Multi-tenant Payments App Agent
Bookkeeper logs into Butterfield Bank portal, enters vendor name and bank details, enters amount, submits. Waits for email 2FA code. Approver logs into a different Butterfield account, reviews the payment, approves, retrieves a second 2FA email. Process repeats for every vendor. No audit trail. Bank details can be changed by anyone with portal access. Vendor emails can be intercepted and payments redirected.
Submitter selects vendors from the secure vendor database, enters amounts, sees them grouped by currency, submits the batch. Approver reviews the batch in Multi-tenant Payments App Agent, authorizes with 2FA, and the EDI file is generated. Submitter downloads the file and uploads it to Butterfield once. Every action is logged: who selected vendors, who approved, when the file was generated, when it was uploaded. Bank-detail changes require Approver authorization before they take effect.
Manual bank logins create fraud risk and operational bottlenecks
Cayman accounting firms and law firms pay vendors by logging into Butterfield Bank portals one payment at a time.
Encompass has a dedicated person logging into 12 Butterfield accounts every day to pay vendors one by one.
Attackers intercept vendor payment notifications and redirect the payment to attacker-controlled accounts. The current manual process has no controls to prevent this.
One person with portal access can change vendor bank details and release payments without a second person's knowledge or approval.
Batch payments with dual approval and audit trails
Select all vendors for the day, group by currency automatically, submit once. The EDI file is ready for bank upload without re-entering payment details.
Submitter selects vendors and amounts. Approver reviews and authorizes with 2FA. Neither role can release payments alone.
Changing a vendor's bank account number requires Approver sign-off. The change goes into a pending state until approved, preventing the intercepted-email fraud vector.
Every action is recorded: vendor add, bank-detail change request, approval, EDI generation, upload confirmation. The log cannot be deleted or edited, so fraud forensics are possible.
Multi-tenant Payments App Agent replaces manual portal logins with a single workflow: select vendors, batch by currency, authorize with 2FA, download the Butterfield-format EDI file. Bank-detail changes go into a pending state that requires Approver authorization before they take effect, so a bookkeeper cannot redirect payments by changing vendor account numbers. Every action is logged: who selected which vendors, who approved the batch, when the EDI file was generated, when it was uploaded to the bank. The audit trail is immutable and queryable, so fraud forensics are possible.
From vendor selection to bank-uploadable EDI file
Multi-tenant Payments App Agent turns a multi-step manual process into a single workflow. Submitter picks vendors and amounts, the system groups by currency, Approver authorizes with 2FA, and the EDI file is ready for download.
Pick vendors from the secure vendor database, enter the amount to pay each one. The system auto-groups payments into a KYD batch and a USD batch.
See the total per currency, vendor count, and line-by-line list. Edit amounts or vendor selection before you submit. Once submitted, the batch is locked.
Approver sees the pending batch in their queue, reviews it, and authorizes with a TOTP code from Authy or Google Authenticator. The batch transitions to approved.
Multi-tenant Payments App Agent generates a Butterfield Bank-compatible EDI file for each currency. The file contains payee bank details, amounts, references, and dates in Butterfield's exact format.
Download the EDI file from Multi-tenant Payments App Agent and upload it to the Butterfield Bank portal by hand. Confirm the upload in Multi-tenant Payments App Agent so the audit log captures the full handoff.

Pricing and build model
Multi-tenant Payments App Agent is a custom build for Carl Brenton (Encompass Cayman) and James (Cayman-based accountant and law firm operator). The build is scoped as a dedicated senior AI engineer placement on a weekly sprint cadence, with a cost ceiling of sub-six-figures. Milestone 1 (M1) delivers a working prototype for internal use by Encompass and James. Milestone 2 (M2) onboards a friendly external customer (likely one of James's law firm clients). Milestone 3 (M3) opens self-serve onboarding for any Cayman business.
- Scoped build with dedicated senior engineer on weekly sprint cadence.
- M1 = internal use by Encompass and James. M2 = friendly external customer. M3 = open onboarding.
- Cost ceiling is sub-six-figures. Scope discipline prioritized over feature expansion.
- Usage-based pricing model for external customers is deferred to M2 and M3 planning.
Do I need to use Butterfield Bank to use Multi-tenant Payments App Agent?
Yes. Multi-tenant Payments App Agent generates EDI files in Butterfield Bank's format. Other Cayman banks (CIBC, RBC, Cayman National, Scotiabank) use different EDI formats. Multi-bank support is planned for a future phase.
Can Multi-tenant Payments App Agent automatically upload EDI files to Butterfield, or do I have to upload manually?
In version 1, you download the EDI file from Multi-tenant Payments App Agent and upload it to the Butterfield portal by hand. Automated upload via browser automation is planned for version 2.
How does Multi-tenant Payments App Agent prevent fraud when changing vendor bank details?
When someone requests a change to a vendor's bank account number, the change goes into a pending state that requires Approver authorization before it takes effect. This prevents the intercepted-email fraud vector where attackers redirect payments to attacker-controlled accounts.
What happens if I reject a payment batch as an Approver?
Rejected batches return to the Submitter with comments explaining why the batch was not approved. The Submitter can then edit the batch and resubmit it for approval.
Can I pull vendor payment data directly from QuickBooks Online into Multi-tenant Payments App Agent?
Not in version 1. Multi-tenant Payments App Agent requires manual entry of payment amounts. QuickBooks Online integration to pull bills and invoices is planned for version 2.
Is Multi-tenant Payments App Agent suitable for payroll payments?
No. Multi-tenant Payments App Agent is designed for vendor payments. Payroll has different approval workflows, tax withholding, and regulatory requirements that are outside Multi-tenant Payments App Agent's scope.
How many people need to approve a payment batch before it can be released?
Dual approval is the default: a Submitter selects vendors and amounts, and an Approver reviews and authorizes with 2FA. The configuration is per tenant, so some organizations may start with a single approver and add a second later.
Can I see a complete audit trail of all payment actions in Multi-tenant Payments App Agent?
Yes. Every action is recorded in an immutable audit log: who selected vendors, who approved the batch, when the EDI file was generated, when it was uploaded to the bank, and any changes to vendor bank details. The log cannot be deleted or edited, so fraud forensics are possible.
