Flux lets management consultants 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 management consultants 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 management consultants from retyping every payment into the accounting system at month end.
How management consultants get paid
For management consultants, 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 management consultants
Consulting revenue arrives in large, irregular pieces: a project deposit at signing, milestone invoices as phases close, and a final payment at delivery. ACH is the workhorse for these five- and six-figure invoices, settling in 1-3 business days, with card as the fallback when a client's AP process prefers it. Retained advisory work runs as a monthly recurring charge. Each invoice carries a hosted payment link so the client's finance team can pay without a phone call.
Cross-border engagements are where stablecoins earn their place. An overseas client can pay a milestone invoice in stablecoins over Solana or Ripple (XRP Ledger), and the funds reach your merchant wallet instantly rather than moving through correspondent banking. For domestic work, QuickBooks sync keeps project revenue tied to the right engagement, and the REST API lets firms trigger invoices from their own project tracking the moment a milestone is marked complete.
What management consultants should watch
Your real risk is not chargebacks, it is payment terms. Enterprise clients default to net-45 or net-60, and a payment link does not change their AP calendar; a deposit collected at signing does. Structure engagements so the deposit covers early-phase work and each milestone invoice is due before the next phase begins. That converts collections from a negotiation at the end of the project into a gate during it, which is where your leverage actually exists.
Scope disputes surface at the final invoice. A signed statement of work with acceptance criteria per milestone is your protection, because it lets you invoice against agreed checkpoints instead of a single contested deliverable. On card payments for large invoices, expect the occasional bank-side review of an unusually large charge; a consistent billing descriptor and a complete invoice trail keep those reviews from hardening into disputes you have to fight.

What does Flux charge management consultants?
A flat 2.9% plus 30 cents per transaction, with volume discounts for higher-volume merchants and no setup fees or contracts. Accounts processing under $100,000 a year in card volume may be subject to a $20 monthly account fee. You can also pass the processing fee to the customer at checkout where local surcharging rules allow.
How fast do management consultants get their money?
Card payments settle in one to two business days and ACH in one to three business days. Stablecoin payments go to your wallet instantly.
Is there a practical limit on how large a single invoice payment can be?
Card networks and issuing banks apply their own per-transaction ceilings, so most firms take five-figure and larger invoices by ACH, which handles large transfers routinely and settles in 1-3 business days. Talk to us if your typical milestone runs unusually large.
What is the best way for an overseas client to pay us?
Stablecoins over Solana or Ripple (XRP Ledger) settle instantly to your merchant wallet, and your client pays in a currency-stable asset instead of initiating an international wire. Cards also work for foreign clients where their bank permits the charge.
Can we invoice automatically when a project milestone closes?
Yes. The REST API creates invoices and payment links programmatically, so your project tracking can trigger billing the moment a milestone is accepted. Payments then sync to QuickBooks against the right engagement.
