Why record your purchases
A purchase is any bill a supplier gives you — stock for your shop, raw material, packing boxes, even the courier's freight bill. Recording them here does three useful things: it tracks the GST you paid (which you can claim back as input tax credit if you're GST-registered), it shows who you still owe money to, and it feeds your Books & Tax so your profit numbers are real, not guesses.
Find it under your site's sidebar as Purchases (open your site from My Websites), or from the Books & Tax page.
Recording a purchase
Every purchase needs a vendor (the supplier who billed you), so add the vendor once and reuse them on every future bill — see Vendors.
Tap + New Purchase
On the Purchases page. If your vendor list is empty, the page asks you to add a vendor first.
Pick the vendor, invoice number and date
Type the invoice number exactly as printed on the bill — that's what GST matching uses later. Unregistered vendor (no GSTIN)? That's fine — the page just reminds you that reverse charge can apply on a few notified services like transport (GTA) or advocate fees.
Choose how to enter the amounts
- Quick total — one amount, one GST rate. Type the bill total (including GST) and pick the rate; the tax portion is worked out for you. 30 seconds for the common case.
- Itemized products — one line per product with its own HSN, quantity, unit price and GST rate. Use this when a bill mixes items at different rates, or when you want the items linked to your catalog (next section).
Save
The live preview shows the taxable value and GST split before you save — the server does the final CGST/SGST vs IGST math from the states involved, so you never have to. If a bill was delivered to another state, set its place of supply on the entry and the split follows it.
If your business has more than one GST registration, a Bill for picker appears so the purchase lands under the right GSTIN. Single-registration shops never see it.
Upload the bill — and let AI fill the form (free)
The paper bill fades, tears, or disappears exactly when your CA asks for it — so attach a photo or PDF and the copy stays saved with the purchase forever.
Snap or upload the bill
The upload card sits right at the top of the New Purchase form. Photos and PDFs both work, up to 10MB. On the list you'll see a 📎 on every bill that has a copy attached, and View bill opens it from the purchase any time.
Forgot to attach it while saving? Open the purchase later and tap Upload bill on the detail page — you can also Replace bill there if you attached the wrong photo.
Tap ✨ Auto-fill from bill
The button carries a FREE chip — it costs nothing. AI reads the photo and fills the vendor (matched by GSTIN or exact name), invoice number, date, total, GST rate, and even which of your GST registrations the bill is for. If the vendor on the bill isn't in your list yet, it tells you so you can add them first.
Review, then save
The form tells you exactly how many fields were filled. Always glance over them against the bill — a crumpled or badly-lit photo can be misread, and the AI leaves a field blank rather than guess.
Auto-fill works on bill photos — for PDF bills the copy is still saved, you just type the details yourself. There's a fair-use limit of 30 scans a day per person, shared with the receipt photos you snap on the Expenses page.
Itemized bills can update your stock
When a purchase line is linked to a product in your catalog, saving the bill can add those quantities to stock and update the product's cost price — so restocking and bookkeeping become one step.
- In Itemized mode, start typing a product name and pick it from your catalog. Products with variants let you pick the exact variant (say, Red / L) so stock lands in the right place.
- Keep Add these items to my stock ticked to update stock on save. Untick it for advance or in-transit bills — you can tap Add to stock on the purchase later, when the goods actually arrive (and undo it if needed).

How purchases feed your GST credit and books
Every saved bill records the GST you paid to the vendor — that's the money you may claim back as input tax credit (ITC) when you file, and the cost side of your accounts.
GST paid, tracked per bill
The list totals the GST inside your bills for any month — the starting point for your ITC claim.
GSTR-2B matching
Upload your GSTR-2B file from the GST portal and it auto-matches against these purchases, flagging bills your supplier hasn't filed.
Books & profit
Purchases (minus their GST) count as your cost of goods in the profit & loss report — real margins, not guesswork.
180-day payment rule
GST law reverses ITC on bills left unpaid 180 days — the page warns you, so record payments as you make them.
See GSTR-2B reconciliation for the matching flow, Books & Tax for the full picture, and GST invoices for the selling side.
Finding and managing your bills
The Purchases list is built for "which bill was that?" moments — filter by month, vendor, or payment state, or search by invoice number. Badges on each row show Paid / Partial / Unpaid, reverse-charge (RCM), and returns at a glance.
Open any bill for the full detail
You get the money summary (subtotal, CGST/SGST/IGST, total), the attached bill copy, and the stock status of catalog-linked items.
Record what you've paid
Tap Edit / Add lines and set Amount paid so far. This drives the Unpaid balance on the list — and keeps you safe from the 180-day ITC reversal above.
Fix, cancel, or return
Edit lets you correct lines any time. Cancel purchase keeps the record for audit instead of deleting it. Sent goods back to the supplier? ↩ Return to vendor creates a debit note that reverses the GST credit and removes the returned items from stock — the original bill stays untouched.
A return subtracts everywhere it should: the Total / GST / Unpaid numbers on top of the list go down by the returned amount (the return row shows a purple − amount), and on the debit note itself the payment tracker reads Refund due from vendor — it's money coming back to you, adjusted in the vendor's next bill or refunded.
This prepares your data; your CA files your return. ITC eligibility has legal fine print (blocked categories, composition vendors) — when in doubt, show the bill to your accountant.
