A POS integration is a connection between your point-of-sale system and another piece of software, so data moves between them without anyone typing it twice. It sounds like an IT topic and it is really a labour topic.
Every missing integration shows up as a human being doing a mechanical task: a manager re-keying app orders at 7pm, a bookkeeper matching card batches to invoices on a Sunday, someone counting the walk-in and then typing the count into a spreadsheet that nobody reads. Ten connections cover almost all of it. This is the list, in the order we would switch them on, with what each one actually removes from the week.
If you are earlier in the process and still deciding what the system itself should do, start with what a restaurant POS can do across the whole operation and come back to this list. Bakeries have their own version of the shortlist, weighted towards pre-orders and production, in our guide to choosing a bakery POS system.
The Bottom Line
- Switch on ordering and marketplace integrations first. They remove the most labour and prevent the most mistakes.
- Published 2026 marketplace commissions run roughly 15% to 30% per order by plan, so the reporting integration that shows you channel profitability pays for itself (LetMenu, 2026).
- Accounting and payroll integrations save the most hours per month but the fewest service-time errors. Ordering is the reverse. Sequence accordingly.
- Before you buy any integration, ask which direction the data flows. One-way sync into a tool you then have to maintain by hand is not an integration.

What a POS integration is and how it works
Two systems connect through an API, a published interface that lets one piece of software ask another for data or hand data over. When your POS and your accounting software are integrated, the day’s sales, taxes and payment types arrive in the accounting ledger on their own.
Three shapes are worth knowing apart, because they behave differently when something breaks.
- Native integration. Built by your POS vendor, listed in their marketplace, usually a toggle. Easiest, least flexible.
- Middleware. A third company sits between your POS and several other services and translates. Common for delivery marketplaces.
- Custom API work. A developer wires it yourself. Full control, and you own it forever, including the maintenance.
Ask which one you are buying. A native toggle that the vendor maintains is a very different commitment from a custom connector that breaks the next time either side updates.
All three assume a system that is online and reachable, which is a real constraint on older setups and part of why a cloud POS supports growth in a way a back-office server does not.
1. Your own online ordering channel
The highest-value connection in the list, because it is the one where you keep the margin. Orders from your own website or app land directly in the POS, priced off the same menu, with no commission to a marketplace.
What it removes: the phone. Also the mispriced order, since one menu drives both channels.
What to check: whether menu edits flow from the POS out to the website automatically, or whether you maintain two menus. Two menus means a wrong price goes live eventually.
2. Third-party delivery marketplaces
This is the one most operators need and most put off. Marketplace orders arrive on a tablet the platform gave you, and without an integration someone reads that tablet and types the order into the POS by hand, during the rush, with a queue forming.
The connection consolidates DoorDash, Uber Eats and Grubhub orders into the same queue as everything else, which also means they appear in your reporting instead of sitting outside it. A counter stacked with marketplace tablets is itself one of the signs it is time to switch to an iPad POS, since a tablet-based system usually has the broader integration marketplace to begin with.
Two routes exist. Some POS vendors build marketplace connections natively. SpotOn’s restaurant POS lists DoorDash and Uber Eats integration alongside its own commission-free online ordering, handheld devices and offline mode, with published plans starting at $0 per station monthly on card-processing rates. Otherwise you use middleware: Checkmate lists integrations with Clover, NCR, Par, Revel, Square, Toast and HungerRush on the POS side and DoorDash, Grubhub, Uber Eats, Caviar, Favor, Flytrex and Ezcater on the marketplace side, and does not publish pricing. Deliverect describes more than a thousand out-of-the-box connections including Uber Eats, DoorDash, Just Eat and POS systems such as Square, Lightspeed and Clover, and also quotes on request.
What it removes: hand-keying, and the order that goes out with the wrong items because someone misread a screen.
What to check: whether menu and availability push outward too. Marking an item sold out in the POS should take it off the marketplaces, or you will keep selling something you do not have.
3. Delivery dispatch and driver routing
Once orders are in one queue, something has to get them to doors. This connection links the POS to whatever handles your delivery leg (in-house driver tools, routing software, or a delivery provider’s platform), so an order marked ready carries its address, items and timing to the person driving.
What it removes: the clipboard at the pass, and the phone call asking where an order is.
What to check: whether status flows back. A dispatch integration that sends orders out but returns nothing leaves you blind on the half of the journey customers care about.
This is the point where POS capability usually runs out. Order management and physical delivery are different disciplines, and past a few runs a day the second one needs its own system. Metrobi works on that half for food, floral, catering and wholesale businesses, with multi-stop route optimization and the option to work with the same drivers over time. It runs across major US metros, and courier services in Houston is one of them, with the same service operating in other metro areas.
4. Accounting software
Daily sales totals, tax collected, tips, payment types and discounts flow into the ledger without a manual journal entry.
What it removes: several hours a month of reconciliation, and the month-end scramble to explain a variance nobody can reconstruct.
What to check: the mapping. Someone has to decide which POS category lands in which account the first time, and a sloppy map produces tidy-looking books that are wrong.
5. Inventory and purchasing
Sales decrement stock by recipe, so a sold burger subtracts a bun, a patty and a slice of cheese. Purchase invoices come in the other side and update costs.
What it removes: blind ordering, and the slow leak of food cost nobody notices until the quarter closes.
What to check: how much recipe setup it needs before it tells you anything. This is the integration most likely to be switched on, half-configured, and quietly abandoned. Budget the setup time honestly or skip it for now.
6. Payment processing
Often bundled with the POS rather than integrated, which is exactly why it belongs on the list: the processing rate usually costs more than the software subscription. Integrated processing also means refunds, tips and chargebacks land back against the original ticket.
What it removes: end-of-day tie-outs between a separate terminal and the POS. It also closes a gap that matters for restaurant loss prevention, since every refund and void stays attached to an original ticket and an employee rather than living on a separate device.
What to check: the effective rate at your real mix and volume, and whether you can leave. Processing lock-in is the most common hidden cost in a POS contract, and more than nine in ten operators already cite swipe fees among their significant challenges (National Restaurant Association, 2026).
7. Payroll and scheduling
Clock-in data from the POS becomes hours in payroll, and the schedule you built shows up on the terminal. Sales data lets you schedule against forecast demand rather than last week’s guess.
What it removes: transcribing timesheets, and the argument about whether someone clocked out.
What to check: whether tips, breaks and overtime rules transfer correctly for your state. This is the integration where a small error becomes a compliance problem rather than an inconvenience.
8. Loyalty, CRM and email
Guest records build from transactions, so you can see a customer’s order history and reach the people who ordered twice and then stopped.
What it removes: the gap between having thousands of customers and having a list of them.
What to check: whether marketplace orders contribute customer data. Usually they do not, by design, which is the real cost of renting someone else’s demand.
9. Reservations and waitlist
For dining rooms, the booking platform and the POS should share one view: table status, covers, turn times, and the guest record attached to the check.
What it removes: the host holding two screens and trusting neither.
What to check: whether table status updates in both directions in real time. Our guide to choosing a restaurant reservation system covers how to judge that during a demo instead of after signing.
10. Reporting and business intelligence
The POS already records everything. A reporting layer pulls it into one view, and across multiple locations into one comparable view.
What it removes: exporting spreadsheets, and the suspicion that two reports disagree.
At a group this becomes its own product category. Restroworks’ restaurant reporting software advertises more than 200 customisable reports with same-store sales comparison and delivery-aggregator performance analysis for multi-outlet operators, and quotes pricing separately rather than on the page.
What to check: whether it reports channel-level profitability rather than just revenue. Revenue by channel will tell you marketplaces are growing. Margin by channel tells you whether that is good news. If you want the manual version first, our five-step POS report routine gets you most of the way with the reports you already have.
Which integrations to switch on first
Priority is about where the work currently sits, not how impressive the feature sounds.
| Integration | Labour saved | Error risk removed | Setup effort |
|---|---|---|---|
| Own online ordering | High | High | Low |
| Delivery marketplaces | High | High | Low to medium |
| Dispatch and routing | Medium | High | Medium |
| Accounting | High | Medium | Medium |
| Inventory | Medium | Medium | High |
| Payments | Low | Medium | Low |
| Payroll and scheduling | High | Medium | Medium |
| Loyalty and CRM | Low | Low | Low |
| Reservations | Medium | Medium | Low |
| Reporting | Medium | Low | Low |
Rows one and two first, every time. They cut mistakes during service, which is when mistakes cost the most. Accounting and payroll next, because they return the most hours. Inventory last of the big ones, since its payoff depends entirely on setup you have to complete.
Three questions before you buy any of them
Hardware and platform choices shape what is available to you, so it is worth checking these before signing anything.
- Is it native, middleware, or custom? Each has a different failure mode and a different owner when it breaks.
- Which direction does data flow? Two-way is an integration. One-way is an export with better marketing.
- What does it cost per month, per location, per order? Per-order fees scale with success, which is the wrong direction for a thin margin.
Some of these jobs also have a phone-shaped answer rather than an integration-shaped one; we cover the four restaurant apps most owners end up keeping separately.
Frequently asked questions
What is a POS integration?
A connection between your POS and another system (ordering, accounting, inventory, payroll) that lets data pass between them automatically through an API, so the same information does not have to be entered twice.
Which POS integrations matter most for a restaurant?
Your own online ordering channel and third-party delivery marketplaces. Both remove hand-keying during service, which is when errors are most expensive, and both pull order data into your reporting instead of leaving it outside.
How do I connect DoorDash and Uber Eats to my POS?
Either through a native connection your POS vendor already offers, or through middleware that sits between them. Middleware providers publish their supported POS and marketplace lists; check that yours appears on both sides before committing.
Do POS integrations cost extra?
Often yes. Charges can be per month, per location, or per order, and they can come from the POS vendor, the integration provider, or both. Ask for the all-in monthly figure at your current order volume.
Can I add integrations later?
Usually, but the POS you choose sets the ceiling. Check the vendor’s integration marketplace for the names you will need in two years, not just the ones you need now.
Where to start this week
Pick the task in your week that a person does purely because two systems do not talk. For most restaurants that is marketplace order entry, and fixing it is a one-afternoon job with an immediate payoff.
Then do the boring one, accounting, because it returns hours every month and no one ever regrets it. The rest can wait until those two are running clean.
