The best accounting software for one person may be a spreadsheet.
A solo business does not need enterprise software in miniature. It needs complete records, monthly reconciliation, understandable reports, and a workflow the owner will actually maintain. Buy software when it removes a specific failure—not when revenue makes the business feel official.
Use a spreadsheet for simple, low-volume, one-account books that close monthly. Choose Wave for the smallest software budget, FreshBooks for client invoicing and time, Xero for full accounting and collaborators, QuickBooks when a U.S. accountant or workflow requires it, and Zoho Books for suite-oriented value.
When a spreadsheet is genuinely enough
A spreadsheet is enough when it behaves like controlled bookkeeping, not a memory aid. It must include every business bank, card, cash, processor, and marketplace transaction; separate gross sales, fees, refunds, and sales tax; preserve receipts; and tie to statements every month.
There is no honest universal transaction threshold. Complexity beats volume. Ten marketplace orders can create sales tax, processor fees, refunds, and reserves; 100 recurring ACH receipts can be almost uniform. Move when exceptions, not rows, exceed your control.
Five software answers for five solo-business shapes
Wave: best for the smallest budget
Wave Starter costs $0 and includes unlimited estimates, invoices, bills, and bookkeeping records. It is the first software to test when manual bank entry is acceptable. Pro costs $19 monthly or $190 annually and adds automated bank imports through Plaid, categorization, receipts, reminders, extra users, and stronger support.
Best for: a solo service owner with simple books. Leave when: feeds, integrations, payables, inventory, or reporting create recurring cleanup.
Review Wave →FreshBooks: best for invoicing-led services
FreshBooks is for a solo professional whose work moves from estimate to time or project to invoice to payment. Lite is $23 monthly for five billable clients; Plus is $43 for 50 and adds proposals, retainers, accountant access, and fuller reports. Premium is $70 and adds unlimited clients and bills/accounts payable.
Best for: consultants, designers, photographers, contractors, and other client-service work. Leave when: client caps, team seats, or missing accounting depth make a fuller ledger cheaper.
Review FreshBooks →Xero: best for a real accounting system with room to collaborate
Xero Early is $25 monthly and includes bank connections, reconciliation, smart document capture, reporting, and unlimited users, but limits invoices to 20 and bills to five. Growing is $55 and removes those limits. Xero also advertises more than 1,000 certified apps.
Best for: an owner adding a bookkeeper, ecommerce, external apps, or stronger financial control. Leave—or skip—when: the accountant requires QuickBooks or Early’s caps make the regular cost disproportionate.
Review Xero →QuickBooks Online: best when other people require it
QuickBooks Simple Start is $38 monthly for one business user plus accountant access. Essentials is $75 for three users and Plus $115 for five. The product’s strongest argument for a solo owner is not features in isolation; it is compatibility with a U.S. accountant, payroll/tax process, lender, or industry integration.
Best for: an owner with a named QBO dependency. Skip when: “industry standard” is the only reason and a less expensive product closes the books just as well.
Review QuickBooks →Zoho Books: best suite value
Zoho Books Free supports one user plus one accountant, up to 1,000 invoices a year, and businesses under its $50,000 revenue threshold. It can reconcile imported statements, but connected bank feeds begin on Standard at $20 monthly or $15 annually. Standard also adds custom reports, API access, and period locking.
Best for: a value-conscious owner using or considering Zoho’s broader suite. Skip when: accountant familiarity or a critical connection makes the cheaper price false economy.
Review Zoho Books →Match the product to the business model
| Solo business | Start here | Why | Watch for |
|---|---|---|---|
| New consultant with 3 clients | Spreadsheet, Wave, or FreshBooks Lite | Simple books; client workflow may be more valuable than ledger depth | FreshBooks five-client cap; payment fees; receipt discipline |
| Freelancer with 20 clients and retainers | FreshBooks Plus | Proposals, retainers, time, invoices, accountant access | 50-client cap and paid team seats |
| Ecommerce seller | Xero Growing or QuickBooks plan matched to integration | Processor, marketplace, inventory, returns, and fees require connected reconciliation | Connector quality, duplicate orders, sales tax, inventory source of truth |
| Local cash-heavy operator | Accountant-approved system; often QuickBooks or Xero | Deposits, petty cash, payroll, and documentation need controls | Software cannot prove unrecorded cash; daily procedure matters |
| Zoho-based agency | Zoho Books Standard or Professional | Suite integration and value may outweigh wider accountant familiarity | Bank connectivity, user/feature limits, adviser support |
| Side business with 8 clean transactions monthly | Spreadsheet or Wave Starter | Paid automation may not save meaningful time | Do not postpone the monthly close because volume is low |
Reddit’s useful warning: simple businesses can be over-softwared
Owner discussions often describe accounting products as too much system for a very small operation; other threads describe years of cleanup after owners trusted automation and stopped reconciling. Both can be true. The goal is not the fewest features. It is the smallest system with enough controls.
Use anecdotes to design tests: disconnect and reconnect a feed, create a refund, split a processor deposit, invite a bookkeeper, ask support a real question, and export everything. Do not turn one angry post or one referral link into a product verdict.
Set up the winner before you subscribe for a year
- Ask the tax professional. Confirm acceptable software, reporting, document workflow, and whether platform choice changes the fee.
- Build the chart of accounts. Keep categories aligned to decisions and tax reporting; do not create a category for every vendor.
- Connect one month. Import every account and compare opening/ending balances to statements.
- Test the sale path. Record gross sale, sales tax, fee, refund, and net deposit separately.
- Close on schedule. Reconcile, review uncategorized items and owner transactions, run reports, and export them.
- Define the review trigger. A new employee, inventory, second channel, multiple entities, or repeated close failure should reopen the decision.
