The Business

SIG is an international industry-leading supplier of specialist insulation and building products. With over 75,000 customers, 440 branches, and an annual turnover of £2.7bn, the business is a central and valued distributor across the construction supply chain in the UK and across Europe.Establishing and maintaining strong working relationships across their supply chain is fundamental to SIG's projects and successes. With this in mind, the business identified that their current processes were not efficient enough. The business processes around 300,000 transactions annually, and improvements in this area would pass considerable benefits onto their customers.

The Challenge

SIG used traditional EDI to process a large number of their incoming supplier invoices, but using this technology, it was taking up to two weeks for their branches to process the transactions. SIG identified this as a significant issue, as it created problems with cash flow and forecasting, ultimately leading to payment delays to suppliers.

SIG also recognised that the complexity of their business, built through various acquisitions, was not well suited for traditional EDI. Each subsidiary had to be set up as a separate entity, creating a level of cost and administrative complexity that was becoming increasingly difficult to justify.

Pain point 1

Traditional EDI was taking up to two weeks for branches to process transactions, creating serious cash flow and forecasting problems and consistently delaying payments to suppliers.

2 weeks
Pain point 2

SIG's complex structure, built through acquisitions, meant each subsidiary had to be set up as a separate EDI entity, multiplying cost and administrative overhead across the business.

Pain point 3

Processing 300,000 transactions annually through a system that couldn't keep pace was creating downstream problems across the entire supply chain relationship.

It now takes a single day to process transactions, which is really incredible for us considering we were previously waiting two weeks.

The Solution

The decision was made to implement Open ECX's electronic invoicing. What impressed SIG so much about the solution was the fact it didn't impact their suppliers. Open ECX is open to all suppliers, regardless of size or technical capability, and doesn't require them to change their current processes or technology.With high levels of speed and accuracy through tailored business rules and advanced logic, Open ECX's electronic invoicing solution has enabled SIG to improve accuracy throughout their invoicing process and dramatically reduce processing time. The solution also provides in-depth visibility into every individual transaction, further reducing errors and delays, and strengthening supplier relationships across the entire supply chain.

How it worked
1
Open ECX's invoicing solution was implemented across SIG's multi-entity structure, removing the need for separate EDI setups per subsidiary and replacing a complex, costly arrangement with a single, consistent platform.
2
Suppliers could continue their existing processes without any changes. Open ECX handled validation and conversion at its end, making adoption simple regardless of supplier size or technical capability.
3
Tailored business rules and advanced logic were applied to SIG's specific invoicing requirements, improving accuracy at transaction level and giving the business in-depth visibility across all 300,000 annual transactions.

The Outcomes

Open ECX's electronic invoicing removed the need for considerable manual effort and time-consuming tasks for SIG's internal team, freeing them up to focus on more value-added tasks such as maximising sales. Supplier invoices are now processed within a day, a vast improvement on the two weeks they originally faced using traditional EDI.

The most important aspect of the new solution for SIG is the benefits they can pass onto their suppliers. Not only is the process fast, reliable, and accurate, but SIG also have high levels of control and visibility over their invoicing process, improving communication and ways of working with their supply chain.

Disruption to suppliers, regardless of size
The relationships we're now building with our suppliers are better thanks to Open ECX, and for us, that is the biggest benefit of the solution.
