For UK businesses that need to invoice clients in multiple currencies, the leading software options in 2026 are Xero, QuickBooks Online, FreshBooks, Sage Accounting, Zoho Books, and FreeAgent. Xero is the most widely adopted by UK SMEs with international clients, but multi-currency invoicing is only included on its Comprehensive plan (£50/month) and above. FreshBooks (from £15/month) is the cheapest mainstream option with multi-currency on its entry-level paid plan. The right choice depends on the number of currencies you bill in, your accountant’s preferences, and how the software integrates with your bank and FX provider.
Who this guide is for
This guide is for UK businesses that bill clients in foreign currencies — freelancers and consultancies with overseas clients, e-commerce sellers receiving marketplace payouts, exporters, agencies servicing international accounts, and UK-based services firms with a non-domestic client base. It compares the leading software options on multi-currency support, pricing, and how they handle the foreign-exchange conversion at invoice time.
The currency challenge for UK businesses billing internationally
UK businesses with overseas clients face three connected problems. The first is invoicing in the right currency — most international clients prefer to be billed in their own currency, which means the invoice needs to show the amount in EUR, USD, AUD or another foreign currency. The second is recording the transaction correctly for VAT and accounting purposes, which HMRC requires in GBP at a defined exchange rate. The third is converting the foreign currency back to GBP when the client pays — ideally without losing 2–4% to a bank’s exchange rate margin.
Good multi-currency invoicing software solves the first two automatically. The third — the actual currency conversion — sits with your bank or FX provider, not the software. Combining the right invoicing tool with a competitive FX route is what makes the difference for margin. For the wider context, see our explainer on what an international money transfer is and the related guide on VAT and foreign currency invoices.
The leading multi-currency invoicing software compared
The table below summarises the main multi-currency invoicing options used by UK businesses in 2026. Critically, several providers only offer multi-currency on a higher tier — not their entry plan — so the headline starting price is often not the price you will actually pay if international clients are central to your business.
| Software | Multi-currency available on | UK monthly price (ex VAT) | Best for |
|---|---|---|---|
| Xero | Comprehensive plan and above | Ignite £16 / Grow £37 / Comprehensive £50 / Ultimate £65 | UK SMEs with international clients; accountant-friendly |
| QuickBooks Online | Essentials plan and above | Sole Trader Plus £10 (no VAT) / Simple Start £16 / Essentials £38 / Plus £56 / Advanced £123 | UK businesses needing strong reporting and integrations |
| FreshBooks | All paid plans | Lite £15 / Plus £25 / Premium £35 | Freelancers and consultancies invoicing internationally |
| Sage Accounting | Plus plan only | Start £15 / Standard £30 / Plus £59 | UK businesses preferring a long-established UK accounting brand |
| Zoho Books | Professional plan and above | Standard from £10 / Professional from £20 / Premium from £30 (plus Elite and Ultimate tiers) | Cost-conscious businesses with many currencies |
| FreeAgent | All paid plans (foreign-currency invoices supported) | Landlord £10 / Sole Trader £19 / Limited Company £33; free with NatWest, Royal Bank of Scotland, Ulster Bank or Mettle business accounts | UK freelancers and small businesses banking with NatWest group |
| Wave | Pro plan | Free (Starter) / $16/month (Pro) | Very small businesses with occasional foreign invoices |
Pricing is correct as of May 2026 and excludes VAT. Most providers offer a free trial; many also include discount pricing for the first 3–6 months. Always confirm current pricing on the provider’s UK website before subscribing.
How each tool actually handles multi-currency
Headline support for “multi-currency” looks similar across the providers that include it, but the day-to-day experience varies materially. The differences fall into four areas.
- Exchange rate sourcing. Xero, QuickBooks, and FreshBooks pull live rates daily from a wholesale data provider. Sage and FreeAgent allow manual rate entry, useful when you have a contractually agreed rate with a client. Zoho Books offers both.
- Bank feed reconciliation. If your foreign-currency receipts land in a UK bank account that auto-converts to GBP, you need software that can match the GBP-converted amount against the original foreign-currency invoice. Xero and QuickBooks handle this cleanly; smaller tools sometimes require manual reconciliation.
- Multi-currency receiving accounts. Some businesses use multi-currency receiving accounts with providers like Wise Business, Revolut Business, or specialist FX brokers, holding foreign currencies and converting only when needed. Most invoicing tools integrate with at least one of these via bank feed.
- VAT treatment. HMRC requires the GBP-equivalent value to be calculated using a defined exchange rate. Xero, QuickBooks, Sage, and FreshBooks all generate this automatically; smaller tools sometimes leave the calculation to the bookkeeper.
Worked example: a €20,000 invoice to a German client
Consider a UK consultancy invoicing a German client €20,000 with 30-day payment terms. Here is how a typical workflow looks across the major software options:
- Issue the invoice in EUR. The software generates the invoice showing €20,000 due, with the GBP equivalent recorded for VAT purposes at the day’s exchange rate (say 1.1700 GBP/EUR, equating to £17,094).
- Client pays €20,000 30 days later. The rate may have moved — if it has dropped to 1.1500, the GBP equivalent at receipt is £17,391.
- Bank or broker converts to GBP. A high-street bank charging a 3% margin would deliver £16,869 to the GBP account. A specialist broker charging 0.4% would deliver £17,322.
- Software reconciles. The invoicing tool matches the original €20,000 invoice against the GBP credit, calculates the FX gain or loss, and posts it to the books.
The difference between the bank route and the broker route on this single invoice is £453. Across 50 such invoices a year, that is £22,650 — not a marginal cost. The invoicing software does the recording; the FX provider determines what actually lands in the account.
Common mistakes to avoid
- Picking a low-tier plan that excludes multi-currency. Several providers gate multi-currency to a higher tier — including Xero (Comprehensive plan, £50/month), QuickBooks (Essentials, £38/month), Sage (Plus, £59/month) and Zoho Books (Professional). Check carefully before subscribing if international clients are central to your business.
- Letting your bank auto-convert at receipt. If euro receipts hit a UK GBP account, your bank will convert at its retail rate (often 2–4% margin). Holding the funds in a multi-currency receiving account and converting through a specialist broker captures most of that margin.
- Using inconsistent exchange rates between invoicing software and bookkeeping. HMRC accepts several published rate sources but expects consistency. See HMRC’s published exchange rates as a defensible monthly source.
- Forgetting the FX gain or loss line. Movement in the rate between invoice issue and receipt is a real accounting item. Most multi-currency software handles this automatically; ensure your bookkeeper or accountant reviews it monthly.
- Ignoring forward contracts on predictable invoices. Where you know an invoice is coming in 60 or 90 days, a forward contract can lock in today’s rate and remove the FX risk entirely.
How a currency specialist fits with your accounting software
Multi-currency invoicing software handles the books. A specialist FX provider handles the actual currency conversion. The two work side by side: software issues the foreign-currency invoice and records it in GBP for HMRC; the FX provider receives the foreign-currency payment, converts at a competitive rate, and pays the GBP into your business account. The software then reconciles the cleared GBP against the original invoice.
Anthony Bull, CEO of Cambridge Currencies, sees the cost difference clearly across our UK B2B clients: “Most UK businesses already have decent invoicing software in place. The cost leak is almost always at the conversion stage — receipts auto-converted by the bank at a 3% margin, often without anyone realising. Switching that one piece of the workflow to a specialist usually returns the equivalent of an extra invoice or two a year, without changing the software at all.”

Frequently asked questions
Xero is the most widely used by UK SMEs invoicing in foreign currencies, but multi-currency is only available on its Comprehensive plan (£50/month) and above. FreshBooks (from £15/month) and FreeAgent (free with NatWest group business accounts, otherwise from £19/month) are the cheapest mainstream options with multi-currency on their entry-level paid plans. The right choice depends on the number of currencies you bill in, your accountant’s preferences, and the integrations you need.
Use accounting software that supports multi-currency invoicing — Xero (Comprehensive plan and above), QuickBooks Online (Essentials plan and above), FreshBooks (all paid plans), Sage Accounting (Plus plan), Zoho Books (Professional plan and above), or FreeAgent. The software lets you issue an invoice in the client’s currency, automatically records the GBP equivalent for accounting purposes, and reconciles the payment when it is received.
Yes, but only on the Comprehensive plan (£50/month) and Ultimate plan (£65/month) — not on Ignite or Grow. Xero supports 160+ currencies, pulls live exchange rates daily, and records the GBP equivalent automatically for HMRC and VAT reporting purposes.
Yes, on the Essentials, Plus, and Advanced plans (starting at £38/month for Essentials). The Simple Start plan does not include multi-currency. QuickBooks supports 150+ currencies and integrates with most UK and US bank feeds.
HMRC requires the GBP-equivalent value of a foreign-currency invoice to be calculated using a defined exchange rate — typically the rate at the date of supply or HMRC’s published monthly rate. Multi-currency invoicing software calculates this automatically and includes both the foreign-currency amount and the GBP equivalent on the invoice.
Among UK options, FreshBooks Lite (£15/month) is the cheapest mainstream paid plan with multi-currency invoicing on the entry tier. FreeAgent is included free with NatWest, Royal Bank of Scotland, Ulster Bank, and Mettle business accounts, otherwise from £19/month. Zoho Books Standard (from £10/month) is cheaper but multi-currency requires the Professional plan.
Wave is a basic invoicing platform with multi-currency invoicing on the Pro plan ($16/month, around £13). For UK businesses billing in multiple currencies regularly, FreshBooks Lite (£15) or FreeAgent provide a stronger feature set tailored to UK accounting and VAT.
Hold the foreign currency in a multi-currency receiving account, then convert through a specialist currency broker rather than letting your bank auto-convert at receipt. Specialist brokers typically charge 0.1–0.6% margin compared to 2–4% from a high-street bank — the difference can be £500–£1,500 on a typical €20,000 invoice.
