No, your suppliers do not need to join the same platform for you to order online. A good restaurant ordering platform emails a clear purchase order to any supplier, reads invoices you forward or photograph, and adds live prices and catalogues only where a supplier happens to be connected.
Key takeaways
- Restaurants can order online from any supplier by sending a clear purchase order by email.
- Suppliers keep working the way they already do, so no rep has to adopt a new app.
- A good order email includes account number, delivery date, PO number, product codes and pack sizes.
- Connected suppliers add current account prices, correct product lists and their real order cut-offs.
- Phone and text orders leave nothing to check a delivery against when something is short.
- Check every delivery and invoice against the order, whichever route the order travelled.

No. A bistro buying from a butcher, a fish supplier, a bakery and three drinks reps can order from suppliers online today without a single one of them signing up to anything. Each order lands in the rep’s usual inbox as a clear purchase order, and any supplier who is connected simply adds live prices on top.
The question usually comes from a chef who has been burnt before. You tried an ordering app, and it was great for the two suppliers who were on it. The butcher, the fish guy, the bakery and the wine rep weren’t, so you were back to texts, voicemails and a notebook by the pass. One system for some suppliers and a group text for the rest isn’t a system.
Do suppliers have to sign up?
Suppliers don’t have to sign up for you to order online. The order can go to the rep’s normal email address, and from the supplier’s side it looks like any other well-written order, just clearer.
That matters because no venue buys from one supplier. A typical bistro might deal with a fruit and veg wholesaler, a butcher, a seafood supplier, a dry goods distributor, a bakery, a dairy, a coffee roaster and two or three drinks reps. Some of those will be on an ordering platform; some still run on phone calls and a paper order book. A platform that only works for some of them leaves you running two systems.
Australia has a long tail of small food businesses on both sides of the counter. Tourism Research Australia counted 89,000 cafes, restaurants and takeaway food businesses as of June 2025, and the suppliers serving them run from national distributors to one-truck operations, many of which won’t change how they take orders for one customer. Ordering by email works with all of them.
How does ordering by email work?
Ordering by email works like this: you build the order in the platform, press Send, and the supplier receives a purchase order with everything they need to pick it. Their reply, confirmation or invoice comes back to you as normal.
What a good order email contains:
| What to include | Example |
|---|---|
| Venue, delivery address, account number | Your venue, rear lane dock, acct 1042 |
| Requested delivery date and window | Friday, before 9 am |
| PO or order number | PO-0315, to match the invoice later |
| Each line: code, description, pack, quantity | ONI10 brown onions, 10 kg bag x 2 |
| Substitution instructions | Allowed with a call first |
| Contact for shorts or questions | Head chef, mobile number |
Pack sizes are where orders go wrong. "2 x 10 kg bag" is clear; "2 onions" isn’t.
Pros of ordering by email:
- Works with every supplier, from day one.
- The supplier changes nothing about how they work.
- You get a written record of what you ordered, which is what you need when a delivery comes up short.
Cons:
- Prices on your side are only as current as the last invoice you recorded.
- No live stock availability or cut-off warnings from the supplier.
- Confirmations come back as replies, not as a status update.
What about phone and text orders?
Phone and text orders still work, but they leave nothing to check a delivery against. A voicemail left at 10 pm after service, a text that says "same as last week plus extra lemons", or an order called through to whoever answered at the warehouse: none of those tells the person at the door on Friday what should be on the pallet.
They also go wrong in predictable ways:
- The rep is on leave and the message sits unheard.
- "A box" means 5 kg to one person and 10 kg to another.
- Nobody can say later whether you ordered eight or ten.
If a supplier insists on phone orders, write the order down where the rest of your orders live, line by line, before you call. You still get the record, and the check at the door still works.
The written record is the part chefs underrate. When a carton is missing or a price looks wrong, an order you can point to is the difference between a credit and an argument. Our guide to chasing short deliveries and missing supplier credits shows how to turn that record into money back.
What changes when a supplier is connected?
A connected supplier shows you their current catalogue and your account prices, and your order lands directly in their system instead of an inbox. Connecting is a bonus, not a requirement.
What you typically gain with a connected supplier:
- Current prices for your account, so the order total is right before you send it.
- Their product list, with codes and pack sizes already correct.
- Order cut-offs and delivery days that match what the supplier actually runs.
- Fewer keying errors at the supplier’s end, because nobody retypes your email.
Price accuracy is the big one. Whether a supplier is connected or not, compare each invoice line against what you expected to pay. Email-only suppliers are no excuse for a totals-only invoice: the Australian Taxation Office says a tax invoice must describe the items sold, including quantity and price, and a supplier must provide one within 28 days if you ask (sales of $82.50 or less including GST excepted). With inflation still running (the Australian Bureau of Statistics reported food and non-alcoholic beverage prices up 3.0% in the 12 months to August 2026), last month’s price is not a safe assumption. There’s more on spotting creep line by line in how to catch supplier price rises before they eat your margin.
- Food and non-alcoholic beverage prices, 12 months to August 2026 (Australia, ABS)
- +3.0%
- Time a supplier has to provide a tax invoice once you ask (Australia, ATO)
- 28 days
How do you keep all suppliers in one place?
Keep every supplier in one list with the same details for each, whether they’re connected or ordered by email. The route an order travels shouldn’t change how you plan, check or pay.
What to hold for each supplier:
- Rep name, order email and phone.
- Order days, cut-off times and delivery days.
- Your product list with their codes, pack sizes and the price you last paid.
- Minimum order and delivery fees, if any.
- Account terms and where invoices are sent.
Then run the same routine for every supplier:
- Build orders from what you’ll actually use, not from memory.
- Check each delivery at the door against the order, line by line.
- Match the invoice against the order and the delivery before you pay.
- Raise a credit request the same day for anything short, damaged or substituted.
If typing those invoices in is the bigger job in your office, see how a restaurant can stop typing in supplier invoices. If you’re still choosing who to buy from, our guide on how a restaurant chooses a wholesale supplier covers what to look for.
How Restaurant AI Manager helps you order from suppliers online
Restaurant AI Manager, Open Pantry’s AI restaurant operations software, orders from any supplier by email, so suppliers don’t need to join. (Open Pantry is an Australian ordering and operations platform for food and beverage suppliers and the restaurants they supply, founded in 2018.) Suppliers already on Open Pantry keep your prices up to date. Setup starts with forwarding last month’s supplier invoices, so suppliers, products and prices appear, and adding each rep’s email for orders.
Forecast orders are drafted for every supplier, timed to their delivery days, and nothing goes out until you press Send. Invoices come in by forwarding the email or snapping a photo, with substitutions and price rises flagged before you pay. Ordering on Open Pantry stays free for restaurants. See the restaurant ordering platform and supplier management pages, or open the free live demo, with no sign-up, to see email ordering in a demo venue.
In summary: can you order from suppliers online if they won’t join?
Yes. You can order from suppliers online without any of them joining your platform. Email purchase orders work with every supplier, connected suppliers add current prices and catalogues, and the routine stays the same either way: a clear order, a check at the door, and an invoice matched before you pay.
Frequently asked questions
Can a restaurant order online from suppliers who are not on any ordering app?
Yes. The restaurant builds the order in its ordering platform and it is sent to the supplier's normal order email as a purchase order. The supplier picks and delivers as usual and does not need a login or a new app. Invoices can come back by email or as a photo of the paper invoice, so ordering, checking and paying all stay in one place.
What should a restaurant purchase order email to a supplier include?
Include the venue name, delivery address and your account number, the requested delivery date and any delivery window, and a PO number to match against the invoice. List each line with the supplier's product code, description, pack size, quantity and unit. Add substitution instructions and a contact name and phone number for shorts or questions.
What is the benefit of a supplier being connected to my ordering platform?
A connected supplier shares its current catalogue and your account prices, so product codes, pack sizes and order totals are right before you press send. Orders land directly in the supplier's system rather than an inbox, which cuts retyping errors at their end. You also see their real order cut-offs and delivery days. It is useful but not required to order online.
Why are phone and text orders to suppliers a problem for restaurants?
Phone and text orders leave no clear record to check a delivery against. A voicemail can go unheard while a rep is on leave, a box can mean different weights to different people, and nobody can prove later whether you ordered eight or ten. A written, line-by-line order makes short deliveries and wrong items easy to spot and easier to get credited.
How do I manage ordering from many different suppliers in one place?
Keep one supplier list with the same details for each: rep name, order email, order days and cut-offs, delivery days, your product list with codes, pack sizes and last price paid, plus minimum orders and account terms. Then run one routine for all of them: order from forecast use, check deliveries at the door, match invoices before paying, and raise credits the same day.
