Big Red Cloud is an Irish small-business accounting platform, and its REST API exposes the full ledger model — customers, suppliers, sales and purchase invoices, cash payments and receipts, bank accounts, and nominal accounts — across 120 endpoints under /v1. The API supports list, single-item, and batch operations for most resources, plus dedicated endpoints for sending sales invoices, statements, and quotes by email. Authentication is by API key generated from the user's Big Red Cloud account, scoping access to that company's books. Suitable for syncing accounting data with e-commerce platforms, payment processors, or custom reporting tools.
Retrieve customer account transactions, opening balances, and outstanding quotes
Read nominal account ledger detail for a specific period or account ID range
Fetch company setup configuration including financial year and company logo
Patterns agents use Big Red Cloud API API for, with concrete tasks.
★ E-Commerce to Accounting Sync
Irish online retailers running on Shopify or WooCommerce push completed orders into Big Red Cloud as sales invoices, then mark them paid via cash receipts as the payment processor settles. POST /v1/customers handles new buyers, POST /v1/salesInvoices posts the order, and POST /v1/cashReceipts closes the loop. Batch endpoints make end-of-day catch-up runs efficient when the sync has been offline for a window.
Call POST /v1/customers for the buyer, POST /v1/salesInvoices with the line items, then POST /v1/cashReceipts when payment settles
Customer Statement Automation
Finance teams chase aged debt by sending statements at scheduled intervals. Big Red Cloud exposes /v1/email/sendEmailStatement to dispatch the customer's outstanding statement directly from the platform, with /v1/customers/{itemId}/accountTrans giving the reviewer the underlying transactions before they trigger the send. This removes the manual export-to-PDF-to-email loop most small finance teams still run.
Call GET /v1/customers/{itemId}/accountTrans, then POST /v1/email/sendEmailStatement with the customer ID to dispatch the statement
Quote-to-Invoice Workflow
Service businesses send quotes, win the work, and convert the quote to a sales invoice without rekeying. Big Red Cloud's API supports listing quotes for a customer through /v1/customers/{itemId}/quotes, emailing a quote with /v1/email/sendQuote, then creating the resulting sales invoice via /v1/salesInvoices and emailing it with /v1/email/sendSalesInvoice. The whole pipeline runs without anyone opening the Big Red Cloud UI.
Call GET /v1/customers/{itemId}/quotes, then POST /v1/email/sendQuote, then POST /v1/salesInvoices to convert and POST /v1/email/sendSalesInvoice
Agent-Driven Bookkeeping via Jentic
An AI bookkeeping assistant connected through Jentic answers a user's natural-language request to 'send Acme Ltd their statement' by searching Jentic, loading the Big Red Cloud sendEmailStatement operation, and executing it with the customer ID. The user's API key stays in the Jentic vault, scoped to the company books, so the agent never sees the raw secret. The same flow scales to invoice posting and receipt logging.
Search Jentic for 'email a customer statement', load Big Red Cloud /v1/email/sendEmailStatement, execute with the customer ID for Acme Ltd
120 endpoints — big red cloud is an irish small-business accounting platform, and its rest api exposes the full ledger model — customers, suppliers, sales and purchase invoices, cash payments and receipts, bank accounts, and nominal accounts — across 120 endpoints under /v1.

Three things that make agents converge on Jentic-routed access.
Credential isolation
Big Red Cloud API keys are stored encrypted in the Jentic vault. Agents call operations by name, and Jentic attaches the key at execution time so the raw secret never enters the agent's context or logs.
Intent-based discovery
Agents search by intent (e.g., 'post a sales invoice', 'email a customer statement') and Jentic returns the matching Big Red Cloud operation with its parameter schema, so the agent calls the correct endpoint without hand-mapping the 120-endpoint surface.
Time to first call
Direct Big Red Cloud integration: 3-5 days mapping the 120-endpoint surface, batch handling, and email dispatch flows. Through Jentic: under 2 hours — search, load schema, execute.

Specific to using Big Red Cloud API API through Jentic.
What authentication does the Big Red Cloud API use?
Big Red Cloud uses an API key generated from the user's Big Red Cloud account. The key is scoped to that company's books and is passed on each request. Through Jentic, the key is held encrypted in the vault and attached at execution time so it never enters the agent's context.
Can I post sales invoices through the Big Red Cloud API?
Yes. POST /v1/salesInvoices accepts a customer ID, line items mapped to nominal accounts, and totals, returning the created invoice record. Use PUT /v1/salesInvoices/batch for end-of-day bulk posts when syncing from an e-commerce platform.
What are the rate limits for the Big Red Cloud API?
Big Red Cloud does not publish hard rate limits in the spec — limits are enforced by the platform per API key tier. For high-volume syncs use the batch endpoints (PUT /v1/customers/batch, /v1/salesInvoices/batch, /v1/cashReceipts/batch) instead of looping single-item calls.
How do I email a customer statement through Jentic?
Run `pip install jentic`, then `await client.search('email a customer statement')`, `await client.load(...)` for /v1/email/sendEmailStatement, and `await client.execute(...)` with the customer ID. Jentic injects the API key from the vault and Big Red Cloud sends the statement directly to the customer's email on file.
Does the API expose VAT and Irish-specific tax handling?
VAT codes flow through the line-item structure on sales and purchase invoices, and the nominal ledger captures the resulting tax control account postings. Use GET /v1/nominalAccounts to enumerate account codes, and GET /v1/nominalAccounts/ledger/{ids} to inspect period activity for VAT control accounts.
Can I retrieve a customer's outstanding balance and transaction history?
Yes. GET /v1/customers/{itemId}/openingBalance and /v1/customers/{itemId}/openingBalanceList return balance information, and GET /v1/customers/{itemId}/accountTrans returns the underlying transactions — useful for chasing aged debt or rendering a statement preview before sending.
