What is a professional invoice?
An invoice is a bill you send a client requesting payment for goods or services. It lists who is billing whom, what was provided, unit prices or rates, totals, taxes if any, payment terms, and how to pay.
Clear invoices get paid faster, reduce disputes, and create a clean paper trail for bookkeeping and taxes.
What every invoice should include
Include your business name and contact info, client details, a unique invoice number, invoice date, due date or payment terms (for example Net 15 or Net 30), line items with quantities and amounts, subtotal, tax if applicable, total due, and payment instructions.
iRunDocs organizes these fields into a printable PDF with a live preview so you can catch missing details before sending.
Invoices vs estimates and receipts
An estimate or quote is a proposed price before work starts. An invoice requests payment after (or as) work is delivered. A receipt confirms payment was received. Using the right document at each stage keeps client communication clear.
