Payment Terms

A payment term is a reusable rule that decides when a customer owes you money, or when you owe a supplier. You build the terms your business actually offers — Net 30, end of month, end of the following month — and then attach one to each customer and supplier contact.

This article covers creating and removing payment terms, what each term type means for the due date, and how the term you attach to a contact flows through to the invoices and bills Qoblex raises.

What a payment term controls

A payment term does one job: it turns a document date into a due date.

When Qoblex creates an invoice for a customer, or a bill for a supplier, it looks at the payment term on that contact and calculates the due date. That due date is what tells you whether the document is overdue.

The countdown starts from the moment the invoice or bill is raised in Qoblex, not from the date of the sale order or purchase order behind it. An order you raise today and invoice next week gets a due date counted from next week.

Open Payment Terms

Open Account, then select the Payment Terms tile.

The page header is Payment Terms. The card beneath it is titled Payment Terms with the description Manage payment terms for your customers and suppliers.

Review your payment terms

The table lists every payment term on your account, one per row.

The Months column shows N/A for every type except Days End of Month the Xth, because the other two types ignore the months value.

Payment term types

There are three types. All three count Days; only the third uses Months.

Days Net

The due date is the document date plus Days. This is the plain “Net 30” style term.

An invoice dated 15 March 2026 with Days = 30 is due 14 April 2026.

Days following End of Month

Qoblex moves to the last day of the document’s month, then adds Days.

An invoice dated 15 March 2026 with Days = 30 is due 30 April 2026 — 31 March plus 30 days. Every invoice raised in March gets the same due date, which is what makes this type useful for customers you bill on a monthly cycle.

Days End of Month the Xth

Qoblex skips ahead by Months, lands on the last day of that month, then adds Days.

An invoice dated 15 March 2026 with Months = 1 and Days = 30 is due 30 May 2026 — skip one month to 30 April, then add 30 days.

Create a payment term

1. Open Account > Payment Terms.
2. Select Add New. Qoblex opens the New Payment Terms dialog.
3. Enter a name in Title. The placeholder reads Enter Payment Term Title.
4. Enter the number of days in Days. The placeholder reads Enter Number of Days.
5. Choose the calculation method in Type. The placeholder reads Select Type.
6. If you chose Days End of Month the Xth, a Months field appears. Enter the number of months to skip. The placeholder reads Enter Number of Months to skip.
7. Select Create Payment Term.

Qoblex confirms with Payment Term Created !, closes the dialog, and refreshes the list.

Select Cancel to close the dialog without saving. Cancel also clears anything you typed, so reopening the dialog starts from an empty form.

Field rules

The dialog checks these rules before it will create the term.

• Title is required, and must be between 3 and 50 characters. Too short shows Minimum 3 symbols; too long shows Maximum 50 symbols.
• Type is required. Leaving it unset shows This field is required.
• Days is required and must be a whole number of 0 or more.
• Months is required and must be a whole number of 0 or more. It is set to 0 for you and only becomes visible for Days End of Month the Xth, so you can ignore it for the other two types.

Attach a term to a customer or supplier

A payment term does nothing until it is on a contact.

1. Open Contacts, then open the customer or supplier record.
2. Go to the Advanced tab.
3. Choose the term in the Payment terms field.
4. Save the contact.

The dropdown lists the terms on this page, so a term you have just created is available immediately, and a term you have deleted is not. See Create and edit a contact.

On a brand-new contact opened from Contacts, the Payment terms dropdown is empty until the record has been saved once. Save the contact, reopen it, and the terms are there.

You can also reach the same Advanced tab and Payment terms field when you create or edit a supplier directly from a purchase order. That form lists the terms straight away, even for a supplier you are creating for the first time.

What Qoblex does automatically

• When an invoice is raised for a customer, Qoblex calculates its due date from the customer’s payment term, counting from the moment the invoice is created.
• When a bill is raised against a purchase order, Qoblex calculates its due date from the supplier’s payment term, counting from the moment the bill is created.
• When a contact has no payment term, the invoice or bill is due on the date it was raised, so it is payable immediately.
• Payment terms belong to your company only. Terms you create are never visible to another Qoblex account.

Because the due date is worked out and stored at the moment the document is created, changing or removing a payment term later does not move the due date on documents that already exist. Only documents raised afterwards use the new setting.

Delete a payment term

Select the trash icon on the term’s row. The term disappears from the list immediately.

While a delete is in progress the trash icons are disabled, so you cannot fire a second delete by mistake.

A deleted term is retired rather than erased. It disappears from this page and can no longer be picked on a contact, and invoices and bills that already reference it keep their stored due dates. But the term itself keeps working for any contact still attached to it: new invoices and bills for that contact go on being dated by the deleted term’s rules, even though the term is now invisible everywhere in Qoblex and cannot be recreated with the same identity.

So deleting a term does not detach it from anyone. Reassign first, delete second.
