An e-auction is a sourcing event in which suppliers submit bids electronically under defined rules. Its value is not limited to a lower price. Giving participants the same specification, deadline and evaluation conditions also helps the buyer explain how a decision was reached.
In a long email chain, identifying the latest valid quotation can become a job in itself. An e-auction brings line items, prices and commercial conditions into a common structure. However, moving an unclear specification onto a screen does not make it clear. Define the requirement first, then decide how suppliers will compete.
RFQs and e-auctions serve different purposes
A request for quotation, or RFQ, collects prices and commercial terms. An e-auction adds competition within a specified timeframe and set of rules. A sourcing exercise can start with an RFQ, proceed through technical qualification and continue with another round involving suitable suppliers.
The CIPS procurement cycle places the definition of requirements before supplier selection. For a buyer, that means replacing a description such as “office chair” with dimensions, load capacity, warranty, quantity and delivery location. If alternatives are acceptable, explain how they will be assessed. Otherwise, a cheaper substitute can appear to outperform an item that actually meets the requirement.
Choosing an auction format
Auction terminology varies across platforms and markets. The following descriptions refer to the purchasing formats used in Tenflex. Participants should understand both the bidding mechanism and the competitive information visible to them.
- Standard (English) auction: Suppliers can revise their offers. Depending on the chosen visibility settings, they may see their ranking or the best price. This does not necessarily mean every competing bid is disclosed.
- Dutch purchasing auction: The price starts low and increases in steps. The first supplier to accept wins under this purchasing model.
- Japanese purchasing auction: The price starts high and decreases in steps. Suppliers accept to remain active; a single remaining supplier can continue accepting down to its acceptable level.
- Sealed-bid auction: The buyer cannot see bid prices before the event closes. Bids are reviewed after the envelope is opened.
- Sales auction: Higher bids take priority when selling products or assets. Do not apply the lowest-price expectation of a purchasing event to this format.
The choice depends on the category and the market. Before selecting a format, consider how easily suppliers can understand the specification, how many qualified alternatives exist and whether non-price differences have already been resolved.
Preparing the first event
Ask the technical owner to confirm the line-item list. Quantities and units must be comparable: a price per box cannot be ranked against a price per individual piece without a conversion. Define questions about delivery, payment and quotation validity before issuing invitations. Mandatory answers can prevent important omissions from surfacing only after bidding ends.
Check that the invited contact is authorised to submit a quotation. State the closing time, time zone, bid revision rules and any automatic extension condition. Give first-time participants an opportunity to check access beforehand. In a short event, an unresolved login problem can affect competition just as much as a commercial decision.
Why the lowest displayed price can mislead
Consider an illustrative purchase of 100 units. Supplier A offers a total price of TRY 90,000 and supplier B offers TRY 93,000. If A charges another TRY 5,000 for transport, the first price column tells only part of the story. Differences in warranty or delivery conditions also need to be resolved before the buyer makes an award recommendation.
Record the quantity, scope and reference price used in any savings calculation. A reduction from the opening bid, a reduction against last year's purchase and a reduction in actual expenditure are different measures. Do not promise a standard savings percentage for every auction. Track the number of usable quotations and the time required to compare them as well.
Applying this in Tenflex
Tenflex combines RFQs, live auctions, line-item questions and additional bidding rounds. Its quotation report supports a review of prices alongside the information collected for evaluation. Choose the mechanism around your requirement, available suppliers and technical uncertainties. If the rules are not understood, the next useful action is a clearer invitation rather than a faster auction.
