A supplier's contact details

A supplier's record holds five contact fields. Two of them are not decorative: the main email address and the WhatsApp number are what let you send them a purchase order. Without them, the sending cannot be completed.

The five fields

FieldWhat it is for
Main emailWhere purchase orders sent by email go.
Second emailCopied in on the sending. It does not stand in for the main one.
Main phoneA voice contact. It plays no part in any sending.
Second phoneA second voice contact.
WhatsAppThe number orders are sent to by messaging.

The record itself flags which ones do real work: next to the main email it says needed to send orders, and next to the WhatsApp number, needed to send orders by WhatsApp.

The main address and the copy

The main address is the order's actual recipient. The second one travels as a copy, and its typical use is internal: leaving a record in the office, or letting the sales rep who looks after the account know.

A second address does not cover for a missing main one. If the main address is empty, the order cannot be sent by email even with a second address in place.

Use the supplier's orders address rather than one particular person's: personal addresses expire as staff change, and the order is then lost without warning.

The WhatsApp number

This is the number an order is sent to by messaging. Pressing send opens the conversation with that number and the order's text ready for you to look over and send.

The order travels as text. It is the quick route for suppliers who work by messaging and do not read email as often.

The number's format, in detail

The number has to be written in international format, with the country code, as the field itself shows: +34600111222.

Written asValidWhy
+34600111222YesCountry code, no spaces or separators.
600111222NoThe country code is missing, so the number cannot be resolved.
+34 600 11 12 22Avoid itSpaces cause errors. Write it as one run of digits.
0034600111222NoThe country code needs the + sign.

When importing from Excel

Here is the commonest mistake in the whole supplier import, and the screen warns you about it expressly:

Format the WhatsApp column as text in Excel. Left as a number, the spreadsheet strips the leading + and the row is rejected.

It happens with nothing visible in Excel: the cell looks right and the sign only disappears on saving. The check is simple. If the number shows up right-aligned, Excel is treating it as a number.

The import takes five contact columns: email, second email, phone, second phone and WhatsApp. All optional.

The phone numbers

Both phone numbers are there for information: they play no part in any automatic sending. They are for having the contact to hand when you have to ring about a problem, a price difference or a delivery still outstanding.

No format is required. Even so, writing them in international format too saves editing them before dialling from a mobile.

Things that come up

What you seeWhyWhat to do
The order cannot be sent by email The record has no main email address. Fill it in. The second one does not stand in for it.
It cannot be sent by WhatsApp The number is missing or has no country code. Write it as +34600111222.
Supplier rows rejected on import The WhatsApp column lost its + because it was formatted as a number. Format it as text and import again.
The order reaches the wrong person The main address is an out-of-date personal one. Replace it with the supplier's orders mailbox.
The supplier says nothing arrived It may have landed in the junk folder, or the address is wrong. Confirm the address with the supplier and send it again.
