Everything you need to succeed with Finix.

Omnichannel payment processing enables merchants to accept payments online, in store, and on mobile through one connected system, with one processor, one reporting view, and one payout. It’s relevant whether you run a storefront and a website, a restaurant taking dine-in and delivery orders, or pop-up markets alongside a fixed location. The everyday problem it solves is where two payment setups don’t align on what was sold, what was refunded, and what you were paid. Finix is an omnichannel payments platform that brings online and in-person transactions into one dashboard, making it easier to manage payments across the different ways you sell.

Ecommerce payment methods are the ways a shopper can pay at checkout. Every online store owner needs to decide which ones to offer. Cards are the most common starting point, but today’s shoppers also opt for digital wallets, bank transfers, buy now, pay later (BNPL), and QR payments. Each can have different processing costs, settlement times, and dispute considerations. The right mix depends on what you sell and who buys it. Finix is a payments processor that lets growing businesses accept cards, ACH, Apple Pay, and Google Pay from one platform, online and in person.

Accounting firms can collect client payments through a billing tool bundled into their practice management software, through a profession-specific payment solution, or through a direct processor like Finix. Each option handles in-office payments differently and comes with its own pricing model. This guide compares five payment processors for accounting firms, explains what each one is built for, and shows how different pricing models can affect the cost of processing a $3,000 retainer invoice.

An accounting firm payment system brings together the tools you use to bill clients, accept payments, and record those payments in your books. While many search results focus on individual products, this guide explains how the whole system fits together. It’s for accounting firms setting up client payments for the first time or rebuilding an existing setup, including where a processor like Finix fits.

Invoicing and payment processing often come bundled as one solution, but they do two different jobs. Invoicing creates and sends the request for payment. Payment processing verifies the card or bank account and moves the money once your client pays. Understanding how the two work together helps you compare solutions and decide what you need if you want to build billing into your own software. Finix is a direct payment processor that handles card and bank payments, invoicing, and merchant onboarding for growing businesses in the US and Canada.

Payment processing for professional services means accepting client payments by card and bank transfer, and knowing what each one costs you to collect. If you run or manage the finances at a consulting, accounting, legal, or agency firm, your invoices are likely large and infrequent, which changes the math on every pricing model. Finix is a direct processor with interchange-plus pricing, online and in-person payments, and support you can reach by phone when you need it.
