Suppliers and customers

Suppliers are who you buy from, Customers are who you sell to — two twin screens with the same controls. Naming a supplier on an Incoming operation (or a customer on an Outgoing one) is what switches on payment and debt tracking for it.

The list

Control	What it does
Row	The name, the contact lines you’ve enabled, a badge when a price list is bound, and — when it isn’t zero — the outstanding balance. Hidden entries are greyed out and sink to the bottom.
Tap / swipe	Tap to edit; swiping left reveals quick buttons — view transactions, edit, hide, delete.
⋮ on a row	View transactions (every operation with this entity), Send E-mail, Send SMS, Phone Call, WhatsApp.
Search	Filter by name — typed or dictated.
Sort by	Reorder the list.
Settings	Choose what a row shows: address, e-mail, phone, notes, the balance.
Import from Excel / Export to Excel	Move the whole list in and out as a spreadsheet — how importing works.
Import from Contacts	Pull people straight from the phone’s contact book.
+	Add an entry. Without a subscription each list takes up to 10; the Customers and Suppliers premium feature lifts the limit.

The card

In form order (every field except the name is optional):

Field	What it does
Name	Required and unique — a duplicate name is refused. The button beside it fills the card from the phone’s Contacts.
Price list	Customers only: binds a selling price list to this customer. Appears only where price lists are available — currently StoDo Simple, with Use Prices on.
Discount(%)	Customers only: the customer’s percentage discount.
Address, E-mail, Phone	Contact details, each with an action button — write, message, or call without leaving the card.
Tax ID, Bank details	Company requisites.
Notes	Free-form remarks.
Hide	At the bottom of the card — see Hiding and deleting below.

With Use Prices on, the card also totals the relationship: Invoiced, Paid, and Due/pending — the same numbers the payments guide works with.

Debts at a glance

The list shows each entity’s outstanding balance right on the row, and the Reports screen breaks the same numbers out as Debts by Customer and Debts by Supplier — alongside Purchases by Supplier and Sales by Customer for turnover — reports reference.

Hiding and deleting

• An entity with operations behind it can’t be deleted — the app answers “You have transactions attached to this entity. Deletion prohibited!”.
• That’s what Hide is for: a hidden entity disappears from the pickers when you fill an operation’s Supplier or Customer field, but keeps its history and stays on this screen, greyed, until you unhide it.
