QuickBooks

QuickBooks is an accounting platform with invoicing included. According to QuickBooks' UK pricing information, its plan range includes Sole Trader Plus, Simple Start, Essentials, Plus and Advanced. The page lists invoicing and payments, recurring invoices, bank feeds, VAT support and accountant access, with additional multi-currency features on Essentials and inventory features on Plus.²

QuickBooks may suit businesses that want invoicing and bookkeeping together, particularly where estimates, expense capture, reports and accountant collaboration are part of the workflow. The advertised prices are exclusive of VAT, and payroll is a paid add-on, so check the plan and any add-on costs before committing.²

Sage

Sage offers products for sole traders, small businesses and larger organisations. According to Sage's UK product information, its sole-trader product includes an MTD-focused free-plan option, while Sage Accounting is aimed at businesses with one to 19 employees. Sage's page advertises introductory Accounting pricing from GBP 2, then GBP 20 a month excluding VAT, and identifies invoice creation and late-payment chasing as capabilities of its payments agent.³

Sage may suit a business that wants invoicing close to wider accounting, VAT or payroll workflows. Check the precise product, promotion end date, renewal price and the features included for your business size.

Simplybill

Simplybill is a lighter invoicing tool for businesses that want to create and manage invoices without a full accounting platform.

According to Simplybill's pricing information, all new accounts receive a 14-day trial. After this, the free plan is limited to three invoices a month. Basic costs USD 5 a month and includes up to 25 invoices a month, Enhanced costs USD 15 a month and includes up to 100, and Premium costs USD 25 a month with unlimited invoices. The pricing page also lists unlimited quotes, reminders, customised templates and email alerts across paid plans.⁴

Simplybill may suit a freelancer or small business that mainly needs straightforward quotes and invoices. Its pricing is in USD, so UK businesses should factor in their own card or currency-conversion costs where relevant.

According to Zoho Books' UK pricing information, its Free plan includes invoices, quotes, expenses, payment reminders, recurring invoices, bank-transaction reconciliation and VAT returns.

The same pricing page identifies bank feeds, progress invoicing and recurring expenses on Standard. Professional adds vendor bills and payments, purchase and sales orders, multi-currency transactions and inventory features. Higher plans add more advanced inventory and reporting functions.⁵

Zoho Books may suit a small business that wants invoicing, expenses, bills and reporting in one system. Check the feature limits and user allowance for the specific plan, especially if you need projects, inventory or multi-currency transactions.

How to know which invoicing software is the best for your particular business

The right choice depends on how your business invoices, gets paid and keeps its books. Before comparing providers, map the work the tool needs to handle.

Invoice volume and automation

If you send a handful of invoices each month, a basic tool may be enough. If you send dozens or hundreds, look for invoice templates, recurring invoices, automatic reminders, payment-status tracking and a useful dashboard for overdue payments.

VAT, accounting and bank feeds

If invoicing feeds into your accounts, consider VAT workflows, bank feeds, expense capture, accountant access, payment matching, tax reports and exports. A dedicated invoicing tool can work well for simpler needs, while a full accounting platform can reduce the number of systems you manage.

Customer payment methods

Some tools let you add card, Direct Debit or payment-link options to invoices. Check the applicable payment fee, settlement timing and whether the route works for the customers you serve.

International invoicing

If customers pay from abroad, check whether the software can issue invoices in the needed currency, give clear payment instructions and reconcile the incoming payment. Also consider what happens after the customer pays: whether you can receive, hold, convert or spend the money in the currency that works for your business.

Users and permissions

A sole trader may need one login. A larger business may need different access for directors, finance teams, accountants and sales staff. Check user limits, approval settings and audit trails before committing to a plan.

Why is it worth syncing Wise Business with your accounting software?

FAQs

What is the best invoicing software for a small UK business?

There isn't one best option for every small business. FreshBooks may suit service businesses, Simplybill may suit a business that wants basic invoicing, and Zoho Books, QuickBooks and Sage may suit businesses that also need wider accounting features. Compare invoice volume, VAT needs, payment methods, user access and budget before choosing.^1,2,3,4,5

Is free invoicing software enough?

It can be enough when invoice volume and reporting needs are low. Check the limits on invoices, users, customers, payment methods, exports, VAT support and recurring invoices before relying on a free plan. For example, Simplybill's free plan is limited to three invoices a month after its trial, while Zoho Books' Free plan includes a broader group of accounting features.^4,5

Can invoicing software handle recurring invoices?

Many tools can, but availability can depend on the plan. FreshBooks lists automated recurring invoices, Zoho Books lists recurring invoices and QuickBooks lists recurring invoices in their plan information.^1,2,5

Can I use invoicing software without accounting experience?

Yes. A dedicated invoicing tool can be a sensible place to start when you mainly need to create, send and track invoices. If you need VAT returns, bank reconciliation, expense management, stock control or more detailed reporting, consider whether an accounting platform or an accountant's support would better fit your needs.

Can I use Wise Business with invoicing software?

Wise Business can sit alongside an invoicing or accounting tool for eligible businesses that need to receive, hold, convert or send money across currencies. Your chosen setup should match how customers pay and how your business uses the money after an invoice is settled.

What should I check before moving invoicing software?

Check that you can access or export customer records, open invoices, payment history, recurring invoices, credit notes and the reports you need. Also check what needs to be reconnected, such as payment methods, bank feeds, accounting integrations and customer portals.
