Suppliers

Everyone your hotel pays, and what you still owe each of them. The four figures above the list, the supplier page, and why a note on a supplier is worth more than a note on a bill.

A supplier is anyone your hotel pays: the food wholesaler, the linen company, the power utility, the agency that sends you guests and takes a commission, the accountant who does your quarterly filing. Every bill, expense, cheque and purchase order in the module points at one of them.

Who belongs in this list

Anyone you will owe money to, even once. If the payment is going out of the hotel's bank account and it is not payroll, it belongs to a supplier here.

Two things this list is not. It is not the customer list from the sales side, even where the same company sits on both: a travel agency that sends you guests and takes commission is a customer for what it books and a supplier for what it charges, and it needs a record on each side. And it is not a directory of contacts. Adding a supplier you never buy from does no harm beyond making the picker on every purchase form longer, which is a real cost when somebody is coding an invoice in a hurry.

The four figures above the list

Four statistics tiles above the supplier list, each an amount over a caption on a coloured bar: USD 18,150.00 over 3 Purchase orders, USD 92,977.70 over 9 Overdue, USD 316,105.30 over 30 Open Bills, and USD 142,926.00 over 11 Paid Last 30 Days.
Four numbers for the whole supplier ledger. Overdue is the one to read first.

These four cover every supplier, not the ten in front of you, and they do not change when you search or turn a page. Each counts something different, and the differences matter.

TileWhat it counts
Purchase orders Open orders only, at their full value. This is money you have committed to spend and not yet been billed for, so it appears in none of the other three.
Overdue The unpaid part of every bill whose due date has passed. This is the figure to read first, because it is the one your suppliers are already chasing.
Open Bills The unpaid part of every bill, late or not. Overdue is a subset of it, so the two are never added together.
Paid Last 30 Days What has actually left the hotel over the last thirty days against bills. It is the only backward-looking figure of the four.

Reading the list

The first ten rows of the supplier list, sorted by name. Columns read Supplier, Company Name, Email, Phone, Balance and Actions. Atlas Mechanical Services shows 30,895.70 USD, Brightpath Amenities 39,468.00 USD, GlobalStay Reservations 60,963.00 USD and Keystone Insurance Brokers 2,850.00 USD. Every row ends in a blue View/Edit link with a chevron.
One row per supplier, and the Balance column is what you still owe them rather than what you have ever spent.
  1. Balance is what this supplier is still owed across every unpaid bill. It is not what you have spent with them, and it falls to zero when you pay. A supplier you buy from weekly and settle weekly sits at zero all year.
  2. View/Edit opens the supplier page, and the chevron beside it holds the rest of the actions.
The toolbar above the supplier list. On the left a search box reading Enter Search Terms and an unticked Include inactive checkbox. On the right the text "Showing 1 to 10 of 17 entries | View", a page size dropdown set to 10, Page 1 of 2 with arrows either side, and print and export buttons.
Suppliers cannot be deleted, only deactivated, so Include inactive is how you find one again.

The list is sorted by name and searched by name, company, email or phone. Include inactive brings back the suppliers you have retired; leave it off and a deactivated supplier is invisible, which is the usual reason somebody adds a second record for a company that is already here.

The two buttons on the right export the list as a PDF or a spreadsheet. They export what the list currently holds, so a search narrows the export too.

Adding a supplier

New supplier opens a panel with six tabs. One field across all six is required.

If New supplier is not on your screen, and no row offers Edit, your role does not include the permission for them. Neither can be added from Users in System Settings today, because the screen checks for rights the role editor has no settings for, so adding and editing suppliers is available only to accounts with unrestricted access. Reading the list, its tiles and a supplier's transactions is unaffected.

The Add New Supplier panel open on its Contact tab, with six tabs across the top reading Contact, Addresses, Notes, Payments, Additional info and Custom field. Under a NAME AND CONTACT heading sit Title and Suffix, then Full Name marked with an asterisk beside Company name, then Email and Phone number, Mobile Phone and Fax number, and Other and Website.
Full Name is the only field the panel insists on. Everything else can be filled in later.
TabWhat it holds and whether it matters
Contact Names, company and every way of reaching them. Full Name, the one required field, is what every list and every picker will show, so type the trading name rather than the name of your account manager.
Addresses A billing address and a shipping address. The billing address is what a purchase order prints, so fill it in for anyone you will send one to.
Notes Free text about the account. See the notes section below, because this is the most useful tab here and the least used.
Payments How they usually take payment, their credit terms and their language. All three are recorded and shown back on the supplier page. None of them prefills a purchase form.
Additional info Sales tax registration, an hourly expense rate, the account number they know you by, and an opening balance with the date it was true. Fill the opening balance in only when you are moving an existing supplier onto Prostay mid-year.
Custom field Whatever your property has set up. Empty until somebody defines one in the accounting settings.

Starting a document from a row

The chevron beside View/Edit starts any purchase document already addressed to that supplier: Create Bill, Create Expense, Create Cheque, Create Purchase Order, Create Supplier Credit and Create CC Credit. Starting here rather than from a blank form is worth the extra click, because it is the one way to guarantee you have not coded an invoice to the wrong company.

The same menu holds View supplier, Edit supplier and Deactivate.

The supplier page

The top of the Harbour Foods Wholesale supplier page: a round HFW avatar beside the supplier name and the company name Harbour Foods Wholesale Inc, three links reading Send email, Add notes and Create Tasks, and a FINANCIAL SUMMARY panel showing 29,453.60 USD Open balance and 11,488.40 USD Overdue payment.
Open balance is everything unpaid. Overdue is the part of it that is already late.

Two figures, and the gap between them is the story. Open balance is everything unpaid, whether or not it is due yet. Overdue payment is the part that has passed its due date. A supplier with a large open balance and nothing overdue is a supplier you are paying properly on terms. When the two match, nothing you owe them has been paid on time.

The supplier rail down the left of the supplier page, one supplier per row with its balance underneath: Atlas Mechanical Services 30,895.70 USD, Brightpath Amenities 39,468.00 USD, Cellar and Vine Merchants 14,770.80 USD, Corbett and Hale LLP 4,800.00 USD, GlobalStay Reservations 60,963.00 USD, Meridian County Revenue Office 44,400.00 USD, Harbour Foods Wholesale 29,453.60 USD marked with a blue bar because it is the one open, and Keystone Insurance Brokers 2,850.00 USD.
The rail stays put while you move between suppliers, and it is sorted by balance or by name.

The rail down the left is the whole supplier list with balances, and clicking a name switches the page under it without going back. It has its own search and a Sort by name control, which by default leaves the biggest balances at the top. That default is what you want when you are working out who to pay this week.

The four tabs across the supplier page, reading Transaction list, Supplier Details, Notes and Attachments, with Transaction list selected and underlined in blue.
Four tabs. Notes is the one worth using, because it is the only place a supplier arrangement can be written down.

New transaction at the top of the page starts any of the six purchase documents for this supplier, and Edit holds Edit, Deactivate and Merge contacts.

The transaction list

The Transaction list tab on the Harbour Foods Wholesale page, ten rows. Columns read Date, Type, No., Payee, Category, Total, Bill Approval and Actions. The top row is a Bill dated 08/15/26, BILL-2026-0132, Food Cost, 5,698.00 USD, marked Partially paid. Below it sit rows marked Open, Applied, Paid and Overdue, including Supplier Credit SC-2026-0001 for 453.20 USD.
Every document you have ever raised against this supplier, whichever screen you raised it on.
  1. Type, which is how a bill, an expense, a cheque, a purchase order and a supplier credit end up legible in one list. A purchase order in this column has cost you nothing yet.
  2. Bill Approval, the status. Open means unpaid and not yet late, Overdue unpaid and late, Partially paid settled in part, Paid finished, and Applied belongs to a credit that has been used against a bill.

The date filter above the list runs from Last day to All, and each row carries the same action menu as the Expenses list, so you can open, print, duplicate or void a document without leaving the supplier.

This tab is what to open before you ring a supplier about an invoice. It holds every document either side of the argument: the bill, the credit they issued, and the payment you made.

Notes and attachments

The Notes tab of the Harbour Foods Wholesale supplier page, two notes grouped under their dates. The first, from Dana Whitfield, is headed "Price list fixed until 30 September" and warns that anything above the agreed rate on a delivery note is a keying error at their end. The second, from Alina Voss, is headed "Short delivery on 28 July". Each carries a Comments count underneath.
A note lives on the supplier, not on any one bill, which is what makes it the place for a standing arrangement.

A note takes a title and a body, records who wrote it and when, and can be commented on afterwards. That last part is what makes it worth using: a query raised in March and answered in June reads as one conversation rather than two orphaned notes.

Write down the things that are true of the supplier rather than of one document. Agreed rates and how long they hold. Who to ring when a delivery is short. Which day their statement arrives, and what period it covers. The account number they want quoted on a payment. All of that is invisible in the ledger and expensive to work out again from scratch.

The Attachments tab takes files against the supplier rather than against a document: the signed rate agreement, the insurance certificate, the contract. A supplier invoice PDF belongs on the bill instead, where whoever queries it will look for it.

Merging duplicates

The same company added twice, once as Harbour Foods and once as Harbour Foods Wholesale, with half the history on each, is the most common mess in this list. Merge contacts, under Edit on the supplier page, moves the transactions from the supplier you are looking at into one you choose, then deactivates the one you moved out of.

Deactivating and bringing one back

Suppliers cannot be deleted, which is right, because deleting one would take its bills with it and change last year's accounts. Deactivate takes them out of every picker and leaves every document exactly where it is.

If the supplier still owes you nothing but you still owe them, the confirmation says so and names the outstanding balance rather than letting you past quietly. Read that figure. Deactivating does not write the debt off and does not remove it from your payables; it only stops you raising anything new, which makes a forgotten balance harder to see. Settle first, deactivate after.

To find one again, tick Include inactive on the list. A deactivated supplier appears greyed with Activate in place of its usual actions, and reactivating puts it back in the pickers with its history intact.

Where to go next

A supplier on its own costs nothing. Recording what you spend covers the six forms that turn one into an amount you owe, and each line of those forms points at an account from the chart of accounts. When it is time to settle, paying bills is the screen that does several at once.

Common questions

  • A supplier is also a customer. Do I need two records?

    Yes. The customer list and the supplier list are separate, and nothing copies between them. A travel agency that sends you guests and charges commission needs a customer record for what it books and a supplier record for what it invoices you, so that what you owe and what you are owed never net themselves off by accident.

  • Why is a supplier’s balance lower than what I have spent with them?

    Because Balance is what is still unpaid, not what has been spent. Paid bills drop out of it, part payments reduce it, and expenses and cheques never enter it at all because they are paid the moment they are recorded. For everything you have ever raised against them, open the supplier and read the Transaction list tab.

  • I set Net 30 on the supplier and the bill came out due in thirty days anyway. Is that the same thing?

    No, and the coincidence is worth knowing about. A bill with no terms chosen defaults to thirty days from the bill date whatever the supplier record says. Choose the terms on the bill itself and the due date recalculates from them. On a supplier you have written down as Due on Receipt, leaving the field empty gives you a due date a month too late.

  • Can I delete a supplier I added by mistake?

    No. Deactivate it, and it stays in the list, out of the pickers, findable again through Include inactive. If the mistake was adding the same company twice, use Merge contacts rather than deactivating one of them, so the history ends up in one place instead of two.
