Mid-market accounting software UK: when to move up

Mid-market accounting software sits between small business packages such as Xero, QuickBooks and Sage Accounting and large enterprise systems. Businesses usually move up when they run several companies, need many users or handle complex stock, and their month-end depends on spreadsheets. This page lists the signs, the main UK options and what they cost, using each provider’s own pages checked on 6 November 2026.

What is mid-market accounting software?

Mid-market accounting software is a finance system built for businesses with more entities, users and transactions than a small business package expects. Most are sold as cloud ERP (enterprise resource planning), which links the ledger to purchasing, stock, projects and reporting.

There is no official definition of “mid-market”. In practice it covers growing SMEs and groups, often with a finance team rather than a single bookkeeper. The systems are usually sold and set up through a partner, not bought online with a card.

When should you move up from Xero, QuickBooks or Sage?

You should consider moving up when the workarounds cost more than the software. Use this checklist.

• You consolidate group accounts in spreadsheets. Each company sits in its own subscription and you combine them by hand.
• You hit user or feature limits. For example, QuickBooks UK lists Advanced with up to 25 users, and Xero Ultimate includes payroll for 10 people.
• You trade in several currencies across several entities and revalue them manually.
• You need approval workflows, such as purchase orders signed off before a supplier is paid.
• You run stock, manufacturing or projects that need more than basic tracking.
• Your auditors want stronger controls, such as audit trails, role-based access and locked periods.

If only one of these applies, an app that connects to your current package may be cheaper. See our guides to accounting software for multiple businesses and software with inventory.

Does company size change what you need?

Yes, because larger companies have more reporting duties. Companies House’s Life of a company guidance, updated 23 October 2026, sets these limits for periods from 6 April 2025. A company must meet two of the three to fall in a category.

The employee limits are 50 for small and 250 for medium. A medium-sized company normally needs an audit, and a medium-sized parent company must prepare group accounts when it meets the medium group criteria. Multi-entity software that consolidates group results makes both easier. Read more on company size thresholds.

What are the main mid-market options in the UK?

The table lists four systems alphabetically, with how each provider prices. We do not rank them; the right choice depends on your industry and partner.

Acumatica. The Acumatica pricing page says you pay for the applications you use and the transaction resources you need, “not for user seats”, and advertises unlimited users. Quotes come through a partner.

Microsoft Dynamics 365 Business Central. Microsoft’s UK pricing page lists Essentials at £61.50 and Premium at £84.60 per user a month, paid yearly, plus Team Members at £6.20. Prices exclude VAT. Microsoft provides the UK localisation itself, according to its country availability list.

Oracle NetSuite. NetSuite’s ERP page says customers pay an annual licence made up of the core platform, optional modules and the number of users, plus a one-time implementation fee. Its OneWorld edition handles multiple subsidiaries, currencies and real-time consolidation.

Sage Intacct. Sage also sells Sage Intacct, a cloud finance system aimed above its small business range. Sage’s UK pages blocked our access on 6 November 2026, so we have not printed its prices or features; ask Sage or a partner for a quote.

How much does mid-market software cost?

Expect to pay far more than a small business plan, and budget for set-up as well as licences. As an example, 10 Business Central Essentials users cost 10 × £61.50 = £615 a month, or £7,380 a year excluding VAT, before any partner fees (our calculation).

By comparison, Xero Ultimate is £70 a month excluding VAT for the whole organisation. See our Xero pricing and QuickBooks pricing guides. Implementation, data migration and training are usually quoted separately by the partner.

How do you plan the move?

Plan the move as a project with a fixed start date, ideally a new financial year. Follow these steps:

1. List your requirements. Entities, users, currencies, stock, approvals and reports.
2. Shortlist two or three systems and ask each partner for a written quote covering licences, implementation and support.
3. Check Making Tax Digital. Confirm the system files VAT returns directly or through bridging software on HMRC’s MTD for VAT software list.
4. Decide what history to migrate. Many firms bring over opening balances and keep the old system read-only.
5. Run a parallel month before switching off the old package.

Our guide to switching accounting software covers the cut-over in detail.

Frequently asked questions

What is the difference between accounting software and ERP?

Accounting software records the ledger, invoices and tax returns. ERP links the ledger to other operations such as purchasing, stock, manufacturing and projects in one system.

When has a business outgrown Xero or QuickBooks?

Common signs are consolidating several companies in spreadsheets, hitting user limits, complex multi-currency trading and needing approval workflows or stronger audit controls.

How much does Microsoft Business Central cost in the UK?

Microsoft lists Essentials at £61.50 and Premium at £84.60 per user a month, billed yearly and excluding VAT, checked on 6 November 2026.

Does NetSuite publish UK prices?

No. NetSuite charges an annual licence based on the core platform, modules and users, plus a one-time implementation fee, and quotes each customer separately.

Do I need ERP to prepare group accounts?

Not necessarily, but multi-entity software makes consolidation much easier. A medium-sized parent company must prepare group accounts when it meets the medium group criteria.
