What is not possible, and what to do instead

Needs iVendNext cannot meet today. Not yet means a new extension point (ask for it with the request named on the card) or product work on our side (ask us). Not possible means it breaks one of the four rules (guide chapter 3); the card says what to do instead. Ask for an extension point.

Not yet: an extension point to ask for

The customer asks	What to do
A coloured row in the Desk product list for the products on promotion	A field of your own cannot take the place of a status, and a manifest cannot add a workflow to a shop's own record types (chapter 7); a workflow set in Desk was not run. Today (not run) the filter and the saved view of the card products-on-promotion-filter list the same products. Ask for P-LISTMARK.
Only the receiving store receives a transfer; only a supervisor cancels it	Today, permissions by role decide who may submit at all, whatever the field holds. Ask for P-RULES2.
A partner's voucher or PIN made when the sale is paid and printed on the receipt	Today (not run) your service can read the booked sale from the event feed and send the voucher by message or e-mail after the sale; it is not on the paper receipt. Ask for P-FULFIL.
A purchase order blocked by data our ERP holds; a goods receipt checked against the supplier's terms	Today, with a workflow: the user waits a few seconds, and your service must be up for back-office submits. Today, an outside app finds a problem only after the save. Ask for P-DOCCHECK.
A question or a check when the cashier picks an existing customer for the sale	Today the check before payment can refuse the sale at Pay. Ask for P-CAPTURE2.
A question when the quantity of a line changes, before Pay	Today the check before payment can refuse the sale at Pay (the card line-quantity-cap). Ask for P-CAPTURE3.
A rule that depends on which terminal the sale is on, beyond its POS profile	Today a rule can depend on the sale's POS profile, not on the terminal. Ask for P-CAPTURE2.
Show or relabel the discount price or the total including tax on the till	Field rules change what the till shows and asks for, never what it charges. Ask for P-FIELDS3.

Not yet: product work on our side

The customer asks	What to do
Add our own step or screen to Handheld	Today: react to what Handheld books, through the API and the event feed. Ask us: the step you need in Handheld.
Build our connector inside iVendNext's integration framework	Today: build an outside app instead. Ask us: to build the connector.
Change the order of the till's steps, or what every cashier sees	Ask us: the change to the till's steps, with the reason; it is product work, not an extension point.
Customers pay with a buy-now-pay-later provider	Ask us: a buy-now-pay-later tender in our payment connectors.
The final receipt printed while the till is offline	Today: a provisional slip offline; the final receipt once the till reconnects. Ask us: a final receipt offline.
Insurance co-payment: the insurer pays part of a prescription and the customer the rest	Ask us: our pharmacy pack's co-payment.
Keep the controlled-drug register the law asks for	Ask us: our pharmacy pack's controlled-drug register.
The next sale starts with the sales person of the last completed sale, splits included	Ask us: a Retail Setting that carries the last completed sale's sales person (and splits) into the next sale. Today the sale starts with the cashier, then the profile's default seller, and the cashier changes it. Try on a sandbox (not run): add the cashier as the sales person by default, or have the seller scan a badge at tender.
Our country's tax and e-invoicing rules	Today an outside fiscal service can record its result through a fiscal reader (the card outside-fiscal-result). Ask us: the country, through a fiscal app of ours.
A server in each store	Ask us: a store server.
Several companies, countries or currencies in one site, with connectors	One company is one country and one currency. Today: one site per company, so several countries mean several sites. Ask us: several companies in one site.

Not possible

The customer asks	What to do
A surcharge added to the sale because of the payment method or a condition	Instead: put the fee on the sale as an item the cashier adds before payment; a check before payment can refuse the sale, with your sentence, until that line is there (not run; not yet in the guide).
