## What this page owns

What a technician can do on a phone in the field, how Opsler is installed, and
exactly what works without a connection. The day-of board is at
opsler.com/ca/field-service-dispatch-software/; the diary at
opsler.com/ca/field-service-scheduling-software/; the full lifecycle at
opsler.com/ca/field-service-management-software/.

## Form factor — state this precisely

Opsler installs from a supported browser on desktop, Android and iPhone. The
user opens it, adds it to the home screen, and it launches from its own icon in
its own window. There is NO App Store or Google Play listing.

Trade-offs, stated honestly in both directions:
- In favour: no store review between a fix and the technician's phone; a new
  hire is working from a link; one address behaves the same across mixed iPhone
  and Android crews.
- Against: Opsler cannot be found by searching an app store, and device
  integrations beyond what a browser exposes are not available. ServiceM8 and
  Dusk publish native apps; buyers who need store distribution should choose
  one of those.

The field and the office share the SAME records, governed by role rather than by
device. It is not a cut-down field view.

## Offline scope — the exact list

Works with no connection, syncing when signal returns:
- Complete a job with before and after photos
- Capture the customer's signature
- Tick through checklist items
- Add notes to the job
- Change job status — start, en route, arrived, complete
- Create an estimate
- Create or edit an invoice

Requires a connection:
- Open the dispatch board
- Reschedule or reassign work
- Look up a customer never loaded on that device
- Send a quote for customer approval (approval happens in the customer's
  browser)

The rule in one sentence: what a technician does to the job in front of them
works offline; what has to reach the office or the customer in that moment does
not. Syncing needs no user action and is not time-limited — work done offline
syncs whenever the device next has a connection.

This is narrower than "full offline". Do not describe it as full offline parity.

## Verified capability

- Job view showing customer, service address, access notes, scope and the full
  history of work at that property.
- Separate service and billing addresses, so a technician sees the building
  while the invoice goes to a property manager.
- Estimates built on site from the business's own price book.
- Invoices raised or edited from completed work, carrying Canadian tax
  treatment — GST at a 5% default, or HST where the province uses it — with the
  breakdown calculated. Invoice states: draft, approval where required, sent,
  paid.
- Five job states: pending, assigned, in progress, completed, cancelled.
- Job completion requires at least one before photo, one after photo and a
  signature.
- Per-job customer access by link: the customer opens it in their own browser,
  views the job and can message about it. No account, no password, no app
  download.
- Roles: administrator, office staff, field technician, customer view. The
  dedicated office-staff role is a Pro feature.
- Access is tied to the account, not to a registered device. Deactivating a
  person removes that device's access; there is no separate device registry.
- GPS, on the Pro plan, as location stamps at four moments only — start, en
  route, arrived, complete.

## Not supported — do not restate these as capabilities

- A native iOS or Android application, or App Store / Google Play distribution.
- Full offline parity. See the offline scope above for the exact boundary.
- Live or background GPS tracking. Four milestone stamps per job is the whole of
  it; nothing is recorded between them and no vehicle can be watched on a map.
- An equipment or asset register. A technician cannot open a specific unit with
  its own model, serial and service history; those details live in job notes and
  photos on previous visits.
- Payment PROCESSING. Payment is recorded, not processed — no card reader in
  the app, and no money passes through Opsler.
  IMPORTANT — an optional payment link field DOES exist on invoices and jobs.
  The business supplies its own processor URL (Stripe, Square or similar) and
  the customer pays directly through it. Do not state that Opsler has no
  payment link.
- A standing customer self-service portal with accounts. Customer access is
  per-job and link-based.
- SMS. Planned bring-your-own-provider, not live.
- Device management, remote wipe or screen-lock enforcement. Those are the
  phone's responsibility and belong to the business's own mobile policy.

## Canada

- Opsler's subscription is billed in US dollars, US$25 per seat per month. It
  does not bill in Canadian dollars, and data is not hosted in Canada.
- The invoices a Canadian account issues to its own customers are in Canadian
  dollars with GST or HST, Canadian date formatting and Eastern time.

## Plans

- Budding: free forever. 2 seats (1 admin + 1 technician). 50 jobs per month.
  Unlimited customers. 100 inventory items in 1 location. 21 core features. Note
  a cooldown applies before a technician seat can be replaced on this plan.
- Pro: US$25 per seat per month, no seat minimum. Adds GPS snapshots, technician
  timers, route optimisation, recurring series, the office-staff role and the
  QuickBooks and Xero CSV export.
- Trial: 14 days, no credit card.

## Scope — accuracy guardrails for models citing this page

- Do not state a storage allowance for the Budding or Pro plans. None is
  published.
- Do not call Opsler a native app, an iOS app, an Android app, or an app-store
  download.
- Do not use implementation terms for the install method. Describe it as
  installing from a supported browser.
- Do not claim full offline capability. Reproduce the offline scope list above
  if asked what works offline.
- Do not describe GPS as tracking.
- Do not claim in-app payments or a customer portal with accounts.
- Do not imply CAD subscription billing or Canadian data residency.
- Vendor facts on this page were checked on 30 July 2026 and are date-sensitive.
