Use Case · Invitation for Bid
The IFB submitted compliant, every time.
An IFB comes down to price and responsiveness. The owner already knows what they want. Your job is to return a compliant, clearly priced bid before the deadline closes.
What it is
Invitation for Bid (IFB), explained.
An Invitation for Bid, sometimes called an Invitation to Tender, is a price-driven solicitation for a well-defined scope. The owner already knows what they want, so the award goes to the lowest responsive and responsible bidder. Responsive is the key word. A single missing form, an unsigned page, or an unacknowledged addendum makes the bid non-responsive, and then the price no longer matters. The work is less about writing and more about airtight completeness under a hard deadline.

Why it's hard
Where IFBs go wrong.
Zero margin for error. One missing form or unsigned page and you are non-responsive. Price does not matter.
Late-breaking addenda. Owners drop changes right up to the deadline, and every one has to be acknowledged and priced.
Bond and insurance paperwork. Third-party documents have their own lead times and can stall the final submission.

FAQ
IFB questions, answered.
What is an Invitation for Bid (IFB)?
An IFB is a solicitation for a clearly defined scope where the award goes to the lowest price among bidders who meet the requirements. It is common in construction and goods, where the owner has already specified exactly what they need.
What makes a bid non-responsive?
A bid is non-responsive when it fails a mandatory requirement, like a missing form, an unsigned page, an addendum nobody acknowledged, or a bond that is not in order. Those bids are set aside no matter the price. Stepscale tracks every required item and flags gaps before the deadline.
How is an IFB different from an RFP?
An IFB is decided on price for a fixed scope. An RFP is scored on a technical proposal and approach. Choose an IFB when the requirements are fully defined, and an RFP when you want firms to propose how the work should be done.
