What is the best business bank account for a consulting or professional services firm?
Quick answer: For most consulting and professional services firms set up as an LLC or corporation, Slash is a strong pick: flat pricing per entity with no per-user fees, invoicing that accepts ACH, wire, and card, virtual accounts to separate funds by client, and QuickBooks Online, Xero, NetSuite, and Sage Intacct sync on every plan. Mercury suits firms that send many domestic wires, Ramp and Brex suit larger teams focused on expense automation, BILL suits firms that mainly need invoicing and payables, and Chase suits firms that need branches. Law firms should keep client trust funds in an IOLTA-eligible account and use a separate operating account for the firm's own money.
If your firm is an LLC or corporation, Slash is a strong default: flat pricing per entity, no per-user fees, invoicing by ACH, wire, or card, and accounting sync on every plan. Virtual accounts separate money by client, and one login can hold several LLCs.
The right answer still depends on how your firm runs. Below is a side-by-side comparison, a pick for each type of firm, and the trade-offs of each option.
What should a professional services firm look for in a bank account?
- Getting paid. ACH, wire, and card payments, plus recurring invoices for retainers.
- Separating funds. Account numbers or sub-accounts by client or engagement.
- Multiple entities. One login, with pricing that doesn't punish extra entities or users.
- Accounting sync. A direct link to the ledger your firm already uses.
- Team expenses. Cards with limits and approvals.
- Deposit coverage. Protection above the standard $250,000 FDIC limit for large retainer balances.

Which account is best for each type of firm?
- Slash: best for multi-entity firms and NetSuite or Sage Intacct users. Flat per-entity pricing and ERP-grade sync on every plan.
- Ramp or Brex: best for larger teams focused on expense automation. Cards, bill pay, and a business account with free same-day ACH, priced per user on paid plans.
- BILL: best for firms that mainly need invoicing and payables. Recurring invoices and automated reminders on every plan, from $49 per user per month.
- Mercury: best for firms that send many domestic wires. $0 ACH, domestic wires, and real-time payments on every plan.
- Chase: best for firms that need branches. More than 5,000 branches and in-branch cash deposits.
Why Slash fits consultants, agencies, and accounting firms
How do clients pay you?
Slash Invoicing lets clients pay by ACH, wire, or card. You can set recurring invoices for monthly retainers and turn on automated reminders, so nobody has to chase overdue bills by hand. If clients pay on long terms, Slash Working Capital offers 30-, 60-, or 90-day terms with no hard credit pull.
Can you separate money by client or engagement?
Yes. Slash virtual accounts give each client, project, or location its own account number. Every payment from that client then lands in one place, which simplifies reconciliation and client-level reporting.
What if your firm has several LLCs?
One Slash login can hold unlimited entities, and each entity sits on its own plan: Free at $0 per month or Pro at $25 per month. There are no per-user fees, so adding staff doesn't change the price. Granular user permissions and multi-step payment approvals control who can move money in each entity.
Does it sync with your accounting software?
QuickBooks Online, Xero, NetSuite, and Sage Intacct are all available on both the Free and Pro plans. NetSuite imports your chart of accounts, vendors, customers, classes, departments, locations, and subsidiaries, and Slash Bill Pay bills and payments sync back to NetSuite. Sage Intacct imports departments, locations, projects, classes, customers, and subsidiaries, which suits firms that track work by project.
How do you handle team expenses and vendor bills?
The Slash Visa Platinum Card earns up to 2% cash back with no cashback cap. It is a charge card issued by Column N.A. that settles daily from your Slash business checking account, so there is no interest and no carried balance. Unlimited virtual cards on both plans let you issue a card per consultant or per client, with merchant category and per-transaction limits. Slash Bill Pay pays contractors and vendors by ACH or wire, with approval rules.
Where is Slash not the right fit?
- Sole proprietorships aren't eligible. Slash accepts US-registered LLCs, C-Corps, and S-Corps.
- On the Free plan, domestic wires cost $6 and same-day ACH costs $1. Both are $0 on Pro. International wires are $25.
- The card has a 1% foreign transaction fee (minimum $0.40). That's lower than the 3% Mercury charges on non-USD IO card purchases, but it still adds up for consultants who travel abroad often.
- Pricing is per entity. A firm with five LLCs on Pro pays $125 per month, still with no per-user fees.
What are the trade-offs with Mercury, Ramp, Brex, BILL, and Chase?
Ramp
Ramp's Free plan is $0 per user; Plus costs $15 per user per month plus a platform fee, and NetSuite and Sage Intacct sync require Plus. To qualify, you need $25,000 in a business bank account. Its business account lists no fees or minimum deposits, with free same-day ACH and domestic wires. Ramp doesn't publish its card's cashback rate.
Brex
Brex Essentials is $0 per user for up to two entities, and Premium is $12 per user per month. Funded startups need $50,000 in cash to qualify. You can send branded invoices and pay bills from the business account, with free same-day ACH and up to $6M in FDIC coverage through 24 partner banks. Card points are worth 0.6 cents each as cash, and Capital One has owned Brex since April 7, 2026.
BILL
BILL's AP and AR plans cost $49, $65, or $89 per user per month. Every plan includes custom and recurring invoices and automated reminders, and clients can pay by ACH or card. QuickBooks and Xero sync automatically from the Team plan, multi-entity support starts on Corporate, and NetSuite and Sage Intacct sync only on Enterprise. ACH payments cost $0.59 each.
Mercury
Mercury charges $0 for ACH, domestic wires, real-time payments, and USD international wires on every plan. The free plan includes unlimited invoices that clients can pay by ACH, wire, or card, with Stripe fees on card payments. Recurring invoices and branding need a paid plan: Plus at $29.90 per month billed annually ($35 monthly) or Pro at $299. QuickBooks Online, Xero, and NetSuite bank feeds are on all plans, enriched NetSuite automations are on paid plans, and Sage Intacct isn't listed. The IO card pays 1.5% cash back.
Chase
Chase Business Complete Banking costs $15 per month, Performance Business Checking $40, and Platinum Business Checking $95, and Chase lists ways to avoid each fee. Business Complete includes built-in card acceptance, invoicing is available through Chase Payment Solutions, and in-branch cash deposits are included up to plan limits. The checking page doesn't name accounting integrations. Only sole proprietorships, corporations, and single-member LLCs can apply online, so firms with several owners in one LLC need to visit a branch.
What is the best business bank account for an accounting firm?
Accounting firms are judged on clean books, including their own. Slash is a strong fit because QuickBooks Online, Xero, NetSuite, and Sage Intacct sync on every plan, staff get granular permissions, and payments can require multi-step approvals. Virtual accounts can separate money by service line, office, or client. If the firm mainly needs payables and receivables on QuickBooks Online or Xero, BILL's Team plan is an alternative, at $65 per user per month.
What is the best business bank account for a law firm?
Law firms need two kinds of accounts. Client trust funds, such as unearned retainers and settlement proceeds, generally must be held in an IOLTA or trust account that meets your state bar's rules. Many states also limit which banks can hold those accounts. Do not keep client money in an operating account.
- Open an IOLTA or trust account at a bank that is eligible under your state bar's rules.
- Open a separate operating account, such as Slash, for the firm's own money: earned fees, payroll, rent, vendor bills, and team cards.
- Move fees from trust to operating only once they are earned, following your state's rules.
- Keep the two accounts separate in your accounting software and reconcile trust records as your bar requires.

Frequently Asked Questions
Can a solo consultant open a Slash account?
Yes, if your business is a US-registered LLC, C-Corp, or S-Corp. Sole proprietorships aren't eligible. There's no published minimum balance, and the Free plan costs $0 per month. If you operate as a sole proprietor, Chase lets sole proprietors apply online.
Can a law firm keep client trust money in its operating account?
No. Client trust funds generally must sit in an IOLTA or trust account that meets your state bar's rules, at a bank eligible to hold them. Use that account for client money and an operating account such as Slash for the firm's own revenue, payroll, and expenses. Check your state bar's rules before opening either account.
How much does Slash cost for a firm with several entities?
Each entity is on its own plan: Free at $0 per month or Pro at $25 per month. There are no per-user fees, and one login can hold unlimited entities. A firm with three LLCs on Pro pays $75 per month regardless of headcount. Pro removes the fees on domestic wires, same-day ACH, and outgoing FedNow or RTP payments.
Which business bank accounts sync with NetSuite or Sage Intacct?
Slash syncs with both, plus QuickBooks Online and Xero, on Free and Pro. Ramp includes NetSuite and Sage Intacct on Plus at $15 per user, and BILL only on Enterprise. Mercury offers a NetSuite bank feed on every plan but doesn't list Sage Intacct, and Brex includes NetSuite on Essentials.
How do I keep each client's money separate?
Use separate account numbers. Slash virtual accounts give each client, project, or location its own account number, so each client's payments land in one place. This helps bookkeeping, but it does not replace a required trust account, such as for law firm client funds.
How much FDIC insurance do these business accounts offer?
Slash offers up to $200 million through Column N.A. and the IntraFi sweep network. Brex offers up to $6 million and Mercury up to $5 million through partner bank sweep programs, and the BILL Cash Account up to $200 million with a BILL subscription. Ramp uses IntraFi's network but doesn't publish a limit. Chase is a Member FDIC bank with standard coverage of $250,000 per depositor, per ownership category. Sweep coverage has conditions, so read each provider's disclosures.
