Best RFQ Software for Suppliers: 8 Tools (2026)

Every guide to RFQ software makes the same assumption: that the RFQ is already a document sitting on your desk. They compare content libraries, answer automation, and proposal assembly. All useful. All downstream of the part where suppliers actually lose the deal.

Because for most suppliers, the RFQ does not arrive as a document. It arrives as an email, into sales@ or quotes@ or info@, where it sits alongside 200 other messages until somebody notices it.

Key takeaways

• Best overall for RFQ email management: InboxPilot, which is us. Most RFQs arrive as email, not portal submissions, and InboxPilot is the tool built for that intake layer: triage, routing, and grounded draft replies inside Gmail or Outlook.
• Only 45% of RFP submissions go through online portals, according to Loopio's 2026 benchmark of 1,500+ companies and 250,000+ RFPs. The majority arrive by other channels, mostly email.
• 88% of manufacturers and distributors have lost deals to inefficiencies in how quotes get generated and approved (TrendCandy for Aleran, July 2025, n=200, margin of error ±4.6%).
• Best RFQ response platform: Responsive for enterprise teams, Loopio for high-volume repeatable responses, AutoRFP.ai if you want published pricing.
• Not for you: SAP Ariba, Coupa, Jaggaer, Zycus. Those are your customer's tools. See why.

First: "RFQ software" means two opposite things

Search "RFQ software" and you will be shown SAP Ariba next to Loopio, as if a supplier could use either. They sit on opposite sides of the transaction.

If you are reading this because quote requests keep landing in your inbox, you are on the supplier side. Buyer-side platforms are how those requests reach you. Buying one will not help you answer them. Skip every listicle that mixes the two, which is most of them.

The thing nobody in this category writes about

Here is a statistic that appears in nearly every RFQ software article, quoted approvingly, with nobody noticing what it means.

Loopio's 2026 RFP benchmark, built from more than 1,500 global companies and over 250,000 RFPs, reports that only 45% of submissions go through online portals. (Loopio)

Turn that around. The majority of RFPs and RFQs do not arrive through a portal. They arrive through email, forwarded PDFs, spreadsheets attached to a message from a buyer you have never met, and requests dropped into a shared address that three people half-watch.

Every RFQ platform in this post is excellent at the second half of the job. Not one of them touches the first half. They assume you already have the document. They do not triage a shared mailbox, they do not route an inbound quote request to the right engineer, and they do not draft the acknowledgement that keeps you in the running while you work up the real numbers.

That gap is where deals die, and the data says so.

What slow intake actually costs

In July 2025 the research firm TrendCandy surveyed 200 decision-makers at US manufacturers, wholesalers, and distributors with 100+ employees on behalf of Aleran (margin of error ±4.6% at 95% confidence). The findings:

• 88% have lost deals because of inefficiencies in how quotes are generated and approved.
• 71% take at least a full day to produce a quote.
• Only 37% have fully automated quoting.
• Manual workflows leak roughly 5% of annual revenue.

(Aleran press release, corroborated by Digital Commerce 360)

Note what that first number is not saying. It is not "88% lost deals because their proposal was weak." It is inefficiency in generating and approving quotes. Much of that is upstream of the proposal entirely.

A note on the speed-to-lead statistics everyone quotes

You will see two famous numbers in every article on this subject: that responding in 5 minutes rather than 30 makes you 100 times more likely to make contact, and that responding within an hour makes you 7 times more likely to qualify a lead.

Both are real. Both are also from 2007 and 2011, and both measured phone calls to inbound web leads, not RFQs to suppliers. The 100x figure comes from Dr. James Oldroyd's Lead Response Management study (MIT/InsideSales, 2007). The 7x figure and the finding that 23% of audited companies never responded at all, with an average response time of 42 hours, come from the Harvard Business Review audit of 2,241 US companies (Oldroyd, McElheran and Elkington, HBR, March 2011).

We are citing them with their dates attached because most articles in this category do not, and quietly implying that 19-year-old phone-call data is fresh 2026 RFQ research is exactly the kind of thing that should make you distrust an article. Treat them as directional. The direction is not in dispute.

Category one: RFQ and RFP response platforms

These build the response. All of them assume you already have the document. Pricing in this category is almost universally quote-only, and we have not invented a single number below.

1. Responsive (formerly RFPIO)

The largest install base in the category, and the right fit for enterprise proposal teams with a real content library and the headcount to maintain it. Deep workflow automation, and strong real-time extraction from knowledge documents.

The cost of that depth is the ramp. TechTarget explicitly cites a steep learning curve, pricing is opaque, and implementation is a project rather than a purchase. Quote-only: the procurement aggregator Vendr reports observed contracts between roughly $7,000 and $28,000 per year, averaging about $13,955. That figure is Vendr's observation, not Responsive's published price. (Vendr)

2. Loopio

Built for teams responding to a high volume of repeatable RFPs, RFIs and security questionnaires. The interface is intuitive, content library reuse is strong, and Loopio publishes the best benchmark data in the category, which is genuinely useful whether or not you buy the product.

TechTarget notes a longer implementation than competitors. Foundations also starts at a 10-seat baseline, so it is not built for the one-person quoting desk. Pricing is quote-only, confirmed on Loopio's own pricing page ("book a call to build a custom quote"). (loopio.com/pricing)

3. Arphie

Aimed at mid-size teams that want AI-native drafting and fast onboarding. It prices per project with unlimited users rather than per seat, which is unusual and buyer-friendly. Generated answers carry source citations, and it will explicitly say "I don't know" rather than hallucinate, which matters more than it sounds.

It is also a newer and smaller vendor, with reported gaps in reporting depth, mobile and export. Its marketed "84% AI acceptance rate" is a vendor claim, not an audited figure. Pricing is quote-only, on a concurrent-project model.

4. AutoRFP.ai

The only tool in this category with published pricing, which in a market this opaque is worth something on its own. Scale is $899 per month and Accelerate $1,299 per month billed annually, with Enterprise on request. It suits teams handling 10 or more requests a month who want to know the price before booking a call. It ingests messy Excel and Word formats, and a browser extension lets you work inside procurement portals.

One caveat on sourcing. The vendor is also a prolific content marketer that publishes comparisons of its own competitors, so discount its self-assessments accordingly.

5. Tribble

For teams that want answers grounded in the systems they already use: retrieval across Gong, Slack and CRM, fast implementation, native Google Docs and Sheets, win/loss analytics.

Two things to weigh. Credit-based usage pricing makes cost genuinely hard to forecast. And it is an asynchronous document tool, so it has nothing to offer during a live procurement call. Quote-only, sold as monthly credit packs.

6. SiftHub

SiftHub covers the full lifecycle including the go/no-go decision, which most tools skip, plus governance and review routing. That makes it the pick for teams that need bid/no-bid qualification and structured SME coordination rather than drafting alone. TechTarget notes a longer implementation, and it is a smaller vendor. Pricing is quote-only.

7. Upland Qvidian

Mature content library, strong governance, and a G2 rating of 4.3 out of 5 across roughly 150 reviews. It suits regulated industries, financial services and insurance in particular, that need compliance trails and access control more than they need a modern interface.

Which is fortunate, because the interface is the standing complaint: reviewers widely criticize it as dated, with slow search and a complex implementation. You will also see a "$15,000 to $25,000" price floated online. It originates from a direct competitor's blog, so we are not repeating it as fact. Officially it is quote-only. (uplandsoftware.com/qvidian)

8. Ombud

Easy to use, with OmMatch autofill and structured collaboration, aimed at mid-market response teams focused on content reuse. Content-freshness management is a chore, collaborative editing gets awkward on long documents, and import and export are rigid. Pricing is quote-only and fully custom.

Category two: the email layer, where RFQs actually arrive

These are not substitutes for the platforms above. If an RFQ is a 200-question document, you need a response platform. If it is an email you have not opened yet, that is a different problem. Most suppliers have both, and only buy for one.

Unlike the response platforms, everything here publishes its price.

Price the seats you will actually fill. A five-person quoting desk is $125 a month on Front Starter or Hiver Growth, $95 on Gmelius Meli, $70 on Missive Starter, and $120 on Missive Productive once you want the AI. Add a sixth person and every one of those numbers goes up. InboxPilot is metered by AI draft rather than seat, so the same five people cost $29 or $149 depending on volume alone. Whether that is cheaper depends on which of the two is growing faster for you: your headcount, or your inbound.

InboxPilot

This is our product, and this is the one category in this post where we will claim the top spot, because it is a narrow claim: triage and first response on inbound RFQ email, inside the inbox you already use. It fits suppliers whose quote requests land in a shared Gmail or Outlook mailbox and sit there too long.

It watches sales@ or quotes@, recognizes a quote request when one arrives, labels and prioritizes it, routes it to the right rep or engineer, and drafts a first reply grounded in your product docs, pricing and past responses. The buyer gets an acknowledgement with real content in minutes instead of a silence that lasts two days.

The tradeoffs, plainly. It is not an RFP response platform. No content library, no proposal document assembly, no compliance matrix, no bid/no-bid workflow. It does nothing about the 33 hours Loopio says a full RFP response takes, and if that is your bottleneck you should buy Loopio and not buy us. Pricing is metered by AI draft rather than per seat, which is cheaper than per-seat tools for a small quoting desk and worth doing the math on if you run high volume. And we are newer than the incumbents, with a shorter public track record.

Free covers 25 AI drafts. Hobby is $29 a month, Standard $149 (1,500 drafts, unlimited inboxes, knowledge base grounding), Pro $499 (12,000 drafts, advanced routing, SSO), Enterprise custom. Annual billing is about 20% less, putting Standard at $119 a month. (inboxpilot.co/pricing)

Front

A full customer operations platform built around the shared mailbox, which suits larger sales teams. Mature rules engine, strong analytics, omnichannel.

Watch the headline price. The AI that does the drafting is a paid add-on, $20 per seat per month for Copilot and Autopilot from $0.05 per conversation, so the real cost sits well above the $25 entry. Starter also caps you to a single channel type. Listed tiers are Starter $25 per seat per month, Professional $65, Enterprise $105. (front.com/pricing)

Hiver

Native in Gmail, with a free tier, an AI copilot from the entry paid tier, and round-robin routing that maps well to assigning quotes to reps. The natural fit is a Google Workspace quoting desk that will not leave Gmail.

The catch for this audience is Microsoft. Hiver is Gmail-first, and Outlook requires the separate Omni product, which matters because most manufacturers run on Microsoft 365. Reviewers also report performance lag at volume. Free, then Growth $25 per user per month annual, Pro $55, Elite $85. (hiverhq.com/pricing)

Missive

The cheapest entry here at $14, with a powerful rules engine, up to 1,000 rules on Productive and above, and it is provider-agnostic. Good for small quoting teams on a budget who want to discuss a quote inside the thread.

The $14 Starter tier has no AI and no integrations, and AI requires buying credits separately, so the plan you actually want is Productive at $24. Business is $36 per user per month. (missiveapp.com/pricing)

Gmelius

Shared inbox plus Kanban, for Gmail-only teams. That last part is the whole story here: Gmail only, no Outlook, which for a manufacturer or distributor is usually disqualifying on its own. Meli $19, Growth $25, Pro $40 per user per month annual. (gmelius.com/pricing)

What to look for

1. Work out which half of the problem is actually costing you

Two very different failures look the same from the outside:

• You are losing bids you responded to. Your response is too slow to assemble, or not good enough. Buy a response platform.
• You are losing bids you never responded to. The RFQ sat in a shared mailbox for three days, or went to the wrong person, or nobody realized it was time-sensitive. No response platform will help you. Fix intake.

Most suppliers have both problems and only buy for the first, because that is the only one the market sells against.

2. Confirm you are being sold a supplier-side tool

If the demo shows you inviting vendors and scoring bids, you are looking at a buyer-side procurement suite. Politely leave.

3. Insist on a real price

Almost this whole category is quote-only. That is a choice, not a necessity: AutoRFP publishes $899 and $1,299, and every email-layer tool publishes per-seat pricing. If a vendor will not give you a number before a discovery call, that tells you something about the sales cycle you are about to enter.

4. Check Outlook support before the feature list

Most manufacturers and distributors run on Microsoft 365. Gmelius does not support Outlook at all, and Hiver's Gmail product does not either. That fact eliminates tools faster than any feature comparison.

5. Ask what happens to the RFQ before it becomes a document

This is the question the entire category is built to avoid. Ask it on every call: how does the quote request get from my customer's email to your platform? The answer, in every case, is that someone on your team does it manually.

How to choose, in one paragraph

If you run a proposal team responding to structured, document-heavy RFPs, buy a response platform: Responsive if you are enterprise, Loopio if volume is high and repeatable, AutoRFP if you want to know the price today. If you are a supplier whose quote requests arrive as email into a shared mailbox and the real problem is that they sit there, no response platform will help you, and that is the narrow case where InboxPilot is built to help. Most growing suppliers eventually want both, and the intake layer is the cheaper of the two to fix first.
