Run the business. Sahaya runs the books.

Sign up at app.sahayaos.com and the wizard walks you through four short steps:

1. Business. Pick what kind of business you run — Service, Retail/Kirana, Trading/Distribution, Manufacturing, Restaurant/Cafe, or Professional Practice. This sets your defaults: navigation, invoice format, GST behaviour.
2. Details. Choose your state and enter your GSTIN (you can add it later — but with it, place-of-supply and CGST/SGST-vs-IGST are decided correctly for every invoice).
3. Agreement. Three plain-language points about your data: encrypted servers in India under the DPDP Act, never sold or shared, exportable or deletable by you at any time. Tick and continue.
4. First step. Sahaya shows the modules it picked for your business type — tap Adjust to add or remove any (Stock tracking, Recurring invoices, and so on). Then it points you at your first real action: create an invoice, add an item, or upload a bill.

Every morning, /home answers three questions without you clicking anything:

1. What happened while you were away? The top line counts what Sahaya did overnight — bills read, entries posted, reminders sent. "Behind the scenes" shows the full log of who did what, when.
2. What needs you? The "Needs you" queue lists only decisions waiting on a human — a held bill, an anomaly, an approval. Use J/K to move and ↵ to decide. Empty queue? It says so: "Enjoy the quiet."
3. Am I okay on cash? The right rail shows your 30-day cash movement and today's schedule at a glance.

The single biggest change from your old software: nobody types purchase bills. Set up the three intake channels once:

WhatsApp — for you and trusted staff

1. Open Settings → WhatsApp.
2. Add each phone allowed to send bills — number plus a label like "Owner — Ramesh". Only phones on this list can post to your books; strangers get politely refused.
3. Save Sahaya's WhatsApp number in those phones. From then on: photograph the bill, send, done.

QR code — for everyone else

1. Open Settings → Mobile QR and print the QR code. Stick it at the counter, the godown, the site office.
2. Anyone scans it, taps the camera button, photographs the bill. No app, no login. It lands in your inbox already read.

Then review, don't type

Everything arrives in Documents with the supplier, invoice number, date, and amounts already extracted. Open one, correct anything the AI misread, press Post to ledger. Bills above your approval limits wait in Approvals — with trust signals like PO matched or Duplicate suspected — until you or the right person approves.

Go to Settings → Team. Two ways to add people:

1. Email invite: enter their email, pick a role, click Send invite. They set a password on one page and land straight in your company.
2. Join link (easier): in the join-links section, pick the role, give the link a label, set an expiry, and click Create link. Share it on WhatsApp — anyone who opens it joins with that role. Revoke the link any time.

Each member card shows a plain-sentence consequence of their role, their module access, a full history of changes, and a Revoke button. Removed someone by mistake? Restore re-grants the same role with history intact.

Reports has everything your CA asks for — and every number is clickable down to the entries behind it. The ones worth a weekly look:

1. Open Period close and pick the month. Sahaya runs every pre-flight check your CA would — and lists blockers to fix and warnings to acknowledge.
2. When the banner says Ready, click Lock period. From that moment nothing new can land in that month unless someone unlocks it — with a recorded reason.
3. Your CA signs off from their own login; every signature is logged with name, time, and note. That's your audit trail, built as you go.
