Why teams connect Bill and Demandbase

Put revenue reality behind every campaign: Bill and Demandbase share the same customers, contacts, and billing status in real time, in both directions.

Bill records the money — who pays, how much, and whether they are current; Demandbase decides who hears from the business and what they hear. The two overlap wherever the same customers and contacts matter to both, and when that overlap is bridged by CSV exports or an overnight batch, campaigns target on stale billing data and finance works from lists marketing has already changed underneath it.

Stacksync syncs Vendors, Invoices, Customers, Payments in Bill with Activities, Campaigns, Account & Person Lists (Audiences), Company Details (B2B enrichment) in Demandbase field by field, in real time, and in both directions. You decide which system owns which fields — finance keeps the revenue and payment truth, marketing keeps consent and engagement — and Stacksync keeps every copy consistent and resolves conflicts by rules you set.

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 Sync Opportunities and Activities two-way so CRM deal and engagement data flows into Demandbase reporting and Demandbase-calculated insights flow back to the warehouse.
  • 04 Subscribe to Demandbase company and person change webhooks - firmographic updates, M&A, and leadership or employment changes - and land them in an operational store for real-time account alerts.

Common sync patterns

Where Bill tracks lifecycle state: keep Demandbase current

Trial, renewal, churn, or payment state from Bill updates the contact in Demandbase, so lifecycle campaigns and audience suppression run on current billing reality.

Consent and contact details stay aligned

Email, phone, address, and opt-out flags kept in either system stay consistent in the other, so every send and record honors the latest preferences.

Revenue and billing signals reach the audience

Plan tier, spend, or payment status from Bill lands on the matching record in Demandbase, so segments and targeting reflect who actually pays and how much.

What you can sync between Bill and Demandbase

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 Demandbase objects How this pairing syncs

How changes propagate between Bill and Demandbase

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

Demandbase Bill Sub-second propagation

DetectionDemandbase notifies Stacksync of record changes through webhook events. Subscription API webhooks - company firmographic, company news, family-tree (ownership), and person employment-change alerts to a configurable URL.

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.
  • Demandbase: Credit-based per API call; bulk jobs accept up to 10,000 records per submission, CSV uploads up to 5GB, and result URLs stay valid 24 hours; subscription alerts page up to 5,000 entities and list endpoints up to 100 per page.
