A law firm partner who demanded we cut our invoice mid-month because he said so. Six previous IT providers. A lesson about direct debit, self-respect, and why the hardest clients teach you the most important things.
There is a particular type of client who does not negotiate — they dictate.
They do not ask whether a change to the agreement is workable. They inform you that the change is happening. The assumption underneath it is that you need them more than they need you, and that you will accept whatever terms they decide are appropriate because the alternative is losing the account.
I had one of these clients early on. A law firm. Senior partner, significant firm, the kind of engagement that looked good on paper and felt important when we signed it.
It took about four months for the true dynamic to reveal itself.
The Invoice That Came Back Red
The first sign was a payment dispute over an invoice we had raised for out-of-scope work. Legitimate work, documented and signed off at the time, billed at the agreed rate. The partner called me — not to query it, not to ask for clarification — to tell me that they would not be paying that portion and that we should reissue the invoice without it.
Not a question. A statement.
I pushed back. I walked through the documentation: the request, the approval, the work completed, the agreed rate. His response was roughly this: he was a significant client, the work had been more expensive than expected, and he did not feel the charge was appropriate. He expected us to absorb it.
I reduced the invoice. I should not have, and I knew it at the time. But I was managing the relationship, keeping the peace, protecting the contract. I told myself it was a one-off.
It was not.
The Pattern
Over the following months, a pattern emerged. Invoices would be paid late, or partially, or with informal requests to “review” line items that had previously been agreed. Every commercial conversation had friction. Every scope discussion ended with an expectation that we would find a way to do more for less.
And it was always framed as a favour — as though accepting less than what we were owed was the reasonable, professional thing to do, and pushing back was somehow unseemly.
I started to feel the cumulative effect on the team. The engineers working on that account noticed that it operated differently from others. They sensed — accurately — that it was a relationship where we were not entirely respected. It affected how they felt about the work.
Six Previous Providers
About eight months in, I discovered something I should have found before we signed the contract.
In a conversation with another IT provider in Melbourne — not a competitor, a peer, someone I knew professionally — the law firm’s name came up. Not because I raised it. Because he mentioned it while we were talking about difficult clients. He had worked with them. He had left.
I started asking around quietly. The firm had, by my best count, been through six IT providers in the preceding five years. Six. The reasons varied in the telling — providers who had not met expectations, relationships that had not worked out, service quality issues. But the common thread was impossible to ignore.
Six providers do not all fail simultaneously. The problem travels with the client.
I had signed a contract with a firm that had a documented track record of burning through IT providers, and I had not known it because I had not checked. That was my failure as much as theirs. Due diligence on a prospective client matters. Reputation in a professional services market is traceable if you ask the right people the right questions.
The Direct Debit Revelation
Around the same time, we were having internal conversations about our billing structure. Payment terms of 14 days net were being honoured inconsistently across the client base — not just by the law firm, but by several others. The administrative overhead of chasing invoices was real, and the cash flow uncertainty was affecting how we operated.
A peer MSP who was about twelve months further down the road than us had switched his entire client base to direct debit. He explained it simply: professional services firms — accountants, lawyers, medical practices — almost universally put their own clients on direct debit. They understand the logic. If they push back on being billed the same way, it tells you something.
We made the switch. We moved all new agreements to direct debit from that point, and we transitioned existing clients over renewal. Almost everyone accepted it without comment. A few asked questions and then accepted. The law firm refused.
They did not want to explain why. They did not want to discuss it. They simply declined to authorise the direct debit and indicated that the current arrangement — pay when they decided to pay — was how it would remain.
That refusal was the clearest signal yet. A business that will not accept direct debit is a business that wants to preserve the option to withhold payment as leverage. There is no other reason.
The Conversation I Should Have Had Sooner
I terminated the engagement. I gave them proper notice, helped with transition, and documented everything carefully.
The partner’s reaction was instructive. He was not surprised. He did not attempt to retain us. He moved to his next provider. I later heard, through the same professional network, that the relationship with that provider had also deteriorated within six months.
The lesson was not just about this client. It was about the dynamic I had been accepting — and what accepting it had been costing us.
When you allow a client to underpay you, you have not saved the relationship. You have established the terms on which the relationship operates. You have told them that their leverage works. They will use it again, because it has worked every time before. You will spend the life of that contract absorbing the consequences of having set that precedent in month four.
The same principle applies to scope creep, to disrespect in communication, to any pattern of behaviour that you accommodate because the alternative feels confrontational. Accommodation in the first instance makes the second instance harder to push back on, and the third harder still.
What Changed
We restructured several things after that experience.
Direct debit became non-negotiable for all new clients. Not a preference, not a default that can be negotiated away — a requirement. We explain it plainly: it is how we work, it is how every professional services firm that invoices regularly should work, and it ensures the administrative relationship stays clean so the actual work can get the attention it deserves.
We built explicit contract terms around scope, with a documented approval process for out-of-scope work that requires sign-off before the work is done rather than after. No more invoice disputes over work that was verbally approved.
And we got more rigorous about due diligence before signing new clients. Provider history, referees, industry reputation. Not because we are looking for perfect clients — no such thing — but because we are looking for clients whose history suggests they engage with providers in good faith.
On Saying No
The hardest thing I had to internalise is that saying no to the wrong client is not losing business. It is protecting the business.
Every hour spent managing a client who will not pay, who disputes scope, who treats your team poorly, who drains goodwill and creates friction — that is an hour not spent serving the clients who value what you do, growing relationships that are genuinely productive, and building the business you are actually trying to build.
The law firm was consuming disproportionate energy relative to the revenue. The revenue was not the point — the energy was. Once you account for the time spent on invoice disputes, the stress on the team, the management overhead, and the opportunity cost of not having that capacity available for better relationships, the economics looked completely different from what the contract value suggested.
I do not regret the experience. It taught me things I could not have learned any other way. But I would not repeat it — and I have not, because I now recognise the pattern early enough to make a different choice.
