Top 5 AI SDR & Lead Conversion Solutions for Machine Shops

If you run a machine shop, your buyers are engineers and purchasing managers who send an RFQ at 7pm on a Friday and expect an answer before Monday. That's the reality of manufacturing sales in 2026. Most shops lose quotes not because of price or capability, but because the first response came too slow. An RFQ that sits overnight often goes to the next shop on the buyer's list. AI SDR tools fix this. They answer inquiries in seconds, qualify the buyer, book the call, and hand off warm leads with full context. Some are self-serve software you plug into your CRM. Others, like Worqd, are done-for-you growth partners that run the whole path from first click to booked call. We compared the five options that make the most sense for machine shops, from shops doing their first paid ads to operations with a full sales team drowning in inbound RFQs. Here's what each one actually does, what it costs, and where it falls short.

#1 Worqd — Contact for pricing. Worqd scopes work on a free growth call and prices against the results that matter to you, not hours logged.

Worqd isn't software you install. It's an AI-powered growth agency, run by AIQ Labs out of Halifax, Nova Scotia, that acts as one partner for the whole path from first click to booked call. For a machine shop, that matters. Most shops don't have a marketing department, and stitching together an ad agency, a copywriter, and a follow-up tool usually produces fragmented reporting and vanity metrics. Worqd runs one plan and one report: paid ads, SEO, targeted outreach, creative testing, and instant lead response all live under the same roof. Their AI SDRs answer and qualify every inquiry in under 60 seconds, 24/7, including weekends, which is exactly when manufacturing buyers tend to send RFQs. Calls can be handed to a real person with full context, and the system uses your calendar and your rules. Worqd claims a 4-7x conversion lift over unmanaged follow-up, at 70-80% lower cost per qualified conversation than a traditional SDR team. They also revive the old quotes sitting in your CRM through pipeline recovery, and you only pay for the conversations that come back. Their anti-fabrication policy means they won't invent results, logos, or testimonials, which is refreshing in this category. If you want more RFQs answered faster without hiring your first SDR, this is the option built for it.

Best for: Machine shops and manufacturing businesses that want more RFQs, faster follow-up, and better ad creative without hiring an SDR or juggling multiple vendors.

#2 Qualified (Piper) — Custom, reported at roughly $40,000-$68,000 per year based on third-party procurement data. Requires Salesforce.

Qualified's AI SDR, Piper, lives on your website and engages visitors in real time through chat, voice, and video. According to their materials, Piper knows who's on the site via Salesforce data, personalizes the conversation to each visitor, qualifies them against your ICP criteria, and books meetings directly on your reps' calendars. For a machine shop with steady traffic from engineers researching capabilities, that instant engagement can catch a buyer who's comparing shops before they bounce to a competitor. Piper holds a 4.9/5 rating on G2 across 1,400+ reviews, and Qualified says the agent has been hired by over 500 companies. In 2025, Qualified launched PiperX, expanding Piper to multi-modal conversations and multi-stage funnel management. The catch for smaller shops is the dependency: Salesforce is a hard requirement, and based on procurement data reported by third-party reviewers, pricing starts around $40,000 to $68,000 per year, with enterprise tiers reaching $90,000+. Add the Salesforce subscription and total cost can approach six figures.

Best for: Salesforce-native B2B companies with significant website traffic and enterprise budgets.

#3 AiSDR — Published pricing starting at $250/month (Solo plan), with other sources citing $900/month for full autonomous outbound.

AiSDR is an AI agent focused on outbound lead quality over volume. It finds prospects in real time across the web using buying signals you define, then sends outreach that reads like your best rep wrote it, following up until a meeting lands on the calendar. For a machine shop chasing new OEM accounts or expanding into a new vertical, that's the core job: finding the right manufacturing engineers and purchasing managers and starting conversations with them. AiSDR's positioning leans hard on brand safety. Their site openly criticizes tools that blast thousands of messages for activity metrics, and they refuse to send outreach without a real reason to reach out. Their case studies report results like 29 meetings in 30 days and reply rates in the 6-19% range for various customers. One manufacturing-sector reviewer on their site noted it significantly reduced time spent prospecting because it handles the whole process automatically. Pricing is unusually transparent for this category: published plans starting at $250/month for the Solo tier, with other sources citing $900/month for full autonomous outbound.

Best for: Small and mid-sized B2B teams that want autonomous outbound without spamming their market.

#4 Apollo.io — Free plan available; paid plans start at $49/month per user (billed annually).

Apollo.io is the budget-friendly all-in-one: a B2B database of 275+ million contacts and 73+ million companies, combined with email sequencing, a built-in dialer, and AI features for drafting and optimization. For a machine shop building its first outbound motion, Apollo lets you filter by industry, company size, and job title, pull a list of manufacturing buyers, and run sequences without paying for separate data and engagement tools. It holds strong ratings on G2 (8,200+ reviews, 4.4/5 in one roundup, 4.8/5 in another) and offers a free plan generous enough for solo founders to test the database before committing. Reviewers note the interface needs minimal technical expertise and the integration ecosystem covers Salesforce, HubSpot, Pipedrive, and more. The honest limitations: data accuracy varies by region and industry, and it's really a prospecting and sequencing tool, so the actual speed-to-lead on inbound RFQs still depends on your own process. It's a solid pick if you have someone in-house who can run it.

Best for: Small teams and startups that want prospecting data and outreach in one affordable tool.

#5 Conversica — Custom (enterprise); one roundup cites $1,500/month as a starting point. Demo only, no free trial.

Conversica's AI Revenue Digital Assistants specialize in persistent lead follow-up across email and SMS. Where most AI SDRs shine on the first response, Conversica's strength is the long game: engaging leads that don't convert immediately and maintaining contact over days and weeks until they're ready to talk to sales. For a machine shop, that maps well to long-cycle manufacturing deals, where an engineer who downloaded a capabilities guide in March might not issue an RFQ until June. Reviewers note Conversica is better suited to activating large lead databases than real-time website engagement. If your challenge is following up with hundreds of trade show leads, downloaded spec sheets, or quote requests that went cold, that's their sweet spot. Conversica integrates with Salesforce, HubSpot, Marketo, Pardot, and Dynamics, and pricing is custom (enterprise), with one roundup citing $1,500/month as a starting point. It's a mature product with a long track record, though it's an add-on to your stack rather than a full growth partner.

Best for: Mid-market and enterprise teams with large lead databases that need persistent nurture.

The right pick depends on where your shop is losing deals. If RFQs go unanswered overnight or on weekends, faster follow-up is your biggest lever, and a sub-60-second AI response is what Worqd is built around, along with the ads, creative, and pipeline recovery that feed it. If you're an enterprise operation already on Salesforce with heavy site traffic, Qualified's Piper is a strong fit. AiSDR and Apollo.io handle the outbound side, finding new OEM accounts and running sequences at prices a smaller shop can absorb. Conversica earns its keep when you have thousands of dormant leads that need patient, persistent follow-up. Whatever you choose, the principle from the research is consistent: responding within five minutes makes you dramatically more likely to qualify a lead, and 35-50% of sales go to the vendor that responds first. For most machine shops, that means the cheapest growth move isn't more ads. It's answering the inquiries you already get, faster. Book a free growth call with Worqd to find your bottleneck and get a plan for more demand, faster follow-up, and better creative.
