Chalk

Comparison

EZOfficeInventory vs Reftab

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.

EZOfficeInventory

A capable commercial asset tracker with the deepest MDM connector list in its class — and, like the rest of that class, no roster, no student, and no write-back.

Pricing: Subscription priced per tracked item, quoted from an item-count slider across published Essential, Advanced, and Premium tiers, with Enterprise quote-only. Users are advertised as unlimited, subject to a fair-use asterisk, so the meter is your fleet rather than your staff. There is no free tier — only a time-limited trial. EZO's IT-asset variant, AssetSonar, is a separate product priced per asset per month, with ITSM ticketing sold as a higher per-asset rate and advanced software asset management as a further add-on. EZO's dedicated K-12 landing page is no longer live, and no education discount is published.

Where EZOfficeInventory is strong

  • The deepest device-ingest integration list of the commercial asset trackers — Intune, Jamf Pro, Kandji, Mosyle, SCCM, Workspace ONE, JumpCloud, Meraki, Apple Business Manager, and Google Endpoint Management for ChromeOS.
  • Warranty details sync automatically from manufacturers including Dell and Lenovo, and procurement data can sync from CDW — genuinely less manual data entry than most.
  • Native iOS and Android apps with barcode and QR scanning, on every tier.
  • Real checkout, reservation, and audit workflows, with custom fields, purchase orders, and RFID support at the middle tier.
  • Unlimited users at every tier, so adding technicians or building staff does not change the bill.
  • AssetSonar's ITSM tier includes genuine ticketing with SLA management, a knowledge base, and a service catalog — the only product in this asset-tracker group with native SLAs.

What to check before you buy

  • The base product has no ticketing at all. Native help desk with SLAs exists only in AssetSonar's ITSM tier — a different product at a higher per-asset rate — so a district gets either the asset tracker or a second contract.

    Basis: EZOfficeInventory offers Jira and Zendesk connectors rather than native ticketing; SLA management appears in AssetSonar's ITSM pricing tier.

  • No SIS or rostering integration — no OneRoster, Clever, ClassLink, or PowerSchool anywhere in the connector catalog. Students arrive by CSV.

    Basis: None appear in EZO's full published integration list, which covers MDM, identity, and procurement systems only.

  • No student, guardian, or family concepts, and therefore nothing that notices a transfer, a withdrawal, or grade rollover.

    Basis: Absent from the product's data model, which tracks items and users.

  • No parent e-signature on a device agreement, no student fee assessment, and no family balances.

    Basis: Absent from EZO's documented feature set.

  • No funding-source or grant tracking for ESSER, Title, or E-Rate reporting.

    Basis: No funding-source dimension appears in the product documentation.

  • ChromeOS support is import only. The Google Endpoint Management connector is described as importing ChromeOS and mobile data; nothing writes back, so OU moves and disabling a stolen Chromebook stay manual in Google Admin.

    Basis: EZO's integration listing describes the connector as importing ChromeOS and mobile data into AssetSonar, with no write-back claimed.

  • It consumes SSO but is not an identity provider — Entra ID, Okta with SCIM, OneLogin, and Ping are identity sources it reads, not identity it issues.

    Basis: EZO's identity integrations are configured as a service provider against an external IdP.

  • Maintenance is a separate paid CMMS add-on even on the top tier, so repairs that draw parts out of stock are not simply included.

    Basis: EZO CMMS is listed as an add-on alongside the Premium tier and sold as its own product.

Reftab

A well-designed asset tracker with a real free-forever tier, self-serve signup, and no sales call — and, like the rest of its class, no help desk, no roster, and no student.

Pricing: Subscription metered per asset, with unlimited platform users on every tier and an annual-billing discount. There is a genuine free-forever tier capped at a small asset count that still includes unlimited custom fields and locations, reservations, mobile apps, barcodes, and check-in/check-out. Paid tiers add capability in layers: SSO and two-factor at the entry paid tier, signature capture and consumables above it, and the MDM, vendor, and identity-provisioning integrations only at the top tier. Software management is priced separately per tracked user. Signup is self-serve with no demo gate. The pricing FAQ raises the question of education and nonprofit discounts; we could not read the answer, so ask them directly.

Where Reftab is strong

  • The only genuinely free-forever tier in this comparison, and a generous one — unlimited custom fields and locations, reservations with calendars, advanced reports with export, mobile apps, and barcode check-in/check-out at no cost.
  • SSO and two-factor authentication at the lowest paid tier rather than gated to enterprise, which is unusual and district-friendly.
  • Unlimited platform users on every tier, so the bill never grows because you added staff.
  • Native iOS and Android apps with barcode scanning, plus a barcode designer and custom email templates.
  • Strong MDM breadth at the top tier — Intune, Jamf Pro and Jamf School, Kandji, Mosyle, NinjaOne, FleetDM, and Apple Business Manager — plus vendor warranty sync from Dell, CDW, Lenovo, and Apple.
  • A Google Workspace integration that imports Chromebooks and mobile devices daily, with configurable field mapping and optional auto-assignment to the Google-assigned user.

What to check before you buy

  • No native help desk or ticketing with SLAs. Jira Cloud and Zendesk connectors exist to surface assets on someone else's ticket, and they are top-tier features — so a district buys a service desk separately either way.

    Basis: Reftab's integration listing offers Jira and Zendesk plugins rather than native ticketing; no SLA capability appears in any tier.

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

    Basis: None appear in Reftab's integration catalog or documentation; the identity integrations are corporate directories.

  • Signature capture is staff-side custody acknowledgement, not a parent or guardian e-signature on a device agreement, and it sits behind a mid-tier upgrade.

    Basis: Reftab lists signature capture as a Pro-tier feature; no guardian entity or agreement workflow exists in the data model.

  • No student fee assessment and no family balances, so damage recovered at collection time is tracked outside the system.

    Basis: Absent from Reftab's documented feature set across all tiers.

  • No funding-source or grant tracking for ESSER, Title, or E-Rate attribution.

    Basis: No funding-source dimension appears in Reftab's documentation.

  • ChromeOS support is import only and syncs once daily. Nothing writes back, so OU moves and disabling a stolen Chromebook remain manual work in Google Admin.

    Basis: Reftab's Google Workspace integration guide documents a daily one-way import with field mapping; no write-back is described.

  • The MDM connectors that make the inventory self-maintaining — Intune, Jamf, Kandji, Mosyle, Apple Business Manager — are all top-tier features, which is a meaningful jump from the tier where SSO lives.

    Basis: Reftab's pricing page places all MDM, vendor, and IdP integrations at the Business tier.

  • It consumes SSO but is not an identity provider. Okta, Entra ID, SAML 2.0, SCIM, and LDAP are identity it reads, not identity it issues — and the IdP user-provisioning integrations are top-tier only.

    Basis: Reftab is configured as a service provider against an external IdP; provisioning integrations are listed at the Business tier.

The third option: Chalk

If you are weighing EZOfficeInventory against Reftab, 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.
