Switching Processors in the US

Each processor's own agreement sets the rules for leaving. Stripe's US agreement lets a business end it "at any time" by closing its account. Square says a business can deactivate "at any time". Helcim's US terms say a business can end its account at any time by calling support. Money can stay held after you leave: Helcim may keep a reserve for at least six months.

The short answer

When a business leaves a card processor, the processor’s own agreement decides what happens. This page sets out what three US agreements say: Stripe, Square and Helcim.

Four things matter when leaving:

  1. How to end it, and whether notice is needed.
  2. Fees for leaving, if any.
  3. Money still in the account.
  4. Money held back after you go, called a reserve: funds a processor keeps to cover refunds and chargebacks.

A chargeback is a sale reversed after the customer disputes it with their bank.

How each one ends

Provider (US)How to end it, per its terms
Stripe“User may terminate this Agreement at any time by closing its Stripe Account via the Stripe Dashboard.”
Square“You can also choose to deactivate your account at any time.” Square’s help page says this is done from Square Dashboard.
Helcim“You may terminate your Account at any time by calling Helcim’s Support team during Business Hours and following the instructions provided.”

Each provider can also end the relationship. Stripe “may terminate this Agreement or close User’s Stripe Account at any time.” Square says it “can terminate or deny you access to our services at any time, for any reason.” Helcim “reserves the right to terminate your Account for any reason, without notice, at any time.”

Fees for leaving

None of the pages we read from these three providers lists an early termination fee.

  • Square’s US pricing page says: “No hidden fees or locked-in contracts. Cancel or switch anytime.” Its help page says there is “no cost to keep your account open if you’re a seasonal business, using our subscription products, or switching to a new processor.”
  • Square also says subscriptions linked to the account must be cancelled separately.
  • Helcim’s US terms say that on termination, “you will not be entitled to any refunds of any fees, pro rata or otherwise”.

Other processors can charge to leave. That is set in each contract, and this page does not cover them. For how these fees work in Canada, see Early Termination Fees. Equipment leases from other companies are also not covered here; see Equipment Leases for the Canadian sources.

Money still in the account

Stripe. “Stripe accounts cannot be closed with an existing balance.” Stripe says “positive balances must first be paid out to the bank account on file” and “negative balances must first be brought to zero”. Scheduled payouts “will still occur”.

Square. “Closure of your Square Account will cancel any pending transactions. Any funds that we are holding in custody for you at the time of closure, less any applicable Fees, will be paid out according to your payout schedule”. Square also says that once deactivated, an account cannot be reactivated, and that payment history is no longer available. It suggests exporting payment history, the Item Library and the Customer Directory first.

Helcim. On termination, the business agrees to “complete all pending Transactions”, “stop accepting new Transactions” and “remove all Helcim or payment network logos from your website”.

Money held back after you leave

Provider (US)Holds and reserves after leaving, per its terms
StripeDefines a reserve as “collateral funds which Stripe holds and controls to satisfy any liabilities or potential liabilities”. Its support page says closing “doesn’t release the owner from any liability related to the account balance.”
Square“If an investigation is pending at the time you close your Square Account, we may hold your funds”. If you are later found entitled to them, “we will release those funds to you.”
HelcimMay require “an additional reserve” after termination, kept “for a minimum of six (6) months from the termination date” or until Helcim decides release is prudent. The balance left after that “will be paid to you.”

Refunds and chargebacks after you leave

Stripe says: “Once you close your Stripe account, you’ll no longer be able to process any refunds”. It suggests keeping the account open until refunds and disputes are resolved.

Square’s payment terms say termination “does not relieve you of obligations to pay Fees or costs accrued prior to the termination, Chargebacks, and any other amounts owed”. The terms list the chargeback and reserve sections among those that “survive termination”.

When the processor ends it

Helcim’s US terms list reasons it may end an account, including “Chargebacks in excess of Association monitoring guidelines”, “Non-payment of any amounts owing to us”, and appearing “on the Association Terminated Merchant File; or any other merchant watch list”.

Square’s terms say it will “take reasonable steps to notify you of termination” by email or at the next sign-in. Stripe says it “will notify User in accordance with Law.”

What this page does not cover

  • Contracts from processors other than these three, including any early termination fees.
  • Third-party equipment leases.
  • State laws on contracts.

Common questions

Is there a fee to leave Stripe, Square or Helcim in the US?

The pages we read from these three list no early termination fee. Square's US pricing page says there are no "locked-in contracts". Helcim's US terms say fees already paid are not refunded "pro rata or otherwise". Other processors' contracts can differ, and are not covered here.

What happens to money still in the account?

Stripe says positive balances must be paid out, and negative balances brought to zero, before an account can close. Square says funds it holds at closure, less fees, are paid out on the normal schedule, unless an investigation is pending. Helcim says amounts owed are paid under its reserve and transaction terms.

Can a processor hold money after I leave?

Yes, under these terms. Helcim may require a reserve for at least six months from the termination date. Square says it may hold funds if an investigation is pending at closure. Stripe defines a reserve as "collateral funds which Stripe holds and controls".

What about refunds and chargebacks after I leave?

Stripe says that once an account is closed, "you'll no longer be able to process any refunds". Square's payment terms say its chargeback sections survive termination. Helcim's terms say a business must complete all pending transactions when it ends its account.

How much notice do I have to give?

None is stated in the sections we read. Stripe's account can be closed from the Dashboard, Square's from Square Dashboard, and Helcim's by calling its support team during business hours.
