- Settings
- Invoices
Step 2: Tax codes
On the Tax codes tab, choose Set up tax codes for your country to add its usual codes (check the rates with your accountant), or Add tax code to make your own: a Name (for example VAT 20% or GST 18%), what kind it is (tax charged, zero-rated, exempt, out of scope or reverse charge) and its Rate %. A tax made of two parts, such as GST and PST, can have each part with its own account. Tick the default code for new lines and choose Save. Once a code is on a document its rate is fixed: archive it and add a new one when the rate changes.
Step 3: Logo, bank details and signature
Upload a Logo (PNG or JPEG, up to 500 KB) and fill in your Bank details for payment (account name and number, IFSC, bank, branch, UPI ID), the Authorised signatory and an optional Footer. They are printed on invoices, quotations and credit notes. Choose Save GST & branding.

Issue GST tax invoices (India)
Step 1: Turn on GST
Switch on Issue GST tax invoices, enter your GSTIN and State of registration, and optionally the Legal name on tax invoices. Choose Save GST & branding. The GSTIN is checked for typing mistakes.

- Settings
- GST & branding
Note: Leave GST off outside India: invoices then print as a simple invoice with a tax column. Drafts saved before you turn GST on or off must be saved again before they are issued; issued invoices never change.
Step 2: Add your customers’ GSTINs
On a new invoice or quotation, the GST card shows the customer’s GSTIN (or Unregistered) and their default place of supply. Choose Edit GST details to enter or correct the GSTIN; the state is taken from it. A valid GSTIN already saved as the customer’s tax number is used automatically.
Step 3: HSN and SAC codes
Each line has an HSN / SAC field. It fills in from the product’s HS code, and you can change it on the line (4, 6 or 8 digits).
Step 4: Place of supply and tax split
The Place of supply defaults to the customer’s state. When it is your own state the tax is split into CGST and SGST (half the rate each); for another state it is IGST. Totals are rounded to the paisa on each line.
- For customers abroad the Supply type is Export. Tick Under LUT / bond, without payment of IGST for a zero-rated export, or leave it clear to charge IGST. Supply to SEZ works the same way.
- Tick Tax payable on reverse charge when the customer pays the tax: it is shown on the invoice but not added to the total.
Step 5: The printed tax invoice
Print / Save as PDF shows “Tax Invoice” (or “Bill of Supply” when nothing is taxed), your logo, GSTIN and state, the customer’s GSTIN and the place of supply, HSN/SAC per line, CGST and SGST or IGST, a tax summary by HSN and rate, the amount in words (in lakh and crore for rupees), your bank details, a declaration and Authorised Signatory. The customer’s online link shows the same page.
Note: If your business must issue e-invoices or e-way bills, Qlomack generates the JSON for upload on the government portal; record the IRN and QR back and they print on the invoice. GST return files are in Accounts & Invoicing → GST returns. Qlomack does not file anything on the portals itself.
Step 6: GST summary
Pick a period to see outward supplies on GST invoices by section (B2B, B2C, exports, SEZ) and rate, by HSN/SAC and rate, and the credit notes issued. Choose Export CSV for your own checks; the GSTR-1 JSON and GSTR-3B figures are under GST returns.

Step 2: Send it
Choose Send quotation to email it with a link to view it online, or Mark as sent from More actions if you sent it another way. Print / Save as PDF gives the printed quotation.
Step 3: Record the answer and invoice it
Choose Mark accepted or, from More actions, Mark declined. A sent quotation past its date shows as Expired; edit it to extend the date if the customer still wants to go ahead. On an accepted quotation, choose Convert to invoice to create a draft invoice with the same lines, GST details and terms.

Step 1: Create a draft
Choose New invoice and pick the Customer; their terms and currency fill in. Add a Reference if they gave you one. Add lines with Add line, choosing a product or typing a description, with quantity, price, discount and tax. Choose Create draft.

Leave Email the invoice to the customer now ticked to email it to the customer’s email address with a link to view it online.
Note: The invoice is emailed only if you leave that box ticked, the customer has an email address and email is set up for the platform. Otherwise choose Print / Save as PDF, or copy the invoice’s link, and send it yourself.
Step 3: Send it to the customer
On an issued invoice, choose Send invoice. Check To (separate several addresses with commas), add any CC addresses, edit the Subject and Message, and keep Include a link to view the invoice online ticked. Choose Send invoice.
- Sent to customer on the invoice lists every email with its delivery status: queued, sent, failed or not sent because email isn’t set up.
- The online link opens a read-only copy of the invoice with your payment instructions, without signing in. Choose Copy link to share it yourself, or Revoke link to stop it working at once.
- Payment reminders include the link while the invoice has one.
Record payments
Step 1: Record a payment you’ve received
On the invoice, choose Record payment. Enter the Amount (a part payment is fine), Payment date, Method (Cash, Bank transfer, Cheque, Card, UPI, Online or Other) and a Reference such as the UPI or cheque number.
- The invoice shows Partially paid until the balance is cleared, then Paid.
- A payment recorded by mistake can be voided with a reason.
Note: Qlomack records payments; it doesn’t collect them. Payment gateway connections for invoices are not available yet.
Follow up unpaid invoices
Step 1: See who owes what

Step 1: Issue a credit note
Issued invoices can’t be edited. On the invoice, open More actions and choose Issue credit note. Enter the Reason, Amount before tax and Tax %, and it reduces the balance due. On a GST invoice the credit note’s tax is split the same way as the invoice (CGST and SGST, or IGST). Choose Print next to a credit note to print it.
Step 2: Or cancel the invoice
Cancel invoice is for invoices raised in error. Void its payments and cancel its credit notes first.
Bill the same customer every period
Step 1: Create a schedule
Choose New schedule. Enter a Name, the Customer, Frequency, Next issue date and an optional End date, then add the lines. Choose Create schedule.
