Choosing Accounting Software in 2026: A Buyer's Checklist
The eleven capabilities that decide whether accounting software fits your business, and the pricing traps that appear at renewal rather than at signup.
By Emily Richardson · Reviewed by Legamoney Editorial Team
Accounting software is a five-year decision disguised as a monthly subscription. Migrating ledgers mid-year is painful, so the sensible approach is to test the software against the work you actually do — not against a feature grid.
Key takeaways
- Per-seat pricing and per-entity pricing behave very differently once you add a bookkeeper or a second company.
- Bank feed coverage is the single most common reason a migration fails — check your specific bank before you commit.
- The IRS expects records that substantiate every deduction; export format matters more than dashboard design.
- Multi-currency, inventory, and payroll are the three modules most often sold as expensive add-ons.
- Ask for the renewal price in writing: introductory discounts commonly cover only the first twelve months.
In this guide
Start with your filing obligations
Whatever you choose has to produce the records your tax authority expects. In the US that means substantiation for every deduction claimed, retained for the applicable assessment period. Confirm the software can export a general ledger, a trial balance and transaction-level detail in a plain format your accountant can open without buying the same subscription.
The eleven checks
- Bank and card feeds for your actual institutions, with a documented refresh frequency.
- Reconciliation tooling that lets you unreconcile a period without deleting transactions.
- Invoicing with partial payments, credit notes, and your tax jurisdiction's required fields.
- Sales tax or VAT handling by jurisdiction rather than a single flat rate.
- Multi-currency with a documented revaluation method, if you sell abroad.
- Accountant access as a free user, not a paid seat.
- Attachment storage for receipts, with bulk export.
- An audit trail that records who changed what and when.
- An open API or scheduled CSV export, so your data is portable.
- Payroll: either built in and filing on your behalf, or an integration you have verified.
- Published renewal pricing, not just the promotional first-year rate.
Cost modelling before you sign
Model three years, not one month: base plan at list price, plus seats you will realistically add, plus the add-ons for payroll and inventory. Compare that against the hours of bookkeeping the software genuinely removes. Our business savings calculators will do the arithmetic if you want the totals side by side.
Run a two-week trial that mirrors real work
A demo shows what the vendor wants you to see. A useful trial imports one real bank month, one real supplier bill with an attachment, one credit note and one payroll journal, then closes and reconciles the period. If any of those four steps needs a workaround in week one, it will need the same workaround every month for five years.
Migration: what actually has to move
- Opening balances agreed to your last filed accounts, signed off before the first transaction is entered.
- The full customer and supplier ledger, including open invoices and credit notes, not just contact names.
- Chart of accounts, mapped line by line rather than auto-matched.
- At least the statutory retention period of historic transactions, exported and stored independently of both systems.
- Recurring invoices, direct debit mandates and bank rules, all of which are commonly forgotten until the first missed collection.
What the total cost usually looks like
Budget the subscription at list price, an implementation cost of several days of your own time, a bookkeeper's time to check the first two closes, and the add-ons you will add in year two. Businesses that under-budget almost always do so by ignoring the second and third of those, not the first.

Frequently asked questions
Is cloud accounting software required for tax filing?
No. Tax authorities require adequate records, not a particular product. Cloud software makes reconciliation and export easier, but a well-kept spreadsheet with supporting documents still satisfies the recordkeeping rules.
When is the safest time to switch accounting software?
The first day of a new financial year. Mid-year migrations force you to carry opening balances and part-year transactions across, which is where most reconciliation errors appear.
