Migration playbook · from Square Payments

Migrating from Square Payments to multiflow — the 10-day playbook

Square is the cleanest on-ramp to payments in the industry — and also the cleanest trap. Your customer directory, card-on-file vault, invoice subscriptions, and terminal firmware are all tightly coupled to Square's ecosystem. In ten business days we extract the portable pieces, replace the Square-only pieces with open-standards equivalents, and migrate your portfolio to multiflow without losing a single recurring invoice or in-person tap.

Key takeaway

Flat-rate processors optimise for onboarding friction, not P&L. Every line above that reads "flat" on the left and "IC +" or "tiered" on the right is a line where multiflow returns margin that was previously opaque to you.


The 7-step migration
from kickoff to full cutover.

What this buys you

Seven days, one operator ceremony per day, zero weekend overtime. Each step is reversible through day 30 — you do not fly one-way until the Square Payments drain window closes.


Day-1 data export checklist
pull these before you sign anything.

Everything below is yours under Square Payments's ToS. Export now, before underwriting opens — it's faster while you're still a customer in good standing.

Why you pull first

Once you submit notice-of-migration, some processors throttle export API limits. You want these files in your S3 bucket before anyone at Square Payments knows you're leaving.


Gotchas operators hit
learn from their scars.

Operator-reported pitfalls

Square Gift Cards. Square gift cards are a closed-loop Square product. You cannot port outstanding gift card balances to another processor directly. Options: honor outstanding balances on Square for 12 months (leave Square account partially open), buy out the liability from customers, or issue multiflow gift cards as an exchange. We recommend option 1.

Square Payroll. Not a payments product but bundled. If you use Square Payroll, migrate to Gusto or Rippling in parallel. Don't try to use multiflow for payroll — we don't do that.

Terminal firmware. Square terminals are locked to Square — you cannot flash them to another processor. We provide loaner hardware (Clover Flex or PAX) at zero cost under a 12-month agreement. Return-to-Square hardware must be wiped and returned at your cost per Square's lease agreement.

Square Capital loans. If you have an outstanding Square Capital advance, it continues to draw from any residual Square processing volume. We can't migrate that — you either pay it off early or leave enough Square volume to service it.

Square Online website. If your website is built on Square Online (the hosted site builder), you'll need to rebuild on WooCommerce / Shopify / Webflow. Square Online isn't portable.


Rollback plan
if something goes sideways.

30-day reversibility window

Rollback through day 30 is straightforward: repoint online checkout back to Square, terminals stay as loaners (we recover on day 31+), unmigrated invoice subscriptions stayed on Square so they never stopped. Migrated subs are on multiflow — you'd cancel + recreate on Square.

The expensive part of rollback is terminal logistics. If you've activated more than 10 multiflow terminals and want to return to Square, you'll need to lease or buy Square hardware again at roughly $169-299 per terminal. This is rarely enough reason to reconsider — by day 15 you're usually seeing IC+ savings that justify staying.


Why operators leave Square

Square earns its pricing premium on simplicity. If you run a single location, flat-rate pricing is easier to understand than interchange-plus. The breakeven is roughly $200k-300k per location in annual card volume — under that, Square's 2.6% is competitive; over that, the math flips sharply. Multi-location operators, multi-brand operators, and anyone running over $1M annually are leaving 0.5-1.5 percentage points on the table by staying on Square's flat rate.

The second driver is risk tolerance. Square's hold-first-ask-questions-later posture works for low-risk retail but is catastrophic for operators in nutra, supplements, event tickets, high-ticket services, and anything Square flags in its opaque Risk review. Named underwriter access on multiflow means a human picks up the phone within hours, not days.

From the Square Payments migration field notes

What you lose and what you gain

You lose: the polished Square Dashboard, Square Marketing (email), Square Payroll, Square Capital (loans), Square Gift Cards (closed loop), and the 10-minute onboarding. You gain: interchange-plus pricing, per-brand descriptors, named underwriter, multi-acquirer routing, faster settlement at lower cost, and a dispute queue that doesn't silently eat your response window.


FAQ

Questions operators ask
before they sign.

01 What happens to my terminals?
Square terminals get returned or kept as backup; multiflow ships loaner terminals (Clover or PAX) at no cost.
02 Do customer Cards-on-File port?
Yes. Square releases the fingerprint + last4 and we re-authorize through a vault port on day 3.
03 What about my Square Marketing email list?
Export as CSV and migrate to your preferred ESP (Klaviyo, Brevo, Mailchimp). We recommend Klaviyo for e-commerce.
04 Can we keep Square Invoices?
No — multiflow has its own invoicing. Subscriptions migrate 1:1, one-time invoices generate through the new system.
05 How long do we keep the Square account open?
60 days in drain mode — longer than Stripe because Square's chargeback resolution runs 45-60 days.
06 Do we lose Square gift card balances?
Not immediately. Keep Square open for 12 months to honor outstanding balances, or buy out the liability from customers.
