The voicemail is calm, which somehow makes it worse. "Hey, it's Karen from the Birchwood job. The tile in the shower niche… it's not what we picked. Can you call me back?"
You know the job. You know the niche. And somewhere in your gut you already know she is probably right, because you remember the supplier substituting a batch and the light being bad the day it went in.
What happens over the next 48 hours will determine two things: what this mistake costs you, and whether Karen ever hires you again or tells her street about you. Contractors get the first part roughly right and butcher the second. It usually happens because they treat "making it right" as a single move when it is actually a choice among three very different tools, followed by paperwork that most people skip.
Three tools, not one
When work falls short, or a client believes it has, you have exactly three honest options. They are not interchangeable.
Redo the work. You return and fix it at your cost. This is the default for genuine defects in your own workmanship: the thing you sold was a correctly done job, and a redo delivers it. It is usually the cheapest option in real dollars, because your cost is labor and materials at your rates, while a refund is priced at retail. It is also the only option that ends with the client owning a correct result, which is what they actually wanted.
Credit against future work or the remaining balance. You reduce what the client owes, now or later, by an agreed amount. Credits fit the middle cases: the work is functional but imperfect in a way not worth tearing out, or the miss is partly subjective, or a redo would be more disruptive than the client wants to endure. A $400 credit on a $12,000 job often resolves a dispute a redo would have prolonged.
Refund money already paid. You send money back. This is the strongest medicine and the rarest correctly used. Refunds fit when the work cannot or should not be redone by you: the relationship is beyond repair, the client is entitled to walk, or you were paid for something that is not going to happen. That last case is a canceled job with a deposit on it, an invoicing error, a double payment. A refund ends the transaction. That finality is its purpose, and its cost.
The decision usually comes down to two questions: Can I actually deliver a correct result, and does the client still want me in their house? Yes and yes, redo. Yes and no, or no and yes, credit. No and no, refund, gracefully and fast.
One more distinction worth respecting: a make-good you offer is goodwill; a make-good the client extracts after a fight is a settlement. The first buys loyalty. The second buys silence, at best. The economics of the two are identical; the outcomes are not. Speed is what separates them. The same $400, offered on Tuesday, is generosity; conceded in week three, it is a defeat both sides remember.
"You're right, that's not the tile you picked. Here's what I'd like to do: we'll swap the niche next Thursday, no charge, about half a day of work. Or if you'd rather not have us back in there, I'll credit you $400 against the final invoice. Your call."
Notice the shape: agree with what is true, offer a concrete fix with a date, give one alternative, let them choose. Clients who are given a choice argue far less than clients who are given a verdict.
The job profitability calculator shows whether a finished job made the profit you priced it to make.
Document the resolution like it was a job
Here is the part almost everyone skips. The dispute gets resolved on the phone, everyone exhales, the redo happens or the money moves, and nothing is written down. Six months later the same client, or their memory, or your own, has a different version of what was agreed.
Every resolution, however friendly, gets written down with four elements:
- What the issue was, in neutral language. "Niche tile did not match selection," not "client unhappy."
- What was agreed. Redo on a date, credit of a stated amount, refund of a stated amount.
- What it settles. The specific issue, so a goodwill credit on the tile does not later get stretched to cover the grout, the paint, and a discount on the next job.
- Confirmation from the client. A reply to a message that lays it out is enough. "Sounds good" under a written summary is worth more than an hour of remembered conversation.
If you resolve it with a redo, treat the redo as real work: schedule it, note the hours and materials, photograph the result. Not to bill it, but because a make-good that costs you $600 should exist in your job costing. Warranty and redo work is a real cost of doing business. If it never gets recorded, your job profitability numbers are quietly lying to you about which kinds of work, and which mistakes, are eating your margin.
Timing matters as much as the writing. Resolve fast, document immediately, and then follow up once after the fix. That last step is what separates the professionals. A two-line message a week after the redo: "Checking the niche is still sitting right and you're happy with it." It costs nothing, it catches the rare fix that did not hold before it becomes a second complaint, and it converts the client's memory of the job from "there was a problem" to "there was a problem and they were all over it." Clients forgive defects readily; what they do not forgive is having to chase you about them. The contractor who resolves a miss quickly and checks back voluntarily routinely ends up with a stronger relationship than if the job had gone perfectly. The client has now seen how you behave when something goes wrong, which is the thing they could never know from a clean job.
And if you absorb something purely as goodwill, record that too, at zero dollars. A written "$0, replaced the cracked switch plate while on site, no charge" does two jobs. The client sees they received something, and your file shows a pattern of you taking care of them, which is exactly the history you want visible if a bigger dispute ever lands.
Never edit history: corrections are reversing entries
Now the bookkeeping, because this is where well-meaning contractors corrupt their own records.
The instinct, when a refund or credit happens, is to go back and change the paperwork so it looks like the final outcome was the plan all along. Shrink the old invoice. Delete the payment and re-enter a smaller one. Make the file tidy.
Do not do this. Ever. The rule that every accountant, auditor and court works by is simple: you never change what happened; you add a new entry that corrects it.
- A refund is not a deleted payment. It is a new, dated entry: money out, linked to the original payment, with a reason.
- A credit is not a shrunken invoice. The original invoice stands as issued; the credit is its own dated record, applied against the balance.
- Even a genuine invoicing error is fixed by issuing a correction, not by silently rewriting the sent invoice. The client has the original, and the moment your copy and their copy disagree, every document you have ever produced becomes negotiable.
This is called an append-only record: entries are only ever added, never altered, and corrections are reversing entries that cancel out the original while leaving both visible. It sounds like bureaucracy until the day it saves you. A client claims they never got the refund: there is the dated entry. Your GST/HST filing is questioned on a credited sale: the invoice, the credit, and the tax adjustment all line up, each with its date. Sales tax on refunds and credits has its own adjustment rules that vary by country and province or state, which is a real reason to keep the trail clean, and a real moment to confirm the details with your accountant.
Edited history, by contrast, has no defense. A record that can be quietly changed proves nothing, including the times it is telling the truth.
Where Zeus fits
Zeus enforces the good habit at the database level: payment records are append-only, and the server refuses to update or delete one at all. There is still an Edit button, because people mistype $5,000 for $500, but what it actually does is append a reversing entry for the old amount and record a fresh payment for the new one, both dated, both permanent. A refund works the same way: money out, linked to the payment it came from, with a reason. A credit note is its own negative document against the original invoice, which stands as issued. The invoice keeps its history, the balance works itself out, and the audit trail survives every correction. Goodwill has a home too: the work you absorbed goes on the job as a note with its photos, so both the redo and the fact that you ate it are in the record. Six months later, nobody is reconstructing the Birchwood niche from memory.
Frequently asked questions
A client is demanding a refund but I think a redo is fair. Who decides?
Legally it depends on your contract and local consumer law, but practically: offer the redo first, concretely, with a date, because a specific offer to correct your own work is both fair and defensible. If the client refuses to let you correct it, document that offer and their refusal before discussing money. In most jurisdictions a contractor who offered a reasonable remedy is in a far stronger position than one who just said no.
Should the refund go back the way the payment came in?
As a rule, yes: same person, same method where practical, and always with a dated record linking it to the original payment. Refunding cash against a card payment, or paying a different person than the one who paid you, creates exactly the kind of loose end that turns into a dispute or a bookkeeping mystery later.
How do refunds and credits affect the sales tax I collected?
Generally, when you refund or credit part of a sale, the associated GST/HST or sales tax gets adjusted too. The rules and paperwork for that, such as credit notes and adjustment periods, vary by country and by province or state. Keep the original invoice, the credit or refund record, and the dates, and confirm the mechanics with your accountant rather than improvising.
Where is the line between goodwill and being a pushover?
Goodwill is proactive, specific, and bounded: you name the concession, tie it to the issue, and document what it settles. Pushover behavior is reactive and open-ended: unnamed discounts to end uncomfortable conversations, repeated concessions to the same client, remedies that grow each time they are discussed. The paperwork is actually your defense here, because a client with two documented make-goods in the file is a client you can politely say no to with the record in front of you.
