Why teams connect Bill and GitHub

Connect the financial records in Bill with the work happening in GitHub, so both stay current without exports or copy-paste.

Bill holds the financial truth: who the customers are, what they were billed, what they paid. GitHub is where part of the day-to-day work happens, and that work often involves the same customers and transactions. Without a live connection, the two drift apart, and people end up answering questions from stale copies.

Stacksync keeps Bills, Vendors, Invoices, Customers in Bill and Organizations and Teams, Users, Labels and Milestones, Repositories in GitHub in sync, bi-directionally and in real time. Whatever records GitHub keeps and whatever events it produces, the overlap with Bill is mapped field by field, and a change on either side shows up on the other within seconds.

There is no middleware to build, no API rate limits to babysit, and no nightly job that leaves the morning running on yesterday's data.

Common use cases

  • 01 Read approved Bills and their line items into a Postgres warehouse for spend, accrual, and cash-flow reporting without CSV exports.
  • 02 Sync Customers and Invoices from BILL AR into a CRM or ERP so sales and finance see billing and payment status on the account.
  • 03 Two-way sync of GitHub issues with Jira, Linear, or a support system so engineering and customer-facing teams work in their own tools.
  • 04 Mirror repository, PR, and workflow-run data into a Postgres database for engineering-metrics reporting.

Common sync patterns

Where GitHub collects payments or triggers charges: events land in Bill

Payment and charge activity flows into Bill as it happens, so the books reflect reality without manual reconciliation.

Where GitHub tracks people or companies: one identity

A customer's details updated in either system update the other, so finance and the rest of the business stop maintaining two versions of the same customer.

Where GitHub handles customer conversations: billing context in view

Front-line teams see invoice and payment status from Bill next to the customer they are helping, without logging into the finance system.

What you can sync between Bill and GitHub

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Bill objects GitHub objects How this pairing syncs
Invoices Accounts-receivable invoices sent to customers; created and read via /v3/invoices to keep billing status aligned with the ERP or CRM. Organizations and Teams Membership data synced with identity systems and HR directories for access reviews. Invoices is specific to Bill and Organizations and Teams to GitHub — each maps to any object or custom field on the other side.
Customers AR customer master records; mapped to customer/account records in a CRM or ERP so finance and sales share one view. Users Author and assignee identities matched to internal directories. Customers is specific to Bill and Users to GitHub — each maps to any object or custom field on the other side.
Payments Outgoing vendor payments and received customer payments; read for reconciliation and created to schedule bill pay. Labels and Milestones Classification fields mapped to statuses and sprints in external trackers. Payments is specific to Bill and Labels and Milestones to GitHub — each maps to any object or custom field on the other side.
Chart of Accounts GL accounts used to code bills and invoices; typically mastered in the accounting system and written into BILL for consistent coding. Repositories Top-level containers whose metadata and settings syncs read to scope other objects. Chart of Accounts is specific to Bill and Repositories to GitHub — each maps to any object or custom field on the other side.
Bank Accounts Funding and deposit accounts; read to reconcile payments and posted transactions against the ledger. Issues Synced two-way with project trackers and support tools, including labels and assignees. Bank Accounts is specific to Bill and Issues to GitHub — each maps to any object or custom field on the other side.
Vendor Credits and Credit Memos AP and AR adjustments applied against bills and invoices; synced so balances stay accurate on both sides. Pull Requests Review state, status checks, and merge status feed engineering dashboards and workflow tools. Vendor Credits and Credit Memos is specific to Bill and Pull Requests to GitHub — each maps to any object or custom field on the other side.

How changes propagate between Bill and GitHub

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Bill GitHub Sub-second propagation

DetectionBill notifies Stacksync of record changes through webhook events. Webhook event subscriptions (POST /v3/subscriptions) for bills, vendors, payments, invoices, and bank accounts, with polling on.

DeliveryEach detected change is written to GitHub through its API, with automatic retries and rate-limit backoff.

GitHub Bill Sub-second propagation

DetectionGitHub notifies Stacksync of record changes through webhook events. Webhooks with a broad event catalog covering issues, pull requests, pushes, and releases.

DeliveryEach detected change is written to Bill through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Bill: 20,000 requests per developer key per hour; login (POST /v3/login) capped at 200/hour; maximum 3 concurrent requests per developer key per organization. Spend & Expense API is a separate token at 60 calls/token/minute.
  • GitHub: Authenticated REST requests are limited to 5,000 per hour per user; GitHub Apps scale limits per installation.
