Digital signature management and archiving of billing & invoicing documents


An international food conglomerate needed to comply with customer demands and governmental business standards. They decided to implement digital signature management and archiving of its billing & invoicing documents so that the documents would be digitally signed and sealed. This would eliminate the use of printed and manually signed (aka wet) signatures for internal & customer approvals that created inefficiencies and non-compliances on regulatory requirements.

The solutions & services provider had to fulfil the following criteria:
• Handle about 200 thousand invoices per year.
• The ability to digitally sign billing documents but to automatically archive them across all their sales organizations.
• The solution had to handle the following billing documents.

o Domestic tax invoice

o Credit memo

o Debit memo

o Export invoice

o Credit for Returns

o Custom invoice

o Bill of supply

o Tax Invoice GST Inter-state (from stock transport order outbound

Industry Outlook

The growth of the digital signature management solutions market is driven by the high acceptance of digital signatures in internal processes or communication in enterprises leading to enhanced operational efficiency and reduction in costs. The growing need for data security and authentication necessitated by the increase in cyber-attacks also drives the market's growth. However, factors such as resistance to variation of existing applications or systems and the high cost of investment are affecting the market's growth. Opportunities for market growth come from innovation in technology, an increase in the adoption of cloud-based solutions, and new legislation encouraging the use of digital signatures.

The global digital signature market was valued at $3.56 billion in 2020, and is projected to reach $61.91 billion by 2030, growing at a CAGR of 33.2% from 2021 to 2030.
