Comparison
AssetSonar vs Sortly
Two tools districts shortlist for device tracking and IT operations, compared the way a buying committee actually reads them: what each is, what each does well, and what to check before signing. We build Chalk, a third option in this space — that context is worth knowing as you read, and it is why every claim below carries its basis.
AssetSonar
EZO's IT-asset product, and the rare asset tracker that publishes a per-asset price and includes a genuine service desk at the higher tier — metered by the one number a 1:1 district has most of.
Where AssetSonar is strong
- It publishes real per-asset prices instead of gating every number behind a demo — $0.75 per asset per month for ITAM and $1.08 for ITSM — which makes a district budget line something you can build without a sales call.
- Unlimited agents on both plans, so adding technicians, building secretaries or a summer help-desk aide never changes the bill.
- The ITSM tier is a real service desk, not a ticket list: request and incident management, problem and change management, a service catalog, multi-channel intake, automated routing, multi-step approvals, SLA policies with business hours and escalation, a knowledge base and a self-service portal.
- Custody features deeper than most trackers — check-in and check-out, automatic checkouts, automatic custody transfer, reservations and an availability calendar.
- Genuine discovery breadth for a commercial tracker: agent-based discovery, network discovery, MDM integrations, barcode and QR scanning, and RFID tagging.
- Procurement and service done properly — purchase orders and requests with multi-tier approvals, vendor management, warranty integration, service triage, and scheduled and recurring maintenance with automated reminders.
What to check before you buy
The meter is your fleet. At a per-asset rate, a 1:1 district is billed on the number it has most of, and every Chromebook you add is a line item forever.
Basis: Vendor pricing page quotes ITAM and ITSM as per-asset-per-month rates.
Packages start at 100 assets, so the smallest sites pay a floor rather than what they use.
Basis: Vendor pricing FAQ: AssetSonar packages start from 100 assets, with volume-based discounts for higher volumes.
The help desk is the upgrade. SLA management, the service catalog, the self-service portal, the knowledge base, problem and change management and the CMDB are all marked ITSM-only in the vendor's own comparison table — the difference between $0.75 and $1.08 per asset per month.
Basis: Vendor's published ITAM-versus-ITSM plan comparison table.
Software asset management is a third line item on top of either plan, at $5 per asset per year.
Basis: Vendor pricing FAQ describes Advanced SAM as an add-on available with both ITAM and ITSM plans.
No SIS or rostering integration — no OneRoster, Clever, ClassLink, PowerSchool, Infinite Campus or Skyward anywhere in EZO's connector catalog, which covers MDM, identity and procurement systems.
Basis: Absent from EZO's published integrations listing for AssetSonar.
No student, guardian or enrollment concepts. Checkout is employee custody, so a transfer, a withdrawal or grade rollover is invisible unless someone edits the record.
Basis: The product's data model tracks assets and users; the custody features are documented as employee check-in and checkout.
No parent e-signature on a device agreement, no student fee assessment, no family balances, and no funding-source or grant dimension for ESSER, Title or E-Rate reporting.
Basis: Absent from EZO's documented feature set and plan comparison.
Device connectors are ingest-oriented. The MDM integrations import device state into AssetSonar; nothing pushes a reviewed set of changes back, so an OU move or disabling a stolen Chromebook stays manual in Google Admin.
Basis: EZO's integration listing describes MDM connectors as importing device data, with no write-back workflow claimed.
Sortly
The friendliest inventory app in this comparison and the easiest to actually start using — built for supply closets and job sites, priced by how many items you have, which is exactly the wrong meter for a 1:1 fleet.
Where Sortly is strong
- Every price is on the page, including a genuinely free tier, with no demo gate anywhere in the funnel.
- The lowest adoption cost in this comparison by a distance: folders, tags, photos and custom fields, usable by a building secretary in an afternoon without an IT project behind it.
- Strong mobile — iOS and Android with offline access, barcode and QR scanning, and label generation from inside the same app, so counting is a phone job rather than a scanner-hardware purchase.
- Alerting that fits consumables well: low stock alerts for reordering and date-based alerts for maintenance and repair schedules, with in-app and email notification.
- More reporting than the price suggests — activity history, inventory summaries, user activity, low stock and item-flow reports, saved custom reports, and report subscriptions delivered on a schedule.
- Real integration surface for a product this simple: webhooks, an API, QuickBooks Online, and Slack and Microsoft Teams notifications, plus purchase orders, pick lists, and check-in and check-out.
What to check before you buy
Pricing meters unique items, and a 1:1 district's item count is its student count. At 5,000 items the published tier is $299 per month, and anything past 10,000 items is Enterprise quote-only — a mid-sized district is off the published ladder on device count alone.
Basis: Vendor pricing page item limits: 100 free, 500 Advanced, 2,000 Ultra, 5,000 Premium, 10,000+ Enterprise.
User licenses are metered too, and tightly: 1 user free, 2 on Advanced, 5 on Ultra, 8 on Premium. A technician team plus building staff crosses into Enterprise quickly.
Basis: Vendor pricing page user-license limits per tier.
No help desk or ticketing of any kind. A district running Sortly still buys a service desk somewhere else, and the two never see each other.
Basis: Absent from the vendor's published feature list, which covers inventory, alerts, reporting and integrations.
No MDM or device integrations at all. The published integration list is QuickBooks Online, Slack, Microsoft Teams, webhooks and an API — so ChromeOS, Intune and Jamf data is typed or imported, and serials go stale between imports.
Basis: Vendor features page lists no device-management or directory connectors.
No SIS or rostering integration and no student, guardian or enrollment concepts — nothing notices a transfer, a withdrawal or grade rollover.
Basis: Absent from the vendor's feature list and from its industry positioning, which addresses inventory rather than student records.
Check-in and check-out is item custody, not a school-year loan: no due dates on a student device agreement, no e-signature, no damage fee, no family balance and no loaner pool workflow.
Basis: Vendor documents check-in/check-out alongside pick lists and stock tracking, with no agreement or fee concepts published.
It is an inventory product rather than an IT asset lifecycle product — warranty expiry, depreciation, ChromeOS auto-update expiration and refresh planning are not in the published feature set, though generic date-based alerts can approximate some of it.
Basis: Vendor features page covers custom fields, alerts and reports; no warranty, depreciation or lifecycle module is published.
Hosted SaaS only, with no self-hosted option, and no SSO or SAML in the published feature list — so it sits outside your single sign-on estate in both directions.
Basis: No self-host or source distribution is offered on the vendor site, and SSO does not appear on the features or pricing pages.
The third option: Chalk
If you are weighing AssetSonar against Sortly, Chalk belongs on the same shortlist. It is the open-source K-12 IT stack: device inventory that fills itself in from Google Admin, Intune, and Jamf against a roster synced from your SIS, a 1:1 circulation desk with agreements and fees, repairs with parts and costs, a help desk that already knows who is asking, and a built-in SAML/OIDC identity provider.
- Self-host it free forever under AGPL-3.0 — the entire feature set, one binary, your infrastructure — or use the hosted version, priced by fleet size with no per-seat or per-student fees and the price ladder published.
- Built only for K-12: students, buildings, custody, funding sources, and ChromeOS auto-update expiration are native concepts, not custom fields.
- Writes back to Google Admin as a reviewed diff — every OU move, disable, and deprovision previewed before it executes — and serves a OneRoster 1.1 API so other district systems can pull the roster from Chalk.
- Fees are assessed and tracked without touching payment cards, keeping the asset system out of your PCI scope.
See all three on your own roster.
Chalk installs to a populated inventory in about 30 minutes. Self-host free under AGPL-3.0, or let us run it — priced by fleet size, never per seat.
