FastBusinessAPI vs Checkify
Checkify validates business data. FastBusinessAPI stores the business profile.
Checkify is built around Australian validation APIs, including ABN lookup, ACN lookup, company name checks, business name checks, email validation, phone validation, and sanctions screening. FastBusinessAPI is built for users who want to search an ABN, generate a richer Australian business profile, store it, and come back to that business data later.

Quick answer
Use Checkify when you need validation endpoints. Use FastBusinessAPI when you need stored business profiles.
Checkify is a strong fit when the job is validation: checking ABNs, ACNs, emails, phone numbers, business names, or sanctions lists through API endpoints. FastBusinessAPI is built for a different workflow: search an ABN, generate a more complete Australian business profile, save it, and reuse that profile later for supplier checks, onboarding, research, or internal records.
Feature comparison
Checkify compared with FastBusinessAPI.
The main difference is product focus. Checkify is broader and validation-led. FastBusinessAPI is narrower and profile-led, focused on ABN-based Australian business records that users can store, revisit, and use as business context.

|---|---|---|
| Primary focus | Australian validation APIs across ABN, ACN, names, email, phone, and sanctions. | ABN-based Australian business profile search, generation, storage, and reuse. |
| Best for | Developers who want multiple validation endpoints in one platform. | Users who want to look up an ABN and store a richer business profile. |
| ABN lookup | Validates ABNs and returns ABR entity data, GST status, business names, ACN, and dates. | Uses ABN lookup as the starting point for a fuller stored business profile. |
| ACN lookup | Offers ACN lookup with ASIC company records, former names, addresses, documents, and status. | Can store ACN as part of a business profile when available. |
| Profile storage | Primarily API and bulk validation workflow. | Built around saved business profiles and recent searches. |
| User experience | Developer/API-first validation experience. | Front-facing SaaS experience for searching, reviewing, saving, and returning to business profiles. |
| Business context | Focused on validation and official lookup data. | Designed to add business context such as names, website, industry, location, descriptions, sources, and profile details. |
| Supplier checks | Useful for validating supplier ABNs and related records through API or bulk workflows. | Useful for reviewing suppliers and storing reusable business profiles for later checks. |
| Bulk workflow | Supports bulk CSV processing for some endpoints. | More focused on individual ABN search, saved records, and stored profile workflows. |
| Ideal customer | Technical teams needing broad validation infrastructure. | Businesses, operators, bookkeepers, and teams that want a simple SaaS for ABN-based business records. |
The real difference
Checkify is broad validation infrastructure. FastBusinessAPI is focused business profile software.
Checkify is endpoint-led.
It is useful when a team wants APIs for validating different data types, including ABNs, ACNs, emails, phone numbers, names, and sanctions screening.
FastBusinessAPI is profile-led.
It is built around the idea that an ABN search should create a useful stored business profile, not just a temporary validation response.
The use case is simpler.
FastBusinessAPI focuses on making Australian business lookup and profile storage easy for users who do not want a broad validation stack.
Why FastBusinessAPI
Built for teams that want to find, save, and reuse Australian business profiles.
FastBusinessAPI is not trying to be every validation endpoint. It is focused on one clear workflow: search by ABN, create a useful business profile, store it, and make that data easier to revisit.
Saved business records
Keep track of businesses you have already searched instead of repeating the same lookup again later.
Simple SaaS workflow
Designed for users who want a clear front-facing product, not just developer endpoints and validation documentation.
Supplier review context
Store ABN, ACN, business name, website, location, industry, descriptions, and source-style context where available.
Recent search history
Return to previous searches and completed profiles so business checks become easier to manage over time.
Narrower, clearer positioning
Instead of offering many unrelated validation categories, FastBusinessAPI focuses on Australian business profile data.
