Pay
Do not match the price; change the comparison
If the only visible difference is cost, the cheaper listing wins, and correctly.

A buyer looking at two listings that describe the same thing at different prices should pick the cheaper one. That is not irrationality on their part; it is the correct decision given the information you gave them.
So the problem is never that someone is cheaper. The problem is that your listing and theirs are legible as the same product, and the fix is at the description, not the number.
Match the price and you have agreed with them
Cutting to meet an undercut concedes the argument that the two offers are equivalent. It also does four things you cannot easily undo.
It resets your anchor, so every future buyer sees the lower figure as your real price and the old one as aspirational. It also lowers the quality you signal, since buyers read price as evidence: Rao and Monroe's 1989 meta-analysis in the Journal of Marketing Research found a positive, statistically significant relationship between price and perceived quality for consumer products. It invites the next cut, because whoever undercut you once has demonstrated a willingness to do it and usually has a lower cost of time. And it changes your buyer mix toward the most price-sensitive segment, which is also, reliably, the segment that produces the most revisions and the most disputes per pound of revenue.
The mechanics of why the cheapest tier attracts the hardest work are worked through in the piece on the bottom tier, and it is the argument to have in mind before you touch the number.
The four things that make a comparison unequal
Format. Two written assessments are comparable. A written assessment and a written assessment plus a two-minute recorded walkthrough are not, and the second one cannot be priced against the first by anyone.
Specificity of the promise. "Honest feedback" competes on price. "Scored on five named axes, roughly 500 words, with one paragraph per axis, back within 12 hours" does not, because the buyer now knows what they are getting and the cheaper listing has not told them.
Evidence. A public worked example on generic material converts an assertion into a demonstration. Almost nobody builds one, which is why the post on building a public example is the highest-leverage response to an undercut available to you in an afternoon.
Turnaround, stated and met. Speed is one of the very few attributes a buyer can verify objectively, and a guaranteed window is a real product feature rather than a claim.
Each of these moves the buyer's question from "which is cheaper" to "which of these two different things do I want", and that question has no automatic answer.
Where the floor came from
Some undercutting is not another earner at all. Instant automated scoring set the price of generic assessment at approximately zero, and anything in your offer that a model produces in two seconds is priced accordingly no matter who you are competing with. The technical account of what those systems actually do is worth reading once as a map of which parts of your deliverable can never carry a price, and the tools that package it are what most buyers have already tried before they consider paying a person.
That is not bad news, because it also tells you where the defensible ground is: judgement, context, and the fact that a named human being actually looked.
When to concede the segment
Sometimes the honest answer is that the cheaper earner should have that buyer.
If a segment is bounded in price, high in volume, and low in complexity, and someone is willing to serve it at a rate that does not work for your minutes per job, the correct move is to stop describing yourself in terms that attract it. Raise the floor of your own listing, remove the entry-level option, and let the enquiries you were losing anyway stop arriving.
The test is arithmetic rather than pride. Work out your take-home per hour on that segment after fees and unbilled time, compare it to your take-home on everything else, and if the gap is large the segment is a distraction with a revenue line attached. Why the same earner's effective hourly rate swings so widely covers how to compute that honestly, including the parts people leave out.
Conceding a segment deliberately is very different from being pushed out of it. The first leaves you with a smaller, better book; the second leaves you doing the same work for less.
What to say when a buyer names the cheaper price
Do not defend the number and do not disparage the other listing. Restate the difference in one sentence and let them choose.
"That one is a short written note; mine is a scored assessment across five axes with a written justification for each, back within 12 hours" is complete. It is also true, checkable, and does not ask the buyer to take your word about quality, which they have no way to evaluate anyway.
If the honest answer is that there is no difference, that is the finding. Build one, or accept the market price.
If precision itself is your differentiator, the conventions to be exact against are documented on the measurement side rather than something to invent per job - inconsistency there is the fastest way to lose an argument you should have won. And for how listings sit next to each other in practice, including what a buyer sees before they open either one, Rate Cock's judges page is the platform-side reference.
The durable position is not being the cheapest or the best. It is being the only listing on the page that a buyer can describe accurately after closing the tab.
