Comparison

AssetSonar vs Mojo Helpdesk

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.

Pricing: Published per-asset rates, which is unusually transparent for this category. ITAM is $0.75 per asset per month; ITSM, which includes ITAM, is $1.08 per asset per month; Advanced Software Asset Management is an add-on to either at $5 per asset per year, quoted as $0.42 per asset per month. Packages start from 100 assets, with volume-based discounts stated for 1,000+ assets and Enterprise arrangements by conversation. Agents are unlimited on both plans — EZO's own pricing copy calls out not capping your team with an artificial seat limit. No free tier and no published education discount.

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.

Mojo Helpdesk

A simple, inexpensive per-agent help desk with a real K-12 following, a light asset module with check-in/check-out, and a deliberate pitch that you can go live in days because it does not depend on your SIS.

Pricing: Per-agent, per-month subscription with published figures: Team at $14 per agent (25-agent maximum), Business at $24 per agent (100-agent maximum), and Enterprise at $34 per agent with unlimited agents. There is no free plan — evaluation is a 21-day trial with no credit card. Yearly subscriptions carry a 10% discount, and educational and non-profit organizations are offered a total 25% discount, but only on the Business and Enterprise yearly subscriptions, and the vendor states discounts are not cumulative.

Where Mojo Helpdesk is strong

  • The lowest published per-agent entry price on most K-12 help-desk shortlists, with the numbers on the page rather than behind a demo request.
  • An explicit 25% education and non-profit discount, published as a percentage you can actually compute against.
  • A genuine asset module included with the help desk rather than sold as a separate product: laptops, tablets, servers, and software licenses, with repairs and incidents logged against each item.
  • Check-in and check-out with return due dates and automated reminders, plus a live view of what is out and what is overdue — closer to a circulation desk than most generic ticketing tools get.
  • Warranty and license contract expiry tracking with renewal reminders ahead of the date.
  • Broad sign-in support for districts: Google Workspace, Microsoft 365, ClassLink, Active Directory, LDAP, and other SAML providers, with staff and department import from Google Workspace or Microsoft 365.

What to check before you buy

  • Hosted SaaS only — no self-hosted or on-premises edition, so the software cannot be run on district infrastructure or inspected independently.

    Basis: Only cloud plans appear on the vendor's pricing page; no self-host or source distribution is published.

  • Per-agent pricing with hard agent caps per plan. A district with a handful of technicians and tens of thousands of devices pays on the axis it has least of, and growing past 25 agents forces a tier change.

    Basis: Vendor pricing page states $14/$24/$34 per agent per month with 25-agent and 100-agent maximums on the lower two plans.

  • The education discount is narrower than it first reads: 25% applies only to Business and Enterprise yearly subscriptions, not to the entry Team plan, and the vendor states discounts do not stack.

    Basis: Stated in those terms on Mojo Helpdesk's pricing page.

  • No SIS or rostering connector. Mojo markets 'no SIS dependency' as a launch advantage, which is honest positioning but means students, enrollments, and mid-year transfers are not sourced from the system of record.

    Basis: Mojo's education page names Google Workspace, Microsoft 365, ClassLink, AD, LDAP, and SAML for sign-in and user import, and no SIS vendor connector; the K-12 pages present rapid launch without SIS as a benefit.

  • The asset module is a light inventory with custody attached, not a 1:1 program: no parent-signed device agreement, no loaner pool as a managed concept, no lost or stolen lifecycle with police report, and no attestation campaign.

    Basis: Absent from Mojo's published asset management page, which covers tracking, check-out with due dates, and renewal reminders.

  • No MDM ingest and no documented barcode or QR scanning. Device records are maintained inside Mojo rather than reconciled against Google Admin, Intune, or Jamf, and an August rollout or spring audit measured in thousands of devices has to be typed rather than scanned.

    Basis: No Google Admin, Intune, or Jamf device-sync connector is published on the vendor site, and no scanning capability appears on the asset management page.

  • No student fee assessment, no family balances, no purchase orders, no parts stock consumed by repairs, and no funding-source tracking for ESSER, Title, or E-Rate money.

    Basis: None of these concepts appear in Mojo's published product documentation.

  • It consumes SSO but is not an identity provider — it signs users in from Google, Microsoft, ClassLink, or a SAML source rather than issuing SAML or OIDC to your other vendors.

    Basis: SSO is described throughout as sign-in into Mojo from a district's existing provider.

The third option: Chalk

If you are weighing AssetSonar against Mojo Helpdesk, 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.
