Calculate totals and show an order summary
Display products, quantities, and the amount due before customers submit a Neartail order.
Show customers the amount their selections produce before they commit. Keep the product subtotal separate from tax, delivery fees, discounts, and the final amount due.
Start with correctly priced products
Open each product and check its selling unit, price, and option prices. A wrong product price cannot be repaired by a correct total formula.
For a generated menu, review every price and currency. Generation can introduce defaults or interpret the source differently from the way your business sells.
Use a calculated total
A generated ordering form may already contain a total field. Open its settings and review Answer → Calculate. Use the form's field picker and supported functions to maintain the calculation.
TOTAL() sums product amounts. QUANTITY() totals ordered quantities. These are different values: our three items cost $20, and a weight-based item may use a fractional quantity.
For the older Google Forms price-description setup, TOTAL(currency) identifies prices by their currency marker. For example, TOTAL("$") uses matching dollar-marked prices. Keep descriptions and choices consistent with that marker. See Neartail's TOTAL guide.
Build the final amount
Choose which components your business uses:
Final amount = product subtotal + delivery fee + tax − discount
Use separate fields when that makes the components easier to review. Insert field references with @ rather than typing their identifiers. A discount field can hold the discount amount; subtract it once from the subtotal.
See shipping, discounts, and tax calculations for those components.
Show the summary
Use the form's order-summary or bill field to display selected products and quantities. Supported calculation functions include SUMMARY() and BILL(); choose the output appropriate to the field and layout. Include customer or handoff information where it helps review.
Check a known order
Test no items, one item, several quantities, variants, and removing an item. For Willow Kitchen, two bowls at $8 and one small soup at $4 must give a $20 subtotal. Check the saved response as well as the preview so the amount your team sees matches the customer selection.
