Bookkeeping for window cleaners, from the van

Try MiniCFO.io

Spring and fall are packed: storefront routes in the morning, a two-story house in the afternoon, screens and tracks on Saturday. Then the weather turns, the schedule thins out, and the quarterly tax bill still shows up.

MiniCFO.io is a simple AI financial assistant for mobile service businesses. It keeps the money side quick, so you can get back on the ladder.

Storefront routes in one tap

Set up quick-add templates for your regular work, like a monthly storefront route or a standard two-story house. For a repeat customer, tap Log again. Tag each payment by payment method and filter by it later.

Receipts and route miles

Snap receipts for soap, squeegee rubber, and pole parts when you buy them. The AI pulls out the merchant and amount, and you check them before you log. Add each business drive to the mileage log as you go. It applies the IRS standard mileage rate for the trip's date (72.5¢/mile for trips from Jan 1 to Jun 30, 2026 and 76¢/mile from Jul 1, 2026). Trips are saved in your phone's browser, so log them on the same device.

How much do you actually keep each month?

Revenue isn't profit. Here's the kind of math MiniCFO.io keeps up with for you.

Example (made-up numbers): In October you bill $7,000 (40 house jobs at $175). Soap, squeegee rubber, pole parts, and your phone bill come to $500, so $6,500 is left before taxes. With the simplified method below, that's about $2,619.50 to set aside, leaving about $3,880.50.

This example is a simplified estimate, not tax advice. It uses about 20% for federal income tax, 15.3% for self-employment tax on the full net profit, and a 5% example state rate, the same simplified method as our quarterly tax set-aside calculator. It does not include deductions, credits, other income, your filing status, or the self-employment tax adjustments the IRS uses, so actual tax may be higher or lower. Talk to a tax professional about your situation.

In the app, the tax set-aside estimate card gives you a rough set-aside from your own numbers, shows the next quarterly due date with a countdown, and has a Mark as Paid button. It's an estimate, not tax advice. You can also ask the AI chat something like "What did I keep in September?"

See the winter slowdown coming

The 6-month cash flow projection looks ahead from your own numbers, so a slow December and January don't sneak up on you. Ask the AI chat, or the Live CFO by voice (included in your plan), something like "Can I afford a water-fed pole setup in March?" The weekly summary shows how each week went.
