The way to choose accounting software is to start from how your business actually handles money, then test two or three products against that list with real data. Feature comparison pages tell you what a product can do in general. They do not tell you whether it handles your invoices, your VAT treatment, your bank and your accountant's way of working.
A common cause of poor purchases is buying for the business you imagine in three years rather than the one you run today, or from skipping the question of who will actually use the system every day. This guide gives you a practical selection process: what to define first, which criteria matter, how to run a fair trial and where the hidden costs sit.
What accounting software needs to do
At its core, accounting software records every financial event once, in a ledger that follows double-entry rules, and produces reports from that ledger. A sale raises revenue and a receivable. A supplier bill raises an expense and a payable. A payment clears one of those and moves cash. If a product cannot do this reliably and show you the trail, nothing else it offers matters.
Around that core sit the jobs most small and mid-size companies need: sales invoices, supplier bills, bank reconciliation, VAT returns, expense claims, fixed assets and period-end reports. Payroll, inventory valuation and project costing are often separate modules or separate products.
Define your requirements before you look at products
Spend an afternoon writing down what goes through your books in a typical month. Count rather than guess. The numbers tell you which tier of product you are shopping for and stop a salesperson steering you toward one you do not need.
- How many sales invoices, supplier bills and bank transactions do you handle each month?
- Do you sell in more than one currency, or buy from suppliers abroad?
- Which VAT situations apply: standard and reduced rates, zero rating, reverse charge, imports?
- Do you hold stock, and does the ledger need to know its value?
- How many people need to enter data, approve payments or read reports, and what should each of them be allowed to see?
- Does your accountant work inside the system, or do they take an export at year end?
Add one more line: what must connect to it. Your bank, your online shop, your payroll provider and your stock system each create a manual re-keying job if they do not.
The criteria that decide the choice
Once you have your list, score each shortlisted product against criteria that map to your own answers. The table below is a working checklist you can copy into a spreadsheet.
| Criterion | What to check | Why it matters |
|---|---|---|
| Core ledger | Chart of accounts you can edit, journals, locked periods, audit trail | Your accountant needs to trust and correct the books |
| VAT handling | Rates, schemes you use, return preparation, digital submission where your country requires it | Wrong VAT is costly to correct later |
| Bank connection | Feeds from your bank, matching rules, handling of split payments | Reconciliation is the biggest recurring time cost |
| Invoicing and purchasing | Templates, credit notes, recurring invoices, bill approval | Determines how quickly you get paid and how safely you pay |
| Permissions | Roles, approval limits, separation between who enters and who approves | Controls fraud and error as the team grows |
| Integrations and export | Connections to shop, payroll and stock; clean export of all data | Avoids re-keying and lock-in |
| Reporting | Profit and loss, balance sheet, ageing, cash position, drill-down to transactions | You decide from these reports every week |
Standalone accounting or a wider business system
A standalone accounting package suits a company whose operations are simple: services, few stock lines, one or two people handling money. It is quick to set up and your accountant probably already knows it.
When you make, store or ship goods, the ledger depends on events in other departments: stock received, goods shipped, production completed. If those live in separate tools, someone re-types or imports the numbers, and mistakes appear at month end. We cover the trade-offs in our comparison of ERP and accounting software, and in the guide on what ERP software is. The practical test is simple: if you spend more than a few hours a month moving data between tools into the ledger, a more connected system deserves a look.
Run a fair trial with real data
Demos use clean sample data. Your business does not. Ask each vendor for a trial and give every product the same test month.
- Enter or import one month of real sales invoices and supplier bills, including awkward ones: a credit note, a foreign-currency bill, a part-payment.
- Connect the bank feed and reconcile the month. Note how many transactions match automatically and how long the rest take.
- Produce the VAT return figures and compare them with what you actually filed.
- Run the profit and loss and balance sheet and compare them with your current numbers. Differences point to setup or logic problems.
- Give your accountant access and ask what they would need to change.
- Let the person who will use it daily do the data entry, not the owner.
The product that feels slightly dull but produces correct numbers with little effort is usually the right one.
Count the full cost, not the subscription
The monthly fee is the most visible cost and rarely the largest. Add the one-off and ongoing items that change the total. Here is an illustration with stated assumptions: you migrate opening balances and a year of history, which takes 20 hours of your bookkeeper's time at £30 an hour, so £600. Training for three people takes 6 hours each at an internal cost of £25 an hour, £450. Running two systems in parallel for a month adds 10 hours of double entry, £250. That is £1,300 before the first subscription payment. These figures are assumptions for the example, not a price list.
Also ask about charges that grow with use: extra users, extra companies, bank feed fees, document storage, payroll per employee and support tiers. Request the price at twice your current volume so you can see how it scales.
Mistakes we see when companies choose
- Buying on feature count. Many teams use only part of the features they pay for.
- Ignoring the accountant. If they dislike the tool, you pay for the friction in their fees.
- Skipping the export test. Check that you can take all your data out in a usable format before you put it in.
- Migrating too much history. Opening balances plus the current year is often enough; keep older years in an archive.
- Switching mid-year without a plan. Start at a period boundary where possible, and keep the old system read-only.
Where Dika Ops fits
We built Dika Ops so that sales, purchasing, stock and the ledger run on one record, which removes the re-keying between tools. The person who drafts an accounting entry cannot approve it, and AI coworkers prepare work for a person to review rather than posting on their own. You can see how the accounting module works. Dika Ops is in closed beta and companies join a waitlist, so if you need to decide this quarter, run the trial above on the products you can access today.
If none of the packaged options match how you work, our custom software service builds the missing pieces, such as an integration or a reporting layer, around the system you already use.
Frequently asked questions
What is the best accounting software for a small business?
There is no single best product. The right one matches your transaction volume, your VAT situation and what your accountant can work with. Shortlist two or three, run the same test month in each and choose the one that gives correct numbers with the least effort.
Should I use cloud or desktop accounting software?
Most companies choose cloud software because bank feeds, access for your accountant and updates work without extra effort. Desktop software can still suit a single user with simple needs and strict data-location preferences. Check backup arrangements either way.
How much does accounting software cost?
Costs vary with the number of users, companies and modules, and vendor prices change, so check current pricing directly. Add migration, training and parallel running to the subscription for a realistic first-year figure.
Can I switch accounting software later?
Yes, but switching costs time and carries risk. Choose a product that exports your full data, and plan the change for the start of a financial period. Keep the old system available read-only for audit questions.
Do I need an accountant to help me choose?
It helps. Your accountant knows which tools cut their time on your file and which create rework. Ask them for their preference before you start the trial.
When should a growing company move from spreadsheets to software?
When errors or delays appear: invoices going out late, reconciliations that never quite agree, or VAT figures you rebuild by hand each quarter. At that point the cost of software is lower than the cost of the mistakes.
What is the difference between accounting software and an ERP?
Accounting software manages the ledger, invoices and reports. An ERP also runs the operations that create the financial events, such as sales orders, purchasing, stock and production, on the same data.
