Quick answer
Yes, you can use ChatGPT or another assistant to draft a business plan or loan summary, and no lender can promise to spot or ignore it. What matters is whether every figure ties to your bank statements, BAS and financials. Let AI organise and explain your real numbers; never let it invent projections, and never paste in identifying documents.
Key points
- Lenders test your figures against statements and returns; they aren't marking prose style.
- Nobody can reliably promise that AI text is, or isn't, detected, so don't build a plan around either outcome.
- The OAIC says AI output is probabilistic and can be wrong, so a human must verify it.
- Feed the assistant totals you've checked, not statements, logins or customer names.
- A forecast that ties to history and shows its assumptions beats a polished one that doesn't.
An assistant can turn a rough idea into a tidy plan in an afternoon, which is why so many owners now start there. The question isn’t whether that’s allowed. It is. The question is what a lender does with the result.
The short version: a lender reads your plan alongside your bank statements, and any gap between the two is what causes trouble. This guide covers what AI is good for, what it gets wrong, and a routine that keeps the plan honest.
Can I use ChatGPT to write a business plan for a bank loan?
Yes, for the drafting. Not for the facts.
business.gov.au describes a plan as something that helps you prepare when you start and adapt as you grow. It doesn’t prescribe a format that a lender requires, and nothing in it says the words must be hand-typed. An assistant is useful for the parts that are about communication:
- structuring a one-to-three page summary: what you do, who buys, what the money is for, how it’s repaid;
- turning your bullet points into clear paragraphs;
- listing the questions a lender is likely to ask, so you can answer them first;
- spotting jargon, repetition and gaps in the story.
It is poor at the parts that are about truth. It doesn’t know your customers, your margins or your lease, so it fills gaps with plausible-sounding statements. The OAIC says plainly that AI systems “are known to produce inaccurate or false results”, that outputs are probabilistic, and that a human should check them. In a loan application, a plausible invention is a liability.
Will a lender mind that I used AI?
Lenders care whether the content is accurate, consistent and specific. How it was typed isn’t the test.
Search for “can lenders detect AI” and you’ll find vendors claiming red flags in AI-written plans. Treat that as marketing. No one can honestly promise that AI text will be caught, or that it won’t. Building your plan around either guess is a mistake.
What you can control is the thing lenders reliably do check. Most assess what you provide against your own records: typically six to twelve months of business bank statements, plus BAS, returns or financials where the loan size calls for them. A plan that says revenue is “steadily growing fast” when deposits are flat is a problem whether a person or a chatbot wrote the sentence.
What will a lender test the plan against?
Think of five cross-checks. Run them yourself before anyone else does.
| Claim in your plan | What it gets checked against |
|---|---|
| Monthly revenue or growth | Deposits in your bank statements and BAS sales |
| “Strong margins” | Profit in your returns or financials |
| Existing debts | Repayments visible on your statements |
| How long you’ve traded | ABN and bank account history |
| What the money is for | Quotes, invoices, a contract or a clear sizing logic |
If the plan and the records disagree, expect questions. If they agree and you’ve explained the odd months, the plan has done its job.
How do I use AI for cash flow projections without making things up?
Projections are where AI-assisted plans most often go wrong, because an assistant will happily generate a smooth, confident growth curve from nothing.
Business.gov.au points owners to a cash flow forecast template, and a spreadsheet you build yourself is better than a number an assistant produces. Use the assistant as a calculator and a critic, not an author:
- Start with history. Fill in your last twelve months from your own records: deposits, major costs, loan repayments.
- Write your assumptions yourself. “New contract starts March, worth about X a month.” “Prices rise on 1 January.” “Quiet period June to July as in previous years.”
- Let the assistant do the arithmetic and layout. Ask it to build the next twelve months from your history and your stated assumptions only.
- Ask it to challenge you. “Which assumptions here are the weakest, and what would a cautious lender ask about them?”
- Add a downside case. Sales noticeably lower. If repayments still fit, say so. If they don’t, you’ve learned something before the lender has.
- Reconcile. The first months must line up with your latest actual statements.
If you’re borrowing for a specific purpose, such as equipment or stock, attach the quote and show what the purchase adds in revenue or saves in cost. Don’t let the assistant guess that number.
What can I safely give an AI tool?
Less than you think. The OAIC’s best-practice advice is “do not enter personal information, and particularly sensitive information, into publicly available generative AI tools”, and it warns that once information is in, it can be impossible to remove. The ACSC’s small business guidance says the same in practical terms: set rules about what gets shared.
For a plan, you don’t need identifiers. Give it:
- monthly totals (deposits, major cost lines, repayments);
- generic labels (“Customer A”, “landlord”, “equipment lease”);
- your own written assumptions;
- a plain description of the business and the purpose.
Keep out tax file numbers, logins, account numbers, whole statements, and customer or staff names. The full redaction routine is here.
Which prompts actually help?
Specific prompts, grounded in your material, give better results than “write me a business plan”. Try these, swapping in your own totals:
- “Here are my notes about the business and the loan purpose. Turn them into a one-page summary under these headings: what we do, who pays us, what the money is for, how it’s repaid. Don’t add any fact I haven’t given you.”
- “Here are my monthly deposit totals for the last twelve months. Describe the pattern in two sentences, and tell me what a lender might ask about the lowest month.”
- “List the ten questions a lender would most likely ask about this request. I’ll answer them.”
- “Read this draft and mark every claim that isn’t supported by the notes I gave you.”
That last prompt does more for you than any detection fear. It finds the sentences the assistant made up so you can delete them.
What does a sound AI-assisted plan look like? (Illustrative example)
Illustrative only — an invented business and figures.
A commercial cleaning contractor wants finance to buy a second van and take on a new office contract. The owner gives an assistant their notes and twelve monthly deposit totals, with no names, and asks for a one-page summary and a twelve-month projection.
The first draft says revenue “grew rapidly” and projects a smooth rise every single month. The owner checks it against their statements: deposits rose in two steps, when two contracts began, and are otherwise flat. They delete “rapidly”, rebuild the projection from the contract start dates they actually hold, and add a case with the new contract delayed by two months.
They also notice a thin month last winter and add two sentences explaining a client’s late payment. The finished plan is shorter and less impressive-sounding than the draft. Every line can be matched to a statement or a signed contract. That is what a lender is looking for.
What mistakes cost owners the most?
Four come up repeatedly:
- Round, confident projections with no stated assumptions. A lender can’t test a number with no reasoning behind it.
- Growth claims the statements don’t show. Deposits are visible, so a mismatch is obvious.
- Leaving out a weak month. Explaining it takes two sentences; having a lender discover it unexplained costs credibility.
- Pasting in the raw file to save time. It exposes other people’s details and, as the OAIC notes, can’t be taken back.
None of these is about AI. They’re ordinary plan-writing errors that AI makes faster to commit, so the checking step matters more, not less.
What if the lender never asks for a plan?
That’s common. Many unsecured and cash-flow facilities are sized mainly on bank statements and turnover, so the plan is not the main event. A one-page summary still helps: it explains the purpose, covers any unusual month, and shows you’ve thought about repayment. If you’d like the self-check questions first, start with the pre-application questions or try the loan navigator.
If you’d rather check your options now and tidy the plan once you know which route fits, that’s a reasonable order too.
Ready to put your plan in front of a real person?
A good plan makes a conversation easier. It can’t tell you which kind of finance suits your numbers, and an assistant can’t ring you back to talk it through.
That’s what we do. Enquiring takes about a minute, and there’s no credit check when you ask, so your credit file isn’t touched just for exploring. Your details stay with one team rather than being sent to a pile of lenders, so you won’t get a flurry of calls from strangers. A real person reads your situation and phones you. Fill in the form accurately, with figures that match your statements, and the first option we look at is far more likely to be the right one.
Frequently asked questions
Can I use ChatGPT to write a business plan for a loan?
Yes. It's good at structure, plain-English wording and questions you hadn't thought of. The facts and numbers must come from you and be checkable against your records. Treat the draft as a first pass you edit, not a finished document.
Will a bank accept an AI-written business plan?
Lenders assess the business and the numbers behind the plan, not who typed the words. A plan that's accurate, specific and consistent with your statements is accepted on its merits. One with vague claims or figures that contradict your records struggles, however it was written.
Can lenders tell if I used ChatGPT?
Nobody can honestly promise either way. Detection tools are unreliable, and vendors selling them have a commercial interest. The safer assumption is that the lender will check the content against your documents, so make sure it holds up.
Can AI write my cash flow projections?
It can build the layout and do the arithmetic, but it shouldn't choose your assumptions. Start from your actual monthly history, state each assumption yourself (new contracts, price changes, seasonality), and have the assistant only calculate and flag gaps.
What should I never put into ChatGPT for a loan application?
Tax file numbers, banking or ATO logins, account numbers, full statements, and customer or staff names. The OAIC's advice is not to enter personal information, particularly sensitive information, into public AI tools. Use monthly totals and generic labels.
Do I need a business plan to get a business loan?
Not always. Many unsecured and cash-flow loans are sized mainly on bank statements and turnover. A short plan or one-page summary helps most for larger, property-secured or purpose-specific requests, and when your numbers need explaining.
How long should a plan for a loan application be?
Short is fine: one to three pages covering what the business does, what the money is for, how it will be repaid, and an explanation of any unusual months. A lender wants clarity and consistency, not volume.
