What's the real implementation timeline for Skio on a $10M-$30M GMV Shopify Plus brand with an existing subscriber base to migrate?

Where do the 60 to 90 days actually go?

The 60 to 90 days go to six overlapping phases, and Skio's own steps fill only the middle of them. Merchants report that range for subscription migrations in general (Deploi Build vs. Buy, July 2026 research); the phase timings are Deploi's planning judgment for a Plus brand at $10 million to $30 million. Each phase needs its full time, because rushing one raises the subscriber-loss risk of moving onto Skio.

Why is Skio's 4 to 5 weeks not the project timeline?

Skio's 4 to 5 weeks is not the project timeline because it starts when your prerequisites are done and ends when the data moves. Skio says merchants hear from its Migrations team within 3 to 5 business days of finishing the prerequisites. The whole integration and migration then takes 4 to 5 weeks, with buffers for your team's review (Skio Help Center, October 2026). The store must be live on Skio before Skio previews the existing subscriptions: at least 24 to 36 hours by its migrations guide (Skio Help Center), about 24 by its overview (Skio Help Center, October 2026). The data step itself typically takes 2 to 3 days (Skio Help Center, October 2026).

Skio's clock covers none of the vault work, the catalog freeze or the old app's removal. Skio's process also never bills the same subscriber from two platforms. The merchant stops the old platform's billing on migration day, and Skio holds billing for migrated subscriptions until that is confirmed (Skio Help Center, October 2026). Shopify "strongly recommend[s]" pausing billing in the old app while payment methods and contracts move, because pausing "helps you avoid double-billing a contract" (Shopify developer docs, October 2026).

What decides whether you land at 60 days or 90?

Four facts decide whether you land at 60 days or 90, and none of them is Skio's execution.

• Where the cards are vaulted. Cards held in a Stripe, Braintree or Authorize.net account, as on legacy Recharge or a store outside Shopify, move once the new store connects that account (Skio Help Center, Shopify Help Center, October 2026). Cards in Shopify's vault wait on Shopify's Professional Services migration, which a Plus store can use (Shopify Help Center, October 2026). In our judgment that one fact is worth two to four weeks; where each saved payment method sits in a store-to-store move has its own answer.
• Whether the catalog is frozen. Every product change during mapping is rework on a file someone filled in by hand.
• Whether the product page is in scope. Skio's team sets up its Plan Picker and matches your existing widget; other design or functional updates are out of its typical scope (Skio Help Center, October 2026). On a new theme, that gap is yours.
• How your billing dates spread. If most contracts bill in the first week of the month, plan around that week. Skio migrates early in the week, after that day's legacy billing has run (Skio Help Center, October 2026), so the date has to dodge your busiest billing days.

When does the timeline need to be longer, or split in two?

The timeline needs to be longer, or split into two projects, whenever the storefront is also moving. This is a platform timeline, not a replatform timeline, so a storefront move pushes the total past a single quarter.

Subscriber messages run on the same calendar: the four-message sequence keys two sends to the cutover and two to each subscriber's charge date.
