Invoice from the job, not from the kitchen table

The single biggest delay in most small shops is the gap between finishing the work and writing the invoice. The work is done Tuesday, the paperwork happens Sunday night, the invoice lands Monday — six days gone before the clock even starts.

Raising it before you leave removes that gap entirely, and it is also when the job is freshest. Nobody is reconstructing on Sunday which parts went in on Tuesday.

Take the card while you are still standing there

An invoice with a payment link is paid faster than an invoice with bank details, and an invoice paid on site is paid faster than either. The customer has just watched you do the work and is at their most willing to settle up.

Card processing costs a percentage, and that is a real cost — but it is almost always smaller than the cost of money arriving six weeks later, and far smaller than the cost of money that never arrives. The card fee calculator works out what a fee actually costs on a given job if you want the number rather than a feeling about it.

Agree the terms before you start, not on the invoice

Payment terms that first appear at the bottom of an invoice are not terms, they are a hope. They belong on the quote, where the customer agreed to them.

Say when payment is due, what happens if it is late, and for a larger job, what the deposit is and when the stage payments fall. On a job big enough to hurt, a deposit before materials are ordered is normal and nobody is offended by being asked.

Send it to the person who actually pays

For a homeowner this is obvious. For anything commercial it is the thing that quietly adds three weeks: the invoice goes to the site contact who booked the work, who is not the person who pays invoices, and it sits in their inbox until somebody asks.

Find out who handles payment at the point of quoting, get their email, and find out whether they need a purchase order number on the invoice. An invoice without a required PO number is not late — it is invisible.

Make the invoice impossible to query

A customer who is not sure what they are looking at does not ring to ask. They put it aside.

The address the work was done at, the date, what was done in words a normal person understands, the parts, the total, the due date, and an obvious way to pay. Photos of the finished work attached to the job help more than people expect, particularly for anything that is now behind a wall.

Chase on a schedule rather than when you are annoyed

Most shops chase at the point of irritation, which is usually too late and never friendly. A fixed rhythm works better and feels like process rather than conflict: a reminder a few days before it is due, one on the day, one a week later, then a phone call.

The phone call matters. An email that has been ignored three times will be ignored a fourth time; a short, polite call is almost always what actually resolves it.

Notice the pattern before it costs you again

Slow payers are usually slow every time, and good shops know who they are. If somebody has been late three jobs running, the fix is not to chase harder — it is to change the terms for that customer. Deposit up front, or payment on completion before you leave.

That conversation is uncomfortable exactly once, and it is cheaper than the fourth late payment.
