Zyntra OS by Double Support

Invoicing software for companies in the UK

In Zyntra OS a quote your customer accepts from a link becomes the invoice, the invoice its payment, and every one of them reaches the books by itself. For a company in the United Kingdom, Zyntra OS keeps the books in pounds sterling with VAT on each line, and reads UK banks through GoCardless.

Zyntra OS, national e-invoicing for a sample company

More than printing an invoice

An invoice is the end of a sale and the start of a payment. A program that only prints it leaves the quote in an e-mail, the payment in the bank and the balance in a spreadsheet. In Zyntra OS the quote, the invoice, the credit note, the payment and the customer statement are one record, and a package counts its users only — as many invoices, customers and items as your work needs.

For a company in the UK

Payments: Stripe, Mollie, Klarna and PayPal

Your customer pays an invoice online by card through Stripe, Mollie or Adyen, with PayPal, or later with Klarna.

Peppol e-invoices

An invoice sent as Peppol BIS Billing 3.0 to a customer who receives Peppol e-invoices, switched on in the company's settings.

Call center teams

Questions from companies in the UK

Is there a limit on invoices?

No. A package counts its users only; you add as many invoices, customers and items as your work needs.

Can a customer accept a quote online?

Yes. The customer opens the proposal from a link and accepts it, and it goes on to the sales order and the invoice.

Does Zyntra OS work for a company in the United Kingdom?

Yes. A company starts in pounds sterling, charges VAT on each line, reads its bank accounts through GoCardless and takes payments through Stripe, Mollie, Klarna or PayPal. Zyntra OS is made by Double Support, a software company in Amman, Jordan.

Does Zyntra OS send VAT returns to the UK tax office?

No. It keeps the VAT you charged and paid in the accounts, line by line; it does not send returns to the UK tax office.
