Flux lets it service providers take cards for convenience, ACH for larger invoices where the economics are friendlier, and pass the processing fee to the client at checkout where local rules allow.
Why it service providers choose Flux
ACH for large invoices
Route retainers and big invoices over ACH where the per-transaction economics beat cards.
Pass the fee where allowed
On consumer pass-through, the processing fee is added to the client's total at checkout, where local surcharging rules allow.
Books that reconcile
A QuickBooks sync keeps it service providers from retyping every payment into the accounting system at month end.
How it service providers get paid
For it service providers, ACH usually fits large invoices and retainers, cards suit smaller or on-the-spot payments, and Flux handles both through one integration with a clean record for your books.
A typical Flux setup for IT service providers
Managed services run on autopay. The monthly agreement, priced per seat or per device, is charged automatically to a stored card or debited by ACH on the first of the month, with ACH the better fit for larger contracts since it settles in 1-3 business days and does not expire the way cards do. Project work, migrations, and onboarding fees are invoiced separately with payment links, and out-of-scope hours are billed as they land.
Hardware resale is its own flow: larger one-time card or ACH charges for equipment, collected before you place the distributor order so you are never financing a client's server purchase. Where local rules allow surcharging, some providers apply the consumer pass-through option on hardware, since margins there are thin and tickets are large. The REST API connects billing to your PSA so seat counts and true-ups flow into the monthly charge automatically.
What IT service providers should watch
The recurring base lives or dies on payment method hygiene. Cards on file expire, get reissued after fraud, and quietly break autopay; ACH mandates are more durable for contract billing. Watch failed payments the day they happen, because a client three months behind on a managed contract is a collections problem you created by not noticing. True-ups deserve a line item and an email before the charge runs, never a surprise on the statement.
Hardware brings the chargeback exposure that services mostly lack: a large card-not-present charge for equipment is exactly what issuing banks scrutinize. Collect hardware payments against a signed quote, ship with tracking, and keep serial numbers on the invoice. At offboarding, bill the final month and any early-termination amount per the agreement promptly, while goodwill still exists; the last invoice to a departing client ages worse than any other receivable you carry.

What happens when a client's autopay card fails?
Failed charges show in your dashboard so you can retry or fall back to an ACH debit if one is authorized. Most providers move contract billing to ACH precisely because mandates do not expire or get reissued the way cards do.
Can our PSA drive the monthly billing amounts?
Yes. The REST API lets your PSA set each month's charge from current seat and device counts, so true-ups happen in billing automatically instead of in a painful quarterly cleanup.
How do we protect ourselves on large hardware orders?
Collect payment before ordering from the distributor, against a signed quote listing the equipment. Ship with tracking and keep serial numbers on the invoice, which is the evidence that resolves a hardware dispute in your favor.
