Example input

[Your business and stage]: Saguaro Suds Mobile Grooming, Phoenix, Arizona (North Central Phoenix, Arcadia and Biltmore areas). I'm the owner and only groomer: 8 years grooming at a salon chain, the last 3 as lead groomer, and certified in pet first aid. For the last 3 months I've groomed part-time from a rented, already-converted grooming van on Fridays, Saturdays and Sundays, while still working 3 days a week at the salon. I want to go full-time with my own van. The business is a single-member LLC registered 4 months ago. Customers book online and I bring the van to their driveway, so the dog never waits in a kennel. Services: full groom, bath and tidy, nail trims, add-ons (teeth, de-shedding). I plan to hire a part-time bather once I'm fully booked.

[Your numbers]: Prices: small dog full groom $75, medium $90, large $110; bath and tidy $60; add-ons $10 to $20. Average ticket so far: $86. Sales: Month 1: 38 grooms, $3,240. Month 2: 52 grooms, $4,470. Month 3: 65 grooms, $5,610. 61% of Month 1 clients have rebooked on a 4 to 8 week cycle. Costs per groom: shampoo and supplies $6, fuel and generator $9, card fees about 3% of the ticket. Monthly costs now: van rental $650 (ends when I buy my own), commercial auto and liability insurance $210, booking software $45, phone $60, marketing $300, water and waste disposal $40. After buying the van: insurance goes to about $320 a month (quote), plus a maintenance reserve I'd set at $250 a month. Capacity full-time: 5 days a week, up to 6 dogs a day. I want to pay myself $3,500 a month once full-time. My own savings going in: $8,000.

[Market and competitor research]: I found 4 other mobile groomers advertising in my area: Groomer A charges $95 to $140 and is booked 3 weeks out; Groomer B $90 to $130; Groomer C $110 and up, mostly large breeds; D is a franchise van at $99 and up. Salons near me charge $60 to $90, but customers wait 3 to 4 hours for pickup. Of my 65 clients, about 70% are dual-income households, many with doodles or older dogs that get stressed at salons. 22 clients came from my Nextdoor posts, 18 from referrals, 15 from Google and 10 from Instagram. I don't have figures for how many dog owners live in my area.

[Funding you want and who reads the plan]: I'm applying for a $45,000 SBA microloan through a local nonprofit intermediary lender. The loan officer said rates run around 10.5% and terms up to 6 years. I'd add my $8,000 savings. Use of funds: a used grooming van, already converted, dealer quote $41,500; second clipper set and a high-velocity dryer $3,300; van wrap and signage $2,700; insurance deposit and city and county licenses $1,500; working capital $4,000. The plan goes to the loan officer and then the lender's credit committee.

Example output

Saguaro Suds Mobile Grooming LLC: Business Plan

1. Executive Summary

Saguaro Suds Mobile Grooming LLC requests a $45,000 SBA microloan to buy its own used, already-converted grooming van and move from part-time to full-time operation. The owner adds $8,000 of personal savings, for total funding of $53,000:

van: $41,500
second clipper set and high-velocity dryer: $3,300
van wrap and signage: $2,700
insurance deposit and licenses: $1,500
working capital: $4,000

At about 10.5% over 6 years, the rate and term the loan officer indicated (both to be confirmed), the payment is about $845 a month. Grooming revenue repays it. In the Year 1 projection, the cash left after all costs and the owner's $3,500 monthly pay covers the payment 2.8 times.

The company is a single-member LLC serving North Central Phoenix, Arcadia and Biltmore. The owner is its only groomer, with 8 years of salon grooming experience, the last 3 as lead groomer. The company has worked three days a week from a rented van for three months. In that time it grew from 38 to 65 grooms a month ($3,240 to $5,610) at an average ticket of $86, and 61% of Month 1 clients have rebooked.

Full-time capacity is 130 grooms a month. The plan assumes 104 grooms a month (80% of capacity) from Month 3, which gives Year 1 revenue of $103,974. Break-even after owner pay and the loan payment is 79 grooms a month. With sales 20% lower, the payment is still covered 1.17 times.

2. Company and Services

Saguaro Suds Mobile Grooming LLC is a single-member Arizona LLC registered four months ago. Clients book online, and the groomer brings a fully equipped van to the client's driveway. The dog is groomed one-on-one and never waits in a kennel.

Services and prices:

full groom: $75 for a small dog, $90 for medium, $110 for large
bath and tidy: $60
nail trims
add-ons such as teeth cleaning and de-shedding, $10 to $20

The average ticket over the first three months was $86. The calculation is $13,320 in sales ÷ 155 grooms = $85.94.

The business is in transition. For three months the owner has groomed Friday to Sunday from a rented van while working three days a week at a salon. With this loan, the owner leaves the salon, buys a van and works five days a week [add: planned full-time start date].

Claude Opus 5.5

This prompt writes a full business plan for a loan or an investor. Paste your business, numbers, research and funding ask; you get every section in lender order, monthly projections and what the lender will still want.

What you get

Every section a lender expects, from the executive summary to the funding request
A financial plan built from your real sales: assumptions, sources and uses, 12 months by month and a downside case
The loan payment checked against your cash flow, with the arithmetic shown
A checklist of what the lender will still ask for, and every gap to fill

How to use it

1
Paste your real numbers
Include sales by month, cost per sale, monthly costs, startup costs and the money you are putting in. The plan is only as strong as these figures.
2
Read the financial plan first
Check the assumptions table and the loan payment against your cash flow before the prose. Correct any assumption that does not match your business and run it again.
3
Fill the gaps, then get a review
Fill every [add] item, collect the documents on the checklist, and have an accountant or small business adviser check the numbers before you submit.

Better results

Paste sales by month, not a yearly total. The projection, the break-even and the downside case all start from your real trend.
Send this follow-up: "Rebuild the 12-month table with sales 30 percent lower and tell me the month cash runs out." Lenders ask exactly that.
Ask your lender for their own checklist and paste it in. The plan will then answer their questions in their order.

Questions

Can ChatGPT write a business plan?

Yes, ChatGPT or Claude can write a complete business plan when you give it your real numbers, customers, competitors and funding ask. Without them it fills the plan with generic claims and invented figures, which a lender spots at once. This prompt marks each missing figure for you to fill instead.

Will a bank accept a business plan written with AI?

A lender judges what the plan says, not who typed it. Every number has to be true and every assumption one you can defend in the meeting. Treat the AI draft as a start, fill the gaps and have an accountant check the financials. No plan guarantees approval.

What do lenders look for in a business plan?

Lenders look first at whether the cash flow can repay the loan, then at how much of your own money is in, your experience, collateral and how realistic your assumptions are. This prompt sets the loan payment against projected cash and lists what the lender will still ask for.

What is the best AI for a business plan?

Any capable chat assistant, such as Claude, ChatGPT or Gemini, writes a solid business plan from good inputs. Business plan apps such as Upmetrics or Venturekit add forecasting templates and formatting. Whichever you use, the figures you paste matter more than the tool.
