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’s also the person who 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, and their payment terms, not yours, decide when the money moves. None of that shows up as a problem until the invoice is already written to the wrong name.

Find the payer before you start

The payer is whoever actually agreed to pay — not whoever happened to be on site when you arrived, and not whoever you’ve been emailing about the job. Those are often the same person. When they’re not, the gap only becomes obvious once an invoice bounces back with “this isn’t who we book with” or simply goes quiet.

Ask one direct question before you start: who should this invoice actually go to? A client who’s arranging work on someone else’s behalf will usually tell you plainly, and a business or a letting agent expects to be asked — it’s a normal part of booking a job with someone else’s money, not an awkward question.

The four setups

Almost every job where the payer isn’t 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, but their accounts department pays — often against an accounts contact, a purchase order, and a “bill to” name that’s the legal entity, not the person you dealt with.
• A rental property. A letting agent instructs the work and a tenant is on site to let you in, but the landlord is the one who actually pays — sometimes through the agent, sometimes directly.
• A main contractor. You’re one trade of several on a bigger job, booked and paid by the contractor running it, not by whoever eventually owns the finished building. Their payment terms rule the job, not yours.
• A third party. A family member, an insurer, or a friend of the client is covering the cost — the person you dealt with about the work isn’t the one settling the bill.

Whichever it is, the earlier it’s named out loud, the less it costs you later.

What changes on the invoice

Once you know who’s actually paying, a handful of fields on the invoice change to match them, not the person you did the work for:

• The bill-to name. The payer’s own name, or the registered name of the business — not a shortened version you’d use in conversation.
• The address and email. Wherever the payer’s own accounts process expects an invoice to land, which is sometimes a different address entirely from the job itself.
• A purchase order number. If the business gave you one when the job was agreed, it needs to be on the invoice exactly as given — see what a purchase order actually is if you’ve never been asked for one before.
• A site or property reference. A short line noting the address or job the invoice is for, so an accounts team juggling several properties or sites can match it to the right one without emailing you to ask.

The client stays the person you did the work for — that record doesn’t change. It’s the invoice that gets a separate name and address on it, addressed to whoever’s actually going to pay.

The other direction — you hire another trade

The same question runs the other way the moment you bring in another trade. Before they start, agree the rate, the scope of what they’re actually doing, the date you’ll pay them by, and who invoices whom — you invoicing your client for their work, or them invoicing you separately. Settling that in writing before day one is the same discipline you’d want a main contractor to extend to you.

This is about payment logistics, not their tax or employment status — that’s a separate question with its own rules depending on where you’re working, and it’s worth checking with an accountant rather than guessing.

When nobody pays

Chase the party actually named on the invoice — not whoever was on site, and not whoever’s higher up the chain. If a main contractor tells you they’re waiting to be paid by their own client before they’ll pay you, that’s their cash-flow arrangement, 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 the same way you would any other client, and 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 actually did the work for — that’s who agreed to the job. The payer’s own name, address, and email go in the invoice’s separate bill-to fields, so the invoice still reaches whoever is actually going to 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 rather than assuming. 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 landlord is the one named on the invoice.

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

That’s their cash-flow arrangement, not your payment term, unless you agreed to it in writing before the job started. Your invoice was addressed to them, so chase them directly for a date, rather than waiting on a payment chain you’re not actually 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 upfront, the same way a main contractor’s “paid when paid” only applies to you if you accepted it. Agree the rate, the scope, and a specific pay date before they start, so their payment doesn’t quietly depend on how fast your own client settles.
