Why teams connect Bill and Twilio

Connect the financial records in Bill with the work happening in Twilio, 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. Twilio 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 Chart of Accounts, Bank Accounts, Vendor Credits and Credit Memos, Bills in Bill and Incoming Phone Numbers, Outgoing Caller IDs, Accounts, Roles in Twilio in sync, bi-directionally and in real time. Whatever records Twilio 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 Write Vendors created during ERP onboarding into BILL so new payees are ready to pay without manual re-entry.
  • 02 Read Payments and payment status into a reconciliation database once bills are marked paid in BILL.
  • 03 Push Twilio usage records into a finance database for per-customer communication cost allocation.
  • 04 Trigger outbound messages by writing rows to a synced database table instead of calling the Twilio API directly from application code.

Common sync patterns

Where Twilio 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.

Where Twilio 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 Twilio 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.

How changes propagate between Bill and Twilio

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 Twilio 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 Twilio through its API, with automatic retries and rate-limit backoff.

Twilio Bill Sub-second propagation

DetectionTwilio notifies Stacksync of record changes through webhook events. Status callback webhooks per message and call, plus polling of resource lists for backfill.

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.
