What is eSourcing?

eSourcing (electronic sourcing) means using web-based software to choose suppliers. You use it to find and qualify suppliers, send RFIs, RFPs and RFQs, run online auctions, compare bids and award the contract. eSourcing ends when the contract is awarded. Ordering and payment come after that, in eProcurement or procure-to-pay systems.

Software does not save money by itself. You save money when several qualified suppliers compete on a clear requirement. eSourcing software helps you do this the same way every time, and it keeps a record of each step. If your current process is poor, moving it online will not fix it.

Short answer. eSourcing works best when you follow these four rules:

• Qualify suppliers and settle specifications before any price event
• Match the event to the category: RFI, RFP, RFQ or auction
• Tell suppliers the award rules in advance, and follow them
• Agree with finance how savings will be calculated, before the event

Key takeaways

Topic	Key point
Cost savings	US federal agencies reported reverse auction savings from about 12% to over 23% in fiscal years 2012 to 2014
Preparation	Most of the result depends on work done before the event: the specification, the supplier list and the award rules
Automation	Let the software collect and compare bids and keep records. Let people decide the strategy and the award
Suppliers	Suppliers take part and bid properly when the rules are clear and the buyer follows the result
Scope	eSourcing works best when several suppliers can meet a clear requirement. It helps little when only one supplier can do the work

What are the benefits and limits of eSourcing?

The main benefits of eSourcing are more suppliers competing, faster sourcing events, easier bid comparison and a full record of every decision. To get these benefits, you also need to do some preparation. This table shows what you need for each one.

Here is one example of savings. The US Department of Energy reported average reverse auction savings of about 14% per contract, according to a 2015 White House procurement memo.

eSourcing also has limits. It helps little in three situations: only one or two suppliers can do the work, you cannot write a clear requirement, or the relationship matters more than the price. In these situations, an online auction is unlikely to lower the price. Negotiate directly instead, and save the records in the same system.

How is eSourcing different from traditional sourcing?

Traditional sourcing uses email, spreadsheets, phone calls and meetings. Records end up in many places, and buyers compare bids by hand. eSourcing runs the same steps in one system. You can see everything in one place, reuse your templates and show why you made each decision.

Our comparison of traditional sourcing and eSourcing covers the differences in more detail.

Which eSourcing event should you use?

Your choice depends on what you already know. If you don’t know who can supply the item, start with an eRFI. If you know exactly what you need and several suppliers can provide it, use an eRFQ and consider an auction.

In a reverse auction, suppliers bid against each other in real time and the price falls. A forward auction runs the other way: your organization is the seller, buyers bid against each other, the price rises and the highest bid wins.

A reverse auction works well when you have at least three qualified suppliers, a measurable specification and price is an important factor. Finish the technical evaluation before bidding starts. If you don’t, the lowest bid may come from a supplier whose product you cannot accept.

How does the eSourcing process work?

A typical eSourcing event has six steps. It is one part of the wider strategic sourcing process, which also covers spend analysis and category strategy.

1. Plan the purchase. Write down the requirement, the current price, the timeline, the team and the award rules. Decide the award rules now, before you see any bids.
2. Qualify suppliers. Use an eRFI and your supplier records to identify and prequalify suppliers. Only invite suppliers you would be willing to buy from.
3. Collect proposals or quotes. Issue an eRFP or eRFQ with a structured response format. Keep all questions and answers in the shared log.
4. Run an auction where it fits. Train suppliers first and test the setup. Set each supplier’s maximum bid at its own earlier quote, so it can only offer a lower price.
5. Evaluate and award. Score bids using the criteria you shared with suppliers. Get approvals in the system, then award the contract the way you said you would.
6. Hand over and take notes. Move the result into contract management and supplier onboarding. Write down what worked, so you can use it in the next event.

What should you automate, and what should stay with people?

Let the software do repetitive work and keep the records. Let people make the commercial decisions. Teams often get this split wrong in one of two ways. Some leave repetitive work with people, so buyers still copy bids into spreadsheets by hand. Others leave decisions to the software, so its score picks the winner and nobody can explain why.

Automate	Keep with people
Invitations, reminders and deadlines	Category strategy and which event to run
Question logs and document distribution	Writing the specification
Collecting and comparing bids	Deciding which suppliers qualify
Scoring against weights you have set	Setting the weights
Approval routing and the audit trail	The award decision and any exceptions
Standard reports on participation and savings	Managing supplier relationships

How do you keep suppliers engaged in eSourcing?

Suppliers take part and bid properly when they believe the process is fair. They need to know how you will evaluate them, what other suppliers can see, and whether the event will really decide who wins.

• Before the event, tell suppliers how you will evaluate bids, how many suppliers will win and what share each will get
• Give every supplier the same information, using the shared question log
• Train suppliers on the platform and run a practice event for anyone new to it
• Follow the result, and do not negotiate further after an auction closes
• Never place fake bids, and never invite suppliers you do not plan to buy from

If you break these rules, suppliers remember. Next time they may not take part, or may not give you their best price. For more on this, read why suppliers need not fear reverse auctions.

What are the common eSourcing challenges, and how do you solve them?

The most common eSourcing challenges are internal resistance, slow supplier adoption, poor data, integration and skills gaps. Most of these are people and process problems, so more software features will not solve them.

How does eSourcing support compliance and data quality?

eSourcing helps with compliance in two ways. Templates and approval steps make sure each event follows your policy. The system also records every invitation, bid, change and approval, so you can show an auditor why a supplier won.

These records also show you supplier performance, spend and price trends over time. This data is only useful if it is accurate. Make one person responsible for it, set clear rules for entering supplier records, and check them regularly. Our article on how eSourcing improves compliance and ROI goes further on this.

How much can eSourcing save?

Savings vary by category and customer, so treat published figures as examples and not as a forecast for your own events.

• Army, Homeland Security, Interior and Veterans Affairs reported about 12% savings on more than $800 million of reverse auction purchases in fiscal year 2012.
• The US Department of Energy reported average savings of about 14% per contract.
• The US General Services Administration reported savings for agencies using its reverse auction platform: 19% in fiscal year 2013 and more than 23% in fiscal year 2014.
• Procter & Gamble saw 9.6% in recommended savings, as described in the case study below.

The US government figures come from a 2015 White House procurement memo. The memo says agencies generally calculated savings by comparing their own cost estimate with the auction’s closing price. So these figures are only as accurate as those estimates.

When you see a savings figure, ask what it was compared with. A large saving means little if the starting price was too high. Before each event, agree with finance which starting price to use: the last price paid, the budget or the quote before the auction. Then report two numbers: the savings agreed in the event, and the savings you actually got after buying. Only the second number lowers your costs.

Some benefits are harder to measure, such as better supplier relationships, stronger compliance and better control of spend.

What does eSourcing look like in a large company? The Procter & Gamble case

Procter & Gamble sourced over $3 billion through electronic bidding and optimization in the two and a half years to March 2005. It saw $294.8 million (9.6%) in recommended savings, according to a paper in the journal Interfaces. Staff from P&G and from its software provider wrote the paper together.

P&G wanted to look beyond the lowest price in a reverse auction. Suppliers sent electronic offers that showed what they could do and where they could save cost. P&G entered its own limits and preferences. Optimization software then worked out how much business each supplier should get.

The paper reports these results:

• Over $3 billion sourced electronically
• $294.8 million (9.6%) in recommended savings
• Implementation in weeks instead of months
• Supply networks redesigned, using data to compare the options
• Demand matched to the most efficient way of producing, which the authors say helped suppliers without cutting their margins

The main lesson is that P&G asked for more than a price. Suppliers could show where they were able to supply at lower cost. P&G then used that information to decide who got what share of the business. A price-only auction does not collect this information.

How does eSourcing differ by industry?

The process is the same in every industry, but the main priority changes. For manufacturers, also read our eSourcing best practices in manufacturing.

What should you look for in eSourcing software?

Look for software that fits the way your team works and that suppliers find easy to use. Ask these questions about each tool on your shortlist, and test it on a real purchase:

Capability	Question to ask
Event management	Can it run eRFIs, eRFPs, eRFQs and the auction formats you need?
Bid analysis	Can it compare bids on total cost and non-price factors, as well as price?
Supplier experience	Can a new supplier register and bid without installing software or paying a fee?
Supplier management	Does it keep qualification records and participation history?
Collaboration	Can your team and approvers work in the same event?
Integration	How does it connect to your ERP, procure-to-pay, contract and supplier systems?
Reporting	Can it report savings against the baseline you agreed?
Security and support	What certifications does it hold, and who helps you during a live event?

How does Krinati support eSourcing?

Krinati is an eSourcing platform with six integrated modules, and suppliers pay nothing to take part in events.

• RFX management runs RFIs and RFQs using spreadsheet-style pricing sheets, drag-and-drop questionnaires and automated supplier scoring. Bids are assessed as suppliers submit them, and configurable approval workflows govern the award.
• Reverse auctions cover reverse, forward and Dutch formats, with multi-line bidding, weighted non-price parameters and supplier-specific ceiling prices.
• Sourcing intake lets any user raise a sourcing request from a mobile-first form. Approved requests flow into RFX and auction events with no re-entry.
• Supplier management keeps a central vendor master with onboarding, document verification, categorization and performance tracking.
• Contract management holds agreements in one repository, with alerts for expiry and renewal dates.
• Managed services add Krinati experts for program management, training and event support, including running auctions on the customer’s behalf.

What comes next for eSourcing?

AI and predictive analytics are the technologies most likely to change daily sourcing work. They will help most with tasks that use a lot of data: finding suppliers, analyzing bids, drafting event documents, assessing risk and forecasting prices and demand.

Be more careful with blockchain and the Internet of Things. Both are useful in some supply chains. But neither fixes the usual reasons a sourcing event fails: an unclear specification, too few qualified suppliers or unclear award rules.

Sourcing teams will need new skills: data analysis, enough knowledge of AI to check its results, and the ability to help colleagues adopt new ways of working. They will still need to know how to set up events and judge suppliers.

How do you get started with eSourcing?

Start with one purchase category that is likely to succeed, then add more. One good result will convince your colleagues faster than any presentation.

1. Check you are ready. Make sure you have a senior sponsor, a budget, colleagues who will take part and reasonably clean data for your first categories.
2. Pick the first category. Choose one with clear specifications, at least three qualified suppliers and a business user who supports the event.
3. Select the platform. Test it on that category, with a few of your actual suppliers if you can.
4. Set the rules. Create templates, agree the approval steps and decide how you will calculate savings.
5. Train people. Train buyers and suppliers separately. Give both a person to call during live events.
6. Run, report and add more. Share the results with colleagues, fix what didn’t work, then add more categories.
