About

Pay-as-you-go at just €0.029 per envelope. No minimums, no contracts, no surprises. Every customer gets a dedicated workspace with secure template and document separation.

About

The digital age of document signing is here! TaxCalc eSign Centre dramatically reduces the time spent obtaining client approval for tax returns, VAT returns and other sets of documents. Simply send over an electronic copy of the document, ask the client to check and sign – you’ll be notified immediately and you can submit the document straightaway. Using our tried and trusted SimpleStep workflow, preparing documents for electronic sign-off couldn’t be easier. Clients can sign on any device - smartphone, tablet, laptop and desktop – from anywhere at any time. You pay by envelope – and can buy envelopes in blocks. The more envelopes you buy, the more inexpensive it becomes. Upload externally-saved PDFs and TaxCalc generated documents (which now includes Companies House Forms) to eSign envelopes, bringing you one step closer to a paperless office.
