By fetching the customer's chart of Accounts and Tax Rates via Truto, expenses land in the correct GL accounts with proper tax treatment. - **Sync invoices and payments from field service or vertical SaaS** — Field service, project management, or vertical SaaS platforms can generate Invoices in Zoho Books when jobs are completed, syncing Contacts, Items, and Tax Rates automatically. When customers pay on-site or online, a Payment record closes the invoice without any manual bookkeeping. - **Push payroll journal entries into the general ledger** — Payroll and HR platforms can post multi-line Journal Entries to Zoho Books after each pay run, correctly debiting salary and benefits expense accounts and crediting cash and liability accounts. This eliminates hours of manual entry and reduces the risk of misclassified payroll transactions. - **Keep procurement and AP in sync across platforms** — Procurement and supply chain SaaS companies can create Purchase Orders in Zoho Books when requisitions are approved and issue Vendor Credits for returns or adjustments. This keeps accounts payable accurate without requiring finance teams to duplicate work across systems. - **Reconcile external payment data with Zoho Books records** — Payment processing and billing platforms can fetch Payments and Transactions from Zoho Books to surface payment status in their own UI, or push settlement data back for bank reconciliation. This gives shared customers a single source of truth for cash flow. ## What you can build - **GL account mapping interface** — Fetch your customer's chart of Accounts from Zoho Books so end users can map categories, cost centers, or departments in your product to the correct ledger accounts. - **Automated invoice generation** — Create Invoices in Zoho Books with the correct Contacts, Items, and Tax Rates whenever a deal closes, a job completes, or a subscription renews in your platform. - **One-click expense sync** — Push approved Expenses from your spend management or T&E product directly into Zoho Books, tagged to the right employee, vendor, account, and currency. - **Payroll journal entry posting** — Automatically create balanced, multi-line Journal Entries in Zoho Books at the end of each payroll cycle, covering wages, taxes, benefits, and employer contributions. - **Payment status dashboard** — Read Payments and Invoice data from Zoho Books to show your users real-time collection status — which invoices are paid, partially paid, or overdue — without leaving your app. - **Credit note and vendor credit automation** — Automatically issue Credit Notes or Vendor Credits in Zoho Books when returns, refunds, or billing adjustments occur in your platform, keeping AR and AP balances accurate. ## FAQs ### What authentication method does Zoho Books use? Zoho Books uses OAuth 2.0 for API authentication. Truto handles the full OAuth flow — including token refresh — so your end users can securely connect their Zoho Books organization without you managing credentials or token lifecycle. ### Which Zoho Books data models are available through Truto's Unified Accounting API? Truto's Unified Accounting API supports Accounts, Company Info, Contacts, Credit Notes, Currencies, Employees, Expenses, Invoices, Items, Journal Entries, Payments, Purchase Orders, Tax Rates, Transactions, and Vendor Credits. Users are available through the Unified User Directory API. ### Does Truto handle pagination and rate limits for Zoho Books? Yes. Truto manages pagination automatically when fetching large datasets like Invoices or Transactions. It also respects Zoho Books' API rate limits and handles retries, so you don't need to build throttling logic yourself. ### Can I read and write data, or is the integration read-only? Truto's Unified Accounting API supports both read and write operations on supported models. You can fetch existing records like Accounts and Tax Rates for mapping, and create new records like Invoices, Expenses, Journal Entries, and Purchase Orders. ### How does Truto handle Zoho Books' multi-currency support? The Unified Accounting API includes a Currencies model, allowing you to fetch the currencies configured in your customer's Zoho Books organization. This lets you correctly reference currency codes when creating Invoices, Expenses, or other financial records. ### What if I need a Zoho Books capability not covered by the Unified API? Truto builds additional tools and proxy API access on request. If you need access to Zoho Books endpoints beyond the standard unified models — such as recurring invoices or custom modules — reach out and the Truto team can extend coverage for your use case.
