Nobody's Adding Up the Real Number
Most SDR managers know roughly what each tool costs. They just never add them up.
Apollo: "yeah, around $100 a seat." Instantly: "something like $60." ZoomInfo: "it's in the budget." The stack accretes over 18 months, each tool approved individually, and nobody runs the combined number until someone asks why sales software is eating half the budget.
So let's run it.
What Each Tool Actually Costs in 2026
Here's current pricing across the six tools that show up most often in SDR stacks:
Apollo
- Basic: $49/user/month
- Professional: $99/user/month
- Organization: $149/user/month
Apollo handles prospecting (contact database + email finder) and increasingly sequences. The most common SDR use: data enrichment + basic sequences, which puts most teams on Professional at $99/seat.
Instantly
- Growth: $30/seat/month
- Hypergrowth: $77.6/seat/month
- Light Speed: custom
Instantly is an email sending and sequencing tool. Strong for high-volume cold email. The Growth plan works for smaller teams; heavier users land on Hypergrowth.
Clay
- Explorer: $149/month (individual)
- Pro: $349/month
- Enterprise: custom
Clay is a data enrichment and automation platform. Unlike most tools it's not per-seat — you pay per credits/rows and a platform fee. The Pro plan at $349/mo covers most small-to-mid SDR teams.
Salesloft
- Essentials: $125/user/month
- Advanced: $150/user/month
- Premier: $165/user/month
Salesloft is a sales engagement platform — sequences, dialer, reporting. Enterprise teams run on this; it's full-featured and priced accordingly.
Outreach
- Standard: $100/user/month
- Professional: $130/user/month
- Enterprise: custom
Another full sales engagement platform, similar competitive tier to Salesloft. $100–$130/seat is the working range before enterprise volume discounts.
ZoomInfo
- Professional: ~$250/user/month
- Advanced: ~$400/user/month
- Elite: ~$500/user/month
ZoomInfo is a contact intelligence database. The per-seat cost is the most expensive line item in most stacks. The $250–$500 range is real — and billed annually, so it's often a lump sum that gets buried.

The Hidden Costs Nobody Puts in the Spreadsheet
Per-seat and per-month fees are just the visible layer. There are three cost categories that don't show up in vendor invoices:
Training and onboarding. Every new SDR needs to learn 3–5 tools, not one. Multi-tool stacks add 1–2 weeks to effective onboarding. At a fully-loaded rep cost of $6,000–$8,000/month, that's $3,000–$4,000 in delayed productivity per hire — recurring every time you backfill.
Integration maintenance. Each tool in the stack needs to talk to your CRM. ZoomInfo → Apollo → Salesloft → Salesforce is four integration points that each require maintenance when vendors push API changes. Most teams have either a RevOps person spending 10–20% of their time on this, or broken integrations they've accepted as normal.
Context switching. An SDR researching a prospect in ZoomInfo, enriching in Clay, sequencing in Outreach, and logging in Salesforce is switching contexts 4+ times per account. The cognitive overhead isn't free. Estimates for knowledge worker context switching costs put the productivity tax at 20–40% — that's hours of lost output per rep per week, priced at nothing in any vendor contract but real in pipeline output.
Data sync failures. Contact data goes stale. Enrichment doesn't propagate correctly. A sequence fires to a contact who already replied in a different tool. These failures are small individually and invisible in aggregate — but they compound into reputation damage (spam complaints) and missed pipeline (duplicate outreach, wrong contact data).
The Consolidation Alternative
Conveyor replaces the prospecting, enrichment, and outreach layer of the SDR stack in a single workflow.
$299/month flat. No per-seat pricing. No contracts. Apollo finds the prospect, Clay enriches them, Instantly sequences them — Conveyor does all three in one place.
For a 5-person SDR team on a mid-tier stack: $1,857/month drops to $299/month. That's $18,696/year back in budget.
For a 10-person team on an enterprise stack: the difference runs into six figures annually.
