Chasing down monthly retainer payments from 50+ clients isn't why you became an accountant. Yet here you are, spending hours every month following up on the same recurring invoices, dealing with "I forgot" emails, and reconciling payments that trickle in whenever clients remember to log into their bank portal. 

There's a better way. Auto payments aren't just convenient; they're transformative for accounting firms. Here's your complete guide to setting up auto payments that actually work, without the technical headaches or client pushback. 

Why accounting firms need auto payments more than anyone

Accounting firms run on predictable, recurring revenue. Monthly bookkeeping, quarterly advisory calls, and annual tax prep; these services happen on a schedule. So why are you still manually invoicing each cycle? 

Recurring payments offer predictable revenue and cash flow, with businesses experiencing fewer missed payments and lower delinquency rates because customers are automatically charged. For firms billing 20, 50, or 100+ clients monthly, that predictability is everything.  

The numbers back this up. In 2024 alone, businesses processed 7.3 billion B2B payments through the ACH network, an 11.6% jump from 2023, according to Nacha. The shift toward automated recurring billing isn't just a trend; it's becoming standard practice.  

But here's what most accounting firms miss: the real cost isn't just late payments. It's the hours your team spends on payment admin instead of billable client work. Every invoice you manually create, every follow-up email you send, every payment you reconcile; that's revenue-generating time lost to busywork. 

Understanding your auto payment options

Not all recurring payment systems are created equal. Here's what you need to know about your primary options. 

ACH payments: The accounting firm's favourite

ACH payments are electronic transfers that move money directly between bank accounts through the Automated Clearing House network, providing a secure and low-cost way for accounting firms to collect client payments. For recurring billing, ACH is typically your best bet.  

Why? Lower fees (usually $0.25–$0.75 per transaction versus 2.5–3.5% for credit cards), reliable processing, and same-day ACH volume increased 45% in 2024, making it faster than ever.  

ACH works particularly well for retainer arrangements, monthly bookkeeping fees, and subscription-based advisory services where the amount stays consistent. 

Credit card auto-pay: When it makes sense

Credit cards cost more but offer advantages for certain clients. Some businesses prefer paying by card to earn rewards points or maintain short-term cash-flow flexibility. If your firm serves startups or high-growth companies, offering card payments as an option keeps you competitive. 

The key is letting clients choose. Giving clients multiple payment options makes it easier for them to pay for your services, and the higher their chances of completing payments immediately. 

What accounting firms actually need

Here's the thing: most payment processors weren't built for professional services. They're designed for e-commerce or SaaS companies, which means you're constantly working around limitations. 

Accounting firms need: 

• Native accounting software integration so payments sync automatically to QuickBooks Online, Xero, or whatever you use 

• Faster payment options like instant real-time payments

• Client-specific payment tracking that ties to engagement letters and service agreements 

• Flexible billing schedules that handle monthly retainers, quarterly services, and one-off projects from the same platform 

• Automated reconciliation that matches payments to invoices without manual intervention

This is where platforms built specifically for professional services, like Forwardly, make the difference. Instead of cobbling together a payment processor, accounting software, and manual reconciliation, everything runs through one system designed for how accounting firms actually bill. 

Step-by-step: Setting up recurring payments

Here's how to implement auto payments without disrupting your current workflow. 

Step 1: Choose the right payment platform

Skip the generic payment processors. You need a platform built for professional services that understands the accounting workflow. 

When evaluating platforms, prioritize accounting software integration for direct sync that eliminates manual data entry, client payment portals that allow clients to authorize payments without friction, automated reconciliation so payments match to invoices automatically.  

Forwardly checks all these boxes and goes further: AI-powered bill capture means your invoices get created and sent automatically based on your engagement terms. When a client's monthly bookkeeping service comes due, Forwardly generates the invoice, charges the saved payment method, and reconciles everything in your accounting software, without you lifting a finger. 

Step 2: Get client authorization right

NACHA regulations require explicit client authorization before you can pull funds from their bank account. This protects both you and your clients.  

Your authorization form must include: 

• Client's name and address 

• Bank name, routing number, and account number 

• Payment amount and frequency (monthly, quarterly, etc.) 

• Start date for recurring charges 

• Clear cancellation terms 

• Client signature and date

The good news? Modern platforms handle this digitally. With Forwardly, clients receive a secure authorization form via email, sign it electronically, and their payment information is stored with bank-level encryption. No printing, scanning, or filing paper forms. 

Step 3: Frame it as client convenience, not firm benefit

The conversation matters. Don't pitch auto payments as "easier for us." Position it as a convenience upgrade for them. 

Try this: "To save you the monthly task of logging in and manually processing payment, we offer automatic billing through our secure payment platform. Your retainer is charged on the same day each month. You'll receive an invoice beforehand, and you get a receipt automatically. You can update or cancel anytime." 

Most clients appreciate not having another task on their plate. The ones who prefer manual payment will tell you; for everyone else, it's one less thing to remember. 

Step 4: Start with new clients

Roll out auto payments to new clients first. Make it part of your standard engagement process. New clients have no existing workflow to change, so there's no friction. 

For existing clients, introduce it during contract renewal: "As we renew your engagement, I wanted to mention we've upgraded to automated billing. It'll save you the hassle of manual payments each month, I can get you set up in about two minutes if you're interested." 

With Forwardly's client portal, the setup literally takes minutes. Clients enter their payment information once, you set their billing schedule, and everything runs automatically from there. 

Step 5: Let automation handle the heavy lifting

Once you have authorization, your payment platform should handle everything else: 

• Automatic invoice generation based on your engagement schedule 

• Pre-payment notifications so clients aren't surprised 

• Payment processing on the scheduled date 

• Instant reconciliation in your accounting software 

• Receipt delivery to the client 

• Failed payment handling with automatic retry logic

Overcoming client objections

You'll hear pushback. Here's how to address the common concerns. 

"I like to review invoices before paying" 

"You'll still receive your invoice five days before payment. If anything looks off, just let me know, and we'll hold the payment." 

This addresses the concern while maintaining automation for 99% of transactions. Forwardly's notification system ensures clients always see charges before they happen. 

"What if I need to cancel?" 

"You control this completely. You can update or cancel recurring billing anytime through your client portal, or just send me a message. There's no penalty, no hassle." 

Clear exit terms remove the biggest psychological barrier to auto-pay. And with Forwardly, clients can manage their own payment settings, which reduces your admin burden. 

"I don't want to give you my bank details" 

"Totally understand. We process payments through Forwardly, which uses bank-level encryption and is NACHA compliant. Your payment information never touches our systems, it's stored securely by the payment processor, the same way your online banking works. You can also use a credit card if you prefer." 

Security concerns are legitimate. Don't minimize them. Show clients that you're using enterprise-grade payment infrastructure. 

The less obvious benefits (that actually matter more)

Beyond predictable cash flow, auto payments deliver advantages you might not have considered. 

Reduced administrative overhead

The recurring billing feature sends invoices to clients at a set date every week or month, saving you the time and error of creating the invoice from scratch each time. What used to take 10 minutes per client now takes zero.  

Scale that across 50 clients and 12 months. That's 100 hours back in your year, hours you can spend on advisory services, business development, or literally anything more valuable than invoice admin. 

With Forwardly's automated workflows, you're not just eliminating invoice creation; you're removing the entire payment cycle from your to-do list. Bills get captured, invoices get sent, payments get processed, and everything reconciles automatically. 

Fewer accounting errors

Manual data entry creates mistakes. Payment amounts get transposed, invoices get sent to wrong emails, reconciliation becomes a puzzle. Automation eliminates most of these errors because the system handles the same process identically every time. 

Forwardly's automatic reconciliation means payments sync to the correct client and invoice in your accounting software without human intervention. No more month-end reconciliation marathons trying to figure out which payment belongs to which invoice. 

Improved client retention

This one's counterintuitive, but clients on auto-pay stick around longer. Why? Because canceling requires active effort. They have to remember to cancel, find the cancellation process, and follow through. 

That's not manipulation; it's removing unnecessary friction. Clients who derive value from your services stay because leaving is slightly less convenient than staying. When renewal is automatic, retention improves naturally. 

Better cash flow visibility

When you know exactly when every client payment will hit your account, financial planning becomes simple. You can forecast payroll, plan investments, and make business decisions with confidence instead of hoping enough clients pay on time this month. 

Forwardly's dashboard shows you projected cash flow based on scheduled payments, so you always know what's coming and when. 

How Forwardly makes this easier (and why it matters)
