We build the software your business runs on, and automate the data in between.

Point of sale, pharmacy, billing and back-office systems, plus the work that moves and cleans data between the tools you already use. Try it on the map: connect a source to where it should go.

Replica screens are working copies with sample data.

Two tools behind our lead generation work: a crawler that works through business websites in queued jobs, and an email checker that scores each address before anyone sends to it.

Instead of: Opening websites one tab at a time, and sending to email addresses nobody has checked.

  • Crawls the websites you give it and follows their links, within include and exclude patterns and a depth limit
  • Queues crawl jobs across workers and retries pages that fail
  • Live stats, page status and logs for every crawl
All features4 more
  • Checks each email for syntax, mail servers, disposable domains and suspicious patterns
  • Flags role addresses such as info@ when that rule is switched on
  • Whitelists, blacklists and check rules per project, with a risk score for each address
  • A contact extractor for emails, phones and social links is built, and not yet wired into the crawl

Questions people ask

Do you have packages or a price list?

No. Every project gets a written quote before work starts, with the scope, timeline and price. Clients in Bangladesh are quoted in Bangladeshi Taka (BDT) and clients in Australia in Australian dollars (AUD).

Where are you based?

ALT SHIFT UP PTY LTD is registered in New South Wales, Australia, at Unit 10, 37 Crown Street, Granville NSW 2142, Australia. We work remotely and deliver everything digitally.

Will you work with data we do not own?

No. We work only with data and systems that you own or are authorised to use, and we decline work that needs bypassing logins, paywalls or a website’s terms.

Who owns the software you build?

You do. Once the project is paid in full, the custom code, configuration and documents made for you are yours. We keep our own general-purpose tools and libraries.

What do you need from us to start?

A short description of the work your team does by hand, a sample of the files or screens involved, and one person who can answer questions and test what we build.

Do you look after the software after launch?

If you want us to. Maintenance is agreed separately, month to month, and you can cancel at the end of any month.
