The short version

  • Each has a real cost: Device Magic neither plan publishes a price and both carry a three user minimum billed annually, so a two-person business cannot buy it at all and a small firm cannot benchmark the quote against published competitors; Postscript carrier pass-through fees are billed on top of the per-message rate, roughly $0.00418 per SMS and $0.00841 per MMS in the United States, and are routinely missing from the cost comparisons buyers build.
  • They diverge on capability: Device Magic covers Fully offline capture, Postscript covers Shopify segmentation.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Device Magic

  • Neither plan publishes a price and both carry a three user minimum billed annually, so a two-person business cannot buy it at all and a small firm cannot benchmark the quote against published competitors
  • Device Magic is now part of GoCanvas, which sells an overlapping mobile forms product, so buyers should ask directly about long-term investment in Device Magic before signing a multi-year term
  • Per user per month pricing means seasonal and occasional field staff consume full seats, and businesses with a large casual crew pay for licences that are used a few weeks a year
  • It captures and delivers data but does not manage the work itself, so there is no job costing, no scheduling depth and no invoicing, and it usually sits alongside a field service management system rather than replacing one
  • PDF layout control is the main reason to buy it and is also the most fiddly part of the product; complex certificate layouts take real configuration effort and are not something a field supervisor will maintain

Postscript

  • Carrier pass-through fees are billed on top of the per-message rate, roughly $0.00418 per SMS and $0.00841 per MMS in the United States, and are routinely missing from the cost comparisons buyers build.
  • The cheapest per-message rates require the $500 a month plan, so a small sender pays more than double the headline low rate per text.
  • The $0 Starter plan carries a $49 minimum monthly spend, so it is not a free tier and quiet months still generate a bill.
  • US SMS marketing carries real legal exposure under consent, quiet hours and carrier registration rules, and the compliance obligation sits with the merchant, not the platform.
  • It is SMS and MMS only, so email, push and on-site messaging live in a separate tool and audience suppression between the two has to be managed across systems.

Answered from the vendors’ own pages

Device Magic: What does Device Magic cost?

It does not publish prices. Both the Max and Enterprise plans are per user per month billed annually with a three user minimum, and you get a figure from sales.

Postscript: Is Postscript only for Shopify?

It is built for Shopify and that is where its segmentation advantage lies, but headless and non-Shopify stores are supported through an SDK with more setup work.

Device Magic: Who owns Device Magic?

It is part of GoCanvas, which also sells a competing mobile forms product.

Postscript: What is the real cost per text?

The plan rate plus carrier fees. On Starter that is about $0.015 plus roughly $0.00418 in US carrier fees per SMS, so budget close to two cents a message before discounts.

Device Magic: Does it work with no signal?

Yes, that is the main use case. Forms and reference data are held on the device and submissions sync when connectivity returns.

Postscript: Is the Starter plan free?

No. The base fee is $0 but there is a $49 minimum monthly spend, so it functions as a $49 floor.

Device Magic: Is there a submission limit?

No. Both plans list unlimited forms, unlimited submissions and unlimited lifetime data storage, so the cost variable is seats.

Postscript: Do I need a contract?

No. Contracts are offered but not required, and plans can be moved up or down at any time under usage-based billing.
