What Is Procurement Software?
Procurement software is a digital platform that manages the purchasing process from request to payment. It handles purchase requisitions, approval workflows, purchase orders, supplier records, invoice matching and spend reporting, so every purchase is controlled, traceable and audit-ready.
Without it, purchase requests arrive by email or chat, approvals depend on chasing managers, and finance teams struggle to see where money is going.
Core functions include:
- Purchase requisitions and approval workflows
- Purchase order (PO) creation and tracking
- Supplier and contract management
- Invoice matching (2-way or 3-way)
- Budget tracking and spend analytics

InvoiceNow: What Singapore Businesses Should Know
InvoiceNow is Singapore’s national e-invoicing network, based on the international Peppol standard. IRAS is progressively requiring GST-registered businesses to send invoice data through InvoiceNow-ready solutions:
- Since 1 November 2025: newly incorporated companies that register for GST voluntarily
- From 1 April 2026: all new voluntary GST registrants
- By April 2031: all GST-registered businesses, under a phased schedule announced at Budget 2026
What this means for procurement: when you shortlist procurement or AP software, ask whether it’s InvoiceNow-ready or integrates with an InvoiceNow-ready accounting system. Choosing a compatible system now avoids a second migration later.
Check IRAS’s GST InvoiceNow Requirement page for the timeline that applies to your business.

Where Lark Fits in Your Procurement Process
Lark isn’t procurement software. It doesn’t replace purchase order management, invoice matching or supplier risk tools. It helps with the collaboration around procurement:
- Lark Approval to set up simple purchase request and approval workflows, which suits smaller teams before they invest in dedicated procurement software
- Messenger and Docs for discussing requests, negotiating terms and co-editing contracts with finance, operations and management
- Lark Base to track suppliers or requests in a shared, structured database
For businesses with high purchase volumes, use dedicated procurement software for transactions, and Lark for the communication and approvals around them.
Frequently Asked Questions
What is the best procurement software?
It depends on your company size. SAP Ariba, Coupa, Oracle Procurement and GEP SMART suit large enterprises. Procurify and Precoro suit growing SMEs and mid-market businesses, and ProcurementExpress suits small teams that mainly need purchase orders and budget control.
What is the difference between procure-to-pay and source-to-pay software?
Procure-to-pay (P2P) software covers the process from purchase request to supplier payment. Source-to-pay (S2P) goes further, adding supplier sourcing, tenders, contract negotiation and supplier risk management.
Do small businesses need procurement software?
Once purchasing involves several requesters, approvers or suppliers, procurement software helps prevent lost requests, unapproved spending and invoice errors. Very small businesses can start with simple approval workflows and move to dedicated software as purchase volume grows.
What is InvoiceNow, and does it affect procurement software?
InvoiceNow is Singapore’s national e-invoicing network. IRAS is progressively requiring GST-registered businesses to send invoice data through InvoiceNow-ready solutions, with all GST-registered businesses covered by April 2031. Check that your procurement or accounting software supports it.
What features should procurement software have?
Look for approval workflows, purchase order management, invoice matching, supplier management, budget and spend visibility, accounting or ERP integration, InvoiceNow readiness for Singapore, and an interface employees will actually use.
Can I use Lark for procurement?
Lark can handle simple purchase request approvals, supplier tracking and procurement discussions, but it isn’t dedicated procurement software. Businesses with higher purchase volumes usually combine procurement software with Lark for collaboration.
Final Thoughts
The best procurement software is the one that matches your company size and purchasing complexity. Enterprises need full source-to-pay suites, while SMEs usually get more value from simpler procure-to-pay tools that teams adopt quickly. For Singapore businesses, check InvoiceNow readiness early, and support your procurement system with clear collaboration and approvals across departments.
