### [Cal2Cash](https://www.g2.com/products/cal2cash/reviews)

Cal2Cash is the billing layer Google Calendar never had. Independent professionals - coaches, trainers, tutors, therapists, consultants - already run their entire client schedule through Google Calendar. Cal2Cash plugs directly into that workflow: sign in once with Google, open any event, set your rate, and a shareable payment link appears inside the event. No second app. No invoicing software. No copy-paste of payment details into emails. Payment links are smart. Set a flat fee for a workshop or an hourly rate for a session - Cal2Cash calculates the amount from the event duration. Change the event length later and the amount updates automatically. You can cap the number of seats for group events, set an expiry date so a link closes at the right time, and offer early-bird discounts with a countdown that your clients see on their payment page. When the discount window closes, the price goes back to full without any action from you. The enforcement side is fully automated too. Set a due date, and if a client hasn't paid by then, a late fee is added automatically, they get an email notification, and the payment link reflects the new amount. Reminders go out on your behalf. Payment confirmations update your calendar event in real time. You always know who's paid, who's overdue, and what's coming in - from a single dashboard. Cal2Cash runs on a 14-day free trial with no credit card required. After the trial, the Pro plan is $19/month or $150/year (equivalent to $12.50/month). Payments are processed securely through Stripe. Cal2Cash never stores card details. The app is operated by RCLOUD LABS LLC and available at cal2.cash.

Payment processing software helps businesses securely handle and track business-to-business (B2B) payments from customers and to suppliers. It supports any organization that accepts non-cash payments by ensuring transactions are timely, accurate, and integrated with downstream financial systems.

### Core Capabilities of Payment Processing Software

To qualify for inclusion in the Payment Processing category, a product must:

- Collect customer payment information and relay it to a bank for approval or denial
- Transmit approval or denial of a transaction back to the customer or merchant
- Support multiple payment methods such as credit card, ACH, or wire transfer
- Define and track customizable payment rules, terms, and deadlines
- Identify errors such as late payments, overpayments, or failed transactions
- Integrate with ERP, accounting, or accounts receivable and accounts payable systems

### How Payment Processing Software Differs from Other Tools
