Why integrate with Bill
Common scenarios for SaaS companies building Bill integrations for their customers.
Automate vendor payouts from your vertical SaaS platform
If your platform manages workflows that end in paying vendors, contractors, or suppliers, integrating with Bill lets your users push approved payables directly into their Bill account for payment execution — no manual re-entry required.
Pull real-time AP data for cash flow forecasting
FP&A and treasury tools need visibility into upcoming and outstanding payables. By reading Bills and Payments from your users' Bill accounts, you can power accurate cash burn forecasts and liquidity dashboards without asking users to export CSVs.
Sync procurement approvals into Bill for payment execution
Procurement and spend intake platforms handle the request-and-approve workflow, but the actual money movement happens in Bill. Integrating lets your users seamlessly hand off fully coded bills to their finance team for final payment release.
Stage bills automatically from industry-specific workflows
Practice management, construction, or property management SaaS platforms generate payable events as part of their core workflow. Pushing these as pre-coded Bills into your users' Bill accounts eliminates double-entry and accelerates payment cycles.
Issue invoices and track receivables through Bill's AR capabilities
Subscription billing or usage-based billing platforms can create customer invoices in Bill's Accounts Receivable module, giving end users a low-friction ACH payment option and keeping AR data in sync with their general ledger.
What You Can Build
Ship these features with Truto + Bill
Concrete product features your team can ship faster by leveraging Truto’s Bill integration instead of building from scratch.
One-click vendor creation and network lookup
Automatically create vendors in your users' Bill accounts and leverage the Bill Network to skip manual bank detail collection when the vendor already exists.
Automated bill staging with document attachment
Push fully coded bill line items along with the original invoice PDF into Bill so finance teams can review and approve without context-switching.
Payment status webhook listener
Subscribe to Bill's payment status webhooks to reflect real-time statuses like Scheduled, Cleared, or Failed directly in your product's UI.
Accounts payable sync for cash flow dashboards
Pull unpaid, scheduled, and historical bills and payments from Bill to build real-time cash position and burn rate visualizations.
Virtual card provisioning and budget controls
Use Bill's Spend & Expense APIs to generate virtual cards for employees and enforce per-department or per-project spending limits from within your platform.
Embedded Bill workflows via Bill Elements
Drop Bill's embeddable UI components into your product so users can complete approval and payment flows without leaving your application.
How It Works
From zero to integrated
Go live with Bill in under an hour. No boilerplate, no maintenance burden.
Link your customer’s Bill account
Use Truto’s frontend SDK to connect your customer’s Bill account. We handle all OAuth and API key flows — you don’t need to create the OAuth app.
We handle authentication
Don’t spend time refreshing access tokens or figuring out secure storage. We handle it and inject credentials into every API request.
Call our API, we call Bill
Truto’s Proxy API is a 1-to-1 mapping of the Bill API. You call us, we call Bill, and pass the response back in the same cycle.
Unified response format
Every response follows a single format across all integrations. We translate Bill’s pagination into unified cursor-based pagination. Data is always in the result attribute.
FAQs
Common questions about Bill on Truto
Authentication, rate limits, data freshness, and everything else you need to know before you integrate.
What authentication method does the Bill API use?
Bill's v3 API uses OAuth 2.0 for authentication. Truto handles the full OAuth flow, token refresh, and credential storage so your team doesn't need to manage auth lifecycle per connected account.
Is the Bill integration available as a prebuilt Unified API on Truto?
Bill is not yet mapped to a Truto Unified API. It is built on request — contact Truto to scope the integration, and the team will build and maintain the connector tailored to your use case.
Does Bill support webhooks for real-time data updates?
Yes. Bill's v3 API supports webhooks for key events, most notably payment status changes (Scheduled, Cleared, Voided, Failed). This lets your application react in real time rather than polling.
What are the core API objects available in Bill's v3 API?
The primary objects include Vendors, Bills, Payments, Documents, Customers, Invoices (AR), and Spend & Expense resources like virtual cards and budgets. These cover both AP and AR workflows.
Are there rate limits on the Bill API?
Yes, Bill enforces rate limits on its v3 API. Truto manages request throttling, pagination, and retries on your behalf to ensure your integration stays within limits without dropped requests.
Can I attach invoice documents when creating a Bill via the API?
Yes. Bill's v3 API has a dedicated documents endpoint that lets you upload PDFs or images and associate them with a Bill object, so finance teams see the source invoice alongside the coded payable.
