How to invoice a business as a sole operator
You can be one person. They can be a company. The invoice still has to survive accounts payable — not a consumer checkout.
Invoicing a business is not “small business software.” It is a document their AP clerk can match: vendor, PO, amount, tax, due date. A Pay now button does not replace a PO. A client portal they must register for often delays payment.
Ask before you bill
- Legal name on the cheque / EFT, not the brand on the website.
- Billing address and AP email (often not the person who hired you).
- PO number if they use purchase orders. Put it on the invoice.
- Their payment terms. If they say Net 30, do not write Due on receipt unless you agreed.
On the invoice
Everything in what to put on an invoice, plus PO, AP email, and GST/HST if you collect it (GST/HST fields). Canadian freelancers: invoice in Canada.
Send a share link and/or PDF to AP, not a Slack screenshot. Deposits: deposit invoice, then balance.
You stay one user
justIssued is one login. That is enough for a sole operator billing companies. It is not a five-seat AP department. If you need two people in the same books, this is the wrong product. If you need the company to pay by card on the PDF, use someone with Pay now.
