Explore 20 questionsThe short answer
What matters for your decision
Hirebase product materials identify Paychex as a payroll connection target. Hirebase calculates wages from attendance and approved time, while Paychex remains the payroll processor. Paychex publishes REST APIs and OAuth-based developer resources, but those vendor materials do not establish which Paychex interface or fields a Hirebase implementation uses.
Confirm the Paychex service in use
Paychex offers multiple payroll and HR services and a developer API program. Hirebase identifies Paychex as a connection target without publishing a single product-specific mapping. Confirm the Paychex service, account, country, and intended payroll workflow first.
Set the boundary between time calculation and payroll
Hirebase describes verified attendance, approved time adjustments, wage calculation, and handoff. Paychex processes payroll and disburses wages. Tax filing, deductions, and other provider-owned tasks remain outside the Hirebase calculation boundary unless separately documented.
Agree identifiers and pay fields
Proposed checks include employee and company identifiers, pay-period dates, approved hours or calculated pay elements, location or job coding, and result status. No complete Hirebase-to-Paychex field map is published, so review every field with payroll and integration owners.
Test account authorization and reconciliation
Paychex's developer center describes REST APIs with OAuth 2.0 and JSON request and response data. Verify the exact Paychex app authorization and whether the Hirebase path uses that interface. Then compare a controlled batch with Paychex's accepted records and define correction and escalation owners.

20 of 20 questions
Does Hirebase name Paychex as a payroll connection?
Yes. Hirebase product materials list Paychex as a payroll connection target. Confirm the chosen Paychex product and scope.
Link to this answerDoes the connection specifically support Paychex Flex?
The general Hirebase materials name Paychex but do not specify a particular Paychex product. Confirm Paychex Flex or another service during technical discovery.
Link to this answerDoes Paychex publish integration APIs?
Yes. Paychex's developer center documents a REST API program and OAuth 2.0 authorization. That describes Paychex's interface, not the specific Hirebase connection.
Link to this answerDoes Hirebase's Paychex connector use OAuth?
The public Hirebase product pages do not identify the transport or authentication method. Confirm how credentials and authorization work for the selected implementation.
Link to this answerWhat does Hirebase do before the Paychex handoff?
Hirebase documents wage calculation from attendance and approved time. The receiving payroll provider remains responsible for processing and disbursement.
Link to this answerDoes Hirebase send net pay to Paychex?
The public materials do not define the exact payload and do not establish net-pay processing. Confirm whether the handoff contains hours or configured wage values.
Link to this answerCan the handoff include location or job codes?
The Hirebase pages do not publish a complete Paychex mapping. Confirm supported coding dimensions for the chosen Paychex product and pay workflow.
Link to this answerWho handles tax withholding and payment?
The employer and its payroll provider own payroll processing and statutory responsibilities. Hirebase does not file statutory forms or disburse wages.
Link to this answerCan approved time adjustments be included?
Hirebase describes approved time changes as part of payroll readiness. Verify the exact representation in the Paychex batch or connection.
Link to this answerWhat is the Paychex transfer cadence?
No universal cadence is stated in Hirebase's public material. Agree cutoff, transfer timing, and late-adjustment handling with payroll.
Link to this answerDoes Paychex's API guide document Hirebase retry behavior?
No. Paychex documents its own API behavior; it does not document Hirebase retries. Agree retry, failure alerting, and replay responsibilities for the deployed integration.
Link to this answerWhat if Paychex rejects a row?
Public product materials do not describe a universal rejection flow. Define the owner, source correction, resubmission method, and reconciliation record during implementation.
Link to this answerCan the connection handle multiple Paychex companies?
Hirebase does not publish multi-company limits for this connector. Include legal entities and account boundaries in the integration design.
Link to this answerWhat should IT review for API access?
If API access is used, review OAuth client authorization, least-privilege scope, secret custody and rotation, environment separation, and audit ownership.
Link to this answerCan Paychex test data be used before go-live?
The Paychex developer program has developer resources; confirm test account availability and whether Hirebase can support that environment for the selected connection.
Link to this answerHow should payroll reconcile a pilot?
Compare approved Hirebase records and calculated totals with Paychex's accepted population and any rejected rows for the same period.
Link to this answerDoes the Paychex API prove a certified Hirebase integration?
No. Vendor API documentation is not evidence of Hirebase certification, connector internals, or a particular implemented field mapping.
Link to this answerCan Paychex send changes back into Hirebase?
A bidirectional flow is not specified in the Hirebase product material. Confirm direction and which system owns each field.
Link to this answerWhat should be written into Paychex integration acceptance criteria?
Document the Paychex product, data fields and direction, access model, representative test results, rejection owner, cutoff, reconciliation, and ongoing support responsibilities.
