FAQ

HeySheep, in short.

What does HeySheep do?

HeySheep is a Singapore software development and AI automation company. We build custom software, web and mobile apps, automate manual business processes with AI, provide dedicated and forward deployed engineering teams, help businesses get found on search engines and AI assistants (SEO, AEO and GEO), and make our own products: Collie, the AI at the centre, and the Hey family — HeyDocs, HeyInvoice and HeyShop.

Where is HeySheep based?

HeySheep is headquartered at 10 Anson Road, International Plaza, Singapore, with its own R&D engineering centre in Da Nang, Vietnam — one hour behind Singapore, so the teams work the same business day.

Does HeySheep offer offshore software development in Vietnam?

Yes. HeySheep builds dedicated offshore development teams at its own Da Nang office, managed and contracted from Singapore. Teams include full-stack and mobile engineers, QA, DevOps and project managers.

Can HeySheep help my business automate manual work with AI?

Yes. We map where your team re-types data, chases approvals or reconciles spreadsheets, then automate it with integrations, document AI and agents that ask a person before acting. A first automation is typically live within weeks.

Does HeySheep build AI agents and AI software?

Yes. HeySheep is an AI development company: we build AI agents, document AI and chatbots into your existing systems, with a person approving anything that moves money or data. Our own product, Collie, gives every department a private AI agent running inside your office.

What are HeySheep's forward deployed engineers?

Forward deployed engineers (FDEs) are senior HeySheep engineers who join your team — on-site in Singapore or in your daily channels — learn the problem first-hand and ship a working solution with AI-assisted development, staying until the outcome is live.

Can HeySheep help us comply with InvoiceNow?

Yes. HeySheep's HeyInvoice sends and receives e-invoices, credit notes and purchase orders over Singapore's InvoiceNow (IMDA Peppol) network through SESAMi, an IMDA-accredited Access Point, and transmits invoice data to IRAS under the GST InvoiceNow requirement — alongside your existing accounting or ERP system. Software vendors and resellers can also offer it under their own brand (white label).

How do we start a project with HeySheep?

Send a message on the contact page or WhatsApp. A senior engineer replies within one business day, then a short discovery call maps the work and you receive a written scope and fixed plan.
