The best self-billing software for a UK business handles the things that make self-billing compliant and fast: a proper UK VAT engine (including the CIS reverse charge at 20% and 5%), per-supplier VAT status and agreements, sequential numbering, bulk CSV runs, and automatic supplier copies. Here’s a checklist to compare options.
Key points
- A UK VAT engine with standard, reduced, zero, exempt and reverse charge.
- CIS reverse charge (20% and 5%) and CIS deductions.
- Per-supplier VAT status and agreement tracking.
- Sequential numbering, bulk CSV import, and emailed supplier copies.
Compliance features
Look for correct UK VAT treatments, the CIS domestic reverse charge, the required self-billing markings, unique sequential numbering, and record-keeping of agreements and supplier VAT numbers.
Speed and scale
If you pay many suppliers, bulk CSV import and automatic emailed copies matter. Statements and remittance advice help both sides reconcile.
Cost and fit
Check pricing scales with your supplier and invoice volume, and that suppliers don’t need paid accounts to receive their copies.
