Configuring and integrating an established applicant tracking system may require 80-250 hours, roughly $4,000-$12,500 at Vertinus's $49.99 hourly rate. A focused recruiting integration or workflow may take 250-700 hours, about $12,500-$35,000. Building a broad custom applicant tracking platform may require 1,200-4,000 hours or more, about $60,000-$200,000.

Most small businesses should buy an established applicant tracking system rather than reproduce job distribution, accessible applications, candidate communication, scheduling, signatures, security, privacy controls, and product support. Custom development is usually responsible when it closes a specific careers-site, data, approval, reporting, or hiring-handoff gap.

Planning range: $4,000-$12,500 for configuration and integration; $12,500-$35,000 for one focused custom recruiting workflow; $60,000-$200,000+ for a broad platform. Applicant tracking licenses, job boards, assessments, background providers, signatures, messaging, storage, legal review, support, and maintenance are separate.

Configure and integrate an existing ATS: 80-250 hours

This range can cover opening and stage configuration, careers-site styling, application fields, interview plans, evaluation forms, message templates, offer approval, permissions, retention settings, reports, and one human-resources, payroll, calendar, or website integration.

Use the product's supported workflow whenever it meets the hiring process. Unsupported customization can make later upgrades and compliance changes harder.

Focused custom recruiting workflow: 250-700 hours

A first release may include:

  • An accessible careers page and application connected to the ATS.
  • Approved openings, locations, descriptions, and publishing status.
  • Candidate and application matching with reviewed duplicate handling.
  • One role-specific screening, interview, and evaluation path.
  • Scheduling or calendar coordination with visible exceptions.
  • Candidate receipt, preparation, delay, and closure messages.
  • Offer-data approval or document handoff to an established provider.
  • Accepted-candidate handoff to HR, payroll, or onboarding.
  • Stage aging, source, completion, and failed-integration reports.
  • Permissions, audit history, administration, and data export.
  • Testing, pilot, documentation, and hiring-team training.

Broad custom applicant tracking platform: 1,200-4,000 hours or more

Cost grows with many entities and countries, job distribution, agencies, talent pools, candidate portals, resume extraction, assessments, interview scheduling, referrals, offers, signatures, background workflows, onboarding, analytics, mobile access, localization, retention, and many integrations.

Employment, accessibility, equal-opportunity, pay-transparency, immigration, background-check, privacy, automated-decision, and record-retention policies must be supplied and reviewed by qualified professionals. Software can preserve an approved process; it cannot determine whether that process is lawful or fair.

What changes the estimate

Careers site and application

A branded list that opens a hosted application is simpler than searchable jobs, saved progress, localization, accommodations, conditional questions, file processing, candidate accounts, and conversion analytics.

Candidate identity and history

One person may apply for several roles through several sources. Reliable matching, consent-aware imports, reviewed merges, source attribution, historical job versions, and complete exports add work.

Interview and evaluation

One interview and scorecard is narrower than panels, time zones, interviewer availability, independent submissions, structured evidence, rescheduling, accessibility needs, and role-specific plans.

Offers and hiring handoff

Passing an accepted candidate to HR is simpler than compensation approval, document generation, signatures, contingencies, background status, start-date changes, account provisioning, and reconciliation across systems.

Example: careers site through HR handoff

A 90-employee company has an established ATS but needs a branded accessible careers experience, approved-opening sync, one application path, interview coordination, candidate communication, and a verified accepted-candidate handoff to its HR system.

  • Discovery, hiring policy, data mapping, accessibility, and prototype: 40-75 hours.
  • Opening feed, careers pages, search, and application handoff: 55-105 hours.
  • Candidate identity, status, messages, and exception handling: 50-100 hours.
  • Interview scheduling and evaluation workflow: 55-115 hours.
  • ATS-to-HR handoff, reconciliation, and reports: 55-110 hours.
  • Security testing, accessibility testing, pilot, documentation, and training: 50-100 hours.

Total planning range: 305-605 hours, about $15,250-$30,250 at $49.99 per hour, plus the ATS and connected-provider charges.

How to reduce applicant tracking development cost

  • Keep the established ATS as the candidate system of record.
  • Start with one recurring role and one approved hiring path.
  • Use hosted job distribution, signatures, assessments, and background services.
  • Remove application fields that do not support a current decision.
  • Define job-related stages and evaluation criteria before development.
  • Transfer only approved hiring data to HR or payroll.
  • Pilot one opening and reconcile every candidate and message.

The operational guide on applicant tracking software for small business covers openings, applications, screening, interviews, evaluation, offers, privacy, integrations, and rollout.

How Vertinus estimates recruiting workflows

Vertinus charges $49.99 per hour for time actually worked up to the approved estimate. The written scope identifies openings, candidate data, approved stages, roles, messages, integrations, migration, accessibility testing, acceptance, estimated hours, exclusions, and recurring providers.

Send Vertinus one opening from approval through accepted-candidate handoff. Include the ATS, careers site, interviews, offer process, and HR system; we will identify whether configuration, integration, or a focused custom workflow is responsible.
