Comparison

AssetSonar vs AssetTiger

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.

AssetTiger

The cheapest per-asset tracker a district will find, with no feature gating and unlimited users — and no ticketing, no roster, and no way to see a Chromebook that did not arrive on a spreadsheet.

Pricing: Subscription metered purely on asset count across published tiers, with unlimited users on every paid plan and yearly billing discounted against monthly — the vendor's own framing is 'pay for assets, not seats.' Stock inventory is a separate small add-on. Note a correction to widely repeated third-party claims: the free plan is now a 30-day trial capped at 250 assets and two users, after which the account becomes view-only. It is not free forever. The pricing FAQ raises the question of school and nonprofit discounts; we could not read the answer, so ask them directly.

Where AssetTiger is strong

  • The lowest per-asset cost in this comparison by a wide margin, on a clean single meter.
  • No feature gating between paid tiers — the vendor states explicitly that you upgrade to track more assets, not to unlock capabilities. That is unusually honest packaging and worth conceding.
  • Unlimited users on every paid plan, so every building secretary and tech can have an account for free.
  • Native iOS and Android apps with barcode and QR scanning, plus label printing from any printer — from a company whose main business is asset tags.
  • Check-in and check-out with due dates and overdue alerts, which is more custody machinery than most trackers at this price.
  • Deep reporting for the category — a large library of report types and a very granular permission model.

What to check before you buy

  • No ticketing or help desk of any kind, and no connectors to one. A district running AssetTiger buys or keeps a separate service desk, and the two never see each other.

    Basis: No ticketing capability or integration appears anywhere in AssetTiger's feature list.

  • No MDM or device-management ingest at all — nothing pulls from Google Admin, Intune, or Jamf. Every Chromebook enters by CSV import or by hand, and nothing detects a device you did not know about.

    Basis: AssetTiger publishes no MDM connectors; this is the largest functional gap for a Chromebook district.

  • No SIS or rostering integration — no OneRoster, Clever, ClassLink, or PowerSchool — and no student, guardian, or family concepts. Nothing notices a transfer or a withdrawal.

    Basis: None appear in AssetTiger's features or integration documentation.

  • No parent e-signature on a device agreement and no student fee assessment or family balances, so damage at collection time is handled outside the system.

    Basis: Absent from AssetTiger's documented feature set.

  • Fund tracking exists, but it is generic budget allocation rather than grant-program aware — it will not produce the ESSER, Title, or E-Rate attribution an audit asks for without you building the structure by hand.

    Basis: AssetTiger lists a fund-tracking feature with a per-plan cap; no grant-program or funding-source-restriction concepts are documented.

  • The weakest identity story in this comparison: two-factor plus Google SSO only, with no evidence of SAML support, and certainly no ability to act as an identity provider itself.

    Basis: AssetTiger's feature list names 2FA and Google SSO; no SAML or OIDC support is documented.

  • The free plan is a 30-day trial, not a free tier. After it lapses the account is view-only, and it is limited to two users during the trial.

    Basis: AssetTiger's pricing table labels that column a free 30-day trial; third-party review sites still repeat a legacy free-forever claim that the vendor's page contradicts.

  • Stock inventory is a separate paid add-on, and there is no documented link between it and repair records, so consuming a part against a specific repair is not a supported workflow.

    Basis: Inventory is listed and priced as an add-on; no repair-to-parts linkage appears in the documentation.

The third option: Chalk

If you are weighing AssetSonar against AssetTiger, 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.
