A saved bill can be changed when a unit count, a rate, the customer or a date was wrong. SimplyERP takes the old figures off your books and posts the new ones under the same bill number, and keeps the bill as it was in Changed Bills. This page changes a sale bill; purchases and returns are changed the same way.

Find the bill

Press Alt+1 for the Transactions menu and Y for All Bills (Find a Bill). The screen starts in its Find box: type the bill number, the party, the place, a phone number or a GSTIN, and the matching bills of the year so far are listed as you type. Press ↓ to go to the list.

The All Bills list found by P/295: one credit bill to Lakshmi Devi K of Kurnool Find P/295. F4 on the highlighted bill edits it; Enter opens it first.

You can also reach the same list from a bill book’s own menu, under View / Modify / Delete / Print.

Open the bill first

Enter opens the bill. Opening it before changing it is a good habit: the customer’s Balance now is on the screen, so you can see what the change does to it afterwards.

The customer’s balance before the change: Balance now ₹5,248.00 Dr Lakshmi Devi K owes ₹5,248.00 before the change.

The saved sale bill P/295: two lines, Cypermethrin 4 units and Profenofos 3 units, net amount ₹3,260.00, with the Edit bill button ringed The saved bill: ₹3,260.00 in all. Edit bill, F4, opens it for changes.

Press F4

F4 opens the bill in the same screen you made it in, with every field filled from the saved bill.

The Edit sale P/295 screen with the customer, the two lines and the totals filled in Edit sale P/295. The Save button and every other key work as on a new bill.

Two things cannot change on a saved bill: its Type and its Book. The bill keeps its number.

The heading Edit sale P/295, No. P/295, with Type Pesticide Sales and Book P/ above the date The type and book are fixed, and so is the number.

Everything else can change. You can choose another customer, move the date or the due date, change the payment, change units, rates, discounts and batches, add lines, remove a line with Ctrl+Delete, or add a charge with Alt+C. The Stock column adds the bill’s own saved units back to what is on hand, so the bill is not counted against itself.

Change what was wrong

Here the first line should have been 6 units of Cypermethrin 10 Ec 500 Ml, not 4. Click the Units cell of line 1, type 6, and press Tab or Enter. The line’s gross becomes 1,470.00.

The first line changed to 6 units, with the gross now 1,470.00; the second line is unchanged at 3 units and 2,280.00 The Units cell is ringed. Gross is 6 × 245.00 = 1,470.00.

The totals follow as you type.

The totals after the change: taxable 3,177.96, CGST 286.02, SGST 286.02 and net amount ₹3,750.00 The net amount is now ₹3,750.00, ₹490.00 more than before.

If you change your mind, press Alt+X. It asks first, then discards what you changed, and the saved bill stays as it was. An edit you leave unfinished is kept in Drafts, and F4 on the same bill opens it again.

Save the change

F3 saves, and F10 saves and prints the bill; see Print a bill. A notice names the bill, and the saved bill opens again with the new figures.

A notice in the corner: Sale bill P/295 updated, Lakshmi Devi K, ₹3,750.00 The bill keeps its number.

The saved bill P/295 after the change: Cypermethrin 6 units, 1,470.00, net amount ₹3,750.00, and Balance now ringed at ₹5,738.00 Dr The customer’s balance is now ₹5,738.00 Dr: ₹5,248.00 plus the ₹490.00 the bill grew by.

The customer’s balance after the change: Balance now ₹5,738.00 Dr ₹5,248.00 + ₹3,750.00 − ₹3,260.00 = ₹5,738.00.

What saving does to your books

Saving a changed bill is a delete and a fresh posting in one step. If the save fails, nothing changes.

  • The old bill is first copied to Changed Bills, marked Modified.
  • The units of the old lines go back into stock, batch by batch, and the old postings are taken off the ledger.
  • The new lines are then posted as a new bill would be: the units leave stock from the batches shown, and the customer (or the cash account), the sales account and the GST accounts get the new figures. See Make a sale bill for the table of postings.
  • The bill keeps its number, its book and the time it was first made.

For this bill the customer is debited ₹3,750.00 instead of ₹3,260.00, the sales account is credited ₹3,177.96 instead of ₹2,762.70, and the CGST and SGST output accounts ₹286.02 each instead of ₹248.65. The 2 extra units of Cypermethrin leave the batch on line 1.

Some saves do less:

  • If nothing was changed, nothing is posted and nothing is recorded in Changed Bills.
  • If only the dates were changed, the bill’s postings stay as they are and move to the new date. The old dates are recorded in Changed Bills.
  • A bill that has an active e-invoice can only be changed in ways that keep what was filed: its party, date, items, quantities and amounts cannot change. Cancel the e-invoice (within 24 hours of making it) or issue a credit or debit note instead. See E-invoice and e-way bill.
  • A bill that a return names as its original bill must stay with the same party and keep at least the units the return took back. The return follows the bill’s new date.
  • If an admin PIN is set, saving a change to a saved bill asks for it.

The changed bill shows in the customer’s ledger, the stock ledger and every register and GST return, with its new figures.

See the earlier version

Every change is recorded. Press Alt+8 for Utilities and S for Changed Bills (Audit). The screen starts in its Changed from date, and the period it covers (Changed from to To) is the date of the change. Each line shows the bill’s own date, party and place, and the Change column says Modified here, or Deleted for a deleted bill. Click the Find box and type the bill number.

Changed Bills found by P/295: changed on 18-10-2026 11:24 am, Modified, bill P/295 of Lakshmi Devi K, Kurnool One change recorded for P/295.

Enter opens the bill as it was before the change. It is marked Earlier version, and Current bill takes you to the bill as it stands now.

The earlier version of P/295: Cypermethrin 4 units, 980.00, net amount ₹3,260.00, with the Earlier version label The bill as it was: ₹3,260.00. The Balance now shown is the customer’s balance today.
