"Let's keep it verbal, I'll write everything to you in the messenger," — you hear from the client, and it seems simpler that way: no need to waste time on paperwork, meetings, or signing. You treat the receipt in the tax app as a formality for the tax authority. And then the client disappears with the money, or demands a refund of the advance, or the tax authority disallows the deduction for the client company — and it turns out you have almost no evidence.
Under civil law, a contract can be concluded through correspondence, but to recover a debt through court, you need agreed terms: subject matter, price, deadlines. Without them, the court may deem the contract not concluded. And a receipt is not only tax reporting but also confirmation of payment and service delivery. Let's go through three real scenarios, a minimal seven-point contract template, and what to do if the documents are already missing.
Scenario 1: The client doesn't pay
You're a freelance designer, you agreed with a client to develop a logo for about $300. You discussed everything in a messenger: he sent examples, you sent a mockup, he wrote "great, I'll take it." You issued an invoice, he said "I'll pay in a few days." Two months passed, the money didn't arrive, and he responds to messages less and less.
What do you have? A chat with no price, no deadlines, no obligations. You didn't issue a receipt because there was no payment. In court, the defendant will say: "We didn't conclude anything, he just sent a picture." The judge will look: the subject matter is undefined, the price is not agreed — and will dismiss the case. Even if you win, you'll have to take the enforcement order to the bailiffs, and the debtor may have no assets.
What you should have done: before starting work, send the client a simple contract (a PDF is fine) with seven points. A signed contract + chat + receipt = almost guaranteed recovery. If the client refuses to sign — that's a red flag.
Scenario 2: The client demands a refund
You're a repair specialist, you took a 50% advance for a cabinet, but delayed the delivery of materials. The client demands a refund and threatens court. You're sure you're right: he himself dragged out the choice of hardware. But the chat has no deadlines or conditions for refunding the advance. The client goes to court and recovers not only the advance but also interest for the use of someone else's money, and if you're a sole proprietor or self-employed — also a fine under consumer protection law (although self-employed individuals don't always fall under it, courts interpret it differently).
What to do: specify in the contract the procedure for changing deadlines, liability for delay, and conditions for refunding the advance. For example: "If material delivery is delayed due to the client's fault, the deadline is shifted proportionally." This is not a panacea, but it reduces risks.
Scenario 3: The tax authority disallows the deduction for a corporate client
You're self-employed, providing services to a company. The company pays you about $1,000 and wants to account for the expenses. But you didn't issue a receipt — you forgot or decided to do it "later." During an audit, the tax authority disallows these expenses, assesses additional profit tax and a fine. The company then comes to you with a claim: "You ruined our deduction." It could go to court, and you'll have to compensate for the losses.
A receipt in the tax app is not just a slip; it's a document confirming the fact of service delivery and its cost. Without a receipt, the client cannot claim the expenses. Moreover, a receipt must be generated for each payment, even if it came in cash.
Minimal 7-point contract template
To avoid spending money on a lawyer, you can draft a simple service contract. The main thing is to include seven points:
- Subject matter — what exactly you do (specifically, not "provision of design services").
- Deadlines — start and end dates, stages.
- Price — total amount and payment procedure (advance, post-payment).
- Acceptance procedure — how the client accepts the work, within what period they sign the act.
- Liability of the parties — what happens in case of delay, late payment.
- Procedure for amendment and termination — how conditions can be changed or the contract terminated.
- Details and signatures — passport data, tax ID, address.
This is sufficient for court. The contract can be drawn up in two copies and signed in person or exchanged as scans by email — this is permissible under civil law. But if the amount is large, it's better to have it notarized or use an electronic signature.
How to issue a receipt and not lose money
A receipt is generated in the tax app or through a bank. Important nuances:
- For each payment — a separate receipt, even if paid in installments.
- On the day of payment — if the money arrived on a card, the receipt must be issued no later than the 9th of the following month? No, by law the receipt is generated at the time of settlement, but if payment is non-cash, it's allowed during the day. In practice, it's better on the same day.
- Indicate the purpose in the receipt — "Logo development under contract No. 5 dated 10.01.2026." This links the receipt to the contract.
- Keep receipts — they will be needed to confirm income and in case of disputes.
If you work through service marketplaces, the receipt may be generated automatically, but check.
What to do if the documents are already missing
Situation: you worked without a contract, didn't issue a receipt, the client doesn't pay. There are chances, but you need to act wisely.
- Collect all correspondence — not only in the messenger but also in email. Take screenshots with visible dates and names.
- Find any confirmations — if you sent files, save delivery notifications; if you met, recall witnesses.
- Send a claim — an official letter demanding payment. This is a mandatory pre-trial procedure for amounts over about $1,000? No, for recovering a debt under a service contract, pre-trial procedure is not mandatory, but a claim often speeds up the process.
- Go to court — if the amount is up to about $500, you can go to a small claims court; if more — to a district court. The state fee is calculated based on the claim amount.
Even if there is no contract, the court may recognize the relationship as contractual based on correspondence, but this is more complex and lengthy. It's better to be safe beforehand.
How an AI twin takes away the routine
Collecting correspondence from different messengers, finding all receipts in email, calculating the debt amount with interest, preparing a claim — this is manual work that takes hours. An AI twin on asibiont.com can automate part of the steps.
For example, you give access to email and documents. The AI finds all emails with the client, extracts the terms (amount, deadlines), generates a debt calculation with interest, and prepares a draft claim. You review, edit, send. The AI won't go to court — that's human work. But it will remind you of the deadline for responding to the claim, collect all receipts into one PDF, and suggest what other documents are needed.
If you work with legal entities, the AI can check whether all receipts have been generated for the current month and remind you of forgotten ones. This doesn't replace an accountant but reduces the risk of fines.
Bottom line
A written contract and a receipt are not bureaucracy but your insurance. You spend 15 minutes drafting a simple contract but gain protection in court and client trust. If documents are missing, collect correspondence, send a claim, and be prepared for court. An AI twin can speed up the preparation of documents and calculations, but the decision is yours.
Start small: download a contract template, issue a receipt for the last service, check that all documents are in order. And if you want to automate the routine — try asibiont.com: the AI twin will collect correspondence, prepare a claim, and remind you of deadlines.
