The gap between finishing and getting paid

My first year out on my own I had a March that looked great and an April that felt like a mistake. Three projects wrapped, three invoices sent, and a balance that barely moved for six weeks. Nothing had gone wrong. That was the part it took me a while to understand.

You finish the work in March. You invoice at the end of the month because that is when you do admin. Terms say Net 30. The client’s finance team runs payments on the 15th, and yours misses the cutoff by two days. The money lands in May. Your calendar says you had a strong quarter and your account says you are having a thin one, and both of them are telling the truth.

Measure the gap before you try to close it

Most of us know our rate and our revenue. Almost nobody knows their days to cash, which is the number that decides whether a good month actually feels like one. Pull your last ten invoices and write down three dates for each: the day you finished the work, the day you sent the invoice, and the day the money arrived. Two numbers fall out of that. How long you sat on the invoice, and how long the client sat on it.

Use the median rather than the average. One client who took 90 days drags an average somewhere useless, while the median tells you what a normal invoice does. The first time I ran mine, my terms said Net 30 and my median came out at 52 days. Twenty-two of those days were my own doing, because I was batching invoices to month end out of habit, sometimes three weeks after the work had shipped.

Your payment terms are a hope. Your days to cash is the fact.

Most of the gap closes at the front, not at the end

Chasing is the worst place to fix this, because by the time you are chasing, the money is already late and you are negotiating from behind. Nearly everything that decides how fast you get paid happens before the work starts, while the goodwill is fresh and you still have something the client wants.

• Take a deposit and do not start until it clears. A third to a half is normal, and it quietly filters out the clients who were never going to pay.
• Bill on milestones instead of on completion. Three payments across a project keeps money moving while the work is still in flight.
• Invoice the day a milestone lands, not at month end. That one habit took three weeks out of my own cycle and cost nothing.
• Get the name and email of whoever actually pays, at kickoff. The person you talk to every day is often not the person in the approval queue.
• Make paying frictionless. A link they can click beats bank details somebody has to retype into a system you cannot see.

Size the buffer in weeks, not in vibes

“Keep three to six months of expenses” is advice written for people with salaries. What you need is a buffer tied to the delay your own business actually runs on. Add up your fixed monthly costs, the ones that arrive whether or not you work: rent, software, insurance, the groceries you would still be buying in a bad month. Multiply that by your days to cash divided by 30. That covers the ordinary wait. Then add one more month for the client who goes quiet.

Say your fixed costs are $3,000 a month and your median is 50 days. 50 over 30 is 1.7, so $5,000 covers the normal lag and $8,000 covers the normal lag plus one unpleasant surprise. That is a target you can work toward this quarter, which matters more than it sounds: a number you can actually hit beats a number you avoid looking at.

When it is late, be boring about it

A late invoice is rarely a refusal. Usually it is sitting in an inbox that is not the one you sent it to, or in an approval queue nobody mentioned. Treat it as logistics rather than conflict and you get paid faster and keep the client, which is the whole game.

I run the same three touches every time. The day after it is due, a short note on the original thread with the invoice attached again and the pay link. A week later, a reply asking whether it made it into their next payment run, which invites an answer instead of an apology. A week after that, same thread, copying whoever signs off, still factual. Escalating your tone almost never moves an invoice. Escalating to the right person almost always does.

Late fees belong in the agreement or nowhere. If they are in there, mention them once, quietly, and not before the second touch. If they are not, do not invent them in a moment of frustration, because you will spend more goodwill than you collect.

None of this turns you into a collections department. It just stops the money being weather that happens to you. You will still have thin months, because that is the trade you took when you went independent. The difference is that you will see them coming about eight weeks out, which is exactly enough time to do something about it.
