Ask ChatGPT About Your Exchange Books

Every currency exchange accounting software has dozens of reports: profit and loss, debtors, currency position, cash flow. But the real questions an exchange manager asks are rarely answered by any one of them. "Why was profit lower this month?" has no single report. You have to put two months side by side, see which currency and which customer changed, and then draw a conclusion.

This is exactly what AI does well. Starting today, you can connect your own ChatGPT to your exchange books in Nexto and ask these questions in your own words. In this article we explain what this connection is, which questions are worth asking, and what you need to know about security.

What does connecting ChatGPT to your exchange books mean?

On its own, ChatGPT knows nothing about your exchange. If you ask it "What is so-and-so's balance?", it either guesses or says it doesn't know.

With an MCP connection, ChatGPT gets access to a set of read-only Nexto tools. When you ask a question, it decides which reports to read. For "Are my books healthy?", for example, it reads uncleared receipts, debtors, and currency positions, puts them together, and answers.

MCP is an open standard for connecting AI to software. The same connection works with Claude and Gemini too, but since ChatGPT is the most widely used, the examples in this article use ChatGPT.

Simple question or analytical question?

You don't need ChatGPT for a simple question. Nexto shows "Ahmed's balance?" in a second.

The real value of the connection is in questions that:

have answers spread across several reports;
need comparison or calculation;
or have an answer that is a judgment, not a number.

A real example on the Nexto demo exchange:

Question: Are my exchange books healthy? Tell me where I should be worried.

Answer: Overall I see no serious problem, but three areas need attention:

13 receipts are still uncleared, totaling 14.9 billion toman; the oldest is 28 days old. Match them against your bank statement.

Receivables are concentrated: the 10 largest debtors hold 81% of all receivables, and one partner exchange alone owes $570K.

You are short on euro and tether (about $20K). If the euro rises above 1.1315, closing this short position will cost you.

To get these three lines yourself, you would have had to open four different pages and piece them together.

Questions you can ask

We've grouped this list by category. You don't need to type these exact sentences; ask in your own words.

Book health and control

Are my exchange books healthy? Tell me where I should be worried.
Which receipts have been uncleared for more than a week, and whose are they?
Which documents were deleted or edited after the deadline this month, by whom, and for what reason?
Who changed Ahmed's trade document from yesterday, and what did it say before?
Which user logged in outside working hours?
What open operations are there (payment commitments, deposit requests, cashbox orders), and which ones have gone stale?

Profit and loss

Why was profit lower this month than last month? Break down the cause by currency and customer.
How has profit per currency changed over the past three months? Which currency is declining?
Who are this year's ten most profitable customers, and what share of total profit do they bring?
How much of our profit comes from transfer fees?
How does net profit after expenses this quarter compare with last quarter?

Currency risk and liquidity

Which currencies are we short or long on right now, and what is the break-even rate for each?
If the dollar rises 2%, how much do we gain or lose?
How much is due in cheques next week, and are the cashboxes enough to cover them?
How have the exchange's daily assets trended over the past month?

Customers

Which profitable customers have stopped coming back? When was their last trade?
How concentrated are receivables among a few large debtors? What happens if the largest one pays late?
Which debtors have gone over their credit limit?
How many new customers did we get this month, and how many of them made more than one trade?
How has Ahmed behaved over the past six months? Give me his trading volume, the profit he brought in, and his balance trend.

Management decisions

Based on Turkish lira trades over the past few months, is hiring an employee at a monthly salary of 30,000 lira worth it?
If we raise the transfer fee by half a percent and volume stays the same, how much does monthly profit change?
Which dealer brought in the most profit, and how much commission did they earn?
How many documents did each employee record this month? Is the workload balanced between them?

Ready-made summaries

Give me today's summary for the exchange: trades, profit, cash in and out, and pending tasks.
Compare this month with last month.
Give me Ahmed's PDF statement from the start of last month.

In Claude, these summaries are also available as ready-made prompts in the menu. In ChatGPT, just type the sentence.

A closer look at a few examples

"Is a new hire worth it?"

For this question, ChatGPT reads lira trade profit month by month, takes the average, and compares it with the 30,000 lira salary. The answer looks something like this: "Monthly lira profit is roughly X; this employee's salary would take Y% of it. If this employee raises volume by at least Z%, the hire pays off."

The final decision is yours. But the numbers you need to make it are in front of you within a minute.

"Who deleted this document?"

You can find this answer in the app, but you need to know where to look. ChatGPT tells you directly: document X was deleted on day Y by user Z, for this reason, and whether it was within the deadline.

"Why did profit drop?"

ChatGPT puts the two months side by side and finds the differences. For example, it might say "The number of trades is about the same, but profit per trade in dirham has halved," or "Two large customers didn't trade this month."

Security: you hold the key

The most important point: No data is sent anywhere until you switch it on yourself. The connection is off by default, and the exchange manager turns it on or off with a single checkbox in the assistant settings.

Once it's on:

Read-only: ChatGPT cannot record, edit, or delete documents, or send messages.
Same permissions as the app: Each user sees only what they are allowed to see in Nexto. Hidden accounts, profit without permission, and private notes never leave.
Only for users the manager chooses: The manager decides which users may connect.
Your password never leaves: ChatGPT only receives a short-lived token. All communication is encrypted.
Instant revoke and full log: Any connection can be revoked from the profile, and every data read is recorded in the activity log.

One more thing to be aware of: the conversation stays in the user's own ChatGPT account and is kept according to that account's settings. If you don't want your conversations used for model training, check ChatGPT's privacy settings.

AI makes mistakes too

ChatGPT reads the numbers from your real books, but the analysis and conclusions are its own, and it can get something wrong. So:

For an important decision, check the key number once in Nexto itself.
Ask precise questions: state the time range, currency, and customer name.
If an answer looks odd, ask "Which report did you get this number from?"

In our article The real limits of AI in a currency exchange, we cover in detail where AI helps and where it should not replace people. The same rule applies here: AI analyzes, you decide.

How to connect

The manager turns it on: In the assistant settings, check "Personal AI connection" and grant access to the users who need it.
Copy the address: The connection address is in the "AI connection" card on each user's profile.
Add it in ChatGPT: Add the address as an MCP server, sign in to Nexto, and click "Allow."

Adding a custom MCP server is available on ChatGPT's paid plans. On the Nexto side, this feature is part of the Professional plan and the Lifetime license, and it is enabled in the free demo so you can try it before you buy. More details are on the Connect ChatGPT to Nexto page and in the connection guide.

Summary

Reports tell you "what happened." The real question for an exchange manager is usually "why did it happen" and "what do I do now." Connecting ChatGPT to your exchange books fills that gap: the numbers come from your real books, the AI does the analysis, and the decision stays with you.

Start with "Are my books healthy?" The answer usually shows you something you hadn't seen before.
