How to Set Up Pre-Authorized Debit to Collect Recurring Fees Automatically

If you run a business with recurring fees, monthly retainers, or subscription-style billing, you already know the pain. You deliver the work, you send the invoice, and then you wait. You send a reminder. You wait again. You have a slightly awkward conversation. This happens every single month with the same clients.

Pre-authorized debit fixes this. Instead of asking clients to pay you, you pull the funds directly from their bank account on a schedule you both agreed to upfront. One setup, zero monthly friction.

What Pre-Authorized Debit Actually Is

Pre-authorized debit, or PAD, is a payment method where a business is authorized to withdraw funds from a client's bank account on a recurring or one-time basis. The client signs a PAD agreement upfront. After that, you initiate the transaction and the money moves automatically.

PAD is processed through the Payments Canada network, the same infrastructure that handles direct deposit and electronic fund transfers in Canada. It is not a credit card charge and it is not an e-transfer. Funds move bank-to-bank.

There are two types of PAD agreements. A personal PAD covers individual clients. A business PAD covers company accounts. The rules around notification and cancellation rights differ slightly between them, but the core mechanics are the same.

What Owners Get Wrong and Why It Costs Money

Most small business owners who still send monthly invoices are leaving time and money on the table. The obvious cost is administrative: someone spends hours every month sending invoices, following up, and reconciling payments. That is time not spent on client work or business development.

The less obvious cost is cash flow unpredictability. When clients pay on their own schedule, your receivables are lumpy. You might have a great collections week followed by two bad ones. That makes planning harder and can force you to hold more cash buffer than you actually need.

There is also a collections risk. The longer a receivable sits, the harder it is to collect. A client who is three months behind on a retainer is a very different conversation than a client who has pre-authorized payments and simply has not been in arrears.

The CFO Perspective

For any business billing the same client the same amount on a recurring basis, PAD should be the default. The question is not whether to do it. The question is which platform to use and how to phrase the agreement.

A consulting firm I worked with had eight retainer clients and was sending manual invoices to all of them. Collections averaged 22 days. After switching to PAD for six of those eight clients, collections dropped to effectively zero days. The money arrived on the first of the month without anyone lifting a finger. The cash flow impact was immediate and measurable.

PAD also signals professionalism. When you ask a client to sign a PAD agreement during onboarding, it frames the relationship as a structured engagement, not a favour-based arrangement where payment is optional until reminded.

How to Set It Up

You have two practical options for implementing PAD as a small business owner in Canada.

Option 1: Use a payment platform that handles PAD. Services like Rotessa, Plooto, and GoCardless let you send clients a digital PAD agreement, collect their banking information securely, and schedule recurring withdrawals. These platforms handle the Payments Canada compliance requirements and give you a dashboard to manage authorizations. Fees are typically per-transaction or a low monthly flat rate.

Option 2: Work through your bank or a payment processor. Many Canadian banks offer PAD processing for business accounts, often through their merchant services arm. Setup is more manual and the interface is less modern, but it works and may integrate with existing banking relationships.

What to Do About It

1. Identify your recurring billing clients. Pull a list of every client billed the same or similar amount monthly. These are your PAD candidates. Start there.
2. Choose a PAD platform. For most small businesses, a dedicated platform like Rotessa or Plooto is simpler than going through the bank. Compare per-transaction fees against your volume to pick the cheaper option.
3. Draft a compliant PAD agreement. Payments Canada requires specific language in PAD agreements. Most platforms generate this for you. If you are doing it manually, review the Payments Canada rules for mandatory PAD agreement content or have a lawyer review it.
4. Roll it into your client onboarding. The easiest time to get a PAD agreement signed is before work starts. Include it alongside your engagement letter or service agreement. Asking an existing client to switch mid-engagement requires more explanation, but the conversation is straightforward: you are moving to automatic billing to simplify administration for both sides.
5. Communicate clearly before the first withdrawal. Payments Canada rules require you to notify the client before the first debit and in advance of any changes to amount or date. Most platforms automate this. Make sure you know what notices are going out and when.
6. Keep your records. Store signed PAD agreements in your client files. If a client disputes a transaction, the signed agreement is your protection.

What PAD Cannot Do

PAD works best for fixed, predictable amounts. Variable billing where the amount changes every month requires either a separate authorization per transaction or a PAD agreement with a variable-amount clause. This is possible but adds friction.

PAD also has a reversal window. Clients can dispute a debit within 90 days for personal accounts and a shorter window for business accounts. This is rare for legitimate engagements, but it means PAD is not a substitute for a solid client relationship and a clear scope of work.
