Postscript Pricing for Shopify: Starter, Growth and Professional

What each Postscript plan charges

Postscript’s public price card lists these base fees and sending rates. Compare the same country, sender and billed units. The platform rate is only one line of the invoice.

Check the Starter floor using Postscript’s usage billing instructions and the quote for your account. Ask how the minimum appears on a quiet invoice and which charges count toward it. The pricing page lists the carrier line separately. Get both in the same example so you can see what you would actually pay.

When the message mix changes the cheaper plan

The difference between Starter and Growth is a tenth of a cent on each listed SMS unit, but one and a half cents on each listed MMS unit. That makes the MMS mix worth checking even when the list size and the SMS count barely move.

The second row changes only the MMS units. At the listed rates, Growth is $40 higher on the all-SMS row and $5 lower on the mixed row. That is a calculation from the displayed platform fees and usage rates. Carrier charges, special rates and other services belong on separate lines.

For SMS alone, the difference in the listed SMS rates offsets the $100 Growth fee at 100,000 billed SMS units under the same assumptions. Above that, Growth has the lower platform-and-SMS subtotal. If you pay a different rate, or need one of Growth’s features regardless of volume, use your actual quote.

When it’s worth moving up a plan

If you only send SMS, the rate on Growth makes up its $100 monthly fee at 100,000 billed SMS units under the listed rates. Professional starts with another $400 in platform fees and reduces the SMS rate by another $0.001. The second step therefore needs four times the SMS volume to pay for itself on rate alone.

These are SMS-only comparisons for the same traffic, before separate charges. If you send MMS, the mix changes the answer. If you need Professional’s documented API access or priority support, price that work too. A cheaper invoice is a poor reason to choose a plan if you still need to buy the missing work elsewhere.

Postscript’s invoice guide says Starter and Growth shops are charged for usage as they reach their billing threshold. It describes a monthly charge for Professional and Enterprise. Ask for the full billing-period total and how many charges would show on your statement. The number of transactions and the cost of the month answer different questions.

Use a normal month and a promotion month

Pull one ordinary month and a month with heavy promotions. For each, get the billed SMS units and MMS units, the destination markets and the sending number. Bring one short reminder and one promotion with its real link and personalization. Ask to see where the bill would change if the longer message becomes multiple units.

Postscript says carrier fees appear on their own line. Keep that line visible across quotes. If your proposal adds a dedicated short code, premium features or another product, list those separately too. The pricing FAQ describes a first-30-day trial credit. Run a normal recurring month alongside it so the trial doesn’t decide your annual budget.

Then compare the quotes at your actual volumes. Ask for the line that would change if you moved a promotion from SMS to MMS, paused it midway or dropped back to an ordinary send month. If a vendor can show those changes from the same events, you have a quote you can reconcile.

Decide who will answer after the send

Price the platform you need to run the campaign. Then put a real shopper question in the demo, such as whether an order placed today can arrive by Friday. Decide who can answer from store policy, who can take over when the answer needs a person, and which tools they will use.
