When you pay hundreds of suppliers a period, raising invoices one by one isn’t practical. Bulk self-billing lets you upload a CSV of the period’s data and create a whole batch of compliant self-billed invoices at once, preview them, then send. It’s how agencies, marketplaces and networks run weekly or monthly payouts.
Key points
- Upload a CSV to create a whole period’s invoices at once.
- Preview before confirming and sending.
- Correct VAT per supplier across the batch.
How bulk import works
You export the period’s data — timesheets, commission or payouts — to a CSV, upload it, and the software creates one self-billed invoice per supplier with the correct VAT. You preview the batch before confirming and sending.
Getting VAT right at volume
Each supplier’s VAT status drives the treatment, so VAT is added only where due across the whole run. Apex Billing matches suppliers, applies their VAT status, and can email every copy automatically.
This is general information, not tax advice — confirm your own position with your accountant or HMRC (see VAT Notice 700/62 on self-billing).
