Replatform to BigCommerce
Without Losing Rankings
or Revenue
Migration is the highest-risk operation in ecommerce. One bad cutover drops rankings and stalls revenue for weeks. We map every URL, test every integration, and rehearse your cutover before a single DNS record changes.
Moving from a specific platform? Jump to your migration guide:
Most migrations fail before launch day
SEO rankings crater when redirect maps are incomplete. Integrations break when nobody tested them on staging. Revenue stalls when a cutover stretches from hours into days.
Manual product exports that break halfway
Data validation runs after go-live, not before. Customers find broken records first.
URL structure wiped out on launch day
Organic rankings drop 30 to 50% because 301 maps were incomplete or untested.
Integrations reconnected weeks after launch
ERP, 3PL, and PIM reconnections are treated as post-launch tasks. Inventory gaps follow.
4 to 8 hours of downtime on go-live weekend
A hard cutover with no rollback plan means every minute of downtime costs real revenue.
No fixed go-live date from day one
Scope creep extends a 60-day project to 6 months with no accountability milestone.
Automated migration with integrity reports before data moves
Every record counted, compared, and verified on staging. Zero deltas allowed through to cutover.
Full URL mapping and 301 redirects deployed before cutover
Every legacy URL maps to its BigCommerce equivalent. Your SEO equity holds on day one.
All integrations tested on staging before a single line goes live
ERP, PIM, 3PL, Klaviyo, and payment gateways validated in parallel with the build.
Rehearsed cutover with a 15-minute rollback window
Your go-live runs like a controlled deployment, not a leap of faith. We have run this before.
Fixed 45-day sprint with a contractual go-live date
Daily progress updates. Scope locked before build begins. Launch date committed on day one.
From Discovery Call to Live BigCommerce Store in 45 Days
Five structured phases, one fixed launch date. Every URL mapped, every integration tested, every cutover rehearsed before your store goes live.
We scope your current platform, map integrations, count data volumes, and rate complexity.
We map every URL to its BigCommerce equivalent. You sign off the 301 plan before build.
We rebuild your theme, custom functions, and every integration on staging in parallel sprints.
We run full checkout, search, speed, and integration QA. Your team gives final UAT sign-off.
We run the final data sync and DNS cutover. Then 30 days of post-launch monitoring begins.
| Legacy URL | New URL | Status |
|---|---|---|
| /collections/jackets | /outerwear/jackets | 301 |
| /products/wool-coat | /outerwear/jackets/wool-coat | 301 |
| /pages/size-guide | /size-guide | 301 |
| /blogs/news/* | /blog/* | 301 |
Every layer of your store, moved and accounted for
A replatform is more than moving products. It covers your catalog, orders, customer history, integrations, SEO equity, and custom logic. We handle all of it.
Complete data migration
We move products, variants, images, orders, customers, reviews, and gift card balances. Counted in, counted out. You get an integrity report before cutover, so no order or record goes missing.
SEO equity preservation
We map every indexed URL to its BigCommerce equivalent. You approve the 301 plan before a single page moves to staging.
Integration reconnection
We reconnect ERP, PIM, 3PL, Klaviyo, payment gateways, and review platforms. Each one is tested on staging before we confirm your cutover date.
Theme migration and custom development
We rebuild your front end natively in BigCommerce Stencil or a headless stack. Custom functions, checkout scripts, and storefront logic move over with full test coverage. Your store keeps every feature customers rely on.
- Stencil or headless (Next.js)
- Custom checkout scripts transferred
- Mobile-first performance benchmarks
- Full code handover with documentation
30-day post-launch monitoring
We run daily error reports, search console checks, and integration health checks for 30 days after launch. Issues get fixed fast, so early revenue stays protected.
Scoped before work starts
Line-by-line pricing in your proposal. No commitment required to receive an estimate. Budget ranges: from assessment-only to full enterprise migration.
How a $70M home furnishings brand replatformed without missing a beat
Half Price Drapes is a multi-channel home furnishings retailer selling window treatments, bedding, and decor across ecommerce and physical channels.
Their data sat fragmented across systems. They had no real-time inventory visibility. Their old platform could not handle the scale or the complexity of the business.
We unified inventory, orders, and customer data through a full migration and ERP integration. We replaced the legacy build with a conversion-focused, mobile-first theme across every channel. We added Klaviyo for lifecycle email automation to a large subscriber base. Real-time dashboards replaced manual reporting.
Annual revenue post-migration
Integrated analytics sharpened operations. Inventory accuracy and customer experience improved on every channel. A faster, optimized store and targeted email drove steady conversion growth.
What makes a migration succeed or fail
The migration itself is not the hard part. The planning, sequencing, and cutover discipline determine whether your rankings hold and your revenue continues on day one.
Migration questions answered
Real objections from ecommerce teams who have been through this. No platitudes.
They should not, as long as the migration ships a complete redirect map. We map every indexed URL to its BigCommerce equivalent. We deploy and validate 301 redirects on staging before your DNS changes.
Most stores complete in 45 days from project kickoff. Stores with complex integrations, large catalogs (over 50,000 SKUs), or custom B2B logic may require 60 to 75 days. Your go-live date is committed at the start of the project, not estimated. The audit in week one determines whether your store fits a 45-day or extended track before any build work begins.
Products and variants, images, pricing, inventory, all order history, customer accounts and addresses, product reviews, blog content, and gift card balances. Every data object is counted in the source platform and verified against the count in BigCommerce before cutover. A data integrity report is shared with you before the go-live date is confirmed.
Yes. Every integration is mapped in the audit phase and reconnected on staging during the build. Common integrations include NetSuite, Brightpearl, Cin7, ShipBob, ShipStation, Klaviyo, Yotpo, Stripe, Braintree, and Google Shopping. Integration quality assurance runs in parallel with theme and function development so that all connections are validated before the cutover date is locked.
Every cutover includes a documented rollback plan with a 15-minute decision window. If a critical issue is detected in the first 15 minutes post-DNS change, DNS is reverted and the previous platform comes back online within minutes. The cutover process is rehearsed in a full dry run on staging the week before go-live so every team member knows the exact steps. A live rollback has not been required on any project in the last two years.
Migration cost is scoped based on catalog size, integration count, and custom functionality requirements. Assessment-only projects start from $2,500. Standard migrations (under 5,000 SKUs, up to 4 integrations, theme migration) typically range from $8,500 to $18,500. Complex migrations with custom B2B workflows, large catalogs, or multiple integrations are priced after the audit. No commitment is required to receive a scoped estimate. See the full cost breakdown on the BigCommerce migration cost page.
