Apex Billing
Automated self-billing VAT invoicing.
Self-billing invoices, raised and sent automatically on your suppliers' behalf
Apex Billing UK is a self-billing platform that lets UK businesses create, calculate and send VAT invoices to their own suppliers, rather than waiting for suppliers to invoice them. It automates the VAT calculation, formatting and email delivery of every invoice, turning what is normally a manual paperwork exercise into a process that runs itself.
The workflow is deliberately simple: add a supplier once, enter the amount to be paid, and Apex Billing calculates VAT and totals, generates a properly numbered PDF invoice, emails it to the supplier, and logs it for tracking and export.
The problem it solves
Businesses that pay suppliers on a recurring, self-billing basis — construction firms paying subcontractors under CIS, recruitment agencies paying temporary or self-employed workers, companies paying royalties or commissions, scrap and recycling buyers, and marketplace operators paying sellers — traditionally have to run a manual reconciliation job every period: collating amounts, working out the correct VAT treatment, formatting compliant invoices and chasing them out to suppliers. Apex Billing automates that job end to end, removing the recurring administrative burden.
Core features
- Supplier management — a central record of each supplier's contact details, VAT number and agreement dates, entered once.
- Automated invoice creation — enter the payment amount and VAT and totals are calculated automatically.
- Full VAT rate support — standard, reduced, zero and exempt rates, plus construction industry reverse charge.
- Bulk import — upload a spreadsheet to generate multiple supplier invoices in one pass.
- Numbered, compliant invoices — properly formatted with the details a valid VAT invoice requires.
- Automatic email delivery — invoices are sent to suppliers as PDFs without manual intervention.
- VAT return export — generate VAT totals ready to drop into a VAT return filing.
- Tracking and reporting — monitor sent invoices and payment status, and export data as needed.
Who it's for
UK businesses that regularly raise payments to suppliers rather than receiving invoices from them — including construction companies operating CIS and reverse charge, recruitment agencies, royalty and commission payers, scrap and recycling operators, and marketplace platforms paying out to sellers.
