Best expense tracker for small business owners
The useful question is not which app is best. It is whether your obligations require accounting software or a categorised personal ledger will do.
In short
The short answer
For a sole trader with no employees and no invoicing obligations, a categorised personal ledger with receivables usually covers the job. Once you need to issue invoices, handle sales tax properly, or file structured accounts, that is accounting software and a ledger will not substitute.
How we judged
- Do you need to issue invoices, or only record what you were paid?
- Does your jurisdiction require structured accounts or sales tax returns?
- Do you have employees, or contractors you pay regularly?
- Can business and personal be separated by category and account?
- Is there somewhere to hold costs a client will reimburse?
expenie is our own product, so treat its inclusion accordingly. Every pick below states what it is bad at as well as what it is good at.
The picks
1. Best for invoicing and filing obligations
Dedicated accounting software
If you issue invoices, handle VAT or sales tax, pay employees, or your jurisdiction requires structured accounts, this is not optional. Purpose-built software does a job no personal ledger can, and trying to substitute one is a false economy.
Trade-off: Considerably more complexity and cost than a sole trader with simple obligations needs, and it generally will not help you budget your personal life.
2. Best for a sole trader with simple obligations
expenie
Prefixed business categories give a clean filter at tax time in one workspace, a business card can be its own account, and receivable loans hold costs clients will reimburse so they do not distort two months. Read-only Member access lets an accountant see your books without a shared login.
Trade-off: No invoicing, no double-entry, no VAT or sales tax engine, no payroll, and one currency per workspace. It will not file anything for you.
3. Best for very low volume with unusual arrangements
A spreadsheet with a business tab
For a handful of transactions a month and arrangements no product models, a sheet is free, exact, and yours. Plenty of small operations run entirely this way.
Trade-off: No validation, and if your obligations grow you will be migrating under time pressure at the worst possible moment.
4. Best for high receipt volume
A dedicated receipt-scanning app
If your business generates a lot of paper receipts that need retaining for compliance, a tool built around capture and storage of those documents is doing something a ledger is not designed for.
Trade-off: Solves storage rather than bookkeeping. You still need somewhere the amounts actually go.
The boundary that decides everything
Before comparing tools, work out which side of a line you are on. The answer makes most of the decision for you.
You need accounting software if you issue invoices, handle VAT or sales tax, employ anyone, pay contractors regularly, operate through a company with filing obligations, or your jurisdiction requires structured accounts.
A categorised personal ledger is usually enough if you are a sole trader, get paid without issuing formal invoices or issue very few, have no employees, and mainly need to know what you spent and what you are owed.
Trying to run the first case on a personal ledger is a false economy that surfaces at the worst possible time. Running the second case on full accounting software is paying for complexity you will not use.
Being explicit about what is missing
expenie is a solo personal finance app. It is worth stating the boundaries plainly rather than letting you discover them:
- No invoicing. It records money received; it does not produce documents that request it.
- No double-entry bookkeeping.
- No VAT, GST, or sales tax engine.
- No payroll or contractor management.
- No filing, and nothing formatted for a tax authority.
- One currency per workspace, with no conversion.
If any of those are requirements, stop here and use accounting software. This guide is not going to argue you into the wrong tool.
What a ledger does cover
For a sole trader with simple obligations, the actual daily job is narrower than it sounds.
Categorised business costs with a consistent prefix — Business · Software, Business · Travel, Business · Fees — sitting in the same flat list as your personal categories. They sort together, they are one tap, and searching the prefix gives you the whole set at tax time.
A business card as its own account, so every line carries two signals and a personal spend on the business card is visible rather than buried.
Receivables for costs a client will repay, with a balance that drops on partial settlement — which keeps a reimbursable from making this month look bad and next month look good.
And transfers for paying yourself and for tax set-asides, so those movements do not appear as income or expenses they are not.
Paying yourself is a transfer
This trips people up constantly and is worth being explicit about.
If business income lands in one account and you move a portion to your personal account, that is a transfer. Logging it as income double-counts money you already recorded when the client paid. Logging it as an expense makes the business look unprofitable.
The same applies to a tax set-aside. Moving money into a Tax account is a transfer — it stops being spendable without pretending it was spent. The percentage depends entirely on your jurisdiction, and this is not tax advice; the structural point is that a number you can see beats a number you intend.
Giving your accountant a view
A practical need that most personal tools handle badly: letting someone see your books without handing over your login.
In expenie an owner can invite a Member by email and grant read-only access to specific pages — statement, accounts, insights, budgets, loans, recurring. Members view what you grant and can never mutate anything.
That covers the accountant case without a shared credential and without the coordination overhead of a collaborative tool.
FAQ
- When do I need real accounting software?
- When you issue invoices, handle VAT or sales tax, employ anyone, or your jurisdiction requires structured accounts. A personal ledger will not substitute, and discovering that at filing time is expensive.
- Is paying myself from business income an expense?
- No, it is a transfer between accounts you own. Logging it as income double-counts money recorded when the client paid; logging it as an expense makes the business look unprofitable.
- Can my accountant see my books without my login?
- Yes. An owner can invite a Member with read-only access to specific pages. Members view what you grant and never mutate anything.
