From Shopify (or Shopify Plus)
You can sit alongside Shopify (recommended) or replace the checkout layer entirely. Most brands keep Shopify as the product catalog + storefront, and run GrowthFlowLine for checkout, payments, CRM, and subscriptions.
- Products + variants: one-way sync, hourly. We do not duplicate inventory.
- Customers + addresses: full import on day 1. Deduped by email.
- Historical orders: 24-month default. Older on request.
- Discount codes + tax rules: one-click import.
From Recharge
This is the hairiest piece — recurring tokens, retry schedules, customer portal links. Our migration team has done this 400+ times. The short version:
- We re-tokenize subscriptions on your new processor without re-prompting shoppers (vault-to-vault transfer where supported, OAuth re-auth where not).
- Existing renewal dates are preserved to the day. Dunning state is preserved (retry count, last failure code).
- Customer-portal URLs from Recharge redirect to your new portal for 90 days.
- No re-billing customers during the cutover window. We freeze billing on Friday, cut over Saturday, resume Monday.
From Gorgias (or Zendesk / Front)
Conversation history imports cleanly. Macros and rules get mapped to our equivalents — we'll review every one with your CS lead. Channel re-connection (Gmail, SMS, IG, chat) is a 30-minute task per channel.
Stripe-only setups
If you're running Stripe Checkout or Stripe Payment Element today, we connect your Stripe account directly. No data leaves Stripe — you keep the same merchant ID, the same payouts, the same dashboard. We add routing, dunning, and the rest of the platform on top.
Custom builds
If your checkout / subs / CS layer is custom-built, our solutions team will scope a 2-3 week migration project at no cost. Most custom builds reuse 80%+ of their existing storefront and product data — we layer the GrowthFlowLine engine underneath.
A typical timeline
- Week 0 Kickoff call. Scope, map fields, decide cutover window.
- Week 1 Data import (products, customers, orders, subs). Staging workspace is live.
- Week 2 Checkout build + A/B test against current. Processors connected. CS macros migrated.
- Cutover Friday evening: billing frozen. Saturday: DNS / iframe swap. Monday: live, supported.
- Week 3 Daily check-in. Tuning routing, dunning, automations. Decommission old apps.
Our migration team
Every migration gets one solutions engineer + one CS lead, working in your Slack from kickoff to 30 days post-cutover. No tickets, no hand-offs. Free on every plan.
