bill-to details
Your business name and contact details on one side, the client's billing details on the other. This header tells the reader exactly who is owed and who owes.
Itemised line items
The core table: each row carries a description, quantity, unit price, and amount. This is where the total is justified, line by line, so there is nothing to dispute.
Subtotal, tax & discount
The line-item amounts roll up into a subtotal, then tax is added or a discount applied. Keeping these distinct shows exactly how the final figure was reached.
Total due
The bold, unmistakable number the client pays. It is set apart from the subtotal stack so the eye lands on it immediately.
Payment instructions
How and where to pay — bank details, accepted methods, and the due date. Without this, even a clear invoice stalls.
Notes & references
Purchase-order numbers, terms, or a short thank-you. This block ties the invoice back to the original agreement and the work delivered.
Invoice dos and don'ts
Do
- Give every invoice a unique number and a clear issue and due date.
- Break the charge into itemised line items with quantity, unit price, and amount.
- Show the subtotal, tax, and discount separately before the total due.
- Make the total due the boldest, most prominent number on the page.
- Spell out payment instructions, including method, details, and deadline.
Avoid
- Don't bury the total in a wall of text or align it with the line items.
- Don't merge tax and discount into the subtotal where the client can't check the math.
- Don't omit the bill-to details and assume the client knows the invoice is theirs.
- Don't reuse the same invoice number across two different requests for payment.
- Don't leave off payment instructions and force the client to chase you for them.
The old way vs. waxTable
How Waxe generates your invoice
- 1
Tell Waxe the job
You describe the client, the work delivered, and the amounts owed. Waxe, your AI operations manager, reads it as a request for payment and pulls in your business name and brand. No template to dig up, no blank page to start from.
- 2
Build the header
Waxe assigns the invoice number and the issue and due dates, then lays out your from details and the client's bill-to details. This is the traceable header that tells both sides exactly who owes whom and by when.
- 3
Lay out the line items
Waxe turns the work into an itemised table, one row per item, each with a description, quantity, unit price, and amount. The structure is built so every charge is justified line by line and nothing in the total is left to guesswork.
- 4
Total it up
Waxe stacks the subtotal, applies tax or a discount, and sets the bold total due apart from the rest. The figures are arranged so the client can follow the math from the first line item down to the final number they pay.
- 5
Add payment instructions
Waxe closes the invoice with clear payment instructions and a notes and references block tying it back to the agreement. The finished document is ready to send, generated in about five minutes for a few cents.
Frequently asked
What is an invoice?
An invoice is an itemised request for payment you send a client after delivering work or goods. It carries an invoice number and dates, your from and bill-to details, and a line-item table with description, quantity, unit price, and amount. Below that sits a subtotal, any tax or discount, and a bold total due. Clear payment instructions and a notes or references block close it out. waxTable generates that full structure for your business in about five minutes for a few cents.
What must every invoice include?
Start with a unique invoice number and the issue and due dates, so the document is traceable. Add your from details and the client's bill-to details, then the itemised line items: description, quantity, unit price, and amount per row. Roll those into a subtotal, apply tax or a discount, and show a bold total due. Finish with payment instructions and a notes and references section. waxTable lays out every one of these parts in the correct order automatically.
How is the total on an invoice calculated?
Each line item multiplies quantity by unit price to give a per-row amount. Those amounts add up to the subtotal, which sits above any tax or discount adjustment. Tax is added and a discount subtracted to reach the bold total due that the client pays. Keeping the subtotal, tax, discount, and total visually distinct prevents disputes over the final figure. waxTable arranges this math-ready stack so the total reads as the clear, unmistakable number on the page.
How does waxTable generate an invoice?
You tell Waxe, your AI operations manager, the work, the client, and the amounts. Waxe designs the document end to end: the invoice number and date block, the from and bill-to header, the itemised line-item table, the subtotal-tax-total stack, and the payment instructions. It applies your business name and brand so the result looks like your firm sent it. The whole pass takes about five minutes and costs a few cents, instead of a day of fiddling with a spreadsheet.
What is the difference between an invoice and a receipt?
An invoice is a request for payment sent before money changes hands; it states what is owed and when it is due. A receipt confirms payment that has already been made. The invoice carries the line items, subtotal, tax or discount, total due, and payment instructions that tell the client how to pay. A receipt simply records that the total was settled. waxTable designs the invoice with the payment instructions and references a client needs to actually pay you.
Skip the writing — generate the whole invoice
Waxe drafts it on your brand in about five minutes, then you refine it. From two days of work to a few cents.
Your next invoice, in five minutes
Tell Waxe about the client and get a complete, on-brand invoice to review — the work of two days for a few cents. There is no blank page to start from and nothing to format by hand; you answer a short brief, Waxe does the drafting, and you keep full control of the final document in the editor.
