Free Accounting Software: What's Actually Free and What It Costs You Later
The four kinds of free accounting software, what each one really includes, and the point at which free stops being the cheapest option.
Yes, there is free accounting software, and for a very small business it can be the right choice. It comes in four kinds: free tiers of commercial products, open-source programs you install yourself such as GnuCash or Odoo Community, spreadsheets, and the invoicing or bookkeeping tools some banks give their business customers. Each is genuinely free to use. What differs is what is capped, what the vendor earns from instead, and which costs show up later: migration, missing controls, manual filings and your own time.
This article is not an argument against free software. It is a description of what you get, so that the decision is made on facts.
The four kinds of free
| Kind | Examples of the category | What is free | How the provider earns |
|---|---|---|---|
| Free tier of a commercial product | Entry plans with limits on invoices, users or features | Core invoicing and bookkeeping up to the cap | Upgrades when you hit the cap; payments processing; payroll add-ons |
| Open-source, self-hosted | GnuCash, Odoo Community edition and similar | The software itself, with no cap | Hosting, support and the enterprise edition, sold to those who want them |
| Spreadsheets | A sheet of income and expenses | Everything, with no structure | Nothing; the cost is entirely your time |
| Bank-provided tools | Invoicing or bookkeeping inside a business bank account | Simple invoicing, categorisation of transactions from that one bank | Account fees and lending; the tool keeps you at the bank |
What is actually free, and what is capped
Free tiers of commercial products usually limit one or more of: the number of users (often one), the number of invoices or customers per month, bank feed connections, document storage, support (community only), and the modules available (payroll, inventory, multi-currency and the API are commonly excluded). Filings and e-invoicing are, in our reading of published plans, very rarely in a free tier, because national returns and Peppol or clearance channels cost the vendor money to maintain.
Open-source software has no caps, but the hosting, backups, updates and localisation are yours. Odoo Community, for example, needs a server, a database, country localisation modules and someone to apply updates. GnuCash runs on one computer and is single-user by design.
Spreadsheets have no caps and no controls. Nothing prevents an edited history, an unbalanced entry or a formula error, and nothing produces a VAT return.
Bank tools are limited to that bank's accounts and typically to invoicing and categorisation. They rarely hold a full general ledger, and leaving the bank means leaving the tool.
The costs that arrive later
These are the costs that do not appear in the first month and are the reason free software is sometimes the most expensive option over three years.
Migration. When you outgrow the free tool, the history has to move: opening balances at minimum, usually open invoices and fixed assets, sometimes the full journal. The cheaper the tool, the less structured its export tends to be. Budget days of work, or an accountant's hours.
Missing audit trail. Free tools, and spreadsheets in particular, often let any entry be edited or deleted without a record. That is fine until a tax inspection, an investor's due diligence or a dispute with a customer, when the question "what did the books say on that date" has no reliable answer. The glossary entry on immutable ledgers explains what the alternative looks like.
No period locking. Once a VAT return is filed, the figures it was based on should not change. Without a lock, a back-dated entry silently makes the filed return wrong, and nobody notices until the next inspection.
No VAT registers or returns. The software records invoices but does not produce the national VAT return, the EU sales list or, where required, the invoice registers. Someone assembles them by hand every month. In Lithuania that is the i.SAF registers and the FR0600 return; every country has its equivalent.
Manual filings. Payroll declarations, Intrastat, annual accounts and e-invoicing mandates all have to be done somewhere. If the software does not do them, you or your accountant do, at an hourly rate.
Time. The largest cost and the least visible. Manual bank reconciliation, re-keying supplier invoices, assembling returns and fixing spreadsheet errors are hours every month. At any reasonable value of your time, they exceed a small subscription quickly.
Dependence. A free tier that changes its limits, a bank tool that disappears when you change banks, or an open-source project that stops being maintained each force a migration at a time you did not choose.
When free is the right choice
- You are below your country's VAT registration threshold and have no employees, so your filings are an annual tax return and little else.
- Your volume is small: a handful of invoices and bank lines a month.
- An accountant does your year-end from your records and is happy with the format.
- You are testing a business idea and may stop within a year.
- For open-source: you or someone on the team genuinely wants to run and maintain it, and will keep doing so.
In these cases the controls a paid system adds protect against risks you do not yet have, and the money is better spent elsewhere.
When free is not the right choice
- You are VAT-registered and file monthly or quarterly returns.
- You have employees and payroll declarations.
- You sell to consumers in other EU countries and need OSS, or you import low-value goods and need IOSS.
- You are in a country with an e-invoicing mandate, or about to be.
- Your own software creates transactions: a storefront, a subscription billing system, a marketplace.
- You expect to raise money, be audited or sell the company, and the books need to stand up to review.
- You have more than one legal entity.
At this point the free tool's missing controls stop being theoretical. The cost of getting the VAT return wrong, or of a back-dated entry after filing, is larger than any subscription.
The comparison with a small metered plan
The relevant comparison is not free versus an expensive suite. It is free versus the cheapest paid plan that has the controls. Nordlet's Starter plan is one data point; others exist.
| Typical free tier | Nordlet Starter | |
|---|---|---|
| Monthly fee | €0 | €10, excluding VAT |
| Users | Often one | Unlimited |
| Companies | One | Unlimited |
| Modules | Core invoicing and bookkeeping; payroll, inventory, API and filings usually excluded | Every module: invoicing, ledger, bank, inventory, payroll, assets, revenue recognition, VAT and OSS/IOSS returns, Peppol, consolidation, full API |
| Volume | Capped by invoices or customers | 3,000 requests a month included, then €0.004 per request |
| Audit trail and period locking | Varies; often absent | Every change logged; locked periods reject postings with HTTP 409 |
| Bank feeds | Often limited or paid | PSD2 feeds, camt.053 and MT940 import, Stripe import; 10 imported movements count as one request |
| Trial | The free tier is the trial | 14 days with €5 of trial credits, no card required; unlimited sandbox companies afterwards |
A sole trader issuing ten invoices a month and importing fifty bank lines uses perhaps forty requests, so the fee is the €10 base. What the €10 buys is the audit trail, the period lock, the VAT return produced from the books and the ability to leave with a complete export. Whether that is worth €120 a year depends on which of the two lists above describes you. The full price list is on the pricing page, and our pricing guide explains the models other vendors use.
If you start free and move later
Plan the move before you need it.
- Keep a clean record of every invoice number, with no gaps, from day one. Numbering rules apply whether or not your software enforces them.
- Reconcile to the bank monthly, even in a spreadsheet, so the opening balances at the switch are known.
- Keep supplier invoices as files, named by date and number.
- Pick a cut-over date at a period end, usually a year end or a VAT period end.
- Use the new system's importer rather than re-keying. Nordlet's migration importer takes the chart of accounts, partners, opening balances or full history, open invoices, fixed assets and stock in one call, and validates the whole package before writing anything.
FAQ
Is there any completely free accounting software?
Yes. Open-source programs such as GnuCash are free without caps, and several commercial products have free tiers. The software is free; hosting, maintenance, filings and your time are not, and the free tiers cap volume or features.
Is free accounting software safe to use for a VAT-registered business?
It can record the transactions, but most free tools do not produce the national VAT return or lock periods after filing, so the compliance work is manual and the filed figures are not protected from later changes. For a registered business those two gaps usually cost more than a small subscription.
What is the difference between free and open-source accounting software?
Free tiers are a vendor's entry plan with limits, hosted by the vendor. Open-source software is code you can run yourself without limits, where hosting, updates and support are your responsibility or bought separately.
Can I use a spreadsheet as my accounting system?
For a very small, non-VAT-registered business with an accountant doing the year-end, many do. A spreadsheet has no audit trail, no balancing check and no returns, so it stops being adequate once filings become monthly or the business has more than one person entering data.
How much does the cheapest paid accounting software cost?
Published entry plans for mainstream products in 2026 are typically in the range of ten to twenty euros a month before add-ons. Nordlet's Starter plan is €10 a month excluding VAT with every module included and 3,000 requests.
