eSourcing and RFx Software: RFI, RFP and RFQ Without Spreadsheets

eSourcing and RFx software lets you ask suppliers for information, proposals or quotes online, then compare the answers in one view. RFI asks what a supplier can do, RFP asks how they would solve a problem, and RFQ asks for a price on a defined need.

Best for: Buyers who send out RFIs, RFPs or RFQs several times a year
Replaces: Emailed documents and manual comparison sheets
Works alongside: Strategic sourcing plans, contract tools and supplier records
Biggest risk: Using an RFP when a short RFQ would do, and tiring suppliers out

Where this starts

The problem behind the purchase

Most RFP pain comes from admin, not strategy. Version control, late emails, a supplier who missed an addendum, a scoring sheet that three people edited at once. None of that helps you choose well. RFx software handles the admin so the team spends its time on the answers.

Before you buy

Five questions to put to every vendor

Can we reuse question sets across events?A library is where time is saved.
How do suppliers get clarifications?Fair processes need shared Q and A.
Can multiple evaluators score without seeing each other first?Independent scoring reduces bias.
What are the limits on attachments and file types?Large bids hit limits quickly.
Does the tool support public procurement rules we face?Rules differ by country and body.

What goes wrong

Three mistakes we see often

Sending an RFP for everythingUse RFQ for defined needs and RFI to find options.
Unclear specificationsVague requirements produce bids that cannot be compared.
No scoring plan before launchAgree weights first, or the loudest opinion wins.

Cost

How it is usually priced

Often per user or per event, or included in a sourcing suite. Some tools are free for suppliers. Public sector tools sometimes charge suppliers, so check who pays.

Questions

Frequently asked questions

What is the difference between RFI, RFP and RFQ?

RFI gathers information, RFP asks for proposed solutions and RFQ asks for prices on a fixed specification.

Can suppliers see each other's bids?

In a sealed bid event, no. Auction formats may show rank or price. Check the setting before you launch.

How long should an RFP run?

Long enough for good answers. Complex events often need several weeks, simple quotes a few days.
