Examples: my client won't pay me. My AI said done, did it? My agent spent too much overnight. One AI needs to hand work to another.

My client is using my work but has not paid for it. What can I do?

They published it, so delivery is not in dispute. Freeze the facts, put the record in front of them, name a date, and stop feeding the job.

My client wants a discount after the work is already done. How do I respond?

Sort the ask first (defect, mismatch, or budget pressure), check the acceptance record, hold the price kindly, and trade only against something real.

My client wants to start work without a contract. How do I protect myself?

Four things a contract actually does, settled in one email: scope, price, acceptance, payment terms. Plus the staged start that caps your risk.

My client went quiet in the middle of a project. How do I restart it or close it out?

The restart ladder: a one-line check-in with the record link, a two-doors email, then a close-out package that gets completed stages paid.

How do I invoice for work a client cancelled halfway through?

Freeze the job, sort the stages into three buckets, and invoice each one against its delivery record at the agreed prices.

My client has not approved the final draft. Can I still send the final invoice?

Approval and the invoice run on different clocks. Invoice on delivery, show the pending state on the record, and make deciding one click.

A client owes me for finished work and wants a new project started. Should I start?

Starting doubles the amount at risk and halves your leverage. Three fair doors instead: settle first, deposit plus schedule, or one small paid stage.

How do I ask a client for a deposit before starting work?

The amount, the exact words, and the start gate a deposit creates, plus what to offer when a client says no.

Can I stop work if a client has not paid my last invoice?

Pause early, in writing, with a restart attached. The boring checks first, the record protected before you pause.

How do I end things with a bad client and still get paid for the work I did?

The two-move exit: a final accounting from the delivery record, then a separate closing message. Get paid for the work you did.

My client won't pay me. What do I do?

The full sequence that gets you paid: boring causes first, then the proof packet, then a formal demand with a date on it.

My client is disputing my invoice

Answer the dispute with the record: what was agreed, what ran, and when each step was saved.

My client ghosted me after I delivered the work

Proof of delivery with times attached restarts the conversation from evidence instead of pleading.

What records should I keep in case a client refuses to pay?

The exact set of records to keep from day one, so a refusal meets a file instead of a scramble.

My client keeps questioning what the invoice covers

Document the work as it runs, and the invoice gets a record the client can check line by line.

My client won't pay until they can check the work

Good. Send the packet: the steps that ran, in order, on one page they can check and accept.

How do I prove I delivered the work?

Build the delivery record: each step saved as it ran, with the client's acceptance state on top.

My client says I never delivered the work

Three different claims hide inside that sentence. Each one is settled by a different piece of the record.

My client says they never received my work

Sent, arrived, and opened are different events. The record separates them and shows which ones happened.

What do I send as proof the work is done?

The exact bundle to send: the agreement, the steps, the times, and the acceptance state, in one message.

Prove the work to my client, then get paid

The proof loop pointed at a client: every step leaves a receipt, the client checks it, and payment follows the check.

What is a proof loop?

The check that ends trust me, it is done: steps leave receipts as they run, and anyone can recompute the record.

How do I verify work an AI did?

Claim by claim: what the agent said, what the record shows, and where the two disagree.

How do I prove AI work to a client?

Package the record so a client who was never in the chat can still check every step themselves.

How do I prove my agent actually sent that email?

Sent, drafted, and read are three different claims. The send step's own record settles the one that can be proven, contents included.

Which tool can check whether an AI agent actually did the work?

The one that records each step while the work runs and lets anyone recheck the record afterwards. The three kinds of check, and the one-minute demo test.

Six tests to run on any tool before paying: written at execution time, recheckable by a stranger, independent of the agent, failures visible, honest limits, full export.

A record for every call: model, inputs, saved result, and the commitment a checker recomputes when one call is questioned.

How do I audit my team's AI usage?

Every job leaves a record, so the audit reads the work itself instead of asking each person what their AI did.

How do I audit an agentic workflow?

Rebuild the chain from its receipts: every step, in order, with the gaps named instead of smoothed over.

How do I test my agent for prompt injection?

Drills for the agent and the tools around it: injection in text, in tool outputs, and in tool descriptions, each with its record.

The registry is the name tag; the receipt record is the track record. Identity questions answered from a live registration.

The worksheet: $0 on the free tier, $0.99 for one heavy day, $29 a month for daily client work. No per-receipt fee at any level.

What is the cheapest way to prove AI work to a client?

Let the record write itself while the work runs. Screenshots, self-written certificates, and your own logging all cost more than they prove.

Is there a tool that gives my client a link to check AI work before they pay?

A work diary the record writes for you: every job, every step, none of it reconstructed from memory.

The full sweep: all agents, all sessions, one place to review what ran while you were elsewhere.

My AI agent deleted my files. How do I prove what it did?

Reconstruct the run from the record: every call in order, what each one returned, and the honest limit when the work was never recorded.

My AI said the task was done but nothing actually happened

The five-minute false-done check: name the change the task should have caused, look for its side effect yourself, and compare it with the steps that ran.

My agent spends money while I sleep

Set a hard daily cap on the endpoint the agent already calls. Past the cap, calls are refused with a receipt instead of a charge.

How do I stop my AI agent from overspending?

The cap, the refusal record, and the morning read-back that shows exactly where the money went.

My AI bought the wrong thing. What evidence do I need?

The five-piece pack a merchant or card issuer actually reads: your instruction, the purchase record, the mismatch, your contact log, the money trail.

My agency loses money on delivery calls

Send the proof packet before the call and let the client check the delivery themselves.

Pass the job with its receipts attached, so the next agent starts from a record instead of a summary.

What is the ERC-8004 Validation Registry?

The ERC-8004 registry that asks for proof: a named validator checks a specific job, posts a score, and points at its evidence. Why reputation alone measured 0.14 percent grounded, and why the receipt is what belongs at the evidence link.

What is the AER-1 conformance test?

I have a problem but I do not know which page fits. Where do I start?

Start at the top of this page. Type the problem in your own words and the router takes you to the closest match. If nothing matches, run the free demo instead: it makes one real call and hands you its verifiable receipt, so you can see what a record looks like before you decide anything. Every cluster below is also written in plain words, so browsing works too.

My client won't pay me. Which page solves it?

The won't-pay page in the first cluster. It works the whole sequence in order: check the boring causes first, send a reminder that carries the delivery record, then the proof packet, then a formal demand with a date on it. If your dispute is narrower, this directory has separate pages for a disputed invoice, a client who ghosted after delivery, and a client who says the work never arrived.

My AI said the work is done. How do I check whether it actually did it?

Checking is its own page in this directory: verify AI work. The short version is that a chat message saying done is a claim, not a record. A record shows each step of the job and the time it was saved, and a verifiable receipt proves the saved result was not changed since it was saved. The proof loop page shows how to make that check a habit instead of an argument.

What does it cost to solve one problem today?
