When a hiring manager presses the hire button in BambooHR, the new employee’s information appears in ADP automatically — nobody retypes it. Flexspring connects BambooHR to ADP directly, so new hires, employee changes, approved time off and payroll details move between the two systems in near real time. Your team gets fewer payroll corrections, faster onboarding, and an end to double-data entry between HR and payroll.
Flexspring builds, hosts, and monitors the connection for you. There are no files to upload and nothing for your team to maintain. Integrations covering the essential fields go live in 4–6 weeks; custom builds with extra fields, custom tables and business logic take 8–10 weeks. Every use case is built separately, including sending ADP payroll data back into a custom table in BambooHR so your team can view HR and payroll information in one place. With Flexspring, you only pay for the use case or use cases you need.
Everything below flows from BambooHR to ADP automatically. Payroll data flows the other way — from ADP back into a custom table in BambooHR, so your team can view HR and payroll information in one place.

Flexspring iPaaS does not store employee data beyond temporary transaction logs, and meets SOC 2, GDPR and ISO 27001 standards.

Read the full case studyA lot of people arrive here comparing the two products. If you’re deciding which single system to buy, that’s a real decision and this guide won’t make it for you.
But many teams don’t choose. They keep BambooHR as the HR system of record — where managers hire, update records and approve time off — and ADP for payroll. That works well, right up until someone has to keep both in sync by hand. Disconnected apps are the problem this data integration solves: BambooHR stays the place people work, and ADP gets clean data on time without anyone retyping it.
With data integration, new hires, employee changes, approved time off and payroll details move from BambooHR to ADP automatically, and ADP payroll data flows back into a custom table in BambooHR. Flexspring builds the integration to match your custom fields and business rules, then hosts and monitors it.
You decide which information you want to sync, and a data integration expert like Flexspring maps every field between the two systems and builds the connection. Custom integrations by Flexspring include unlimited custom fields and unlimited business rules. There is nothing for your team to install or maintain.
With data integration, new hires sync, including your custom fields, plus employee changes and rehires, terminations and leave of absence, and approved paid time off. You can also add one-time payments, direct deposit details, departments and locations, emergency contacts, benefits and allowances, time and attendance, federal and state tax details, post-hire details such as SSN and date of birth, and ADP payroll data into a custom table in BambooHR.
Flexspring builds, hosts, and monitors the connector. Integrations covering the essential fields go live in 4–6 weeks. Custom builds — more than five custom fields, custom tables, country filters or specific business rules — take 8–10 weeks. The guide explains which one fits your setup. Custom integration by Flexspring includes unlimited custom fields and unlimited business rules. Flexspring does all the data mapping, so no internal IT resources are needed.
Flexspring does not store employee data beyond temporary transaction logs, and does not require anyone to handle the data manually. Flexspring meets SOC 2, GDPR and ISO 27001 standards.
No internal IT resources are needed to create your data integration. Flexspring’s team builds the integration to your requirements and monitors it afterwards, including handling API changes from either vendor. Your part is deciding which use cases you need and confirming Flexspring’s recommendations for how your fields should map.
With data integration, when a hiring manager presses the hire button in BambooHR, the new employee’s information appears in ADP automatically — nobody retypes it. Your team gets fewer payroll corrections, faster onboarding, and no double-data entry between HR and payroll. One biopharmaceutical company’s HR staff saves 25 hours a month.
The best way to connect BambooHR to ADP depends on your data and business requirements. A standard connector can work for simple data flows, while custom fields and unique business rules require a tailored integration. If you go the custom route, you can build the integration yourself or choose a managed integration like Flexspring’s — built and maintained for you, which is typically faster and cheaper.
