MTD Bridging Software vs Full Accounting Software
Bridging software and full accounting software both have a place. The right option depends on your business size, record-keeping process and whether you want to keep using Excel.
| Feature | MTD Bridging Software | Full Accounting Software |
|---|---|---|
| Best for | Excel users and spreadsheet-based businesses | Businesses wanting a full bookkeeping system |
| Workflow | Keep existing spreadsheets | Move records into a new platform |
| Learning curve | Usually lower | Usually higher |
| Cost | Often lower or pay-per-filing | Often monthly or annual subscription |
| Bank feeds | Usually limited or not included | Often included |
| Invoicing and reporting | Usually handled in your existing process | Often built into the platform |
| MTD submission | Yes, if compatible with HMRC requirements | Yes, if compatible with HMRC requirements |
