SAP Business One, AI & software development for Indian SMEs
TopNotch Services is headquartered in Coimbatore, Tamil Nadu. Since 2017 we've helped Indian manufacturers, distributors and traders move from Tally and spreadsheets to SAP Business One, and then added AI, WhatsApp and mobile apps on top.

Do you provide SAP Business One consultants on-site in Coimbatore and Tamil Nadu?
Yes. Our office is in Singanallur, Coimbatore. We regularly work on-site in Coimbatore, Tiruppur, Erode, Salem, Madurai and Chennai, and travel to Bengaluru, Kochi and other cities for workshops and go-live.
Does SAP Business One support GST e-invoicing in India?
Yes. We integrate SAP B1 with the GST e-invoice and e-way bill systems, so IRNs, QR codes and e-way bills are generated directly from your SAP documents without re-typing anything on the portal.
When should an Indian SME move from Tally to SAP Business One?
Common signs are multiple branches or warehouses, inventory in batches or serials, production planning, approval controls, or management reports that take days in Excel. We'll assess whether SAP B1, Zoho or a custom ERP is the right next step.
Do you build websites and mobile apps for Indian businesses too?
Yes. We build SEO-ready websites, e-commerce, customer portals and Android or iOS apps for businesses across India, with or without an ERP connection.
