Invoice Management System (IMS) Software | GSTZen

Invoice Management System

Act on every invoice your suppliers file against your GSTIN. GSTZen pulls your IMS dashboard, matches it to your purchase register, and lets you accept, reject, or keep invoices pending in bulk — so your GSTR-2B reflects only the credit you actually intend to claim.

What you can do

Accept, Reject, or Keep Pending

Review each supplier invoice on the IMS dashboard and record your action, with a full history of what was decided and when.

Auto-Match with Purchase Register

Invoices that match your books exactly are marked for acceptance automatically, leaving you to review only the exceptions.

Bulk Actions

Filter by supplier, value, or match status and apply an action to hundreds of invoices at once instead of one at a time.

Recompute GSTR-2B

Regenerate GSTR-2B after your IMS actions and see the revised ITC figure before you file GSTR-3B.

Rejected Invoice Reports

Share a clear, supplier-wise record of what was rejected and why, so corrections happen quickly at the vendor's end.

How a month on IMS runs

The same four steps every period, whether you handle one GSTIN or two hundred.

1

Pull the dashboard

GSTZen fetches every invoice your suppliers have filed against your GSTIN for the period.

2

Match to your books

Each invoice is compared with your purchase register, and clean matches are set aside from the exceptions.

3

Act in bulk

Accept what is yours, reject what is not, and hold the rest — filtered and applied in one go.

4

Recompute and file

Regenerate GSTR-2B, check the revised ITC against your books, then carry it into GSTR-3B.

The three actions, and what each one does

Every invoice on the dashboard ends up in one of three states. This is what each one means for your credit.

Accept

When to use it
The invoice matches your purchase register and the credit is yours to claim.
What GSTZen does
Records the acceptance against the invoice and keeps the decision on file.
Effect on GSTR-2B
The invoice flows in as available Input Tax Credit.

Reject

When to use it
The invoice was never received, is billed to the wrong GSTIN, or carries the wrong values.
What GSTZen does
Records the rejection and lists it in the supplier-wise report you can send out.
Effect on GSTR-2B
The invoice is dropped, so the credit is not offered to you.

Keep Pending

When to use it
Goods are yet to arrive, or the invoice needs a conversation with the supplier first.
What GSTZen does
Holds the invoice and carries it forward so it stays on your list next period.
Effect on GSTR-2B
No credit this period; the invoice stays available to act on later.

No action is an action. An invoice left untouched is treated as accepted when the period closes, and the credit lands in your GSTR-2B whether or not you looked at it. GSTZen flags what is still unreviewed before that happens.
