How long a Shopify rebuild takes, and what the three weeks cover
About three weeks. Convey Growth put a coffee roaster on a new Shopify site in about three weeks, with 13 email flows built in 21 days, and installed an aircraft company's store in 21 days (Sep 17 to Oct 8, 2026), its fit selector built from 11,190 invoice lines. The old site stays up until the new one is proven.
The three weeks, in order.
Week one: access, the read, the baseline. Staff access to the store, the email platform and the ad accounts. Four weeks of the old store frozen as the baseline. The things costing orders written down, each with a number.
Week two: the build. The store rebuilt or fixed around the decision that stops someone buying. The flows written in the brand's voice. The board wired to the store's own record.
Week three: checked, then live. Every flow tested end to end before launch. The old site stays up until the new one is proven. The first read against the baseline comes at four weeks.
Two installs, dated.
| What | Value | Window |
|---|---|---|

| a coffee roaster: orders a day since launch | +98% | Jul 28 to Oct 12, 2026 |

| an aircraft company: fitment at launch | 55 airplanes fit, 21 more by photo | Oct 8, 2026 |
Observed results from the store's own record, not isolated causal lift.
What slows it down.
Access. Most lost days in week one are spent waiting on logins. Staff accounts on day one, for the store, the email platform and every ad account, save the most time.
Product data. Sizes, variants and fit that live in spreadsheets or old invoices take the longest to get right. The aircraft company's fit selector came from 11,190 invoice lines.
Decisions. One person who can say yes to copy and offers within a day keeps three weeks at three weeks.
Questions.
Does the whole site have to be rebuilt?
No. Sometimes the store gets fixed, not rebuilt. The free read decides which, from the five things costing orders.
Does the store go down during the switch?
No. The old site stays up until the new one is proven.
What happens after the three weeks?
The weekly rhythm: the board rebuilt every morning from the store's own record, the numbers in writing every Friday, and the first read against the baseline at four weeks.
