Business Information** The initial section of the Merchant Signup Form collects key information about the merchant’s business, including their country, business type, industry classification, and registered business address. It also captures important processing details, such as the estimated annual processing volume and the average transaction value of individual transactions. \*Sample images for the US and Canada ![image (47)](https://support.apxium.com/hs-fs/hubfs/image%20(47).png?width=670&height=228&name=image%20(47).png) ![Merchant Application](https://support.apxium.com/hs-fs/hubfs/Merchant%20Application.jpg?width=670&height=783&name=Merchant%20Application.jpg)   **2. Ownership Information** The Owners section collects information about the authorized representatives, stakeholders, and owners associated with the merchant’s business. This includes details such as their email address, mailing address, phone number, and date of birth. The merchant is also required to create a username and password for the primary owner’s user account. This account will serve as the primary parent user login, providing access to the merchant entity within the Payrix Pro Portal. ![Merchant Application 1](https://support.apxium.com/hs-fs/hubfs/Merchant%20Application%201.jpg?width=670&height=736&name=Merchant%20Application%201.jpg) If the Partners have equal ownership, the Managing Partner may represent the firm. In this case, no further ownership details are needed. Note: We recommend using the common user email address (accounts@xxxx.com) in the Owner’s Information section. This email will be set as the Master Admin and will receive Payrix notifications, which helps avoid future changes.   **3. Bank Account Information** The Bank Account section requires merchants to provide their bank account details for transaction processing. This includes supplying the routing number, account number, and account type, either via secure Plaid integration or through manual entry. Using Plaid, merchants can securely access their online banking account to link it directly with Payrix Pro. This streamlined process minimises manual entry errors and provides real-time account validation, helping to prevent funding issues once payment processing begins. ![](https://support.apxium.com/hs-fs/hubfs/image-20250916-235018-png.png?width=670&height=338&name=image-20250916-235018-png.png)   **4. Legal Compliance Agreements** The final section of the Merchant Signup Form requires merchants to review and acknowledge the **terms, conditions, and disclosures**. This section also enables merchants to provide required signatures or submit supporting documents as needed. ![Screenshot 2026-09-07 091126](https://support.apxium.com/hs-fs/hubfs/Screenshot%202026-09-07%20091126.png?width=670&height=340&name=Screenshot%202026-09-07%20091126.png)   Keep an eye on your inbox — we will follow up if Payrix needs any additional documents or to share the good news once your application is approved!   - [Article Navigation Guide](https://support.apxium.com/knowledge/article-navigation-guide?hsLang=en#main-content) - [Article Navigation Guide](https://support.apxium.com/knowledge/article-navigation-guide?hsLang=en#article-navigation-guide) - [Apxium Collect](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#main-content) - [General Features](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#general-features) - [Communications](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#communications) - [Client Experience](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#client-experience) - [Payments, Settlements & Reconciliations](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#payments-settlements-reconciliations) - [Engagement / Proposals](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#engagement-proposals) - [APX Auto (Direct Debiting Invoices)](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#apx-auto-direct-debiting-invoices) - [Instalment Agreements (Non-SOR On Balance Sheet Instalments)](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#instalment-agreements-non-sor-on-balance-sheet-instalments) - [Professional Fee Funding (SOR) - Funded Instalments](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#professional-fee-funding-sor-funded-instalments) - [Reports](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#reports) - [Integrations](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#integrations) - [Onboarding Articles & Other Helpful Guides](https://support.apxium.com/knowledge/apxium-collect?hsLang=en#onboarding-articles-other-helpful-guides) - [Apxium Audit Safe](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#main-content) - [General Features](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#general-features) - [Creating Offers/Subscriptions](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#creating-offers-subscriptions) - [Offer Emails and Documentation](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#offer-emails-and-documentation) - [Accepting / Declining Audit Safe Subscription](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#accepting-declining-audit-safe-subscription) - [Active Audit Safe Subscriptions](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#active-audit-safe-subscriptions) - [Audit Safe Renewal / Rollover](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#audit-safe-renewal-rollover) - [Pricing](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#pricing) - [Others](https://support.apxium.com/knowledge/apxium-audit-safe?hsLang=en#others) - [Apxium Pay My Bill](https://support.apxium.com/knowledge/apxium-pay-my-bill?hsLang=en#main-content) - [Pay My Bill](https://support.apxium.com/knowledge/apxium-pay-my-bill?hsLang=en#pay-my-bill) - [Payments and Settlements](https://support.apxium.com/knowledge/apxium-pay-my-bill?hsLang=en#payments-and-settlements) - [Communications](https://support.apxium.com/knowledge/apxium-pay-my-bill?hsLang=en#communications) - [APX Auto (Direct Debiting Invoices)](https://support.apxium.com/knowledge/apxium-pay-my-bill?hsLang=en#apx-auto-direct-debiting-invoices) - [Payrix](https://support.apxium.com/knowledge/apxium-pay-my-bill?hsLang=en#payrix) - [Client POS - Non Integrated \[North America\]](https://support.apxium.com/knowledge/client-pos-non-integrated-north-america?hsLang=en#main-content) - [Client POS - General Features](https://support.apxium.com/knowledge/client-pos-non-integrated-north-america?hsLang=en#client-pos-general-features) - [APX Capital - Tax Pay for Introducers](https://support.apxium.com/knowledge/apx-capital-tax-pay-for-introducers?hsLang=en) - [APX Capital - Tax Pay For Borrowers](https://support.apxium.com/knowledge/apx-capital-tax-pay-for-borrowers?hsLang=en) [![Apxium Advanced Software Solutions for Accountant](https://support.apxium.com/hs-fs/hubfs/Logos/apxium-logo.png?width=144&height=50&name=apxium-logo.png "Apxium Advanced Software Solutions for Accountant")](http://www.apxium.com?hsLang=en) Copyright © 2025, Apxium HQ
