Who is actually paying — when the client and the payer are not the same

Most invoices go to the person who answered the door. Most of the time, that person also pays, but not always. A business sends you to the job, and its accounts department settles the bill. A landlord pays for work a tenant only agreed to on the phone. A main contractor books you as one trade of several. Their payment terms, not yours, decide when the money moves. None of that is a problem until you have written the invoice to the wrong name.

Find the payer before you start

The payer is whoever agreed to pay. It is not whoever was on site when you arrived. It is not whoever you have been emailing about the job. Those are often the same person. When they are not, the gap shows only later. An invoice bounces back with “this isn’t who we book with.” Or it goes quiet.

Ask one direct question before you start: who should this invoice actually go to? A client who arranges work for someone else will usually tell you plainly. A business or a letting agent expects the question. It is a normal part of booking a job that someone else pays for. It is not awkward.

The four setups

Almost every job where the payer is not the client on site falls into one of four setups:

• A business. Someone at the company arranges the job and is on site or on the phone with you. Their accounts department pays. The bill often goes against an accounts contact, a purchase order, and a “bill to” name. That name is the legal entity, not the person you dealt with.
• A rental property. A letting agent instructs the work. A tenant is on site to let you in. The landlord pays, sometimes through the agent and sometimes directly.
• A main contractor. You are one trade of several on a bigger job. The contractor who runs it books and pays you. The person who later owns the finished building does not. The contractor’s payment terms rule the job, not yours.
• A third party. A family member, an insurer, or a friend of the client covers the cost. The person you dealt with about the work does not settle the bill.

Whichever it is, the earlier someone names it out loud, the less it costs you later.

What changes on the invoice

Once you know who is paying, a few fields on the invoice change to match the payer. They no longer match the person you did the work for:

• The bill-to name. Use the payer’s own name, or the registered name of the business. Do not use a shortened version you would use in conversation.
• The address and email. Use the place where the payer’s own accounts process expects an invoice. That is sometimes a different address from the job itself.
• A purchase order number. If the business gave you one when it agreed the job, put it on the invoice exactly as given. See what a purchase order actually is if nobody has asked you for one before.
• A site or property reference. Add a short line with the address or job the invoice is for. An accounts team with several properties or sites can then match it to the right one. They do not need to email you to ask.

The client stays the person you did the work for. That record does not change. The invoice gets a separate name and address, addressed to whoever will pay.

The other direction — you hire another trade

The same question runs the other way when you bring in another trade. Before they start, agree four things. Agree the rate. Agree the scope of what they do. Agree the date you will pay them. Agree who invoices whom: you invoice your client for their work, or they invoice you separately. Settle this in writing before day one. It is the same discipline you would want a main contractor to extend to you.

This is about payment logistics. It does not cover their tax or employment status. That is a separate question with its own rules, which depend on where you work. Check it with an accountant. Do not guess.

When nobody pays

Chase the party named on the invoice. Do not chase whoever was on site, or whoever sits higher up the chain. A main contractor may tell you they are waiting to be paid by their own client. That is their cash-flow arrangement. It is not your payment term, unless you agreed to “paid when paid” terms in writing before the job started. Your invoice was addressed to them. Ask them for a date, as you would any other client. See what to do when a client won’t pay if it goes past every reminder.

Common questions

Who do I list as the client if the payer is someone else?

Keep the client as the person or business you did the work for. That is who agreed to the job. Put the payer’s name, address, and email in the invoice’s separate bill-to fields. The invoice then reaches whoever will pay it.

Does a letting agent or a landlord pay the invoice?

Whoever agreed to pay when the job was booked. Ask before you start. Do not assume. A letting agent who instructed the work sometimes pays directly and recharges the landlord later. Other times the agent is only the point of contact, and the invoice names the landlord.

What if the main contractor is waiting to be paid by their own client?

That is their cash-flow arrangement. It is not your payment term, unless you agreed to it in writing before the job started. Your invoice was addressed to them. Chase them directly for a date. Do not wait on a payment chain you are not part of.

Do I need a purchase order number on every invoice?

Only when the business asks for one. Not every client uses them. If they gave you a number when they agreed to the job, put it on the invoice exactly as given. A missing or mistyped purchase order number is one of the most common reasons a company invoice sits unpaid.

Is a subcontractor’s pay tied to when I get paid?

Only if you both agreed to that up front. A main contractor’s “paid when paid” applies to you in the same way: only if you accepted it. Agree the rate, the scope, and a specific pay date before they start. Then their payment does not quietly depend on how fast your own client settles.
