The Only Free Move You Have
Everything else available to a supplier costs something. Sending the invoice correctly costs nothing and removes most of the delay you can affect.
Yourswho controls this stretch
Sending a correct invoice promptly to the right place is the only move in this collection that costs nothing. There is no counterparty to persuade, no permission required, and nobody who can decline it.
The practical point in “The Only Free Move You Have” is that getting paid depends on records somebody can explain. A small team considering project planning for service teams for project planning can organise time and project evidence before invoicing, with transparent settings, proportionate collection and a visible correction route.
It is also the move most often done carelessly, at the end of a long day, from a template nobody has checked in two years.
The questions raised in “The Only Free Move You Have” can also be checked against Harvest time-and-billing resources. Use the outside resource to identify what evidence and ownership the next action requires.
What "correctly" means
Seven things, none of them difficult:
The right entity. The right order number. Lines that match it. The address that enters the system. The format the portal wants. Inside the cut-off. A description a stranger can recognise.
Two minutes, and they close every gate you control.
Why it is undervalued
Because it is administrative, because it happens after the interesting work, and because the consequences of getting it wrong arrive a month later and look like somebody else's fault.
The template nobody checks
Most small suppliers built an invoice template once and have not looked at it since. Meanwhile customers have changed entity names, added references and introduced portals.
Reviewing it once a year takes twenty minutes.
The checklist
Taped to the process rather than held in memory. Eight items, ticked before sending.
Checklists feel excessive for something done weekly, which is exactly why the errors are in weekly tasks.
The day you send it
The day the work is delivered, within the cut-off, not at month end with everything else.
Costs nothing. Routinely worth two to four weeks.
The confirmation
A week later, one question to accounts payable: received and matched?
Also free, and it converts silent rejection into a same-week correction.
What this does to the rest
A supplier who does all of the above and is still waiting at sixty days knows the delay is entirely on the buyer's side.
That certainty matters: it tells you which conversation to have, and it makes any escalation plainly reasonable.
What it does for your contact
Gives them an invoice they can defend internally without asking you anything.
The easier your document is to push through, the more likely somebody pushes it.
The supplier who does none of it
Sends late, to the wrong place, without the reference, and then chases at day forty-five.
They are not being treated badly. They have spent the free move and are now spending expensive ones.
What it cannot fix
Approval chains, payment runs, absent approvers, a buyer with no cash. None of that is yours.
The point of the free move is to leave only those causes, rather than adding your own.
Why this is the only move that is free
Every other lever in this collection is paid for in something. A deposit costs a negotiation; stopping costs the job; escalation costs the relationship; interest costs the next order; recovery costs a share of the debt. This one is paid for in two minutes of attention.
That makes it the one item here worth getting to a standard of reliability close to total. A supplier who is inconsistent about this has given away the only thing it was holding, and will spend the rest of the year using expensive levers to recover days that were free.
What it does to every later conversation
A correct invoice changes the ground you are standing on when anything goes wrong.
If the payment is late and the invoice was right, the delay is unambiguously inside the buyer, and every question you ask is a question about their process. If the invoice was wrong, every conversation starts with your error, the chase becomes an apology, and the buyer's own lateness is never examined.
This is also what makes escalation and formal steps possible later. A demand, a claim, or a case handed to an agent all rest on a clean document trail, and a supplier whose invoices were resubmitted twice has a file that invites argument.
None of which requires perfection. It requires a short check performed every time rather than most of the time, because the invoices that go wrong are reliably the ones sent in a hurry at the end of a month when nobody checked anything.
The invoice sent the same day
Of everything on the checklist, the date of sending moves the most and is thought about the least.
An invoice raised the day the work finishes rather than at the end of the month gains, on average, a fortnight. Across a year of monthly jobs that is a material change in working capital, obtained without a negotiation, a term change or a single awkward conversation.
It requires only that invoicing stops being a monthly administrative session and becomes part of finishing a job.
The sentence to keep
If the invoice is late, it should be because of something inside their building, and never because of anything inside yours.
