If your business is in the UK
Wave's help centre says Wave is available for businesses located in the United States and Canada. For users outside those two countries, Wave says that product and customer support has stopped, and invoices and reminders can no longer be sent through Wave. Existing accounts stay open for now, but Wave says this may change.
So if you still keep UK books in Wave, it's worth exporting your data while you can see it, whether or not you move to Munshian Ledger.
Before you start: pick your conversion date
The conversion date is the first day Munshian Ledger keeps your books. Everything before it stays in Wave; everything from it onwards goes into Munshian Ledger. The easiest dates are the start of a VAT quarter or of your financial year, so no VAT return or year's accounts is split across two systems.
Sign up, add your business, then open Accounting › Import from another program and save your conversion date.
What to export from Wave
Wave exports some things straight from its reports, and others through Wave Connect, its add-on for Google Sheets. Install Wave Connect and link it to your Wave account first. The data then lands in a Google Sheet. Save each sheet from the Google Sheets File menu as an Excel (.xlsx) or CSV file, ready to upload.
| What | How to get it from Wave |
|---|---|
| Opening balances | Reports › Trial Balance, as at the day before your conversion date › Export › CSV |
| Chart of accounts | Wave Connect in Google Sheets: Extensions › Wave Connect › Download › chart of accounts |
| Customers | Wave Connect: Download › customers |
| Products and services | Wave Connect: Download › products |
| Unpaid sales invoices | Wave Connect: Download › invoices, including payment details. Keep only the ones still unpaid on the day before your conversion date. |
| Suppliers and unpaid bills | Wave's help centre says vendors and bills can be exported as well (see its Wave Connect article, which points to the steps). If that's not possible, type each unpaid bill into Munshian Ledger instead (see below). |
Sources: Wave's help articles on moving your data (trial balance export) and Wave Connect. Menus change. If one has moved, any CSV or Excel file with column headings works, and you can tell Munshian Ledger which column is which.
Tips for Wave files
- Munshian Ledger knows some of the column headings Wave uses, so it can often tell a file came from Wave and pick the columns for you. Check the choices on the review page before you import.
- If your dates are written month first (for example 03/31/2026), choose Month/day/year (US) on the review page.
- No file for an unpaid invoice or bill? Type it in on Accounting › Opening balances, with the customer or supplier, the number, the date and what was still owed. Or fill in the spreadsheet template on the import page and upload that.
Upload, check and finish
- Upload each file in the matching step. Munshian Ledger reads the columns and shows you every row before anything is saved.
- Match your old accounts to Munshian's UK chart of accounts, or keep your own codes.
- Compare the trial balance and the unpaid invoices and bills with Wave on the same date. The import page shows checks to help.
- Import your bank statements from the conversion date onwards (CSV, OFX or QIF) and reconcile them, so payments match the imported invoices and bills.
If an import isn't right, undo it and upload a corrected file.
What doesn't come across
- Transaction history: only the balances on the day before you switch, and the invoices and bills still unpaid. Keep reports and records from Wave for as long as HMRC needs you to (usually at least 6 years for a company).
- Receipts and attachments: download any you need from Wave first.
- Bank feeds: Munshian Ledger doesn't have live bank feeds yet. You upload statements from your bank instead.
- Payroll: Munshian Ledger doesn't run payroll. Use separate payroll software, and post the totals as a journal.
- Currencies: Munshian Ledger works in pounds, euros and US dollars only.
- VAT schemes: Munshian Ledger files MTD VAT returns to HMRC on the standard VAT accounting scheme. It doesn't do the Flat Rate or Cash Accounting schemes.
- MTD for Income Tax: Munshian Ledger can't send quarterly updates yet. See our MTD for Income Tax guide.
Questions
Can I move my books from Wave to Munshian Ledger?
Yes. Export your trial balance from Wave as CSV, and your chart of accounts, customers, products and invoices with Wave Connect, Wave's Google Sheets add-on. Save each sheet as a CSV or Excel (.xlsx) file, then upload it in Munshian Ledger under Accounting › Import from another program. Each file is checked and shown to you before anything is saved, and each import can be undone.
Is there a direct connection between Wave and Munshian Ledger?
No. There's no automatic link. You export files from Wave and upload them to Munshian Ledger, which reads the columns and lets you check every row before it saves anything.
Does my full transaction history come across from Wave?
No. Munshian Ledger brings across where the business stood on the day before you switch: the balance of every account, plus the invoices and bills still unpaid. Keep your old transactions and reports from Wave for your records.
How much does Munshian Ledger cost?
Munshian Ledger is free, with every feature included and no card needed to sign up.
