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, and make our own products: Collie, xDocs and HeyInvoice.

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.

Can HeySheep help us comply with InvoiceNow?

Yes. HeySheep's HeyInvoice (einvoice.heysheep.sg) sends and receives e-invoices over Singapore's InvoiceNow (Peppol) network with GST validation and IRAS submission, and connects to existing ERP and accounting systems through its API.

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.
