The situation
Your business has outgrown spreadsheets
Nothing here is a failure of effort. It is what happens when sales, stock and GST live in different files.
Stock lives in three places
One sheet per warehouse, none of them current by Friday afternoon.
GST is a separate job
Invoices are raised in one system and re-keyed somewhere else for filing.
Invoices go out by hand
Download the PDF, open WhatsApp, find the customer, attach, send. Every time.
Transfers are guesswork
Stock in transit between branches is invisible until it arrives.
Customer pricing is memory
Each buyer has their own rate, and only one person in the office knows them all.
Purchases and sales never meet
What you bought and what you sold are reconciled by hand, monthly, at best.
Receivables surface too late
You find out an invoice is 60 days overdue when you go looking for it.
No stock traceability
When a buyer asks which batch they received, there is no answer in the file.
AVS Invoice brings the whole workflow into one place.
The workflow
From purchase order to payment. From quote to cash
Two document chains, one stock ledger between them. A receipt creates a lot; a sale consumes it. That single connection is what makes the rest of the numbers agree.
Sales
- Quote
- Sales order
- Invoice
- Payment received
InventoryA receipt creates a lot. A sale consumes it.
Purchases
- Purchase order
- Bill
- Payment made
Sales
Everything between the quote and the cash
- Quotes — convert to a sales order or straight to an invoice.
- Sales orders — commit stock before you ship it.
- Invoices — GST-correct, numbered by your own series.
- Credit notes — returns and corrections that restore stock.
- Recurring invoices — weekly to yearly schedules that never double-bill.
- Payments received — full or part, allocated across invoices.
- Price lists — customer-specific rates, applied automatically.
- Payment terms — due dates that calculate themselves.
- Customers — with GSTIN, addresses and running balance.
- Credit control — per-customer credit limits, with every override logged.

Purchases
Keep purchasing as organised as selling
- Purchase orders — what you asked for, at what price.
- Bills — received against the order, variance visible.
- Debit notes — vendor returns and rate corrections.
- Payments made — allocated across bills.
- Vendors — with GSTIN and running payable.
- Expenses — costs that never had a purchase order.
- PO-to-bill variance — where you were billed something other than what you ordered.
- Purchase price trend — what an item has cost you over time.
- TDS — section-wise on bills, with 26Q payable and 26AS receivable reports.
- MSME payables — bills to MSME vendors flagged before 45 days.

Inventory
Inventory visibility at the level your business actually needs
- Stock on hand — by item, variant and warehouse.
- FIFO lots — every receipt becomes a costed, traceable lot.
- Stock movements — an append-only ledger of every change.
- Stock transfers — between warehouses, with in-transit visibility.
- Stock adjustments — damage, shrinkage and recounts, recorded in the ledger.
- Stock valuation — weighted-average cost, per location.
- Reorder suggestions — what to buy before you run out.
- Barcode labels — printed per lot for the floor.

Customer portal
Your customers stop calling to ask for invoices
- Their invoices — current and historical, downloadable.
- Their ledger — a running statement of account.
- Their payments — what has been received and against what.
- Pay online — UPI, card or netbanking through your own Razorpay, recorded against the invoice.
- Pay links — one link per invoice, with a UPI QR and an "I've paid" button.
- Quotes and orders — accept quotes and approve sales orders from the portal.
- Self-ordering — retailers order from your catalogue at their own price list.

Reports

- GST filing — return-ready summaries from posted invoices.
- Stock movement ledger — every in and out, traceable to a document.
- Stock valuation — what your inventory is worth, by location.
- Customer and vendor ledgers — running account for either side.

Team
Give every team member exactly the access they need
- Owner — full access, including billing and organisation settings.
- Admin — everything Owner can do day to day, including billing. Deleting the organisation stays with the Owner.
- Accountant — books, payments, GST and reports.

- Purchase — orders, bills, vendors, expenses.
- Viewer — read-only across every module.
- Audit log — who did what, on which document, when.

Stop managing your business across disconnected tools.
GST
GST shouldn't be a separate workflow
Tax is decided while the invoice is being written, not afterwards. Place of supply, HSN and rate come from the record itself, so filing reports are a read of your data rather than a rebuild of it.
Tax on the invoice
Tax is decided while the invoice is written
- GSTIN validation — captured and checked on every customer and vendor.
- HSN / SAC — held on the item, applied to every line automatically.
- Place of supply — drives CGST/SGST versus IGST without anyone deciding.
- GST rates — per item, from 0% to 28%, plus your own.
- Multiple GSTINs — several registrations in one organisation; the right one on every document.

E-invoicing
E-invoicing, without leaving your workflow
Generate the IRN from the same screen you raised the invoice on. AVS builds and validates the payload, submits it through a GST Suvidha Provider or directly to the NIC IRP, stores the signed response and tracks the status. No second portal, no re-keying, no CSV.
- IRN generation — from the invoice you already created.
- Signed QR code — stored against the document and printed on the PDF.
- Cancellation — with reason code and remark, inside the window.
- E-way bill — generate by IRN, update vehicle, extend validity.
- Status tracking — generated, cancelled or failed, in the E-Invoice Success/Failure report.
- Per-GSTIN credentials — each registration connects with its own credentials.

Your business runs on WhatsApp. Your invoices should too
Send the invoice as a PDF on WhatsApp the moment it is raised, from the invoice screen. Quotes, purchase orders, ledgers and payment reminders go the same way, through approved message templates on the WhatsApp Business platform.
- Invoice sent — PDF attached, delivered to the buyer's phone.
- Payment reminder — before and after the due date, with a pay link.
- Quote sent — get a price in front of a buyer while they are still asking.
- Purchase order sent — the same flow, pointed at your vendors.
- Customer ledger — a full statement of account, on request.
- Outstanding balance — what a buyer owes you, in one message.
- Shared inbox — two-way conversations per contact; replies feed collections.

FIFO lot tracking
Don't just track stock. Track where it came from
Every receipt becomes a lot with its own cost. Every sale drains the oldest lot first, so one invoice line can draw from several lots — and each movement stays traceable to the document that caused it.
Walk one item through its whole life:

Multi-warehouse
One inventory view across every location
Stock is held per warehouse, transfers move it between them, and stock in transit stays visible while it is on the road — so availability at each location is a number you can sell against.
