For Agents
Read and write invoices, bills, payments, customers, suppliers, and ledger accounts across Xero, QuickBooks, Sage, NetSuite, and other accounting platforms through one unified schema.
Use for: Create an invoice for a customer in the connected accounting platform, List all unpaid invoices for a customer across multiple ledgers, Record a bill payment against a supplier invoice, Retrieve the Profit and Loss report for the current quarter
Not supported: Does not handle payroll runs, tax filing submissions, or bank-feed ingestion - use for ledger transactions, invoices, bills, and standard accounting reports only.
Apideck Accounting is a unified API that maps a single schema for invoices, bills, payments, ledger accounts, customers, suppliers, and tax rates onto many downstream accounting platforms such as Xero, QuickBooks, Sage, NetSuite, and FreshBooks. The 95 operations cover the day-to-day finance objects most apps need plus reports like Balance Sheet, Profit and Loss, and Aged Debtors. Apideck routes each call through Apideck Vault, so customer credentials for the underlying platform stay in Apideck's vault instead of being passed in by the calling app.
Install Jentic One Beta
Connect the Accounting API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Accounting API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
Capabilities
What an agent can do with Accounting API.
Create and list invoices with line items, tax rates, and customer references across many accounting platforms
Push and pull bills, bill payments, and supplier records using a normalised supplier schema
Read and write ledger accounts, journal entries, and tracking categories for general-ledger workflows
Fetch the Balance Sheet, Profit and Loss, Aged Debtors, and Aged Creditors reports for any connected ledger
Manage customers, suppliers, payments, credit notes, and expenses with consistent fields across platforms
List company info, locations, departments, and subsidiaries to populate transaction context
Use Cases
Patterns agents use Accounting API for, with concrete tasks.
★ SaaS Billing to Ledger Sync
Push invoices from a SaaS billing system into whichever accounting platform a customer uses (Xero, QuickBooks, Sage, NetSuite, FreshBooks) using a single integration. Apideck's /accounting/invoices endpoint accepts a normalised invoice payload, and the unified API translates it into the native object on the connected ledger. SaaS finance teams typically replace 5+ direct integrations with a single Apideck contract this way.
POST a new invoice to /accounting/invoices with line items totalling $499.00 and the customer reference, then verify the response shows the invoice was created on the connected ledger
Expense and Bill Capture
Forward supplier bills and expenses captured by an OCR or expense-management app into the customer's accounting platform of choice. Apideck's /accounting/bills, /accounting/expenses, and /accounting/bill-payments endpoints accept the unified payload and write to whichever ledger the customer uses. The integration is the same whether the customer runs Xero, QuickBooks, or Sage.
POST a bill to /accounting/bills with the supplier reference and line items, then POST a payment to /accounting/bill-payments to mark it as paid
Financial Reporting Aggregation
Pull Profit and Loss, Balance Sheet, Aged Debtors, and Aged Creditors reports from many customers' ledgers into a single dashboard. Apideck returns each report in a consistent schema so a reporting tool does not need to translate between Xero P&L and QuickBooks P&L manually. Useful for FP&A vendors and lenders who underwrite loans against ledger data.
GET /accounting/profit-and-loss with start_date and end_date for the last quarter and store the returned line items in a reporting database
AI Agent Bookkeeping Assistant
Give an AI agent a tool that can read invoices, create bills, and reconcile payments in whichever accounting platform a customer uses. Through Jentic, the agent searches for an intent like 'create invoice in customer accounting platform' and gets the matching Apideck operation with its input schema. The agent does not need separate integrations per platform.
Search Jentic for 'create accounting invoice', load the /accounting/invoices schema, and execute with the customer reference and line items returned by the upstream conversation

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
All three Apideck headers (Authorization bearer, x-apideck-app-id, x-apideck-consumer-id) are stored encrypted in the Jentic vault and injected at execution time. Per-customer Apideck Vault tokens never enter the agent's prompt or logs.
Intent-based discovery
Agents search by intent (for example 'create accounting invoice' or 'fetch profit and loss') and Jentic returns the matching Apideck operation with its input schema, so the agent does not have to walk the 95-operation reference.
Time to first call
Direct Apideck integration: 1-3 days to wire the three required headers, handle Apideck Vault consumer onboarding, and map errors. Through Jentic: under 1 hour - search, load schema, execute.

FAQs
Specific to using Accounting API through Jentic.
What authentication does the Apideck Accounting API use?
Apideck uses three required headers per call: Authorization with a bearer API key, x-apideck-app-id with your Unify application id, and x-apideck-consumer-id with the end-customer reference stored in Apideck Vault. Through Jentic all three values are stored encrypted in the vault and attached to the request at execution time.
Which accounting platforms does the Apideck Accounting API cover?
Apideck Unify routes the unified accounting calls to downstream connectors including Xero, QuickBooks Online, Sage Business Cloud, NetSuite, FreshBooks, MYOB, and Wave. Use the x-apideck-service-id header to pin the call to a specific connector when a consumer has more than one connected.
Can I create an invoice with the Apideck Accounting API?
Yes. POST to /accounting/invoices with a body that includes the customer_id, currency, due_date, and line_items. Apideck translates the unified payload into the native invoice on the connected platform and returns the created object with the platform's invoice id.
What are the rate limits for the Apideck Accounting API?
Apideck Unify enforces rate limits at both the Unify layer and the underlying connector. The connector-side limit dominates in practice, so a Xero call respects Xero's limits and a QuickBooks call respects QuickBooks' limits. The API returns ConnectorRateLimitError on connector throttling and HTTP 429 on Unify throttling - retry with backoff in both cases.
How do I fetch a Profit and Loss report through Jentic?
Search Jentic for 'get profit and loss report', load the /accounting/profit-and-loss schema, and execute with start_date and end_date. The response returns the report rows in Apideck's unified shape, regardless of whether the connector is Xero or QuickBooks.
Is the Apideck Accounting API free?
Apideck Unify offers a free tier with capped requests; production use is billed per consumer connection. See https://www.apideck.com/pricing for current tiers and contact sales@apideck.com for volume pricing.
