It's the last week of March. You're digging through your phone for receipts, trying to remember which card you used for that supply run back in October. You finally place it, and now you get to piece together what you actually made last year from Venmo notifications and gut feel. Sound familiar?

‍

The problem isn't that you're disorganized. It's that most expense trackers were built for a business with a bookkeeper, and you don't have one. You are the bookkeeper. You're also the scheduler, the invoicer, and the person doing the actual work.

‍

So before you start comparing feature lists, it helps to get clear on what actually matters when the whole business is you.

‍

Five things that actually matter

1. Bank sync that runs without you. Manual entry doesn't survive a busy week. If tracking depends on you remembering to log things, you'll be behind by month two. The connection needs to pull transactions in on its own, permanently, so a packed stretch of work never leaves a hole in your records.

‍

2. Receipt capture on the spot. The supply run. The gas station. The hardware store on the way to a job. Paper receipts disappear somewhere between the counter and your truck. Scanning one on-site takes seconds. Reconstructing it in April takes hours, and you'll still miss some.

‍

3. Categorization that gets easier over time. Sorting business from personal is the real daily work of expense tracking. A tool that makes you classify every transaction from scratch forever is a tool you'll quietly stop opening. It should learn what you spend money on and start handling it for you.

‍

4. A live view of income against costs. Knowing what came in is half the picture. Most solo operators can tell you their revenue but not their take-home. A real-time P&L closes that gap. Not at quarter end. Right now, when you’re deciding whether a client is still worth the drive.

‍

5. It has to live where the rest of your business lives. This is the one most comparisons skip. If your expense tracker sits apart from your invoicing and scheduling, you're entering the same job twice and reconciling two systems that don't communicate. For a one-person business, that's the difference between a tool you use and a tool you meant to use.

‍

What doesn't matter

‍

‍

‍

Knowing what to ignore saves you money. Double-entry ledgers, multi-entity consolidation, inventory management, accounts payable workflows, purchase orders, multi-user permissions. These are real features solving real problems for businesses with staff. None of them are your problem. Paying for them means paying to navigate around complexity every time you open the app.

‍

How the common options stack up

The spreadsheet. Free, flexible, and fine at ten transactions a month. It breaks down because it's static. It won't pull anything in, won't flag what you missed, and won't tell you anything you didn't already type into it. Every hour it costs you is an hour you weren't earning.

‍

QuickBooks Solopreneur. $20 per month, and the replacement for QuickBooks Self-Employed. It's built specifically for Schedule C filers, and the automatic mileage tracking is genuinely good. If you drive a lot and your main goal is maximizing deductions, that's a real advantage worth weighing. The handoff into TurboTax at tax time is smooth. What it doesn't do is run your business. No scheduling, no booking link, no meaningful client records, no way to collect payment at the job site. It tracks the money. It doesn't help you make more of it.

‍

Zoho Books. Free for businesses under $50,000 in annual revenue, then $20 per month for Standard, scaling to $275 for the top tier. The free plan is genuinely generous and it's a capable, full accounting platform. But it's built for a broad audience, and that shows in the interface: modules, ledgers, and reconciliation workflows that assume some bookkeeping familiarity. Transactions import fine. Matching and categorizing them becomes its own project. It's accounting software an operator can use, not a tool shaped around how you actually work.

‍

Solo Pro. Built for independent service operators specifically. Connect up to two bank accounts through Plaid and every transaction pulls in automatically from that point on. No imports. No manual entry. Scan a receipt on-site and Solo Pro reads it before you’ve left the driveway. It learns from your behavior, so classification gets more accurate the longer you use it. Spend by category and spend by vendor are broken out clearly, and the P&L view stays current in real time. All of it sits alongside your booking link, your scheduling, your invoicing, and your client records, because that’s the same business.

‍

Side-by-side comparison

Here’s how the three tools compare for someone running a one-person service business.

‍

‍

The real difference

Zoho Books and QuickBooks Solopreneur are both good at what they were built for. Zoho Books is accounting software. QuickBooks Solopreneur is a deduction tracker with a tax filing on the other end. Neither was built around a person who books jobs, drives to them, does the work, and invoices from the truck.

‍

That’s the gap Solo Pro fills. Your expenses track themselves in the same place your calendar and your invoices live, so at tax time everything is already logged, categorized, and tied to the right period. You hand your accountant a clean picture instead of a pile of questions.

‍

Solo Pro is $30 per month flat, with no add-on fees to unlock features. Every part of the expense tracking is there from day one. If you need multi-entity reporting, inventory management, or a broader accounting ecosystem, Zoho Books is worth evaluating. If you’re running a service business on your own and you want your numbers to build themselves while you focus on the work, Solo Pro is built for exactly that.

‍

Stop guessing at tax time. Start your 7-day free trial and see what it looks like when your numbers are always current.

Frequently Asked Questions

What is the best expense tracker for self-employed workers?

It depends on what you need it to do. If you only want to track deductions and file a Schedule C, QuickBooks Solopreneur at $20 per month covers that well, especially if you put a lot of miles on your vehicle. If you run a service business and need booking, invoicing, and payment collection living in the same place as your expenses, Solo Pro is built for that at $30 per month flat.

‍

Do I need full accounting software if I work for myself?

Usually not. Double-entry ledgers, inventory management, accounts payable, and multi-user permissions solve problems that businesses with employees have. A one-person service business needs four things: bank sync, receipt capture, clean categorization, and a clear view of income against costs.

‍

Is a free expense tracker good enough?

It can be, if your volume is low and you don’t mind categorizing yourself. Zoho Books offers a free plan for businesses under $50,000 in annual revenue. The tradeoff is time. Free tools tend to need more manual upkeep, and the hours you spend on that are hours you’re not earning.

‍

How many bank accounts can I connect to Solo Pro?

Solo Pro connects up to two bank accounts through Plaid. Once they’re connected, every transaction pulls in automatically from that point forward. No imports, no manual entry, and no re-linking every few weeks.
